Follow along with my neovim dotfiles repo
By far, the biggest challenge was learning Lua 5.1. All the scripting languages I’ve used in the past (Ruby, Perl, Python) emphasize a “batteries included” approach. Lua, in contrast, felt like I had to assemble everything from tiny parts.
Once I got past the Lua hurdle, the rest of the conversion was straightforward. Most of the time I could swap out Vimscript with neovim Lua API methods via a regexp.
I’m pleased with the results. Startup time is faster, there are fewer weird bugs, and I understand all the configurations.
