customize keybindings #378

Open antoine-gallix opened 4 years ago

antoine-gallix commented 4 years ago

Is there an easy way to configure keybindings? I cannot find it in the documentation. I'm referring to a way to map key combinations to things like cursor movements, line edition, history.

Yeah, no. It's not even really an issue with ptpython. Like you I desire to give the user the ability to remap the keybindings but they are hardcoded into the prompt-toolkit package using decorators to local functions that can't be accessed outside load_vi_bindings.

However, it should be possible to move these functions to a more global scope, then you can call the remove method for the default key(s) and add in what you want.

Actually, after thinking some consideration you're honestly better off patching load_vi_bindings yourself and installing the package locally. Each binding is an immutable object bound to a private function, so to make the core vi keys "truly" remappable one would have to completely refactor its internals, or write a method that removes the conflict and appends a new one, but that'll engender some headaches for sure. Not worth it.

I'll make myself a colemak patch.

thanks for the update. on my side I've solved the problem with a programmable keyboard, so I just put the standard bindings of every program under my finger once and for all. I only cry a bit when I'm forced to work on my laptop sometimes. I've tried for years to systematically remap all the programs I use into a consistent system, ergonomic and compatible with my exotic keyboard mapping but it's hard work.
