* Revise include order using clang-format-6.0Kitware Robot2019-10-011-1/+2
| | | | | 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 Chevrier2019-09-201-1/+2
| | | | | | | | | | | | | | 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
* Refactor: Use cmStrCat to construct error stringsAsit Dhal2019-09-181-69/+42
| | | | | Replace string construction using std::stringstream with cmStrCat and cmWrap.

| | | | | | 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.

| * Source sweep: Replace std::ostringstream when used with a single appendSebastian Holtermann2019-08-231-3/+3
| | | | | | | | | | | | | | This replaces `std::ostringstream`, when it is written to only once. If the single written argument was numeric, `std::to_string` is used instead. Otherwise, the single written argument is used directly instead of the `std::ostringstream::str()` invocation.

* | Source sweep: Use cmStrCat for string concatenationSebastian Holtermann2019-08-221-8/+6
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is generated by a python script that uses regular expressions to search for string concatenation patterns of the kind ``` std::string str = <ARG0>; str += <ARG1>; str += <ARG2>; ... ``` and replaces them with a single `cmStrCat` call ``` std::string str = cmStrCat(<ARG0>, <ARG1>, <ARG2>, ...); ``` If any `<ARGX>` is itself a concatenated string of the kind ``` a + b + c + ...; ``` then `<ARGX>` is split into multiple arguments for the `cmStrCat` call. If there's a sequence of literals in the `<ARGX>`, then all literals in the sequence are concatenated and merged into a single literal argument for the `cmStrCat` call. Single character strings are converted to single char arguments for the `cmStrCat` call. `std::to_string(...)` wrappings are removed from `cmStrCat` arguments, because it supports numeric types as well as string types. `arg.substr(x)` arguments to `cmStrCat` are replaced with `cm::string_view(arg).substr(x)`

* | cmStringAlgorithms: cmIsSpace, cmTrimWhitespace, cmEscapeQuotes, cmTokenizeSebastian Holtermann2019-08-051-1/+1
|/ | | | | | | | | | This adds the following functions to `cmStringAlgorithms`: - `cmIsSpace` - `cmTrimWhitespace` (moved from `cmSystemTools::TrimWhitespace`) - `cmEscapeQuotes` (moved from `cmSystemTools::EscapeQuotes`) - `cmTokenize` (moved from `cmSystemTools::tokenize` and adapted to accept `cm::string_view`)
* cmStringAlgorithms: Move string functions to the new cmStringAlgorithms.hSebastian Holtermann2019-07-291-0/+1
| | | | | This adds the `cmStringAlgorithms.h` header and moves all string functions from `cmAlgorithms.h` to `cmStringAlgorithms.h`.
* cmMakefile: Let AddDefinition accept a value as cm::string_viewSebastian Holtermann2019-07-241-20/+18
| | | | | | | | | | | | | | | | This changes `cmMakefile::AddDefinition` to take a `cm::string_view` as value argument instead of a `const char *`. Benefits are: - `std::string` can be passed to `cmMakefile::AddDefinition` directly without the `c_str()` plus string length recomputation fallback. - Lengths of literals passed to `cmMakefile::AddDefinition` can be computed at compile time. In various sources uses of `cmMakefile::AddDefinition` are adapted to avoid `std::string::c_str` calls and the `std::string` is passed directly. Uses of `cmMakefile::AddDefinition`, where a `nullptr` `const char*` might be passed to `cmMakefile::AddDefinition` are extended with `nullptr` checks.

* IWYU: Fix handling of <memory> standard headerBrad King2019-07-101-0/+2
| | | | | | | | An old workaround for `std::allocator_traits<>::value_type` lints from IWYU on `std::vector<>` usage breaks IWYU's handling of `<memory>`. Convert the workaround to use the same approach we already use for a workaround of `std::__decay_and_strip<>::::__type` lints. Then update the `<memory>` inclusions to follow the now-correct IWYU lints.

* | cmListCommand: Avoid std::function move constructor on aarch64Brad King2019-01-241-0/+5
|/ | | | | | | | Since commit 5a0784ddea (clang-tidy: Pass by value, 2019-01-21), some of the `RunCMake.{list,PositionIndependentCode}` cases have crashed on an aarch64 build with GCC 6. Avoiding use of the `std::function` move constructor avoids the crash. Use a strict preprocessor condition to use this workaround only where needed.

* 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.
