## Project history and usage

bold is a Zig-written drop-in replacement for Apple's system linker `ld`, focused on Mach-O linking on Apple platforms.

### Project history

The official README says bold used to be emerald, but the broader emerald driver effort was split off because of maintainer time constraints. The README positions bold as a direct competitor to LLVM lld and Apple's linker, with benchmark comparisons against Apple's rewritten linker, classic Apple ld, and lld.

### Adoption history

bold is a young specialist developer tool. The input package facts show Homebrew and Nix packaging, which is the expected adoption path for an experimental linker aimed at macOS and Zig-adjacent systems developers.

### How it is used

Typical usage is building with nightly Zig, then passing bold to C or C++ compilers with `-fuse-ld=bold` for clang or `-B/path/to/bold` for gcc-style toolchains.

### Why package nerds care

bold is interesting to package nerds because linkers are rarely casual dependencies; packaging it means exposing an alternate toolchain component that must match platform object formats, compiler driver behavior, and system linker expectations.

### Timeline

- 2026: The Codeberg repository metadata records the public bold repository creation.
- 2026: The README describes bold as the focused successor to the earlier emerald effort.

### Related projects

- Related projects include Apple ld, Apple's classic ld mode, LLVM lld, Zig, and the earlier emerald project.
