Debugging cookbook entry

[theofidry]

As of now there is How to Optimize your Development Environment for Debugging as a cookbook entry for debugging. But what do you think of pushing that a bit further? For example we could talk about:

• The VarDumper component: I wouldn't expect a lengthy explanation on it, but at least mentioning it, showing an example and providing a link to the doc
• How to debug step by step with XDebug: maybe a bit more tricky as can depend of the IDE. So not sure of how to push that but but maybe mentioning it would be enough with links as to how to set it up.
• Useful Symfony commands helpful for debugging: how to list all the routes, the container services, parameters...
• A word of REPL with PsySH and its Symfony integration PsyshBundle

In short, without pretending to cover everything about debugging, I would find it nice to have an entry listing some tools available for debugging.

👍 For adding a quick example of VarDumper and mentioning Psysh (never heard about it, but it seems really cool).
👍 For adding a list of Symfony debug commands
👎 For documenting xDebug, we can mention it but the usage (step by step) tutorial should be done by xDebug documentation.

I fully agree with @wouterj.

Thank you for this issue.
There has not been a lot of activity here for a while. Has this been resolved?

Just a quick reminder to make a comment on this. If I don't hear anything I'll close this.

Unfortunately, the debug guide was removed from the documentation. If we find a relevant place to mention psysh I'm all-in, but let's close for now.
