* cmListFileLexer: bail out on seek-errorsGregor Jasny2017-02-271-0/+1
| | | | | | | If we are given a FIFO, for example, we cannot seek back after trying to read a Byte-Order-Mark. Closes: #16607
* cmListFileLexer: Fix signature of cmListFileLexer_NewBrad King2017-01-111-1/+1
| | | | | Add explicit `(void)` instead of an empty argument list, as suggested by `-Wstrict-prototypes`.
* 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copyright/license notice headers that spell out copyright holder names and years are hard to maintain and often out-of-date or plain wrong.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 Robot2016-05-161-4/+2
| | | | | | | | | | | | | 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.
* Add Lua-style long brackets and long comments to CMake languageBrad King2013-10-171-0/+3
| | | | | | | | | | | | | | | | | Teach the CMake language parser to recognize Lua-style "long bracket" arguments. These start with two '[' separated by zero or more '=' characters e.g. "[[" or "[=[" or "[==[". They end with two ']' separated by the same number of '=' as the opening bracket. There is no nesting of brackets of the same level (number of '='). No escapes, variable expansion, or other processing is performed on the content between such brackets so they always represent exactly one argument. Also teach CMake to parse and ignore "long comment" syntax. A long comment starts with "#" immediately followed by an opening long bracket. It ends at the matching close long bracket. Teach the RunCMake.Syntax test to cover long bracket and long comment cases.
* cmListFileLexer: Allow a leading UTF-8 Byte-Order-Mark (#11137)Brad King2013-10-171-1/+13
| | | | | | Teach the lexer to read a UTF-8, UTF-16 BE/LE, or UTF-32 BE/LE Byte-Order-Mark from the start of a file if any is present. Report an error on files using UTF-16 or UTF-32 and accept a UTF-8 or missing BOM.
* Warn about arguments not separated by whitespaceBrad King2013-08-081-0/+1
| | | | | | | | | | | Teach the lexer to return tokens for whitespace. Teach the parser to tolerate the space tokens where whitespace is allowed. Also teach the parser to diagnose and warn about cases of quoted arguments followed immediately by another argument. This was accidentally allowed previously, so we only warn. Update the RunCMake.Syntax test case StringNoSpace expected stderr to include the warnings.
* 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.
