Possibility to specify an autoload

[soullivaneuh]

Since Rector uses project's autoload to analyze type of elements, it cannot be installed as project in standalone directory

Why not add the possibility to specify auto-load file with ability of auto-detection? It should be possible PHPStan does that thing.

It would permit later to create phar and/or docker images and run it even on old PHP versions.

EDIT: Plus, using composer bin plugin will install rector on an isolated directory which is the same thing as doing a create-project AFAIK. Am I right? So the issue will be the same.

[TomasVotruba]

Sure. Could you prepare such feature?

[soullivaneuh]

No time right now for it. But I'm sure I'm not the only one interested about that! 😉

[soullivaneuh]

@TomasVotruba May you please specify where the files are autoloaded on your project? Would be a good place to start the work. :-)

[TomasVotruba]

I prefer cooperative solutions of issues :)

I looked into code and.... what about this one?

• eb0d124
• Extended Autoloading, ClassAndMethodResolver, ProcessCommand cleanup #274

Does that work for you?

[soullivaneuh]

Well, when I use this option, I have:

$ ~/tmp/rector/bin/rector process --autoload-file=vendor/autoload.php --level=symfony33 src

Please note I have nikic/php-parser v3.1.3 on my project dependencies. I suspect an autoload conflict.

Having a .phar with re-named namespace would be a solution IMHO. And you may even submit it on https://phar.io/.

I may try to build one and test. Do you know some goods phar building tool? :-)

[soullivaneuh]

We may try this: https://github.com/humbug/php-scoper and box.

[TomasVotruba]

@soullivaneuh I have never made a phar work.

Yea, that's it. Good job to identify this!

Having a .phar with re-named namespace would be a solution IMHO. And you way even submit it on https://phar.io/.

Based on reported issues and composer conflicts, I agree.

We may try this: https://github.com/humbug/php-scoper and box.

Do you an idea how to automate that? Or better - some standalone repository demo with Rector?

[soullivaneuh]

I have never made a phar work.

Me neither, time to start! :-D

I don't know. It seems we don't have specifications about that. It could be a simple Travis configuration to build and push a phar.

PHPStan has is own compiler: https://github.com/fprochazka/phpstan-compiler but it's maybe quite overkill for IMHO.

[TomasVotruba]

Could you prepare simple prototype that just works for your case? That's we really need.
We can continue from there to official phar.

[soullivaneuh]

@TomasVotruba Not on my high priority work but when I'll go back to the rector integration of my company project, I'll give some time on it. 👍

[TomasVotruba]

Ok. I'll be closing this issue as autoload works. It only needs to be documented.

Todo

• add --autoload-file to README.md

[soullivaneuh]

It only needs to be documented.

IMO, #177 should be reopened.
