SQL::Translator::Filter::Names(3pm)			User Contributed Perl Documentation		       SQL::Translator::Filter::Names(3pm)

NAME
SQL::Translator::Filter::Names - Tweak the names of schema objects. SYNOPSIS
#! /usr/bin/perl -w use SQL::Translator; # Lowercase all table names and upper case the first letter of all field # names. (MySql style!) # my $sqlt = SQL::Translator->new( filename => @ARGV, from => 'MySQL', to => 'MySQL', filters => [ Names => { 'tables' => 'lc', 'fields' => 'ucfirst', }, ], ) || die "SQLFairy error : ".SQL::Translator->error; print($sqlt->translate) || die "SQLFairy error : ".$sqlt->error; DESCRIPTION
SEE ALSO
perl(1), SQL::Translator BUGS
TODO
Name Groups Define a bunch of useful groups to run the name filters over. e.g. all, fkeys, pkeys etc. More Functions e.g. camelcase, titlecase, single word etc. Also a way to pass in a regexp. May also want a way to pass in arguments for the func e.g. prefix. Multiple Filters on the same name (filter order)? Do we actually need this, you could just run lots of filters. Would make adding func args to the interface easier. filters => [ [ 'Names', { all => 'lc' } ], [ 'Names', { tables => 'lc', fields => 'ucfirst', } ], ], Mind you if you could give the filter a list this wouldn't be a problem! filters => [ [ 'Names', all => 'lc' fields => 'ucfirst', ], ], Which is nice. Might have to change the calling conventions for filters. Would also provide an order to run the filters in rather than having to hard code it into the filter it's self. AUTHOR
