* cmake_minimum_required: Optionally set policies with version rangeBrad King2018-03-211-1/+18
| | | | | | | | Teach `cmake_minimum_required` and `cmake_policy(VERSION)` to support a version range of the form `<min>[...<max>]`. Define this to mean that version `<min>` is required, but known policies up to those introduced by `<max>` will be set to `NEW`. This will allow projects to easily specify a range of versions for which they have been updated.

* cmListFileCache: Remove cmState header includeStephen Kelly2016-10-191-0/+1
| | | | | Include it in dependents which have previously relied on it transitively.
* cmState: Move CacheEntryType enum to separate namespaceStephen Kelly2016-10-191-1/+1
| | | | Port dependent code to the change.
* 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copyright/license notice headers that spell out copyright holder names and years are hard to maintain and often out-of-date or plain wrong.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 Robot2016-05-161-79/+51
| | | | | | | | | | | | | 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 King2016-05-091-3/+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.
* cmMakefile: Remove CMP0001 handling to callers.Stephen Kelly2015-07-251-0/+16

* Port to static cmPolicies API.Stephen Kelly2015-05-041-2/+2

* Port all cmOStringStream to std::ostringstream.Stephen Kelly2015-01-111-4/+4
| | | | All compilers hosting CMake support the std class.
* Remove some c_str() calls.Stephen Kelly2014-03-111-6/+6
| | | | | | 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.
* 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: Create policy scope barriersBrad King2009-01-221-10/+4
| | | | | This creates a barrier mechanism to prevent user code from using cmake_policy(POP) to pop a scope it didn't push with cmake_policy(PUSH).
* ENH: Add cmake_policy(GET) command modeBrad King2008-08-181-0/+61
| | | | | | | It is likely that projects or CMake modules in the future will need to check the value of a policy setting. For example, if we add a policy that affects the results of FindXYZ.cmake modules, the module code will need to be able to check the policy.
* ENH: Cleanup policy version interface presented to user.Brad King2008-03-241-8/+1
| | | | | | | - In cmake_minimum_required do not set policy version if current CMake is too old - In cmPolicies::ApplyPolicyVersion report error if version is too new or cannot be parsed
* ENH: Improve cmake_policy command signatureBrad King2008-03-051-30/+101
| | | | | - Replace NEW and OLD modes with a SET mode for clarity - Enforce VERSION argument validity (major.minor[.patch])
* ENH: just getting somethng checked in, still work to doKen Martin2008-02-291-0/+58
