Is there a better way to show file name only when do grep?

[cpcopy]

Currently, I use following configuration. The problem is multline configuration doesn't work anymore and no position information.

        grep = {
            multiline = 1,      -- Display as: PATH:LINE:COL\nTEXT
            formatter = "path.filename_first",
            fzf_opts = {
                ["--with-nth"] = '1,2,4..', -- 1: file icon, 2: file name, 3: file path,
            },
        }

Without writing your own formatter (or a custom picker) you’re limited to playing around with --nth, what you could do is maybe set the delimiter to both utils.nbsp and : and then you’ll be able to extract the positron info as it’s wrapped with :, in any event not optimal.

An example where multiple delimiters are used:

fzf-lua/lua/fzf-lua/defaults.lua

Line 658 in 253c6ff

["--delimiter"] = string.format("[:%s]", utils.nbsp),

Thanks. Just know delimiter can be multiple. But it is still failed if I set:

["--delimiter"] = "[: ]"

The space between filename and path is an en space? I tried to follow the source code set as below

["--delimiter"] = string.format("[:%s]", "\u{2002}")

It doesn't work neither. My lua version is 5.1.

I switched to grep_project. It looks like ["--delimiter"] isn't applied to grep_project. It always use : as delimiter.

grep_project sets the limiter by code so it can ignore the file names and grep only the contents, if you set the delimiter in fzf_opts you can override that.

Using \u{} had an issue (forgot what it was), I therefore used the below instead:

fzf-lua/lua/fzf-lua/utils.lua

Line 65 in 40904ab

M.nbsp = [[\xe2\x80\x82]] -- "\u{2002}"

You’re most likely using LuaJIT but if you’re only Lua 5.1 you’d also need to translate the \x yourself:

fzf-lua/lua/fzf-lua/utils.lua

Lines 67 to 76 in 40904ab

	-- Lua 5.1 compatibility
	if _VERSION and type(_VERSION) == "string" then
	local ver = tonumber(_VERSION:match("%d+.%d+"))
	if ver < 5.2 then
	M.nbsp = M.nbsp:gsub("\\x(%x%x)",
	function(x)
	return string.char(tonumber(x, 16))
	end)
	end
	end

Checked the code and found it can only be overwritten by function input parameters. Thanks.

Yes. I saw the comments. I tried what you suggested before. It doesn't work. Now, I write the function input parameters as below. Unfortunately, it doesn't work neither. File name and path name are still in one subset. I checked the unicode of print out ['--delimiter'] = '[: ]'. The space is already an en space.
If I use the default delimiter configuration(no overwritten from configuration), the file name and file path are correctly separated by space, which only works in live_grep, not grep_project.

local grep_opts = function()
    local rg_opts = "rg_opts = '--type c --column --line-number --no-heading --color=always --smart-case --max-columns=4096 -e',"
    local nbsp = [[\xe2\x80\x82]] -- "\u{2002}"

    if _VERSION and type(_VERSION) == "string" then
        local ver = tonumber(_VERSION:match("%d+.%d+"))
        if ver < 5.2 then
            nbsp = nbsp:gsub("\\x(%x%x)",
            function(x)
                return string.char(tonumber(x, 16))
            end)
        end
    end

    local fzf_opts = string.format("fzf_opts = { ['--delimiter'] = '[:%s]' },", nbsp)
    print(fzf_opts)

    return "{ " .. fzf_opts .. rg_opts .. " }"
end

Just find the code for filename_first formatter. \t is used as delimiter between tail and parent.

 return tail .. "\t" .. parent %s

With configuration as below, I can show file name only.

["--delimiter"] = "[:\t]"

Correct, that’s how I reconstruct the path back to the original in the formatter from.
