* 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copyright/license notice headers that spell out copyright holder names and years are hard to maintain and often out-of-date or plain wrong.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.
* Fortran: Add support for submodule syntax in dependency scanningBrad King2016-09-201-1/+6
| | | | | | | | | | | | | | | | | | | Fortran 2008 [1] adds support for a new syntax related to modules: submodule ( ParentModule ) SubModule submodule ( ParentModule : SubModule ) NestedSubModule Both of these mean that the current source file requires the module `ParentModule` to be available if it is not provided in the current file. Teach our Fortran dependency scanner to parse this syntax to extract this relationship. For now simply tolerate the nested submodule case and extract only the dependency it expresses on the main module. Further work will be needed to extract dependencies among nested submodules.

* cmFortranParser: Parse keywords as lexical tokensBrad King2016-09-081-0/+6
| | | | | | | | Teach the lexer to match and return specific Fortran keywords as tokens. Update the parser to use these instead of always using a WORD token and then checking the text. This avoids extra string comparisons and will allow more grammar productions to be unambiguously added later for additional Fortran statements.
* cmFortranLexer: Update to flex 2.6Brad King2016-09-061-12/+5
| | | | | | Revise the documented modifications we need to make to the flex-generated source file according to the needs of the new version. Also drop the duplicate copyright notice block from the generated file.
* Fix spelling typos in comments and documentation (#16037)Felix Geyer2016-03-291-1/+1
| | | | | The Debian package checker tool (lintian) detected several typos in CMake.
* cmFortranParser: Parse #line directivesBrad King2015-11-021-1/+2
| | | | | | | Teach the lexer to extract the #line directive prefix and line number as a new token type. Teach the parser to recognize this token followed by a string as the file name (plus possibly other content). Report the named file as included by the source file.
* Rename Fortran parser infrastructure to drop "Depends" prefixKitware Robot2015-07-271-0/+190
The parser can be re-used outside cmDependsFortran or the cmDepends class hierarchy so drop the "Depends" from its name: rename 's/DependsFortran([A-Za-z0-9_])/Fortran$1/' Source/*.* sed -i 's/DependsFortran\([A-Za-z0-9_]\)/Fortran\1/g' Source/*.* sed -i 's/FortranInternals/DependsFortranInternals/g' Source/*.* Also manually fix Source/CMakeLists.txt source file ordering.
