NAME
Text::CleanFragment - clean up text to use as URL fragment or filename
SYNOPSIS
my $title = "Do p\x{00FC}t <this> into URL's?";
my $id = 42;
my $url = join "/",
$id,
clean_fragment( $title );
# 42/Do_put_this_into_URLs
This module downgrades strings of text to match
/^[-._A-Za-z0-9]*$/
or, to be more exact
/^([-.A-Za-z0-9]([-._A-Za-z0-9]*[-.A-Za-z0-9])?$/
This makes the return values safe to be used as URL fragments or as file
names on many file systems where whitespace and characters outside of
the Latin alphabet are undesired or problematic.
FUNCTIONS
`clean_fragment( @fragments )'
my $url_title = join("_", clean_fragment("Ümloud vs. ß",'by',"Grégory"));
# Umloud_vs._ss_by_Gregory
Returns a cleaned up list of elements. The input elements are expected
to be encoded as Unicode strings. Decode them using Encode if you read
the fragments as file names from the filesystem.
The operations performed are:
* Use Text::Unidecode to downgrade the text from Unicode to 7-bit
ASCII.
* Eliminate single and double quotes, apostrophes.
* Replace all non-letters, non-digits by underscores, including
whitespace and control characters.
* Squash dashes to a single dash
* Squash `_-_' and `_-_(-_)+' to -
* Eliminate leading underscores
* Eliminate trailing underscores
* Eliminate underscores before - or .
In scalar context, returns the first element of the cleaned up list.
