* add_custom_command: Add DEPENDS_EXPLICIT_ONLY option for NinjaAbdelmaged Khalifa2023-02-141-0/+6
| | | | | | | | | Add option `DEPENDS_EXPLICIT_ONLY` to `add_custom_command` to indicate that implicit dependencies coming from users of the output are not needed, and only consider dependencies explicitly specified in the custom command. Fixes: #17097
* cmCustomCommand: Refactor custom command-specific policy valuesKyle Edwards2023-02-061-4/+16
| | | | | | | | | | | | | | | | | Many custom commands are created by CMake itself rather than by the user. These custom commands should always have their policies set to NEW, and user-created custom commands should have their policy values set only from the state snapshot. In addition, we want to genericize the mechanism of recording a policy at the time of custom command creation. Add a CM_FOR_EACH_CUSTOM_COMMAND_POLICY macro to genericize custom command policies. Use this to define all custom command policies. Make all such policies NEW instead of WARN by default. Remove individual policy modifier methods and add a single method that records relevant values from a cmStateSnapshot. Remove the no longer needed explicit policy settings from synthesized custom commands.
* cmCustomCommand: Track main dependency explicitlyNAKAMURA Takumi2021-12-141-0/+5
| | | | | | | Store the main dependency as the first entry in the dependency list plus a boolean member indicating its existence. Note that this slightly changes existing behavior: the main dependency was previously the last entry of the dependency list.
* cmCustomCommand: Move constructor arguments to individual settersNAKAMURA Takumi2021-11-181-8/+16
| | | | | | | | Make `cmCustomCommand` have just only default constructor. Use each setter instead. This follows the builder pattern. Introduce `cc::SetOutputs(std::string output)`. This will be used later, as substitution for `cc::SetOutputs({output})`.
* add_custom_command: Target-dependent generator expression supportRaul Tambre2021-05-311-0/+5
| | | | | | | | | OUTPUT variant with a TARGET given to allow resolving target-based generator expressions wouldn't work because OUTPUT is resolved before generator targets are created, i.e. FindGeneratorTargetToUse() returns nullptr. This is a known limitation, see #21364. Implements #21336.

* 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.
* Add support to indicate UTF-8 custom command pipe output encodingJustin Goshi2020-04-131-1/+6
| | | | | | | | | | | | | | | | | Adds a flag to indicate that pipe output from a custom command should be interpreted as UTF-8 encoded. This change does not introduce a public way to set the flag, but generators that create internally-generated commands know if they are calling cmake, which uses UTF-8 pipes. MSBuild added support for interpreting output of PreBuildEvent, PreLinkEvent, PostBuildEvent, and CustomBuildStep as UTF-8. This change will appear in Visual Studio 16.6 Preview 3. It is opt-in, and you need to add the StdOutEncoding tag. MSBuild treats these as property bags so if we emit the tag for earlier versions of Visual Studio it would be safely ignored. This change emits the StdOutEncoding tag and sets it to UTF-8 whenever the custom command UTF-8 pipe flag is set. This fixes globalization issues when the output from cmake contained characters that required MSBuild to interpret as UTF-8 before displaying them.

* Revise include order using clang-format-6.0Kitware Robot2019-10-011-3/+3
| | | | | 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.
* add_custom_command: Refactor setting implicit dependsDaniel Eiband2019-09-121-8/+9
| | | | | Implicit dependencies are now passed as argument to AddCustomCommandToOutput. This is necessary to be able to delay custom command creation.
* clang-tidy: Replace typedef with usingRegina Pfeifer2019-09-041-1/+1
| | | | | | | | Automate the conversion with perl -i -0pe 's/typedef ([^;]*) ([^ ]+);/using $2 = $1;/g' then manually fix a few places.
* Support job pools in custom commands and targetsRosen Matev2019-05-141-0/+5
| | | | | | | | | | Provide a way for custom commands and targets to set the pool variable of the ninja build statement. Setting `JOB_POOL` is not compatible with `USES_TERMINAL`, which implies the `console` pool. The option is silently ignored with other generators. Closes: #18483

* 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.

* 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.

* Add an option for explicit BYPRODUCTS of custom commands (#14963)Brad King2014-11-141-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A common idiom in CMake-based build systems is to have custom commands that generate files not listed explicitly as outputs so that these files do not have to be newer than the inputs. The file modification times of such "byproducts" are updated only when their content changes. Then other build rules can depend on the byproducts explicitly so that their dependents rebuild when the content of the original byproducts really does change. This "undeclared byproduct" approach is necessary for Makefile, VS, and Xcode build tools because if a byproduct were listed as an output of a rule then the rule would always rerun when the input is newer than the byproduct but the byproduct may never be updated. Ninja solves this problem by offering a 'restat' feature to check whether an output was really modified after running a rule and tracking the fact that it is up to date separately from its timestamp. However, Ninja also stats all dependencies up front and will only restat files that are listed as outputs of rules with the 'restat' option enabled. Therefore an undeclared byproduct that does not exist at the start of the build will be considered missing and the build will fail even if other dependencies would cause the byproduct to be available before its dependents build. CMake works around this limitation by adding 'phony' build rules for custom command dependencies in the build tree that do not have any explicit specification of what produces them. This is not optimal because it prevents Ninja from reporting an error when an input to a rule really is missing. A better approach is to allow projects to explicitly specify the byproducts of their custom commands so that no phony rules are needed for them. In order to work with the non-Ninja generators, the byproducts must be known separately from the outputs. Add a new "BYPRODUCTS" option to the add_custom_command and add_custom_target commands to specify byproducts explicitly. Teach the Ninja generator to specify byproducts as outputs of the custom commands. In the case of POST_BUILD, PRE_LINK, and PRE_BUILD events on targets that link, the byproducts must be specified as outputs of the link rule that runs the commands. Activate 'restat' for such rules so that Ninja knows it needs to check the byproducts, but not for link rules that have no byproducts.
* Add USES_TERMINAL option for custom commandsPeter Collingbourne2014-11-141-0/+6
| | | | | | Teach the add_custom_command and add_custom_target commands a new USES_TERMINAL option. Use it to tell the generator to give the command direct access to the terminal if possible.
* genex: remove the need for backtracesBen Boeckel2014-06-051-2/+2
| | | | | Rather than making dummy backtraces and passing them around, just make backtraces optional.
* cmCustomCommand: Return std::string from GetWorkingDirectoryBrad King2014-03-121-3/+4

* 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.

* add_custom_command: Manage backtrace memory correctly (#14299)Brad King2013-07-171-0/+1

* Record backtrace in cmCustomCommandBrad King2010-12-151-1/+10
| | | | | This will be used to report custom command errors to the user with a backtrace pointing at the add_custom_command or add_custom_target call.
* 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.
* ENH: Remove SKIP_RULE_DEPENDS option from add_custom_command()Brad King2008-06-021-5/+0
| | | | | | | | - Option was recently added but never released. - Custom commands no longer depend on build.make so we do not need the option. - Rule hashes now take care of rebuilding when rules change so the dependency is not needed.
* ENH: Add SKIP_RULE_DEPENDS option for add_custom_command()Brad King2008-05-141-0/+5
| | | | | | - Allows make rules to be created with no dependencies. - Such rules will not re-run even if the commands themselves change. - Useful to create rules that run only if the output is missing.

* ENH: Added support for multiple outputs generated by a single custom ↵Brad King2006-04-111-3/+3
| | | | command. For Visual Studio generators the native tool provides support. For Xcode and Makefile generators a simple trick is used. The first output is considered primary and has the build rule attached. Other outputs simply depend on the first output with no build rule. During cmake_check_build_system CMake detects when a secondary output is missing and removes the primary output to make sure all outputs are regenerated. This approach always builds the custom command at the right time and only once even during parallel builds.
