# virtual-term
virtualTerm is created to simulate a terminal,handle the special character such as '\r','\b'.
Write a string into VirtualTerm, you will know what would your string be like if you output it to stdout.
## Now Support 😎
### Character Encoding
* ASCII
* UTF-8
### Control Characters
* `\b` backspace
* `\r` carriage return
* `\n` feed line
* `ESC[#A` moves cursor up # lines
* `ESC[#B` moves cursor down # lines
* `ESC[#C` moves cursor right # columns
* `ESC[#D` moves cursor left # columns
* `ESC[H` moves cursor to home position
***WARNING:*** if you try to write not supported ESC to it, the output may can not be predicted
## install🛸
you need go mod to use it. Just always use the latest version.
```shell
go get -u github.com/chengxilo/virtualterm
```
## Getting Started 🤔
example
```go
package main
import (
"fmt"
"github.com/chengxilo/virtualterm"
"log"
)
func main() {
str := "hello\rvirtuaa\bl-terminal"
vt := virtualterm.NewDefault()
vt.Write([]byte(str))
fmt.Println(str == "virtual-terminal")
str,err := vt.String()
if err != nil {
log.Fatal(err)
}
fmt.Println(str == "virtual-terminal")
// Output:
// false
// true
}
```
Use `virtualterm.Process` function. You will not need to create a virtual terminal and input on your own.
```golang
package main
import (
"fmt"
"github.com/chengxilo/virtualterm"
)
func main() {
str := "hello\rvirtuaa\bl-terminal"
newS,_ := virtualterm.Process(str)
fmt.Println(str == "virtual-terminal")
fmt.Println(newS == "virtual-terminal")
// Output:
// false
// true
}
```
go test. This is why I want to create this repository.
If you don't use this,just use the str, all of them will fail.
```go
package test
import (
"fmt"
"github.com/chengxilo/virtualterm"
"github.com/stretchr/testify/assert"
"testing"
)
func TestVirtualTerm(t *testing.T) {
str := "hello\rvirtuaa\bl-terminal"
ns,_ := virtualterm.Process(str)
assert.Equal(t, ns, "virtual-terminal")
}
func ExampleVirtualTerm() {
str := "hello\rvirtuaa\bl-terminal"
ns,_ := virtualterm.Process(str)
fmt.Print(ns)
// Output:
// virtual-terminal
}
```
