2017-01-20Fixed buffer overflow error in S_parser_feed.John MacFarlane
The overflow could occur in the following condition: the buffer ends with `\r` and the next memory address contains `\n`. Closes #184.
2017-01-08Update emphasis parsing for spec change.John MacFarlane
Strong now goes inside Emph rather than the reverse, when both scopes are possible. The code is much simpler. This also avoids a spec inconsistency that cmark had previously: `***hi***` became Strong (Emph "hi")) but `***hi****` became Emph (Strong "hi")) "*"
2017-01-07Fixes for the LaTeX renderer (#182)Doeme
* Don't double-output the link in latex-rendering. * Prevent ligatures in dashes sensibly when rendering latex. \- is a hyphenation, so it doesn't get displayed at all. * Redo "Don't double-output the link in latex-rendering." This reverts commit 8fb1f1c3c8799628141780ca5fd8d70883c1ec53 and adds the proper solution to the problem. With commit 8fb1f1c3c double rendering is fixed, but the url isn't escaped anymore, so I discarded the wrong copy. We now return 0 from the function in case of a single link, which stops processing the contents of the node. * Add a comment about the double-rendering issue addressed in 1c0d4749451cf85a849a3cf8e41cf137789821d4

CMake impovement
2017-01-06Make shared and static libraries optionalAzamat H. Hackimov
Now you can enable/disable compilation and installation targets for shared and static libraries via -DCMARK_SHARED=ON/OFF and -DCMARK_STATIC=ON/OFF
2017-01-06Added support for built-in ${LIB_SUFFIX} featureAzamat H. Hackimov
Replaced ${LIB_INSTALL_DIR} option with built-in ${LIB_SUFFIX} for installing for 32/64-bit systems. Normally, CMake will set ${LIB_SUFFIX} automatically for required enviroment. If you have any issues with it, you can override this option with -DLIB_SUFFIX=64 or -DLIB_SUFFIX="" during configuration.

2017-01-03Fix "multiple of 3" determination in emph/strong parsing.John MacFarlane
We need to store the length of the original delimiter run, instead of using the length of the remaining delimiters after some have been subtracted. Test case: a***b* c* Thanks to Raph Levin for reporting.
2016-12-30Change types for source map offsets (#174)Nick Wellnhofer
* Improve strbuf guarantees Introduce BUFSIZE_MAX macro and make sure that the strbuf implementation can handle strings up to this size. * Abort early if document size exceeds internal limit * Change types for source map offsets Switch to size_t for the public API, making the public headers C89-compatible again. Switch to bufsize_t internally, reducing memory usage and improving performance on 32-bit platforms. * Make parser return NULL on internal index overflow Make S_parser_feed set an error and ignore subsequent chunks if the total input document size exceeds an internal limit. Make cmark_parser_finish return NULL if an error was encountered. Add public API functions to retrieve error code and error message. strbuf overflow in renderers and OOM in parser or renderers still cause an abort.

2016-12-09Correctly initialize chunk in S_process_line (#170)Nick Wellnhofer
The `alloc` member wasn't initialized. This also allows to add an assertion in `chunk_rtrim` which doesn't work for alloced chunks.

2016-11-26Inlines: Ensure that the delimiter stack is freed in subject.John MacFarlane
2016-11-26Fixed pathological cases with backtick code spans:John MacFarlane
- Removed recursion in scan_to_closing_backticks - Added an array of pointers to potential backtick closers to subject - This array is used to avoid traversing the subject again when we've already seen all the potential backtick closers. - Added a max bound of 1000 for backtick code span delimiters. - This helps with pathological cases like: x x ` x `` x ``` x ```` ... Thanks to Martin Mitáš for identifying the problem and for discussion of solutions.

2016-11-09Fix CMAKE_C_VISIBILITY_PRESET for cmake versions greater than 1.8 (e.g. ↵Hugh Bellamy
3.6.2) (#162) This lets us build swift-cmark on Windows, using clang-cl This was an oversight: CMAKE_C_VISIBILITY_PRESET is only available on CMAKE 1.8 or greater. However, the current check doesn't work for a version such as CMAKE 3.6.2, for example ```bash mkdir "C:/Users/hughb/Documents/GitHub/my-swift/build/Ninja-DebugAssert/cmark-windows-amd64" pushd "C:/Users/hughb/Documents/GitHub/my-swift/build/Ninja-DebugAssert/cmark-windows-amd64" cmake -G Ninja -DCMAKE_C_COMPILER="C:/Program Files/LLVM/msbuild-bin/cl.exe" -DCMAKE_CXX_COMPILER="C:/Program Files/LLVM/msbuild-bin/cl.exe" -DCMAKE_CXX_FLAGS="-Xclang -std=c++14" "C:/Users/hughb/Documents/GitHub/my-swift/cmark" popd cmake --build "C:/Users/hughb/Documents/GitHub/my-swift/build/Ninja-DebugAssert/cmark-windows-amd64/" -- -j6 all ```
2016-11-04Fix for non-matching entities (#161)Yuki Izumi
* Add test to illustrate issue * Provide some test fixes * Don't neglect CounterClockwiseContourIntegral * Fix ~10% of cases not matching strncmp returns 0 if the first 'len' bytes of cmark_entities[i].entity match s; we check equal length in the first if by checking if cmark_entities[i].entity[len] == 0, but we neglect the case where cmp == 0 && cmark_entities[i].entity[len] != 0. This should be treated as the same as cmp < 0, because strcmp("abc", "abcd") < 0. * Don't depend on py3.3 in tests

2016-10-11Changed logic for null/eol checks.John MacFarlane
- only check once for "not at end of line" - check for null before we check for newline characters (the previous patch would fail for NULL + CR) See #160.
