I think it would be useful if other string methods supported __FlashStringHelper to be able to read directly from PROGMEM.
The methods that maybe should have a PROGMEM option:
- WriteChars
- file_Count
- file_Dir
- file_Erase
- file_Exec
- file_Exists
- file_FindFirst
- file_LoadFunction
- file_LoadImageControl
- file_Open
- file_PlayWAV
- file_PutS
- file_Run
- gfx_Button
- putstr
- writeString
- file_FindFirstRet (only for Filename)
Unfortunately, I can't see a good way of doing this that doesn't involve lots of code duplication. It's more or less what happened for the println/print function. I don't mind writing the code and submitting a PR, I just wanted to get some clarification on whether it's the right approach to duplicate these functions. For all of them but WriteChars, I think they just pass into WriteChars. So the only function that would actually be different is WriteChars itself, every other function would be identical aside from type info.
