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copyright/license notice headers that spell out copyright holder names and years are hard to maintain and often out-of-date or plain wrong.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

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.
* Remove `//------...` horizontal separator commentsBrad King2016-05-091-13/+0
| | | | | | | | | | | | | | | | | | | | | | | | Modern editors provide plenty of ways to visually separate functions. Drop the explicit comments that previously served this purpose. Use the following command to automate the change: $ git ls-files -z -- \ "*.c" "*.cc" "*.cpp" "*.cxx" "*.h" "*.hh" "*.hpp" "*.hxx" | egrep -z -v "^Source/cmCommandArgumentLexer\." | egrep -z -v "^Source/cmCommandArgumentParser(\.y|\.cxx|Tokens\.h)" | egrep -z -v "^Source/cmDependsJavaLexer\." | egrep -z -v "^Source/cmDependsJavaParser(\.y|\.cxx|Tokens\.h)" | egrep -z -v "^Source/cmExprLexer\." | egrep -z -v "^Source/cmExprParser(\.y|\.cxx|Tokens\.h)" | egrep -z -v "^Source/cmFortranLexer\." | egrep -z -v "^Source/cmFortranParser(\.y|\.cxx|Tokens\.h)" | egrep -z -v "^Source/cmListFileLexer\." | egrep -z -v "^Source/cm_sha2" | egrep -z -v "^Source/(kwsys|CursesDialog/form)/" | egrep -z -v "^Utilities/(KW|cm).*/" | xargs -0 sed -i '/^\(\/\/---*\|\/\*---*\*\/\)$/ {d;}' This avoids modifying third-party sources and generated sources.
* Isolate formatted streaming blocks with clang-format off/onBrad King2016-05-061-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The clang-format tool can do a good job formatting most code, but well-organized streaming blocks are best left manually formatted. Find blocks of the form os << "...\n" "...\n" ; using the command $ git ls-files -z -- Source | egrep -v -z '^Source/kwsys/' | xargs -0 pcregrep -M --color=always -B 1 -A 1 -n \ '<<[^\n]*\n(^ *("[^\n]*("|<<|;)$|;)\n){2,}' Find blocks of the form os << "...\n" << "...\n" << "...\n"; using the command $ git ls-files -z -- Source | egrep -v -z '^Source/kwsys/' | xargs -0 pcregrep -M --color=always -B 1 -A 1 -n \ '<<[^\n]*\n(^ *<<[^\n]*(\\n"|<<|;)$\n){2,}' Surround such blocks with the pair /* clang-format off */ ... /* clang-format on */ in order to protect them from update by clang-format. Use the C-style `/*...*/` comments instead of C++-style `//...` comments in order to prevent them from ever being swallowed by re-formatting of surrounding comments.
* Format include directive blocks and ordering with clang-formatBrad King2016-04-291-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sort include directives within each block (separated by a blank line) in lexicographic order (except to prioritize `sys/types.h` first). First run `clang-format` with the config file: --- SortIncludes: false ... Commit the result temporarily. Then run `clang-format` again with: --- SortIncludes: true IncludeCategories: - Regex: 'sys/types.h' Priority: -1 ... Commit the result temporarily. Start a new branch and cherry-pick the second commit. Manually resolve conflicts to preserve indentation of re-ordered includes. This cleans up the include ordering without changing any other style. Use the following command to run `clang-format`: $ git ls-files -z -- \ '*.c' '*.cc' '*.cpp' '*.cxx' '*.h' '*.hh' '*.hpp' '*.hxx' | egrep -z -v '(Lexer|Parser|ParserHelper)\.' | 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 This selects source files that do not come from a third-party.

| * cmCacheManager: Avoid cache entry self-assignmentBrad King2014-05-271-5/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Since commit bef93dc5 (Couple of changes: cache variables now have a map of properties, 2002-09-11) the cmCacheManager::AddCacheDefinition method accesses its map entry by reference. However, the commit left the original entry assignment at the end of the method. With Apple Clang 5.1 and libc++ this self-assignment destroys the cache entry property map. Drop the self assignment. Also drop the condition around the call to UnwatchUnusedCli since it was a self-comparison that must always have been true.
* | Remove c_str calls when using stream APIs.Stephen Kelly2014-03-111-2/+2

* | strings: Remove cmStdString referencesBen Boeckel2014-03-081-5/+5
| | | | | | | | | | | | | | | | | | | | | | Casts from std::string -> cmStdString were high on the list of things taking up time. Avoid such implicit casts across function calls by just using std::string everywhere. The comment that the symbol name is too long is no longer relevant since modern debuggers alias the templates anyways and the size is a non-issue since the underlying methods are generated since it's inherited.

* | stringapi: Use strings for variable namesBen Boeckel2014-03-081-5/+6

|/ | | | Property names are always generated by CMake and should never be NULL.
* cmVersion: Fix CMake_VERSION_ENCODE for date in patch levelBrad King2014-02-101-1/+1
| | | | | | | | | Use a uint64_t to store encoded version numbers so we have plenty of bits available. Encode with room for up to 1000 minor releases between major releases and to encode dates until the year 10000 in the patch level. This is necessary because CMake development versions prior to release 2.8.0 used the date in the patch level, and this practice may be restored after the 3.0 release.
* Use cmsys::[io]fstream instead of cmsys_ios::[io]fstream.Clinton Stimpson2014-01-071-3/+3

* Drop builtin property documentationBrad King2013-10-161-62/+0

* CLI: Suppress the unused warning if the key value pair is cached.Stephen Kelly2013-06-041-0/+4
| | | | | | | | | | | | | | | It is common to specify a CMAKE_TOOLCHAIN_FILE and get a warning for using it despite it not being used. The WarnUnusedCliUnused test relies on the warning being emitted each time cmake is run on an existing build. That behavior is changed by this patch to warn only on the first invokation of CMake, and not on subsequent invokations (because the variable is in the cache with the same value). For that test, a clean target is added which clears the cache and cause the warning to be emitted each time. As the Ninja generator does not support the feature needed to test this, it is not tested with that generator.
