Fancy cat
for Markdown (that is, CommonMark):
$ mdcat sample.md
mdcat in WezTerm, with "One Light (base16)", "Gruvbox Light", and "Darcula (base16)" (from left to right), and JetBrains Mono as font.
mdcat
works best with iTerm2, WezTerm, and kitty, and a good terminal font with italic characters.
Then it
- nicely renders all basic CommonMark syntax,
- highlights code blocks with syntect,
- shows links, and also images inline in supported terminals (see above, where "Rust" is a clickable link!),
- adds jump marks for headings in iTerm2 (jump forwards and backwards with ⇧⌘↓ and ⇧⌘↑).
Terminal | Basic syntax | Syntax highlighting | Images | Jump marks |
---|---|---|---|---|
Basic ANSI¹ | ✓ | ✓ | ||
Windows 10 console | ✓ | ✓ | ||
Terminology | ✓ | ✓ | ✓ | |
iTerm2 | ✓ | ✓ | ✓² | ✓ |
kitty | ✓ | ✓ | ✓² | |
WezTerm | ✓ | ✓ | ✓² | |
VSCode | ✓ | ✓ | ✓² | |
Ghostty | ✓ | ✓ | ✓² |
- mdcat requires that the terminal supports strikethrough formatting and inline links. This includes most modern terminal emulators, such as Windows Terminal, KDE Konsole, or anything based on VTE, GNOME's terminal emulation library. But mdcat likely won't work well on old terminals that lack these features (e.g. the Linux text console).
- SVG images are rendered with resvg, see SVG support.
Not supported:
- CommonMark extension for footnotes.
- Inline markup and text wrapping in table cells.
Try mdcat --help
or read the mdcat(1) manpage.
- Release binaries built on Github Actions.
- These binaries are build from Git source on Github actions; you find provenance attestations at https://github.com/swsnr/mdcat/attestations.
- 3rd party packages at Repology
- You can also build
mdcat
manually withcargo install mdcat
(see below for details).
mdcat
can be linked or copied to mdless
; if invoked as mdless
it automatically uses pagination.
Run cargo build --release
.
Building requires libcurl
.
When packaging mdcat
you may wish to include the following additional artifacts:
-
A symlink or hardlink from
mdless
tomdcat
(see above). -
Shell completions for relevant shells, by invoking
mdcat --completions
after building, e.g.$ mdcat --completions fish > /usr/share/fish/vendor_completions.d/mdcat.fish $ mdcat --completions bash > /usr/share/bash-completion/completions/mdcat $ mdcat --completions zsh > /usr/share/zsh/site-functions/_mdcat # Same for mdless if you include it $ mdless --completions fish > /usr/share/fish/vendor_completions.d/mdless.fish $ mdless --completions bash > /usr/share/bash-completion/completions/mdless $ mdless --completions zsh > /usr/share/zsh/site-functions/_mdless
-
A build of the man page
mdcat.1.adoc
, using AsciiDoctor:$ asciidoctor -b manpage -a reproducible -o /usr/share/man/man1/mdcat.1 mdcat.1.adoc $ gzip /usr/share/man/man1/mdcat.1 # If you include a mdless as above, you may also want to support man mdless $ ln -s mdcat.1.gz /usr/share/man/man1/mdless.1.gz
mdcat
can output extensive tracing information when asked to.
Run mdcat
with $MDCAT_LOG=trace
for complete tracing information, or with $MDCAT_LOG=mdcat::render=trace
to trace only rendering.
