MD-TUI is a TUI application for viewing markdown files directly in your
terminal. I created it because I wasn't happy with how alternatives handled
links in their applications. While the full markdown specification is not yet
supported, it will slowly get there. It's a good solution for quickly viewing
your markdown notes, or opening external links from someones README. If your
terminal support images, they will render.
Using cargo: cargo install md-tui --locked
On Arch Linux: pacman -S md-tui
For Nix users, there's also Nix flake.
Prebuilt binaries with install script can be found on the release page.
Start the program running mdt <file.md> or just mdt. The latter will search
recursively from where it was invoked for any markdown file and show it in a
file tree.
These are the default settings. See keyboard configuration for configuration options.

MD-TUI supports syntax highlighting in code blocks for the following
languages:
The program checks for the file ~/.config/mdt/config.toml at startup. The
following parameters and their defaults are written below.
Some key actions are not configurable. Like the following:
If you override another default key, it's undefined behavior if that key does not get reassigned.
Actions can only be assigned to single characters. Space, fn keys, ctrl+key, backspace etc., will not take effect and the default will be in use.

type of links.
This application also exists as a plugin for Neovim called Preview.
[!NOTE]
This version does not support images regardless of your terminal capabilities.
Both PRs and issues are appreciated!
It's possible to use this as a library. It's not well documented for that use, but the feature is there. There is one default feature attached, which is the whole highlighting of code blocks.
