This parser aims to be the smallest possible while supporting a sufficient subset of the INI format.
The parser is meant for use in embedded applications.
When compiled for a bare metal Cortex-M0, **the whole parser fits in 336 bytes** of Flash and 30 (+buffers) bytes of RAM.
## Features
- Basic INI format support
- Accepts both Unix and DOS newlines
- Minimal memory footprint
- The input file can be loaded in multiple pieces of any size.
- Buffer sizes (section, key, value) can be configured in the header file.
- Custom data `void *` for maintaining user context, passed to the callback
## Sypported syntax
Any whitespace, except inside a value, is discarded.
- **Sections** - `[section]`
- Supports any characters except whitespace and `]`
- **Key-value pairs** - `key = value`
- Key supports any characters except whitespace and `=`

- Value can contain whitespace, leading and trailing whitespace is removed.
- Ends with either `\r` or `\n`
- **Comment** `# comment ...`
- Ends with either `\r` or `\n`
## Limitations
- Not re-entrant, uses a static state variable
- No checks for invalid syntax
- Whitespace inside keys and section names is removed
- Quoted strings and escape sequences are not supported, will be collected as plain text
- Value can't be followed by an inline comment
See the file `test.c` for an example of the most basic usage; see the header file for more details on the API.
