Blatte 0.9.4

Blatte is a Perl module with text macro/markup/template language.

SYNOPSIS

use Blatte;
use Blatte::Builtins;

my $perl = &Blatte::Parse(...some Blatte program ...);
if (defined($perl)) {
my $result = eval $perl;
if (defined($result)) {
&Blatte::traverse($result, &callback);
} elsif ($@) {
...handle execution error...
}
} else {
...handle parsing error...
}

Blatte is a very powerful text markup and transformation language with a very simple syntax. A Blatte document can be translated into a Perl program that, when executed, produces a transformed version of the input document.

This module itself contains some utility functions for handling Blatte documents, described below in the FUNCTIONS section. However, writers of Blatte-based software will generally be more interested in other associated modules. See in particular Blatte::Compiler (for processing files full of Blatte code) and Blatte::Builtins (for a description of the Blatte languages intrinsic functions).

Most casual end users will probably be interested in Blattes ability to serve as a higher-level language for writing web pages. This requires the additional CPAN package Blatte::HTML.

Most of the remainder of this document describes the syntax and semantics of the Blatte language.
