* 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.

* cmAlgorithms: Fix -Wnon-c-typedef-for-linkage warningsRaul Tambre2020-03-091-2/+2
| | | | | | | | | In commit bf1e73305a (cmAlgorithms: Refactor cmRemoveDuplicates, 2019-03-03, v3.15.0-rc1~414^2) we added `union X = struct {}`. C++ had a rule change whereby only C-compatible unnamed typedefs are allowed. Clang 11 warns about this by default. See https://reviews.llvm.org/D74103. The aliases don't seem to be necessary, so simply define as structs.

* Revise include order using clang-format-6.0Kitware Robot2019-10-011-2/+4
| | | | | 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.
* cmstd: Modernize CMake system headersMarc Chevrier2019-09-201-77/+0
| | | | | | | | | | | | | | Provide a standardized way to handle the C++ "standard" headers customized to be used with current CMake C++ standard constraints. Offer under directory `cm` headers which can be used as direct replacements of the standard ones. For example: #include <cm/string_view> can be used safely for CMake development in place of the `<string_view>` standard header. Fixes: #19491
* clang-tidy: modernize-use-autoRegina Pfeifer2019-09-101-3/+3
| | | | | | Set the MinTypeNameLength option to an impossibly high value in order to limit the diagnostics to iterators. Leave new expressions and cast expressions for later.

* cmStringAlgorithms: Move string functions to the new cmStringAlgorithms.hSebastian Holtermann2019-07-291-126/+0
| | | | | This adds the `cmStringAlgorithms.h` header and moves all string functions from `cmAlgorithms.h` to `cmStringAlgorithms.h`.

* cmAlgorithms: Make cmHasPrefix and cmHasSuffix cm::string_view basedSebastian Holtermann2019-07-221-9/+28
| | | | | | | | | Make `cmHasPrefix`, `cmHasSuffix` and `cmStripSuffixIfExists` accept arguments as `cm::string_view` instead of `const std::string&`. This lets them accept literal strings without having to allocate a temporary `std::string`. Add variants of `cmHasPrefix`, `cmHasSuffix` and `cmStripSuffixIfExists` that accept a single character as second argument.

* cmAlgorithms: Add cmAppend functionSebastian Holtermann2019-05-231-0/+12
| | | | | The new `cmAppend` function simplifies appending ranges of values to a `std::vector`.
* cmAlgorithms: Refactor cmRemoveDuplicatesArtur Ryt2019-03-061-18/+36
| | | | | | | | Use an iterator-based implementation with range-based one simply deferring to it. Also optimize a little by storing iterators to unique values to prevent creating value copies.

| | | | | | | | | | | std::{begin,end} are part of C++11, std::{cbegin,cend} are part of C++14 and an standard compliant implementation has been introduced within the 'cm' namespace: cm::{cbegin,cend}. std::size is only part of C++17, hence exposing a compliant implementation within namespace cm (cm::size). where possible, the standard implementations are reused.

* 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.

* Remove temporary allocations when calling cmHasLiteral{Suf,Pre}fix.Milian Wolff2016-01-201-2/+2
| | | | | | | | | When the first argument passed is a std::string, we need to take it by const&, otherwise we copy the string and trigger a temporary allocation. This patch removes a few 10k temporary allocations when running the CMake daemon on the KDevelop build dir. This hotspot was found with heaptrack.
