1 # - Extract information from a subversion working copy
2 # The module defines the following variables:
3 # Subversion_SVN_EXECUTABLE - path to svn command line client
4 # Subversion_VERSION_SVN - version of svn command line client
5 # Subversion_FOUND - true if the command line client was found
6 # SUBVERSION_FOUND - same as Subversion_FOUND, set for compatiblity reasons
8 # The minimum required version of Subversion can be specified using the
9 # standard syntax, e.g. find_package(Subversion 1.4)
11 # If the command line client executable is found two macros are defined:
12 # Subversion_WC_INFO(<dir> <var-prefix>)
13 # Subversion_WC_LOG(<dir> <var-prefix>)
14 # Subversion_WC_INFO extracts information of a subversion working copy at
15 # a given location. This macro defines the following variables:
16 # <var-prefix>_WC_URL - url of the repository (at <dir>)
17 # <var-prefix>_WC_ROOT - root url of the repository
18 # <var-prefix>_WC_REVISION - current revision
19 # <var-prefix>_WC_LAST_CHANGED_AUTHOR - author of last commit
20 # <var-prefix>_WC_LAST_CHANGED_DATE - date of last commit
21 # <var-prefix>_WC_LAST_CHANGED_REV - revision of last commit
22 # <var-prefix>_WC_INFO - output of command `svn info <dir>'
23 # Subversion_WC_LOG retrieves the log message of the base revision of a
24 # subversion working copy at a given location. This macro defines the
26 # <var-prefix>_LAST_CHANGED_LOG - last log of base revision
28 # find_package(Subversion)
29 # if(SUBVERSION_FOUND)
30 # Subversion_WC_INFO(${PROJECT_SOURCE_DIR} Project)
31 # message("Current revision is ${Project_WC_REVISION}")
32 # Subversion_WC_LOG(${PROJECT_SOURCE_DIR} Project)
33 # message("Last changed log is ${Project_LAST_CHANGED_LOG}")
