How to configure so that only one signature suggestion shows

[chenyulue]

It's fine to automatically give a signature suggestions when I type a function.

However, in my case, two signature suggestion dialogs are displayed as follows:

Actually, the bottom one shows when I type the function name sum, while the top one shows when I finished typing the parentheses. If I type slowly, the two dialogs show in turn; if i type fast, then the two dialogs shows simultaneously, which really bothers my typing.

I install jupyterlab-lsp according to the installation instruction in the readme.md, choosing pylsp as the language server.

My question is how to configure so that only one signagure suggestion is displayed. Thanks!

Thank you for the report. This looks like a bug that should be fixed - it should only show the signature popover rather than both:

• completer (which includes documentation), and
• signature popover

if i type fast, then the two dialogs shows simultaneously, which really bothers my typing.

This means we do not cancel the completer request properly if it arrives late (after the cursor has moved). Should be possible to fix for the next release.

Sorry about the bad experience!

@krassowski Look forward to the next release!

I ended up implementing a different solution in #671: the signature will show up above (if possible) and the completer will be able to co-exist with the signature. I am also adding highlighting of the current argument and better choice of active signature:
