* Reduce raw string pointers usage.Pavel Solodovnikov2018-01-311-1/+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.
* Make use of std::chrono throughout every componentWouter Klouwen2018-01-231-2/+2
| | | | | | | | This commit continues the changes made in CTest to support std::chrono by applying it throughout every component where a duration was used. No functional change intended.

* 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copyright/license notice headers that spell out copyright holder names and years are hard to maintain and often out-of-date or plain wrong.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 Robot2016-05-161-173/+116
| | | | | | | | | | | | | 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.
* 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.
* Source: Stabilize include orderBrad King2016-04-291-0/+1
| | | | | 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.
* try_compile: Add option to control type of targetBrad King2016-02-191-1/+1
| | | | | | | Create a `CMAKE_TRY_COMPILE_TARGET_TYPE` option to specify use of `add_library(... STATIC ...)` for the generated test project. This will be useful for cross-compiling toolchains that cannot link a binary without custom flags or scripts.
* cmMakefile: Rename method to something more appropriate.Stephen Kelly2015-05-191-1/+1
| | | | Allow the name to be used for something more-suitable.
* cmSystemTools: Teach RunSingleCommand to separate stdout and stderrBrad King2015-04-201-1/+1
| | | | | | | Extend the RunSingleCommand signature to capture stdout and stderr separately. Allow both to be captured to the same std::string to preserve existing behavior. Update all call sites to do this so that this refactoring does not introduce functional changes.

* | try_run: Use CMAKE_CROSSCOMPILING_EMULATOR.Matt McCormick2015-04-081-2/+24
|/ | | | | | | If the CMAKE_CROSSCOMPILING_EMULATOR variable is defined, and CMAKE_CROSSCOMPILING is TRUE, then use CMAKE_CROSSCOMPILING_EMULATOR to run the try_run executables. This prevents the need to populate TryRunResults.cmake when cross compiling.

* 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.
* Generate modern-style cmake code.Stephen Kelly2013-08-221-2/+2
| | | | | | | | | | | The commits 9db31162 (Remove CMake-language block-end command arguments, 2012-08-13) and 77543bde (Convert CMake-language commands to lower case, 2012-08-13) changed most cmake code to use lowercase commands and no parameters in termination commands. However, those changes excluded cmake code generated in c++ by cmake. Make a similar style change to code generated by cmake.

| | | | | | | | | | | | | | | creates two cache variables, one for the RUN_RESULT, one for the RUN_OUTPUT (if required), which can be set or preset by the user. It has now also two new arguments: RUN_OUTPUT_VARIABLE and COMPILE_OUTPUT_VARIABLE (the old OUTPUT_VARIABLE merges both), so if only COMPILE_OUTPUT_VARIABLE is used the run time output of the TRY_RUN is unused and the user doesn't have to care about the output when crosscompiling. This is now used in FindThreads.cmake, CheckC/CXXSourceRuns.cmake and TestBigEndian.cmake, which used the output only for the logfile (compile output is still there). Test/TryCompile/ now also tests the behaviour of OUTPUT_VARIABLE, RUN_OUTPUT_VARIABLE and COMPILE_OUTPUT_VARIABLE. Alex
