LuaSnip-ulid.nvim

Adds a ULID snippet to LuaSnip. Example: 01HWP73EY83X6FAHG3DQKCHJMA

Uses: ahawker/ulid's algorithm for generation (specifically)
See: ulid/javascript for information about ULID

Why?

I quite enjoy the uuid snippet and wanted a ulid one. I find it quite convenient while making dummy data in databases to hardcode those fields, especially after a few database wipes + repopulations. Having it a snippet means it's always at your fingertips!

Requirements

Bash. Must have access to the date command.

I would be open to alternatives. My original starting point for this plugin was Tieske/ulid.lua, and he used ngx.now() and LuaSocket. Both of which are extra dependencies, and thus I stuck to using Bash's Date command. Note: the reason I doesn't using something like os.time() is that command doesn't provide milliseconds, which is required to get a "proper" ulid

Install

• https:/folke/lazy.nvim

{
    "Nealium/LuaSnip-ulid.nvim",
    dependencies = {
        { "L3MON4D3/LuaSnip" },
    },
    config = function()
        require("luasnip-ulid").load_snippets()
    end,
},

Manual

If you instead don't want to add another plugin, I understand, this might be a better route especially if you plan on adding your own custom snippets at some point. I designed this plugin with this in mind.

Note: This would require any additional snippets from you to be "Lua Snippets."See: Lua Snippets for beginners, LuaSnip.DOC.md, or if you're like me and just want to see code, look at LuaSnip-snippets.nvim- their lua/luasnip_snippets/snippets/all.lua is a good place to start.

Copy File

1. Create a dir ~/.config/nvim/lua/snippets
2. Create a file ~/.config/nvim/lua/snippets/ulid.lua
3. Copy contents of lua/luasnip-ulid/ulid.lua and place into the newly created file

Importing

Easy way

Install LuaSnip-snippets.nvim and configure is as the README says. This will auto check that lua/snippets directory and add all snippets in the files.

Hard(er) way

As we don't want extra plugins, adding this block of code will essentially do the same thing, but without all the snippets provided with LuaSnip-snippets.nvim:

{
    "L3MON4D3/LuaSnip",
    -- follow latest release.
    version = "v2.*", -- Replace <CurrentMajor> by the latest released major (first number of latest release)
    -- install jsregexp (optional!).
    build = "make install_jsregexp"
    config = function ()

        -- This Block
        local luasnip = require("luasnip")
        for _, snip_fpath in
            ipairs(
                vim.api.nvim_get_runtime_file("lua/snippets/*.lua", true)
            )
        do
            local snip_mname = snip_fpath:match("^.+/(.+)$"):sub(1, -5)

            local sm = require("snippets." .. snip_mname)

            for ft, snips in pairs(sm) do
                luasnip.add_snippets(ft, snips)
            end
        end
        -- This Block END

    end
}

all props to LuaSnip-snippets.nvim for the block above. I just condensed it and changed it to use add_snippets
