# Motd generator using FIGlet
|
|
|
|
[](https://goreportcard.com/report/github.com/kevinmidboe/motdGO)
|
|
|
|
`motdGO` is a library based on [figlet4go](https://github.com/mbndr/figlet4go) which is a go library which is a port of [FIGlet](http://www.figlet.org/) to Golang.
|
|
With `motdGO` it's easy to create **ascii text banners for motd** in the command-line or with the given api.
|
|
|
|
|
|
|
|
## Build locally
|
|
|
|
Initialize project:
|
|
```bash
|
|
make init
|
|
```
|
|
|
|
Install dependencies:
|
|
```bash
|
|
make install
|
|
```
|
|
|
|
## Usage
|
|
|
|
### Binary from web
|
|
Download and run binary:
|
|
|
|
```bash
|
|
wget 'https://raw.githubusercontent.com/kevinmidboe/motdGO/main/motd'
|
|
chmod +x motd
|
|
./motd -str 'hello world'
|
|
```
|
|
|
|
### Command-line from source
|
|
Run using `go run` from source code:
|
|
|
|
```bash
|
|
go run cmd/motdGO/main.go -str 'hello world'
|
|
```
|
|
|
|
### Command-line
|
|
You can use the `motdGO` command in the command-line.
|
|
For example (generates the banner on top):
|
|
```bash
|
|
$ motdGO -str "hello world" -font "larry3d" -colors "green;FF9900;cyan"
|
|
```
|
|
For a usage instruction read the commands usage with `motdGO -h`.
|
|
|
|
### Basic
|
|
You have to create a renderer (`ascii`) and let it render the desired string through the `Render` method. After that you can simply print the returned string.
|
|
```go
|
|
import "github.com/kevinmidboe/motdGO"
|
|
|
|
// ...
|
|
|
|
ascii := motdGO.NewAsciiRender()
|
|
|
|
// The underscore would be an error
|
|
renderStr, _ := ascii.Render("Hello World")
|
|
fmt.Print(renderStr)
|
|
```
|
|
|
|
### Colored
|
|
The colors given in the `[]motdGO.Color` slice are repeating if the string is longer than the slice. You have to call the `RenderOpts` instead of the `Render` method to give the Renderer the Options.
|
|
If you use a `TrueColor` color, you have to ensure that your [terminal supports](https://gist.github.com/XVilka/8346728/) it.
|
|
If you use a `AnsiColor` with an `TrueColor` only parser (f.e. `ParserHTML`), `TrueColor` objects are automatically generated.
|
|
```go
|
|
import "github.com/kevinmidboe/motdGO"
|
|
|
|
// ...
|
|
|
|
ascii := motdGO.NewAsciiRender()
|
|
|
|
// Adding the colors to RenderOptions
|
|
options := motdGO.NewRenderOptions()
|
|
options.FontColor = []motdGO.Color{
|
|
// Colors can be given by default ansi color codes...
|
|
motdGO.ColorGreen,
|
|
motdGO.ColorYellow,
|
|
motdGO.ColorCyan,
|
|
// ...or by an hex string...
|
|
motdGO.NewTrueColorFromHexString("885DBA"),
|
|
// ...or by an TrueColor object with rgb values
|
|
motdGO.TrueColor{136, 93, 186},
|
|
}
|
|
|
|
renderStr, _ := ascii.RenderOpts("Hello Colors", options)
|
|
fmt.Print(renderStr)
|
|
```
|
|
|
|
### Other font
|
|
If you want to use another font, you have to specify the name of the font as in this example.
|
|
Is the font you want to use not [included](#builtin) you have to load the font manually with the `LoadFont` method. This method will walk the path recursively and load all `.flf` files.
|
|
```go
|
|
import "github.com/kevinmidboe/motdGO"
|
|
|
|
// ...
|
|
|
|
ascii := motdGO.NewAsciiRender()
|
|
|
|
options := motdGO.NewRenderOptions()
|
|
options.FontName = "larry3d"
|
|
|
|
// If 'larry3d' wouldn't be included you would have to load your .flf files like that:
|
|
ascii.LoadFont("/path/to/fonts/")
|
|
|
|
renderStr, _ := ascii.RenderOpts("Hello Fonts", options)
|
|
fmt.Print(renderStr)
|
|
```
|
|
|
|
### Other parser
|
|
A Parser can be set through the `GetParser` function with a valid key
|
|
```go
|
|
import "github.com/kevinmidboe/motdGO"
|
|
|
|
// ...
|
|
|
|
ascii := motdGO.NewAsciiRender()
|
|
|
|
options := motdGO.NewRenderOptions()
|
|
p, _ := motdGO.GetParser("html")
|
|
options.Parser = *p
|
|
|
|
renderStr, _ := ascii.RenderOpts("Hello Fonts", options)
|
|
fmt.Print(renderStr)
|
|
```
|
|
|
|
## Parsers
|
|
There a currently these Parsers available:
|
|
|
|
| Parser | What does it do? |
|
|
| --------- | ------ |
|
|
| ParserTerminal | Parses the result directly |
|
|
| ParserHTML | Parses a pasteable `<code>` html block |
|
|
|
|
## Fonts
|
|
|
|
### Builtin
|
|
The builtin fonts are built into the `bindata.go` file with the tool [go-bindata](https://github.com/jteeuwen/go-bindata).
|
|
The bash script for building the default font is stored in `tools/` (`go-bindata` must be installed).
|
|
|
|
The default font is `standard`. These are the builtin fonts:
|
|
|
|
| Font name | Source |
|
|
| --------- | ------ |
|
|
| standard | http://www.figlet.org/fontdb_example.cgi?font=standard.flf |
|
|
| larry3d | http://www.figlet.org/fontdb_example.cgi?font=larry3d.flf |
|
|
|
|
### Other fonts
|
|
Other fonts can mainly be found on [figlet](http://www.figlet.org). You have to load them as in [this example](#other-font).
