rune

    rune inspect 

    rune inspect <name> [--root]

    Prints exactly what rune run <name> would execute, and where every part of it came from. It spawns nothing.

    $ cd packages/legacy && rune inspect test
  script      test
  defined     rune.config.ts:12                    root
  overridden  packages/legacy/rune.config.ts:4     + --maxWorkers=1
  command     vitest run --reporter=dot --maxWorkers=1
  shell       /bin/sh -c
  cwd         /repo/packages/legacy
  env         NODE_ENV=test              from .env.test
              RUNE_SCRIPT_NAME=test
              RUNE_ROOT=/repo
              RUNE_PACKAGE_DIR=/repo/packages/legacy
  ignored     DATABASE_URL               .env.test, already set
  path        + packages/legacy/node_modules/.bin

    Chains

    An extends chain prints as a line per link, base first:

    $ rune inspect test:ci
  script      test:ci
  defined     rune.config.ts:8                     root:test
  extends     rune.config.ts:12                    root:test:coverage  + --coverage
  extends     rune.config.ts:16                    root:test:ci        + --reporter=junit
  command     vitest run --reporter=dot --coverage --reporter=junit

    Groups

    For a group, the members are listed with the command each resolves to:

    $ rune inspect ci
  script      ci
  defined     rune.config.ts:22                    root
  kind        serial, stops at the first failure
  members     build     tsc --build
              test      vitest run --reporter=dot
              lint      biome check .

    Arguments

    rune inspect test -- --watch

    Arguments after -- are appended and quoted the same way rune run would, so the printed command is what would run.

    --root inspects the root definition, ignoring package overrides.

    Exit code

    0 when the script resolves. 1 when the name is unknown, with the same suggestion and listing rune run produces.
