Why is my Git Submodule HEAD detached from master?
I am using Git submodules. After pulling changes from server, many times my submodule head gets detached from master branch.
Why does it happen?
I have to always do:
git branch
git checkout mas...

you can give

Introduction - Go Lang Practical Programming Tutorial p.1
Hello and welcome to a Go Language programming tutorial. In this series, we're going to cover setting up and the basics of using Go in a practical way. Go is a programming language where you could easily run through the basics, and then be totally lost when…
os.Rename in goLang?Function signature:
func Rename(oldpath, newpath string) error
What
Rename does?Rename renames (moves) oldpath to newpath. If newpath already exists and is not a directory, Rename replaces it. OS-specific restrictions may apply when oldpath and newpath are in different directories. If there is an error, it will be of type *LinkError.#golang #go #os #rename #os_rename
🛑 Guys from now on you may hear more about
Golang than Python for few months ahead. :)As you may already know in
In golang you need to use
#python #golang #go #fmt #sprintf #format
Python you can format your string using format as below:file_name = "/root/openvpn/{}.ovpn".format(my_file_name)
// Or
file_name = "/root/openvpn/%s.ovpn" % my_file_nameIn golang you need to use
Sprintf method of fmt package like follow:var fileName = fmt.Sprintf("/root/openvpn/%s.ovpn", myFileName)#python #golang #go #fmt #sprintf #format
Echo: High performance, minimalist Go web framework - https://echo.labstack.com
- https://github.com/labstack/echo
A sample hello-world web server using
Echo:package main
import (
"net/http"
"github.com/labstack/echo/v4"
"github.com/labstack/echo/v4/middleware"
)
func main() {
// Echo instance
e := echo.New()
// Middleware
e.Use(middleware.Logger())
e.Use(middleware.Recover())
// Routes
e.GET("/", hello)
// Start server
e.Logger.Fatal(e.Start(":1323"))
}
// Handler
func hello(c echo.Context) error {
return c.String(http.StatusOK, "Hello, World!")
}
environments in
To set a key/value pair, use
Use
#golang #go #env #environment #environment_variables #range #setenv #getenv #environ
Golang:To set a key/value pair, use
os.Setenv. To get a value for a key, use os.Getenv. This will return an empty string if the key isn’t present in the environment.Use
os.Environ to list all key/value pairs in the environment. This returns a slice of strings in the form KEY=value. You can strings.Split them to get the key and value. Here we print all the keys:package main
import (
"os"
"strings"
"fmt"
)
func main() {
os.Setenv("FOO", "1")
fmt.Println("FOO:", os.Getenv("FOO"))
fmt.Println("BAR:", os.Getenv("BAR"))
fmt.Println()
for _, e := range os.Environ() {
pair := strings.Split(e, "=")
fmt.Println(pair[0])
}
}
#golang #go #env #environment #environment_variables #range #setenv #getenv #environ
If you want to implement "Python Capitalize" method in
There is another method called ToTitle which is used for one character long (but to letters):
#python #golang #go #ToLower #Title #strings #capitalize #ToTitle
Go:strings.Title(strings.ToLower("MYNAME")) // output: MynameThere is another method called ToTitle which is used for one character long (but to letters):
str := "dz"
fmt.Println(strings.ToTitle(str)) // output: Dz
#python #golang #go #ToLower #Title #strings #capitalize #ToTitle
drop by drop and your bucket gets filled upیکی از اساتید جمله بالارو مطرح کرده بودند که به نظر من میتونه زندگی بعضی هارو متحول کنه! موضوع بحث اینه که شما قطره قطره به یادگیری خودتان اضافه کنید و در این امر ممارست به خرج بدید و برنامه ریزی مدون داشته باشید. شک نکنید، شک نکنید که به مقصود خودتان خواهید رسید. اگر بخواهیم در کانتکست برنامه نویسی صحبت کنیم یک زبان جدید را در نظر بگیرید که قرار است فرابگیرید. چطور میتوانید یک زبان جدید را مثل زبانی که الان به آن مسلط هستید یاد بگیرید؟ آیا باید زندگی را تعطیل کنید و مسئله جدید را یاد بگیرید؟ نه اصلا اینگونه نیست، تنها کافیست بصورت قطره چکانی هر روز به آن مبحث بپردازید. فقط کافیست هر روز نهال نو پا را آب دهید و به آن برسید این درخت قرار نیست یک روزه تنومند شود و یکروزه میوه دهد تنها برنامه ریزی، تمرین و ممارست شما را به سر منزل مقصود خواهد رساند. تنها کافیست روزی یک ساعت برای آن وقت بگذارید و آخر سال ببینید به کجا رسیده اید. drop by drop!
