-

About Candide

-

Candide is an IRC bot written in Perl in pragma_'s spare time. -

-

Trigger

-

All of candide's commands may begin with its name or its trigger, or be followed by its name. -

The trigger character defaults to exclaimation mark [!]; the freenode instance uses a comma [,]. -

Note that commands need not be submitted to the channel; you can /msg it instead. If you /msg candide, - it will respond with a private message in return. In private message, -you do not need to specify its name or one of the trigger symbols. -

-
Examples:
- <pragma_> !hi (or ,hi if on freenode)
- <pragma_> hi, candide
- <pragma_> candide: hi
-
-

Source

-

Candide's source may be found at http://code.google.com/p/pbot2-pl/. It can be browsed at http://code.google.com/p/pbot2-pl/source/browse/#svn/trunk/.
-The URL for the source of any loaded modules may be found by using the factinfo command: -

-
 <pragma_> factinfo ##c faq
- <candide> faq: Module loaded by pragma_ on Fri Dec 31 02:34:04 2004 -> 
-           http://code.google.com/p/pbot2-pl/source/browse/trunk/modules/cfaq.pl, used 512 times (last by ecrane)
-
-

Bot Channel

-

You may test/play with the bot in the #pbot2 channel on irc.freenode.net. -

-

Directing output to a user

-

You may direct candide to prepend the nickname of a specific person -to a factoid in the channel by stating the nickname after the factoid -(if the factoid doesn't take arguments): -

-
 <pragma_> candide: version defrost
- <candide> defrost: PBot revision 387 2012-10-07
-
-
tell
-

You may also use the `tell <nick> about <command>` syntax (which is necessary if the factoid does take arguments): -

-
 <pragma_> candide: tell defrost about help cc
- <candide> defrost: To learn all about cc, see http://www.iso-9899.info/wiki/Candide#cc
-
-

Factoids

-

List of factoids

-

The most recent exported list of factoids can be found here: -http://www.iso-9899.info/candide/factoids.html. -

-

Channel namespaces

-

Factoids added in one channel may be called/triggered in another -channel or in private message, providing that the other channel doesn't -already have a factoid of the same name. -

Factoids may also be added to a special channel named .*. -Factoids that are set in this channel will be accessible to any channel, - including private messages. However, factoids that are set in a -specific channel will override factoids of the same name that are set in - the .* channel or other channels. -

For example, a factoid named 'malloc' set in ##c will be called -instead of 'malloc' set in .*, -if the factoid were triggered in ##c; otherwise, the latter 'malloc' -will be triggered if the factoid were triggered in another channel. -

Similiarily, if there were no 'malloc' factoid in the .* -namespace, but only in ##c and you attempted to use this factoid in a -channel other than ##c, that channel will invoke ##c's version of -'malloc', providing that channel doesn't have its own 'malloc' factoid. -

Likewise, if there is a 'malloc' factoid set in ##c++ and the factoid is triggered in the ##c++ channel, -then this version of 'malloc' will be called instead of the ##c or the .* factoid. -

However, if you are in a channel that doesn't have a 'malloc' -factoid and there is no 'malloc' factoid in the global .* channel, and -you attempt to call 'malloc' then the bot will display a message -notifying you that 'malloc' is ambiguous and which channels it belongs -to so that you may use the fact command to call the correct factoid. -

-

Adding a factoid

-

There are two ways to add a factoid. The first is: -

-
  <factoid> is <description>
-
-

In this case, the factoid will be created as belonging to -the channel in which the command was executed. If this is done via private message, then the factoid will belong to the special .* channel. -

-

factadd

-

The second method allows you to add a factoid to any channel. This -method is suitable to add to a specific channel from a private message: -

-
  factadd <channel> <keyword> is <description>
-
-

In this method, you may add factoids to any channel, including the special .* channel, which stands for all channels. -

Examples: -

-
  <pragma_> factadd ##c c is /say C rocks!
-  <pragma_> c is /say C rocks!
-
-

Special commands

-
/say
-

If a factoid begins with "/say " then candide will not use -the "<factoid> is <description>" format when displaying the -factoid. -

-
 Example:
-   <pragma_> hi is /say Well, hello there, $nick.
-   <candide> 'hi' added.
-   <prec> candide, hi
-   <candide> Well, hello there, prec.
-
-
/me
-

If a factoid begins with "/me " then candide will ACTION the factoid. -

-
 Example:
-   <pragma_> bounce is /me bounces around.
-   <candide> 'bounce' added.
-   <pragma_> bounce
-   *candide bounces around.
-
-
/call
-

If a factoid begins with "/call " then candide will call an existing command. -

-
 Example:
-   <pragma_> boing is /call bounce
-   <candide> 'boing' added.
-   <pragma_> boing
-   *candide bounces around.
-
-
/msg
-

If a factoid begins with "/msg <nick> " then candide will /MSG the factoid -text to <nick> -

-

Special variables

-

Currently there are three special variables: -

-
$nick
-
 $nick:  expands to the nick of the caller
-
-
$args
-
 $args:  expands to any text following the keyword
-
-
$channel
-
 $channel:  expands to the name of the channel in which the command is used
-
-

adlib list variables

-

You may create a list of adlib words by using the normal factoid creation method. -Also note that multiple words can be surrounded with double quotes to constitute one element. -

-
 Example:
-   <pragma_> colors is red green blue "bright yellow" pink "dark purple" orange
-   <candide> 'colors' added
-
-

Then you can instruct candide to pick a random word from this list to use in another factoid by -inserting the list as a variable. -

-
 Example:
-   <pragma_> sky is /say The sky is $colors.
-   <candide> 'sky' added.
-   <pragma_> sky
-   <candide> The sky is dark purple.
-   <pragma_> sky
-   <candide> The sky is green.
-
-

A practical example, creating the RTFM trigger: -

-
 <pragma_> sizes is big large tiny small huge gigantic teeny
- <candide> 'sizes' added.
- <pragma_> attacks is whaps thwacks bashes smacks punts whacks
- <candide> 'attacks' added.
- <pragma_> rtfm is /me $attacks $args with a $sizes $colors manual.
- <candide> 'rtfm' added.
- <pragma_> rtfm mauke
- * candide thwacks mauke with a big red manual.
-
-

action_with_args

-

You can use the factset command to -set a special factoid meta-data key named "action_with_args" to trigger -an alternate message if an argument has been supplied. -

-
 Example:
-   <pragma_> snack is /me eats a cookie.
-   <candide> 'snack' added.
-   <pragma_> factset #channel snack action_with_args /me gives $args a cookie.
-   <candide> [Factoids] (#channel) snack: 'action_with_args' set to '/me gives $args a cookie.'
-   <pragma_> snack
-   * candide eats a cookie.
-   <pragma_> snack orbitz
-   * candide gives orbitz a cookie.
-
-

add_nick

-

You can use the factset command to -set a special factoid meta-data key named "add_nick" to prepend the nick - of the caller to the output. This is mostly useful for modules. -

-

Deleting a factoid

-

factrem

-

forget

-

To remove a factoid, use the factrem or forget command. The syntax is: -

-
 factrem <channel> <keyword>
- forget <channel> <keyword>
-
-

Viewing/triggering a factoid

-

To view or trigger a factoid, one merely issues its keyword as a command. -

-
  <pragma_> candide, c?
-  <candide> C rocks!
-
-

Viewing/triggering another channel's factoid

-

fact

-

To view or trigger a factoid belonging to a specific channel, use the fact command: -

-
 fact <channel> <keyword> [arguments]
-
-

Aliasing a factoid

-

factalias

-

To create an factoid that acts as an alias for a command, use the -'factalias' command or '<alias> is /call <command>'. -

-
 <newalias> is /call <command>
-
-

The syntax for 'factalias' is: -

-
 factalias <channel> <new keyword> <command>
-
-
 Example:
-   <pragma_> book is /me points accusingly at $args, "Where is your book?!"
-   <candide> 'book' added.
-   <pragma_> book newbie
-   *candide points accusingly at newbie, "Where is your book?!"
-   <pragma_> rafb is /call book
-   <candide> 'rafb' added.
-   <pragma_> rafb runtime
-   *candide points accusingly at runtime, "Where is your book?!"
-
-
 Another example:
-   <pragma_> offtopic is /say In this channel, '$args' is off-topic.
-   <pragma_> offtopic C++
-   <candide> In this channel, 'C++' is off-topic.
-   <pragma_> factalias ##c C++ offtopic C++ (or: C++ is /call offtopic C++)
-   <pragma_> C++
-   <candide> In this channel, 'C++' is off-topic.
-
-

Changing a factoid

-

factchange

-

To change a factoid, use the 'factchange' command: -

-
 Usage:  factchange <channel> <keyword> s/<pattern>/<change to>/

-  <pragma_> c
-  <candide> C rocks!
-  <pragma_> factchange ##c c s/rocks/rules/
-  <candide> c changed.
-  <pragma_> c
-  <candide> C rules!
-
-

Note that the final argument is a Perl-style substitution regex. See 'man perlre'. -

-
 For instance, it is possible to append to a factoid by using:
-      'factchange channel factoid s/$/text to append/'
-
-
 Likewise, you can prepend to a factoid by using:
-      'factchange channel factoid s/^/text to prepend/'
-
-

Alternatively, you may append to a factoid by using 'is also': -

-
  <pragma_> candide, c is also See FAQ at http://www.eskimo.com/~scs/C-faq/top.html
-  <candide> Changed: c is /say C rules! ; See FAQ at http://www.eskimo.com/~scs/C-faq/top.html
-
-

factset

-

To view or set factoid meta-data, such as owner, rate-limit, etc, use the 'factset' command. -

-
 Usage:  factset <channel> <factoid> [<key> [value]]
-
-

Omit <key> and <value> to list all the keys and values -for a factoid. Specify <key>, but omit <value> to see the -value for a specific key. -

-

factunset

-

To unset factoid meta-data, use the 'factunset' command. -

-
 Usage: factunset <channel> <factoid> <key>
-
-

Finding a factoid

-

factfind

-

To search the database for a factoid, you may use the 'factfind' command. You may optionally -specify whether to narrow by channel and/or include factoid owner and/or last referenced by in the search. -

If there is only one match for the query, it will display that factoid, otherwise it will list all matches. -

-
Usage: factfind [-channel channel] [-owner nick] [-by nick] [text]
-Example:
- <pragma_> candide, factfind cast
- <candide> 3 factoids match: [##c] NULL casting dontcastmalloc
-
-

Information about a factoid

-

factinfo

-

To get information about a factoid, such as who submitted it and when, use the 'factinfo' command: -

-
 factinfo <channel> <keyword>
-
-
 <pragma_> candide, factinfo ##c NULL
- <candide> NULL: Factoid submitted by Major-Willard for all channels on Sat Jan 1 16:17:42 2005 
-           [5 years and 178 days ago], referenced 39 times (last by pragma_ on Sun Jun 27 04:40:32 2010 [5 seconds ago])
-
-

If the factoid has been submitted for the special .* channel, then it will be shown as 'submitted for all channels'. Otherwise, -it will be shown as 'submitted for #channel'. -

-

factshow

-

To see the factoid string literal, use the 'factshow' command: -

-
 factshow <channel> <keyword>
-
-
 <pragma_> factshow ##c hi
- <candide> hi: /say $greetings, $nick.
-
-

factset

-

To view factoid meta-data, such as owner, rate-limit, etc, use the 'factset' command. -

-
 Usage:  factset <channel> <factoid> [<key> [value]]
-
-

Omit <key> and <value> to list all the keys and values -for a factoid. Specify <key>, but omit <value> to see the -value for a specific key. -

-

count

-

To see how many factoids and what percentage of the database <nick> has submitted, use the 'count' command: -

-
 <pragma_> count prec
- <candide> prec has submitted 28 factoids out of 233 (12%)
- <pragma_> count twkm
- <candide> twkm has submitted 74 factoids out of 233 (31%)
- <pragma_> count pragma
- <candide> pragma has submitted 27 factoids out of 233 (11%)
-
-

histogram

-

To see a histogram of the top 10 factoid submitters, use the 'histogram' command: -

-
 <pragma_> histogram
- <candide> 268 factoids, top 10 submitters: twkm: 74 (27%) Major-Willard:              
-           64 (23%) pragma_: 40 (14%) prec: 39 (14%) defrost: 14 (5%)  
-           PoppaVic: 10 (3%) infobahn: 7 (2%) orbitz: 3 (1%) mauke: 3 
-           (1%) Tom^: 2 (1%) 
-
-

top20

-

To see the top 20 most popular factoids, use the 'top20' command. -

-

Commands

-

To see all the currently available commands, use the list commands command. -

Some commands are: -

-

Quotegrabs

-

Table of quotegrabs

-

A table of grabbed quotes can be found here: http://www.iso-9899.info/candide/quotegrabs.html -

-

grab

-

Grabs a message someone says, and adds it to the quotegrabs database. - You may grab multiple nicks/messages in one quotegrab by separating -the arguments with a plus sign (the nicks need not be different -- you -can grab multiple messages by the same nick by specifying a different -history for each grab). -

You can use the recall command to test the arguments before grabbing (please use a private message). -

-
Usage: grab <nick> [history [channel]]
-         where [history] is an optional argument that is an integral index into the recent messages OR a regular expression used to search message contents;
-         e.g., to grab the 3rd most recent message for nick, use: grab nick 3
-         OR to grab a message containing the text "pizza", use: grab nick pizza
-
-
Examples:
-
-
   <bob> Clowns are scary.
-   <pragma-> grab bob clowns
-   <candide> Quote grabbed: 1: <bob> Clowns are scary.
-
-
   <alice> Please put that in the right place.
-   <bob> That's what she said!
-   <pragma-> grab alice place + bob said
-   <candide> Quote grabbed 2: <alice> Please put that in the right place. <bob> That's what she said!
-
-
   <charlie> I know a funny programming knock-knock joke.  
-   <charlie> Knock knock!
-   <charlie> Race condition.
-   <charlie> Who's there?
-   <pragma-> grab charlie knock + charlie race + charlie there
-   <candide> Quote grabbed 3: <charlie> Knock knock! <charlie> Race condition. <charlie> Who's there?
-
-

recall

-

Recalls messages from the chat history and displays them with a relative time-stamp. -

Usage is identical to grab. -

-
 <pragma-> recall alice + bob
- <candide> [20 seconds ago] <alice> Please put that in the right place. [8 seconds ago] <bob> That's what she said!
-
-

getq

-

Retrieves and displays a specific grabbed quote from the quotegrabs database. -

-
Usage: getq <quote-id>
-
-

rq

-

Retrieves and displays a random grabbed quote from the quotegrabs database. You may filter by nick, channel and/or quote text. -

-
Usage: rq [nick regex [channel regex [text regex]]]
-       rq <nick regex> [-channel <channel regex>] [-text <text regex>]
-
-

delq

-

Deletes a specific grabbed quote from the quotegrabs database. You -can only delete quotes you have grabbed unless you are logged in as an -admin. -

-
Usage: delq <quote-id>
-
-

Modules

-

{}

-

This is just an alias for the cc command. Can take an optional nick argument in front in order to address the output to said nick. -

-
 Example:
-   <pragma_> { puts("hello"); }
-   <candide> hello
-   <pragma_> somebody: { puts("hi"); }
-   <candide> somebody: hi
-
-

cc

-

Code compiler (and executor). This command will compile and execute -user-provided code in a number of languages, and then display the -compiler and/or program output. -

The program is executed within a gdb debugger instance, which may - be interacted with via the gdb macros described below or with the -gdb("command") function. -

The compiler and program are executed inside a virtual machine. -After each run, the virtual machine is restored to a previous state. No - system calls have been disallowed. You can write to and read from the -filesystem, provided you do it in the same program. The network cable -has been unplugged. You are free to write and test any code you like. -Have fun. -

Uses gcc 4.9.0 and gdb 7.7. -

-
Usage
-
 Usage: cc [compiler options] [-paste] [-nomain] [-lang=<language>] <code> [-input=<stdin input>]
-        cc <run|undo|show|paste|copy|replace|prepend|append|remove|s/// [and ...]>
-        cc <diff>
-        [nick] { <same as above without the cc in front> }
-
-
  • You can pass any gcc compiler options. By default, -Wall -Wextra -std=c11 -pedantic are passed unless an option is specified. -
  • The -paste option will pretty-format and paste the code/output - to a paste site and display the URL (useful to preserve newlines in -output, and to refer to line-numbers). -
  • The -nomain flag will prevent the code from being wrapped with a main() function. -
  • The -input=<stdin input> option provides STDIN input -(i.e., scanf(), getc(stdin), etc.); MUST be the last option after any -code (otherwise the code will be considered to be input). -
  • The run, undo, show, replace, etc commands are part of interactive-editing. See below. -
  • The diff command can be used to display the differences between the two most recent snippets. -
  • You can use { } instead of cc; the options/flags/comments must - be inside the braces. Can take an optional nick argument in front in -order to address the output to said nick. -
-
Supported Languages
-

The -lang option accepts the following languages: C, C99 and C11. -Alternatively, you may use the -std=<c89|gnu89|c99|gnu99|etc> -compiler option to specify which standard to follow. -

Support for additional languages coming soon. -

-
Default Language
-

The default language (e.g., without an explicit -lang or -std option) - is C11 pedantic; which is gcc -Wall -Wextra -std=c11 -pedantic. -

-
Disallowed system calls
-

None. The network cable has been unplugged. Other than that, anything goes. Have fun. -

-
Program termination with no output
-

If there is no output, information about the local variables will be displayed. -

-
 <pragma_> cc int x = 5, y = 16; x ^= y, y ^= x, x ^= y;
- <candide> pragma_: <no output: x = 16; y = 5>
-
-
 <pragma_> cc #include <sys/utsname.h> struct utsname u; uname(&u);
- <candide> pragma_:  <no output: u = {sysname = "Linux", nodename = "compiler", release = "3.2.0-8-generic", version = "#15-Ubuntu SMP Wed Jan 11 13:57:44 UTC 2012", machine = "x86_64",  __domainname = "(none)"}>
-
-
Abnormal program termination
-

If a signal is detected, the bot will display useful information. -

Example session: -

-
< pragma_> ,cc char *p = 0; *p = 1;
-< candide> pragma_: Program received signal 11 (SIGSEGV) at statement: *p = 1; <local variables: p = 0x0>
-
-
< pragma_> ,cc void bang() { char *p = 0, s[] = "lol"; strcpy(p, s); }  bang();
-< candide> pragma_: Program received signal 11 (SIGSEGV) in bang () at statement: strcpy(p, s); <local variables: p = 0x0, s = "lol">
-
-
< pragma_> ,cc int a = 2 / 0;
-< candide> pragma_: [In function 'main': warning: division by zero] Program received signal 8 (SIGFPE) at statement: int a = 2 / 0;
-
-
C and C++ Functionality
-
Using the preprocessor
-
Default #includes
-

These are the default includes for C11. To get the most up-to-date list of #includes, use the `cc paste` command. -

-
#define _XOPEN_SOURCE 9001
-#define __USE_XOPEN
-#include <stdio.h>
-#include <stdlib.h>
-#include <string.h>
-#include <unistd.h>
-#include <math.h>
-#include <limits.h>
-#include <sys/types.h>
-#include <stdint.h>
-#include <stdbool.h>
-#include <stddef.h>
-#include <stdarg.h>
-#include <stdnoreturn.h>
-#include <stdalign.h>
-#include <ctype.h>
-#include <inttypes.h>
-#include <float.h>
-#include <errno.h>
-#include <time.h>
-#include <assert.h>
-#include <complex.h>
-
-
Using #include
-

In C and C++, you may #include <file.h> one after another on -the same line. The bot will automatically put them on separate lines. -If you do use #include, the files you specify will replace the default -includes. You do not need to append a \n after the #include. -

-
<pragma_> cc #include <sys/utsname.h> struct utsname u; uname(&u);
-<candide> pragma_:  <no output: u = {sysname = "Linux", nodename = "compiler", release = "3.2.0-8-generic", version = "#15-Ubuntu SMP Wed Jan 11 13:57:44 UTC 2012", machine = "x86_64",  __domainname = "(none)"}>
-
-
<pragma_> cc #include <stdio.h> #include <stdlib.h> void func(void) { puts("Hello, world"); } func();
-<candide> pragma_: Hello, World
-
-

In the previous examples, only the specified includes (e.g., -<sys/utsname.h> in the first example, <stdio.h> and -<stdlib.h> in the second, will be included instead of the default -includes. -

-
Using #define
-

You can also #define macros; however, #defines require an explicit -"\n" sequence to terminate, otherwise the remainder of the line will be -part of the macro. -

-
<pragma_> cc #define GREETING "Hello, World"\n puts(GREETING);
-<candide> pragma_: Hello, World
-
-
main() Function Unnecessary
-

In C and C++, if there is no main function, then a main function will - created and wrapped around the appropriate bits of your code (unless -the -nomain flag was specified); anything outside of any functions, -excluding preprocessor stuff, will be put into this new main function. -Here's an example: -

-
 <pragma_> cc -paste int add(int a, int b) { return a + b; } printf("4 + 6 = %d -- ", add(4, 6)); int add3(int a, int b, int c) 
-           { return add(a, b) + c; } printf("7 + 8 + 9 = %d", add3(7, 8, 9));
- <candide> http://sprunge.us/ehRA?c
-
-

The -paste flag causes the code to be pretty-formatted and pasted -with output in comments to a paste site, which displays the following: -

-
#define _XOPEN_SOURCE 9001
-#define __USE_XOPEN
-#include <stdio.h>
-#include <stdlib.h>
-#include <string.h>
-#include <unistd.h>
-#include <math.h>
-#include <limits.h>
-#include <sys/types.h>
-#include <stdint.h>
-#include <stdbool.h>
-#include <stddef.h>
-#include <stdarg.h>
-#include <stdnoreturn.h>
-#include <stdalign.h>
-#include <ctype.h>
-#include <inttypes.h>
-#include <float.h>
-#include <errno.h>
-#include <time.h>
-#include <assert.h>
-#include <complex.h>
-#include <prelude.h>
-
-
-int add(int a, int b) {
-    return a + b;
-}
-
-int add3(int a, int b, int c) {
-    return add(a, b) + c;
-}
-

Embedding Newlines
-

In Assembler, you may start a newline in the code via a \n sequence or a semi-colon. -

In C and C++, #defines must be terminated by a \n sequence. -

In all other languages, you may embed a newline in the code by using |n. Yes, that's the pipe character followed by 'n'. -

-
Printing in binary/base2
-

A freenode ##c regular, Wulf, has provided a printf format specifier 'b' which can be used to print values in base2. -

-
    <Wulf> cc printf("%b", 1234567);
- <candide> 000100101101011010000111
-
-
    <Wulf> cc printf("%#'b", 1234567);
- <candide> 0001.0010.1101.0110.1000.0111
-
-
Using the GDB debugger
-

The program is executed within a gdb debugger instance, which may be interacted with via the following gdb macros. -

-
print
-

The print() macro prints the values of expressions. Useful for printing out structures and arrays. -

-
<pragma_> cc int a[] = { 1, 2, 3 }; print(a);
-<candide> pragma_: <a = {1, 2, 3}>
-
-
<pragma_> cc #include <sys/utsname.h> struct utsname u; uname(&u); print(u);
-<candide> pragma_: <u = {sysname = "Linux", nodename = "compiler", release = "3.2.0-8-generic", version = "#15-Ubuntu SMP Wed Jan 11 13:57:44 UTC 2012", machine = "x86_64",  __domainname = "(none)"}>
-
-
<pragma_> cc print(sizeof(int));
-<candide> pragma_: <sizeof(int) = 4>
-
-
<pragma_> cc print(2+2);
-<candide> pragma_: <2 + 2 = 4>
-
-
ptype
-

The ptype() macro prints the types of expressions. -

-
 <pragma_> cc int *a[] = {0}; ptype(a); ptype(a[0]); ptype(*a[0]);
- <candide> pragma_: <a = int *[1]> <a[0] = int *> <*a[0] = int>
-
-
watch
-

The watch() macro watches a variable and displays its value when it changes. -

-
<pragma_> cc int n = 0, last = 1; watch(n); while(n <= 7000) { n += last; last = n - last; } /* fibonacci */
-<candide> pragma_: <n = 1> <n = 2> <n = 3> <n = 5> <n = 8> <n = 13> <n = 21> <n = 34> <n = 55> <n = 89> <n = 144> <n = 233> <n = 377> <n = 610> <n = 987> <n = 1597> <n = 2584> <n = 4181> <n = 6765> <n = 10946>
-
-
trace
-

The trace() macro traces a function's calls, displaying passed and returned values. -

-
 <pragma_> ,cc trace(foo); char *foo(int n) { puts("Hello, world"); return "Good-bye, world"; } foo(42);
- <candide> pragma_: <entered [1] foo (n=42)>
-                    Hello, world
-                    <leaving [1] foo (n=42), returned 0x401006 "Good-bye, world">
-
-
 <pragma_> ,cc int fib2(int n, int p0, int p1) { return n == 1 ? p1 : fib2(n  - 1, p1, p0 + p1); } 
-               int fib(int n) { return n == 0 ? 0 : fib2(n, 0, 1); } 
-               trace(fib); trace(fib2); for(int i = 0; i < 20; i++) printf("%d ", fib(i));
- <candide> pragma_: <entered [1] fib (n=0)>
-                    <leaving [1] fib (n=0), returned 0>

-
gdb
-

The gdb() function takes a string argument which it passes to the gdb debugger and then displays the output if any. -

-
 <pragma_> ,cc gdb("info macro NULL");
- <candide> pragma_: <Defined at /usr/lib/gcc/x86_64-linux-gnu/4.7/include/stddef.h:402> <#define NULL ((void *)0)>
-
-
 <pragma_> ,cc void foo() { gdb("info frame"); } foo();
- <candide> pragma_: <Stack level 1, frame at 0x7fffffffe660:> rip = 0x400e28 in foo (); saved rip 0x400e43 called by frame at 0x7fffffffe680, caller of frame at 0x7fffffffe650 source language

-
-
Interactive Editing
-

The cc command supports interactive-editing. The general syntax is: cc [command]. -

Each cc snippet is saved in a buffer which is named after the channel or nick it was used in. You can use show or diff with a buffer argument to view that buffer; otherwise you can use the copy - command to copy the most recent snippet of another buffer into the -current buffer and optionally chain it with another command -- for -example, to copy the ##c buffer and paste it: cc copy ##c and paste. -

The commands are: copy, show, diff, paste, run, undo, s//, replace, prepend, append, and remove. Most of the commands may be chained together by separating them with whitespace or "and". -

The commands are described in more detail below: -

-
copy
-

To copy a snippet from another buffer, use the copy command. Other commands can optionally be chained after this command. -

-
 Usage: cc copy <buffer> [and ...]
-
-
show
-

To show the latest code in the buffer, use the show command. This command can take an optional buffer argument. -

-
 <pragma_> cc show
- <candide> pragma_: printf("Hello, world!");
-
-

This command is stand-alone and cannot be chained with other interactive-editing commands. -

-
diff
-

To see the differences between the two most recent snippets, use the diff command. This command can take an optional buffer argument. -

-
 <pragma_> cc diff
- <candide> pragma: printf("<replaced `Hello` with `Good-bye`>, <replaced `world` with `void`>");
-
-

This command is stand-alone and cannot be chained with other interactive-editing commands. -

-
paste
-

To paste the full source of the latest code in the buffer as the compiler sees it, use the paste command: -

-
 <pragma_> cc paste
- <candide> pragma_: http://some.random.paste-site.com/paste/results
-
-

This command is stand-alone and cannot be chained with other interactive-editing commands. -

-
run
-

To attempt to compile and execute the latest code in the buffer, use the run command: -

-
 <pragma_> cc run
- <candide> pragma_: Hello, world!
-
-

This command is stand-alone and cannot be chained with other interactive-editing commands. -

-
undo
-

To undo any changes, use undo. The undo command must be the first command before any subsequent commands. -

-
s//
-

To change the latest code in the buffer, use the s/regex/substitution/[gi] pattern. -

-
 <pragma_> cc s/Hello/Good-bye/ and s/world/void/
- <candide> pragma_: Good-bye, void!
- <pragma_> cc show
- <candide> pragma_: printf("Good-bye, void!");
-
-
replace
-

Alternatively, you may use the replace command. The usage is (note the required single-quotes): -

-
 cc replace [all, first, second, ..., tenth, last] 'from' with 'to'
-
-
prepend
-

Text may be prepended with the prepend command: -

-
 cc prepend 'text'
-
-
append
-

Text may be appended with the append command: -

-
 cc append 'text'
-
-
remove
-

Text may be deleted with the remove command: -

-
 cc remove [all, first, second, ..., tenth, last] 'text'
-
-

-

Flood control

-

Candide can monitor the channel for excessive rapid traffic -originating from an individual and automatically ban the offender for a -certain length of time. -

-

Message flood

-

If four (4) or more messages are sent within ten (10) seconds, the -flood control is triggered. The offender will be muted for 30 seconds -for the first offense. Each additional offense will result in the -offender being muted for a much longer period. For example, the first -offense will result in 30 seconds, the 2nd offense will be 5 minutes, -the 3rd will be 1 hour, and so on. -

-

Join flood

-

If four (4) or more JOINs are observed within thirty (30) minutes without any messages in between joins, the offender will be forwarded to another channel for a limited time: 2^(number_of_offenses + 2) hours. -

In addition to private instructions from candide, this channel -will have a /topic and ChanServ on-join message with instructions -explaining to the offender how to remove the forwarding. The -instructions are to message candide with: unbanme <channel>. -

(Any messages sent to the public channel by the user at any time -will reset their JOIN counter back to zero. The unbanme command can -only be used for the first two offenses -- the offense counter is -decremented once every 24 hours.) -

-

Enter key abuse

-

If four (4) consecutive messages are sent with ten (10) seconds or -less between individual messages and without another person speaking, an - enter-key-abuse counter is incremented. This counter will then -continue to be incremented every two (2) consecutive messages with ten -(10) seconds or less in between until another person speaks or more than - ten (10) seconds have elapsed, whereupon it returns to requiring four -(4) consecutive messages. When this counter reaches three (3) or -greater, the offender will be muted using the same timeout rules as -message flooding. This counter is automatically decremented once per -hour. -

-

Notification message

-

Candide will send the following message to the offender each offense. -

-

Message flooding

-

"You have been muted due to flooding. Please use a web paste service such as http://codepad.org for lengthy pastes. You will be allowed to speak again in $timeout." -

-

Join flooding

-

"You have been banned from $channel due to join flooding. If your -connection issues have been resolved, or this was an accident, you may -request an unban at any time by responding to this message with: unbanme - $channel, otherwise you will be automatically unbanned in $timeout." -

-

Enter key abuse

-

"You have been muted due to abusing the enter key. Please do not -split your sentences over multiple messages. You will be allowed to -speak again in $timeout." -

-

Opping/Deopping

-

ChanServ will automagically op and deop Candide when necessary. -Candide will wait until about 5 minutes have elapsed before requesting a - deop from ChanServ. -

PBot

+

About PBot

+

PBot is an IRC bot written in Perl in pragma_'s spare time. +

+

Trigger

+

All of PBot's commands may begin with its name or its trigger, or be followed by its name. +

The trigger character defaults to exclaimation mark [!]. +

Note that commands need not be submitted to the channel; you can /msg it instead. If you /msg PBot, it will respond with a private message in return. In private message, you do not need to specify its name or one of the trigger symbols. +

+
Examples:
+ <pragma_> !hi
+ <pragma_> hi, PBot
+ <pragma_> PBot: hi
+
+

Source

+

PBot's source may be found at these repositories: +

+
* https://github.com/pragma-/pbot
+* https://code.google.com/p/pbot2-pl/source/browse/
+* https://bitbucket.org/pragmasoft/pbot/src
+* https://gitorious.org/pbot/pbot/
+
+

The URL for the source of any loaded modules may be found by using the factinfo command: +

+
 <pragma_> factinfo ##c faq
+ <PBot> faq: Module loaded by pragma_ on Fri Dec 31 02:34:04 2004 -> 
+           https://github.com/pragma-/pbot/blob/master/modules/cfaq.pl, used 512 times (last by ecrane)
+
+

Bot Channel

+

You may test/play with the bot in the #pbot2 channel on irc.freenode.net. +

+

Directing output to a user

+

You may direct PBot to prepend the nickname of a specific person to a factoid in the channel by stating the nickname after the factoid (if the factoid doesn't take arguments): +

+
 <pragma_> PBot: version defrost
+ <PBot> defrost: PBot revision 387 2012-10-07
+
+
tell
+

You may also use the `tell <nick> about <command>` syntax (which is necessary if the factoid does take arguments): +

+
 <pragma_> PBot: tell defrost about help cc
+ <PBot> defrost: To learn all about cc, see http://www.iso-9899.info/wiki/PBot#cc
+
+

Factoids

+

List of factoids

+

The most recent exported list of factoids can be found here: +http://www.iso-9899.info/PBot/factoids.html. +

+

Channel namespaces

+

Factoids added in one channel may be called/triggered in another channel or in private message, providing that the other channel doesn't already have a factoid of the same name. +

Factoids may also be added to a special channel named global. Factoids that are set in this channel will be accessible to any channel, including private messages. However, factoids that are set in a specific channel will override factoids of the same name that are set in the global channel or other channels. +

For example, a factoid named 'malloc' set in ##c will be called instead of 'malloc' set in global, +if the factoid were triggered in ##c; otherwise, the latter 'malloc' will be triggered if the factoid were triggered in another channel. +

Similiarily, if there were no 'malloc' factoid in the global namespace, but only in ##c and you attempted to use this factoid in a channel other than ##c, that channel will invoke ##c's version of 'malloc', providing that channel doesn't have its own 'malloc' factoid. +

Likewise, if there is a 'malloc' factoid set in ##c++ and the factoid is triggered in the ##c++ channel, +then this version of 'malloc' will be called instead of the ##c or the global factoid. +

However, if you are in a channel that doesn't have a 'malloc' factoid and there is no 'malloc' factoid in the global channel, and you attempt to call 'malloc' then the bot will display a message notifying you that 'malloc' is ambiguous and which channels it belongs to so that you may use the fact command to call the correct factoid. +

+

Adding a factoid

+

factadd

+
 Usage:
+   factadd <channel> <keyword> is <description>
+
+

To add a factoid to the global channel, use global as the channel. +

+
 Example:
+   <pragma_> factadd ##c c is /say C rocks!
+
+

Special commands

+
/say
+

If a factoid begins with "/say " then PBot will not use +the "<factoid> is <description>" format when displaying the +factoid. +

+
 Example:
+   <pragma_> factadd global hi is /say Well, hello there, $nick.
+   <PBot> 'hi' added to the global channel
+   <prec> PBot, hi
+   <PBot> Well, hello there, prec.
+
+
/me
+

If a factoid begins with "/me " then PBot will ACTION the factoid. +

+
 Example:
+   <pragma_> factadd global bounce is /me bounces around.
+   <PBot> 'bounce' added to the global channel
+   <pragma_> bounce
+   *PBot bounces around.
+
+
/call
+

If a factoid begins with "/call " then PBot will call an existing command. +

+
 Example:
+   <pragma_> factadd global boing is /call bounce
+   <PBot> 'boing' added to the global channel
+   <pragma_> boing
+   *PBot bounces around.
+
+
/msg
+

If a factoid begins with "/msg <nick> " then PBot will /MSG the factoid +text to <nick> +

+

Special variables

+

Currently there are three special variables: +

+
$nick
+
 $nick:  expands to the nick of the caller
+
+
$args
+
 $args:  expands to any text following the keyword
+
+
$channel
+
 $channel:  expands to the name of the channel in which the command is used
+
+

adlib list variables

+

You may create a list of adlib words by using the normal factoid creation method. +Also note that multiple words can be surrounded with double quotes to constitute one element. +

+
 Example:
+   <pragma_> factadd global colors is red green blue "bright yellow" pink "dark purple" orange
+   <PBot> 'colors' added to the global channel
+
+

Then you can instruct PBot to pick a random word from this list to use in another factoid by +inserting the list as a variable. +

+
 Example:
+   <pragma_> factadd global sky is /say The sky is $colors.
+   <PBot> 'sky' added to the global channel
+   <pragma_> sky
+   <PBot> The sky is dark purple.
+   <pragma_> sky
+   <PBot> The sky is green.
+
+

A practical example, creating the RTFM trigger: +

+
 <pragma_> factadd global sizes is big large tiny small huge gigantic teeny
+ <PBot> 'sizes' added to the global channel
+ <pragma_> factadd global attacks is whaps thwacks bashes smacks punts whacks
+ <PBot> 'attacks' added to the global channel
+ <pragma_> factadd global rtfm is /me $attacks $args with a $sizes $colors manual.
+ <PBot> 'rtfm' added to the global channel
+ <pragma_> rtfm mauke
+ * PBot thwacks mauke with a big red manual.
+
+

action_with_args

+

You can use the factset command to set a special factoid meta-data key named "action_with_args" to trigger an alternate message if an argument has been supplied. +

+
 Example:
+   <pragma_> factadd global snack is /me eats a cookie.
+   <PBot> 'snack' added to the global channel
+   <pragma_> factset global snack action_with_args /me gives $args a cookie.
+   <PBot> [Factoids] (global) snack: 'action_with_args' set to '/me gives $args a cookie.'
+   <pragma_> snack
+   * PBot eats a cookie.
+   <pragma_> snack orbitz
+   * PBot gives orbitz a cookie.
+
+

add_nick

+

You can use the factset command to set a special factoid meta-data key named "add_nick" to prepend the nick of the caller to the output. This is mostly useful for modules. +

+

Deleting a factoid

+

factrem

+

forget

+

To remove a factoid, use the factrem or forget command. The syntax is: +

+
 factrem <channel> <keyword>
+ forget <channel> <keyword>
+
+

Viewing/triggering a factoid

+

To view or trigger a factoid, one merely issues its keyword as a command. +

+
  <pragma_> PBot, c?
+  <PBot> C rocks!
+
+

Viewing/triggering another channel's factoid

+

fact

+

To view or trigger a factoid belonging to a specific channel, use the fact command: +

+
 fact <channel> <keyword> [arguments]
+
+

Aliasing a factoid

+

factalias

+

To create an factoid that acts as an alias for a command, use the 'factalias' command or '<alias> is /call <command>'. +

+
 <newalias> is /call <command>
+
+

The syntax for 'factalias' is: +

+
 factalias <channel> <new keyword> <command>
+
+
 Example:
+   <pragma_> factadd ##c book is /me points accusingly at $args, "Where is your book?!"
+   <PBot> 'book' added to ##c
+   <pragma_> book newbie
+   *PBot points accusingly at newbie, "Where is your book?!"
+   <pragma_> factadd ##c rafb is /call book
+   <PBot> 'rafb' added to ##c
+   <pragma_> rafb runtime
+   *PBot points accusingly at runtime, "Where is your book?!"
+
+
 Another example:
+   <pragma_> factadd ##c offtopic is /say In this channel, '$args' is off-topic.
+   <pragma_> offtopic C++
+   <PBot> In this channel, 'C++' is off-topic.
+   <pragma_> factalias ##c C++ offtopic C++ (alternatively: factadd ##c C++ is /call offtopic C++)
+   <pragma_> C++
+   <PBot> In this channel, 'C++' is off-topic.
+
+

Moving/renaming a factoid

+

factmove

+

To rename a factoid or move a factoid to a different channel, use the 'factmove' command: +

+
 Usage:  factmove <source channel> <source factoid> <target channel/factoid> [target factoid]
+
+

If three arguments are given, the factoid is renamed in the source channel. If four arguments are given, the factoid is moved to the target channel with the target name. +

+

Changing a factoid

+

factchange

+

To change a factoid, use the 'factchange' command: +

+
 Usage:  factchange <channel> <keyword> s/<pattern>/<change to>/

+  <pragma_> c
+  <PBot> C rocks!
+  <pragma_> factchange ##c c s/rocks/rules/
+  <PBot> c changed.
+  <pragma_> c
+  <PBot> C rules!
+
+

Note that the final argument is a Perl-style substitution regex. See 'man perlre'. +

+
 For instance, it is possible to append to a factoid by using:
+      'factchange channel factoid s/$/text to append/'
+
+
 Likewise, you can prepend to a factoid by using:
+      'factchange channel factoid s/^/text to prepend/'
+
+

Alternatively, you may append to a factoid by using 'is also': +

+
  <pragma_> PBot, c is also See FAQ at http://www.eskimo.com/~scs/C-faq/top.html
+  <PBot> Changed: c is /say C rules! ; See FAQ at http://www.eskimo.com/~scs/C-faq/top.html
+
+

factset

+

To view or set factoid meta-data, such as owner, rate-limit, etc, use the 'factset' command. +

+
 Usage:  factset <channel> <factoid> [<key> [value]]
+
+

Omit <key> and <value> to list all the keys and values for a factoid. Specify <key>, but omit <value> to see the value for a specific key. +

+

factunset

+

To unset factoid meta-data, use the 'factunset' command. +

+
 Usage: factunset <channel> <factoid> <key>
+
+

Finding a factoid

+

factfind

+

To search the database for a factoid, you may use the 'factfind' command. You may optionally +specify whether to narrow by channel and/or include factoid owner and/or last referenced by in the search. +

If there is only one match for the query, it will display that factoid, otherwise it will list all matches. +

+
Usage: factfind [-channel channel] [-owner nick] [-by nick] [text]
+Example:
+ <pragma_> PBot, factfind cast
+ <PBot> 3 factoids match: [##c] NULL casting dontcastmalloc
+
+

Information about a factoid

+

factinfo

+

To get information about a factoid, such as who submitted it and when, use the 'factinfo' command: +

+
 factinfo <channel> <keyword>
+
+
 <pragma_> PBot, factinfo ##c NULL
+ <PBot> NULL: Factoid submitted by Major-Willard for all channels on Sat Jan 1 16:17:42 2005 
+           [5 years and 178 days ago], referenced 39 times (last by pragma_ on Sun Jun 27 04:40:32 2010 [5 seconds ago])
+
+

If the factoid has been submitted for the special global channel, then it will be shown as 'submitted for all channels'. Otherwise, +it will be shown as 'submitted for #channel'. +

+

factshow

+

To see the factoid string literal, use the 'factshow' command: +

+
 factshow <channel> <keyword>
+
+
 <pragma_> factshow ##c hi
+ <PBot> hi: /say $greetings, $nick.
+
+

factset

+

To view factoid meta-data, such as owner, rate-limit, etc, use the 'factset' command. +

+
 Usage:  factset <channel> <factoid> [<key> [value]]
+
+

Omit <key> and <value> to list all the keys and values for a factoid. Specify <key>, but omit <value> to see the value for a specific key. +

+

count

+

To see how many factoids and what percentage of the database <nick> has submitted, use the 'count' command: +

+
 <pragma_> count prec
+ <PBot> prec has submitted 28 factoids out of 233 (12%)
+ <pragma_> count twkm
+ <PBot> twkm has submitted 74 factoids out of 233 (31%)
+ <pragma_> count pragma
+ <PBot> pragma has submitted 27 factoids out of 233 (11%)
+
+

histogram

+

To see a histogram of the top 10 factoid submitters, use the 'histogram' command: +

+
 <pragma_> histogram
+ <PBot> 268 factoids, top 10 submitters: twkm: 74 (27%) Major-Willard:              
+           64 (23%) pragma_: 40 (14%) prec: 39 (14%) defrost: 14 (5%)  
+           PoppaVic: 10 (3%) infobahn: 7 (2%) orbitz: 3 (1%) mauke: 3 
+           (1%) Tom^: 2 (1%) 
+
+

top20

+

To see the top 20 most popular factoids, use the 'top20' command. +

+

Commands

+

To see all the currently available commands, use the list commands command. +

Some commands are: +

+

Quotegrabs

+

Table of quotegrabs

+

A table of grabbed quotes can be found here: http://www.iso-9899.info/PBot/quotegrabs.html +

+

grab

+

Grabs a message someone says, and adds it to the quotegrabs database. You may grab multiple nicks/messages in one quotegrab by separating the arguments with a plus sign (the nicks need not be different -- you can grab multiple messages by the same nick by specifying a different history for each grab). +

You can use the recall command to test the arguments before grabbing (please use a private message). +

+
Usage: grab <nick> [history [channel]] [+ ...]
+         where [history] is an optional argument regular expression used to search message contents;
+         e.g., to grab a message containing the text "pizza", use: grab nick pizza
+
+
Examples:
+
+
   <bob> Clowns are scary.
+   <pragma-> grab bob clowns
+   <PBot> Quote grabbed: 1: <bob> Clowns are scary.
+
+
   <alice> Please put that in the right place.
+   <bob> That's what she said!
+   <pragma-> grab alice place + bob said
+   <PBot> Quote grabbed 2: <alice> Please put that in the right place. <bob> That's what she said!
+
+
   <charlie> I know a funny programming knock-knock joke.  
+   <charlie> Knock knock!
+   <charlie> Race condition.
+   <charlie> Who's there?
+   <pragma-> grab charlie knock + charlie race + charlie there
+   <PBot> Quote grabbed 3: <charlie> Knock knock! <charlie> Race condition. <charlie> Who's there?
+
+

recall

+

Recalls messages from the chat history and displays them with a relative time-stamp. +

Usage: recall <[nick [history [channel]]] [-c,channel <channel>] [-t,text,h,history <history>] [+ ...]> +

+
 <pragma-> recall alice + bob
+ <PBot> [20 seconds ago] <alice> Please put that in the right place. [8 seconds ago] <bob> That's what she said!
+
+

getq

+

Retrieves and displays a specific grabbed quote from the quotegrabs database. +

+
Usage: getq <quote-id>
+
+

rq

+

Retrieves and displays a random grabbed quote from the quotegrabs database. You may filter by nick, channel and/or quote text. +

+
Usage: rq [nick [channel [text]]] [-c,--channel <channel>] [-t,--text <text>]
+
+

delq

+

Deletes a specific grabbed quote from the quotegrabs database. You can only delete quotes you have grabbed unless you are logged in as an admin. +

+
Usage: delq <quote-id>
+
+

Modules

+

{}

+

This is just an alias for the cc command. Can take an optional nick argument in front in order to address the output to said nick. +

+
 Example:
+   <pragma_> { puts("hello"); }
+   <PBot> hello
+   <pragma_> somebody: { puts("hi"); }
+   <PBot> somebody: hi
+
+

cc

+

Code compiler (and executor). This command will compile and execute user-provided code in a number of languages, and then display the compiler and/or program output. +

The program is executed within a gdb debugger instance, which may be interacted with via the gdb macros described below or with the gdb("command") function. +

The compiler and program are executed inside a virtual machine. After each run, the virtual machine is restored to a previous state. No system calls have been disallowed. You can write to and read from the filesystem, provided you do it in the same program. The network cable has been unplugged. You are free to write and test any code you like. Have fun. +

Uses gcc 4.9.0 and gdb 7.7. +

+
Usage
+
 Usage: cc [compiler options] [-paste] [-nomain] [-lang=<language>] <code> [-input=<stdin input>]
+        cc <run|undo|show|paste|copy|replace|prepend|append|remove|s/// [and ...]>
+        cc <diff>
+        [nick] { <same as above without the cc in front> }
+
+
  • You can pass any gcc compiler options. By default, -Wall -Wextra -std=c11 -pedantic are passed unless an option is specified. +
  • The -paste option will pretty-format and paste the code/output to a paste site and display the URL (useful to preserve newlines in output, and to refer to line-numbers). +
  • The -nomain flag will prevent the code from being wrapped with a main() function. +
  • The -input=<stdin input> option provides STDIN input (i.e., scanf(), getc(stdin), etc.); MUST be the last option after any code (otherwise the code will be considered to be input). +
  • The run, undo, show, replace, etc commands are part of interactive-editing. See below. +
  • The diff command can be used to display the differences between the two most recent snippets. +
  • You can use { } instead of cc; the options/flags/comments must be inside the braces. Can take an optional nick argument in front in order to address the output to said nick. +
+
Supported Languages
+

The -lang option accepts the following languages: C, C99 and C11. Alternatively, you may use the -std=<c89|gnu89|c99|gnu99|etc> compiler option to specify which standard to follow. +

Support for additional languages coming soon. +

+
Default Language
+

The default language (e.g., without an explicit -lang or -std option) is C11 pedantic; which is gcc -Wall -Wextra -std=c11 -pedantic. +

+
Disallowed system calls
+

None. The network cable has been unplugged. Other than that, anything goes. Have fun. +

+
Program termination with no output
+

If there is no output, information about the local variables will be displayed. +

+
 <pragma_> cc int x = 5, y = 16; x ^= y, y ^= x, x ^= y;
+ <PBot> pragma_: <no output: x = 16; y = 5>
+
+
 <pragma_> cc #include <sys/utsname.h> struct utsname u; uname(&u);
+ <PBot> pragma_:  <no output: u = {sysname = "Linux", nodename = "compiler", release = "3.2.0-8-generic", version = "#15-Ubuntu SMP Wed Jan 11 13:57:44 UTC 2012", machine = "x86_64",  __domainname = "(none)"}>
+
+
Abnormal program termination
+

If a signal is detected, the bot will display useful information. +

Example session: +

+
< pragma_> ,cc char *p = 0; *p = 1;
+< PBot> pragma_: Program received signal 11 (SIGSEGV) at statement: *p = 1; <local variables: p = 0x0>
+
+
< pragma_> ,cc void bang() { char *p = 0, s[] = "lol"; strcpy(p, s); }  bang();
+< PBot> pragma_: Program received signal 11 (SIGSEGV) in bang () at statement: strcpy(p, s); <local variables: p = 0x0, s = "lol">
+
+
< pragma_> ,cc int a = 2 / 0;
+< PBot> pragma_: [In function 'main': warning: division by zero] Program received signal 8 (SIGFPE) at statement: int a = 2 / 0;
+
+
C and C++ Functionality
+
Using the preprocessor
+
Default #includes
+

These are the default includes for C11. To get the most up-to-date list of #includes, use the `cc paste` command. +

+
+#define _XOPEN_SOURCE 9001
+#define __USE_XOPEN
+#include <stdio.h>
+#include <stdlib.h>
+#include <string.h>
+#include <unistd.h>
+#include <math.h>
+#include <limits.h>
+#include <sys/types.h>
+#include <stdint.h>
+#include <stdbool.h>
+#include <stddef.h>
+#include <stdarg.h>
+#include <stdnoreturn.h>
+#include <stdalign.h>
+#include <ctype.h>
+#include <inttypes.h>
+#include <float.h>
+#include <errno.h>
+#include <time.h>
+#include <assert.h>
+#include <complex.h>
+
+
Using #include
+

In C and C++, you may #include <file.h> one after another on the same line. The bot will automatically put them on separate lines. If you do use #include, the files you specify will replace the default includes. You do not need to append a \n after the #include. +

+
<pragma_> cc #include <sys/utsname.h> struct utsname u; uname(&u);
+<PBot> pragma_:  <no output: u = {sysname = "Linux", nodename = "compiler", release = "3.2.0-8-generic", version = "#15-Ubuntu SMP Wed Jan 11 13:57:44 UTC 2012", machine = "x86_64",  __domainname = "(none)"}>
+
+
<pragma_> cc #include <stdio.h> #include <stdlib.h> void func(void) { puts("Hello, world"); } func();
+<PBot> pragma_: Hello, World
+
+

In the previous examples, only the specified includes (e.g., <sys/utsname.h> in the first example, <stdio.h> and <stdlib.h> in the second, will be included instead of the default includes. +

+
Using #define
+

You can also #define macros; however, #defines require an explicit "\n" sequence to terminate, otherwise the remainder of the line will be part of the macro. +

+
<pragma_> cc #define GREETING "Hello, World"\n puts(GREETING);
+<PBot> pragma_: Hello, World
+
+
main() Function Unnecessary
+

In C and C++, if there is no main function, then a main function will created and wrapped around the appropriate bits of your code (unless the -nomain flag was specified); anything outside of any functions, excluding preprocessor stuff, will be put into this new main function. Here's an example: +

+
 <pragma_> cc -paste int add(int a, int b) { return a + b; } printf("4 + 6 = %d -- ", add(4, 6)); int add3(int a, int b, int c) 
+           { return add(a, b) + c; } printf("7 + 8 + 9 = %d", add3(7, 8, 9));
+ <PBot> http://sprunge.us/ehRA?c
+
+

The -paste flag causes the code to be pretty-formatted and pasted with output in comments to a paste site, which displays the following: +

+
+#define _XOPEN_SOURCE 9001
+#define __USE_XOPEN
+#include <stdio.h>
+#include <stdlib.h>
+#include <string.h>
+#include <unistd.h>
+#include <math.h>
+#include <limits.h>
+#include <sys/types.h>
+#include <stdint.h>
+#include <stdbool.h>
+#include <stddef.h>
+#include <stdarg.h>
+#include <stdnoreturn.h>
+#include <stdalign.h>
+#include <ctype.h>
+#include <inttypes.h>
+#include <float.h>
+#include <errno.h>
+#include <time.h>
+#include <assert.h>
+#include <complex.h>
+#include <prelude.h>
+
+
+int add(int a, int b) {
+    return a + b;
+}
+
+int add3(int a, int b, int c) {
+    return add(a, b) + c;
+}
+
+int main(void) {
+    printf("4 + 6 = %d -- ", add(4, 6));
+
+    printf("7 + 8 + 9 = %d", add3(7, 8, 9));
+    return 0;
+}
+
+/************* OUTPUT *************
+4 + 6 = 10 -- 7 + 8 + 9 = 24
+************** OUTPUT *************/
+
+
Embedding Newlines
+

In Assembler, you may start a newline in the code via a \n sequence or a semi-colon. +

In C and C++, #defines must be terminated by a \n sequence. +

In all other languages, you may embed a newline in the code by using |n. Yes, that's the pipe character followed by 'n'. +

+
Printing in binary/base2
+

A freenode ##c regular, Wulf, has provided a printf format specifier 'b' which can be used to print values in base2. +

+
    <Wulf> cc printf("%b", 1234567);
+ <PBot> 000100101101011010000111
+
+
    <Wulf> cc printf("%#'b", 1234567);
+ <PBot> 0001.0010.1101.0110.1000.0111
+
+
Using the GDB debugger
+

The program is executed within a gdb debugger instance, which may be interacted with via the following gdb macros. +

+
print
+

The print() macro prints the values of expressions. Useful for printing out structures and arrays. +

+
<pragma_> cc int a[] = { 1, 2, 3 }; print(a);
+<PBot> pragma_: <a = {1, 2, 3}>
+
+
<pragma_> cc #include <sys/utsname.h> struct utsname u; uname(&u); print(u);
+<PBot> pragma_: <u = {sysname = "Linux", nodename = "compiler", release = "3.2.0-8-generic", version = "#15-Ubuntu SMP Wed Jan 11 13:57:44 UTC 2012", machine = "x86_64",  __domainname = "(none)"}>
+
+
<pragma_> cc print(sizeof(int));
+<PBot> pragma_: <sizeof(int) = 4>
+
+
<pragma_> cc print(2+2);
+<PBot> pragma_: <2 + 2 = 4>
+
+
ptype
+

The ptype() macro prints the types of expressions. +

+
 <pragma_> cc int *a[] = {0}; ptype(a); ptype(a[0]); ptype(*a[0]);
+ <PBot> pragma_: <a = int *[1]> <a[0] = int *> <*a[0] = int>
+
+
watch
+

The watch() macro watches a variable and displays its value when it changes. +

+
<pragma_> cc int n = 0, last = 1; watch(n); while(n <= 7000) { n += last; last = n - last; } /* fibonacci */
+<PBot> pragma_: <n = 1> <n = 2> <n = 3> <n = 5> <n = 8> <n = 13> <n = 21> <n = 34> <n = 55> <n = 89> <n = 144> <n = 233> <n = 377> <n = 610> <n = 987> <n = 1597> <n = 2584> <n = 4181> <n = 6765> <n = 10946>
+
+
trace
+

The trace() macro traces a function's calls, displaying passed and returned values. +

+
 <pragma_> ,cc trace(foo); char *foo(int n) { puts("Hello, world"); return "Good-bye, world"; } foo(42);
+ <PBot> pragma_: <entered [1] foo (n=42)>
+                    Hello, world
+                    <leaving [1] foo (n=42), returned 0x401006 "Good-bye, world">
+
+
 <pragma_> ,cc int fib2(int n, int p0, int p1) { return n == 1 ? p1 : fib2(n  - 1, p1, p0 + p1); } 
+               int fib(int n) { return n == 0 ? 0 : fib2(n, 0, 1); } 
+               trace(fib); trace(fib2); for(int i = 0; i < 20; i++) printf("%d ", fib(i));
+ <PBot> pragma_: <entered [1] fib (n=0)>
+                    <leaving [1] fib (n=0), returned 0>
+                    1
+                    <entered [1] fib (n=2)>
+                    <entered [2]  fib2 (n=2, p0=0, p1=1)>
+                    <entered [3]   fib2 (n=1, p0=1, p1=1)>
+                    <leaving [3]   fib2 (n=1, p0=1, p1=1), returned 1>
+                    <leaving [2]  fib2 (n=2, p0=0, p1=1), returned 1>
+                    <leaving [1] fib (n=2), returned 1>
+                    1
+                    <entered [1] fib (n=3)>
+                    <entered [2]  fib2 (n=3, p0=0, p1=1)>

+                    <leaving [2]  fib2 (n=3, p0=0, p1=1), returned 2>
+                    <leaving [1] fib (n=3), returned 2>
+                    2
+                    <entered [1] fib (n=4)>
+                    <entered [2]  fib2 (n=4, p0=0, p1=1)>

+
 <pragma_> ,cc gdb("info macro NULL");
+ <PBot> pragma_: <Defined at /usr/lib/gcc/x86_64-linux-gnu/4.7/include/stddef.h:402> <#define NULL ((void *)0)>

+
+
Interactive Editing
+

The cc command supports interactive-editing. The general syntax is: cc [command]. +

Each cc snippet is saved in a buffer which is named after the channel or nick it was used in. You can use show or diff with a buffer argument to view that buffer; otherwise you can use the copy command to copy the most recent snippet of another buffer into the current buffer and optionally chain it with another command -- for example, to copy the ##c buffer and paste it: cc copy ##c and paste. +

The commands are: copy, show, diff, paste, run, undo, s//, replace, prepend, append, and remove. Most of the commands may be chained together by separating them with whitespace or "and". +

The commands are described in more detail below: +

+
copy
+

To copy a snippet from another buffer, use the copy command. Other commands can optionally be chained after this command. +

+
 Usage: cc copy <buffer> [and ...]
+
+
show
+

To show the latest code in the buffer, use the show command. This command can take an optional buffer argument. +

+
 <pragma_> cc show
+ <PBot> pragma_: printf("Hello, world!");
+
+

This command is stand-alone and cannot be chained with other interactive-editing commands. +

+
diff
+

To see the differences between the two most recent snippets, use the diff command. This command can take an optional buffer argument. +

+
 <pragma_> cc diff
+ <PBot> pragma: printf("<replaced `Hello` with `Good-bye`>, <replaced `world` with `void`>");
+
+

This command is stand-alone and cannot be chained with other interactive-editing commands. +

+
paste
+

To paste the full source of the latest code in the buffer as the compiler sees it, use the paste command: +

+
 <pragma_> cc paste
+ <PBot> pragma_: http://some.random.paste-site.com/paste/results
+
+

This command is stand-alone and cannot be chained with other interactive-editing commands. +

+
run
+

To attempt to compile and execute the latest code in the buffer, use the run command: +

+
 <pragma_> cc run
+ <PBot> pragma_: Hello, world!
+
+

This command is stand-alone and cannot be chained with other interactive-editing commands. +

+
undo
+

To undo any changes, use undo. The undo command must be the first command before any subsequent commands. +

+
s//
+

To change the latest code in the buffer, use the s/regex/substitution/[gi] pattern. +

+
 <pragma_> cc s/Hello/Good-bye/ and s/world/void/
+ <PBot> pragma_: Good-bye, void!
+ <pragma_> cc show
+ <PBot> pragma_: printf("Good-bye, void!");
+
+
replace
+

Alternatively, you may use the replace command. The usage is (note the required single-quotes): +

+
 cc replace [all, first, second, ..., tenth, last] 'from' with 'to'
+
+
prepend
+

Text may be prepended with the prepend command: +

+
 cc prepend 'text'
+
+
append
+

Text may be appended with the append command: +

+
 cc append 'text'
+
+
remove
+

Text may be deleted with the remove command: +

+
 cc remove [all, first, second, ..., tenth, last] 'text'
+
+

C-Aphorisms

+

The C Aphorisms can be triggered with c<n> where <n> is an integer representing one of the aphorisms. For example, to quote C Aphorism 1, use `c1`. +

+
  1. The questioner's first description of the problem/question will be misleading. +
  2. All examples given by the questioner will be incomplete, misleading, broken, wrong, and/or not representative of the actual question. +
  3. The questioner will not read and apply the answers they are given but will instead continue to practice c1 and c2. +
  4. The ignorant will continually mis-educate the questioner. +
  5. When given a choice of solutions, the questioner will always choose the wrong one. +
  6. The questioner will always find a reason to say, "It doesn't work." +
  7. The questioner will paste code and say "I have a problem" or "It doesn't work" without any further information or description of the problem. +
  8. The more beginner they are, the more likely they are to be overcomplicating it. +
  9. The questioner will always have some excuse for doing it wrong. +
  10. The newbie will not accept the answer you give, no matter how right it is. +
  11. <skipped due to existing c11 factoid> +
  12. The newbie will think they are smarter than they really are. +
  13. The newbie will fail to recognize undefined behavior, and will wrongly think that their program is correct because it appears to work. +
  14. The more the questioner attempts to describe their problem, the less coherent their description becomes. +
+

Flood control

+

PBot can monitor the channel for excessive rapid traffic originating from an individual and automatically ban the offender for a certain length of time. +

+

Message flood

+

If four (4) or more messages are sent within ten (10) seconds, the flood control is triggered. The offender will be muted for 30 seconds for the first offense. Each additional offense will result in the offender being muted for a much longer period. For example, the first offense will result in 30 seconds, the 2nd offense will be 5 minutes, the 3rd will be 1 hour, and so on. +

+

Join flood

+

If four (4) or more JOINs are observed within thirty (30) minutes without any messages in between joins, the offender will be forwarded to another channel for a limited time: 2^(number_of_offenses + 2) hours. +

In addition to private instructions from PBot, this channel will have a /topic and ChanServ on-join message with instructions explaining to the offender how to remove the forwarding. The instructions are to message PBot with: unbanme <channel>. +

(Any messages sent to the public channel by the user at any time will reset their JOIN counter back to zero. The unbanme command can only be used for the first two offenses -- the offense counter is decremented once every 24 hours.) +

+

Enter key abuse

+

If four (4) consecutive messages are sent with ten (10) seconds or less between individual messages and without another person speaking, an enter-key-abuse counter is incremented. This counter will then continue to be incremented every two (2) consecutive messages with ten (10) seconds or less in between until another person speaks or more than ten (10) seconds have elapsed, whereupon it returns to requiring four (4) consecutive messages. When this counter reaches three (3) or greater, the offender will be muted using the same timeout rules as message flooding. This counter is automatically decremented once per hour. +

+

Notification message

+

PBot will send the following message to the offender each offense. +

+

Message flooding

+

"You have been muted due to flooding. Please use a web paste service such as http://codepad.org for lengthy pastes. You will be allowed to speak again in $timeout." +

+

Join flooding

+

"You have been banned from $channel due to join flooding. If your connection issues have been resolved, or this was an accident, you may request an unban at any time by responding to this message with: unbanme $channel, otherwise you will be automatically unbanned in $timeout." +

+

Enter key abuse

+

"You have been muted due to abusing the enter key. Please do not split your sentences over multiple messages. You will be allowed to speak again in $timeout." +

+

Opping/Deopping

+

ChanServ will automagically op and deop PBot when necessary. PBot will wait until about 5 minutes have elapsed before requesting a deop from ChanServ. +
