regex-vars.nvim

allows defining variables which are expanded during search. for example, you could make a :email: variable which you type and automatically expands to an email regex.

it supports incsearch and respects your 'magic', 'ignorecase', 'smartcase', settings.

it also changes the functionality of typing / (or ? if backwards). default functionality is to use previous search if empty or end the search. the new behaviour is to automatically escape these characters. if you wish to use the previous search, you can still leave the search empty or use <c-p>.

setup

local rv = require("regex-vars")

rv.setup({
    [rv.escape(":foo:")] = "bar",
})

usage

with the example config, :foo: is mapped to bar. you can use / or ? to search and :foo: in your search will be replaced with bar.
