SQL::Tr...::Parser(3)

✨ NAME ✨

okay so this is the User Contributed Perl Documentation page for SQL::Tr...::Parser(3), and it's literally the page that describes how to write a parser for SQL::Translator. bestie, if you're building one of these, this is your vibe check 💅.

💖 DESCRIPTION 💖

so the parser modules that SQL::Translator invokes? they need to implement a single function: parse. that's the whole requirement, no cap. SQL::Translator calls it like this:

$class::parse($tr, $data_as_string)

where $tr is a SQL::Translator instance. after that? the classes are free to define any helper functions they want, or use any design pattern internally that makes the most sense. do your thing ✨.

once the parser has figured out what exists, it communicates the structure to the producer through the SQL::Translator::Schema object. you can get that object from the translator — the first argument passed to parse — by calling the schema method:

my $schema = $tr->schema;

the Schema object has methods for adding tables, fields, indices, etc. iconic. for more info, consult the docs for SQL::Translator::Schema and its related modules. and for examples of how this actually works, go examine the source code for existing SQL::Translator::Parser::* modules. iykyk 🫶.
