// TODO Windows. Identify bug in GOLang 1.5.1+ and/or Windows Server 2016 TP5.
// @jhowardmsft, @swernli.
//
// On Windows, this mitigates a problem with the default options of running
// a docker client against a local docker daemon on TP5.
//
// What was found that if the default host is "localhost", even if the client
// (and daemon as this is local) is not physically on a network, and the DNS
// cache is flushed (ipconfig /flushdns), then the client will pause for
// exactly one second when connecting to the daemon for calls. For example
// using docker run windowsservercore cmd, the CLI will send a create followed
// by an attach. You see the delay between the attach finishing and the attach
// being seen by the daemon.
//
// Here's some daemon debug logs with additional debug spew put in. The
// AfterWriteJSON log is the very last thing the daemon does as part of the

// We suspect this is either a bug introduced in GOLang 1.5.1, or that a change
// in GOLang 1.5.1 (from 1.4.3) is exposing a bug in Windows. In theory,
// the Windows networking stack is supposed to resolve "localhost" internally,
// without hitting DNS, or even reading the hosts file (which is why localhost
// is commented out in the hosts file on Windows).
//
// We have validated that working around this using the actual IPv4 localhost
// address does not cause the delay.
//
// This does not occur with the docker client built with 1.4.3 on the same
// Windows build, regardless of whether the daemon is built using 1.5.1
// or 1.4.3. It does not occur on Linux. We also verified we see the same thing
// on a cross-compiled Windows binary (from Linux).
//
// Final note: This is a mitigation, not a 'real' fix. It is still susceptible
// to the delay if a user were to do 'docker run -H=tcp://localhost:2375...'
// explicitly.
// DefaultHTTPHost Default HTTP Host used if only port is provided to -H flag e.g. dockerd -H tcp://:8080

# aec
[![GoDoc](https://godoc.org/github.com/morikuni/aec?status.svg)](https://godoc.org/github.com/morikuni/aec)
Go wrapper for ANSI escape code.
## Install
```bash
go get github.com/morikuni/aec
```
## 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).
[Wikipedia](https://en.wikipedia.org/wiki/ANSI_escape_code) for more detail.
### Cursor
- `Up(n)`
- `Down(n)`
- `Right(n)`

### Color Converter
24bit RGB color to ANSI color.
- `NewRGB3Bit(r, g, b)`
- `NewRGB8Bit(r, g, b)`
### 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.
![sample](./sample.gif)
```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)
}
}
```
