Integration for fzf-lua

[fira42073]

I would really appreciate an integration for fzf-lua like for telescope, but till we are there I have created a workaround and wanted to share it here.

local luasnip = require("luasnip")
local fzf_lua = require("fzf-lua")

local function search_snippets()
    -- Get available snippets
    local snippets = luasnip.available()

    -- Flatten the snippets table and prepare entries for fzf-lua
    local entries = {}
    for category, snippet_list in pairs(snippets) do
        if type(snippet_list) == "table" then
            for _, snippet in ipairs(snippet_list) do
                local description = snippet.description[1] or "" -- Extract the first description if available
                local entry = string.format("%s - %s (%s) : %s", snippet.trigger, snippet.name, category, description)
                table.insert(entries, entry)
            end
        end
    end

    -- Use fzf-lua to search through snippets
    fzf_lua.fzf_exec(entries, {
        prompt = "Select Snippet> ",
        actions = {
            ["default"] = function(selected)
                if #selected > 0 then
                    -- Extract the trigger from the selected entry
                    local trigger = selected[1]:match("^(.-)%s+-")

                    -- Insert the trigger into the current buffer and go into insert mode
                    vim.api.nvim_put({ trigger }, "c", true, true)
                    vim.api.nvim_feedkeys(vim.api.nvim_replace_termcodes("<Esc>i", true, true, true), "n", true)
                end
            end,
        },
    })
end

vim.keymap.set("n", "<leader>fs", search_snippets, { desc = "FZF search snippets" })
