lerna 2.0.0-rc.5

v2.0.0-rc.5

on Node.js Yarn

v2.0.0-rc.5 (2017-05-22)

This is the last release candidate.

We need to fix #789 before we can release v2.0.0. All contributions are appreciated!

💥 Breaking Change

• #807 Change exit codes for updated and publish. (@koddsson)

  It is now possible to run lerna publish in CI unconditionally, only publishing when changes are actually detected, and never failing when it decides to not publish anything.

  Previously:

  • lerna publish when there are no updates to publish would throw an error
  • lerna updated when there are no updates would exit 0, making it ineffective as a chained filter (e.g., lerna updated && lerna publish)

  Now:

  • lerna publish when there are no updates is a no-op, exiting successfully with a helpful log message
  • lerna updated when there are no updates will exit non-zero (but not throw an error), enabling it to be an effective filter

🚀 Enhancement

• #726 Add --only-updated option to exec and run subcommands. (@jameslnewell)

  When executing a script or command, only run the script or command on packages that have been updated since the last release. A package is considered "updated" using the same rules as lerna updated.

  lerna exec --only-updated -- ls -la
  lerna run --only-updated test

• #795 Add --parallel flag to lerna exec. (@evocateur)

  With this flag, lerna exec will run the command in all filtered packages
  in parallel, completely ignoring concurrency and topological sorting.

  # transpile modules in all packages as changes occur
  lerna exec -- babel src -d lib -w
  
  # transpile watched modules only in package-foo
  lerna exec --scope package-foo -- babel src -d lib -w

  It is advised to constrain the scope of the command when running with this
  flag, as spawning dozens of subprocesses may be harmful to your shell's
  equanimity (or maximum file descriptor limit, for example). YMMV

• #796 Add --parallel flag to lerna run. (@evocateur)

  This allows simpler invocation of watch scripts, with the caveat that concurrency and topological sorting are completely ignored. This is generally the intention when calling lerna run watch and other similar script targets, hence the additional flag.

  # the following commands are equivalent
  lerna run watch --concurrency=1000 --stream
  lerna run watch --parallel

  Package filtering (--scope and --ignore) is still available when this new flag is being used, and it is advised to narrow the scope of parallel execution when you have more than a dozen packages or so (YMMV).

• #803 Skip git repo check by default in Commands which do not rely on git. (@noherczeg)

• #824 Add json output to ls and updated commands. (@ricky)

  When run with --json, lerna updated and lerna ls will return an array of objects in the following format:

  [
    {
      "name": "package",
      "version": "1.0.0",
      "private": false
    }
  ]

• #829 Prefix piped streams with rotating colors. (@evocateur)
