## Project history and usage

nerdfix is a Rust CLI created in March 2023 to find and optionally fix obsolete Nerd Font glyphs in source trees. Its purpose is tightly coupled to the Nerd Fonts v2.3.3 to v3 migration, where many icon codepoints, especially Material Design Icons, moved to avoid conflicts and keep icons in private-use areas.

### Project history

The README explains the motivation directly: Nerd Fonts is used by many UI projects, but some codepoints conflicted with other fonts, especially CJK fonts. Nerd Fonts therefore changed some codepoints; over 2,000 `mdi-*` icons were deprecated after v2.3.3 and targeted for removal in v3. nerdfix indexes the official cheat sheet so maintainers do not have to inspect every glyph manually.

GitHub metadata retrieved on 2026-07-01 showed the repository created on 2023-03-16, written in Rust, with about 468 stars and 7 forks. GitHub releases list v0.1.0 on 2023-03-25 and v0.4.2 on 2024-11-23.

### Adoption history

Adoption is focused but meaningful among Neovim, terminal UI, statusline, prompt, and dotfile maintainers who embedded Nerd Font glyphs before the v3 remap. The repo topics include checker, neovim, nerd-fonts, and rust; the av.db source record shows Homebrew and Nix packaging. The Homebrew formula API reported stable version 0.4.2 and 3 install-on-request events in the prior 30 days when checked on 2026-07-01, so this is a niche repair tool rather than a broadly installed daily CLI.

### How it is used

Package nerds use nerdfix during migrations: scan project files for obsolete glyphs, review candidate replacements, and apply fixes before users upgrade their Nerd Fonts installation. It is most useful in repositories that carry icon literals in Lua, shell, Vimscript, TOML, documentation, prompts, and terminal UI source code.

### Why package nerds care

nerdfix is historically interesting because it captures a rare maintenance problem in terminal tooling: Unicode private-use glyphs became an API surface. The package exists because an upstream font project made a compatibility-breaking cleanup, and downstream terminal packages needed a source-scanning migration tool.
