How can I group files together based on a live grep?

[andykais]

Something I do all the time on the command line is use the_silver_searcher command ag <pattern> -l to get me a list of files that have contents that match a particular string. I am hoping there is a way to accomplish something similar in fzf.lua. Currently I only know of fzf_lua.live_grep(), which searches the contents of all files under my directory, but flattens each search entry into a separate line in the fzf window. I instead want to see only one entry per file (I think the preview showing the first result would be fine, though ideally I get some kind of aggregate information on the number of matches found per file.

My config setup is pretty barebones, and I am sure I can just directly plug the ag command in there but I was curious what the 'right' way to do this kind of thing is. Thank you!

-- {{{ ibhagwan/fzf-lua
local fzf_lua = require('fzf-lua')
fzf_lua.setup({'default'})

util.map('n', '<C-p>', function() fzf_lua.files() end)
util.map('n', '<C-a>', function() fzf_lua.live_grep() end)
util.map('n', '<C-S-a>', function() fzf_lua.live_grep({resume = true}) end)
util.map('n', '<C-S-r>', function() fzf_lua.lsp_references() end)

Use live_grep or any other method (LSP) to find the desired files, use alt-q to send the selection to quickfix and use grep_quickfix(or lgrep_quickfix) to search the quickfix.

hmm could you describe what you mean with a short config snippet? If I understand you right, that suggestion sounds like it is meant to generate some output for fzf and then search it again a second time with lgrep_quickfix. I am looking for a way to group output from a command like live_grep. I can probably just finagle the underlying command to give me grouped output if that is the correct way to do this

No config needed, for example start with :FzfLua live_grep, search for a regex, select a few entries and press alt-q (enter works too with the defaults) that will send the selected entries into neovim’s quickfix (if you wanted you can then view which items are in there with :FzfLua quickfix), now run :FzfLua grep_quickfix and only the items selected in the first step are searched.

Note you can go back to historic quickfix lists by using :FzfLua quickfix_stack, you can also open :FzfLua quickfix, and select entries and alt-q again to reduce the quickfix list.

Maybe I misunderstood what you wanted, you can use live_grep with ag, run :lua FzfLua.live_grep({ cmd = "ag -l" }).
