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 'help' command, and the longer description is used by the 'morehelp'
|
|
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.
|
|
|
|
Use the debug module to its fullest; when you need to print some values to
|
|
debug, use debug.printf to do so, and leave those print statements in the code
|
|
(perhaps 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 subclasses
|
|
test.PluginDocumentation, 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).
