|
||||||
- [md4c](https://github.com/mity/md4c) for markdown parsing
|
|
||||||
- [ansi-term](https://github.com/ziglibs/ansi-term) wraps ansi styling
|
|
||||||
- [zig-clap](https://github.com/Hejsil/zig-clap) for arg parsing

|
||||||
## building
|
|
||||||
1. install [zig 0.13.0](https://ziglang.org/download/#release-0.13.0)
|
|
||||||
2. clone repo
|
|
||||||
3. run `zig build`
|
|
||||||
|
|
||||||
if you want a release build:
|
|
||||||
|
|
||||||
4. run `zig build --release=small`
|
|
||||||
|
|
||||||
release optimize modes are:
|
|
||||||
|
|
||||||
- fast
|
|
||||||
- safe
|
|
||||||
- small
|
|
||||||
|
|
||||||
the mdcat binary will be in `zig-out/bin/mdcat`
