vim-prettier VS plugin-ruby

and prettier https://github.com/prettier/vim-prettier

You can still use vimscript plugins in the same way in neovim as you do in vim. In particular there's a specific plugin: https://github.com/prettier/vim-prettier

Prettier (https://github.com/prettier/vim-prettier) seems to work fine on html and javascript files. But when I run :PrettierCli on a lua file it says No parser and no file path given, couldn't infer a parser. I have treesitter installed. I used treesitter's ":TSInstall: lua" and :checkhealth shows a lua parser installed. Not sure what I'm missing or what to do to troubleshoot from here,

Have you looked through the configs for vim-prettier? Maybe exec_cmd_async

auto-formatting - prettier

I have been using vim for much much time now. Everything is going well but every time I want to format my code I got stuck. I have tried many plugins like vim-autoformat which is not formatting correctly (not the major filetypes like JSX, TSX), vim-prettier which is very slow and I have to wait some seconds to get the file formatted correctly, coc-prettier this was my favorite but I shifted to LSP so no usage of this plugin now.

Personally I like to use plugins (prettier/vim-prettier / fatih/vim-go) for added simplicity and less manual configuring (less filetype based configuring etc.).

Vale considerar também o Prettier:

Prettier started out as an opinionated code formatter for JavaScript, but it now supports many other languages, including Ruby. Installing its Ruby plugin is straight forward: add the prettier gem to your Gemfile and then run bundle.

You'd need a prettier plugin for Lua, similar to the ones that exist for php (https://github.com/prettier/plugin-php) and ruby (https://github.com/prettier/plugin-ruby). I'm pretty sure that there isn't one for Lua, but you can try googling it.

Did you try prettier maybe?

To me "stardard" ruby style is style used in the std-lib.

Whilst I can see the benefit of having an AST format code for you, e.g. if can you use it to fix language version changes like positional arguments and keyword arguments in Ruby 3,.0 I worry about how good/bad RuboCop is at formatting.

Last time I tried it, it was indenting in a different way to the std-lib.

At the time I found that prettier-ruby[1] did a much better job. Hopefully that's improved since.

Rubocop has a very nice auto-correct feature to automatically fix many of the warnings it gives, but we've noticed in the past that with line length issues specifically the auto-corrected files can be misformatted. For that reason, we use the Ruby plugin for Prettier to correct line length.
