# FindSubversion | |
# -------------- | |
# | |
# 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 | |
# SUBVERSION_FOUND - same as Subversion_FOUND, set for compatibility reasons | |
# | |
# | |
# | |
# The minimum required version of Subversion can be specified using the | |
# standard syntax, e.g. find_package(Subversion 1.4) | |
# | |
# If the command line client executable is found two macros are defined: | |
# | |
# :: | |
# | |
# Subversion_WC_INFO(<dir> <var-prefix>) | |
# Subversion_WC_LOG(<dir> <var-prefix>) | |
# | |
# Subversion_WC_INFO extracts information of a subversion working copy | |
# at a given location. This 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_INFO - output of command `svn info <dir>' | |
# | |
# Subversion_WC_LOG retrieves the log message of the base revision of a | |
# subversion working copy at a given location. This macro defines the | |
# variable: | |
# | |
# :: | |
# | |
# <var-prefix>_LAST_CHANGED_LOG - last log of base revision | |
# | |
# 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() | |
