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> [IGNORE_SVN_FAILURE])
|
||
|
|
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 if running
|
||
|
|
Subversion's ``info`` command on ``<dir>`` succeeds; otherwise a
|
||
|
|
``SEND_ERROR`` message is generated. The error can be ignored by providing the
|
||
|
|
``IGNORE_SVN_FAILURE`` option, which causes these variables to remain
|
||
|
|
undefined.
|
||
|
|
|
||
|
|
::
|
||
|
|
|
||
|
|
<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()
