Automatically Execute *Anything* in Nvim

A lot of people asked me in my previous video about Golang "How did you automatically execute the Go code in Neovim on save?" So in this video I'll show you how to do that step-by-step :)
Let me know what you think!

dude - you and prime opened a black hole with neovim for me and i love it bro. thanks for the content

[@no_name4796]

Yeah, he is the reason i was able to get into neovim lol Docs are good, but if they don't give you a more general understanding of how thing work

[@leptanian]

Great content as always. I appreciate these vids that explain bits and pieces of nvim even more after my switch to Lua. Thanks Tj!

[@teej_dv]

Awesome :) hope you're having fun!

[@majam1n]

TJ we're lucky to have you taking us on these awesome Neovim / Lua journeys. Do more, please.

[@abohm25]

Love this!! Great job TJ! I appreciate all the hard work you put into stuff like this. Keep them coming!

[@mischavandenburg]

Thank you so much for this video! I've completely re-done my nvim configuration taking your kickstart.nvim as a starting point and I'm improving my lua to take my customisation to the next level. Please keep making these lua coding walkthroughs, they are a great way to learn!

[@TheFalloo92]

This is precisely what I was looking for, my dear. Great job!

[@nilsgg]

Really enjoy these small practical Neovim Lua examples. Has made it possible to write my own automation functions! Thank you 😊

[@n0kodoko143]

Good the patience you have to walk is through this to this level of granularity, didn't go unnoticed. Sincerely, thank you! Sorry interested in seeing more!

[@alexwexov4298]

Amazing ! I always wondered how to write to buffers or run jobs. This kind of videos that show how to build plugins are great. Thanks.

[@korney4eg]

As always very useful staff and practical examples! Keep going!

[@vahidss]

Thanks. I really needed it. I hadn't gotten in to autocmd so what I did was to have a nodemon (usually in a toggleterm) run what I want to do

[@thaddaeusmarkle1665]

Awesome vid TJ! Would love to see a part 2 (yes I did leave a like 😁), and maybe something like adding the output to the quickfix list if it has a non-zero exit code would be cool too.

[@tobiasweyer5063]

as complete beginner to neovim, this was great to see where the journey of learning neovim, will bring me. :) Thx for the great video.

[@jpbuilds6167]

This is so awesome and well explained. I have so many ideas. Thanks Tj

[@santiagoosoriosanchez250]

Thanks alot I really mean it!. your way to teach is awesome giving ideas and not just how to do a specific thing

[@adriansrfr]

These 10 minute vids are great, keep them coming!

[@vmnog]

waiting for the continuation :) great tutorial !

[@ayoubelmhamdi7920]

This video explains the question I asked in the comments of the previous video, thank you very much

[@Cih2001]

Thanks. Your videos are awesome, and I've learned a lot. Although this is something that people can figure on their own, in the tutorial, it could be helpful to explain how to create a new buffer and open it in a new window for the output using the nvim api.

[@arnaudf.67]

Wow its so much easier and extensible to do these things in lua rather than in vimscript. I remeber back in the days were it was a pain doing something like that neatly when you start having non trivial function. Thanks TJ, and I really looking forward to watch the video you mentioned at the end, on how to attach and detach with command!

[@rsmith31416]

The extensibility shouldn't be any different between the lua and vimscript version. I don't know why you had issues before, but this is the vimscript version that does pretty much the same in 10 lines: let s:bufnr = 4 function Callback(channel, msg) call appendbufline(s:bufnr, '$', a:msg) endfunction augroup GoGroup autocmd! autocmd BufWritePost *.go call deletebufline(bufname(s:bufnr), 1, '$') | \ call job_start(["go", "run", "main.go"], {'callback': function('Callback')} ) augroup END The neovim implementation of jobs is pretty similar.

[@jesseleite]

Love these types of tutorial vids man! Do more of this stuff!

[@JulianInsua]

Love this kind of stuff!!! Thanks!

[@abujessica]

So good at explaining stuff keep it up, truly love these videos

[@teej_dv]

Thank you :) so happy to hear that after posting a video!

[@Alpha_Dev]

Thanks TJ, awesome idea, I will use it soon on my config. Have a great day.

[@yyba2371]

Awsome explanation TJ, Sure we want a another video

[@willhleucka821]

Fantastic! Thank you, TJ!

[@connect_to_the_dots]

Your lesson helped a lot, after that i wrote my first lody. Thank you very much.

[@chrisjames278]

another awesome video, Thanks TJ

[@dimitardimitrov3421]

WOW, great tutorial!

[@user-bs4gg8sq7h]

Thank you very much for such a great content, TJ! Have you considered creating some kind of course on Nvim, explaining and showcasing core concepts?

[@avimehenwal]

amazing amazing, best video on demystifying neovim ever :D Thankyou so much for sharing. Huge like from my side

[@robertjmccabe]

This is awesome. Keep these coming.

[@IgetsugaS2]

Great content as always!

[@muhammadsulthanmazaya2388]

Dang u just become my fav youtuber & streamer! Nice video as always teej

[@davedwad852]

Masterful. You and the other lad always knocking out top notch content. You're Body he's Doyle. Nuff said.

[@DanielTateNZ]

These basics are amazing! More basics!

[@wuilliam321]

Greeeeoeatttttttt! I was trying to do something like this with no success xD. This is great, i just didn't want to store the buffers anywhere, just something temporal. But thanks! Seems to be useful!

[@kristupasqwert9888]

We need more of these. Ive learned so mu ch from watching these! Thanks TJ

[@teej_dv]

I've got a list of things kind of like this that I'm going to try and make it in between some of the larger videos :) glad you liked it !

[@chairlovawitabat]

Thank you TJ! This is so cool. Can you actually do a demo of creating a to-do list using only telescope and the bufwrite api? I think it’d be cool showing how you can create a list of times and then write them programmatically to a local file using lua and the nvim apis. I am playing w the idea of using nvim for latex documents. It’s 90% of the way there. The only thing missing is bibliography management-for me, being able to use a simple UI interface to add/remove refs would easily have NeoVim blow other dedicated editors out of the water .

[@driden1987]

Hi TJ, rewatching this series in 2023, expecting a part 3 !!! Love ya

[@PhanTanThangTH]

Thank you so much, I really really appreciate that :)

[@fernandobaroni1497]

Great tutorial!

[@Hedshodd]

Oh, I could use this to "lua-fy" my current auto commands, which are just calling vimscript inside of my .lua config. Thanks for the video!

[@Ash-qp2yw]

This is actually really cool and I like it. I'm considering doing something similar that opens a buffer automatically and runs a specific linting tool, so I might be able to use some of this - although, I'd want to have it on it's own command, instead of on save, but that can't be too tricky to do

[@lsouza1327]

it's pretty easy to do, just use vim.keymap.set(), just pass the function that you would pass to the autocmd to this function and you are done.

[@wuilliam321]

Yeah! Same here!

[@vellankiindeevar5530]

its just beautiful

[@roa234]

Amazing ❤️

[@Tazato]

Whenever I think my nvim is slick, youtube gives me a video of yours to make it better. Thank you for the tutorial!

[@teej_dv]

That's very high praise! Thanks!

[@_zh3ro_]

AMAZING!!!

[@andredasilva6807]

thats really nice. would love to see more lua scripts

[@kuijaye]

Thanks man!

[@scc4213]

really helpful ！

[@lukasz_kostka]

I'd like to see more of things like this.

[@ricardoislasruiz3186]

Damn beautiful!

[@bhaveshverma8629]

Awesome again learn so much. Thanks you so much....................

[@lalitmee]

Man, I don't need all these other plugins then. It will be simple and useful. You are a wizard, man.

[@teej_dv]

Thanks! :) let me know if you do anything cool with it!

[@lucasefe]

You and prime are rocking it. Thanks. Should we be watching someone else talking about neovim?

[@encode_this1817]

This is great and you should feel great.

[@adriansrfr]

Wow, very cool!

[@armynyus9123]

Best vid on nevim.

[@danilo2735]

Man, that's impressive

[@maheshwarimurli]

Damn this can be super-helpful for running tests for competitive programming

[@teej_dv]

Yeah! Just save the file and BOOM it's running :)

[@mohitkumar-jv2bx]

Lets get this video 1k likes fast!!. And thanks Tj as always for the great video.

[@frydac]

heh, already 1000+ likes within 24 hours, I guess you know what to do. I would be interested to see this maybe in combo with makeprg and errorformat, which I never bothered to try out, as I'm not sure I would like it for C++ with sometimes very long error messages as I would think it gets hard to read when they are in the quickfix window, or even to get the complete error message with errorformat, and I don't know where the stdout goes which also interests me. Currently I use kitty hints to parse the terminal scrollback buffer and neovim remote to open the running nvim instance on the file:line:column of the errormsg. Anyway, great video, never used jobstart, def learned something new again :)

[@nodidog]

Top stuff 🥳

[@kodder]

Good Stuff

[@ricardorien]

Thanks!

[@saltytab]

Thank you for the again another informative video. At the risk of sounding cliched may I asked what is the colorscheme you are using.

[@gamer-tantrik]

Hey Tj love your content as always and a big fan. Why don't we make a cool informative guide to neovim and like setup 3, 4 projects where beginners could learn how to make certain plugins. I think it would really help the community and for interesting people like me who want to contribute to neovim but don't have that much time to go through complete documentation.

[@gurparv1993]

If its Tj video then 2 things in the following order. : 1. Like first, 👍 2. and then watch .

[@steveaguay]

The greatest part of watching others use vim is some simple thing said in the off hand will be revolutionary to me. I had a block where I never thought to use leader twice.

[@darkarie]

nice!

[@picosdrivethru]

wowowow

[@CharlieSmithv2]

Nice vid! Im curious if the same could be done using tmux and a new pane versus a new nvim buffer? Or am i doing it wrong?

[@MrCradleman]

Great video. Finally vim could do something close to Emacs can do since 90-s :)

[@teej_dv]

haha :) well the feature has been around for a lot longer than that, I just find doing it via Lua and Lua autocmds much more elegant. But yes, emacs can do a lot of cool things of course :)

[@artemrusinov3034]

Cool!

[@patersr]

Thanks

[@patriciourrutia2297]

Great video TJ! I'm gona try to use it to compile my md-latex docs with pandoc. The autosave.lua file is located in a special folder or it doesn't matter?

[@teej_dv]

You can put it anywhere you want! You just execute it to turn it on.

[@andrespotapczynski2665]

Hey TJ, where can I put questions and suggestions about topic videos? I'm new to neovim but I want to use some of the ideas that you have shown in the videos for my own use cases.

[@rickhackro]

There's a lot of useful stuff on the nvim_{whatever} API

[@lucastperez]

I do pretty much the same with tmux and a vim plugin called VimTmuxRunner (it sends commands to tmux panes), but the full neovim + lua solution is much cooler! 😄

[@benjinguyen9965]

hey TJ-what colorscheme is that? It's sick!

[@webmandman]

Yo tj, you didn't mention how dynamically create a new buffer and append the stdout lines to it. But I think one can use print(data) which will automatically create a buffer horizontally at the bottom?

[@Zeioth]

I have an autocmd that, every time I write a buffer into the directory "personal-notes" it uses rclone to upload the content of the directory to an online storage service. Then on my phone I have a Termux script "Download notes" to download the same backlog I have on my computer on my phone, and I can read it and edit it on vim. Exactly the same way I would do on my computer.

[@WilmanArambillete]

rookie question: how do you split your screen in panes (you have 3 and have seen you handle your buffers like that in your other videos). Thanks

[@miyalys]

Does vim have an event log to help you see/debug when various events fire exactly?

[@zakariachahboun]

Cool! gopher!

[@WillEhrendreich]

Awesome stuff TJ. How about taking this idea and defeating the enterprise feature for visual studio called live unit testing

[@ChrisCox-wv7oo]

I use fswatch to monitor for any changed files in my project directory, when a file is changed, it recompiles and runs tests. The results aren't tightly integrated with nvim but it does give me real time notification as things break / fixed.

[@WillEhrendreich]

@@ChrisCox-wv7oo I haven't done fswatch, is that similar to dotnet watch? I have done that.

[@webmandman]

dude, I thought I had subscribed to your channel a long time ago. so sorry dude. keep up the great work.

[@teej_dv]

all is forgiven :)

[@VinnyMeller]

How do you get the lsp to recognize the builtin nvim api stuff? e.g you were getting autocomplete when typing vim.api.nvim_

[@KronosaurusRex]

Hello TJ, this is great! Any chance you can explain your tj#saveandexec thing? I find interesting that it sources and kind of reloads neovim. I'm always quitting and opening again.

[@teej_dv]

Well it sources and reloads a particular file -- it doesn't do the whole neovim. I write code that allows things to be re-executed though (and use some knowledge of lua to do so). I will add it to my list to cover reloading nvim from within the same instance though :)

[@sp4yke]

which plugin is used for the autocompletion with signature support ?

[@DragonKidPlaysMC]

More tutorials please!

[@QmVuamFtaW4]

you've got some beautiful hair.

[@thongng5699]

What is the font name you are using?

[@zen-ventzi-marinov]

Hi Tj, I guess you don't use any neovim distribution but if you did, which ones would you seriously consider?

[@jazzochannel]

I'd like to see a follow up to this, please!

[@rajaravivarmar]

How do I set such a cursor in my mac Terminal? I have enabled blinking but I don't know how to set that return symbol.

[@jithin.johnson]

How about using a Makefile and running make command on BufWritePost?

[@murphykuffour6034]

does jobstart support sudo

[@cyprienh2192]

Great video!! Is there a way to clear the buffer?

[@Mankepanke]

I suppose doing the same as the initial example (line 0 to -1) but passing an empty list for the data
