The gist seems not to be working. Every time I try to run `tr` inside a jest test I get the following error: E5108: Error executing lua: attempt to index field 'run' (a nil value)

[@ascourter]

Great video! It makes a huge difference to see those test outputs in your editor instead of a separate terminal window.

[@ElijahManor]

Yes it does! Thanks man

[@MrRollhax]

Man, I was struggling to wrap my head around neovim config. Your videos have helped a ton. Thank you for all of these - I'm enjoying coding and tinkering again like I haven't since I was 14.

[@ElijahManor]

YAY, glad my videos have helped some. Glad you are tinkering, I sure love being technical and making things. Thanks for sharing

[@IainSimmons]

This is awesome, been waiting for it for a while. It was certainly worth the wait! Some part of me wished for a happy ending where you fixed the test and everything passed though! 😅

[@ElijahManor]

You and me both! I didn't notice that until way after I recorded things and was well into the editing process. Oh well ;) Leaves some to the imagination I guess ha ha

[@ErmandDurro]

Great content as always. Love it that you included the debugging part as well 😀

[@ElijahManor]

Yay, glad you liked it! And thanks as always for stopping by!

[@macmanuelodumeru3708]

Finally, Awesome as usual 🔥🔥🔥 I wonder what's up next

[@ElijahManor]

As you might have noticed. I might switch things up a bit and try something a bit different, but still in the terminal world. Stay tuned :)

[@crowvampire]

Great tool to debugging, usually I used vimspector until now, I will replaced by this haha, thank you for sharing 👍🏻

man, your videos are so good!! i have no words

[@theherk]

These videos are superb. Very helpful. Instant sub.

[@OrenGriffin-y1x]

Thanks for this video ! i followed the steps one by one and when i debug (nearest) i get a DAP error. "Couldn't connect to localhost:{port} ECONNREFUESD" what am i missing?

[@AngelDuranReynoso]

same problem, any solution?

[@AngelDuranReynoso]

I tried exactly the same nvim configuration in a diff computer, and different project, and now it worked perfectly, tomorrow I will review environment packages versions and project configuration and see what is exactly the issue, stay tuned

[@DimasCyriaco]

same problem here

[@gugahoi]

Thanks for sharing this video, neotest and the jest adapter are great. I was really hoping you'd cover the "watch" mode that neotest has. I have been unable to get that setup with the jest adapter unfortunately but I just feel like it's a superior workflow when you get instant test feedback that runs on save. Theoretically, neotest uses treesitter to work out impacted files and should run tests related to them but alas I have not been able to get it to work myself. Maybe you can give that a shot and if you're successful, a video would be incredibly useful!

[@ElijahManor]

I did have it set up to do watch mode, but as you described it didn't seem to work as I expected it should. It would seem to know when a test was changed, but it would get confused as to which item needed the update. So, I decided to cut that from this video since it wasn't consistent, but yes, it would be nice to figure that out. I haven't yet

Cool vid, hey what is the font you are using on your terminal? cool icons.

[@filipebraganca2558]

Nice way to debug!!! Thanks for sharing

[@ElijahManor]

You bet! Thanks for watching and supporting with repeat visits :)

[@brittager]

Wonderful. Would it possible to also provide the link to the Github repo of the project you're using for the demos? If the project is not confidential. Because when you say "let's go to our ... (tailwind, typescript) project, people might not have a project fitting that requirement, thus making it harder to follow along. Just a suggestion for something to add to the description below the videos. Keep up the magnificent work

[@jtucker87]

Can you do this but for neotest-dotnet? I got it to kind of work for full files but not for running locally. No idea what I'm missing, the docs don't seems to mention anything else I need to add.

[@djbessel]

This really helped me set up debugging in LazyVim, including tests and other node applications I can attach to. I'm still puzzled how to launch Chrome and debug frontend stuff, though. I can't get LazyVim to work with nvim-dap-vscode-js, and I'm wondering why it seems to set up adapters on its own instead of leveraging that plugin.

[@prashanthshetty8337]

Thank you! great video, what font is that you are using?

[@sockthedev4904]

Love your work 💜

[@anjanshomodder6463]

what plugin are you using for running nvim commands? 1:16

[@ElijahManor]

That is the noice plugin github.com/folke/noice.nvim

[@raulvargasmunoz1314]

Is it possible to only use the lazyvim.plugins.extras.test.core without install everything else? Great video btw.

[@oloja__]

nice tips right here. how’d you get the nodejs icon though

[@Light-f5g]

Can you make video for python,c,rust ?

[@brittager]

There are some things I do no understand from the video. What do the following neotest-jest options do? ``` jestCommand = "npm test --", // why do we need the double dash ? jestConfigFile = "custom.jest.config.ts", // where do I find this file? What is it? What if I don't have it? env = { CI = true }, ```

[@Heyy_manuel]

anyone has an issue where the tests in the test explorer are not matching the test results

[@joaomarcos7545]

What is those all? 0:25 I don't have this and can't find anything about it

[@bibblebabl]

Hey! Thanks for the video! Could you please remind what is the best reason to migrate to Neovim? What are the advantages of using it in comparison with VSCode e.g?

[@rodrigomeireles5966]

Major point is it is highly customizable and offers first class support to modal editing. But at the end of the day VSCode has a lot of convenience built around and even an vim motions extension so it comes down to preference.

[@npradeeptha]

Besides modal editing and based keybindings on the home row, one of the major reasons I switched was speed. Neovim is silly fast. It opens up instantly. If it gets into a bad state all it takes is like 2 seconds to close and re-open and ql to open up your last session. VS code on the other hand takes time based on all the plugins you have installed or configured and can get very sluggish if your machine is light on resources.

[@ElijahManor]

Great question. I like the thoughts that TJ put together about developing your own PDE (Personal Development Environment). He has a video describing why one might want to use Neovim when there are plenty of other options around kzbin.info/www/bejne/h365en2eeJ6Jm8k

[@npradeeptha]

@@ElijahManor This is a great reference video I haven't seen before. I am going to bookmark it and share when someone asks this question :)

No problem!

[@trancongminh2628]

I'm really appreciate if there is any a kind of vim typescript nodejs debug config video?

[@andrewc8125]

Wow very nice!!

Thank you! 😊

[@germancho-dev]

hi! could you make a video for setting up lazyvim to use java along with nvim dap? im having a lot of troubles setting it up

[@muhammadaneeqasif572]

sir which font are you using

[@ElijahManor]

I'm a big fan of the JetBrains Mono font!

[@maguilecutty]

This is a GREAT vidoe thanks - anyone know how to set it up for 'side by side' testing where the test file lives next to the component file? would be greatly appreciated thanks!

[@LinuxForLife]

Already use it with Rust, Go and Astro-nvim but can't make it work with jest/typescript ... 😞😞😞

[@LinkEX]

You mean NeoVim, or the LazyVim setup in particular?

[@LinuxForLife]

@@LinkEX I work with Astro-Nvim and it already uses Lazy package. The setup seems OK ( no error reported) but nothing happen whe I use it or it shows "No test found" ...

Elijah, 🚀💪

[@ElijahManor]

Thanks man! Good to see you again :)

[@emko333]

is it possible to do a conditional break point?

[@ElijahManor]

The set_breakpoint method supports an optional condition that you can use... github.com/mfussenegger/nvim-dap/blob/master/doc/dap.txt#L684 You might do something like this... map({ "n", "dbc", ":lua require('dap').set_breakpoint(vim.fn.input('Breakpoint condition: '))" })

[@Petar-...-Nikov]

Great content could you show similar for Rust setup and testing

[@muzzamilraza3793]

Make a video specifically for javascript debugging using node2 debugger

[@brianfiszman3179]

i wish it was that straight forward but the neotest plugin SUCKS. I spent days trying different configurations and I go from one issue to the next. My biggest gripe right now are the false positives. It shows you that the test failed while the logs shows different. I fucking hated it with passion, I understand that its vim and that in a POSIX environment you are supposed to fix it yourself but why cant I just get to enjoy it instead of having to go back to VSCode to get my job done???

[@AbdurrahmanHafez]

Great video it worked with me in .spec.ts files but didn't work for .spec.tsx files .. any advice ?
