concurrently

• Add yarn support (#171 -- big thanks to @igrayson!)

• bin: Fix concurrently --version

More than anything, v4 is just a big refactor to allow changes to be made faster and more reliably.
It does feature some small breaking changes, and maybe even fixes some longstanding bugs.

Breaking changes

• breaking

  The CLI option --allow-restarts is no more.
  Instead, just set --restart-tries to something greater than 0.

• breaking

  Input handling is now opt-in via --handle-input flag.
  It does come with some specific input parsing that would make it difficult for you to use it with some tools.

• breaking

  Setting prefix to none will now actually not prefix commands' outputs.
  Previously, it would prefix with .

• breaking

  SIGINTs/Ctrl+C will now be handled gracefully.
  No more exiting with code 1 or tweaking --success flag.

No more null exit codes (#133)

That's a pretty bad bug that existed till now. You won't see a log like this anymore:

[1] npm run lint-watch exited with code null

What you will see going forward is the actual exit signal:

[1] npm run lint-watch exited with code SIGTERM

For Windows users, this will invariably still be exit code 1.

concurrently finally gets a shiny ✨ programmatic API!

Closes #101, #112. Maybe even #103.

const concurrently = require('concurrently');
await concurrently([
	'npm:watch-*',
	{ name: 'server', command: 'nodemon' }
], {
  prefix: 'name',
  killOthers: ['failure'],
  restartTries: 3
});

Check the docs here for some info on how to use it.

• Expand npm: prefix to npm run

• Support wildcard expansion for npm:something-*/npm:*-like commands

• Handle stdin (#121, #128)

• Upgrade own chalk version

BIG thanks to @pgraham for contributing with the most important changes of this version!

• Add support for colors in subprocesses when they use chalk (#49, #86, #87)

• Fix killing processes in Windows gitbash (#74, #67)

• Upgrade spawn-default-shell dependency to v2.0.0. This means that shells in Linux and Mac will spawn with the --login flag, allowing you to make use of /etc/profile, ~/.profile, and etc

• The timestamps are now handled by date-fns instead of Moment.js. They share the same date format patterns.

Also, this version drops support for Node 0.12. We're only supporting Node 4+.

This release includes huge amount of improvements. Major updates:

• Fix issues with Windows and Appveyor CI was added to ensure Windows compability

• Improve shell support. spawn-default-shell is used to spawn shell commands. It uses the best available shell on your platform. You can also customize the used shell with SHELL and SHELL_EXECUTION_FLAG environment variables. Minor caveat: it means that e.g. piping works on your linux machine but may not work as expected on Windows. This leaves more responsibility to the users of concurrently.

• Handle SIGTERM and SIGINT signals correctly

Closes these PRs: #58 #57 #56 #53 #47 #45 #43 #42 #40 #21. Closes these issues: #52 #50 #41 #31 #28 #7 #3.

This shouldn't break anyone's concurrent commands but concurrent is now deprecated. Migration from 1.x -> 2.x is simply to rename concurrent -> concurrently.
