Code Completion Not Appearing (Codelite 1.16.0)

python3xdev commented 2 years ago

Code Completion not working. I have reinstalled, reset my codelite IDE and re-ran the setup wizard, nothing helps. Here is a screenshot of my Workspace Settings > Code Completion and of Plugins > Language Server > Settings > clangd/ctagsd :

Disable ctagsd
Compile your code (assuming it compiles)
Does it work?

Do you have little red arrows from clangd (in the editor margin view)?

python3xdev commented 2 years ago

He is what is looks like after doing that:

eranif commented 2 years ago

where is the build output?

python3xdev commented 2 years ago

eranif commented 2 years ago

can you locate a file name: compile_commands.json on your file system? (should be next your workspace file)
Its time to enable the log: settings -> preferences -> misc -> log verbosity -> Debug And paste here the output for the file: %appdata%\CodeLite\codelite-lsp.log
Verify that clangd is running on your system (CodeLite should start it for you, but some people have anti virus software that blocks such processes)

python3xdev commented 2 years ago

1) Yes, the compile_commands.json is there. 3) I checked my antivirus and nothing is quarantined or blocked. (I use AVG) And its running in Task Manager:

looks like a problem with clangd You can download a different one from the internet and configure it? https://github.com/llvm/llvm-project/releases/tag/llvmorg-14.0.0

Pick the windows one and install it. Once installed change the command line from:

plugins -> language server -> settings -> clangd

Here is the updated path to the new clangd exe

This is what I'm supposed to do, correct? I think I entered the correct path. After clicking Ok and testing it, I still get the following errors:

iirc, clangd creates a cache folder in a folder called .cache/clangd under your workspace folder, what happens if you delete it? (close codelite, delete the folder and try it again)

and no, this is not what is supposed to happen... this message is an error:

received an error message: {"error":{"code":-32001,"message":"invalid AST"},"id":38,"jsonrpc":"2.0"}

eranif commented 2 years ago

If this does not work:

disable clangd
enable ctagsd
from the menu bar: workspace -> parse workspace

python3xdev commented 2 years ago

Nothing worked. I looked through the log file and found these lines, are they of any use?:

Terminate clangd, switch to ctagsd.

ctagsd log is located under %appdata%\ctagsd\ctagsd.log

To set ctagsd debug level:

plugins -> language server -> settings -> ctagsd change the command line from ... --log-level ERR -> ... --log-level DBG

then parse the workspace: main menu bar: workspace -> parse workspace

python3xdev commented 2 years ago

What you told me to do with ctagsd made Code Completion work, so I tried doing the same to the Codelite clangd:

I killed the clangd task in Task Manager and changed the Command Line back to the default C:\Program Files\CodeLite\lsp\clangd.exe. Then I Parsed the Workspace. Now its working, all the settings are the same though. Maybe restarting the clangd task fixed it?

Is the Code Completion supposed to auto complete things like #include <iostream> & return 0;, because its not working with these. (both ways, same results)

eranif commented 2 years ago

Whenever you change a settings in the language server dialog, it is supposed to restart the process. Maybe this was the problem and it failed to restart it...

can you run a small test?

Open task manager and take a note of clangd current PID
Change something in the language server settings dialog (e.g. add a space somewhere)
Click OK
Compare the process ID of the clangd

If the PID is the same, then this was the problem: CodeLite failed to terminate this process

python3xdev commented 2 years ago

The clangd.exe had PID 11492 then after the changes it was 14160.

eranif commented 2 years ago

thanks, i think we can close the discussion - it works now

about your question:

#include // << CC is supposed to show here list of known files to the parser

python3xdev commented 2 years ago

When I type #include ios nothing shows. Do I need to manually update it somehow? Also, shouldn't return be suggested by the CC without any problems? I type retu, and nothing.

Also I set Settings > Code Completion > Minimum chars to type to 1

eranif commented 2 years ago

it should suggest keywords as well check under settings -> code completion

and adjust the number of chars to type to show code completion also, does Ctrl-SPACE helps?

python3xdev commented 2 years ago

CC:

Ctrl + Space works on everything else except #include and return.

python3xdev commented 2 years ago

I guess this is not so important, so this issue can be closed. I am going to open another issue right now about text color scheme.

Edit: I changed back to Error from Debug in Settings > Preferences > Misc > Log and this made the #include and returnCC work. I have no idea why that fixed it, but it did.
