marquee-markdown

TUI markdown reader that renders documents like Claude artifacts

Install Source on GitHub →

The reader in motion: the contents pane tracking the scroll, a section folding and unfolding, a search narrowing as it is typed, and the theme picker previewing against the document behind it

Ten themes
Eight ports of established colorschemes
Rust 1.88 or newer
Linux, macOS, Windows

Install

cargobinstallHomebrew

cargo install marquee-markdown

cargo binstall marquee-markdown

brew install SophanaSok/marquee/marquee-markdown

Also on Scoop, Nix, and the release page as prebuilt binaries, .deb and .rpm packages.

What it does

Reads markdown properly. Headings become typography rather than hash marks, code blocks become sealed cards, tables get box drawing, and GFM callouts get an icon and a hue.
Reads the HTML in a README too. A centered <h1> becomes a heading in the contents pane, badge images become the links they advertise, <br> breaks a line, a <details> block is shown open with its <summary> as the title, and an HTML <ul> or <table> — spans, sections, captions and all — is drawn by the same emitter its markdown spelling is, instead of the tags themselves reaching the page.
Math is notation, not punctuation. $E = mc^2$ reads as a code span rather than as a formula wearing its dollar signs. TeX is not typeset — there is no glyph budget for that in a cell grid — but the delimiters go.
A contents pane that tracks where you are, with folding — the thing glow has no equivalent of, and the reason this exists.
Ten themes, or your own, or your terminal’s own colors.
Search inside a document with /, n and N, highlighted in place.
A file browser that streams as it walks, with a fuzzy filter.
Reads what you point it at: a file, a directory, standard input, a URL, or github.com/owner/repo.
Reloads when you save, and e opens your editor at the line on screen.
Everything is configurable and every key is rebindable, from one TOML file.
Themes are data, so a new palette needs no Rust and no recompile.

A real terminal, not a mock-up

# Marquee

A terminal markdown reader that renders documents the way Claude artifacts do.

> [!NOTE]
> Callouts get an icon, a title, and a hue of their own.

## Rendering

Code blocks are sealed containers — a long line wraps *inside* the card
rather than escaping it:

```rust
fn width(text: &str) -> usize {
    text.graphemes(true).map(grapheme_width).sum()
}
```

## Tables

| Construct | Rendered as |
| --- | --- |
| Heading | weight, colour, rhythm |
| Quote | an accent gutter bar |
| Rule | a hairline across the column |

## Navigation

- The contents pane tracks where you are reading
- `/` searches, `n` and `N` step through the hits
- `]` and `[` step through links
