nvim-luapad VS plenary.nvim

there is this plugin: https://github.com/rafcamlet/nvim-luapad

Ah yes, finally a question I can answer. There is no easy way to do this. This was the first big problem when I started working on: luapad, and I dealt with it, by creating a temporary files, attaching lsp to them, and removed them right away from the file system. But later on it started to cause some problems (can't remember what they were now) so ultimately the temp files are not deleting until neovim is restarted.

I was wondering how the hell you did it. There are no autocmds for window resizing. I was trying to figure this out for preview win for nvim-luapad and I gave up. But this timer idea... aren't there any performances issues?

This is a work in progress, but for 'mini.indentscope' I currently settled on using 'plenary.nvim' with helper for creating full child Neovim processes and testing directly extmarks (source; original idea is from rafcamlet/nvim-luapad). Eventually I plan to convert these helpers and 'plenary.test_harness' into something like 'mini.testing' (but only after yet another ready but being alpha-tested jumping module 'mini.jump2d' :) ). Hope that'll help now.

Hi! I think I have exactly what you are looking for. Check the spec directory in the luapad dev branch https://github.com/rafcamlet/nvim-luapad/tree/dev/specs. I am using RPC to send instructions to another nvim instance and then check the results, restarting it between each test for clear env. It may be a bit messy, but I'm currently working on extracting this logic to a separated plugin.

Here's the other lua/neovim dev plugin I was thinking of that might help testing smaller portions of your code https://github.com/rafcamlet/nvim-luapad

Dude, I like your plugin, but please: do a gif or a video about what this plugin does (nvim-luapad do this and I know exactly what this plugin does)

we can create a function to open a pop up menu using plenary.popup like this, you need to install neovim plenary if you don't already have it https://github.com/nvim-lua/plenary.nvim

If you are really interested in doing this yourself with loop, you should take a look at either plenary.job or netman.shell (I made the latter) as both are very well documented.

I feel this :( That said, alot of plugins rely on plenary.nvim. Its up to you if you determine this is "non-essential" or not. It will almost certainly be available for you to use already.

The big reason I ask is that reaching out to an external python shell to run commands (disregard the fact that its python running) is going to be much slower than using the in built lua JIT interpreter. Additionally, plenary has a built in curl function so you don't have to "reinvent the wheel".

There is also test harness in nvim-lua/plenary.nvim with a slightly different design, but still usable of course.

I am simply using busted or more specifically vusted which is a wrapper around busted for Neovim. It should be quite straightforward to learn the basics, I would say you mostly need to know these functions: describe, it (these are used to structure your test cases) and assert.are_same (to check for table equality). Some people are also using plenary which is also based on busted.

It's based on nvim-lua-plugin-template, but uses Nix flakes to run plenary.nvim tests.
