Text::CleanFragment - clean up text to use as URL fragment or filename
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.
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.
