Need to reinstall the same theme each startup

[Argish42]

This is going to drive me crazy.

pry-theme list

It throws me a blank space. If I try to install a theme, let's say ocean with:

pry-theme install ocean

I get the expected output:

Installing "ocean" from Pry Theme Collection...
Successfully installed "ocean"!

Then, I'm able to use it with pry-theme try ocean.

The problem is whenever I exit from pry, and I enter again, the theme installed is not available:

Cannot find "ocean" amongst themes in /home/argish/.pry/themes

I checked the .pry/themes folder and the ocean file is just there...

Your help is really appreciated.

Hello! :)

What are your Pry and Pry Theme versions? Please, make sure that you have Pry v0.10.0 and Pry Theme v1.1.0.

[Argish42]

I just updated pry-theme to v1.1.0 but I'm still getting the same problem here.

Thanks.

[kyrylo]

Please, show your .pryrc.

[Argish42]

My .pryrc is blank at the moment. Anyway, I tried using pry -f just in case, but no luck again.

[kyrylo]

Okay... Could you try to delete the entire ~/.pryrc/themes directory and reinstall the ocean theme (don't worry, the default themes will be restored automatically).

[Argish42]

Yeah, I tried that too. It throws an error like this one:

Errno::ENOENT: No such file or directory from pry-theme-1.1.0/lib/pry-theme/commands.rb:245:in 'initialize'

So whenever I deleted the themes folder I have to create it manually. I also tried reinstalling both gems and using another shell. I'm starting to be short of more ideas.

Also noticed that there were no default themes on this folder before I removed it.

[kyrylo]

So you are using Ruby 2.1.1 and Pry v0.10.0. Correct?

Do you have any other Pry plugins installed?

[Argish42]

I'm using Ruby 2.1.2 and no, no more plugins installed. I tested with rvm ruby 2.1.1 and 2.0.0 and the same happens.

[kyrylo]

Could you, please, copy-paste everything you tried in order to trigger this error? I just need to collect some more information about this quirk.

I cannot reproduce it whatever I try.

[Argish42]

Well, not too much. I just installed ruby with rvm and then I installed both gems, pry and pry-theme.

I have been trying to isolate the problem and this is what I found:

I'm not loading the default themes, so lots of methods are not working, for example pry-theme current throws an error because it's NIL. I installed 2 custom themes and then everything works, and I mean everything.

But for some reason and this is something I don't understand, when I close the pry session and I start it again, it's not loading the custom installed themes. I have to call the install method each time even If they are already in the local folder, and then it works. So I guess something happens with that method that then allows me to do pry-theme try successfully.

[kyrylo]

The try subcommand changes themes only for the current session. If you want to use a theme, you must set it inside your .pryrc like so: Pry.config.theme = 'ocean'.

Pry Theme has had a similar issue recently, but it should be fixed: #39

[Argish42]

Yeah, I know that. The problem is the only way pry-theme is loading themes to try is installing them first in the current session. That's why I think there's something in the install method that then allows me to try theme.

Otherwise I get this error Cannot find "ocean" amongst themes in /home/argish/.pry/themes so even If I put Pry.config.theme = 'ocean' It doesn't load the theme.

[kyrylo]

Could you, please, try Pry Theme from master? I think I fixed the issue.

[Argish42]

Yes, it works. It works with pry-rescue installed as you mentioned in the commit. But without pry-rescue installed, it doesn't.

[kyrylo]

I just released v1.1.2. Thanks for the collaboration! :)

[Argish42]

No problem. Thank you too for your time.

Cheers

Until this gets fixed in Pry, you can get around it by adding the following to your ~/.pryrc

# ensure hooks have been initialized prior to use (https://github.com/pry/pry/issues/1271)
Pry.config.hooks

# ensure pry-theme hook is added since it might have gotten "lost"
Pry.config.hooks.add_hook(
  :when_started,
  :pry_theme,
  PryTheme::WhenStartedHook.new
)
