Tab completion not working

[still-dreaming-1]

Tab completion is not working for me. I seem to have readline working in my PHP, and I also have the relevant autoloading working. I can't for example use tab completion to complete a method name when typing a method to call. I am using PHP 7.2.16. I am using the latest release of PsySH, 0.9.9.

Can you run \psy\info() and paste the output?

@still-dreaming-1 can you look up https://github.com/bobthecow/psysh/issues/435#issuecomment-387756653 - maybe it's similar?

[still-dreaming-1]

@still-dreaming-1 can you look up #435 (comment) - maybe it's similar?

Hmm, yes I get the same results. So it actually does somewhat work under strange circumstances as you described in that comment, but for many basic use cases it does not work at all.

[Wojciechem]

@still-dreaming-1 I think the root of this problem cannot be found using \psy\info(). I am now "lucky" to be on a machine where I don't have it. Maybe that's some strange locale issue? Maybe some module (or zend module like xdebug) is causing it? Would be neat to trace this IMO-bug :)

[still-dreaming-1]

I guess another way to look at this is, what systems/setups is tab completion known to work well on? Does it work well for anyone with a similar setup (Ubuntu 16.04 and PHP 7.2.19)?

This is still not working for me. I am now on Psysh v0.10.4 on Ubuntu 16.04.6. If I create an object instance of a custom class of mine, and then start typing the code to call a method, partway type out the method name I want to call, and then press tab, nothing happens.

Here is my psyinfo

I do have a config file, but all it does is bootstrap into my project (autoload, etc), it doesn't actually specify any psysh config stuff.
