# - Extract information from a subversion working copy # The module defines the following variables: # Subversion_SVN_EXECUTABLE - path to svn command line client # Subversion_VERSION_SVN - version of svn command line client # Subversion_FOUND - true if the command line client was found # If the command line client executable is found the macro # Subversion_WC_INFO( ) # is defined to extract information of a subversion working copy at # a given location. The macro defines the following variables: # _WC_URL - url of the repository (at ) # _WC_ROOT - root url of the repository # _WC_REVISION - current revision # _WC_LAST_CHANGED_AUTHOR - author of last commit # _WC_LAST_CHANGED_DATE - date of last commit # _WC_LAST_CHANGED_REV - revision of last commit # _WC_LAST_CHANGED_LOG - last log of base revision # _WC_INFO - output of command `svn info ' # Example usage: # FIND_PACKAGE(Subversion) # IF(Subversion_FOUND) # Subversion_WC_INFO(${PROJECT_SOURCE_DIR} Project) # MESSAGE("Current revision is ${Project_WC_REVISION}") # Subversion_WC_LOG(${PROJECT_SOURCE_DIR} Project) # MESSAGE("Last changed log is ${Project_LAST_CHANGED_LOG}") # ENDIF(Subversion_FOUND) # Copyright (c) 2006, Tristan Carel # All rights reserved. # Redistribution and use in source and binary forms, with or without # modification, are permitted provided that the following conditions are met: # # * Redistributions of source code must retain the above copyright # notice, this list of conditions and the following disclaimer. # * Redistributions in binary form must reproduce the above copyright # notice, this list of conditions and the following disclaimer in the # documentation and/or other materials provided with the distribution. # * Neither the name of the University of California, Berkeley nor the # names of its contributors may be used to endorse or promote products # derived from this software without specific prior written permission. # # THIS SOFTWARE IS PROVIDED BY THE REGENTS AND CONTRIBUTORS ``AS IS'' AND ANY # EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED # WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE ARE # DISCLAIMED.
