| * Reduce raw string pointers usage.Pavel Solodovnikov2018-01-311-2/+1
| | | | | | | | | | | | | | | | | | | | * Change some functions to take `std::string` instead of `const char*` in the following classes: `cmMakeFile`, `cmake`, `cmCoreTryCompile`, `cmSystemTools`, `cmState`, `cmLocalGenerator` and a few others. * Greatly reduce using of `const char*` overloads for `cmSystemTools::MakeDirectory` and `cmSystemTools::RelativePath`. * Remove many redundant `c_str()` conversions throughout the code.

* Genex: Enable COMPILE_LANGUAGE for INCLUDE_DIRECTORIES with VS and XcodeBrad King2018-01-121-28/+9
| | | | | | | | | | | | | | | The set of compile flags used for a target's C and C++ sources is based on the linker language. By default this is always the C++ flags if any C++ sources appear in the target, and otherwise the C flags. Therefore we can define the `COMPILE_LANGUAGE` generator expression in `INCLUDE_DIRECTORIES` to match the selected language. This is not exactly the same as for other generators, but is the best VS and Xcode can do. It is also sufficient for many use cases since the set of include directories for C and C++ is frequently similar but may be distinct from those for other languages like CUDA. Fixes: #17435

* Genex: Enable COMPILE_LANGUAGE for COMPILE_OPTIONS with Visual StudioBrad King2017-11-201-3/+2
| | | | | | | | | | | | | | | | | | | Since commit v3.9.0-rc4~3^2~1 (VS: Fix target_compile_options for CUDA, 2017-06-21), the evaluation of `COMPILE_LANGUAGE` receives the proper language. The set of compile flags used for a target's C and C++ sources is based on the linker language. By default this is always the C++ flags if any C++ sources appear in the target, and otherwise the C flags. Therefore we can define the `COMPILE_LANGUAGE` generator expression in `COMPILE_OPTIONS` to match the selected language. This is not exactly the same as for other generators, but is the best VS can do. It is also sufficient for many use cases since the set of allowed flags for C and C++ is almost the same in Visual Studio. Furthermore, since the VS generator moves many of the flags to declarative `.vcxproj` elements, it will automatically avoid passing C++ flags for C sources. Issue: #17435
* Genex: Enable COMPILE_LANGUAGE for file(GENERATE) with Visual StudioBrad King2017-11-171-6/+10

* Genex: Fix COMPILE_LANGUAGE messages to allow file(GENERATE) with XcodeBrad King2017-11-171-2/+2
| | | | | | | When rejecting the `COMPILE_LANGUAGE` generator expression on include directories and compile definitions with Xcode, add `file(GENERATE)` to the allowed set in the message. It is allowed and already covered by the `RunCMake.File_Generate` test `COMPILE_LANGUAGE-genex` case.
* Replace cmArray{Begin,End,Size} by their standard counterpartsMatthias Maennich2017-10-231-2/+2
| | | | | | | | | | | std::{begin,end} are part of C++11, std::{cbegin,cend} are part of C++14 and an standard compliant implementation has been introduced within the 'cm' namespace: cm::{cbegin,cend}. std::size is only part of C++17, hence exposing a compliant implementation within namespace cm (cm::size). where possible, the standard implementations are reused.

* Use C++11 override instead of CM_OVERRIDEBrad King2017-09-151-212/+212
| | | | | | | | 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'
* Meta: modernize old-fashioned loops to range-based `for`.Pavel Solodovnikov2017-09-121-24/+18
| | | | | | Changes done via `clang-tidy` with some manual fine-tuning for the variable naming and `auto` type deduction where appropriate.

* Allow OBJECT libraries to be installed, exported, and importedRobert Maynard2017-04-181-16/+27
| | | | | | | | Teach install() and export() to handle the actual object files. Disallow this on Xcode with multiple architectures because it still cannot be cleanly supported there. Co-Author: Brad King <brad.king@kitware.com>
* Genex: Allow TARGET_OBJECTS to be used everywhereRobert Maynard2017-04-181-7/+25
| | | | | | | | | Previously the `TARGET_OBJECTS` generator expression was limited only to use in a buildsystem context so that Xcode's placeholders in object file paths can be evaluated. Lift this restriction so that the expression can at least be used in most settings. Co-Author: Brad King <brad.king@kitware.com>
* Genex: Reject TARGET_OBJECTS on non-object libraries earlierBrad King2017-04-181-9/+8
| | | | | | | | Move the diagnostic that rejects the TARGET_OBJECTS generator expression in non-buildsystem context until after the check for whether the named target is an object library. This order will makes more sense than the previous order once TARGET_OBJECTS is allowed in non-buildsystem context.

* Simplify CMake per-source license noticesBrad King2016-09-271-12/+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.
* Genex: Diagnose invalid LINK_ONLY usage instead of crashingBrad King2016-09-051-3/+8
| | | | | | | | When `$<LINK_ONLY:...>` is used outside of linking we may evaluate it without a `dagChecker`. Do not dereference the NULL pointer and issue a diagnostic instead. Closes: #16287

* Avoid using KWSys auto_ptr by adopting it ourselvesBrad King2016-06-291-1/+1
| | | | | | | | | | | | Replace use of cmsys::auto_ptr with a CM_AUTO_PTR macro that maps to our own implementation adopted from the KWSys auto_ptr implementation. Later we may be able to map CM_AUTO_PTR to std::auto_ptr on compilers that do not warn about it. Automate the client site conversions: git grep -l auto_ptr -- Source/ | grep -v Source/kwsys/ | xargs sed -i \ 's|cmsys::auto_ptr|CM_AUTO_PTR|;s|cmsys/auto_ptr.hxx|cm_auto_ptr.hxx|'

* Add CM_OVERRIDE to some functionsDaniel Pfeifer2016-06-271-61/+69
| | | | | | | Run clang-tidy's modernize-use-override checker. This checker must have issues in version 3.8. It has way too little matches. And it adds override to destructors. Revert the changes on the destructors and change override to CM_OVERRIDE.
* Revise C++ coding style using clang-formatKitware Robot2016-05-161-859/+702
| | | | | | | | | | | | | 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 King2016-05-091-53/+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.
* Isolate formatted streaming blocks with clang-format off/onBrad King2016-05-061-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The clang-format tool can do a good job formatting most code, but well-organized streaming blocks are best left manually formatted. Find blocks of the form os << "...\n" "...\n" ; using the command $ git ls-files -z -- Source | egrep -v -z '^Source/kwsys/' | xargs -0 pcregrep -M --color=always -B 1 -A 1 -n \ '<<[^\n]*\n(^ *("[^\n]*("|<<|;)$|;)\n){2,}' Find blocks of the form os << "...\n" << "...\n" << "...\n"; using the command $ git ls-files -z -- Source | egrep -v -z '^Source/kwsys/' | xargs -0 pcregrep -M --color=always -B 1 -A 1 -n \ '<<[^\n]*\n(^ *<<[^\n]*(\\n"|<<|;)$\n){2,}' Surround such blocks with the pair /* clang-format off */ ... /* clang-format on */ in order to protect them from update by clang-format. Use the C-style `/*...*/` comments instead of C++-style `//...` comments in order to prevent them from ever being swallowed by re-formatting of surrounding comments.
* Format include directive blocks and ordering with clang-formatBrad King2016-04-291-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | Ensure that cmStandardIncludes.h is included before any platform header in cmGeneratorExpressionEvaluator.h. That file needs to change as a result of removal of the cmMakefile.h header from cmGeneratorExpressionNode.h, affecting the compilation of cmGeneratorExpressionNode.cxx. On AIX we need to include our own headers first to get large file support macros defined consistently within system headers. The old order in this header worked only because it was always included after other headers.
