# - 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(<dir> <var-prefix>)
|
||
|
|
# is defined to extract information of a subversion working copy at
|
||
|
|
# a given location. The macro defines the following variables:
|
||
|
|
# <var-prefix>_WC_URL - url of the repository (at <dir>)
|
||
|
|
# <var-prefix>_WC_ROOT - root url of the repository
|
||
|
|
# <var-prefix>_WC_REVISION - current revision
|
||
|
|
# <var-prefix>_WC_LAST_CHANGED_AUTHOR - author of last commit
|
||
|
|
# <var-prefix>_WC_LAST_CHANGED_DATE - date of last commit
|
||
|
|
# <var-prefix>_WC_LAST_CHANGED_REV - revision of last commit
|
||
|
|
# <var-prefix>_WC_LAST_CHANGED_LOG - last log of base revision
|
||
|
|
# <var-prefix>_WC_INFO - output of command `svn info <dir>'
|
||
|
|
# Example usage:
|
||
|
|
# FIND_PACKAGE(Subversion)
|
||
|
|
# IF(Subversion_FOUND)
|
||
|
|
# Subversion_WC_INFO(${PROJECT_SOURCE_DIR} Project)
