mise.toml

# Contributor environment for non-Nix builds.
#
# The Nix devshell (flake.nix) is still the recommended path; this file is
# for contributors who use `mise` instead. It pins the toolchain assumed by
# the README's fresh-clone steps and, on macOS, points the linker at the
# active SDK so transitive crate build scripts that link `-liconv`/`-lSystem`
# actually find them. Without that, `nix-darwin`-style setups (where `cc`
# resolves to a wrapper that doesn't auto-inject the SDK lib path) trip
# `ld: library not found for -liconv` inside e.g. `objc2-exception-helper`'s
# build script. No `cargo:rustc-link-search` from any one crate's build.rs
# can reach a transitive build script — the fix has to be at the env layer.

# tauri-cli pinned to the same ^2.9 line the Nix devshell ships
# (`pkgs.cargo-tauri`). The npm package ships a prebuilt binary,
# sidestepping `cargo install tauri-cli` (which itself needs the SDK
# linker fix below). `src-tauri/Info.plist` is picked up automatically
# from its conventional location — no `bundle.macOS.infoPlist` config
# field exists in the Tauri 2 schema, and stricter validators (e.g.
# nixpkgs' cargo-tauri 2.9.6) reject it as an unknown property.

# bundled `ld` doesn't resolve Apple's `.tbd` text-based stubs the same way
# `ld64` does, so links fail with "Undefined symbols for arch arm64" on
# `-lSystem` even when libSystem.tbd is on the search path. /usr/bin/cc and
# /usr/bin/c++ are present on every Mac with Xcode or the Command Line Tools.
