Custom callback if tag is not found

[Opioid]

Is it possible to add an optional, custom callback for cases when no tag is found? For me, this typically happens when I try to look up a local variable and it that case I would find it most useful to simply use swiper or something in the current file.

You could just setup ~/.ctags, add more regular expression to extra local variable.

I didn't think about that. But that would also give me results from different files, right?

I already have a key that does "swiper-at-point", which I use very often to track the usage of local variables in a single file. Admittedly it is a different functionality, but it in my workflow they are closely related, which is why it would feel lika a natural fallback for me personally.

(The idea actually came to me because the counsel-etags-grep fallback never seems to work, although ripgrep is working for other commands in emacs (e.g. projectile). Maybe that is an issue with rg not being in the cygwin folder...)

I would like this too, as this would make it easier to register counsel-etags with smart-jump

See counsel-etags-fallback-grep-function whose default value is counsel-etags-grep
