Go Programming Language¶

Go Language¶

GOROOT="/usr/local/go"
GOPATH="/Users/senthilx/go"

GOPRIVATE=""
GOPROXY="direct"

Go code organization

I set this up in bash profile.

export GOROOT="/usr/local/go"
export GOPATH="/home/senthilx/go"

export GOPRIVATE=""
export GOPROXY="direct"

go install golang.org/x/tools/cmd/goimports@latest

Installed vim-go as the only plugin to work with the default vim. Made sure my ide is working without red lines.

go1.19.1 download
echo "export PATH=~/sdk/go1.19.1/bin:$PATH" >> ~/.bashrc
source ~/.bashrc
go version

How to test go code¶

Write it in play.golang.org
Use this template

package main

import (
    "log"
    "time"
)

func main() {
    date := "7/25/2019 13:45:00" # "7/25/2019 13:45:00"
    timeT, err := time.Parse("1/2/2006 15:04:05", date)

    if err != nil {
        log.Fatalf("Error parsing: %v", err)
    }

    log.Printf("Got: %v", timeT)
}

Modify and Test
Advantages sharable, and no need to create cruft.
