[@jankapko9338]

"then i found LuaSnips and my life did a whole three sixty" lmaooo

[@teej_dv]

I was hoping someone would catch this haha

[@thaddaeusmarkle1665]

180 degree turns are for noobs. BeginBot goes all the way.

[@eduardoaranda4379]

This is another level of intro 😄

[@teej_dv]

haha thanks! Trying to raise the bar each time.

[@gomezhyuuga]

Can't express how much I loved the intro!

[@teej_dv]

Wow! That's so generous and kind of you :) thanks so much! I will keep on trying to make people laugh and learn at the same time!

[@luislindgren5615]

What a masterpiece hahaha Learned a lot and laughed hard, 11/10!

[@teej_dv]

Dang, 11/10. Idk how I can keep trying to top that haha! So happy you liked it :)

[@dim-2d]

Bruh, the intro is another level! Excellent video! Keep up the great work, it’s much appreciated!

[@elyezer]

The bar was set very high in this one! Looking forward to to the upcoming ones. Great vid as always! Thank you for the great content.

[@teej_dv]

Uh oh, now the pressure is on!

[@elyezer]

@@teej_dv no pressure :D

[@nguyenthanh1479]

With first 2'30 mins for the intro. Gave me the motivation to watch for the rest of video without skipping any minutes. Keep doing. Good job TJ :)

[@cattohappy9263]

Holy cow, I love that I've found your YT channel. Looking forward for the new episode.

[@teej_dv]

Welcome :) looking forward to making it!

[@luiscarloscorderopena7030]

intro is god level

[@zilizhang3555]

Holy moly truly appreciate the humour and mostly importantly the knowledge

[@goosechaser]

Had no idea you posted this but found it from the LuaSnips documentation. Great video hahaha

[@kylewoock]

This is the best neovim / programming video I have ever seen.

[@robertjmccabe]

Thanks!

[@mohityadav21]

The intro is awesome. Also, nice transitions.

[@teej_dv]

Awesome! We're trying hard to get better each video!

[@nitinmax1000]

Super cool intro Teej! Loved alot and as usual awesome neovim content.

[@ertugrulsrt5761]

breaking change: to set snippets you need to use add_snippets ls.add_snippets('all', { ls.parser.parse_snippet("expand", "als;dfjasldkflasdfj"), }) ls.add_snippets('lua', { ls.parser.parse_snippet('lf', 'local $1 = function($2) $0 end') })

[@ellisonleao]

my day just got a lot better after watching this video

[@teej_dv]

[@craigdanielmaceacher]

Finally taking the dive into setting up luasnip with cmp, the options and config is a bit overwhelming for novice Lua people like myself (long time Vim user though). I'm not a programmer by trade (I'm a tech writer) so someone talking it through like this really helps. One criticism in otherwise great video: the first few characters of the line (check @7:17) are cutoff for some reason.

[@teej_dv]

Thanks! I'll keep that in mind for next time

[@davidsicilia5316]

Thanks for this video, these are so much better than reading through docs

[@mrjson3039]

Just came back to watch this amazing intro.

[@adgai]

Worth the one month waited. Especially the intro. And sorry for the pestering you on Twitch 😂

[@teej_dv]

Haha, it motivated me to keep working on it!

[@willernst]

Oh, man! I don't know if the editing or the grooming is more impressive. I guess I can just say "Amazing cuts!"

[@teej_dv]

ahahahahaha yes, i love it!

[@bl_nkspac_9650]

Underrated comment.

[@julian-fricker]

So much thumbnail, so much hype.

[@astrophilo2000]

that intro is CRAZY !!! love it

[@TG-ll6kf]

It took a whopping 30 seconds for this vid to get my like.. Keep up the great content!!

[@saikoushikmacha7379]

Love the video have been waiting for this from the first episode of this series. Waiting for the next episode hope it comes too soon.

[@Acorn10]

Awesome Billy Mayes impersonation. I'm sold! Placing my order now

[@TheFalloo92]

Strong @ThePrimeagen vibes. Love the energy, love the luasnip.

You lost me at $0 for the last argument. Say whaaaaat??? Great work by the way, keep on rocking!

[@narwashius1176]

Saw thumbnail.... hit that like button !! If my Tuesdays were like this, I hope to contribute nvim sooner.

[@teej_dv]

haha, I hope you liked it even more after watching!

[@benjaminpapin4312]

holly shit this video cracks me up, well done for the content and the energy, keep it up !!

[@teej_dv]

Awesome! Makes me so happy to hear that I'm making people laugh!

[@yttos7358]

Yooo this was exactly what I was looking for!😁 I just started porting all of my `.vim` files to `.lua` and `hrsh7th/cmp` was on that list. Liked and Subbed👍 Can't wait to see the next installment

[@CodeSmell]

🤣 I needed this. At 1.75 speed, the intro is a pretty bangin' rap!

[@teej_dv]

ahaha, I hadn't tried that myself but now I'll need to go back

[@dadinhoschannel4003]

Duuuude! Where is the video two?!! hahah Awesome work, man. keep at it. Best regards

[@teej_dv]

Filming is almost complete. Editing time now :)

[@KronosaurusRex]

Okay, so you were right. I really had to watch this intro. Honestly I can’t even imagine what will you give us next. Btw, hoy do you show the CR and the tabulations? I’m intrigued. And nice video!

[@teej_dv]

Ha! I'm happy you liked it so much! You're looking for ":help listchars"

What a thumbnail ! Can't wait

ITS HAPPENING!!!

You both made my day! :D Superb job! :)

[@orbital1337]

Interesting, I had basically zero clue of how to properly use snippets (I never really used them in any editor) but this got me to try out some things with LuaSnip. The fruit of my labor today is a snippet for Lua development that automatically generates the LuaDoc string for a function. Basically, it uses treesitter to get the parameters of the next function after the cursor and then uses a dynamic node to create a comment like "-- @param p {}" for every every parameter p of the function. Surprisingly this is less than 20 lines of Lua code plus another 10 lines or so for the snippet itself. Neat, and should be easy to generalize to my other main languages!

[@teej_dv]

Talking about awesome code and NOT SHARING A LINK?!?!?!?! :)

[@orbital1337]

@@teej_dv Unless I'm going crazy here, I responded to this comment earlier with a link and I think KZbin automatically deleted it. Or maybe its like flagged for review or something? I don't know how KZbin does things around links these days... This is what I wrote (roughly): I actually just expanded the snippet a bit more - it now also detects whether the function contains a return statement and if so, adds a "-- @return" comment, too. In fact, it checks whether there is a return statement which is not just "return" (i.e. it returns something non-nil), so we don't have false positives for functions that use early returns as control flow. It's on my github at t-troebst/config.nvim/lua/user/snippets/lua.lua (please chill KZbin.. :P). I also had some fun with C++ which is my main language. I wrote some snippets that generate the special member functions (constructor, move assignment, etc.) automatically. They use treesitter to check whether the snippet is being inside of a class or not. If we're inside of a class, we get the name of the class via treesitter and generate the appropriate inline declaration / definition. Otherwise, we use the different syntax to define stuff outside of classes. In that case the use has to enter the name of the class but the templates are still correctly stripped via lua patterns / regex. The code for this stuff is also in the repo (in the snippets/cpp.lua file).

[@teej_dv]

KZbin comments are actually so bad :'( this comment will probably disappear as well

[@orbital1337]

@@teej_dv Yeah like they don't even have the decency to give you an error saying "you can't post links" - they just silently remove the comment after the fact... Anyway, very nice video - it's been fun to toy around with this stuff. :P

Super super video. Thank you so much to learn.

Anyone else having trouble with luasnip recognizing snippets (timestamp 13:28 and 14:37) I found this after reading the docs: ls.add_snippets("all", { ls.parser.parse_snippet("expand", "-- this is what was expanded!"), ls.parser.parse_snippet("lf", "local $1 = function($2) $0 end"), }) Not sure if i'm implementing it wrong or if they changed the method names in a recent commit... but the ls.add_snippets() is what worked to recognize my snippets.

[@kevinjahns2746]

This is awesome

[@hackerzol]

Why make a whole keymap for s when you can do :so and you don't have to make a keymap and its the same number of keystrokes?

[@n0kodoko143]

YES!

[@inzaghinaji1800]

thanks man that was great ^^

Can't remember that I have ever commented on a yt video. But this is hilarious.

Wow! That's high praise! Thanks

[@JusticeHunter]

This is amazing.

[@AndreaSchiavini]

Hey this is great content! I'm loving it :) May I ask what's the colorscheme used here? It doesn't look like the gruvbuddy I see in your dots. Keep up the great work TJ!

[@teej_dv]

Should be gruvbuddy (the picture on gruvbuddy readme is probably just out of date haha)

[@dreimade]

Hey TJ, beautiful vid! I can't seem to get my snippet file to source. Is there a guide somewhere on this? Not sure where you required it or how it's imported into luasnip...

[@teej_dv]

Hmm, just make sure it's somewhere like `plugin/mysnippets.lua` or something like that.

[@BennyPowers]

Loving this. Do neogit and vgit next!

[@teej_dv]

neogit is on the list to explore!

[@robertjmccabe]

Suggestion for a future take Tuesday: in my journey to update my workflow to neovim with modern Lua plugins I am having a rough time getting used to the nvim-tree plugin. I used nerdtree for years and got really used to it 😞. Some of my annoyances: the file explorer window doesn’t resize to fit the file name width. Also, It isn’t easy to easily get a file explorer pane for the current file (it only allows a single nvim-tree pane per window) - I’m used to just doing something like :e % to get a file explorer in the directory of interest. I know these seem like little things but it is throwing off my workflow big time.

[@robertjmccabe]

Nevermind. I went back to the native netrw file explorer. nvim-tree was too weird for me.

[@MegaMario0007]

Stupid question but what do you use for split navigation now then? Could only find etc. in your dots

[@teej_dv]

I'm not sure what you mean. I navigate splits w/ control + hjkl

Hahaha. This was such a good video

[@nyxkrage]

very cool

[@frydac]

damn I made a bunch of luasnip snippets without the extras.. I made my own rep() function after a significant time figuring out how to do this.. I can't believe I missed the extras in the docs (assuming it's there, it is right? EDIT: yes extras is metioned, but fmt() is undocumented for as far as I can see) Also without the fmt() it is not really very readable and quite a bit of punctuation.. and of course I didn't think of creating something like that myself :) And I assume it would be a considerable effort. hopefully vid 2 and 3 will be posted soon Currently using both luasnip and ultisnips as I have to port a bunch of snippets still (which use a fair bit of python I want to get rid of and replace by lua only, it will be glorious!) Thanks for this!

[@teej_dv]

but you learned more things, so that's good :) Working on 2, but it's still a bit away.
