    OpusVL::Text::Util - Simple text utilities

VERSION

    version 0.10

SYNOPSIS

    This provides a couple of simple methods for playing with text.

        use OpusVL::Text::Util qw/truncate_text wrap_text/;
    
        my $truncated = truncate_text('a long string really', 10);
        # 'a long...'
        my $wrapped = truncate_text('a long string really', 10);
        $wrapped = "a long\nstring really";

EXPORT

 truncate_text

    This truncates a string close to the limit provided. It tries to break
    it on a word break if possible. It then appends a '...' to the string.
    This isn't included in the calculation of the length, so you may end up
    with 3 more characters than you specified.

        my $truncated = truncate_text('a long string really', 10);
        # 'a long...'

 wrap_text

    This method has a go at wrapping a line of text. Note that it isn't
    designed to work on multiple lines of text. It will attempt to split at
    convenient points within the required width and if that fails it will
    simply display what is there. All the text should be displayed with
    this method.

    You can also specify the linefeed characters as the last parameter.

        my $wrapped = wrap_text('a long string really', 10);
        # "a long\nstring\nreally"
        my $wrapped = wrap_text('a long string really', 10, "\r\n");
        # "a long\r\nstring\r\nreally"

 string_to_id

    Makes a string safe to use as an HTML id. Converts all non safe
    characters to _.

        string_to_id('thuds-!this') # 'thuds__this'

 line_split

    Splits a string on line breaks. Accounts for all 3 types of line break,
    DOS, MAC and Unix.

        line_split("a\nb\r\nc") # qw/a b c/

 missing_array_items

    Returns the list of items missing.

        $mandatory = [qw/a b c/];
        $cols = [qw/a b d e f/];
        missing_array_items($mandatory, $cols); # ['c']

 not_blank

    Returns true if the string provided is not blank.

        not_blank('0') # 0
        not_blank('')  # 1

 split_words

    Splits a list of words in a string. Looks for commas to split the list
    and strips whitespace.

        split_words('veh1,veh2,veh3') #  qw/veh1 veh2 veh3/

 mask_text

    Mask text field contents using a simple regex.

        mask_text('*', '(\d{4}).*(\d{3})', '456456564654654');
        # '4564********654'

    Specify a fill character, a regex (as a string), and the text to mask
    out.

    This does not guard against rogue regexes. Capture the parts you expect
    to be retained.

 split_camel_case

    Split a camel case word into an arrayref. This assumes you're giving it
    a word, behaviour when passed something like a sentence is undefined.

        split_camel_case('TemplateNotMatchedException')
        # ['Template', 'Not', 'Matched', 'Exception']
