* 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copyright/license notice headers that spell out copyright holder names and years are hard to maintain and often out-of-date or plain wrong.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 Robot2016-05-161-56/+32
| | | | | | | | | | | | | 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 `//------...` horizontal separator commentsBrad King2016-05-091-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | Modern editors provide plenty of ways to visually separate functions. Drop the explicit comments that previously served this purpose. Use the following command to automate the change: $ git ls-files -z -- \ "*.c" "*.cc" "*.cpp" "*.cxx" "*.h" "*.hh" "*.hpp" "*.hxx" | egrep -z -v "^Source/cmCommandArgumentLexer\." | egrep -z -v "^Source/cmCommandArgumentParser(\.y|\.cxx|Tokens\.h)" | egrep -z -v "^Source/cmDependsJavaLexer\." | egrep -z -v "^Source/cmDependsJavaParser(\.y|\.cxx|Tokens\.h)" | egrep -z -v "^Source/cmExprLexer\." | egrep -z -v "^Source/cmExprParser(\.y|\.cxx|Tokens\.h)" | egrep -z -v "^Source/cmFortranLexer\." | egrep -z -v "^Source/cmFortranParser(\.y|\.cxx|Tokens\.h)" | egrep -z -v "^Source/cmListFileLexer\." | egrep -z -v "^Source/cm_sha2" | egrep -z -v "^Source/(kwsys|CursesDialog/form)/" | egrep -z -v "^Utilities/(KW|cm).*/" | xargs -0 sed -i '/^\(\/\/---*\|\/\*---*\*\/\)$/ {d;}' This avoids modifying third-party sources and generated sources.
* Port all cmOStringStream to std::ostringstream.Stephen Kelly2015-01-111-3/+3
| | | | All compilers hosting CMake support the std class.
* cmCMakeMinimumRequired: Use unsigned int for version numbersChristoph Grüninger2014-12-231-8/+8

* Remove c_str calls when using stream APIs.Stephen Kelly2014-03-111-2/+2
| | | | | Use an ad-hoc clang tool for matching the calls which should be ported.
* Remove some c_str() calls.Stephen Kelly2014-03-111-2/+2
| | | | | | Use the clang RemoveCStrCalls tool to automatically migrate the code. This was only run on linux, so does not have any positive or negative effect on other platforms.
* Drop compatibility with CMake < 2.4Brad King2013-10-231-0/+3
| | | | | | | | | | | | Drop all behavior activated by setting CMAKE_BACKWARDS_COMPATIBILITY to a value lower than 2.4, and generate an error when projects or the user attempt to do so. In the error suggest using a CMake 2.8.x release. Teach cmake_minimum_required to warn about projects that do not require at least CMake 2.4. They are not supported by CMake >= 3.0. Replace the documentation of CMAKE_BACKWARDS_COMPATIBILITY with a reference to policy CMP0001.
* Remove trailing whitespace from most CMake and C/C++ codeKitware Robot2012-08-131-1/+1
| | | | | | | | | | | | | | | | | 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/ \+$//'
* Teach cmake_minimum_required about tweak versionBrad King2010-04-231-6/+13
| | | | | | | | The command now accepts four version components in the format major[.minor[.patch[.tweak]]] This corresponds to the new versioning scheme introduced recently.
* 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.
* Add parentheses around '&&' between '||' for gccBrad King2009-09-111-7/+7
| | | | | | | The GNU compiler warns about possible operator precedence mistakes and asks for explicit parentheses (-Wparentheses). We add the parentheses to silence the warning. This also fixes one real logic error in the find_package() implementation by correcting expression evaluation order.
* ENH: Ignore unknown cmake_minimum_required argsBrad King2009-01-031-5/+21
| | | | | | | When cmake_minimum_required is called with an unknown argument it should not complain about it if the version specified is in the future. This allows the proper error to be shown about the current CMake being too old.
* ENH: Cleanup policy version interface presented to user.Brad King2008-03-241-6/+5
