Hello! 👋 Thanks for opening your first pull request here! ❤️ We will try to get back to you soon. 🚴

@larsoner do you think it is worth adding a tiny ASCII test file with a button press event in it, to https://github.com/mne-tools/mne-testing-data ?

@WouterKroot , if Eric says yes - would you be willing to provide such a tiny test file? (can be 1-second of data similar to this one

Or even better than adding a whole new file, take an existing file, copy to temp dir in a test while modifying it to add a button line / lines, then use that. That way we don't need to update our test dataset for a single new data line

@WouterKroot we have a function in the EyeLink test suite that does a bit of @larsoner describes, here, Is this something that you can try to add simulated BUTTON events to?

Admittedly, the logic of the linked function is a little hairy since it requires a good understanding of EyeLinks ASCII file specification.. So let me know if you need help. I'm unfortunately running low on availability these days, but happy to help as much as I am able to.

[WouterKroot]

Sure,I will take a look at it. In any case I do have Eyelink files with Button events in it, so I could just copy such an event and add it to a temporary file for testing.

I’ll let you know if I need some help, thanks!

@scott-huberty ngl, git is super nice if you know what you are doing. I apperently have no clue. Unfortunately cannot spend any more time on this right now to get the history right. Some of our previous messages were deleted, but If you want to have a call sometime I would be interested. The button presses simulation and tests work now, but I think debugging some of the column naming functions would be helpful. Good thing is that I am learning along the way.
