Recent problem with panel not updating

[beeb]

Hey! First off, let me say I love this package, it saves me a lot of time and is very well thought out.

Recently, it started a few days ago actually, I am unable to follow the status or progress of the tasks via the "panel" that I open via the "Gulp: Show panel" command. When I start a task, any task, the panel displays Running 'default'... or any task name I want to run, but nothing more.

The tasks are being executed properly, but I don't have a feedback. Before, the result of the tasks would be displayed inside the panel. Now it just stops updating after the initial Running... info.

Any idea why that could be? It it possible I messed something up with a keyboard shortcut at some point... no idea how though.

Thanks!

Thanks a lot for the kind words!

I can't really say what might be causing that but, can you please check the Sublime console for errors (when running a task) ? On the Mac, the command is ^`

You have the same problem running gulp on all of your projects or in a particular one?

In the meantime I'll check using my local gulpfiles, to see if I can reproduce it

Thanks!

Heya, thanks for the quick reply. I'm indeed having an error in the console, see below:

I should add that my gulp tasks run fine through the Terminal.

[nicosantangelo]

Hum that's weird it looks like your .sublime-gulp.cache file is broken. Could you do me two favors?

• Copy here the contents of your .sublime-gulp.cache (removing any sensitive data you don't want to share, of course)
• Run -> Gulp: Delete Cache -> Gulp and see what happens

[beeb]

Of course. I already tried deleting the cache two days ago and it didn't help, but here's the content anyway:

{"/Users/valentin/.../_npm/gulpfile.js":{"sha1":"somehash...","tasks":{"clean":{"name":"clean","dependencies":""},"babel":{"name":"babel","dependencies":""},"deploy":{"name":"deploy","dependencies":"babel"},"watch":{"name":"watch","dependencies":""},"default":{"name":"default","dependencies":"babel deploy"}}}}

Prettified:

{
  "/Users/valentin/.../_npm/gulpfile.js":{
    "sha1":"somehash...",
    "tasks":{
      "clean":{
        "name":"clean",
        "dependencies":""
      },
      "babel":{
        "name":"babel",
        "dependencies":""
      },
      "deploy":{
        "name":"deploy",
        "dependencies":"babel"
      },
      "watch":{
        "name":"watch",
        "dependencies":""
      },
      "default":{
        "name":"default",
        "dependencies":"babel deploy"
      }
    }
  }
}

Here's the error after deleting the cache and launching a task again:

Ok! last but not least (sorry I make you work like this :P )

Could you go to the package folder (which should be on .../Library/Application Support/Sublime Text 3/Packages/Gulp) and check if a .sublime-gulp.cache exists there?

It should contain json data describing your currently running tasks, but for what I can gather, it's either empty or invalid. If I'm right, you'll just have to write [] in it for the package to work

➜  Packages/Gulp git:(master) ✗ pwd                                                       
.../Library/Application Support/Sublime Text 3/Packages/Gulp
➜  Packages/Gulp git:(master) ✗ cat .sublime-gulp.cache
[]

If this fixes the problem, I'll make sure it does not happen again by adding a default value to the file in the odd event that it breaks

[beeb]

Yes, that totally worked!

The file was indeed empty and by adding the empty square brackets everything works again. I wonder what happened that this file was emptied.

Thanks a bunch

[nicosantangelo]

How would I go about doing this?

Don't worry about it! I'll handle it in the code and push a new version later today :). I'll reference this issue on the commit and I'll close it once it's deployed.

Thanks a lot for the report! I really have no idea what might have caused the issue

[beeb]

I realized I misread your comment (thought you were suggesting I should add a default value, because I didn't read the "I'll" haha) and edited my response afterwards, all good :)
