[Console] Activate the profiler in the commands

Would it be interesting to be able to activate the profiler in the commands? Maybe something like this:

$ php bin/console app:do:something --enable-profiler

// do something 

Profiler token: http://localhost:8000/_profiler/b50ac4

The issue is that the Profiler is tied to profile a Request currently, and there is no Request in the CLI (unless you do CLI over HTTP of course).
So this would require a full rewrite of the profiler first, to decouple it from HttpFoundation

@stof is write when he says that the profiler is tied with HTTP requests. Rewriting the profiler would not help as anyway most panels needs a request. So, I'm closing this one as it would mean developing a new profiler for CLI applications.

hi @fabian, i think this would be a great addition to the symfony dx (i.e. profiled http-client requests and doctrine queries issued by a command would be of immense help in a development process)

any chance you've changed your stance on this? as per comment: #39114 (comment)

these issues seem related:

• Do not wire Traceable Event Dispatcher in CLI #32422
• [RFC][WebProfiler] Show services #39114
• Display deprecated triggered during cache warmup #30089

thanks

Hi,

The profiler and web toolbar are really valuable tools, but the lack of cli/command/messenger support makes debugging much harder in some scenarios. For example debugging failing functional tests (running through a cli tool/command like behat or phpunit) is quite complicated.

I have created 2 bundles that help bring the profiler/toolbar experience to the terminal:

• https://github.com/sourceability/console-toolbar-bundle
  • The code to render the toolbar in the terminal using twig/DomCrawler: https://github.com/sourceability/console-toolbar-bundle/blob/39ee27aa14ec93710d0f1cecd12d72f961a23a21/src/Console/ProfilerToolbarRenderer.php
• https://github.com/sourceability/instrumentation-bundle
  • The relevant (hacky) code that works around the profiler/http coupling: https://github.com/sourceability/instrumentation-bundle/blob/a877f6cb527c88d9d2121c87a202c104f35f3531/src/Profiler/SymfonyProfiler.php

Native support would be really nice :)
