No need for a link, just enter "man test" on your commandline and be enlightened. ;-))

what is the => representing here?
Nothing. I just explained above, that in my example i assume x to be 5 and y to be 10. And if you ask "is x greater than y" this would return a logical FALSE. You could test this by entering the following on your commandline:

Code:
x=5
y=10
test $x -gt $y ; echo $?
test $y -gt $x ; echo $?

Line 3 would print "1", which is a logical "FALSE" and line 4 would print a "0", which is a logical TRUE.

NAME
SQL::Translator::Parser::DBIx::Class - Create a SQL::Translator schema from a DBIx::Class::Schema instance SYNOPSIS
## Via DBIx::Class use MyApp::Schema; my $schema = MyApp::Schema->connect("dbi:SQLite:something.db"); $schema->create_ddl_dir(); ## or $schema->deploy(); ## Standalone use MyApp::Schema; use SQL::Translator; my $schema = MyApp::Schema->connect; my $trans = SQL::Translator->new ( parser => 'SQL::Translator::Parser::DBIx::Class', parser_args => { package => $schema, add_fk_index => 0, sources => [qw/ Artist CD /], }, producer => 'SQLite', ) or die SQL::Translator->error; my $out = $trans->translate() or die $trans->error; DESCRIPTION
This class requires SQL::Translator installed to work. "SQL::Translator::Parser::DBIx::Class" reads a DBIx::Class schema, interrogates the columns, and stuffs it all in an $sqlt_schema object. Its primary use is in deploying database layouts described as a set of DBIx::Class classes, to a database. To do this, see "deploy" in DBIx::Class::Schema. This can also be achieved by having DBIx::Class export the schema as a set of SQL files ready for import into your database, or passed to other machines that need to have your application installed but don't have SQL::Translator installed. To do this see "create_ddl_dir" in DBIx::Class::Schema. PARSER OPTIONS
add_fk_index Create an index for each foreign key. Enabled by default, as having indexed foreign key columns is normally the sensible thing to do. sources Arguments: @class_names Limit the amount of parsed sources by supplying an explicit list of source names. SEE ALSO
