whop.nvim

This is a NeoVim tribute to the amazing Mac app - Boop.

This plugin uses Telescope or vim.ui.select() to pick commands. Then it uses entire buffer content as an input to the chosen command. After running the command, the buffer content is replaced with the result of the command.

Here is a demo:

Here is what this plugin can do:

• Encode and decode base64, base32, url params, html
• Format and minify json
• Hashing (md5, sha1, sha256, sha512)
• Common strings manipulation (rever, remove whitespace, case change)
• Large files manipulation (join lines, wrap each line with single and double quotes, remove duplicate lines)
• Encryption (ansible value)
• and more (see BUILTINS.md and builtin.lua)

Installation

• install biozz/whop.nvim with your favourite package manager
• configure with require('whop').setup({}) (see Custom commands below)

Now you have three options to start using it:

• Telescope extension
• vim.ui.select()
• :Whop command

Telescope

• load Telescope extension telescope.load_extension("whop")
• use :Telescope whop to open the commands picker

Here is an all-in-one example using Lazy:

{
  "nvim-telescope/telescope.nvim",
  dependencies = {
    { 
      "biozz/whop.nvim",
      config = function()
        require("whop").setup({})
      end
    }
  },
  config = function()
    local telescope = require("telescope")
    telescope.setup({
      -- other config options
      extensions = {
        whop = {
          preview_buffer_line_limit = 1000, -- default is 1000
        }
      }
    })
    telescope.load_extension("whop")
    vim.keymap.set("n", "<leader>tw", ":Telescope whop<CR>", { noremap = true, desc = "whop.nvim (telescope)" })
  end
}

Telescope command preview

Telescope command picker has an additional feature – command preview. Preview allows you to see what the command would do without applying it to the buffer.

For the preview to work properly you need to make sure that:

• your command has preview = true in the definition
• your buffer is not more than preview_buffer_line_limit lines

Most of the builtin commands have preview enabled. By default the preview is disabled for all new commands.

vim.ui.select()

The select function is available in require('whop').select().

You can either set keymap option in the setup function or provide you own vim.keyamp.set:

{
  "biozz/whop.nvim",
  config = function()
    local whop = require("whop")
    whop.setup({
      keymap = "<leader>ww"
    })
    -- vim.keymap.set("n", "<leader>ww", function()
    --   whop.select()
    -- end, { noremap = true, desc = "whop.nvim" })
  end
}

Custom commands

The setup function has commands option, which is a list of objects, containing name and cmd.

cmd can be either string or Lua function. If it is a string, it will be passed to vim.cmd and executed as if you typed : (colon), the value of the cmd and hit enter. If it is a function, it will be called when picked. Functions have an additional benefit – arguments. You can specify the inputs and they will be passed into the function for further customization. This can be useful for transformations, which require additional parameters, ex. Caesar Cipher offset.

Here is a full example:

{
  "biozz/whop.nvim",
  config = function()
    require("whop").setup({
      commands = {
        {
          name = "My command",
          cmd = [[%!my_command]],
          preview = true, -- see "Telescope command preview"
        },
        {
          name = "My other command",
          inputs = { { prompt = "Arg1:", dest = "arg1" }  }
          cmd = function(args)
            -- args['arg1']
            vim.cmd('%s/ //g')
          end,
        }
      }
    })
  end,
}
