* Fix crash with --trace-expand --warn-uninitialized togetherR2RT2018-04-091-4/+5
| | | | | | | | Some code paths in `ExpandVariablesInString{New,Old}` were not checking the `filename` parameter for a null pointer, but this can happen when using the above flags together. Add the checks and a test case. Fixes: #17896
* cmCommandArgumentParser: remove the variable tokens from the classRolf Eike Beer2017-10-251-11/+4
| | | | Make them local constants in the lexer file.

* 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copyright/license notice headers that spell out copyright holder names and years are hard to maintain and often out-of-date or plain wrong.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.

* Revise C++ coding style using clang-formatKitware Robot2016-05-161-154/+111
| | | | | | | | | | | | | 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.
* Source: Sort includes the way clang-format wouldBrad King2016-05-031-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | Re-apply the approach from commit e1c77472 (Format include directive blocks and ordering with clang-format, 2016-04-29) but this time be more careful about exclusion of parser generator sources: $ git ls-files -z -- \ '*.c' '*.cc' '*.cpp' '*.cxx' '*.h' '*.hh' '*.hpp' '*.hxx' | egrep -z -v '^Source/cmCommandArgumentLexer\.' | egrep -z -v '^Source/cmCommandArgumentParser\.' | egrep -z -v '^Source/cmDependsJavaLexer\.' | egrep -z -v '^Source/cmDependsJavaParser\.' | egrep -z -v '^Source/cmExprLexer\.' | egrep -z -v '^Source/cmExprParser\.' | egrep -z -v '^Source/cmFortranLexer\.' | egrep -z -v '^Source/cmFortranParser\.' | egrep -z -v '^Source/cmListFileLexer\.' | egrep -z -v '^Source/cm_sha2' | egrep -z -v '^Source/(kwsys|CursesDialog/form)/' | egrep -z -v '^Utilities/(KW|cm).*/' | egrep -z -v '^Tests/Module/GenerateExportHeader' | egrep -z -v '^Tests/RunCMake/CommandLine/cmake_depends/test_UTF-16LE.h' | xargs -0 clang-format -i Also drop use of custom sorting for `sys/types.h`.
* Add call stack to unused/uninitialized variable warningsBrad King2016-04-151-8/+1
| | | | | | | | In commit v2.8.4~32^2~14 (Use cmake::IssueMessage for warnings, 2010-12-07) these warnings became formatted. It is more informative to give the full call stack with such warnings. Also it is easier to implement warnings with a full call stack because we do not have to construct a custom backtrace with only the top.

* cmake: Add IssueMessage overload taking a single cmListFileContext.Stephen Kelly2015-05-211-4/+5
| | | | Port appropriate clients to use it.
* cmListFileBacktrace: Hide the context-stack implementation detail.Stephen Kelly2015-05-181-1/+1
| | | | | | The backtrace will soon not be implemented in terms of a stack of cmListFileContext objects. Keep the cmListFileContext in the API for convenience for now.
* Port to cmState.Stephen Kelly2015-04-131-1/+2

* cmCacheManager: Rename GetCacheValue to GetInitializedCacheValue.Stephen Kelly2015-04-071-1/+2
| | | | | Being initialized is a requirement for this method to return something, and is what differentiates it from using GetIterator with it.GetValue.
* Revert topic 'refactor-cache-api'Brad King2015-04-071-2/+1
| | | | | | This topic was never tested without some follow-up commits. The GetCacheEntryValue API returns a pointer to memory freed on return. It will have to be revised along with the rest of the original topic.
* cmCacheManager: Rename GetCacheValue to GetInitializedCacheValue.Stephen Kelly2015-04-061-1/+2

* Port all cmOStringStream to std::ostringstream.Stephen Kelly2015-01-111-5/+5
| | | | All compilers hosting CMake support the std class.
* backtrace: Convert to local paths in IssueMessageBen Boeckel2014-06-051-1/+1
| | | | | This is the only place we care show the FilePath to the user, so defer the expensive relative path calculation until here.
* Remove c_str calls when using stream APIs.Stephen Kelly2014-03-111-1/+1
| | | | | Use an ad-hoc clang tool for matching the calls which should be ported.
* 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.
* stringapi: Use strings for AddString methodsBen Boeckel2014-03-081-6/+6
| | | | It gets turned into a string anyways, so pass them in.
* Include cmMakefile.h before cm*Lexer.h to get stdint.h firstBrad King2013-08-071-2/+2
| | | | | | | Some generated cm*Lexer.h headers define preprocessor macros normally provided by <stdint.h>. The latter is included indrectly by cmMakefile.h since commit 2268c41a (Optimize custom command full-path dependency lookup, 2013-08-06). Adjust the order to avoid redefinition warnings.
* Remove trailing whitespace from most CMake and C/C++ codeKitware Robot2012-08-131-5/+5
| | | | | | | | | | | | | | | | | Our Git commit hooks disallow modification or addition of lines with trailing whitespace. Wipe out all remnants of trailing whitespace everywhere except third-party code. Run the following shell code: git ls-files -z -- \ bootstrap doxygen.config '*.readme' \ '*.c' '*.cmake' '*.cpp' '*.cxx' \ '*.el' '*.f' '*.f90' '*.h' '*.in' '*.in.l' '*.java' \ '*.mm' '*.pike' '*.py' '*.txt' '*.vim' | egrep -z -v '^(Utilities/cm|Source/(kwsys|CursesDialog/form)/)' | egrep -z -v '^(Modules/CPack\..*\.in)' | xargs -0 sed -i 's/ \+$//'

* 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.
* BUG: Fix CMAKE_CURRENT_LIST_FILE in macrosBrad King2009-03-251-5/+1
| | | | | | | | | | | | | | | | | | | | | The value of CMAKE_CURRENT_LIST_FILE is supposed to be the list file currently being executed. Before macros were introduced this was always the context of the argument referencing the variable. Our original implementation of macros replaced the context of command arguments inside the macro with that of the arguments of the calling context. This worked recursively, but only worked when macros had at least one argument. Furthermore, it caused parsing errors of the arguments to report the wrong location (calling context instead of line with error). The commit "Improve context for errors in macros" fixed the latter bug by keeping the lexical context of command arguments in macros. It broke evaluation of CMAKE_CURRENT_LIST_FILE because the calling context was no longer preserved in the argument referencing the variable. However, since our list file processing now maintains the proper value of CMAKE_CURRENT_LIST_FILE with dynamic scope we no longer need the context of the argument and can just evaluate the variable normally.
* ENH: Create $CACHE{VAR} syntaxBrad King2008-09-251-1/+16
| | | | | This syntax allows reading of cache entries even when variables of the same name have been defined in the local scope. See issue #7715.
* ENH: Improve argument parsing error messagesBrad King2008-09-241-7/+18
| | | | | | | | | | | | | | Previously error messages produced by parsing of command argument variable references, such as bad $KEY{VAR} syntax or a bad escape sequence, did not provide good context information. Errors parsing arguments inside macro invocations gave no context at all. Furthermore, some errors such as a missing close curly "${VAR" would be reported but build files would still be generated. These changes teach CMake to report errors with good context information for all command argument parsing problems. Policy CMP0010 is introduced so that existing projects that built despite such errors will continue to work.
* BUG: Fixed @ONLY configuration to not try to parse ${} syntax at all. This ↵Brad King2007-06-061-28/+2
