Description

The five developer commands now mean the same thing in every Calysto repo: install, test, cover, typing, and lint.

Two things were confusing before. lint ran a hand-picked subset of pre-commit hooks while a separate pre-commit recipe ran all of them, so neither name described what it did. The lint recipes also did not control their own environment. Because just test syncs to the test group and prunes everything else, running it before just lint left no pre-commit in the environment. Each recipe now syncs the groups it needs, so any order of commands works.

Changes

• Renamed the run-all-hooks recipe from pre-commit to lint
• Added lint-all for hooks that only run at the manual stage, such as markdown-link-check
• The lint recipes now sync the dev group before running, matching what the other recipes already did
• Updated the contributing guide to match

Backwards-incompatible changes

just pre-commit no longer exists. Use just lint, or just lint-all to include the manual-stage hooks.

Testing

• just lint passes
• just typing passes with no issues in 113 source files
• just test passes, 489 tests with 68 skipped
