* Modernize: Use #pragma once in all header filesKitware Robot2020-09-031-4/+1
| | | | | | | | | | | | | | | | #pragma once is a widely supported compiler pragma, even though it is not part of the C++ standard. Many of the issues keeping #pragma once from being standardized (distributed filesystems, build farms, hard links, etc.) do not apply to CMake - it is easy to build CMake on a single machine. CMake also does not install any header files which can be consumed by other projects (though cmCPluginAPI.h has been deliberately omitted from this conversion in case anyone is still using it.) Finally, #pragma once has been required to build CMake since at least August 2017 (7f29bbe6 enabled server mode unconditionally, which had been using #pragma once since September 2016 (b13d3e0d)). The fact that we now require C++11 filters out old compilers, and it is unlikely that there is a compiler which supports C++11 but does not support #pragma once.
* Revise include order using clang-format-6.0Kitware Robot2019-10-011-1/+2
| | | | | Run the `clang-format.bash` script to update our C and C++ code to a new include order `.clang-format`. Use `clang-format` version 6.0.

* clang-tidy: Use `= default`Regina Pfeifer2019-01-251-1/+1
| | | | | | Suppress some cases in `Source/cmGeneratorExpressionNode.cxx` and `Source/cmUVHandlePtr.h` where a few older compilers require a user-defined default constructor (with `{}`).

| | | | | | | | | | | | Run the `clang-format.bash` script to update all our C and C++ code to a new style defined by `.clang-format`. Use `clang-format` version 6.0. * If you reached this commit for a line in `git blame`, re-run the blame operation starting at the parent of this commit to see older history for the content. * See the parent commit for instructions to rebase a change across this style transition commit.
* Use C++11 override instead of CM_OVERRIDEBrad King2017-09-151-2/+2
| | | | | | | | We now require C++11 support including `override`. Drop use of the old compatibility macro. Convert references as follows: git grep -l CM_OVERRIDE -- '*.h' '*.hxx' '*.cxx' | xargs sed -i 's/CM_OVERRIDE/override/g'
* IWYU: Mark cmConfigure.h with pragma: keepDaniel Pfeifer2017-08-261-1/+1
| | | | Also remove `#include "cmConfigure.h"` from most source files.

* Use quotes for non-system includesDaniel Pfeifer2017-04-111-1/+1
| | | | | | | | | | | | | Automate with: git grep -l '#include <cm_' -- Source \ | xargs sed -i 's/#include <\(cm_.*\)>/#include "\1"/g' git grep -l '#include <cmsys/' -- Source \ | xargs sed -i 's/#include <\(cmsys\/.*\)>/#include "\1"/g' git grep -l '#include <cm[A-Z]' -- Source \ | xargs sed -i 's/#include <\(cm[A-Z].*\)>/#include "\1"/g'

* Simplify CMake per-source license noticesBrad King2016-09-271-11/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Per-source copyright/license notice headers that spell out copyright holder names and years are hard to maintain and often out-of-date or plain wrong. Precise contributor information is already maintained automatically by the version control tool. Ultimately it is the receiver of a file who is responsible for determining its licensing status, and per-source notices are merely a convenience. Therefore it is simpler and more accurate for each source to have a generic notice of the license name and references to more detailed information on copyright holders and full license terms. Our `Copyright.txt` file now contains a list of Contributors whose names appeared source-level copyright notices. It also references version control history for more precise information. Therefore we no longer need to spell out the list of Contributors in each source file notice. Replace CMake per-source copyright/license notice headers with a short description of the license and links to `Copyright.txt` and online information available from "https://cmake.org/licensing". The online URL also handles cases of modules being copied out of our source into other projects, so we can drop our notices about replacing links with full license text. Run the `Utilities/Scripts/filter-notices.bash` script to perform the majority of the replacements mechanically. Manually fix up shebang lines and trailing newlines in a few files. Manually update the notices in a few files that the script does not handle.

* cmProcessTools: Re-arrange data layout.Stephen Kelly2015-06-071-3/+3
| | | | Size goes from 72 to 64 bytes.
* CTest: Parse empty Git commits correctlyBrad King2010-06-231-0/+1
| | | | | | | Git's diff-tree format has no '\n'-terminated blank line at the end of its commit message body block if there are no diff lines. Instead the message body is terminated by '\0' and there is no diff section. Teach CTest to parse the format in this case.
* Convert CMake to OSI-approved BSD LicenseBrad King2009-09-281-14/+9
| | | | | | | This converts the CMake license to a pure 3-clause OSI-approved BSD License. We drop the previous license clause requiring modified versions to be plainly marked. We also update the CMake copyright to cover the full development time range.
* ENH: New OutputParser::Process() signatureBrad King2009-07-101-0/+2
| | | | | | This overload accepts a null-terminated string instead of requiring a length. It is useful to pass some fake process output before and after the real process output.
* COMP: cmProcessTools::OutputParser virtual dtorBrad King2009-02-241-0/+2
| | | | | This class has virtual methods and therefore should have a virtual destructor.
* ENH: Create cmProcessTools to parse child outputBrad King2009-02-241-0/+82
This class provides a RunProcess method to run a child process and send its output to an abstract parsing interface. This also provides a simple line parser and logger implementing the parsing interface.
