# Other single-file public-domain/open source libraries with minimal dependencies

In addition to all of [my libraries](https://github.com/nothings/stb), there are other, similar libraries.

People have told me about quite a few of these. However, I haven't used most of these libraries
and can't comment on their quality. (If you use them and aren't their author, feel
free to tell me about their quality.) _Newest additions are in italics._

There is also these XML libraries, but if you're using XML, shame on you:

- **parsing** [tinyxml2](https://github.com/leethomason/tinyxml2): XML (zlib license)
- **parsing** [pugixml](http://pugixml.org/): XML (MIT license)

There are some libraries that are just _so_ awesome that even though they use more
than two files we're going to give them special dispensation to appear in their own
little list here. If you're a crazy purist, be warned, but otherwise, enjoy!

- **user interface** [ImGui](https://github.com/ocornut/imgui): an immediate-mode GUI ("imgui") named "ImGui" (MIT license)

Also you might be interested in other related, but different lists:

- [clib](https://github.com/clibs/clib/wiki/Packages): list of (mostly) small single C functions (licenses not listed)

## *List FAQ*

### Can I link directly to this list?

Yes, you can just use this page. If you want a shorter, more readable link, you can use [this URL](https://github.com/nothings/stb#other_libs) to link to the FAQ question that links to this page.

### Why isn't library XXX which is made of 3 or more files on this list?

I draw the line arbitrarily at 2 files at most. (Note that some libraries that appear to
be two files require a separate LICENSE file, which made me leave them out). Some of these
libraries are still easy to drop into your project and build, so you might still be ok with them.
But since people come to stb for single-file public domain libraries, I feel that starts
to get too far from what we do here.

### Why isn't library XXX which is at most two files and has minimal other dependencies on this list?

Probably because I don't know about it, feel free to submit a pull request, issue, email, or tweet it at
me (it can be your own library or somebody else's). But I might not include it for various
other reasons, including subtleties of what is 'minimal other dependencies' and subtleties
about what is 'lightweight'.

### Why isn't SQLite's amalgamated build on this list?

Come on.
