indeed, there are quite a number of more or less unambiguously specified
configuration file formats.
for the lack of an existing solution (or, more likely, due to my
ignorance) i've crufted together a trivial script that parses simple
ini-like config files, with square-bracketed section headers, like this:
[foo]
bar = BAR
[bar]
foo = ...
you just source the script, specify the config file, and get a nested
list of config parameters, e.g.
source('http://miscell.googlecode.com/svn/rconfig/rconfig.r')
config = rconfig('somefile.cfg')
config$foo$bar
# "BAR"
the functionality is rudimentary and not fool-proof, no string-to-number
parsing, no comment skipping, etc. i'm not really suggesting it as a
solution to your (underspecified) problem, feel free to modify/extend it
to match your needs.
