NAME ^

Bigtop::Backend::SQL::SQLite - backend to generate sql for SQLite database creation

SYNOPSIS ^

If your bigtop file looks like this:

    config {
        SQL  SQLite {}
    }
    app App::Name {
    }

and there are table and/or sequence blocks in the app block, this module will make docs/schema.sqlite (relative to the build_dir) when you type:

    bigtop app.bigtop SQL

or

    bigtop app.bigtop all

You can feed that file directly to psql, once you have created a database. That is type:

    sqlite dbname < docs/schema.sqlite

DESCRIPTION ^

This is a Bigtop backend which generates SQL SQLite can understand.

KEYWORDS ^

This module defines no keywords. Look in Bigtop::SQL for a list of the keywords you can use in table and sequence blocks.

Note that SQLite does not support sequences. Trying to use them with this backend will be fatal.

SHORTHAND for is arguments ^

This module does provide a couple of bits of shorthand (some aren't so short) for the arguments of the is field statement.

    field id {
        is int4, primary_key, auto;
    }

This translates into:

    id INTEGER PRIMARY KEY AUTOINCREMENT

You can also type 'assign_by_sequence' instead of 'auto'. That might aid understanding, if you can type it correctly.

Note that using 'primary_key' instead of the literal 'PRIMARY KEY' is important. It tells the SQL and the Model back ends that this is the primary key.

METHODS ^

To keep podcoverage tests happy.

backend_block_keywords

Tells tentmaker that I understand these config section backend block keywords:

    no_gen
    template
what_do_you_make

Tells tentmaker what this module makes. Summary: docs/schema.sqlite.

gen_SQL

Called by Bigtop::Parser to get me to do my thing.

setup_template

Called by Bigtop::Parser so the user can substitute an alternate template for the hard coded one here.
