# Small Deflate
`sdefl` is a small bare bone lossless compression library in ANSI C (ISO C90)
which implements the Deflate (RFC 1951) compressed data format specification standard.
It is mainly tuned to get as much speed and compression ratio from as little code
as needed to keep the implementation as concise as possible.
## Features
- Portable single header and source file duo written in ANSI C (ISO C90)
- Dual license with either MIT or public domain
- Small implementation
- Deflate: 525 LoC
- Inflate: 320 LoC
- Webassembly:
- Deflate ~3.7 KB (~2.2KB compressed)
- Inflate ~3.6 KB (~2.2KB compressed)
## Usage:
This file behaves differently depending on what symbols you define
before including it.
Header-File mode:
If you do not define `SDEFL_IMPLEMENTATION` before including this file, it
will operate in header only mode. In this mode it declares all used structs
and the API of the library without including the implementation of the library.
Implementation mode:
If you define `SDEFL_IMPLEMENTATION` before including this file, it will
compile the implementation . Make sure that you only include
this file implementation in *one* C or C++ file to prevent collisions.

# Small Deflate
`sdefl` is a small bare bone lossless compression library in ANSI C (ISO C90)
which implements the Deflate (RFC 1951) compressed data format specification standard.
It is mainly tuned to get as much speed and compression ratio from as little code
as needed to keep the implementation as concise as possible.
## Features
- Portable single header and source file duo written in ANSI C (ISO C90)
- Dual license with either MIT or public domain
- Small implementation
- Deflate: 525 LoC
- Inflate: 320 LoC
- Webassembly:
- Deflate ~3.7 KB (~2.2KB compressed)
- Inflate ~3.6 KB (~2.2KB compressed)
## Usage:
This file behaves differently depending on what symbols you define
before including it.
Header-File mode:
If you do not define `SINFL_IMPLEMENTATION` before including this file, it
will operate in header only mode. In this mode it declares all used structs
and the API of the library without including the implementation of the library.
Implementation mode:
If you define `SINFL_IMPLEMENTATION` before including this file, it will
compile the implementation. Make sure that you only include
this file implementation in *one* C or C++ file to prevent collisions.
