I've created a go gin app with @nx-go and it's using go version 1.18.5
when I save a file my application stops and asks me to run go mod tidy again, which prevents gow from working properly as my local development environment.
What can I do to fix this situation? It's harder to developed like this.

What is @nx-go? What is gow?

gow:
https://github.com/mitranim/gow
Is a go watch tool
@nx-go:
https://github.com/nx-go/nx-go
it is just a helper to create a go project compatible with nx, which is a build system

I've not heard of either of those, but my guess is you're adding imports and then go wants you to sync up your module.
Since gow is presumably trying to rebuild on file change, it's probably yelling at you then
Generally you would just tidy before a build, but gow is likely trying to build after each save
marble pagoda
maybe gow is able to configure build?
Like enablig it to somehow to run go mod tidy after every build
actually, before
marble pagoda
How so?
muted blaze
I'm guessing the problem is when you add a new dep, so you should be able to just get them before you run gow
Otherwise it might be a general gow issue, I'm not entirely sure

Check this out:
when I run go mod tidy, this happens to my go.mod:
module bnoti
go 1.18
require (
github.com/gin-gonic/gin v1.8.2
github.com/nikoksr/notify v0.38.0
gorm.io/driver/postgres v1.4.6

)

)
then I run my gin App and it runs ok...
But as soon as I save, my go.mod changes to this:
module bnoti
go 1.18
require (
github.com/gin-gonic/gin v1.8.2
github.com/nikoksr/notify v0.38.0
gorm.io/driver/postgres v1.4.6
gorm.io/gorm v1.24.3

require (

github.com/goccy/go-json v0.10.0 // indirect
github.com/mattn/go-isatty v0.0.17 // indirect
github.com/ugorji/go/codec v1.2.8 // indirect
)
And then it stops working

Sounds like something is hijacking your go.mod
Not sure if it's gow, but seems like it might be.
marble pagoda
Actually after further inspection
when I save, generally, without running via gow my go.mod changes
yeah, pretty much I save a .go file and bam, it changes
muted blaze
Seems like something weird is happening with your editor perhaps
marble pagoda
Ok, I removed the go extension from vscode
And I think it works now
yeah, works normally
muted blaze
Might have just needed a restart, sometimes gopls can get out of whack with the editor
editor restart, to clarify
marble pagoda
What does gopls do?
muted blaze
It's the language server, so essentially it's how the editor shows you compilation errors, etc.
marble pagoda
Ok thanks for helping me figure it out.
The problem was that I am using gvm and the vscode extension did not detect the go version I was using
muted blaze
Never had a need for multiple versions of the toolchain 😅
And go can install other versions of itself already.
But yeah, no prob!
marble pagoda
Never had a need for multiple versions of the toolchain 😅
And go can install o...
Really? How can it install other versions?
muted blaze
go install golang.org/dl/gox.y.z@latest
Granted, then you need to call it as gox.y.z instead of just go
But then I've never really needed multiple versions, I just sometimes download tip versions to test new features
marble pagoda
I have a "legacy" system that uses go 1.13 and another new one using 1.16
So gvm allows me to set a default
and I don't have to handle selecting the version
at least handle selecting the version on the execution script alone
but it's interesting to know that, thanks
muted blaze
Fair enough, yeah

Why would one need 1.13 with the backwards compat promise?
