* 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.

* 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'

| | | | | | | | | | | | | 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'
* cmConfigure: Ensure separate include block in headersDaniel Pfeifer2017-04-111-0/+1
| | | | | | | | | | | Make sure that `#include <cmConfigure.h>` is followed by an empty line in header files. This is necessary to make sure that changing <> to "" does not affect the include ordering of clang-format. Automate with: git grep -l '#include <cmConfigure.h>' | grep -v '.cxx$' \ | xargs sed -i '/#include <cmConfigure.h>/ { N; N; s/\n\{1,2\}/\n\n/ }'

* 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copyright/license notice headers that spell out copyright holder names and years are hard to maintain and often out-of-date or plain wrong.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.

* Revise C++ coding style using clang-formatKitware Robot2016-05-161-8/+3
| | | | | | | | | | | | | Run the `Utilities/Scripts/clang-format.bash` script to update all our C++ code to a new style defined by `.clang-format`. Use `clang-format` version 3.8. * 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.

* Drop builtin command documentationBrad King2013-10-161-108/+0
| | | | | Drop all GetTerseDocumentation and GetFullDocumentation methods from commands. The command documentation is now in Help/command/*.rst files.
* Remove trailing whitespace from most CMake and C/C++ codeKitware Robot2012-08-131-5/+5
| | | | | | | | | | | | | | | | | Our Git commit hooks disallow modification or addition of lines with trailing whitespace. Wipe out all remnants of trailing whitespace everywhere except third-party code. Run the following shell code: git ls-files -z -- \ bootstrap doxygen.config '*.readme' \ '*.c' '*.cmake' '*.cpp' '*.cxx' \ '*.el' '*.f' '*.f90' '*.h' '*.in' '*.in.l' '*.java' \ '*.mm' '*.pike' '*.py' '*.txt' '*.vim' | egrep -z -v '^(Utilities/cm|Source/(kwsys|CursesDialog/form)/)' | egrep -z -v '^(Modules/CPack\..*\.in)' | xargs -0 sed -i 's/ \+$//'

* Remove CMake Policy CMP0015 until it is revisedBrad King2009-10-081-4/+2
| | | | | | | | | | | | | | | | | | | | We revert commit "Create CMake Policy CMP0015 to fix set(CACHE)" because the NEW behavior of the policy breaks a valid use case: # CMakeLists.txt option(BUILD_SHARED_LIBS "..." ON) add_library(mylib ...) set(BUILD_SHARED_LIBS OFF) # we want only mylib to be shared add_subdirectory(ThirdParty) # ThirdParty/CMakeLists.txt option(BUILD_SHARED_LIBS "..." ON) # uh, oh, with NEW behavior this dir uses shared libs!!! We'll re-introduce the policy later with a different change in behavior to resolve the motivating case, which was more subtle but less common. See issue #9008.
* 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.
* Create CMake Policy CMP0015 to fix set(CACHE)Brad King2009-09-101-2/+4
| | | | | | | | The set(CACHE) and option() commands should always expose the cache value. Previously we failed to expose the value when it was already set if a local variable definition hid it. When set to NEW, this policy tells the commands to always remove the local variable definition to expose the cache value. See issue #9008.

* ENH: Add unset() command.Brad King2008-08-251-2/+3
| | | | | | | | This introduces the unset() command to make it easy to unset CMake variables, environment variables, and CMake cache variables. Previously it was not even possible to unset ENV or CACHE variables (as in completely remove them). Changes based on patch from Philip Lowman. See issue #7507.
