mutter
$ my words come out,
in color and
style
mutter takes the concepts of separation of style & content to the command-line!
synopsis
require 'mutter'
mut = Mutter.new # creates a new 'Mutterer', who talks in command-line language
mut.say "hello _world_" # underlines 'world'
mut.say "hello world", :bold # bolds the whole string
mut.say "hello [world]", :cyan # inverts 'world', and colors the string cyan
mut.print "bonjour!" # alias of `say`
mut["_hola_"] # return the stylized string without printing
styles
mutter supports these styles:
:bold, :underline, :inverse, :blink
and these colors:
:red, :green, :blue, :yellow, :cyan, :purple, :white, :black
customization
styles = {
:warning => { # an alias you can use anywhere in mutter
:match => ['*!', '!*'], # will match *!mutter!*
:style => ['yellow', 'bold'] # these styles will be applied to the match
},
:error => {
:match => '!!', # will match !!mutter!!
:style => ['red', 'underline']
}
}
mut = Mutter.new(styles)
mut.say "warning, the dogs have escaped!", :warning # These two are
mut.warning "warning, the dogs have escaped!" # equivalent
mut.say "gosh, we have an !!error!!"
YAML
The previous example could have (and should really have) been written in a separate .yml file, like so:
warning:
match:
- '*!'
- '!*
style:
- yellow
- bold
error:
match: '!!'
style:
- red
- underline
and then loaded like this:
Mutter.new("styles.yml")
quick styles
mut = Mutter.new :yellow => '~'
mut.say "~[black on yellow!]~"
add/remove styles from an instance
mut = Mutter.new(:blink)
mut >> :blink # remove :blink
mut << :bold << :underline # add :bold and :underline
mut.say "hello mutter." # bold and underlined
installation
$ sudo gem install cloudhead-mutter
That's it!
have fun
Footnote
This code is highly experimental, don't try this at home!
