## Features
|
||
|
|
|
||
|
|
ANSI escape codes depend on terminal environment.
|
||
|
|
Some of these features may not work.
|
||
|
|
Check supported Font-Style/Font-Color features with [checkansi](./checkansi).
|
||

|
### Builder
|
||
|
|
|
||
|
|
To mix these features.
|
||
|
|
|
||
|
|
```go
|
||
|
|
custom := aec.EmptyBuilder.Right(2).RGB8BitF(128, 255, 64).RedB().ANSI
|
||
|
|
custom.Apply("Hello World")
|
||
|
|
```
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
1. Create ANSI by `aec.XXX().With(aec.YYY())` or `aec.EmptyBuilder.XXX().YYY().ANSI`
|
||
|
|
2. Print ANSI by `fmt.Print(ansi, "some string", aec.Reset)` or `fmt.Print(ansi.Apply("some string"))`
|
||
|
|
|
||
|
|
`aec.Reset` should be added when using font style or font color features.
|
||
|
|
|
||
|
|
## Example
|
||
|
|
|
||
|
|
Simple progressbar.
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
```go
|
||
|
|
package main
|
||
|
|
|
||
|
|
import (
|
||
|
|
"fmt"
|
||
|
|
"strings"
|
||
|
|
"time"
|
||
|
|
|
||
|
|
"github.com/morikuni/aec"
|
||
|
|
)
|
||
|
|
|
||
|
|
func main() {
|
||
|
|
const n = 20
|
||
|
|
builder := aec.EmptyBuilder
|
||
|
|
|
||
|
|
up2 := aec.Up(2)
|
||
|
|
col := aec.Column(n + 2)
|
||
|
|
bar := aec.Color8BitF(aec.NewRGB8Bit(64, 255, 64))
|
||
|
|
label := builder.LightRedF().Underline().With(col).Right(1).ANSI
|
||
|
|
|
||
|
|
// for up2
|
||
|
|
fmt.Println()
|
||
|
|
fmt.Println()
|
||
|
|
|
||
|
|
for i := 0; i <= n; i++ {
|
||
|
|
fmt.Print(up2)
|
||
|
|
fmt.Println(label.Apply(fmt.Sprint(i, "/", n)))
|
||
|
|
fmt.Print("[")
|
||
|
|
fmt.Print(bar.Apply(strings.Repeat("=", i)))
|
||
|
|
fmt.Println(col.Apply("]"))
|
||
|
|
time.Sleep(100 * time.Millisecond)
|
||
|
|
}
|
||
|
|
}
