Words Of Worship Song File Format
|
||||
`````````````````````````````````
|
||||
|
||||
The Words Of Worship song file format is as follows:
|
||||
|
||||
* The song title is the file name minus the extension.
|
||||
* The song has a header, a number of blocks, followed by footer containing
|
||||
the author and the copyright.
|
||||
* A block can be a verse, chorus or bridge.
|
||||
|
||||
File Header:
|
||||
Bytes are counted from one, i.e. the first byte is byte 1. These bytes,
|
||||
up to the 56 byte, can change but no real meaning has been found. The
|
||||
56th byte specifies how many blocks there are. The first block starts
|
||||
with byte 83 after the "CSongDoc::CBlock" declaration.
|
||||
|
||||
Blocks:
|
||||
Each block has a starting header, some lines of text, and an ending
|
||||
footer. Each block starts with 4 bytes, the first byte specifies how
|
||||
many lines are in that block, the next three bytes are null bytes.
|
||||
|
||||
Each block ends with 4 bytes, the first of which defines what type of
|
||||
block it is, and the rest which are null bytes:
|
||||
|
||||
* ``NUL`` (\x00) - Verse
|
||||
* ``SOH`` (\x01) - Chorus
|
||||
* ``STX`` (\x02) - Bridge
|
||||
|
||||
Blocks are seperated by two bytes. The first byte is ``SOH`` (\x01),
|
||||
and the second byte is ``€`` (\x80).
|
||||
|
||||
Lines:
|
||||
Each line starts with a byte which specifies how long that line is,
|
||||
the line text, and ends with a null byte.
|
||||
|
||||
|
||||
Footer:
|
||||
The footer follows on after the last block, the first byte specifies
|
||||
the length of the author text, followed by the author text, if
|
||||
this byte is null, then there is no author text. The byte after the
|
||||
author text specifies the length of the copyright text, followed
|
||||
by the copyright text.
|
||||
|
||||
The file is ended with four null bytes.
|
||||
|
||||
Valid extensions for a Words of Worship song file are:
|
||||
|
||||
* .wsg
|
||||
* .wow-song
