keygen VS keyboard-layout-analyzer

I used one of the forks of xsznix's optimizer (I believe it was Tretygon/keygen) which adds a useful "SWAPPABLE_MAP" configuration that specifies which key positions the simulated annealing is allowed to change. I used this to freeze j and k in their Dvorak positions while optimizing the rest of the keys.

I've had a hard time finding tools that let me analyze what keys I use most often. I've found https://github.com/Tretygon/keygen and http://mkweb.bcgsc.ca/carpalx/ thanks to this sub, but they both don't claim to analyze special characters, which are important to me as a software developer. Are there any off-the-shelf tools for analyzing a keyboard layout? I'm not interested in writing my own keylogger. I'm on macOS, for reference. I'd also be curious about Linux tools as well!

if you use a keyboard layout analyzer or evolutionary based generator like (https://github.com/Tretygon/keygen) , to create/analyze keymaps, is that not more based on scientific facts then?

It just moves some keys around laterally (so your Colemak-dh keycaps that are row profile-specific will work if you already have some). Stats from Keyboard Analyzer are shown below (Changed key are highlighted in Yellow). I'll note that the mod scores are higher on various tests on https://stevep99.github.io/keyboard-layout-analyzer so I don't foresee many degredations. The most obvious degradation at the time of writing is the bigram WI.

I think you should be able to get good metrics on bépo with layout analyzers (I never checked if this one supports accented characters) : https://stevep99.github.io/keyboard-layout-analyzer/#/main

this (https://github.com/stevep99/keyboard-layout-analyzer) and the whole bunch of parents/forks for analyzing, using the code from repos you work on.
