FindSubversion
--------------
Extract information from a subversion working copy
This module finds a Subversion command-line client executable (``svn``) and
provides macros for extracting information from a Subversion working copy.
The module defines the following variables:
Result Variables
^^^^^^^^^^^^^^^^
::
This 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
``Subversion_FOUND``
True if the Subversion command-line client was found. For backward
compatibility, the ``SUBVERSION_FOUND`` variable is also set to the same
value.
``Subversion_VERSION_SVN``
Version of the ``svn`` command-line client.
Cache Variables
^^^^^^^^^^^^^^^
The minimum required version of Subversion can be specified using the
standard syntax, e.g. ``find_package(Subversion 1.4)``.
The following cache variables may also be set:
If the command line client executable is found two macros are defined:
``Subversion_SVN_EXECUTABLE``
Path to the ``svn`` command-line client.
.. code-block:: cmake
Macros
^^^^^^
Subversion_WC_INFO(<dir> <var-prefix> [IGNORE_SVN_FAILURE])
Subversion_WC_LOG(<dir> <var-prefix>)
If the Subversion command-line client is found, the following macros are
defined:
``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.
.. command:: Subversion_WC_INFO
.. versionadded:: 3.13
The error can be ignored by providing the
``IGNORE_SVN_FAILURE`` option, which causes these variables to remain
undefined.
Extracts information from a Subversion working copy located at a specified
directory:
::
.. code-block:: cmake
<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_INFO(<dir> <var-prefix> [IGNORE_SVN_FAILURE])
``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:
This macro defines the following variables if running Subversion's ``info``
subcommand on ``<dir>`` succeeds; otherwise a ``SEND_ERROR`` message is
generated:
::
``<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 the command ``svn info <dir>``
<var-prefix>_LAST_CHANGED_LOG - last log of base revision
The options are:
``IGNORE_SVN_FAILURE``
.. versionadded:: 3.13
When specified, errors from Subversion operation will not trigger a
``SEND_ERROR`` message. In case of an error, the ``<var-prefix>_*``
variables remain undefined.
.. command:: Subversion_WC_LOG
Retrieves the log message of the base revision of a Subversion working copy at
a given location:
.. code-block:: cmake
Subversion_WC_LOG(<dir> <var-prefix>)
This macro defines the following variable if running Subversion's ``log``
subcommand on ``<dir>`` succeeds; otherwise a ``SEND_ERROR`` message is
generated:
``<var-prefix>_LAST_CHANGED_LOG``
Last log of the base revision of a Subversion working copy located at
``<dir>``.
Examples
^^^^^^^^
Example usage:
.. code-block:: cmake
find_package(Subversion)
if(SUBVERSION_FOUND)
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()
The minimum required version of Subversion can be specified using the standard
syntax:
.. code-block:: cmake
find_package(Subversion 1.4)
