Composer 2.4 (release pending) will have a completion script

[dkarlovi]

composer/composer#10320

Don't know when the release is planned.

[dkarlovi]

Note, the same applies to all PHP tools based on Symfony Console 5.4+ since the feature is provided from there. I'm not sure what's the best way to add individual completion scripts though.

[remicollet]

Yes, I'm aware of this new feature.

Shoudl be as simple as dropping a /usr/share/bash-completion/completions/composer file in the package

Of course will take care of this when a beta/RC will be available.

[Seldaek]

You can already do this, 2.3 should support it already AFAIK, but only for command names. 2.4 brings more advanced arg/option completion.

[remicollet]

@Seldaek indeed bash completion file is generated, but doesn't seems to do anything... more work needed here

[remicollet]

Added in the RPM for new release

@remicollet that's awesome! \o/

[remicollet]

generated file is there

but doesn't seems to do anything..

[dkarlovi]

You're right, I've just created it myself locally with 2.3.7 locally and it's not completing commands. It seems the command is exiting with an error.

The feature comes with a --debug flag which can be triggered like so

composer completion --debug

in one shell and use it in another (it's writing to a log file). Maybe @wouterj can help?

[Seldaek]

You need to export SYMFONY_COMPLETION_DEBUG=1 in the shell doing the completion, and then the other shell running composer completion --debug should receive data.

Also make sure to try it with 2.4-dev with composer self-update --snapshot too if you really can't get it to work with 2.3.

[remicollet]

@dkarlovi version 2.4.0RC1 is not available in the testing repository, with bash completion working

$ composer in<tab><tab>
info     init     install  

@Seldaek this doesn't work with current symfony/console 5.4.10, need to be fixed, see symfony/symfony#47022

This probably also affects composer.phar if installed in the search path (ex: /usr/local/bin/composer) or as global installation (ex: $HOME/.composer/vendor/bin/composer)

[Seldaek]

Not sure what doesn't work for you, it works fine for me, but anyway good to see you sent a PR. We'll update as soon as it gets released upstream.

[remicollet]

Not sure what doesn't work for you

If you use "composer" command (thanks to search path), then the [ -f "$sf_cmd" ] will fails.

[Seldaek]

OK maybe it works for me because I use it from a local clone and not as a phar file? I don't quite grasp what your PR is fixing/doing sorry.

[Seldaek]

Ah no sorry I see now what you mean. It worked for me because I always use it with my c alias, but when using composer it indeed fails without your patch 👍🏻

[dkarlovi]

In the end, it's a good thing because the completion script (which is shared across all apps using Console) becomes more robust with each found corner case. 👍

[dkarlovi]

@remicollet installed RC1 package, it works 🍾

[remicollet]

composer 2.4.0 is released and available in the repository

[dkarlovi]

Thanks so much!
