Occasionally the extension does'nt working at all

[em1983]

Hi,
I used to work with this extension for a while, but after updating to v0.7.0, I have been having a lot of issues like the ones below. I tried going back to an earlier version to continue, but that version also displayed errors. Occasionally, after a few attempts with various versions, if it starts to work, the next day, after reopening the Vscode, everything starts over and....

[Error - 4:04:36 PM]
The VHDL LS server crashed 5 times in the last 3 minutes. The server will not be restarted. See the output for more information.

Hi,
Could you provide more information about your operating system and / or code you are working with? Unfortunately, the error you describe could have a lot of reasons

[em1983]

Hej Hej
I appreciate your response. I am using a 64-bit / Windows 11 Enterprise system, and every time I close VScode and reopen it, ´
i should try different VHDL_LS versions until it works.
Could it be because it is my working laptop that I had to switch to Windows 11 recently?

[em1983]

Hi again,
This issue persists. I should spend a couple of hours switching between different versions until it starts working because it is not fixed on my end. While this approach does not always work, there are times when it does.

Err:

How are you installing vhdl_ls? Are you using the version bundled through the VSCode extension or did you download the version yourself?

[em1983]

Hi, tnx for your response.
Yes, I'm using the VScode extension to install it. I never tried to download it directly. Could that possibly be a solution?

[Schottkyc137]

Could you do the following, please?
In VSCode, on the project that you use the language server on, go to "Output" (commonly on the bottom of the window, in the same tab group as i.e., Terminal) and choose "VHDL-LS Client" on the pop-down menu on the right. Could you paste the output that you see here?

[em1983]

Here you are:

[Schottkyc137]

If you close VSCode and re-open it, does the message stay the same?

[em1983]

NO, got the error now
When you close and reopen it, start sending failure notifications continuously. the VHDL-LS Clinet OUTPUT message is like this:

Checking for language server executable in c:\Users\EM4489.vscode\extensions\hbohlin.vhdl-ls-0.7.0\server\vhdl_ls
Found version 0.83.1

[Schottkyc137]

And is the error output that you posted everything that you see (I.e., the whole log) Usually, there should be more information concerning the error

[em1983]

When I select VHDL LS I can see all of those crash and failure notifications, but if I select VHDL-LS Client, that is the whole log I have.

From here, I should continue to switch between diff versions until one of them can be enabled.

[em1983]

But why, when it started to work, the version was like: Found version 0.80.0 and after close and reopen changes to: Found version 0.83.1
Is this trying to tell us something?

Can you show me the whole log of the VHDL LS output? I believe that what you have shown is not the entire log, but I might be wrong.

But why, when it started to work, the version was like: Found version 0.80.0 and after close and reopen changes to: Found version 0.83.1 Is this trying to tell us something?

There are two different versions at play:

• The version of the VSCode extension (0.7.0) changes very rarely.
• The version of the language server (aka the backend of the VSCode extension) changes much faster. Therefore, there is an automated way to update the language server (which you have experienced now).

The issue that you are experiencing likely has something to do with the language server version, not the VSCode version

Hej
Sorry for the late response. I don't have access to my work computer during the weekend.

If it works (after many tries and errors), it looks like a short message, but once it's not working, the message in the VHDL-LS client will be very short, but the VHDL-LS tab will have a long message of a panicked message with a lot of not-clear CHAR that I will attach below:
