How to reset history-index on CTRL-R with CTRL-C

[dezza]

Hello.

I've been looking thru ble-bind and the wiki to find a way to reset the cursor in the history entries. After using Ctrl + R the history-index will be decremented and won't reset if you press Ctrl + C. This means if you retrigger Ctrl + R then it will not start from the beginning.

I tried Ctrl + G which should be isearch or nsearch/cancel.

It seems like Ctrl + J or Enter does indeed reset it.

Is it possible to reset the history-index on Ctrl + C ?

Use the following setting:

# blerc

ble-bind -m 'isearch' -f C-c isearch/cancel

---

By default C-g is the key to cancel the search. It reverts the history position to the original one (i.e., the one before starting the incremental search). To find out how to set it up so that C-c behaves the same as C-g, you can first look at the result of ble-bind -m isearch -P (Note that the search by C-r is the incremental search mode (isearch), and the keymap for isearch is named as isearch):

$ ble-bind -m isearch -P
ble-bind -m 'isearch' -f BS isearch/prev
ble-bind -m 'isearch' -f RET isearch/exit
ble-bind -m 'isearch' -f DEL isearch/prev
ble-bind -m 'isearch' -f __defchar__ isearch/self-insert
ble-bind -m 'isearch' -f __default__ isearch/exit-default
ble-bind -m 'isearch' -f __line_limit__ nop
ble-bind -m 'isearch' -f C-RET isearch/accept-line
ble-bind -m 'isearch' -f 'C-?' isearch/prev
ble-bind -m 'isearch' -f C-g isearch/cancel
ble-bind -m 'isearch' -f C-h isearch/prev
ble-bind -m 'isearch' -f C-j isearch/accept-line
ble-bind -m 'isearch' -f C-m isearch/exit
ble-bind -m 'isearch' -f C-r isearch/backward
ble-bind -m 'isearch' -f C-s isearch/forward
ble-bind -m 'isearch' -f 'C-x C-g' isearch/cancel
ble-bind -m 'isearch' -f C-M-g isearch/cancel

Then you'll find the line of C-g. Mimicking that line, you can write the keybinding setting for C-c in your ~/.blerc. You can just replace C-g with C-c.

Hmm, maybe I misunderstood what you meant.

Maybe it is actually unrelated to C-r, but it is related to the behavior of C-c outside the search mode? I think I can change the behavior of C-c (discard-line).

[dezza]

Ah yes, now I see C-g actually works, maybe I was stuck in a state before..

Yes indeed, the idea is to make C-c (discard-line) work as C-g

I fixed the behavior of discard-line in commit 3b2b4b8. @dezza Could you update ble.sh by running ble-update and check the behavior?

For sure I will, friend! Thanks a lot for your help! :)

[dezza]

Tested now. It works as intended :) Thanks again!

[akinomyoga]

@dezza OK! Thanks for checking the behavior!
