find and replace

[BKSalman]

I'm not too good with regex, but is there a way to find and replace using the search("/")?

[A-Walrus]

In Helix the usual way to find and replace is to first select with s then replace with c

edit: originally said r instead of c (r replaces with character, with c you can type whatever you want)

@A-Walrus
how about :%s/foo/bar/gI in vim?

[sebastien-meric]

I'd like to search and replace, keeping part of the original selected string.
e.g. in vim :
%s/foo\(.*)bar/\t\1 >
that should change any fooblablablabar into [tab]blablabla >
I am able to find fooblablablabar using '%s' foo(.*)bar
how can I introduce $1 or \1 after typing 'c' ?
thanks

Admittedly, not originating from either vim or kakoune, this bewildered me a heap. When I finally got it to work, it was like pure magic.

I'm still learning Helix so please correct me if I'm wrong, but a big drawback here is how the cursor moves when selecting the whole file.

Example workflow

1. I have complex string they want to replace every instance of. The string is nontrivial, so I intend to enter it into the search system by reading it. (It may make sense to yank the string itself, but I may want to add regular expressions or other "decorations" to the search.)
2. I hit % to select the whole file.
3. I am forcibly scrolled to the bottom of the file. The string I was going to read has disappeared from my view.

Ideally there would be a way for me to construct the search-and-replace action without changing anything about the file or where I'm at in it. Vim's :%s/foo/bar/g does this naturally; nothing happens until the user enters this and then runs the command.

@rayhem I see what you are talking about. I don't use :%s/foo/bar/g, but rather the less adept solution of substitute.nvim. Which would be :substitute/foo/bar/ {N}. foo is what to search for, bar is what to replace it with, and N is the amount of lines to search for foo.

The only problem is there's no feedback like in vim with gc. You basically have to trust the
multiple cursors or "you" the user to input properly. Not sure if the muliple cursors was the
best approach to this. Probably a better solution would have been to make a dedicated
command or function but why reinvent the wheel when multiple cursors are already
part of it? ...

:%s/Foo/Bar/gc
