* Code style: add missed explicit 'this->'Oleksandr Koval2021-01-051-63/+71
| | | | | CMake uses explicit 'this->' style. Using custom clang-tidy check we can detect and fix places where 'this->' was missed.
* 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.

* Revise include order using clang-format-6.0Kitware Robot2019-10-011-3/+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 Chevrier2019-09-201-1/+1
| | | | | | | | | | | | | | 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: 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.

* IWYU: Add missing cstddef includes for size_t and nullptr_tBrad King2019-09-031-0/+1
| | | | The IWYU tool we use for CI now diagnoses these.
* IWYU: Update CMake code for IWYU built with Clang 6Brad King2019-01-151-0/+1
| | | | | IWYU now correctly requires `<utility>` for `std::move`. It also requires a container header when used via a range-based for loop.

* String: Add str_if_stable() as a const alternative to str()Brad King2018-12-121-0/+14
| | | | | | | | | | | | | | | | The `str()` method must be non-const because it may need to internally mutate the representation of the string in order to have an owned `std::string` instance holding the exact string (not a superstring). This is inconvenient in contexts where we can ensure that no mutation is needed to get a `std::string const&`. Add a `str_if_stable() const` method that returns `std::string const*` so we can return `nullptr` if if mutation would be necessary to get a `std::string const&`. Add supporting `is_stable() const` and `stabilize()` methods to check and enforce stable availability of `std::string const&`. These can be used to create `String const` instances from which we can still get a `std::string const&` via `*str_if_stable()` by maintaining the stability invariant at runtime.
* String: Add support for a ""_s string literal syntaxBrad King2018-12-121-1/+14
| | | | | Create a `static_string_view` type that binds only to the static storage of string literals. Teach `cm::String` to borrow from these implicitly.
* String: Add 'borrow' member to construct borrowing instancesBrad King2018-12-121-0/+4
| | | | | | This will allow creation of `cm::String` instances that borrow from non-owned storage. It is the caller's responsibility to ensure that no copy of the instance outlives the borrowed buffer.
* String: Add support for concatenation by operator+Brad King2018-12-121-0/+101
| | | | | | Use expression templates to collect the entire expression and pre-allocate a string with the final length before concatenating the pieces.
* String: Add a custom string typeBrad King2018-12-121-0/+683
Create a `cm::String` type that holds a view of a string buffer and optionally shares ownership of the buffer. Instances can either borrow longer-lived storage (e.g. static storage of string literals) or internally own a `std::string` instance. In the latter case, share ownership with copies and substrings. Allocate a new internal string only on operations that require mutation. This will allow us to recover string sharing semantics that we used to get from C++98 std::string copy-on-write implementations. Such implementations are not allowed by C++11 so code our own in a custom string type instead.
