Adding custom behavior for the selected match of consult-line

[ghosty141]

Hey, I'm trying to customize consult-line to integrate into the way I use isearch. I love consult-line as my primary way of searching in a file, what I want now is that when I press "enter" and go to the result, the result gets set as isearch-string.

I looked at the source and I saw that consult--read allows setting a custom keymap (with which I could wrap vertico-exit which seems to be the default). But I don't know how to add that :keymap without copying tons of code.

Any ideas on how I can achieve this?

You can use an after advice and use the current line as isearch-string.

What function would I advice? I thought about vertico-exit but I'm not sure where to get the string from and it should only run during consult-line.

consult-line. You can get the line from the buffer.

Sorry I don't quite follow. I don't want to set the isearch-string on any lookup, only when I press enter (not esc for example).

In the consult-line function I only see one function call of consult--read and I don't know how I would modify that. Annotating the lookup function would not work because I only want this behavior on "enter" aka vertico-exit.

I tried it again today but didn't get any further. I don't know how to differentiate between "vertico-exit" and "abort-minibuffers" only for the consult-line case (if I could do that I could use the history for the search-string). I don't want to use the current line as isearch-string but only the query I used in consult-line if vertico-exit (in my case via RET) happened. Maybe and odd usecase but for me consult-line is my primary search tool and I love it!
