TODO

  • Proper support for opam repo management.
  • Implement depexts.
  • Warn on md5 hashes.
  • Refactor builder.nix.
  • Refactor overrides.
  • Better depexts mapping:
  • Filter invalid depexts names.
  • Run opam actions natively with Bos.
  • Apply "with-test" var when extracting install.
  • Use native nixpkgs to build onix itself.
  • Use the same compiler for onix and project build.
  • Drop fpath, use OpamFilename.´
  • Improve logging.
  • Properly fix ocaml env var export for deps.
    • Using hooks seems is problematic due to multi-export (fails with "Argument list too long").
    • Computing the dep closure is more deterministic albeit potentially costly.
  • Replace build ctx json with OCAMLPATH lookup.
    • Consider installing the opam file as $libdir/$pkg/onix-opam or even overwritting ./opam.
  • Do we need to include opam in build ctx json or can we pass repo-url?
    • Do we really want opam files for all deps (for opam's depends var)?
  • Use builtins.filterSource for ./. src to exclude unwanted dirs (gitignore, _build).
  • Define build/test/dev dependencies separately in lock file?
  • Handle strange version names in nix paths (like dream-pure-1.0.0-alpha2).
    • So we can correctly set up buildInputs/nativeBuildInputs, etc.
  • Changing project's opam file currently triggers full scope rebuild?
  • Support gitignore.
  • api.lock could be a derivation.
  • Support dependency flags: with-build with-test with-doc with-dev/with-tools?
    • Expose flags in the api module.
  • Pass ignore file as a parameter: --ignore-file=(default=.gitignore).
  • Read ONIX_REPO_URL.
  • Allow setting dep flags for both the project and the deps.
  • Nix store path parsing does not work for nix develop: pass nv to actions.
  • Ensure valid pkg names (exclude ~).
  • Use two sets for depexts: nix * other instead of nix | other.
  • Support zip unpacking (tezos?).
  • Use builtins.foldl’.
  • Handle .config files (like conf-binutils.config). Is this related to opam's flag: conf.
  • Use nix-prefetch-url.
  • Use nix-prefetch-git for repo fetching.
  • Force symlink resolution of locally vendored deps. Otherwise we get "chmod: changing permissions of 'melange': Operation not permitted"
  • Make sure that incremental/partial changes to the lock file (and opam file) are possible withou full rebuild.
  • Make dev tools work: vscode/vim plugins.
  • Fix ocaml env vars propagation for shell.
  • Use nix-prefetch-git for pins.
  • Remove empty libdir after install (should at least have opam!!)?
    • Install repo's opam, the monads pkg does not install opam for example.
  • Document that opam vars can be set by defining OPAM_VAR_pkg_name.
  • Consider using opaline.
  • Implement onix shell.
  • Implement onix build.
  • Add --lock-file argument to actions.
  • Add a command similar to opam var to lookup package variables?
  • Improve error-handling.
  • Build any package without a project onix build utop or similar.
  • Make depends/depexts optional fields. No longer needed for new build context.
  • Handle empty lock file.
  • Fetch opam extra-source files.
  • Always patch shebangs?
  • Do we need to pass --ocaml-version? Can we expect OCaml to be always in the path?
    • Pass package nv to opam actions. This will fix the develop $out issue.
  • Add an example with overrides.
  • Support static compilation.
  • Handle setenv and build-env.
  • Support cross-compilation.
  • Add flakes support.
  • Use strictDeps. This will require handling conf- packages in the lock file.
    • Added a build option.
  • Handle lock file without ocaml.
  • Version the lock file.
    • Add version, packages and repo fields.
  • Consider using joinSymlinks/linkFarm(!) to create a build scope.
    • Use this for the onix build command, i.e., result will contain the root outputs.
  • Consider using makeScope for the scope.
  • Handle pkg:installed?enable:disable.
  • Stop using emptyPkg. Override the base compiler only?
  • Would depending on the content of the opam files (as opposed to the opam file in the repo) improve cache reusability?
  • Handle enable-ocaml-beta-repository.
    • In theory this is now working with multirepos.
  • Should we include the opam field in the lock pkg? The opam file path can be reconstructed from the repo path and pkg nv.
  • Hanlde "sys-ocaml-version" var.
  • Group dep flags.
  • Setup the opamverse test.
  • notty: seems to have a missing propagated build dep.
  • When adding nativeBuildInouts we need to include all transitive deps.
  • Run commands with shell?
  • Filter out invalid nixpkgs names: "pkgs.devel/librdkafka"
  • Slacko base-no-ppx for lwt?
  • Support a vendoring/forking workflow (override src?).
  • Opam-installer requires ocaml 4.13 by default. Use the same version as the rest of the build.
  • Consider adding opam-installer to lock file to avoid pulling pkgs.opam-installer.
  • Document diffs:
    • Support compiler option packages.
    • Support dev tools, test, doc.
    • Support pins.
    • Support cross.
    • Support lock-file.
    • Support easy building of any package without nix lock.
    • Support offline mode.
    • Prefetch packages to compute sha256 when md5 is used.
    • Support multiple opam repositories.
  • Help debug nix paths (eg show opam repo path)
  • When the scope is built but there was a pkg override do we still build the pkg? Must not.
  • Replace hardcoded ocaml nix versions with a call to get currently available version from ocaml-ng.
  • Make sure that unsupported compiler combinations error out.
    • compiler: base|system, options package (warn on pkg with compiler flag?)
    • compiler: variants, no valid version in nix
  • Add self pkg to OPAMPATH[0]
  • Use rec in lock.
  • Do not include opt deps in lock.
  • Include expanded patch/build/install commands in lock file.
    • This is not easy because substs need to happen during patch phase, which requires var lookup.
  • Ensure that strings, not paths, are passed to build/opamFiles.
    • Using toString is not sufficient, the lock file will contain an absolute path.
  • If a dep is already in *buildInputs, does it need to be in nativeBuildInputs?
  • Test substs in a patch:
  • There are no more nulls in lock file, avoid checks.
  • Consider using attrsets (name => x) for representing deps to avoid duplicates when (++).
  • Add support for local repos.
  • Host's OPAMPATH is used when -i is not passed to develop for shell target.
  • Formatting dune files is slow with vscode.
    • Which uses nix develop -i -c $prog $args.
  • Can we symlinkJoin an opam root?
  • How to get compatibility with OCaml Platform? Can we fake opam's CLI?
  • Pass verbosity to top-level onix attrset.
  • Fetch the repository before passing it to onix lock.
  • Input path does not currently support opam files because the package name cannot be extracted.
  • Do we need the "root" version or can we use "dev" in the lock file?
    • Removed root version.
  • It's currently impossible to avoid reading root packages when opam deps are passed.
  • Deps: support overriding to nixpkgs package and providing remote opam URL.
  • SIGSEGV when the path contains a large file (during gitignore?).
  • Better roots tracking (for deps with constraints)?
  • Activate dep flags for a selected list of deps?
  • Allow passing dep flags (test, doc, dev-setup) to each dependency.
  • Changing the repo hash invalidates cache even if opam files did not change? Is it possible to depend on opam file contents?
    • Fixed.
  • Fix lock var generation when not all vars are passed.
  • When evaluating arch use a "delayed" env var version.
  • Document that opam vars can be added to drv.
  • Install repo's opam file.
  • When running nix profile install github:odis-labs/onix why are so manny deps fetched (like clang).
  • Lookup all opam files by default on onix lock.
  • Improve verbosity of onix lock.
  • Add a shell hook to shell to check if there are any opam variables.
