A Neovim plugin that aims to simplify the process of creating LuaSnip Snippets.

## Installation:



`Lazy.nvim` example:



```lua

return {

    "ziontee113/SnippetGenie",

    config = function()

        local genie = require("SnippetGenie")



        genie.setup({

            -- SnippetGenie will use this regex to find the pattern in your snippet file,

            -- and insert the newly generated snippet there.

            regex = [[-\+ Snippets goes here]],

            -- A line that matches this regex looks like:

            ------------------------------------------------ Snippets goes here



            -- this must be configured

            snippets_directory = "/path/to/my/LuaSnip/snippet/folder/",



            -- let's say you're creating a snippet for Lua,

            -- SnippetGenie will look for the file at `/path/to/my/LuaSnip/snippet/folder/lua/generated.lua`

            -- and add the new snippet there.

            file_name = "generated",



            -- SnippetGenie was designed to generate LuaSnip's `fmt()` snippets.

            -- here you can configure the generated snippet's "skeleton" / "template" according to your use case

            snippet_skeleton = [[

s(

    "{trigger}",

    fmt([=[

{body}

]=], {{

        {nodes}

    }})

),

]],

        })



        -- SnippetGenie doesn't map any keys by default.

        -- Here're the suggested mappings:

        vim.keymap.set("x", "", function()

            genie.create_new_snippet_or_add_placeholder()

            vim.cmd("norm! ") -- exit Visual Mode, go back to Normal Mode

        end, {})



        vim.keymap.set("n", "", function()

            genie.finalize_snippet()

        end, {})

    end,

}

```



## Example Usage:



Let's say you want to create a snippet for Lua. We have this example Lua buffer:



```lua

local module = require("module")



local function my_func()

    local x = 10

    local y = 100

end

```



1. Make sure that `/path/to/my/LuaSnip/snippet/folder/lua/generated.lua` file exists with required boilerplate already in place.



For example:



```lua

local ls = require("luasnip")

local s = ls.snippet

local i = ls.insert_node



local snippets = {

  s(

  "my_snippet",

    fmt([=[

Hello {}

]=], { i(1, "World") })

  ),



  ------------------------------------------------------ Snippets goes here

}



local autosnippets = {}



return snippets, autosnippets

```

2. We select the content of the snippet we want to create. In this example, we `jj` to line 3, use `V` then `G` to

select the entire function. Then we press `` (as we mapped for SnippetGenie) to initiate the snippet creation process,

and send us back to Normal Mode.



3. We navigate to line 3 `my_func`, select it with Visual Mode, and press `` to add a `placeholder`.

Then we go to line 4, select `10`, press `` to add the 2nd placeholder.

Then we go to line 5, select `100`, press `` to add the 3rd placeholder.



4. After we selected our initial snippet content and our placeholders, in Normal Mode, we press `` to finalize the

snippet creation process. You will be prompted to enter the trigger for the snippet, let's enter `testing`.

After entering the trigger, press ``, the snippet will be added to the proper snippet file and will be instantly loaded.



5. Enter the trigger for the snippet you just created to test it out.



The file `/path/to/my/LuaSnip/snippet/folder/lua/generated.lua` should now look something like:



```lua

local ls = require("luasnip")

local s = ls.snippet

local i = ls.insert_node



local snippets = {

    s(

        "my_snippet",

        fmt([=[

            Hello {}

        ]=], { i(1, "World") })

    ),



    s(

        "testing",

        fmt([=[

local function {}()

    local x = {}

    local y = {}

end

        ]=], {

            i(1, "my_func"),

            i(2, "10"),

            i(3, "100"),

        })

    ),



  ------------------------------------------------------ Snippets goes here

}



local autosnippets = {}



return snippets, autosnippets

```
