Integration Omnis with Bitbucket

HI An,

I agree with Alex - we had a problem with Omnis libraries and GitHub Desktop - it seems that you need to somehow tell Bit bucket that the Omnis Library is a binary file - that way it won't try and strip CR/LF and do some sort of platform conversion.

For us, there was a settings file we needed to put in place.  In the .gitattributes file we put the following:

# Declare that .lbs files are binary
*.lbs binary

An Omnis Studio 8.1 library should begin with 35 01 01 00. You can also check a hash of the library file to see if the upload and download process changed them. On macOS run this command to get the SHA1 of a file:

Again, there may be an issue with Bitbucket working with the larger binary Omnis library files. If Bitbucket is causing problems, see if your Bitbucket admin can enable Git LFS (large file support). This might do a better job dealing with lbs files.
