CONTRIBUTING.rst

+Contributing to KWSys
+*********************
+
+Patches
+=======
+
+KWSys is kept in its own Git repository and shared by several projects
+via copies in their source trees.  Changes to KWSys should not be made
+directly in a host project, except perhaps in maintenance branches.
+
+KWSys uses `Kitware's GitLab Instance`_ to manage development and code review.
+To contribute patches:
+
+#. Fork the upstream `KWSys Repository`_ into a personal account.
+#. Base all new work on the upstream ``master`` branch.
+#. Run ``./SetupForDevelopment.sh`` in new local work trees.
+#. Create commits making incremental, distinct, logically complete changes.
+#. Push a topic branch to a personal repository fork on GitLab.
+#. Create a GitLab Merge Request targeting the upstream ``master`` branch.
+
+Once changes are reviewed, tested, and integrated to KWSys upstream then
+copies of KWSys within dependent projects can be updated to get the changes.
+

+
+Code Style
+==========
+
+We use `clang-format`_ version **18** to define our style for C++ code in
+the KWSys source tree.  See the `.clang-format`_ configuration file for
+our style settings.  Use the `clang-format.bash`_ script to format source
+code.  It automatically runs ``clang-format`` on the set of source files
+for which we enforce style.  The script also has options to format only
+a subset of files, such as those that are locally modified.

+/** \class CommandLineArguments
+ * \brief Command line arguments processing code.
+ *
+ * Find specified arguments with optional options and execute specified methods
+ * or set given variables.
+ *
+ * The two interfaces it knows are callback based and variable based. For
+ * callback based, you have to register callback for particular argument using
+ * AddCallback method. When that argument is passed, the callback will be
+ * called with argument, value, and call data. For boolean (NO_ARGUMENT)
+ * arguments, the value is "1". If the callback returns 0 the argument parsing
+ * will stop with an error.
+ *
+ * For the variable interface you associate variable with each argument. When
+ * the argument is specified, the variable is set to the specified value casted
+ * to the appropriate type. For boolean (NO_ARGUMENT), the value is "1".
+ *
+ * Both interfaces can be used at the same time.
+ *
+ * Possible argument types are:
+ *   NO_ARGUMENT     - The argument takes no value             : --A
+ *   CONCAT_ARGUMENT - The argument takes value after no space : --Aval
+ *   SPACE_ARGUMENT  - The argument takes value after space    : --A val
+ *   EQUAL_ARGUMENT  - The argument takes value after equal    : --A=val
+ *   MULTI_ARGUMENT  - The argument takes values after space   : --A val1 val2
+ * val3 ...
+ *
+ * Example use:
+ *
+ * kwsys::CommandLineArguments arg;
+ * arg.Initialize(argc, argv);
+ * typedef kwsys::CommandLineArguments argT;
+ * arg.AddArgument("--something", argT::EQUAL_ARGUMENT, &some_variable,
+ *                 "This is help string for --something");
+ * if ( !arg.Parse() )
+ *   {
+ *   std::cerr << "Problem parsing arguments" << std::endl;
+ *   res = 1;
+ *   }
+ *

+ * DynamicLoader provides a portable interface to loading dynamic
+ * libraries or dll's into a process.
+ *
+ * Directory currently works with Windows, Apple, HP-UX and Unix (POSIX)
+ * operating systems
+ *
+ * \warning dlopen on *nix system works the following way:
+ * If filename contains a slash ("/"), then it is interpreted as a (relative
+ * or absolute) pathname.  Otherwise, the dynamic linker searches for the
+ * library as follows : see ld.so(8) for further details):
+ * Whereas this distinction does not exist on Win32. Therefore ideally you
+ * should be doing full path to guarantee to have a consistent way of dealing
+ * with dynamic loading of shared library.
+ *
+ * \warning the Cygwin implementation do not use the Win32 HMODULE. Put extra
+ * condition so that we can include the correct declaration (POSIX)
