Flott - Floris Tolle Templates
This is ruby templating system with some unique features.
Installation
Use rubygems and just type:
gem install permutation
Usage
If you want to play with the parser it's best to use the Flott method:
Flott('1 + 1 = [=1 + 1]') # => "1 + 1 = 2"
However if you want to take advantage of the directory tree walking and inclusion features, you have to use actual files:
If two template files are stored in the current directory. One file "header":
Hello [=@name]!
[for i in 1..6 if i % 2 == 0-] Hello [=@name]! [else-] Hello [=@name]! [end end-]The parser can be used like this fp = Flott::Parser.from_filename('template') env = Flott::Environment.new env = "Florian" fp.evaluate(env)
Or this: puts Flott.string_from_file(filename, :name => "Florian")
You should also take a look at the other convenience methods in the Flott module.
The output is created by including "header" into "template" with the [^filename] syntax. [!@name] is a shortcut for [print @name] while [=@name] first calls Flott::Parser.escape on @name. It's also possible to just print or puts strings.
Note the use of the assignment to the instance variable @name before executing the template. The state passed to Parser#evaluate as an environment and can be referenced in the template itself with [=@name].
After execution the output is:
Hello Florian!
Hello Florian! Hello Florian! Hello Florian! Hello Florian! Hello Florian! Hello Florian!Author
