"No Outline Available: There is Likely an Error with the Language Package"

[JosephTLyons]

Description

"No Outline Available: There is Likely an Error with the Language Package," is the message I get with every language that I have ide-language packages for. C#, HTML, Python,.. etc. I haven't been able to use any of the IDE features introduce by installing atom-ide-ui+a language package. Diagnostics, advanced completion, etc. There is no sign of anything working.

Expected Behavior

The feature set to work as described.

Actual Behavior

Same as description.

Versions

• Atom: 1.24.0
• Client OS: macOS 10.13.3
• atom-ide-ui: 0.9.2

If you open Atom's console (cmd-opt-i), do any uncaught exceptions or rejections appear?

[hansonw]

Given that autocompletion also isn't working for you, this seems like a deeper problem - atom-ide-ui is not responsible for providing autocompletion results. Only the ide- language packages are (via atom-languageclient.)

[JosephTLyons]

I have the basic autocompletions that existed before installing atom-ide-ui, but nothing new on top of that (to my knowledge at least).

Here's a screenshot of the console after freshly opening Atom and running the command to show the outline of a sample HTML doc and the ide-html package

Hi @JosephTLyons can you try turning on debugging and see what messages you get?

atom.config.set('core.debugLSP', true);

and then restart Atom. You should see more detail then in the dev tools window.

I'm going to close the issue here as it's not atom-ide-ui going wrong here - it's either ide-html or atom-languageclient or atom but we may as well continue the discussion here.

[JosephTLyons]

Made that boolean for debug true, closed Atom and reopened, then ran the outline command. I don't see very many new details however. And just to reiterate, I have this issue with all ide-language packages, not just HTML. I just used HTML for this specific example, but the same happens in IDE-Python, IDE-CSharp, etc. So I assume its not a language-specific issue, but something that is common amongst them all (not very specific, but this is out of my scope of knowledge).

[damieng]

Ah, do you have tree-sitter experimental support enabled?

[JosephTLyons]

Not that I'm aware of. I'm on Atom 1.24.0 and that new tree-sitter isn't included until Atom 1.25.0 (beta) to my knowledge. I double-checked and there is no such setting on my end in 1.24.0

[damieng]

Can you try pressing ctrl-; in the html editor and paste here a screenshot of the 'scopes at cursor' that comes up?

[JosephTLyons]

Hmmm, pressing control + ; while my cursor is in the HTML doc does nothing on my end, maybe I'm doing something incorrectly? I'm really wanting to help resolve this, because there is a group of us that ran into this same issue. Thank you for trying to help troubleshoot this.

[hansonw]

On Mac OS I believe it's cmd-opt-P.

[skylize]

OS-agnostic. Open the file-in-question. While that tab is active, open dev tools, and paste this in the console.

atom.workspace.getActiveTextEditor().getLastCursor().getScopeDescriptor().getScopesArray()

[JosephTLyons]

Thanks, here it is!

[JosephTLyons]

Would anyone else have any helpful tips? Sort of at a loss for what to try next or if it will have to a code fix down the line.

[damieng]

I'm at a loss to explain why it isn't working on your machine.

[JosephTLyons]

@damieng , that's ok. I really appreciate you trying to help me. I suppose will just keep all aspects of Atom IDE disabled and check into it whenever an update comes up. Thanks again.

[JosephTLyons]

Interesting, I disabled and re-enabled the atom-ide-ui package and received a handful of a errors:

Although I wasn't presented with the same errors when deleting and re-installing the package. Strange.

@damieng

Ah, do you have tree-sitter experimental support enabled? (#177 (comment))

Just curious, why would enabling tree-sitter cause a problem here?

[chibicode]

Ah, it seems that the scope changes with tree-sitter.

AtomLinter/linter-eslint#1076
AtomLinter/linter-eslint#1115
atom/ide-typescript@8edda74

[damieng]

Yes, the scope names change with tree-sitter and packages need to update. Looks like the AtomLinter update should be out soon.

[JosephTLyons]

I just updated to the newest Atom with tree-sitter, but It’s been turned off the entire time.

[diramazioni]

I had the same problem (on linux) and the real issue was that I need to
pip install 'python-language-server[all]'

[JosephTLyons]

As an update, IDE is working for me more now than before. Before, nothing worked in any languages. Now, ide-rust works perfectly (diagnostics and outline view and such) and ide-csharp seems to be catching syntax errors and such, still no outline view, but progress it seems.
