* Revise C++ coding style using clang-formatKitware Robot2016-05-161-32/+31
| | | | | | | | | | | | | 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.
* genex: remove the need for backtracesBen Boeckel2014-06-051-0/+5
| | | | | Rather than making dummy backtraces and passing them around, just make backtraces optional.
* cmTarget: Transitively evaluate compiler features.Stephen Kelly2014-04-071-1/+2
| | | | | | | | | | | Extend the interface of the target_compile_features command with PUBLIC and INTERFACE keywords. Populate the INTERFACE_COMPILER_FEATURES target property if they are set. Consume the INTERFACE_COMPILER_FEATURES target property from linked dependent targets to determine the final required compiler features and the compile flag, if needed. Use the same pattern of origin-debugging which is used for other build properties.
* cmTarget: Allow transitive evaluation of SOURCES property.Stephen Kelly2014-04-021-1/+4
| | | | | | | Extend the cmGeneratorExpressionDAGChecker with an interface returning the name of the top target. Use that to determine when there is a DAG violation, as required by the RunCMake.Languages tests.
* strings: Remove cmStdString referencesBen Boeckel2014-03-081-1/+1
| | | | | | | | | | | 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.
* Genex: Fix case of methods in the dag checker.Stephen Kelly2014-01-061-3/+3

* Genex: Use a preprocessor loop to implement transitive DAG check.Stephen Kelly2014-01-061-0/+4
| | | | | | | | | The other infrastructure for transitive property handling is already using a preprocessor loop. Implement special backward-compatibility handling of COMPILE_DEFINITIONS_<CONFIG> using a template switch for the extra check.
* Genex: List transitive properties and methods as a table, not two lists.Stephen Kelly2014-01-061-10/+12
| | | | Introduce a new set of macros to select the column.
* Undefine local preprocessor loop variables.Stephen Kelly2014-01-061-1/+3
| | | | | Most occurances of this pattern already contain the undef, so add it to the rest too.
* QtAutoUic: Add INTERFACE_AUTOUIC_OPTIONS target property.Stephen Kelly2013-11-271-2/+4
| | | | | | | | | | | | | | | | | | | | Transitively consume the property from linked dependents. Implement configuration-specific support by following the pattern set out for compile definitions and includes in cmQtAutoGenerators. Implement support for origin-tracking with CMAKE_DEBUG_TARGET_PROPERTIES. This is motivated by the needs of KDE, which provides a separate translation system based on gettext instead of the Qt linguist translation system. The Qt uic tool provides command line options for configuring the method used to translate text, and to add an include directive to the generated file to provide the method. http://thread.gmane.org/gmane.comp.kde.devel.frameworks/7930/focus=7992 Implement the interface to provide the uic options as a usage-requirement on the KI18n target, as designed for KDE.
* Genex: Simplify the preprocessor looper for interface properties.Stephen Kelly2013-11-091-4/+4
| | | | By removing the INTERFACE_ prefix, we can use this in more contexts.
* Merge topic 'tid-system-argument'Brad King2013-07-161-0/+2
|\ | | | | | | | | | | | | | | | | | | 9cf3547 Add the INTERFACE_SYSTEM_INCLUDE_DIRECTORIES target property. 1925cff Add a SYSTEM parameter to target_include_directories (#14180) 286f227 Extend the cmTargetPropCommandBase interface property handling. 83498d4 Store system include directories in the cmTarget. f1fcbe3 Add Target API to determine if an include is a system include. 2679a34 Remove unused variable.
| * Add the INTERFACE_SYSTEM_INCLUDE_DIRECTORIES target property.Stephen Kelly2013-07-161-0/+2
| | | | | | | | | | | | | | | | Unlike other target properties, this does not have a corresponding non-INTERFACE variant. This allows propagation of system attribute on include directories from link dependents.
* | Introduce the LINK_ONLY generator expression.Stephen Kelly2013-07-071-0/+5
|/ | | | | This is an internal expression for use by target_link_libraries for static libraries.
* Genex: Extend EvaluatingLinkLibraries to also check the top target name.Stephen Kelly2013-06-241-1/+1
| | | | | This will allow testing whether we are evaluating the link libraries of a particular target.
* Use a preprocessor loop to manage the valid transitive properties.Stephen Kelly2013-06-101-3/+15
| | | | | Hopefully this will prevent regressions when adding further transitive properties in the future.
* Add COMPILE_OPTIONS target property.Stephen Kelly2013-06-021-0/+1
| | | | | | This method reads generator expressions from the COMPILE_OPTIONS target property, as well as INTERFACE_COMPILE_OPTIONS from linked dependents.
* Fix constness of accessors.Stephen Kelly2013-02-231-2/+2

* Optimize genex evaluation for includes and defines.Stephen Kelly2013-02-021-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | While porting boost to use these features, the generation step took too long (several minutes before I stopped it). The reason was that the boost libraries form a large interdependent mesh. The libraries list their dependencies in their INTERFACE such as: $<LINKED:boost::core>;$<LINKED:boost::config>;$<LINKED:boost::mpl> As boost::core already depends on the boost::config libraries, that expression has no impact on the end-content, as it is removed after the generation step. There is no DAG issue though, so the generator expression evaluation would fully evaluate them. In the case of the config library, it also depends on the core library, so all depends are followed through that again, despite the fact that they've just been evaluated. After this patch, the evaluation skips libraries if they have already been seen via depends or directly in the content. This patch keeps track of targets whose INTERFACE has been consumed already. The INCLUDE_DIRECTORIES and COMPILE_DEFINITIONS properties are whitelisted because repeated content will be stripped out later during generation. For other properties now and in the future, that may not be the case.
* Add API to check if we're reading a includes or defines property.Stephen Kelly2013-01-311-0/+2
| | | | This will allow the implementation of the LINKED generator expression.
* Make INTERFACE determined properties readable in generator expressions.Stephen Kelly2013-01-201-0/+3
| | | | | The properties are evaluated as link-dependent interface properties when evaluating the generator expressions.
* Make cycles in target properties ignored, not an error.Stephen Kelly2013-01-051-3/+9
| | | | | | | | | | | | | | | | Constructs such as these are an error as they are direct self-references: set_property(TARGET foo APPEND PROPERTY INCLUDE_DIRECTORIES $<TARGET_PROPERTY:foo,INCLUDE_DIRECTORIES>) set_property(TARGET foo APPEND PROPERTY INCLUDE_DIRECTORIES $<TARGET_PROPERTY:INCLUDE_DIRECTORIES>) However, this is an indirect self-reference in a cycle, and not an error: set_property(TARGET foo APPEND PROPERTY INCLUDE_DIRECTORIES $<TARGET_PROPERTY:bar,INCLUDE_DIRECTORIES>) set_property(TARGET bar APPEND PROPERTY INCLUDE_DIRECTORIES $<TARGET_PROPERTY:foo,INCLUDE_DIRECTORIES>)
* Add API to check that dependent target properties form a DAG.Stephen Kelly2012-09-281-0/+44
Initially this will only be used to check for self-references, but can be extended to check for cycles when chaining properties of other targets.
