feat: support NATIVE env var for container-free linting by zeitlinger · Pull Request #107 · grafana/flint

zeitlinger · 2026-03-13T11:19:59Z

Summary

lint:super-linter now accepts NATIVE=true env var (mirrors existing AUTOFIX=true pattern)
New lint:fast grouping task (super-linter + links) — skips renovate-deps
New native-lint meta-task: NATIVE=true mise run lint:fast
pre-commit now runs lint:fast natively (was only super-linter before)
Removed autofix from pre-commit task (check-only)
Modernized lint:super-linter-native and pre-commit to use structured run/env syntax
Updated README: documented env var alternatives, lint:fast, native-lint examples

Test plan

NATIVE=true mise run lint:super-linter — runs native linters
mise run native-lint — propagates NATIVE, runs super-linter + links
mise run lint:super-linter --native — CLI flag still works
mise run fix — AUTOFIX still propagates through full lint
mise run lint — still runs all lints including renovate-deps

The --native flag on lint:super-linter can now also be set via NATIVE=true env var, mirroring how AUTOFIX=true already works. This allows the top-level lint meta-task (which uses depends) to propagate native mode — mise's depends can't forward CLI flags but env vars flow through naturally. Adds a native-lint task and modernizes lint:super-linter-native and pre-commit to use structured run syntax where applicable. Signed-off-by: Gregor Zeitlinger <gregor.zeitlinger@grafana.com>

Pull request overview

This PR extends the existing lint task workflow to support running Super-Linter in “native” (container-free) mode via NATIVE=true, enabling easier local/dev and constrained-environment linting while keeping the existing CLI flags and AUTOFIX patterns.

Changes:

Added NATIVE=true env var support to lint:super-linter (in addition to the --native flag).
Added a native-lint meta-task and updated native/pre-commit tasks to propagate native mode via env.
Updated README to document env-var-based mode propagation and native linting examples.

lint:fast runs super-linter + links (the fast lints). lint still runs everything including renovate-deps. native-lint and pre-commit now target lint:fast to avoid spawning Renovate. Signed-off-by: Gregor Zeitlinger <gregor.zeitlinger@grafana.com>

- Add lint:spotless task for Java format checking - Add lint:fast grouping (super-linter + links + bom + example-poms + spotless) - Add native-lint task (NATIVE=true, no container needed) - Switch pre-commit to NATIVE=true mise run lint:fast - Exclude generated CHANGELOG.md from super-linter and lychee Depends on grafana/flint#107 (NATIVE env var) and grafana/flint#112 (v8.5.0 version mapping).

## Summary - Add `lint:spotless` task for Java format checking - Add `lint:fast` grouping task (super-linter + links + bom + example-poms + spotless) - Add `native-lint` meta-task (`NATIVE=true`, no container needed) - Switch `pre-commit` to `NATIVE=true mise run lint:fast` ## Blocked on - grafana/flint#107 — `NATIVE` env var support for `lint:super-linter` - grafana/flint#112 — v8.5.0 version mapping for `setup:native-lint-tools` After those merge, update the flint SHA in `mise.toml`. ## Test plan - [ ] `mise run native-lint` passes after flint update - [ ] `mise run lint` still works in CI (container mode) - [ ] Pre-commit hook works with native linting --------- Signed-off-by: Gregor Zeitlinger <gregor.zeitlinger@grafana.com>

## flint v0.20.0 — Rust rewrite flint has been rewritten from scratch in Rust. The bash + Docker stack is replaced by a fast, cross-platform native binary with no container dependency. ### Highlights - **Native binary** — no Docker, no bash wrappers; runs anywhere mise can install a Rust crate - **Parallel linting** — all checks run concurrently - **Diff-aware** — only checks files changed since the merge base by default (`--full` for everything) - **`flint update`** — migrates obsolete `mise.toml` tool keys automatically (e.g. `ubi:` → `github:`, `npm:markdownlint-cli` → `npm:markdownlint-cli2`) - **`flint hook install`** — installs a pre-commit hook without any mise task knowledge - **New linters**: `gofmt`, `google-java-format`, `ktlint`, `dotnet-format`, `markdownlint-cli2`, `xmllint` (via `cargo:xmloxide`), `license-header` (pure-Rust, no binary) - **Windows support** — ktlint self-executing JAR handled via explicit `java -jar` invocation ### Migration See [AGENTS-V2.md](https://github.com/grafana/flint/blob/main/AGENTS-V2.md) and [README.md](https://github.com/grafana/flint/blob/main/README.md) for full setup instructions. Quick reference for existing consumers: ```toml [tools] # While installing from source (pre-crates.io release): "cargo:https://github.com/grafana/flint" = "branch:main" [env] FLINT_CONFIG_DIR = ".github/config" [tasks.lint] run = "flint run" [tasks."lint:fix"] run = "flint run --fix" ``` Remove: `lint:super-linter`, `lint:links`, `lint:renovate-deps`, `setup:native-lint-tools`, `setup:pre-commit-hook` tasks. Run `flint update` to auto-migrate any obsolete tool keys. > [!NOTE] > The changelog below includes entries from the legacy v1 bash era — see [README-V1.md](https://github.com/grafana/flint/blob/main/README-V1.md) for v1 docs. --- ## [0.20.0](flint-v0.19.0...flint-v0.20.0) (2026-04-13) ### Features * add flint v2 Rust binary ([#139](#139)) ([19f2b25](19f2b25)) * add native linting mode and version mapping infrastructure ([#93](#93)) ([24b06da](24b06da)) * add Renovate shareable preset for consuming repos ([#17](#17)) ([8a06590](8a06590)) * consolidate link checking and add autofix flags ([#7](#7)) ([086a5e9](086a5e9)) * flint update command, explicit JAR flag, v0.20.0 ([#146](#146)) ([b43bf52](b43bf52)) * handle line-number anchors and issue comments globally ([#56](#56)) ([cf751df](cf751df)) * **links:** add GitHub URL remaps for line-number and fragment anchors ([#28](#28)) ([5b59065](5b59065)) * **links:** auto-remap base-branch GitHub URLs to PR branch ([#18](#18)) ([dd6cc61](dd6cc61)) * **renovate:** support SHA-pinned URLs in Renovate preset ([#21](#21)) ([4fd1f28](4fd1f28)) * **super-linter:** default to slim image ([#24](#24)) ([c8eeab8](c8eeab8)) * support NATIVE env var for container-free linting ([#107](#107)) ([0a8193d](0a8193d)) ### Bug Fixes * activate mise environment in native lint mode ([#123](#123)) ([d0fec45](d0fec45)) * add 'mise run fix' hint to lint failure output ([#90](#90)) ([5b4ad5d](5b4ad5d)) * decouple version mapping generation from pinned super-linter version ([#112](#112)) ([5370e77](5370e77)) * **deps:** update rust crate crossterm to 0.29 ([#156](#156)) ([c59ae3e](c59ae3e)) * **deps:** update rust crate similar to v3 ([#160](#160)) ([684be4e](684be4e)) * **deps:** update rust crate toml to v1 ([#161](#161)) ([3aae614](3aae614)) * **deps:** update rust crate toml_edit to 0.25 ([#158](#158)) ([42d9efd](42d9efd)) * exclude GitHub compare links from lychee checks ([#10](#10)) ([e714608](e714608)) * fail native lint when enabled tools are missing ([#111](#111)) ([163bb6b](163bb6b)) * improve link checker reliability against GitHub rate limiting ([#95](#95)) ([7a5282d](7a5282d)) * include staged files in native lint file list ([#135](#135)) ([34412d6](34412d6)) * **links:** add regex anchors to remap patterns ([#19](#19)) ([2e17348](2e17348)) * native lint in worktrees, trust toml, use ec binary, drop isort ([#134](#134)) ([8594bba](8594bba)) * **release-please:** fix footer not appearing on release PRs ([#40](#40)) ([d7a55e4](d7a55e4)) * remap same-repo GitHub URLs to local file paths ([#100](#100)) ([b4feadd](b4feadd)) * **renovate-deps:** forward GITHUB_TOKEN as GITHUB_COM_TOKEN ([#132](#132)) ([4d6510b](4d6510b)) * replace broken release-please PR comment with docs ([#12](#12)) ([817b37d](817b37d)) * run shellcheck on .bats files in native mode ([#137](#137)) ([a4fd3f8](a4fd3f8)) * strip Scroll to Text Fragment anchors in link checks ([#86](#86)) ([b630cdf](b630cdf)) * tighten markdownlint config for native mode ([#106](#106)) ([6ef25b2](6ef25b2)) * use remap instead of exclude for issue comment anchors ([#58](#58)) ([656f355](656f355)) --- > [!IMPORTANT] > Close and reopen this PR to trigger CI checks.
