feat(conda): graduate conda backend out of experimental by jdx · Pull Request #9544 · jdx/mise

jdx · 2026-05-02T15:05:25Z

Summary

The conda backend has been stable in practice — install/uninstall, lockfile resolution, dependency handling, and library-path patching are all covered by the e2e suite (e2e/backend/test_conda exercises ruff, bat, jq with deps, and postgresql with ~23 transitive deps). Drop the experimental gate so users no longer need to set MISE_EXPERIMENTAL=1 to use it.

Changes:

Remove conda::EXPERIMENTAL constant and the ensure_experimental("conda backend") check in install_version_.
Drop the BackendType::Conda branch in is_experimental().
Remove the experimental badge from docs/dev-tools/backends/conda.md and the backends index.

dotnet, s3, and spm remain experimental and are unchanged.

Test plan

cargo check --all-features (verified locally — clean).
mise run test:e2e test_conda still passes (e2e harness sets MISE_EXPERIMENTAL=1 globally so behavior is unchanged in CI; this PR's effect is for end users not setting that var).
mise install conda:ruff works without MISE_EXPERIMENTAL=1 set.

🤖 Generated with Claude Code

Note

Low Risk
Low risk: removes the experimental gate for the conda backend and updates docs; no functional changes to install/solve logic beyond allowing it to run without MISE_EXPERIMENTAL enabled.

Overview
Graduates the conda backend out of experimental by removing the experimental flag/constant, dropping BackendType::Conda from is_experimental(), and eliminating the Settings::ensure_experimental("conda backend") check during install.

Updates backend documentation to remove the experimental badge for conda in both docs/dev-tools/backends/conda.md and the backends index.

Greptile Summary

Graduates the conda backend out of experimental by removing the EXPERIMENTAL constant, the ensure_experimental("conda backend") guard in install_version_, and the BackendType::Conda arm in is_experimental(). Documentation badges are updated to match. All three removal sites are consistent and no stale references to conda's experimental status remain in the codebase.

Confidence Score: 5/5

This PR is safe to merge — it removes a narrow, well-scoped experimental gate with no functional changes to the conda backend itself.

All three removal sites (constant, is_experimental match arm, ensure_experimental call) are correctly handled and consistent. No stale references to conda's experimental status exist in the codebase. Remaining experimental backends (dotnet, s3, spm) are untouched. Docs are updated to match.

No files require special attention.

Important Files Changed

Filename	Overview
src/backend/conda.rs	Removes the `EXPERIMENTAL` constant and `ensure_experimental` guard from `install_version_`, graduating conda to stable.
src/backend/backend_type.rs	Drops the `BackendType::Conda` arm from `is_experimental()` and removes the now-unused `conda` import; remaining experimental backends (dotnet, s3, spm) are unchanged.
docs/dev-tools/backends/conda.md	Removes the experimental badge from the conda backend page heading.
docs/dev-tools/backends/index.md	Removes the experimental badge from the conda entry in the backends index; dotnet, s3, and spm badges are correctly retained.

Code Review

This pull request promotes the Conda backend from experimental to stable by removing experimental badges in the documentation and eliminating the experimental mode checks and constants in the source code. I have no feedback to provide.
