Automatically Execute *Anything* in Nvim

[@gregoryshields4258]

Two years on from the release of this video, I just want to say that although I cannot speak for others, I do know that there is definitely someone (me) who is actually following along with what you are showing, and learning from it, without any forceful expectation of anything further. I've been learning/using Vim, and now Neovim, for about seven years now, and it is truly inspiring to see the dedication and insight you have displayed in helping to bring the Vim code base to new heights. It's very clear that you lead by example, even to the point of Reading the Friendly Manual publicly in its entirety, taking that crude, old acronym and turning it into something a little more positive. Thank you, from one passionate user to another.

[@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!

[@jakeshoemaker1483]

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

[@TheFalloo92]

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

[@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.

[@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 :)

[@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

[@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.

[@driden1987]

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

[@majam1n]

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

[@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!

[@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.

[@gurparv1993]

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

[@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!

[@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!

[@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!

[@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!

[@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.

[@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.

[@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!

[@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.

[@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!

[@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.

[@adriansrfr]

These 10 minute vids are great, keep them coming!

[@connect_to_the_dots]

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

[@vmnog]

waiting for the continuation :) great tutorial !

[@nilsgg]

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

[@davedwad852]

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

[@abohm25]

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

[@yyba2371]

Awsome explanation TJ, Sure we want a another video

[@santiagoosoriosanchez250]

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

[@muhammadsulthanmazaya2388]

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

[@avimehenwal]

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

[@kyleMcBurnett]

This reminds me of mirc scrpting. The mastalgia! Oh! You just sold me in neovim

[@korney4eg]

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

[@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!

[@lucasefe]

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

[@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 !

[@lukasz_kostka]

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

[@Alpha_Dev]

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

[@jpbuilds6167]

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

[@JulianInsua]

Love this kind of stuff!!! Thanks!

[@andredasilva6807]

thats really nice. would love to see more lua scripts

[@СергейЛюбимов-у3ф]

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?

[@jesseleite]

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

[@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 :)

[@DanielTateNZ]

These basics are amazing! More basics!

[@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 .

[@willhleucka821]

Fantastic! Thank you, TJ!

[@IgetsugaS2]

Great content as always!

[@robertjmccabe]

This is awesome. Keep these coming.

[@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 :)

[@mohitkumar-jv2bx]

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

[@armynyus9123]

Best vid on nevim.

[@encode_this1817]

This is great and you should feel great.

[@PhanTanThangTH]

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

[@chrisjames278]

another awesome video, Thanks TJ

[@rickhackro]

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

[@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?

[@vellankiindeevar5530]

its just beautiful

[@dimitardimitrov3421]

WOW, great tutorial!

[@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.

[@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_

[@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.

[@fernandobaroni1497]

Great tutorial!

[@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.

[@bhaveshverma8629]

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

[@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.

[@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 :)

[@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! 😄

[@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 :)

[@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.

[@danilo2735]

Man, that's impressive

[@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?

[@roa234]

Amazing ❤️

[@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

[@adriansrfr]

Wow, very cool!

[@joseduarte9823]

How did you properly set up the Lua NVim API (autocompletion, etc)?

[@teej_dv]

I have sumneko lua lsp + builtin LSP and it should work with those two I think.

[@ricardoislasruiz3186]

Damn beautiful!

[@_zh3ro_]

AMAZING!!!

[@QmVuamFtaW4]

you've got some beautiful hair.

[@scc4213]

really helpful ！

[@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.

[@patersr]

Thanks

[@picosdrivethru]

wowowow

[@kodder]

Good Stuff

[@jazzochannel]

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

[@DragonKidPlaysMC]

More tutorials please!

[@miyalys]

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

[@sp4yke]

which plugin is used for the autocompletion with signature support ?

[@sirisaac8727]

How can we write this in the the new syntax? `autocmd BufRead,BufEnter *.astro set filetype=astro`

[@jithin.johnson]

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

[@ricardorien]

Thanks!

[@greendog105]

hey, I can make things happen upon saving with the "BufWritePost" but I can't make them happen upon opening up a file or Nvim automatically. Wasnt is supposed to work with BufEnter?

[@samiurkhan]

This is it. I will swap from emacs now.

[@zen-ventzi-marinov]

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

[@nodidog]

Top stuff 🥳

[@darkarie]

nice!
