template::plugin::datafile
Template::Plugin::Datafile(3pm) User Contributed Perl Documentation Template::Plugin::Datafile(3pm)
NAME
Template::Plugin::Datafile - Plugin to construct records from a simple data file
SYNOPSIS
[% USE mydata = datafile('/path/to/datafile') %]
[% USE mydata = datafile('/path/to/datafile', delim = '|') %]
[% FOREACH record = mydata %]
[% record.this %] [% record.that %]
[% END %]
DESCRIPTION
This plugin provides a simple facility to construct a list of hash references, each of which represents a data record of known structure,
from a data file.
[% USE datafile(filename) %]
A absolute filename must be specified (for this initial implementation at least - in a future version it might also use the
"INCLUDE_PATH"). An optional "delim" parameter may also be provided to specify an alternate delimiter character.
[% USE userlist = datafile('/path/to/file/users') %]
[% USE things = datafile('items', delim = '|') %]
The format of the file is intentionally simple. The first line defines the field names, delimited by colons with optional surrounding
whitespace. Subsequent lines then defines records containing data items, also delimited by colons. e.g.
id : name : email : tel
abw : Andy Wardley : abw@tt2.org : 555-1234
sam : Simon Matthews : sam@tt2.org : 555-9876
Each line is read, split into composite fields, and then used to initialise a hash array containing the field names as relevant keys. The
plugin returns a blessed list reference containing the hash references in the order as defined in the file.
[% FOREACH user = userlist %]
[% user.id %]: [% user.name %]
[% END %]
The first line of the file must contain the field definitions. After the first line, blank lines will be ignored, along with comment line
which start with a '"#"'.
BUGS
Should handle file names relative to "INCLUDE_PATH". Doesn't permit use of '":"' in a field. Some escaping mechanism is required.
