# inih (INI Not Invented Here)
|
||||
|
||||
**inih (INI Not Invented Here)** is a simple [.INI
|
||||
file](http://en.wikipedia.org/wiki/INI_file) parser written in C. It's only a
|
||||
couple of pages of code, and it was designed to be _small and simple_, so it's
|
||||
good for embedded systems. It's also more or less compatible with Python's
|
||||
[ConfigParser](http://docs.python.org/library/configparser.html) style of .INI
|
||||
files, including RFC 822-style multi-line syntax and `name: value` entries.
|
||||
|
||||
The original project can be found [here](https://github.com/benhoyt/inih). I
|
||||
have included the sources in this repository because it is not packaged for all
|
||||
platforms (notably macOS), and the version here supercedes the version that is
|
||||
distributed in most "stable" Linux distributions such as Debian.
