JS_Tern startup problem windows

[Michael Collier]

Hi,

Getting errors starting JS_Tern plugin.
cudatext 1.222.5.0

Code: Select all

Traceback (most recent call last):
  File "C:\Users\user1\Downloads\cudatext-windows-amd64-1.222.5.0\cudatext\py\cuda_tern\__init__.py", line 42, in start
    self.process = subprocess.Popen(
  File "subprocess.py", line 858, in __init__
  File "subprocess.py", line 1327, in _execute_child
FileNotFoundError: [WinError 2] The system cannot find the file specified

cudatext 1.222.5.0
Using Windows10
Node v23.10.0

The popup window says..
Cannot start Tern process.
Make sure Tern.js and Node.js are installed.
(I'm assuming they are the plugin and my nodejs system?)

Have I missed a step somewhere?

Thanks,
Mike

I can investigate it, but first I want to tell: LSP Client plugin is much more modern technology than JS_Tern plugin.
Wiki gives info how to config LSP Client for JS

https://wiki.freepascal.org/CudaText_plugins
23.3 LSP server for JavaScript/ReactJS
23.4 LSP server for TypeScript

consider to switch to LSP Client. I guess 'projects' support in LSP is much better.
if you refuse, I will investigate it.

OK thanks Alexy, I'll try LSP

[main Alexey]

I am thinking to remove JS Tern plugin from AddonManager. many shortcomings compared to LSP: autocompletion exists, but some other LSP features - not. No mouse-hover-tooltip, no LSP settings. Smaller speed (LSP must be faster coz LSP servers are more optimized i think).

[Michael Collier]

LSP is working OK for me on (tested linux & windows), thanks for the information about it.

As for JS Tern, I only installed it because I recognized the name from an older project. I'm happy to stick with LSP. If JS Tern is broken on windows (works for me on linux) then maybe best to remove from cudatext AddOnManager as you say.

Can you suggest any other cudatext plugin that relies on nodejs being installed so I can try it on my windows system? It would be helpful to rule out any nodejs path problems in relation to JS Tern error..

I have folder with all Cud addons from
https://sourceforge.net/projects/cudate ... ddons_all/
In Double Commander, I search for 'Node.js' in *.txt, 'in archives too'.
Found:

plugin:
- Emmet Lite

formatters (for CudaFormatter, read docs at https://wiki.freepascal.org/CudaText_plugins ):
- CSS Comb
- CSS AutoPrefixer
- JavaScript JSON

linters (for CudaLint plugin, docs at https://wiki.freepascal.org/CudaText_plugins ):
- JavaScript using jshint
- JavaScript using eslint
- CoffeeScript using coffee
- CoffeeScript using coffeelint
- CSS using csstree
- CSS using csslint
- Markdown using markdownlint

plugin:
- Emmet Lite

Thanks, I installed Emmet Lite plugin and it works ok, so I guess nodejs can be ruled out as a problem with JS Tern.

[main Alexey]

Difference in JS Tern / Emmet: in Emmet, node module is preinstalled. in Tern, node module must be installed by user.
in formatters&linters listed above, for most of them node-modules must be installed by user, so you may see the same problem.

[main Alexey]

I made the fix in the JS_Tern github-repo here:
https://github.com/cudatext-addons/cuda_tern
it can run the Tern now, on windows. if Tern Node.js module is installed globally.

updated JS_Tern package (zip) is here
https://sourceforge.net/projects/cudate ... s/plugins/
to install it in CudaText: open zip-file via 'File / Open'.

Thanks, will take a look. Something I noticed with the Emmet Lite plugin (windows10)..

MainMenu->Plugins->EmmetLite->Help

the cudatext application crashed (no error message). I tried to make it crash again but can't redo..
