Someone asked me what they thought was a good language for parsing KeyValues for some standalone application. The #1 factor that came to mind was "Does a parser exist for that language?"

Turns out it's harder to find parsers than I thought. I wanted to collect the results of my search in one place, so here goes:

Note: I haven't used or reviewed most of these personally
C++ Valve KeyValues Implementation: KeyValues.h KeyValues.cpp - LOW portability (Requires lots of hl2sdk by default)
C++ SM TextParsers Implementation: TextParsers.h TextParsers.cpp - MEDIUM portability (Linked version is psychonic's GDC fork port)
Node/Javascript: keyvalues-node - Should be portable, but their output format is questionable.
PHP: SourceBans KeyValues/SMC_Parser implementation
PHP: KVReader2.php another PHP implementation that doesn't use token_get_all
C#: SteamKit implementation
Python: py-keyvalues

Those are my finds thus far. I was hoping for a Python implementation personally, but I couldn't find one. Also: If anyone can give me formatted links for the bitbucket/sm repos that give latest version instead of revisioned version that would be helpful I think.

Edit: Got python, fixed repo links.

Just replace the revision hash with "tip".

Valve has an updated version of their KeyValues parser in the Source SDK 2013: KeyValues.h KeyValues.cpp

SMC is a distinct format with different syntax rules from KV.

I have a python parser that I'm working on. (it works perfectly but looks ugly as sin right now)

Cool thanks.

Cool thanks.

True, but there's enough overlap that certain files may be valid in both formats, no?

Awesome, would love to be able to use it

[necavi]

Here it is in its current form: https://github.com/necavi/py-keyvalues

I'm working on changing it quite a bit, but for now this'll work (and thanks to python being awesome I can keep most of the syntax the same when I change it).

Here's another PHP one which doesn't use token_get_all (which doesn't appear to work with some php versions): https://github.com/nikkiii/kvreader/.../kvreader2.php

It parses admins.cfg (Which I believe is SMC) and standard items_game.txt, tf_english.txt (language file) etc just fine, however it won't write correctly with multiple sections which have the same keys.

is there one for brainfuck? i could use it

My attempt at a python KV parser, doesn't support comments or #include stuff for KV though, I kinda wrote it for Source-Python, but it works independently anyway and is Python 3 (note: self-singed cert on the svn ) https://svn.german-slaughterhouse.de...s/keyvalues.py
