Read PEP 8 (Guido's Style Guide) and know that we use almost all the
|
|
same style guidelines.
|
|
|
|
Maximum line length is 79 characters. 78 is a safer bet, though.
|
|
|
|
Identation is 4 spaces per level. No tabs.
|
|
|
|
Single quotes are used for all string literals that aren't docstrings.
|
|
They're just easier to type.
|
|
|
|
Triple double quotes (""") are always used for docstrings.
|
|
|
|
Spaces go around all operators (except around '=' in default arguments
|
|
to functions) and after all commas (unless doing so keeps a line
|
|
within the 79 character limit).
|
|
|
|
Class names are StudlyCaps. Method and function names are camelCaps
|
|
(StudlyCaps with an initial lowercase letter). If variable and
|
|
attribute names can maintain readability without being camelCaps, then
|
|
they should be entirely in lowercase, otherwise they should also use
|
|
camelCaps. Plugin names are StudlyCaps.
|
|
|
|
Imports should always happen at the top of the module, one import per
|
|
line (so if imports need to be added or removed later, it can be done
|
|
easily).
|
|
|
|
A blank line should be between all consecutive method declarations in
|
|
a class definition. Two blank lines should be between all consecutive
|
|
class definitions in a file. Comments are even better than blank
|
|
lines for separating classes.
|
|
|
|
Database filenames should generally begin with the name of the plugin
|
|
and the extension should be 'db'. baseplugin.DBHandler does this
|
|
already.
|
|
|
|
Whenever creating a file descriptor or socket, keep a reference around
|
|
and be sure to close it. There should be no code like this:
|
|
s = urllib2.urlopen('url').read()
|
|
Instead, do this:
|
|
fd = urllib2.urlopen('url')
|
|
s = fd.read()
|
|
fd.close()
|
|
This is to be sure the bot doesn't leak file descriptors.
|
|
|
|
All plugins should include a docstring decsribing what the plugin
|
|
does. This docstring will be returned when the user wants help on a
|
|
plugin.
|
|
|
|
Method docstrings in classes deriving from callbacks.Privmsg should
|
|
include an argument list as their first line, and after that a blank
|
|
line followed by a longer description of what the command does. The
|
|
argument list is used by the 'syntax' command, and the longer
|
|
description is used by the 'help' command.
|
|
|
|
Whenever joining more than two strings, use string interpolation, not
|
|
addition:
|
|
s = x + y + z # Bad.
|
|
s = '%s%s%s' % (x, y, z) # Good.
|
|
s = ''.join([x, y, z]) # Best, but not as general.
|
|
This has to do with efficiency; the intermediate string x+y is made
|
|
(and thus copied) before x+y+z is made, so it's less efficient.
|
|
|
|
When writing strings that have formatting characters in them, don't
|
|
use anything but %s unless you absolutely must. In particular, %d
|
|
should never be used, it's less general than %s and serves no useful
|
|
purpose.
|
|
|
|
Use the log module to its fullest; when you need to print some values
|
|
to debug, use self.log.debug to do so, and leave those print
|
|
statements in the code (commented out) so they can later be
|
|
re-enabled. Remember that once code is buggy, it tends to have more
|
|
bugs, and you'll probably need those print statements again.
|
|
|
|
SQL table names should be all-lowercase and include underscores to
|
|
separate words. This is because SQL itself is case-insensitive.
|
|
|
|
SQL statements in code should put SQL words in ALL CAPS:
|
|
SELECT quote FROM quotes ORDER BY random() LIMIT 1
|
|
|
|
All plugins should have test cases written for them. Even if it
|
|
doesn't actually test anything but just exists, it's good to have the
|
|
test there so there's a place to add more tests later (and so we can
|
|
be sure that all plugins are adequately documented.
|
|
|
|
All uses of eval() that expect to get integrated in Supybot must be
|
|
approved by jemfinch, no exceptions.
