config demo - run grep on selected files

[vertexE]

I wanted the ability to grep on a subset of files as I felt this was the only picker option I was missing. If anyone else is interested here's the config!

snacks.setup({
    picker = {
        ui_select = true,
        win = {
            input = {
                keys = {
                    ["<c-g>"] = { "grep_selection", mode = { "i", "n" } },
                },
            },
        },
        actions = {
            grep_selection = function(pick)
                local picked = pick:selected({ fallback = false })
                local items = #picked > 0 and picked or pick:items()
                local glob = vim.iter(items)
                    :map(function(item)
                        return item.file
                    end)
                    :totable()
                snacks.picker.grep({ glob = glob })
            end,
        },
    },
})
