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)

@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.

Anyway to make this case sensitive?

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

Currently, it would seem that instead of using c, you would edit the selection in such a way as to dance around the part you don't want to change with clever use of movement keys. You could also subselect using s, or sub-deselect a part of the selection with alt-K (remove_selections) and edit the rest, if your edit will be symmetrical. Or you can just pipe whatever selection to sed with | (shell_pipe).

For your example, you could do:

• % to select all
• s to select with regex: foo.*bar then <enter>
• s to select with regex: (foo|bar) then <enter>. This selects foo or bar within the selection.
• d to delete selection.

Yes,

• if you have used any capital letters in the query, or
• if you prefixed your query with (?-i)

See #11981

Sweet, thx.

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

And what about find and replace in all project files?

[kirawi]

There was an abandoned PR for this: #4381

However, if you are using an LSP you can use space-r

A vimgrep clone would be great but I think right now there are more important things that need attention in helix. For now sed will do the trick.
