* cmMakefile: Make GetSafeDefinition return std::string const&Vitaly Stakhovsky2018-09-181-1/+1

* cmDepends: Remove attempt to change directory that always failsCraig Scott2018-03-081-6/+1
| | | | | | | Nothing ever set `CompileDirectory` except `SetDirectory()`, but nothing ever called that function. Therefore, `CompileDirectory` was always empty for the attempt to change directory in `Check()`, which therefore would always fail. Nothing was checking the result and the code was always going to have no effect.
* Meta: modernize old-fashioned loops to range-based `for`.Pavel Solodovnikov2017-09-121-4/+2
| | | | | | Changes done via `clang-tidy` with some manual fine-tuning for the variable naming and `auto` type deduction where appropriate.
* clang-format: format all code as Cpp11Daniel Pfeifer2017-08-301-2/+2

* Use quotes for non-system includesDaniel Pfeifer2017-04-111-1/+1
| | | | | | | | | | | | | Automate with: git grep -l '#include <cm_' -- Source \ | xargs sed -i 's/#include <\(cm_.*\)>/#include "\1"/g' git grep -l '#include <cmsys/' -- Source \ | xargs sed -i 's/#include <\(cmsys\/.*\)>/#include "\1"/g' git grep -l '#include <cm[A-Z]' -- Source \ | xargs sed -i 's/#include <\(cm[A-Z].*\)>/#include "\1"/g'
* cmWorkingDirectory: use the new classBen Boeckel2017-03-061-12/+2
| | | | | | These functions just need to change the directory for a block of code and then go back to the caller's expected location. Use cmWorkingDirectory to ensure that all return paths are handled.
* 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copyright/license notice headers that spell out copyright holder names and years are hard to maintain and often out-of-date or plain wrong.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 Robot2016-05-161-113/+84
| | | | | | | | | | | | | 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 King2016-05-091-9/+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.
* Format include directive blocks and ordering with clang-formatBrad King2016-04-291-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Port all cmOStringStream to std::ostringstream.Stephen Kelly2015-01-111-4/+4
| | | | All compilers hosting CMake support the std class.
* strings: Remove redundant calls to std::string::c_str()Nils Gladitz2014-10-151-2/+2
| | | | | Replacements were detected and performed by the clang tool remove-cstr-calls on a linux build.
* cmDepends: Refactor object file path conversionBrad King2014-07-221-6/+1
| | | | | | | | Delay conversion of the path to object files (on the left-hand side of dependencies) until just before they are written. Also do not convert the format of paths written to the 'depend.internal' file. This is consistent with the way the right-hand side of dependencies are already handled.
* cmLocalGenerator: Rename 'MAKEFILE' to 'MAKERULE'Brad King2014-07-221-1/+1
| | | | | Rename the internal enumeration value for converting paths destined for use in Makefile rule syntax.
* Remove some c_str() calls.Stephen Kelly2014-03-111-4/+4
| | | | | | 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.

* Use cmsys::[io]fstream instead of cmsys_ios::[io]fstream.Clinton Stimpson2014-01-071-1/+2
| | | | | Also use SystemTools::Fopen() instead of fopen(). This is to eventually support utf-8 filenames.
* cmDepends: No dependency-vector erasure in CheckDependenciesMichael Wild2012-11-061-2/+4
| | | | | | | | Some dependency-generators (such as cmDependsFortran) generate multiple entries per depender, so erasing the dependency vector for each depender found loses earlier dependencies. Signed-off-by: Michael Wild <themiwi@users.sourceforge.net>
* cmDepends: allow multiple dependees per dependerAlex Neundorf2012-11-061-3/+10
| | | | | | | | | | | | | | | | | | | | | This patch is heavily inspired by Michael Wild. The interfaces cmDepends::Write and cmDepends::WriteDependencies where extended to allow multiple dependees (sources) per depender (object). cmDepends::Write first collect all dependencies into a std::set before passing it to cmDepends::WriteDependencies. cmDependsC::WriteDependencies also first collects all explicit and implicit dependencies into a std::set and only then writes depend.{internal,make}. The implementation of cmDependsFortran simply loops over all sources and proceeds as before, whereas the cmDependsJava implementation is as trivial as before. This is for preventing exponential growth of depend.{internal,make} in the next commit which fixes dependency-vector erasure in cmDepends::CheckDependencies.

* fix #13474: also rescan dependencies if the depender does not existAlex Neundorf2012-08-171-17/+46
| | | | | | | | If the depender (e.g. foo.o) does not exist, also rescan dependencies if one of the dependees (e.g. foo.cxx) is older than the already existing depend.internal file, since this means it can be out of date. Alex
* 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/ \+$//'

| | | | Avoid assignment inside the if.
* Fix compiler error reported on older Borland dashboard.David Cole2012-02-221-2/+3
| | | | Declare variable only once at a scope appropriate for both uses.
* Extract and use the INCLUDE_DIRECTORIES target properties.Stephen Kelly2012-02-221-1/+13
| | | | | | | | | Eliminate callers of cmMakefile::GetIncludeDirectories. All callers of GetIncludeDirectories should go through the local generator object. Only the local generator calls cmTarget::GetIncludeDirectories directly.
* Remove call to SystemTools::GetMaximumFilePathLengthBrad King2010-12-161-1/+1
| | | | | | The KWSys SystemTools::GetMaximumFilePathLength method is poorly conceived and should not be used. The cmDepends code honors its own MaxPath buffer size. Just hard-code it.
* 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.
* Major optimization of C/C++ dependency scanning.Alexander Neundorf2009-09-231-3/+23
| | | | | | | | | | | | | | Now only the dependencies for the file where the dependencies actually may have changed are rescanned, before that this was done for all source files even if only one source file had changed. This reduces e.g. on my machine the time for scanning the dependencies of kdelibs/khtml/ when only one file (khtml_global.cpp) has changed from around 7.5 seconds to 1.2 seconds. The tests succeed, it does what I expected it to do on kdelibs, and Brad also reviewed the patch, so I think it should be ok. Alex
* Minor optimization in dependency checking.Alexander Neundorf2009-09-191-2/+12
| | | | | | | | | | | | When reading the depend.internal file, check only once for every depender whether it exists, instead of repeatedly in a loop for each dependee. Within that function it can only change of the depender is removed. This is taken care of. This reduces the number of access() calls in kdelibs/khtml from 180000 to 90000 (i.e. 50%), and reduces the time for that (without the actual scanning) from 0.3 s to 0.21 s on my system. Alex

This allows the rules written into the depend.make files to use the same relative path conversion as those written into the build.make files. Several previous changes added more and more information for use by the dependency scanner and it was converging to having the full local generator anyway.
