NAME

Data::Org::Template - template engine that plays well with iterators

VERSION

Version 0.04

SYNOPSIS

CREATING A TEMPLATE

new (text, [start, end])

Aside from the text to be loaded as a template, you can also provide delimiters for the fields in start and end. If only one string is provided, it is assumed to encode both start *and* end, and will be split in equal halves. The default delimiters are [[ and ]].

EXPRESSING A TEMPLATE

A template can be either fully or partly expressed. If it's only partly expressed, the result is a new template with some of the fields replaced with values, and others left intact.

If the template uses transducers we don't recognize, it will croak with an appropriate warning.

iter([data getter])

Starts a token iterator from the template. A token stream, the way I do it, is an iterator for which each value returned is either a string (plain text) or a token. A token is an arrayref of [type, value, <arbitrary stuff>], so extracting the value is easy.

If no data getter is specified, uses the one registered in the template. If none is registered, croaks because you can't express a template on nothing, can you?

_compile_token_stream ($stream)

This is just a helper function - NOT object-oriented in nature (the initial underscore might help you - and me - remember that).

text()

Compiles the iterator into an output string for you, using _compile_token_stream.

REGISTERING A DATA GETTER

A template can be expressed by providing a data getter (a map from name to value) at expression time, but you can also register a default data getter against the template when you define it, for convenience.

data_getter ([data getter])

Sets or gets the current data getter for the template. If you pass one or more data getters (which can be a data getter object, a hashref, or an arrayref of other data getters) then each will be checked in sequence.
