I often copy and paste code/text/snippets etc. Now the code completion pops up at the caret after pasting, so when I immediately press “return” to start a new line I accidentally select whatever random thing code completion pics.
This often results in “abs” appearing as that’s the code completion default of a blank line. This is quite disruptive to workflow - who wants a code completion on paste? I don’t think it used to do this.
Please can we disable or have the option to disable? Thanks!
Even more annoying example of this new ultra-keen popup behaviour:
• if you close a text variable with ’ and press return it inserts “%%!” and doesn’t of course give you a new line!
Still happening on 3.4.1_1
I found that the automatic nature of the popup is controlled by “Enable autocompletion” in “Settings > Code Completion”.
However - another odd case where autocomplete shouldn’t appear is when commenting out a line of code: place caret in a line somewhere, press cmd+/ to comment it out, and the blasted popup appears mid-text meaning one is forced to press esc to regain control of the caret. This further trips up if I press esc twice (in frustration) and then the arrow keys (thinking I’m navigating) but actually this compresses notebook table-of-contents structure as I’ve slipped into command mode (even more annoying!).

As in JupyterLab 3.4? That version is ancient!

Yes, someone contributed this option without implementing any heuristics when the autocomplete should or should not be triggered. There is an issue for this: Poor default autocompletion heuristics · Issue #15013 · jupyterlab/jupyterlab · GitHub. It would be amazing if someone contributed a solution. I would personally love working on it but I am currently more focused on putting out fires elsewhere…
A workaround would be installing jupyterlab-lsp which has some sane heuristics included (GitHub - jupyter-lsp/jupyterlab-lsp: Coding assistance for JupyterLab (code navigation + hover suggestions + linters + autocompletion + rename) using Language Server Protocol)
