al-ce / opptogg.nvim

Neovim plugin to toggle a word under the cursor to its 'opposite' value

OppTogg

Toggle a word under the cursor to its 'opposite value', e.g. True -> False.

Installation and Setup

With packer:

use({
  "al-ce/opptogg.nvim",
  config = function()
    require('opptogg').setup({
    -- config or leave empty for defaults
    })
    end
})

Usage

Set the cursor over a word in OppTogg's table and execute :OppTogg to substitute its 'opposite'. The cursor remains in its current position. Example (where * denotes cursor position):

Before            | After
------------------|--------------------
if foo == tr*ue:  | if foo == fa*lse:

Configuration

This shows the default configuration. Passing a new table to opp_table will override the default table completely.

No mapping is set by default. Set a mapping for :OppTogg on your own or set a string value in mapping to have the config do it for you.

 require('opptogg').setup({
  opp_table = {
    ["True"]  = "False",
    ["true"]  = "false",
    ["0"]     = "1",
    ["yes"]   = "no",
    ["Yes"]   = "No",
    ["foo"]   = "bar",
    ["var1"]  = "var2",
  },
  mapping = '', -- I use <leader>` since ` toggles upper/lower case.
})

Known Issues

Currently, only words with characters matched by the regex \k can be toggled. This excludes symbols like +-*/=~! and spaces.
