Comment (by hinder):

 Replying to [comment:7 eschnett]:
 > Thorn Formaline's design goal is to store sufficient information about
 simulations to make them reproducible. Most people know that it stores the
 complete source code by default. It also stores all parameter values, as
 well as regular updates if parameters ares steered. It uses a simple
 "KEY=VALUE" format for this, but can also generate several other formats
 (XML, or submit to a web server in real-time so that simulation progress
 can be more easily observed).

 I propose that you use the "ini" file format.  It is easy to parse this in
 Python, and hence from a shell script:

 {{{
 #!/bin/bash

 function read-key()
 {
     python -c "import ConfigParser; import sys; config =
 ConfigParser.ConfigParser(); config.read(sys.argv[1]); print
 config.get(sys.argv[2],sys.argv[3])" "$1" "$2" "$3"
 }

 function read-sections()
 {
     python -c "import ConfigParser; import sys; config =
 ConfigParser.ConfigParser(); config.read(sys.argv[1])
 for s in config.sections():
   print s" "$1"
 }

 read_sections "file.ini"
 read_key "file.ini" "sectionname" "keyname"

 }}}

 It is a (relatively) standard format, and there should be similar
 libraries for whatever analysis framework one might be using.  We might
 have to tweak things like quoting and multi-element values to work with
 different readers, but I think this is still preferable to using a new
 format.
