# NAME

Data::FormValidator::Filters::WikiTrim - Trim filter for wikitext fields

# SYNOPSIS

```perl

use Data::FormValidator::Filters::WikiTrim qw(wiki_trim);

# Build Data::FormValidator profile

my $profile = {

    'required' => [qw( subject body )],

    'field_filters' => {

        'subject' => 'trim',

        'body'    => wiki_trim(),

    },

};

```

# DESCRIPTION

`Data::FormValidator::Filters::WikiTrim` provides a slightly different `trim`

filter than the default.  Rather than trimming _all_ leading/trailing

whitespace, we trim all leading _blank lines_ and all trailing whitespace.  In

a wikitext field, leading spaces on the first line could be important so they

need to be preserved (while leading blank lines aren't important and could be

trimmed out).

# METHODS

- wiki\_trim()

    Returns a filter which trims leading/trailing whitespace in a manner more

    suitable for wikitext entry fields; leading blank -lines- are trimmed, as

    well as all trailing whitespace.

    This differs from the standard "trim" filter in that we're only trimming

    leading blank -lines- but leave any leading whitespace on the first line;

    those leading spaces may be important.
