* cmstd: Modernize CMake system headersMarc Chevrier2019-09-201-2/+3
| | | | | | | | | | | | | | 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 Pfeifer2019-09-101-2/+1
| | | | | | 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/+1
| | | | | | | 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 Holtermann2019-08-221-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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)`

| | | | | 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 Holtermann2019-07-241-5/+5
| | | | | | | | | | | | | | | | 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.

* cmCommand: deprecate functions GetMakefile and SetErrorDaniel Pfeifer2019-07-211-1/+1
| | | | | | | | | Replace the members for the Makefile and the Error with a cmExecutionStatus. Re-implement GetMakefile and SetError based on that. Both functions should be called directly on the cmExecutionStatus that is passed to InitialPass. This will help us make all Commands immutable and remove the need for cloning.

* clang-tidy: Use `= default`Regina Pfeifer2019-01-251-2/+2
| | | | | | Suppress some cases in `Source/cmGeneratorExpressionNode.cxx` and `Source/cmUVHandlePtr.h` where a few older compilers require a user-defined default constructor (with `{}`).
* Revise implementation of case-insensitive command namesFlorian Jacomme2018-05-221-4/+3
| | | | | | | | | | | | | | | | | | | | Store both the as-written and lower-case command names and use the latter to avoid case-insensitive string comparisons. With this I obtain 2-6% speed increase (on Windows) for the configure step with no significant changes in memory usage. A case-insensitive comparison is a lot slower than just calling `==` because the operator will use things like memcmp, so prefer the latter. The `cmSystemTools::LowerCase` function allocates a new string each time it is called, so before this change we were allocating in: * cmMakefile::Configure two times for each function (to look for `cmake_minimum_required` and `project`) * cmMakefile::ExecuteCommand twice by function by calling cmState::GetCommand and copying the name Now we are only allocating once by function instead of four.
* Use C++11 override instead of CM_OVERRIDEBrad King2017-09-151-4/+4
| | | | | | | | We now require C++11 support including `override`. Drop use of the old compatibility macro. Convert references as follows: git grep -l CM_OVERRIDE -- '*.h' '*.hxx' '*.cxx' | xargs sed -i 's/CM_OVERRIDE/override/g'
* Meta: modernize old-fashioned loops to range-based `for`.Pavel Solodovnikov2017-09-121-2/+2
| | | | | | Changes done via `clang-tidy` with some manual fine-tuning for the variable naming and `auto` type deduction where appropriate.

* 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.

* cmMakefile: Restore nested error logic use of cmExecutionStatusBrad King2016-09-061-3/+3
| | | | | | | | | | | | | | Since commit 14a8d61f (cmMakefile: Port nested error logic away from cmExecutionStatus) we fail to continue processing function and macro bodies after non-fatal errors. A non-fatal error should not stop foreach loops, macro bodies, nested bodies, or the outer script. Add a test covering these cases, and revert the change to fix them. Also revert commit 2af853de (cmMakefile: Simplify IssueMessage implementation) because the assertion it added (which was removed by the above commit and is restored by reverting it) is incorrect. We do have code paths that call cmMakefile::IssueMessage with an empty execution stack, such as in CheckForUnusedVariables's LogUnused call.

| | | | | | | | | The cmListFileArgument currently stores a FilePath for use in this method.

Set the context filename when expanding the arguments of macros and functions using the filename recorded when defining the prototype.

| | | | | | | | | | | | | | | | | | | | | | | | The lexical scope counting added by commit v3.2.0-rc1~332^2~1 (Track nested loop levels in CMake language with a stack of counters, 2014-11-18) forgot to account for scopes popped by error messages about unclosed scopes. Teach the error handler to pop the lexical scope it reports as unclosed. Re-order the lexical scope RAII object to be inside the variable scope RAII object scope so that the lexical scope is fully closed before we check assertions about variable scopes. Extend the RunCMake.Syntax test with a case covering this.
