I want to use the SVN synchronization in BBedit (version 10.0) for project developed in Lua language. Should I download a SVN plugin (if yes, from where?) or BBEedit has it (if yes, in which menu is it?) Thanks.
It has Subversion support:
From http://www.barebones.com/products/bbedit/benefitsintegrate.html#SourceManagement
Direct integration with Subversion: BBEdit’s Subversion menu includes all of the commands that you need for common operations. In addition, when committing from within BBEdit, a handy submission form makes it easy to write commit comments.
Note also, from http://pine.barebones.com/manual/BBEdit_10_User_Manual.pdf
In order to enable BBEdit’s Subversion integration, you must have Subversion 1.1 or later installed and available in the PATH for GUI applications (as controlled by ~/.MacOSX/ environment.plist). You must also have a Subversion working copy which has been checked out via the command line.
