Go CLI; Help, Docs, and Miscellany

A thread🧵⬇
/1 Go Help
When diving into the #Golang CLI `go help` is your best friend.
It contains very detailed reports of each sub-component in the CLI.
(Think man pages, but just for go)
You can see all top-level options with `go help`, then dive deeper with `go help <topic>`.

/2 Go Doc
This is the go-to tool for exploring the #Golang standard library and other packages.
With Go Doc you can lookup docs for;
* packages
* consts
* funcs
* types
* vars
* structs
* more...
e.g. `go doc net/http.StatusOK` to see HTTP status consts defined in net/http.

/3 Go Get
This is the #Golang package manager. You can use any github (or similar) URL that points to a Go package to download (and install) that package to your system.
e.g. `go get github.com/magefile/mage`
Use this to install dependencies (before modules) and system tools.

/4 Go Environment
#Golang tools frequently depend on the environment variables you set.
You can check or modify these environment variables with `go env`.
I've used this many times to makes sure my proxy settings are correct at work.

/5 Go Generate
#Golang has a built-in way to generate code before compiling it.
When used in conjunction with a package like `github.com/josharian/impl` go generation can be used to stub out entire packages quickly.
Check out `go help generate` for more details.

/6 Go Bug
Ever found a bug in #Golang?
Yeah me neither, but if I do, I can report it directly from the command line with `go bug`.
This will create a github ticket with all your environment details to help the go team debug the issue better.
