Vala 0.5.3 (Default branch)
Vala is a new programming language that aims to bring modern programming language features to GNOME developers without imposing any additional runtime requirements, and without using a different ABI compared to applications and libraries written in C. License: GNU Lesser General Public License (LGPL) Changes:
D-Bus server support has been rewritten to directly use libdbus. Avoiding dbus-glib marshalling helps Vala to support complex D-Bus types more easily. All Vala structs will now be registered with GBoxed. Many critical warnings and crashes on invalid code have been fixed and replaced by better understandable error messages. Private class fields and class destructors are now supported. The vala-gen-project has been dropped from the package, and is now part of Vala Toys for gEdit. Many bugs have been fixed. Image

NAME

       sqlheavy-gen-orm - SQLHeavy ORM Generator

SYNOPSIS

       sqlheavy-gen-orm [OPTION...] SOURCE...

DESCRIPTION

       This  tool  will  generate a Vala file which provides an object for each table in the specified database(s), each of which extends the SQL-
       HeavyRecord class.

       You should pass at least one SQLite database file, which it will examine to produce the output. Additionally,  you  can	specifiy  metadata
       files (which is a key file), as well as vala files to provide custom code in the output.

OPTIONS

       --help

       -o, --output=FILE
	      Write output to FILE (defaults to stdout)

       -m, --metadata=FILE
	      Load metadata from FILE

       --vapidir=DIRECTORY
	      Look for package bindings in DIRECTORY

       --pkg=PACKAGE
	      Include binding for PACKAGE

       -o, --output=FILE
	      Output to FILE (default is stdout)

       -p, --properties
	      Write properties instead of methods

METADATA FORMAT

       The concept of the metadata files is similar to that of vapigen (in fact, the entire sqlheavy-gen-orm tool is largely inspired by vapigen),
       but it uses the key file format so that it can use the GLib Key-Value file parser. Databases, tables, and columns are  all  represented	by
       groups, each of which may have any number of properties (the key value pairs).

   Selectors
       The  format  for the selectors is relatively straightforward. A forward slash ("/") is used as the separator character, and prepending an @
       to a token means that token refers to a database, and prepending a % means that token refers to a table. The database name is the  name	of
       the database file, not including the last dot character and anything following it (i.e., the extension). An asterisk can be used as a wild-
       card. Several examples, as well as an explanation of each:

       @foo/bar/baz
	      The baz symbol in the bar table in the foo database.

       @foo   The foo database

       %bar/baz
	      The baz column in the bar table in any database

       baz    The baz column in any table in any database

       @foo/*/baz
	      The baz column in any table in the foo database

       */bar  The bar table in any database

   Properties
       Properties are represented by key-value pairs. The following is a table of currently implemented properties:

       +-------+--------+------------+---------------------------------+
       | Name  |  Type	| DB/TBL/COL |		   Purpose	       |
       +-------+--------+------------+---------------------------------+
       |name   | string | Y/Y/Y      | Rename the symbol	       |
       |type   | string | N/N/Y      | Set the Vala type of the column |
       |hidden | bool	| Y/Y/Y      | Do not create a binding	       |
       +-------+--------+------------+---------------------------------+
   Custom Vala
       In addition to providing one or more SQLite database as a basis for code generation, you can provide an	existing  *.vala  file.  Theoreti-
       cally, this will allow you to place custom code in a separate file, so that you can use sqlheavy-gen-orm to update the generated code with-
       out losing whenever the database schema changes, and you will not lose any enhancements you made. The generated code will  be  merged  into
       the custom vala file in order to generate the output.
