Mohamed Boudra 5b22aedaff feat(app): polish file explorer tree with material icons and visual refinements
Replace lucide file icons with colored SVGs from material-icon-theme covering
53 language/filetype-specific icons. Add chevron expand indicators for
directories, indent guide lines, rounded rows, and restyle the header toolbar
to match the git diff pane pattern.

File Icons

The file explorer uses colored SVG icons from material-icon-theme (installed as a dev dependency in packages/app).

Icons are inlined as SVG strings in:

packages/app/src/components/material-file-icons.ts

This file is auto-generated. Do not edit it by hand.

How it works

  • SVG_ICONS maps icon names (e.g. "typescript") to raw SVG strings
  • EXTENSION_TO_ICON maps file extensions (e.g. "ts") to icon names
  • getFileIconSvg(fileName) returns the SVG string for a given filename, falling back to a generic file icon

Adding a new icon

  1. Find the icon name in the material-icon-theme manifest:
node -e "
const m = require('./node_modules/material-icon-theme/dist/material-icons.json');
console.log('fileExtensions:', m.fileExtensions['YOUR_EXT']);
console.log('languageIds:', m.languageIds['YOUR_LANG']);
"
  1. Verify the SVG exists:
cat node_modules/material-icon-theme/icons/ICON_NAME.svg
  1. Add two things to material-file-icons.ts:

    • The SVG string in SVG_ICONS:

      "icon_name": `<svg ...>...</svg>`,
      
    • The extension mapping in EXTENSION_TO_ICON:

      "ext": "icon_name",
      
  2. Run npm run typecheck to verify.
