Can you restart the LSP or do you have to restart the whole IDE?

[Der schöne Günther 316]

After we had migrated a project from 10.0 Seattle to 10.4 without any issues and it was working great, we have now migrated the next (bigger) project by 95 %. However, we are constantly having trouble with code completion in 10.4.1, it often stops working completely.

 

As code completion appears to be a separate process, we have three "DelphiLSP.exe" living besides the good old "bds.exe". When code completion stops working, I thought terminating these processes would trigger the IDE to restart them. But this doesn't happen.

 

Do I have another option besides completely shutting down the IDE, opening it again, loading the project and navigating to where I just left off?

You would have to ask Embarcadero to confirm, but AFAIK no.  The IDE creates the LSP processes and expects them to stay running, so if they die unexpectedly behind the IDE's back, a restart of the IDE is likely needed.

Then I wonder what the point of outsourcing them into separate processes was.

Maybe a cheap way of prolonging running out of memory for the 32 bit IDE process 😀

 

Oh well...

Also now it's running in separate process and will not bring / or slow / down the IDE. You can use the IDE to edit your code while the LSP processes are doing their jobs.

... look some options on IDE tool:

http://docwiki.embarcadero.com/RADStudio/Sydney/en/Code_Insight_Reference

 

by default LSP is enabled... but

 

Delphi: you can choose the Code Insight Manager from either Classic or Language Server Protocol.Note:

The Code Insight Manager lists all managers registered with the IDE.

Delphi: you can choose the Code Insight Manager from either Classic or Language Server Protocol.

C++: you cannot change the Code Insight Manager. It uses the Classic or LSP automatically for the Classic or Clang compilers.

You can switch to the Classic Code Insight and then back to LSP.

A quick note to anyone looking at this thread. You probably would have figured this out on your own, but, looking at the Task Manager, it appears that when you re-select the LSP on the Options screen, you have to close and re-open any open project for the IDE to re-launch the LSP.

I can confirm that Uwe's solution works. I've been using it for a long time without any problems. The IDE automatically restarts the LSP if/when it dies (apparently they expected it to crash occasionally).

Delphi 12 already has a separate menu item for this unter Tools.

Well, at least they are self-aware. Always an important step toward fixing problems 🙂
