Fira Code, but every weight is one notch chunkier. Standard weight metadata (300-700) backed by outlines 50 design-units heavier, so apps that select "Regular 400" get upstream Fira Code's Retina (450) design.
| Style | Metadata | Renders upstream design |
|---|---|---|
| Light | 300 | 350 |
| Regular | 400 | 450 (Retina) |
| Medium | 500 | 550 |
| SemiBold | 600 | 650 |
| Bold | 700 | 750 (extrapolated) |

./scripts/fetch.sh # Fira Code @ 6.2, hash-pinned
uv run chunky-build # dist/ gets ttf, otf, woff2, variable
As an optional second stage, patch the five static TTFs with the official
Nerd Fonts font-patcher into
dist/nerd/. This produces the three stock variants upstream Nerd Fonts ships
(15 files total, 5 weights × 3 variants).
./scripts/fetch_nerd_fonts.sh # FontPatcher.zip @ v3.4.0, sha256-pinned
brew install fontforge # macOS only. Not installable via uv/PyPI
uv run python scripts/build_nerd.py # dist/nerd/FiraCodeChunkyNerdFont*-*.ttf
Prerequisite. FontForge with Python bindings (fontforge on PATH).
On macOS, run brew install fontforge. On Debian/Ubuntu, run
sudo apt install fontforge python3-fontforge.
| Variant | Family | Filename | Use when |
|---|---|---|---|
| Plain | FiraCodeChunky Nerd Font |
FiraCodeChunkyNerdFont-<Style>.ttf |
Most modern terminals/editors, icons overhang the cell (advance stays 1 cell, outline draws wider). |
| Mono | FiraCodeChunky Nerd Font Mono |
FiraCodeChunkyNerdFontMono-<Style>.ttf |
Strict terminals that require every glyph, icons included, to occupy exactly one cell. |
| Propo | FiraCodeChunky Nerd Font Propo |
FiraCodeChunkyNerdFontPropo-<Style>.ttf |
GUI apps / statuslines where icons should render at their natural proportional width. |
Weight metadata (300-700) is preserved in all three variants. Variable font is not patched. font-patcher emits a CRITICAL warning for VFs and the result is not a reliable VF.
Integration checks run with uv run pytest --no-cov -m integration tests/integration/test_nerd.py.
Skip behavior works as follows. The whole module is skipped only when dist/nerd has no
.ttf files at all. Individual parametrized (variant, style) rows skip when
that specific dist/nerd output is absent. But once any output exists, the
completeness test (checking all 15 files and their PostScript names) hard
fails if the full set isn't present. A partial dist/nerd counts as a
build defect and fails the test.
After building the stock and Nerd Font outputs, create deterministic release archives and their checksums:
uv run python scripts/package_release.py
The archives and SHA256SUMS are written to release/.

Install directly with fully qualified cask names. Homebrew automatically taps the repository and trusts only the requested cask:
brew install --cask validatedev/tap/font-fira-code-chunky
brew install --cask validatedev/tap/font-fira-code-chunky-nerd-font
To use short cask names, tap and trust the repository once:
brew tap validatedev/tap
brew trust validatedev/tap
brew install --cask font-fira-code-chunky
brew install --cask font-fira-code-chunky-nerd-font
Copy dist/ttf/*.ttf to ~/Library/Fonts. Coexists with regular Fira Code.
For Nerd Font variants, copy dist/nerd/*.ttf to ~/Library/Fonts the same way.
If a stale build seems installed, run sudo atsutil databases -remove and re-login.
