Why don't we see all extensions declared on root composer.json file

See with GitHub repo :

• https:/overtrue/phplint/tree/9.0
• https:/overtrue/phplint/blob/9.0/composer.json#L23-L26

Built online for the first time at https:/overtrue/phplint/actions/runs/7056960071/job/19209802647

But when we check with BOX info command, we got :

Only json extension is displayed, but not mbstring. Is there a reason or is it just a bug ?

We can check it online with result https:/overtrue/phplint/actions/runs/7057695166/job/19211827974

Could there be that a mbstring poly fill is present? Thanks to the composer.lock file we remove all the covered extension requirements

[llaville]

Personnaly I'd like the Composer Unused solution that display it even if the symfony/polyfill-mbstring is present

@theofidry I've another use case that I don't understand origin.

I've recently played with PHP Benchmarking framework v1.12.15

And I've noticed that php extensions declared does not match with the box info:general command

Extension zlib is shown as a root definition, while it's not the case in PHPBench composer.json

Confirmed by the composer why ext-zlib command that told us that

There is no installed package depending on "ext-zlib"

Any idea of where it come from ?

[theofidry]

Extension zlib is shown as a root definition, while it's not the case in PHPBench composer.json

Probably from:

Files Compression: GZ

If it's GZ-compressed it requires ext-zlib.

Currently in .requirements.php the source key is filled by either the package name or null for the root. Maybe this could be changed in favour of 'compression algorithm' for this case for clarity

[theofidry]

@llaville do you think it would be good enough to show this as part of a command rather than the info? The difference would be that you compute the requirements before creating the PHAR, as opposed to the info which shows the requirements shipped. This would offer two benefits:

• The output can be changed an more verbose, e.g. to accommodate for your request.
• Adding more information does not come at the cost of changing the requirement checker shipped.
• This allows you to inspect the requirements of an app even if you do not ship the requirement checker.

WDYT?

@theofidry
On my project https:/llaville/umlwriter/tree/3.4.0

By invoking composer why ext-zlib command, I get only

jawira/plantuml-encoding v1.1.0 requires ext-zlib (*)

But when I compile project with BOX 4.6.0@95b0d8e, and run box info command, I get :

As the zlib extension is not defined into the composer.json file of the project, the mention ext-zlib (root) lead to confusion for me !

I'd like to see rather mention like ext-zlib (suggested by humbug/box because files compression is enabled)

That will give something better understandable (but it's only my opinion)

Another use case that lead for me to a confusion, is when an extension is defined as root in the composer.json but did not shown on the RequirementChecker section of the box info, just because there is a polyfill installed.

RequirementChecker:
  Required:
  - PHP ^8.1 (root)
  - ext-dom (root)
  - ext-json (root)
  Conflict:
  - ext-psr (symfony/service-contracts)

On project https:/overtrue/phplint/tree/9.1, the mbstring extension is declared, but does not appear on box info report. And polyfill is only installed by other dependencies, but not declared on root project.

With composer why symfony/polyfill-mbstring, we get on PHP 8.1 platform :

symfony/console v6.4.1 requires symfony/polyfill-mbstring (~1.0)
symfony/string  v6.4.0 requires symfony/polyfill-mbstring (~1.0)

Compare with composer-unused report that did not list the polyfill (installed) but show the mbstring extension

Yes that can be added, not sure if with the exact workding. Note that this is explicitly said in the build output already.

Another use case that lead for me to a confusion, is when an extension is defined as root in the composer.json but did not shown on the RequirementChecker section of the box info, just because there is a polyfill installed.

I totally understand the point, but in #1237 (comment), my question is if having it as part of another command would be good enough.

The reason why I suggest another command is that it's a lot easier and cheaper to add information as part of a Box command. The produced requirement checker is shipped as part of the final PHAR so I prefer to keep the shipped code as stable and light as possible. Which is why listing all the intermediate steps of finding the requirements makes me a bit uneasy.
