[sword-devel] Q about -s 4 option to osis2mod

[DM Smith]

For an uncompressed module there are 2 files per testament: an index file and a data file. There is one entry in the index file per verse in the versification. Each entry consists of a 4 byte offset and a 2 or 4 byte length. The -s flag indicates the byte size of the length. So using a -s4 will increase the size of the index file by 33%.

The data file is unchanged by the -s flag.

The compressed module is similar but has an extra set of files to indicate the block start and block size. This file does not change based upon the -s flag.

So using the -s 4 flag is not a big deal. When we build modules for the CrossWire repository we’ll use the smallest available.

Every message that osis2mod creates is found in the wiki: http://wiki.crosswire.org/Osis2mod#Messages <http://wiki.crosswire.org/Osis2mod#Messages>

There is no message for it.
