* 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 Robot2019-10-011-0/+1
| | | | | 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.
* cmExecutionStatus: Remove function ClearRegina Pfeifer2019-08-061-9/+0

* cmCommand: deprecate functions GetMakefile and SetErrorDaniel Pfeifer2019-07-211-0/+19
| | | | | | | | | Replace the members for the Makefile and the Error with a cmExecutionStatus. Re-implement GetMakefile and SetError based on that. Both functions should be called directly on the cmExecutionStatus that is passed to InitialPass. This will help us make all Commands immutable and remove the need for cloning.

* 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 `{}`).

* cmExecutionStatus: Remove arguments from settersDaniel Pfeifer2017-05-091-12/+19
| | | | | The setters are only used to set boolean values. The values are never reset individually.

* 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copyright/license notice headers that spell out copyright holder names and years are hard to maintain and often out-of-date or plain wrong.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.
* cmMakefile: Restore nested error logic use of cmExecutionStatusBrad King2016-09-061-0/+4
| | | | | | | | | | | | | | Since commit 14a8d61f (cmMakefile: Port nested error logic away from cmExecutionStatus) we fail to continue processing function and macro bodies after non-fatal errors. A non-fatal error should not stop foreach loops, macro bodies, nested bodies, or the outer script. Add a test covering these cases, and revert the change to fix them. Also revert commit 2af853de (cmMakefile: Simplify IssueMessage implementation) because the assertion it added (which was removed by the above commit and is restored by reverting it) is incorrect. We do have code paths that call cmMakefile::IssueMessage with an empty execution stack, such as in CheckForUnusedVariables's LogUnused call.

* Revise C++ coding style using clang-formatKitware Robot2016-05-161-14/+8
| | | | | | | | | | | | | 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.

* Remove extra semicolons from C++ code.Stephen Kelly2014-04-031-1/+1
| | | | | Clang based tools running over the code complain about these, but clang has a fixit for removing them.
* Remove trailing whitespace from most CMake and C/C++ codeKitware Robot2012-08-131-7/+7
| | | | | | | | | | | | | | | | | 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/ \+$//'
* 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 format for warning and error messagesBrad King2008-03-071-1/+8
| | | | | | | | | | | | | - Add cmMakefile methods IssueError and IssueWarning - Maintain an explicit call stack in cmMakefile - Include context/call-stack info in messages - Nested errors now unwind the call stack - Use new mechanism for policy warnings and errors - Improve policy error message - Include cmExecutionStatus pointer in call stack so that errors deeper in the C++ stack under a command invocation will become errors for the command
* ENH: add return and break support to cmake, also change basic command ↵Ken Martin2008-01-231-0/+53
invocation signature to be able to return extra informaiton via the cmExecutionStatus class
