A simple `helloworld` for Golang in VsCode.
|
||
|
||
# Golang the compiler
|
||
|
||
Download Golang [installer](https://go.dev/dl/). A least on Mac the installer shall be able to deal with [updating OS](https://gist.github.com/Linerre/f11ad4a6a934dcf01ee8415c9457e7b2) `PATH` environment variable with `$GOPATH/bin`.
|
||
|
||
## Debugger
|
||
|
||
```bash
|
||
go install -v github.com/go-delve/delve/cmd/dlv@latest
|
||
```
|
||
|
||
# VsCode IDE
|
||
|
||
- Install [Visual Studio Code](https://code.visualstudio.com)
|
||
- `golang` extension
|
||
To launch *VS Code Quick Open* press (Ctrl + P), type: `ext install Go` , hit enter. Follow basic instructions.
|
||
|
||
# The Project
|
||
|
||
Inside `Visual Studio Code` Open Folder `Ctrl + Shift + E` , e.g.: `$USER\code\hello\`. Then Open `hello.go` from that folder. Or make new file (Ctrl + N) and save it on this folder:
|
||
|
||
```go
|
||
package main
|
||
|
||
import "fmt"
|
||
|
||
func main() {
|
||
fmt.Println("Hello World!")
|
||
i := 101
|
||
fmt.Println(i)
|
||
}
|
||
```
|
||
|
||
Some useful hotkeys:
|
||
- `Ctrl + Shift + D` - Open Debugger
|
||
- `F9` - set or toggle Breakpoint. *Try this line `i := 101`*
|
||
- `F5` - Start Debugging or to Run the Application. If asked to select environment: select `Go`
|
||
- `F10` - Step Over
|
||
- `F11` - Step Into
|
||
- `Shift + F11` - Step Out
|
||
- `Shift + F5` - Stop Debugging
|
||
- `Ctrl + Shift + F5` - Restart Debugging
|
||
|
||
Typical aka untouched `launch.json` :
|
||
|
||
```json
|
||
{
|
||
"version": "0.2.0",
|
||
"configurations": [
|
||
{
|
||
"name": "Launch",
|
||
"type": "go",
|
||
"request": "launch",
|
||
"mode": "debug",
|
||
"remotePath": "",
|
||
"port": 2345,
|
||
"host": "127.0.0.1",
|
||
"program": "${workspaceRoot}",
|
||
"env": {},
|
||
"args": [],
|
||
"showLog": true
|
||
}
|
||
]
|
||
}
|
||
``` |
