This resolves a build issue with nci/dream2nix and git dependencies.
We can keep most of the helix-specific parts of the flake, we just need
to switch from configuring nci to calling craneLib functions.
We also switch to flake-utils from flake-parts:
* Using rust-overlay with flake-parts directly is unergonomic
(see https://github.com/hercules-ci/flake-parts/discussions/83).
* Removing flake-parts reduces the overall dependencies: rust-overlay
already depends on flake-utils.
Runs of `cargo build` would fail with `ld: framework not found
CoreFoundation` inside a devshell (`nix develop`) on a Darwin host.
This is fixed with two changes:
* Including the `CoreFoundation` package within the devshell's
derivation.
* Switching from `value` to `eval` so that we append to the `RUSTFLAGS`
environment variable rather than overwriting it. `numtide/devshell`
already exposes the `Library/Frameworks` path within the devshell
derivation but it was being overwritten by the manual setting of
`RUSTFLAGS` in `env`.
Here we perform a shallow fetch using builtins.fetchTree. In order
to make this work, we need to specify the `ref' for any repository
that doesn't have `master' as its default branch (I'm not sure why
this limitation exists since we don't need this when performing
the shallow fetch in `--grammar build')
This `ref' field is ignored by helix, so I have left it undocumented
for now, but I could be open to documenting it.
This commit replaces the out-of-date builder in the flake which relied
on submodules for fetching and the compiler for building. Now we
disable fetching and building explicitly with the environment variable
and then use builtins.fetchGit and a derivation mostly derived from
upstream to compile the grammars.
Anecdotally, this is still quite slow as builtins.fetchGit does not
seem to do shallow clones. I'm not sure I see a way around it though
without recording sha256s, which seems cumbersome.
This restores much of the behavior that existed before this PR:
helix will build the grammars when compiling. The difference is that
now fetching is also done during the build phase and is done much
more quickly - both shallow and in parallel.
https://github.com/nix-community/dream2nix is a fairly new and
cool-looking project for adapting upstream package manager outputs
(lockfiles mostly it would seem) for nix.
This should improve the ability to cross-compile. As a more concrete
measure of improvement, `nix flake check' now succeeds 🎉
closes#1746
The queries for Go were updated in ddbf03613d.
The old ref was before this commit, so running helix from the flake
nix flake run github:helix-editor/helix/d62ad8b595a4f901b9c5dba1bb6e8f70ece395bf -- path/to/file.go
will crash because the old grammar's query analysis will fail (because `iota`
was not yet a named node).
This commit updates the version of the grammars that we pull down when building
the flake so that the queries match the grammars. We'll have to do an update like
this whenever a grammar is bumped in a breaking way (which happens fairly often
in tree-sitter) until #1659 comes along and the version of the grammar becomes
tied to the version declared in source.
