live grep with exclusions

[kapral18]

I am using a lot of live_grep with a lot of exclusions like this

I want to be able to have sets of those exclusions and switch between them while using live_grep

Ideally I'd have a keymap that pops open the picker with prefilled exclusions and puts the cursor right between \b<cursor>\b, so I don't have to go back from end of line to type the live_query

I tried passing search opt to live_grep, but it puts the cursor at the end. Can anybody hint at a right direction here?

Thanks

There are many ways to go about this problem, one way I can think of is crafting your own rg_glob_fn which swaps the args args and query (globs first, query being last) so now you’ll be able to use <globs> … -- <query>.

You can send <C-a>(using feedkeys) in your mapping to send the cursor to the start of line.

Another option is to open grep instead (not live_grep) with an empty search and the glob prefilled and then performing fuzzy search inside the globs only (as if you already pressed ctrl-g):

:lua require'fzf-lua'.grep({ no_esc=true, rg_glob=true, search=' -- *.lua' })

Found your ideal solution using fzf's start event:

:lua require'fzf-lua'.live_grep({
  no_esc=true,
  rg_glob=true, search=[[\b\b -- *.lua]],
  keymap = { fzf = { start = "beginning-of-line+forward-char+forward-char" }}
})

We can also use the "dotted" format for a slightly shorter command:

:lua require'fzf-lua'.live_grep({
  no_esc=true,
  rg_glob=true, search=[[\b\b -- *.lua]],
  ["keymap.fzf.start"] = "beginning-of-line+forward-char+forward-char"
})

For more options to send to fzf, man fzf and search for AVAILABLE ACTIONS:

@ibhagwan well I am trying to achieve what I have in other IDEs already like jetbrains, where you can search multiline by having a selection of lines and searching them across codebase for a match, for example if you want to see if there is an exact duplication of the lines out there.

[ibhagwan]

I don’t understand what is --multiple, there is no such flag, there is rg --multiline and there is fzf’s --multi, there is no connection between these, one tells rg to use multiple lines in the regex and the other dictates fzf to be able to select multiple lines with tab there is no connection between the two.

If there’s a bug open an issue and I’ll fix it otherwise you’re missing something else.

@ibhagwan oh sorry I misworded I meant --multiline, apologies

But as I showed above in the screenshot the multiline works and it lists items matched 1 per line and it works as expected for selection but it fails when action is applied against the selection, so this looks indeed like a bug, I just wanted to double check before opening an issue

One more do I understand it correctly that fzf-lua doesn't support native --multi mode?

@kapral18 i absolutely lost you, I have no idea what you’re asking anymore, please post a single focused snippet of code where you believe there’s a bug and I’ll fix it, make the reproduction complete but minimal and tell me why you think something is a bug and how you believe it should behave.

[kapral18]

@ibhagwan Nevermind about the --multi then.

I am creating an issue right now. Thank you.
