VScode for Golang - How to setup Visual Studio Code for Go [2020]

[@JohnCodes]

NEW UPDATED VERSION OF THIS VIDEO FOR 2022!!!!! ---->> kzbin.info/www/bejne/pqfJdoaJdseVqtU

[@JohnCodes]

Hey all - VScode as of ~Feburary 2021 now enables the gopls server by default and much of the documentation has now moved into the upstream "golang" github org. So this video is a bit out of date. But, there are still some useful tidbits around enabling debugging, some of the settings, etc. Checkout the official repo for more documentation: github.com/golang/vscode-go

[@nagendrapatel7404]

Nice and detailed one. Very helpful.

[@billionairepodcast]

VScode golang extension JSON configuration on gitub is missing. Not on the website anymore

[@JohnCodes]

Right - alot's changed since I made this. Many of the settings have moved out of the "beta" state. Check out the official github for configuration settings: github.com/golang/vscode-go

[@GolangDojo]

I'm reading the doc - it says "VS Code Go extension now enables the gopls language server by default", and it seems we no longer need to do anything!

[@hedobeagamer2340]

That must explain why the page for the JSON settings doesn't exist anymore in the repo

[@JohnCodes]

Excatly!! Alot's changed since I made this. Check the official github for configurations: github.com/golang/vscode-go

[@khazaryahu]

Thanks man this was really useful for setting up vs code for Go.

[@JohnCodes]

Glad it helped!

[@evinwoon6809]

Hey John! Im having problems with inputting in Go on VS code so i thought i didnt set up properly. I can input something, but after i do, i get this error noDebug mode: unable to process 'evaluate' request. Im kinda stuck at 4:24, for one thing, the link you provided doesnt exist anymore, and when i try to manually input the settings in the settings.json tab, it just doesnt work. Please help! Loving your content so far!

[@amrutnikam5643]

I already have visual studio .... So can I directly install the extention for go and run code or Else I have to install first go ? Pl tell..

[@eltirad0]

do you know how to work with microsrvices in golang? what I want to do is open a workspace folder with all my microservices and start working in a simple instance in VS Code instead of having a new VS Code instance for each microservice, I am able to open the workspace but it shows a lot of errors in each .go file in the import sections, I think I need to configure something about go modules (go.mod) in every microservice but I don't know what :(

[@sameeralikhan5133]

whenever i try to update or install gopls extension vs code always gives me the following error could not import debug/elf (EOF)

[@manofqwerty]

Does this still need to be done in the current year?

[@milkyway9225]

what a cute chipmunk. the one with glasses. dude took Gopher impersonation too seriously

[@JohnCodes]

it meee

[@rumpeldrump]

why not use the build-in terminal?

[@pietergleixner3994]

For 2022, install the extension as said and almost everything comes by default. But if you run a hello world it will appear an error like " go.mod file not found in current directory or any parent directory; see 'go help modules' " you fix it in the terminal with the command "go env -w GO111MODULE=off" and thigs should work fine. As for testing, you need to create the launch.json first, the promt as shown in the video doesn't show again. After creating that file that should be automatic then you can run the test as in the video.

[@mikecon4097]

Hi Pieter, can you pls share your launch.json setting file, for me, it's not working, saving files is taking years, the entire system is getting slow on saving, and also your settings.json for go Thank you

[@pietergleixner3994]

@@mikecon4097 Hi, first, I made a major mistake, DO NOT use the command "go env -w GO111MODULE=off" it will ruin future projects. Every project start with "go init mod " the setting JSON file should be auto-generated. Start your project on the main.go (or the main file of your project) with F5 for debugging. If you don't do that it will launch an error to configure the JSON file I mention, you don't want that.

This helped me in 2022. 😁😁

[@kunafeh]

super helpful! wish you channel grows fast. Here's a sub.

[@JohnCodes]

Thank you very much!! Appreciate it

[@Ankit-df8rw]

I installed the same theme...but not able to get the same appearances...can anyone help one plz?

[@AnubhavLatiyan]

bro is there any offline installer for go tools?

[@MrTornnado]

Thank you! My golang intellisense was sooo slow, but you have fixed it

[@JohnCodes]

Awesome!! Glad this was useful!!

[@philip9489]

The Link for "VScode golang extension JSON configuration" is outdated/ unavailable

[@JohnCodes]

Yeah, alot has changed since I made this video. For one, the gopls server is no longer in "beta" so alot of the settings have also changed. Check out the official github for configurations: github.com/golang/vscode-go

[@महात्मा-गांधी-असली-वाले]

sidhi bat no bakawas its mean say straight forward point to point thank bro

[@dylankawalec3517]

I'm getting an error saying " Failed to launch: could not launch process: can not run under Rosetta, check that the installed build of Go is right for your CPU architecture... where it wants me to launch.json ; what do I do? Mac m1 mini with rosetta

[@JohnCodes]

Sounds like you might have the wrong version of Go for your M1 mac. I'm not sure if Go is supported on the new ARM architecture macs.

[@paverschlev98]

Just want to ask is it possible to input when I use vscode debugmod on vscode?

[@JohnCodes]

Hmmmm I'm not sure - I doubt it

[@JohnCodes]

Hey all! Thanks for watching! Hope you enjoy using vscode with golang - let me know what you want to see covered next with Golang!!

[@khazaryahu]

Hi John, I have seen in some websites that Golang is the language of the cloud, Can you do your next video about "how to get started in cloud computing domain using Golang 🤔"

[@JohnCodes]

Great idea! I'll see what I can do!

[@exit-zero]

Great job mate

[@JohnCodes]

Thanks much!

[@jianlu9841]

I was trying to install those extensions and it said "cannot install go tools. set either go.gopath or go.toolsgopath in settings."

[@JohnCodes]

You'll need your go path set. This _should_ get set automatically when you install go on your system. Make sure you have go setup and installed correctly.

[@carlosazurmendi6918]

my go.mod file doesn't have a red go icon

[@JohnCodes]

Hmmmm you might need to get a different icon plugin - there are lots and lots!

[@kayax01]

And what about the workspace? This is the first thing I'm asked from studio... You don't even mention it aut you're presenting a code before defining a workspace?

[@JohnCodes]

Good question! With Visual Studio code, you can open any directory or folder without having to define a workspace. And for Go, you can open some ".go" files and get started without having to get a workspace up and running!

[@जैराधाकृष्ण]

Thanks a lot as short video covering debugging

[@JohnCodes]

You are most welcome!!!

[@CikaVuksan]

How to setup auto run when I save changes?

[@JohnCodes]

There's a setting for that. You want the "go.buildOnSave" setting

[@SarveshBhatnagar1214]

vscode settings link not found. That needs to be upgraded but great video overall.

[@stanislavdimitrenko]

I think you don't need it now. I work without it settings.

[@JohnCodes]

Yes, VScode has moved around some of their repositories. The gopls beta is now more integrated into the plugin. Try this link: github.com/golang/vscode-go

[@damo190]

Hi John, I was thinking to learn NodeJs as I am a frontend React developer. Now I am thinking to get hands-on experience with golang instead of NodeJs. My system has i3 2nd gen processor with 6gb RAM and no external graphics card support. Can I start learning with this laptop? And I want to watch your new video series on golang. I am new to it.

[@JohnCodes]

That laptop should be fine :) but might be a little slow. If you upgraded to an i5, that would be more than enough. Give it a try and see how it works!!

[@cal1686]

gopls doesn't work for me. I get couldn't find import when using vscode for module.

[@JohnCodes]

Hmmmm - interesting, might be worth opening an issue with the vscode go tools. Again, gopls is still in beta so it could be rough around the edges.

[@cal1686]

@@JohnCodes Yeah, good idea. I noticed that I only had the problem when I was using vscode workspaces. It's fine if you just open a folder. Although, I don't know how to confirm it's using gopls vs. the built in.

[@kunafeh]

May I know what software you use to make these videos? Like simultaneous capturing of your screen and video. It's pretty neat!

[@JohnCodes]

Thanks! OBS is what I use

[@sm5172]

Very useful, thank you. You have great presentation skills.

[@JohnCodes]

Thank you! Appreciate that

[@abraaocarvalho4505]

What is the theme of your vscode ? Is beautiful.

[@JohnCodes]

I believe this is one of the "One Dark" themes. I also frequently bounce around the various "Monokai" themes. It's nice since they are so easy to install and switch between

[@parthjoshiastron]

Hey John, Cool video. I couldn't get the definition (F12) thing working, any suggestions?

[@JohnCodes]

Good question - the Gopls server is still in beta, so they definitely have some bugs to iron out. A re-install may do the trick. If you open the command palette and "Go: install tools" you can re-check gopls. Also, make sure that your gopath and your whole go environment is set up correctly. And if you're still running into issues, may be worth opening an issue on github

[@parthjoshiastron]

@@JohnCodes Thanks, will try that.

[@JohnCodes]

@@parthjoshiastron Good luck!

You’re welcome!!

[@diansaputra7575]

Thanks broo!!

[@JohnCodes]

No problem!! My pleasure

[@guents]

Thanks for the content. I think vscode can be nice for a small project, but on a big project you can see some weird behavior. Debugging throws weird exceptions, breakpoints in go routines work randomly (sometimes it stops sometimes it doesn't), watches don't work most of the time, even watching a long string is difficult. When you have many files, suggestions don't work anymore and sometimes you can't even save a file. Overall i think it is difficult to do some serious programming in vscode.

[@JohnCodes]

Yeah I agree. I've actually moved to a mostly vim workflow for speed and efficiency. For really beastly projects I might pull up intelij (especially for kotlin and java projects). But VScode is great for short quick things like JSON / yaml editing

[@georgesmith9178]

What is your favorite IDE for developing in Go?

[@sharpals2227]

Great video

[@JohnCodes]

Thanks much! Appreciate it

[@jimxu1963]

your startup screen of vscode is full of “learning rust” projects… interesting… :)

[@JohnCodes]

...... you caught me LOL

Hey could you share your vscode theme?

[@RP-mo2md]

You are jumping from one subject to another skipping steps.
