Advanced Argument Parser for WikiMacros

Description

This plug-in provides an advanced version of the parse_args function for WikiMacros.

This function is used in WikiMacros to parse the macro arguments. This enhanced version is meant as a replacement of trac.wiki.macros.parse_args and supports several advanced options (see section #Parameters). The most important feature is the support for quoting the delimiter, e.g. 'key1=val1,key2="some,text",key3=val3' will correctly return 'some,text' as the value of key2. The original parse_args function would return '"some' and handle 'text"' as separate argument.

Documentation

Definition

def parse_args (args, strict = True, multi = False, listonly = False, minlen = 0,
        quotechar = '"', escchar = '\\', delim = ',', delquotes = False)

Usage Example

# Instead of: from trac.wiki.macros import parse_args
# Use:
from tracadvparseargs import *


class SomeMacro(WikiMacroBase):
    def expand_macro(self, formatter, name, args):
        largs, kwargs = parse_args( args, <options> )

Parameters

args

The argument string; 'content' in `expand_macro. This is the only mandatory argument.

strict

Enables strict checking of keys.

multi

Enables folding of muliple given keys into list.
If set to True, values of multiple given keys will be returned as list, but single given keys will return a scalar.
If set to a list, only the values of the listed keys will be returned as list, but always as list even when there is only one value.
If this list contains '*', all values are always returned as list.

listonly

If true only a list is returned, no directionary.

minlen

Extend returned list to given minimum length. Only used when listonly=True.

Parser parameters

quotechar

The quote character to be used.

escchar

The escape character to be used.
