casualx / ini_core Goto Github PK

Hi,

I'm in need of a round tripping (i.e. not reformatting on save) INI-parser to be able to semantically patch arbitrary INI-files. This library looks like the closest existing one to my needs for Rust (if I keep the auto trim turned off). However it does have some limitations that I'm wondering if you are interested in addressing / accepting patches from me to address (or if I should just take this project as a basis/inspiration to make my own thing):

• Non-UTF-8: I don't know the encoding of the files I will be working with. Probably UTF-8 almost always, but that is not something I can assume in general. An alternative [u8] API would be more suitable for me.
• I don't know the comment symbol in the file in advance (I would like to accept both # and ; at least). Supporting a set of comment symbols would be something I need.
• Support for dealing with "strange" non-standard INI data. Since I'm dealing with arbitrary INI files from arbitrary programs, here are some of the weirdness I have seen and need to do something sensible on:
  • Key & values before the first section
  • "Silly" sections like [section][subsection][3] or [section[32]]
  • Weird keys like AnimationSpeed[$d] (This one is from a KDE ini file)
• As I said, I need to be able to round trip things without reformatting, so whitespace must be preserved regardless of position. This includes telling key = value apart from key=value (currently already supported), as well as dealing with trailing whitespaces and blank lines (not sure if this is preserved currently?). From what I can tell, this library with auto-trim turned off is most of the way there, though I have not yet tested it fully.

The reason I need this is that I'm planning on rewriting this project in Rust (instead of Python) for performance reasons. In that case I had to roll my own ini parser, as Python didn't have what I needed either.
