- Step 2: Read on
General
- thou shalt not violate causality in our time cone, or else
Docstrings
Docstrings should ONLY use triple-double-quotes
(""")
Single-line docstrings should NEVER have extraneous whitespace between enclosing triple-double-quotes.
Deviation! Sentence fragments do not have punctuation. Specifically in the command classes the one line docstring is also the help string for that command and those do not have periods.
"""A one line docstring looks like this"""
Calling Methods
Deviation! When breaking up method calls due to the 79 char line length limit, use the alternate 4 space indent. With the first argument on the succeeding line all arguments will then be vertically aligned. Use the same convention used with other data structure literals and terminate the method call with the last argument line ending with a comma and the closing paren on its own line indented to the starting line level.

Text encoding
Note: this section clearly has not been implemented in this project yet, it is the intention to do so.
All text within python code should be of type 'unicode'.
WRONG:
>>> s = 'foo' >>> s 'foo' >>> type(s) <type 'str'>
RIGHT:
>>> u = u'foo' >>> u u'foo' >>> type(u) <type 'unicode'>
Transitions between internal unicode and external strings should always be immediately and explicitly encoded or decoded.
All external text that is not explicitly encoded (database storage, commandline arguments, etc.) should be presumed to be encoded as utf-8.
WRONG:
infile = open('testfile', 'r') mystring = infile.readline() myreturnstring = do_some_magic_with(mystring) outfile.write(myreturnstring)
RIGHT:
infile = open('testfile', 'r') mystring = infile.readline() mytext = mystring.decode('utf-8') returntext = do_some_magic_with(mytext) returnstring = returntext.encode('utf-8') outfile.write(returnstring)
