Rastin
Cordis bundle for the DeepSeek Harness Web GUI: Persian RTL layout with embedded fonts.
Features
- Persian RTL — chat, queue, and question/plan-review surfaces read right-to-left on the IranYekanX face, shipped as base64 woff2 inside the bundle.
- Sidebar terminal font — FiraMono Nerd Font Mono. xterm draws on canvas, so CSS alone can't restyle glyphs; the bundle embeds the face and patches the canvas 2d
font setter scoped to [data-sidebar-terminal].
- Todo dock opens by default — host mounts it collapsed; the bundle clicks it open once (user can re-collapse).
- LTR islands — code blocks, tool-call/command rows, changed-files cards, and process-status labels stay LTR inside the RTL surfaces.
- RTL arrow mirror — flow arrows (← → ⇐ ⇒) in RTL prose point the RTL way via a per-glyph mirror span; copy text stays intact.
Requirements
- Node.js 24 (matches ci) + pnpm 12 (
packageManager).
Setup
pnpm install --frozen-lockfile
pnpm setup # git hooks: pre-commit = prettier check, pre-push = build + self-check
Workflow
pnpm build # src/client.template.js + fonts → client.js (generated, git-ignored)
pnpm test # build + self-check (mocked ctx, cleanup assertions)
Edit src/client.template.js — never client.js directly.
Files
src/client.template.js — editable source (placeholders __IRANYEKAN_B64__, __FIRAMONO_B64__).src/index.js — host half (no rendering).src/cordis.patch.yml — bundle slot patch (rastin / @amir83nasr/rastin).scripts/build.mjs — template + fonts → client.js.scripts/self-check.mjs — behavioral wiring check.fonts/ — embedded faces (.woff2).locale/ — bundle metadata (en.json / fa.json).client.js — generated output (git-ignored).
How it works
- One style seat on
shell.overlay (rastin-style) injects @font-face + RTL rules.
installTerminalFont() patches CanvasRenderingContext2D.font, scoped to the sidebar terminal; reverts on cleanup.autoOpenTodoPanels() observes the DOM and opens collapsed todo panels once; disconnects on cleanup.
Release
