if-then based on character read

[mcswell]

I've defined a number of macros that would be improved if the macro could tell what the adjacent character (like the character immediately following the cursor, if any) was, and act accordingly. In most cases, if the adjacent character is a newline, do nothing; otherwise (which usually mean the adjacent character is an ASCII space character), delete it. Afaict, there's no way to do this--I think I could read that character (using copy), but there's no way in the keymapper to tell what the character is, nor is there an if-then construct.
Am I right? If so, how difficult would it be to add this? (And, I suppose, how much interest would there be, since if I'm the only one who wants this, it's not worth doing.)

Hi, I don't think that clipboard interpretation belongs in keymapper.
One could write some application or script which interprets the clipboard and then e.g. calls keymapperctl --press Virtual1 or keymapperctl --release Virtual1 depending on the content.

I think I could read that character (using copy)

Yeah, keymapper could copy the adjacent character and call the script with Shift{ArrowRight} Control{C} ArrowLeft $(interpret-clipboard).
Depending on the virtual key state one could activate different mappings. That might work in some contexts.

And $(interpret-clipboard) is not something that currently exists, right?

Yes, that is the name of the application/script one would have to write.
