How to debug non-neovim lua code?

[vatosarmat]

Suppose I have a standalone main.lua with #!/usr/bin/lua which does some smart and tricky suftt and therefore it is complicated and therefore I need a debugger with breakpoints to debug it. How to run main.lua under OSV? Maybe there should be an instruction for that

If you can run your script using the embedded lua debugger ( luajit 2.1 ) just go ahead and invoke run_this() with the script open. If you want to use an external lua interpreter I'm afraid it's currently not possible. Have you looked at lua-debug?

It would perfectly possible for me to implement debugging for non-Neovim code, it's just that I never use it outside Neovim so I didn't build any.

Ok, thanks. Could you hint what are the diffs between .lua.t files and just .lua? and where @annotations in .lua.t come from?

Sure, I'm coding in the lua.t files which in turn generate the lua files using a literate programming plugin called ntangle.nvim. I've coded the past year with it and sticky with it for the moment.

If you want you can install the plugin and it should be ready to use. The docs also explain about the syntax. I would be happy to review any PR.

Hi,
I have luajit 2.1 on my OS, however running run_this() in any non-neovim file gives module 'osv' not found error.

Error Log

It seems this error is similar to #11 , however I'm using default config, not nvim -u ${CONFIG_FILE}.
