* 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.
* Graphviz: Fix issue with too many open file streams on Windows platformStephan Rohmen2020-07-311-8/+3
| | | | Fixes #20931
* Graphviz: Restore support for per-target dependency graph optionsStephan Rohmen2020-07-211-1/+35
| | | | | | | | | | | | | The behaviors controlled by options `GRAPHVIZ_GENERATE_PER_TARGET` and `GRAPHVIZ_GENERATE_DEPENDERS` were broken by commit 553658393c (Graphviz: added test suite, fixes, enhancements, 2019-10-08, v3.17.0-rc1~615^2). It had not been covered in the test suite previously, and those changes left out checks for these features from the `default_options` case. Implement the previously-existing behavior in the new graphviz generation engine added by the above-mentioned commit. Fixes: #20928
* Graphviz: added test suite, fixes, enhancementsCorentin Plouet2019-10-081-37/+56
| | | | | | | | | | | | | | | | | | | | * Added a fairly comprehensive test suite * Separated the graph traversal logic from the Graphviz generation code by introducing a new class, cmLinkItemsGraphVisitor{.h,cxx} * Made the graph traversal logic less ad-hoc by using existing methods in the GlobalGenerator; this fixed a few bugs * Added support for new target types: custom targets, object and unknown libraries * Improved support for ALIAS libraries by showing the alias(es) in the graph * Introduced new flags to control those new libraries (consistent with existing flags) * Updated the documentation * Removed useless setting to set graph type in dot file * Improved the node/edge shapes (nicer, more consistent) * Added a legend to the graph * Some refactoring and cleanup of the Graphviz generation code * Added test and fix for issue 19746
* Revise include order using clang-format-6.0Kitware Robot2019-10-011-3/+4
| | | | | 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.

* graphviz: dereference ALIAS targetsNick Schultz2018-10-261-1/+3
| | | | | | | Previous behavior treats ALIAS targets as external targets. This fix de-aliases these targets to their pointed target. Fixes: #15636
* cmGraphVizWriter: Updated to create and follow dependers for interface targetsJoel T. Frederico2017-12-141-0/+1
| | | | | Generating graphs of dependencies now uses interface targets, but graphs of dependers did not include interface targets.

* 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.
* fix a load of include-what-you-use violationsDaniel Pfeifer2016-09-031-4/+8

* Revise C++ coding style using clang-formatKitware Robot2016-05-161-2/+0
| | | | | | | | | | | | | 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.
* Format include directive blocks and ordering with clang-formatBrad King2016-04-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sort include directives within each block (separated by a blank line) in lexicographic order (except to prioritize `sys/types.h` first). First run `clang-format` with the config file: --- SortIncludes: false ... Commit the result temporarily. Then run `clang-format` again with: --- SortIncludes: true IncludeCategories: - Regex: 'sys/types.h' Priority: -1 ... Commit the result temporarily. Start a new branch and cherry-pick the second commit. Manually resolve conflicts to preserve indentation of re-ordered includes. This cleans up the include ordering without changing any other style. Use the following command to run `clang-format`: $ git ls-files -z -- \ '*.c' '*.cc' '*.cpp' '*.cxx' '*.h' '*.hh' '*.hpp' '*.hxx' | egrep -z -v '(Lexer|Parser|ParserHelper)\.' | egrep -z -v '^Source/cm_sha2' | egrep -z -v '^Source/(kwsys|CursesDialog/form)/' | egrep -z -v '^Utilities/(KW|cm).*/' | egrep -z -v '^Tests/Module/GenerateExportHeader' | egrep -z -v '^Tests/RunCMake/CommandLine/cmake_depends/test_UTF-16LE.h' | xargs -0 clang-format -i This selects source files that do not come from a third-party.

* Source: Stabilize include orderBrad King2016-04-291-2/+4
| | | | | Each source file has a logical first include file. Include it in an isolated block so that tools that sort includes do not move them.

* cmState: Move TargetType enum from cmTarget.Stephen Kelly2015-10-141-1/+1
| | | | | | | Mostly automated: values=( "EXECUTABLE" "STATIC_LIBRARY" "SHARED_LIBRARY" "MODULE_LIBRARY" "OBJECT_LIBRARY" "UTILITY" "GLOBAL_TARGET" "INTERFACE_LIBRARY" "UNKNOWN_LIBRARY" "TargetType") for i in "${values[@]}"; do git grep -l cmTarget::$i | xargs sed -i "s|cmTarget::$i|cmState::$i|g"; done
* cmGraphVizWriter: Re-arrange data layout.Stephen Kelly2015-06-071-8/+7
| | | | Size goes from 272 to 264 bytes.
* strings: Remove cmStdString referencesBen Boeckel2014-03-081-6/+6
| | | | | | | | | | | Casts from std::string -> cmStdString were high on the list of things taking up time. Avoid such implicit casts across function calls by just using std::string everywhere. The comment that the symbol name is too long is no longer relevant since modern debuggers alias the templates anyways and the size is a non-issue since the underlying methods are generated since it's inherited.

* graphviz: allow to disable per target graphs (#14746)Daniel Pfeifer2014-02-101-0/+2
| | | | | | | In CMakeGraphVizOptions.cmake, allow the options GRAPHVIZ_GENERATE_PER_TARGET and GRAPHVIZ_GENERATE_DEPENDERS to enable the generation of per target graphs and subgraphs respectively. Both options are TRUE per default to maintain current behavior.
* Also generate dependers-graphviz files.Alex Neundorf2011-02-061-0/+6
| | | | | | | | | | | With this commit, the --graphviz option now also generates dot files which show which other targets depend on some target. So, now there is * a global dot-file which shows all targets and dependencies * a dot file which shows on what a target Foo depends * a dot file which shows which other targets depend on Foo Alex
* GRAPHVIZ_IGNORE_TARGETS is now a list of regular expressionsAlex Neundorf2011-02-051-3/+1
| | | | | | | | | This is similar e.g. to CTEST_CUSTOM_WARNING_EXCEPTION from ctest. GRAPHVIZ_TARGET_IGNORE_REGEX is not supported anymore. I hope this is ok, since this was 100% undocumented and can't break a build. Alex
* Make it possible to exlude external libs from dot filesAlex Neundorf2011-02-051-0/+1
| | | | | | | | | Patch from Christian Ehrlicher. By setting GRAPHVIZ_EXTERNAL_LIBS to TRUE in CMakeGraphVizOptions.cmake you can now exclude external libraries from the produced dot file. I.e. then you see only the dependencies within your project. Alex
* Exclude targets from the graphviz file based on a regexAlex Neundorf2010-11-141-1/+1
| | | | | | | | | This commit adds support for a GRAPHVIZ_TARGET_IGNORE_REGEX variable which can be set() in CMakeGraphVizOptions.cmake. Targets matching this regex will be skipped when generating the graphviz graphs. Alex
* Collect targets and libs on demand instead of in the ctorAlex Neundorf2010-11-141-2/+8
| | | | | | | This is necessary for the next commit which requires that the targets are collected after the settings have been read. Alex
* Use std::cout instead of fprintfAlex Neundorf2010-11-141-2/+2
| | | | Alex
* Enable/disable generating graphs depending on the target typeAlex Neundorf2010-11-141-0/+8
| | | | | | | | | In CMakeGraphVizOptions.cmake you can now set GRAPHVIZ_EXECUTABLES, GRAPHVIZ_STATIC_LIBS, GRAPHVIZ_SHARED_LIBS and GRAPHVIZ_MODULE_LIBS to TRUE or FALSE depending on whether you want graphs for the targets of the respective types. Alex
* Move the code for generating dot-files into separate class cmGraphVizWriterAlex Neundorf2010-11-091-0/+70
