String to ebiten.Key

[mgord9518]

I'm trying to save custom control layouts to a config file, but there seems to be no easy way to convert a string value to ebiten.Key in the API reference so I have no clue how to actually set the keys in game after loading my config.

The opposite is incredibly easy with ebiten.Key.String() and I see keyNameToKeyCode() in the ebiten source, but it's unexported so I can't use it without just duplicating the entire function

Hi,

The problem of converting a string to a key is that it is not obvious how to treat multiple possibility: For KeyEnter, should we accept both enter and return? What about KeyApostrophe (apostrophe vs quote vs ')?

[mgord9518]

Why not just only accept a single value like the ones returned from ebiten.Key.String()? Eg: ebiten.KeyEnter would only be returned from the string "Enter" (non case sensitive) while things like "Return" would return an error

Then a list of valid key strings could be linked in the API guide

#2133 I created an issue for this. Apparently there is a way to handle by yourself. Please take a look at the comment. I'm still thinking whether to introduce a new API.

I just ended up just using the map from their suggestion which works with my needs fairly elegantly, but it does feel like something useful enough to warrant adding an API

OK I've implemented (*Key).UnmarshalText.
