Summary

  • Switch from the full Super-Linter image to the slim variant (~2 GB smaller), which excludes Rust, .NET/C#, PowerShell, and ARM template linters most consuming repos don't need
  • Add a packageRules entry to the Renovate preset (default.json) and flint's own renovate.json5 that applies regex versioning when the current value starts with slim- — this teaches Renovate how to parse slim-v8.4.0 style tags. The rule only activates for slim tags, so repos using the full image are unaffected (backwards compatible)
  • Document the slim vs full image choice in README

Test plan

  • Run mise run lint:super-linter locally — confirm it pulls the slim image
  • Run mise run fix — confirm autofix works with slim image
  • Verify a consuming repo can override to full image by setting SUPER_LINTER_VERSION to a non-prefixed tag
  • Verify Renovate can parse the slim tag and propose updates

Pull request overview

This PR switches the flint repository from using the full Super-Linter Docker image to the slim variant, reducing image size by ~2 GB. The slim image excludes Rust, .NET/C#, PowerShell, and ARM template linters that most repositories don't require.

Changes:

  • Update SUPER_LINTER_VERSION in mise.toml from v8.4.0 to slim-v8.4.0 with updated SHA256
  • Add Renovate regex versioning directive to parse slim- prefixed tags
  • Document the slim vs full image choice in README, including how consumers can switch between variants

Switch from the full Super-Linter image to the slim variant (~2 GB
smaller), which excludes Rust, .NET/C#, PowerShell, and ARM template
linters that most consuming repos don't need. Repos that need the
full image can set SUPER_LINTER_VERSION to a non-prefixed tag.

chore(main): release flint 0.20.0 (#165)
d5e1401 
## 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.
