# librune — easy Unicode in a post-ASCII world
Librune is a C library that aims to make interacting with Unicode and
UTF-8 easy in C. There are no plans at the moment to support UTF-16 or
-32, but they may be supported if such a usecase ever comes up.
This library requires C23.
## Terminology
This library uses the term ‘rune’ to refer to a single Unicode-codepoint,
and defines a `rune` datatype which is an unsigned integer type which
represents a rune (shocker).
## Headers
This library contains the following headers:
- `builder.h` — string building functions
- `gbrk.h` — grapheme-iteration functions
- `rtype.h` — rune categorization à la `ctype.h`
- `rune.h` — rune-constants, -macros, and -functions
- `utf8.h` — UTF-8 encoding, decoding, iteration, etc.
## Compilation
This library comes with a build script in the form of `make.c`. To build
the library all you need is a C compiler. The build script will build a
static library called ‘librune.a’.
```sh
# Make sure to link with pthread
cc -lpthread -o make make.c
./make
```
If you want to build the library in release-mode (optimizations enabled),
simply pass the `-r` flag to the build script:
```sh
./make -r
```
You can also pass the `-l` flag to enable link-time optimizations:
```sh
./make -lr
```
## Installation
There is no ‘intended’ way in which this library should be installed,
used, and distributed. This library is primarily written for myself, and
I prefer to vendor it in my projects. You may choose to install it as a
shared and/or static library. You’re an engineer aren’t you? Figure it
out.
