Custom Lua Snippet Not working

[shihabkhan1]

Hi all
I have a custom snippet for pandoc beamer titles at ~/.config/nvim/lua/snippets as shown below,

local s = ls.snippet            -- Shortcut for snippet
local t = ls.text_node          -- Shortcut for text_node
local i = ls.insert_node        -- Shortcut for insert_node

-- Pandoc Beamer title configuration
ls.add_snippets("markdown", {
    s("pdbeamerconf", {
        t("---"),
        t({ "", "title:  " }), i(1, "Presentation Title"),
        t({ "", "subtitle: " }), i(2, "Presentation Subtitle"),
        t({ "", "author: " }),
        t({ "", "- Dr Shihab Khan" }),
        t({ "", "description: |" }),
        t({ "", "    " }), i(3, "Detailed description of the presentation"),
        t({ "", "aspectratio: 169" }),
        t({ "", 'institute: "My institute"' }),
        t({ "", 'theme: "metropolis"' }),
        t({ "", 'fonttheme: "default"' }),
        t({ "", "fontsize: 11pt" }),
        t({ "", "urlcolor: red" }),
        t({ "", "linkstyle: bold" }),
        t({ "", 'logo: ' }), i(4, "path/to/logo"),
        t({ "", "date: 01/10/2024" }),
        t({ "", "section-titles: true" }),
        t({ "", "toc: true" }),
        t({ "", "---" }),
        i(0)
    }),
})

I also have a lusnip config file located at ~/.config/nvim/lua/plugins/luasnip.lua with,

-- ~/.config/nvim/lua/plugins/luasnip.lua
return {
  {
    "L3MON4D3/LuaSnip",
    dependencies = {
      "rafamadriz/friendly-snippets",
      config = function()
        require("luasnip.loaders.from_vscode").lazy_load()
        require("luasnip.loaders.from_lua").lazy_load({ paths = "~/.config/nvim/lua/snippets" })
      end,
    },
  },
}

However, I cannot see any snippet whenever I type pdbeamerconf.

Can you please help me figure out what is wrong?

Hi All, would appreciate any help on this matter. Thanks

Your luasnip config seems correct. First start with a simple snippet. Create file /lua/snippets/all.lua with the contents

return {
  s("trig", t("loaded!!")),
}

Can you trigger this snippet by typing trig?

[shihabkhan1]

Thanks a lot for your comment. Yes it works. I can see it with trig.

I created another snippet in /lua/snippets/pandoc.lua as below but this one doesn't work.

ls.add_snippets("all", {
  s("hello", {
    t('print("hello world")'),
  }),
})

I tried giving a full path to snippets in the lua/plugins/luasnip.lua file but that also doesn't work:

return {
  {
    "L3MON4D3/LuaSnip",
    dependencies = {
      "rafamadriz/friendly-snippets",
      config = function()
        require("luasnip.loaders.from_vscode").lazy_load()
        require("luasnip.loaders.from_lua").lazy_load({
          paths = { "/home/shihab/.config/nvim/lua/snippets" },
        })
      end,
    },
  },
}

Do I need to wrap the contents inside my lua/snippets/pandoc.lua into a return function?

local ls = require("luasnip") -- Load LuaSnip
local s = ls.snippet -- Shortcut for snippet
local t = ls.text_node -- Shortcut for text_node
local i = ls.insert_node -- Shortcut for insert_node

-- Pandoc Beamer title configuration
ls.add_snippets("all", {
  s("pdbeamerconf", {
    t("---"),
    t({ "", "title:  " }),
    i(1, "Presentation Title"),
    t({ "", "subtitle: " }),
    i(2, "Presentation Subtitle"),
    t({ "", "author: " }),
    t({ "", "- Dr Shihab Khan" }),
    t({ "", "description: |" }),
    t({ "", "    " }),
    i(3, "Detailed description of the presentation"),
    t({ "", "aspectratio: 169" }),
    t({ "", "institute: My institute" }),
    t({ "", "theme: metropolis" }),
    t({ "", 'fonttheme: "default"' }),
    t({ "", "fontsize: 11pt" }),
    t({ "", "urlcolor: red" }),
    t({ "", "linkstyle: bold" }),
    t({ "", "logo: " }),
    i(4, "path/to/logo"),
    t({ "", "date: 01/10/2024" }),
    t({ "", "section-titles: true" }),
    t({ "", "toc: true" }),
    t({ "", "---" }),
    i(0),
  }),
})

ls.add_snippets("all", {
  s("hello", {
    t('print("hello world")'),
  }),
})

I don't know because I don't use custom snippets that much. You really should read the Luasnip docs. The below works fine for me

return {
  s("trig", t("loaded!!")),
  s("pdbeamerconf", {
    t("---"),
    t({ "", "title:  " }),
    i(1, "Presentation Title"),
    t({ "", "subtitle: " }),
    i(2, "Presentation Subtitle"),
    t({ "", "author: " }),
    t({ "", "- Dr Shihab Khan" }),
    t({ "", "description: |" }),
    t({ "", "    " }),
    i(3, "Detailed description of the presentation"),
    t({ "", "aspectratio: 169" }),
    t({ "", 'institute: "My institute"' }),
    t({ "", 'theme: "metropolis"' }),
    t({ "", 'fonttheme: "default"' }),
    t({ "", "fontsize: 11pt" }),
    t({ "", "urlcolor: red" }),
    t({ "", "linkstyle: bold" }),
    t({ "", "logo: " }),
    i(4, "path/to/logo"),
    t({ "", "date: 01/10/2024" }),
    t({ "", "section-titles: true" }),
    t({ "", "toc: true" }),
    t({ "", "---" }),
    i(0),
  }),
}
