[pkg-php-pear] Bug#725739: Please, make substitution with phpcomposer smarter

[David Prévot]

Hi Nicolas, and pkg-php-tools maintainers,

Thanks for your quick reply, and apologies not to have followed up on
this issue sooner.

Do you have any pointer to that? I’m still quite lost in composer
documentation.

The only information I’ve been able to grab so far is from the source:
https://github.com/composer/composer/blob/HEAD/src/Composer/DependencyResolver/Rule.php#L215
https://github.com/composer/composer/blob/HEAD/src/Composer/Repository/PlatformRepository.php#L74
https://github.com/composer/composer/blob/HEAD/src/Composer/Repository/PlatformRepository.php#L144

It looks like ext- is for PHP extension while lib is for PHP library.

I’m all for fixing our tools if they do not comply with any acceptable
syntax, but I’d welcome pointers to such definition. Mathieu, since you
introduced Composer support in pkg-php-tools, did you manage to get any
“standard” definition, do you have any opinion on the current issue?

Regards

David
