flint v2 — first binary release

Full rewrite from bash scripts wrapping super-linter to a native Rust binary orchestrating mise-installed tools directly. Last v1 release was v0.9.2; this is the first working v2 binary release.

Why

• Speed: no container pull, no full-repo scan — diff-aware by default (--from-ref / --to-ref), parallel check execution across files.
• Native tools: each linter installed via mise from its upstream source (github:, ubi:, npm:, cargo:) — no bundled versions, transparent to Renovate.
• One entry point: flint run / flint run --fix replaces lint:super-linter, lint:links, lint:renovate-deps, setup:native-lint-tools.
• Cross-platform: Linux x86_64/arm64, macOS x86_64/arm64, Windows x86_64 binaries.

Install

# mise.toml
[tools]
"github:grafana/flint" = "0.20.2"

[env]
FLINT_CONFIG_DIR = ".github/config"

[tasks.lint]
run = "flint run"

[tasks."lint:fix"]
run = "flint run --fix"

Bootstrap a repo with flint init (interactive config scaffold).
Install a pre-commit hook with flint hook install.

Linters supported

Highlights

• Formatter category — formatters marked with .formatter() are automatically excluded from editorconfig-checker, preventing double-reporting.
• Special checks — link checking and renovate-deps are first-class, not shell-outs. license-header is a pure-Rust check (reads first N lines, substring-matches configured text).
• Fix mode — flint run --fix runs per-linter fix commands in-place.
• Diff mode — without flags, runs only on files changed since merge base with origin/main. --full for full-repo, --from-ref/--to-ref for arbitrary ranges.
• Obsolete key detection — flint update non-interactively migrates mise.toml entries when a linter's upstream key changes (e.g. npm:markdownlint-cli → npm:markdownlint-cli2).
• Windows — .windows_java_jar() registry flag for JAR-backed tools (ktlint); quote_path + shell_words for double-quote path handling.

Documentation

• README.md — getting started, configuration reference
• AGENTS-V2.md — architecture and contribution guide
