# Go Figure
## Description
Go Figure prints beautiful ASCII art from text.
It supports [FIGlet](http://www.figlet.org/) files,
and most of its features.
This package was inspired by the Ruby gem [artii](https://github.com/miketierney/artii),
but built from scratch and with a different feature set.
## Installation
`go get github.com/common-nighthawk/go-figure`
## Basic Example
```go
package main
import("github.com/common-nighthawk/go-figure")
func main() {
myFigure := figure.NewFigure("Hello World", "", true)
myFigure.Print()
}
```
```txt
_ _ _ _ __ __ _ _
| | | | ___ | | | | ___ \ \ / / ___ _ __ | | __| |
| |_| | / _ \ | | | | / _ \ \ \ /\ / / / _ \ | '__| | | / _` |
| _ | | __/ | | | | | (_) | \ V V / | (_) | | | | | | (_| |
|_| |_| \___| |_| |_| \___/ \_/\_/ \___/ |_| |_| \__,_|
```
You can also make colorful figures:
```go
func main() {
myFigure := figure.NewColorFigure("Hello World", "", "green", true)
myFigure.Print()
}
```
## Documentation
### Create a Figure
There are three ways to create a Figure. These are--
the method `func NewFigure`,
the method `func NewColorFigure`, and
the method `func NewFigureWithFont`.
Each constructor takes the arguments: the text, font, and strict mode.
The "color" constructor takes a color as an additional arg.
The "with font" specifies the font differently.
The method signature are:
```
func NewFigure(phrase, fontName string, strict bool) figure
func NewColorFigure(phrase, fontName string, color string, strict bool) figure
func NewFigureWithFont(phrase string, reader io.Reader, strict bool) figure
```
`NewFigure` requires only the name of the font, and uses the font file shipped
with this package stored in bindata.
If passed an empty string for the font name, a default is provided.
That is, these are both valid--
`myFigure := figure.NewFigure("Foo Bar", "", true)`
`myFigure := figure.NewFigure("Foo Bar", "alphabet", true)`
Please note that font names are case sensitive.
`NewFigureWithFont`, on the other hand, accepts the font file directly.
This allows you to BYOF (bring your own font).
Provide the absolute path to the flf.
You can point to a file the comes with this project
or you can store the file anywhere you'd like and use that location.
The font files are available in the [fonts folder](https://github.com/common-nighthawk/go-figure/tree/master/fonts)
and on [figlet.org](http://www.figlet.org/fontdb.cgi).
Here are two examples--
`myFigure := figure.NewFigureWithFont("Foo Bar", "/home/ubuntu/go/src/github.com/common-nighthawk/go-figure/fonts/alphabet.flf", true)`
`myFigure := figure.NewFigureWithFont("Foo Bar", "/home/lib/fonts/alaphabet.flf", true)`
You can also make colorful figures! The current supported colors are:
blue, cyan, gray, green, purple, red, white, yellow.
An example--
`myFigure := figure.NewColorFigure("Foo Bar", "", "green", true)
Strict mode dictates how to handle characters outside of standard ASCII.
When set to true, a non-ASCII character (outside character codes 32-127)
will cause the program to panic.
When set to false, these characters are replaced with a question mark ('?').
Examples of each--
`figure.NewFigure("Foo 👍 Bar", "alphabet", true).Print()`
```txt
2016/12/01 19:35:38 invalid input.
```
`figure.NewFigure("Foo 👍 Bar", "alphabet", false).Print()`
```txt
_____ ___ ____
| ___| ___ ___ |__ \ | __ ) __ _ _ __
| |_ / _ \ / _ \ / / | _ \ / _` | | '__|
| _| | (_) | | (_) | |_| | |_) | | (_| | | |
|_| \___/ \___/ (_) |____/ \__,_| |_|
```
### Methods: stdout
#### Print()
The most basic, and common, method is func Print.
A figure responds to Print(), and will write the output to the terminal.
There is no return value.
`myFigure.Print()`
But if you're feeling adventurous,
explore the methods below.
#### Blink(duration, timeOn, timeOff int)
A figure responds to the func Blink, taking three arguments.
`duration` is the total time the banner will display, in milliseconds.
`timeOn` is the length of time the text will blink on (also in ms).
`timeOff` is the length of time the text will blink off (ms).
For an even blink, set `timeOff` to -1
(same as setting `timeOff` to the value of `timeOn`).
There is no return value.
`myFigure.Blink(5000, 1000, 500)`
`myFigure.Blink(5000, 1000, -1)`
#### Scroll(duration, stillness int, direction string)
A figure responds to the func Scroll, taking three arguments.
`duration` is the total time the banner will display, in milliseconds.
`stillness` is the length of time the text will not move (also in ms).
Therefore, the lower the stillness the faster the scroll speed.
`direction` can be either "right" or "left" (case insensitive).
The direction will be left if an invalid option (e.g. "foo") is passed.
There is no return value.
`myFigure.Scroll(5000, 200, "right")`
`myFigure.Scroll(5000, 100, "left")`
#### Dance(duration, freeze int)
A figure responds to the func Dance, taking two arguments.
`duration` is the total time the banner will display, in milliseconds.
`freeze` is the length of time between dance moves (also in ms).
Therefore, the lower the freeze the faster the dancing.
There is no return value.
`myFigure.Dance(5000, 800)`
### Methods: Writers
#### Write(w io.Writer, fig figure)
Unlike the above methods that operate on a figure value,
func Write is a function that takes two arguments.
`w` is a value that implements all the methods in the io.Writer interface.
`fig` is the figure that will be written.
`figure.Write(w, myFigure)`
This method would be useful, for example, to add a nifty banner to a web page--
```go
func landingPage(w http.ResponseWriter, r *http.Request) {
figure.Write(w, myFigure)
}
```
### Methods: Misc
#### Slicify() ([]string)
If you want to do something outside of the created methods,
you can grab the internal slice.
This gives you a good start to build anything
with the ASCII art, if manually.
A figure responds to the func Slicify,
and will return the slice of strings.
`myFigure.Slicify()`
returns
```txt
["FFFF BBBB ",
"F B B ",
"FFF ooo ooo BBBB aa rrr",
"F o o o o B B a a r ",
"F ooo ooo BBBB aaa r "]
```
## More Examples
`figure.NewFigure("Go-Figure", "isometric1", true).Print()`
```
