The Meson 1.5 feature essentially internally translates Cargo.lock entries +# to .wrap files, and that translation is incredibly straightforward, so let's just +# use a simple Python script to generate the .wrap files ourselves while we wait for +# Meson 1.5. Weirdly, it seems Meson will only detect dependencies from other +# dependency() calls, so we have to specify lix-doc's two top-level dependencies, +# rnix and rowan, manually, and then their dependencies will be recursively translated +# into more dependency() calls. +# +# When Meson translates a Cargo dependency, the string passed to `dependency()` follows +# a fixed format, which is important as the .wrap files' basenames must match the string +# passed to `dependency()` exactly. +# In Meson 1.4, this format is `$packageName-rs`. Meson 1.5 changes this to +# `$packageName-$shortenedVersionString-rs`, because of course it does, but we'll cross +# that bridge when we get there... +# +# [1]: https://github.com/mesonbuild/meson/commit/9b8378985dbdc0112d11893dd42b33b7bc8d1e62 + +run_command( + python, + meson.project_source_root() / 'meson/cargo-lock-to-wraps.py', + meson.current_source_dir() / 'Cargo.lock', + meson.project_source_root() / 'subprojects', + check : true, +) + +# The external crate rowan has an ambiguous pointer comparison warning, which +# we don't want to fail our whole build if werror is on. +subproject('rowan-rs', default_options : ['werror=false']) + +rnix = dependency('rnix-rs') +rowan = dependency('rowan-rs') + +lix_doc = static_library( + 'lix_doc', + sources : files('src/lib.rs'), + rust_abi : 'c', + dependencies : [ + rowan, + rnix, + ], + # If an installed static library depends on this target, then Meson will force + # that to link with `-Wl,--whole-archive`, unless we also install this target. + # `-Wl,--whole-archive` can cause some Problems when linking multiple nested + # static libraries, so let's just install the damn thing. + install : true, +) + +liblix_doc = declare_dependency( + link_with : lix_doc, +) |
