# mdcat
[][crates]
[][license]
[][travis]
[](https://dependabot.com)
`cat` for Markdown (that is, [CommonMark][]):
```
$ mdcat sample.md
```
![mdcat showcase with different colour themes][sxs]
mdcat in [iTerm2], with [Dracula], and [Solarized] Light and Dark (from left to
right), and [PragmataPro] as font.

## Features
`mdcat` works best with [iTerm2] or a compatible terminal emulator, and a good
terminal font with italic characters. Then it
* nicely renders all basic CommonMark syntax (no [tables][GH-2] or [footnotes][GH-1] though),
* highlights code blocks with [syntect],
* shows [links][osc8] and images inline in supported terminals (see above, where "Pixabay" is a clickable link!),
* adds jump marks for headings in [iTerm2] (jump forwards and backwards with
<key>⇧⌘↓</key> and <key>⇧⌘↑</key>).
| Terminal | Basic syntax | Syntax highlighting | Links | Images | Jump marks |
| :---------------------- | :-----------: | :-----------------: | :---: | :----: | :--------: |
| Basic ANSI | ✓ | ✓ | | | |
| Windows [ConEmu][]¹ | ✓ | ✓ | | | |
| Windows 10 console¹ | ✓ | ✓ | | | |
| VTE 0.50 or newer based | ✓ | ✓ | ✓ | | |
| [Terminology][] | ✓ | ✓ | ✓ | ✓ | |
| [iTerm2][] | ✓ | ✓ | ✓ | ✓ | ✓ |
1: On Windows you need to install with `--no-default-features` (see below).
Not supported:
* CommonMark extensions: [Footnotes][GH-1] and [tables][GH-2]
* [Re-filling paragraphs][GH-4]

## Installation
### Binaries
The [Releases] page provides pre-build binaries for Linux, macOS and Windows.
Use these binaries to try `mdcat`, particularly on Windows.
[Releases]: https://github.com/lunaryorn/mdcat/releases
### 3rd party packages
Some package managers include `mdcat`:
* [Homebrew]: `brew install mdcat`
* Arch Linux: [mdcat in AUR][aur]
* Void Linux: `xbps-install -S mdcat`
* OpenBSD: [port][epbsd_port] via [EPBSD][epbsd]
While these packages may not always be up to date we generally recommend to use
these to keep `mdcat` updated with the rest of the system.
[Homebrew]: https://brew.sh
[aur]: https://aur.archlinux.org/packages/mdcat/
[epbsd]: https://epbsd.org/
[epbsd_port]: https://gitlab.com/epbsd/ports/tree/master/textproc/mdcat
### Building with rustup
You can also build `mdcat` manually with `cargo`. Install Rust via [rustup] and
run `cargo install mdcat`. To keep mdcat up to date install [cargo-update] and
run `cargo install-update mdcat`.
**Note:** On Windows you likely need `--no-default-features` to make `mdcat`
build.
[rustup]: https://www.rustup.rs
[cargo-update]: https://github.com/nabijaczleweli/cargo-update
### SVG support
`mdcat` needs `rsvg-convert` to show SVG images in [iTerm2]; otherwise `mdcat`
only shows the image title and URL for SVG images. Install with `brew install
librsvg`.
[Terminology] supports SVG out of the box and needs no additional tools.
### Future plans
- [ ] Figure out a better way to show HTML [GH-3].
- [ ] CommonMark extensions: Footnotes [GH-1].
- [ ] CommonMark extensions: Tables [GH-2].
- [ ] Ignore soft wraps and wrap inline text a column limit instead [GH-4].
