| <p>Extract information from a subversion working copy</p> |
| <p>The module defines the following variables:</p> |
| <div class="highlight-none notranslate"><div class="highlight"><pre><span></span>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 |
| </pre></div> |
| </div> |
| <p>The minimum required version of Subversion can be specified using the |
| standard syntax, e.g. <code class="docutils literal notranslate"><span class="pre">find_package(Subversion</span> <span class="pre">1.4)</span></code>.</p> |
| <p>If the command line client executable is found two macros are defined:</p> |
| <div class="highlight-none notranslate"><div class="highlight"><pre><span></span>Subversion_WC_INFO(<dir> <var-prefix> [IGNORE_SVN_FAILURE]) |
| Subversion_WC_LOG(<dir> <var-prefix>) |
| </pre></div> |
| </div> |
| <p><code class="docutils literal notranslate"><span class="pre">Subversion_WC_INFO</span></code> extracts information of a subversion working copy at a |
| given location. This macro defines the following variables if running |
| Subversion's <code class="docutils literal notranslate"><span class="pre">info</span></code> command on <code class="docutils literal notranslate"><span class="pre"><dir></span></code> succeeds; otherwise a |
| <code class="docutils literal notranslate"><span class="pre">SEND_ERROR</span></code> message is generated.</p> |
| <div class="versionadded"> |
| <p><span class="versionmodified added">New in version 3.13: </span>The error can be ignored by providing the |
| <code class="docutils literal notranslate"><span class="pre">IGNORE_SVN_FAILURE</span></code> option, which causes these variables to remain |
| undefined.</p> |
| </div> |
| <div class="highlight-none notranslate"><div class="highlight"><pre><span></span><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>' |
| </pre></div> |
| </div> |
| <p><code class="docutils literal notranslate"><span class="pre">Subversion_WC_LOG</span></code> retrieves the log message of the base revision of a |
| subversion working copy at a given location. This macro defines the variable:</p> |
| <div class="highlight-none notranslate"><div class="highlight"><pre><span></span><var-prefix>_LAST_CHANGED_LOG - last log of base revision |
| </pre></div> |
| </div> |
| <p>Example usage:</p> |
| <div class="highlight-none notranslate"><div class="highlight"><pre><span></span>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}") |
