Euporie extremely slow for long outputs (10K+ lines)

[spencer-scw]

I ran a cell that (accidentally) printed out tens of thousands of lines of output, and this immediately slowed Euporie to a crawl. I don't see any options for limiting/trimming output length, and I was forced to open the notebook in another editor to clear the output before I could proceed. Is there a feature or setting that can mitigate this?

Hi - thanks for reporting.

I've made some optimizations which makes euporie a bit more usable with long outputs: it's now still usable with 1,000,000 lines of output in a cell, and with only 100,000 lines I experience no slow-down.

I've also added a new setting called text_output_limit, which can be used to limit the amount of text output which is displayed. I've set the default to 1,000,000 characters (I'll see how this goes).

These changes are in the dev branch for now. If you want to try it out, you can use uv to test without installing by running the following:

uvx --from git+https://github.com/joouha/euporie.git@dev euporie-notebook --text-output-limit=10 my-notebook.ipynb

I hope that helps!
