wr

README

wr

A reader and browser for your terminal. wr fetches a page, extracts the article and opens it in an animated reader built with Bubble Tea: properly formatted Markdown (real headings, bold, lists, tables — no # or ** in sight), per-language syntax highlighting, and a full browsing experience — click links, go back and forward, an address bar that also searches the web, history, bookmarks. Everything is customizable from inside the program. The colors come from your terminal's own 16-color ANSI palette — one accent plus its partner, and the shades picked for your background — so it follows your theme (gruvbox, nord, …) with zero configuration.

wr https://example.com/some-article
wr rust async book          # not an address? it is searched on the web
wr                          # the start page: your bookmarks and recent pages

What you get

Reading

• Formatted Markdown. Headings with a mark and a rule, bold, italic, inline code, nested lists, quotes, tables, strikethrough and task lists, with the Markdown syntax gone.
• Code with color. Highlighted per language (chroma) inside a labeled frame. The language is read from data-language or language-xx classes.
• Search as you type (/), smart-case, highlighted matches, n / N to jump between them. Section index (t) and heading-to-heading jumps.
• Select and copy. Drag to select; it is copied when you let go. Double click selects a word, triple click a line. Code blocks copy without their frame and margin, and paragraphs wrapped on screen come out as the single line they were written as.

Browsing

• Links are clickable. Click one, or press Tab / Shift+Tab to focus links (the footer shows where it goes) and Enter to open. Or press f and every link on screen gets a short label: type it to follow that link, no mouse needed.
• Back and forward (H / L, Backspace, Alt+←/→, or your mouse's back and forward buttons). Going back returns you to the exact spot you left, and it is instant because pages are cached.
• An address bar (o). Type an address, a local file, or plain words: words search the web (DuckDuckGo by default; Wikipedia, GitHub or your own engine are one setting away). It suggests your bookmarks and history as you type.
• History (v) and bookmarks (', toggle the current page with *). Filter by typing, open with Enter, remove with Ctrl+D. A star in the footer shows a bookmarked page.
• A start page (~, or just run wr) listing your bookmarks and recent pages as links. Make any page your homepage from Settings.
• In-page links (#section) jump to the matching heading. Search-engine redirect links go straight to the real target.
• More than HTML. Markdown files and READMEs render as Markdown, plain text and JSON appear in a code block, and local files work (wr notes.md). Things it cannot show (images, PDFs) say so, and x opens the page in your real browser.
• Failures are safe. A page that fails to load never replaces the one you are reading, and a slow load can be overtaken by a newer one.

Make it yours

Everything below is changed from the menu, live, and saved for you:

• Settings (, or menu → Settings): about 30 options in groups — layout (width, centering, spacing, heading rules, code frames, links mode, braille, accent color), footer and scrollbar (each part separately, including turning the footer off), mouse, every animation separately plus scroll speed, search engine, homepage, history, cache. ←/→ change a value, d restores its default, and the selected option's help is shown underneath.
• Keyboard shortcuts (menu → Keyboard shortcuts): rebind any key. Select an action, press Enter, press the new key. a adds another key to an action, x unbinds, d restores the defaults. The footer hints follow your bindings.
• Prefer a file? It is ~/.config/wr/config.toml, fully commented. Both ways edit the same file.

Motion

Built on Charm's harmonica spring physics, and designed to cost nothing at rest:

• Spring scrolling. Every jump (G, ], a search hit, a link, the mouse wheel) glides with a critically damped spring: no bounce. A one-line step lands in about 60 ms and a 300-line jump in about 330 ms. The Braille scrollbar and progress bar follow the fractional position, so they move smoothly too.
• Page reveal, shutter panels, a braille loading wave and quick notices that type themselves out and vanish when you press a key.
• Zero idle cost. Frames are only scheduled while something is moving.

Each animation has its own switch, and animations = false makes everything instant.

The reader on video: media/*.tape are VHS tapes and scripts/capture.sh regenerates the recorded frames on the docs site — see media/README.md.

Why it exists

I wanted to read documentation and technical articles without leaving the terminal and without losing the highlighted code. What I tried first did not do it:

Tool	What happened
w3m / lynx	They render the HTML, but code stays plain: they ignore style and <font color>.
trafilatura --markdown	Good extraction, but it drops the language of code blocks (bare ```), leaving nothing to highlight with.
bat -l markdown	Colors the Markdown, but not the code inside fences.

wr glues the pieces together and keeps the key piece of data: each block's language.

Install

The quick way (Linux and macOS, no Go needed): download the right binary from the latest release, verify it and put it in ~/.local/bin:

curl -fsSL https://raw.githubusercontent.com/sazardev/wr/main/install.sh | sh

(INSTALL_DIR=/usr/local/bin to choose where, WR_VERSION=v0.1.0 to pick a version. The script checks the SHA-256 checksum before installing. Read it first if you like: install.sh.)

Or by hand: download wr_<os>_<arch>.tar.gz for your system from the releases page (linux or darwin, amd64 or arm64), check it against checksums.txt, and unpack the wr binary anywhere on your PATH.

With Go 1.26 or newer:

go install github.com/sazardev/wr@latest

From source:

git clone https://github.com/sazardev/wr.git
cd wr
go build -ldflags="-s -w" -o ~/.local/bin/wr .

Release binaries are static (no libc needed) and about 14 MB (chroma bundles all its lexers). Tested on Linux (WSL2, CachyOS) with Alacritty and Go 1.27; the macOS and arm64 builds are cross-compiled and have not been run by me. Windows: use WSL.

New to wr? Read the guide (also on the docs site, one page per section, with six palettes — the design system describes them): how to follow links, go back and forward, search the web, use history and bookmarks, select and copy, and make it yours.

Braille needs a font with those glyphs (most modern monospace fonts have them, e.g. Nerd Fonts). If yours does not, turn off Braille decoration in Settings.

Usage

wr                 # the start page
wr URL             # open an address
wr some words      # anything that is not an address or a file is searched
wr notes.md        # a local file
wr -L URL          # links hidden for this session
wr --md URL        # print the Markdown as is, for pipes (always fetches fresh)
wr --fresh URL     # ignore the cache and download again
wr --clear-cache   # delete the cache
wr --config        # create (if missing) and print the config file path
wr --version       # print the version

When the output is not a terminal (wr URL | less -R) it prints the rendered document and exits, with no interface.

Shortcuts

These are the defaults; every one can be rebound.

Key	Action
o	open an address or search the web
H L / Backspace	back / forward
Tab Shift+Tab	focus the next / previous link; Enter opens it
f	label the links on screen, type a label to follow it
v / ' / *	history / bookmarks / bookmark this page
~	the start page
x	open this page in your browser
j k / ↓ ↑	one line
space b	page down / up
d u	half page
g G	top / bottom
] [	next / previous section
t	section index
/	search in the page (enter accepts, esc cancels and returns where you were)
n N	next / previous match
r	reload (or apply the newer version already downloaded)
y	copy the current selection again
,	settings
m	menu (1–9 and 0 pick an entry directly)
esc	clear the search, the selection and the link focus
q	quit

Ctrl+C always quits.

Mouse

Gesture	Action
click a link	open it
wheel	scroll
drag	select, and copy on release (drag past the top or bottom edge to scroll)
double click	select a word and copy it
triple click	select a line and copy it
back / forward buttons	back / forward
Shift + drag	your terminal's own selection, if you prefer it

Copying uses two routes at once: OSC 52 (works over SSH and in most modern terminals) and a system clipboard tool when one is available (wl-copy, xclip, xsel, pbcopy, and on WSL PowerShell or clip.exe), so it works even where the terminal ignores OSC 52. Turn off Mouse support in Settings to leave the mouse entirely to your terminal, or Copy on select to copy with y.

Configuration

Use Settings in the program; it saves for you. The file (wr --config creates it) has everything commented and is equivalent. It is optional, and a broken file never stops you from reading (a warning is shown and the defaults are used).

Key	Default	What it does
width	100	max width of the reading column (40–400); 0 = full width
center	true	center that column
spacing	1	blank lines between blocks: 0 compact, 1 normal, 2 airy
heading_rules	true	a rule under level 1 and 2 headings
code_frame	true	label and frame around code blocks
links	"footnotes"	footnotes, inline or hidden (links stay clickable in all of them)
braille	true	braille decoration; false = plain glyphs
accent	"blue"	color of panels, keys, marks and bars, and the one the headings walk: blue, cyan, green, magenta, yellow, red, gray, white (your terminal's own colors) or orange, violet, teal, pink, lime, slate (fixed presets)
scrollbar	true	scrollbar on the right
footer	true	the footer row
footer_rule	true	the thin rule above the footer
footer_hints	true	shortcut hints on the left
footer_progress	"both"	both, percent, bar or off
footer_chips	true	bookmark star, newer version, search count
mouse	true	wheel, clicks and drag-to-copy
copy_on_select	true	copy when you release the mouse
wheel_lines	3	lines per wheel notch
animations	true	master switch for all animations
anim_scroll anim_reveal anim_panels anim_loading anim_notices	true	each animation on its own
scroll_speed	"normal"	slow, normal or fast
search_engine	"duckduckgo"	duckduckgo, wikipedia, github, or your own URL with %s
homepage	""	page to open when you run wr with no address; empty = the start page
history	true	remember the pages you visit
history_limit	1000	how many visits to keep
cache	true	keep pages on disk
cache_days	30	days a page stays cached
background_refresh	true	refresh a cached page while you read it
[keys]	—	only the key bindings you changed

Where things live

Path	What
~/.config/wr/config.toml	settings and key bindings
~/.cache/wr/	the page cache
~/.local/state/wr/history.jsonl	your history (one JSON line per visit)
~/.local/state/wr/bookmarks.json	your bookmarks

All directories are 0700 and files 0600 (the config is 0644). Privacy: the cache and history store the addresses and content of what you read. Turn history and the cache off in Settings, or clear them from the History panel and the menu.

Cache

A page you already read opens instantly from the cache, and is refreshed in the background while you read.

• If a newer version arrives, the footer shows ● new version (r) and does not change the text under your eyes; r applies it.
• The cache is only used in the interactive view. With --md or in a pipe the page is always downloaded fresh (and the cache is updated).
• If you quit before the refresh finishes, it is discarded without leaving anything half-written.
• Clear it from the menu (this page or everything), with wr --clear-cache, or let it expire after cache_days.

Speed

Measured with an article of ~36 KB of Markdown (1300 lines, 22 code blocks) on WSL2:

	Time
First paint (the loading wave appears)	~30 ms
Cached visit: first text on screen	~50–60 ms (the page then wipes in over ~140 ms)
First visit	~0.4–0.7 s, almost all network
Render the whole document	~18 ms
Re-render (resize, style or link change)	~3 ms

Code is highlighted in parallel, one goroutine per block, and the result is memoized, so resizing the window never tokenizes again.

It uses Bubble Tea v2: it asks the terminal for its background color at startup and moves the palette to the half of the 16 colors that reads on it — the bright one (94) on a dark background, the plain, darker one (34) on a light one. A terminal that does not answer (some multiplexers) keeps the default, which suits a dark one.

How it works

1. Downloads the page (system certificate store, TLS always verified), checks its type and converts it to UTF-8.
2. Takes <article> (or <main>, or <body>) and drops menus, footers, forms, scripts and rows that are just links.
3. Reads each block's language and converts to Markdown with html-to-markdown.
4. Parses the Markdown with goldmark and draws it with a custom renderer into self-contained ANSI lines, recording where every link sits.
5. Bubble Tea handles keys, mouse, resizing and the footer; harmonica drives the springs.

Limits

• Heuristic extraction. It takes <article>/<main>; on unusual pages it may keep noise or cut content.
• No JavaScript and no forms. If the page draws its content with JS, it will come out empty or incomplete. Search engines that need JS will not work as the engine setting; the presets do.
• In-page #links match headings only, by their text (the way most sites generate ids), not arbitrary element ids.
• The language depends on the HTML. If the page does not declare it, the block is shown without color (it is not guessed). mermaid and other languages without a chroma lexer are not colored either.
• Search works per line: a phrase split across two lines of the rendered text is not found.
• Selection copies what is drawn (a heading keeps its mark, a table its borders), except for the code-block frame and the soft wraps described above.
• Very unusual Markdown (embedded HTML, footnotes) is simplified.

Development

git clone https://github.com/sazardev/wr
cd wr
sh scripts/setup-hooks.sh   # once per clone: gofmt, vet and tests on commit
go test -race ./...

The test suite covers the renderer (including link positions), search, selection and copy, cache, config and settings, key bindings, the persistent store, URL handling, and the whole browsing model — clicking, back and forward, failures, overtaken loads, the address bar, history and bookmarks — driven with local pages and synthetic input. It is deterministic: no timing, no network, no terminal emulator.

Security

Page content is untrusted. Before display, control characters (including ESC) are stripped, so a page cannot inject escape sequences into your terminal. This also applies to what is read back from the cache, and an entry whose header does not match the requested URL is discarded. Only http, https and file links are followed; mailto:, javascript: and similar are refused with a notice.

Contributing

Contributions are welcome — issues and pull requests. Commits follow Conventional Commits; releases are cut automatically by release-please from those commits, so the changelog and the tags always match what shipped. Every PR is reviewed by @sazardev and needs a green CI run. See CONTRIBUTING.md for the details.

License

MIT. Use it, modify it, fork it, ship it, sell it — no restrictions. The only thing asked in return is that the copyright notice stays, so the project keeps its recognition.

Documentation

Overview

wr: a terminal reader mode. It fetches a page, extracts the article, converts it to Markdown and shows it in an interactive reader using the terminal's own 16-color ANSI palette (so it follows your theme), with code blocks highlighted per language.

wr URL           open the reader
wr -L URL        no links (text only)
wr --md URL      print the Markdown as is (for pipes)
wr --fresh URL   ignore the cache and download again
wr --clear-cache delete the cache
wr file.html     works with a local file too

A page you already read opens instantly from the cache (~/.cache/wr) and is refreshed in the background for next time.
