rarchdb

A small read only database Mainly to be used by retroarch

Usage

To convert a dat file use dat_converter <dat file> <db file>

To list out the content of a db rarchdb_tool <db file> list To create an index rarchdb_tool <db file> create-index <index name> <field name> To find an entry with an index rarchdb_tool <db file> find <index name> <value>

The util mkdb.sh <dat file> <db file> will create a db file with indexes for crc sha1 and md5

lua converters

In order to write you own converter you must have a lua file that implements the following functions:

-- this function gets called before the db is created and shuold validate the
-- arguments and set up the ground for db insertion
function init(...)
	local args = {...}
	local script_name = args[1]
end

-- this is in iterator function. It is called before each insert.
-- the function should return a table for insertion or nil when there are no
-- more records to insert.
function get_value()
	return {
		key = "value", -- will be saved as string
		num = 3, -- will be saved as int
		bin = binary("some string"), -- will be saved as binary
		unum = uint(3), -- will be saved as uint
		some_bool = true, -- will be saved as bool
	}
end
