# - Extract information from a subversion working copy # The module defines the following variables: # Mercurial_HG_EXECUTABLE - path to hg command line client # Mercurial_VERSION_HG - version of hg command line client # Mercurial_FOUND - true if the command line client was found # MERCURIAL_FOUND - same as Mercurial_FOUND, set for compatiblity reasons # # The minimum required version of Mercurial can be specified using the # standard syntax, e.g. FIND_PACKAGE(Mercurial 1.4) # # If the command line client executable is found two macros are defined: # Mercurial_WC_INFO(<dir> <var-prefix>) # Mercurial_WC_LOG(<dir> <var-prefix>) # Mercurial_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 `hg info <dir>' # Mercurial_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(Mercurial) # IF(MERCURIAL_FOUND) # Mercurial_WC_INFO(${PROJECT_SOURCE_DIR} Project) # MESSAGE("Current revision is ${Project_WC_REVISION}") # Mercurial_WC_LOG(${PROJECT_SOURCE_DIR} Project) # MESSAGE("Last changed log is ${Project_LAST_CHANGED_LOG}") # ENDIF(MERCURIAL_FOUND) #============================================================================= # Copyright 2006-2009 Kitware, Inc. # Copyright 2006 Tristan Carel # # Distributed under the OSI-approved BSD License (the "License"); # see accompanying file Copyright.txt for details. # # This software is distributed WITHOUT ANY WARRANTY; without even the # implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. # See the License for more information. #============================================================================= # (To distribute this file outside of CMake, substitute the full # License text for the above reference.)
