omega.nvim
Lua development utilities for Neovim.
All functions are lazy load.
Install
- lazy.nvim
{"niuiic/omega.nvim", build = "cd rs && cargo build --release"}
Dev
Run current lua file with
require("omega").dofile(vim.api.nvim_buf_get_name(0)). This function would
unload deps of the file before running it, thus you can check the real-time
update of the file without restart neovim.
It's recommended to do unit test with this function and builtin assert. Check
lua/omega/exist_in_file.test.lua for an example.
