2018-10-31render.c: reset last_breakable after cr.John MacFarlane
Fixes jgm/pandoc#5033.
2018-10-08Fix a typo in houdini_href_e.cFelix Yan
2018-10-04commonmark writer: use ~~~ fences if info string contains backtick.John MacFarlane
This is needed for round-trip tests.
2018-10-04Update scanners for new info string rules.John MacFarlane
2018-09-14Merge pull request #257 from pclouds/xml-space-preserveJohn MacFarlane
Add xml:space="preserve" in XML output when appropriate
2018-09-09Check for whitespace before reference title.John MacFarlane
Closes #263.
2018-09-05build: only attempt to install MSVC system libraries on WindowsSaleem Abdulrasool
Newer versions of CMake attempt to query the system for information about the VS 2017 installation. Unfortunately, this query fails on non-Windows systems when cross-compiling: cmake_host_system_information does not recognize <key> VS_15_DIR CMake will not find these system libraries on non-Windows hosts anyways, and we were silencing the warnings, so simply omit the installation when cross-compiling to Windows.
2018-08-26Simplify code normalization, in line with spec change.John MacFarlane
2018-08-25Code span spec changes.John MacFarlane
These affect both parsing and writing commonmark.
2018-07-07Add xml:space="preserve" in XML output when appropriateNguyễn Thái Ngọc Duy
With current HTML escaping, sometimes we may produce an XML tag like <code_block> </code_block> Many XML parsers consider these spaces insignificant and strip them out but we need this. There's actually a test case like this in spec.txt (search "A code block can have all empty lines as its content:") and without proper hinting, an external xml->html converter will fail the spec. XML standard covers this case. If xml:space is "preserve", then whitespaces are significant and should be kept. Add this hint for text, code, code_block, html_inline and html_block tags.
2018-06-11Removed meta from list of block tags.John MacFarlane
Added regression test. See commonmark/CommonMark#527.
2018-04-14Optimize S_find_first_nonspace.John MacFarlane
We were needlessly redoing things we'd already done. Now we skip the work if the first nonspace is greater than the current offset. This fixes pathological slowdown with deeply nested lists (#255). For N = 3000, the time goes from over 17s to about 0.7s. Thanks to @mity for diagnosing the problem.
2018-03-25Allow spaces in link destination delimited with pointy brackets.John MacFarlane
To conform to recent spec change.
2018-03-25Adjust max length of decimal/numeric entities.John MacFarlane
See commonmark/CommonMark#487.
2018-03-25Fix inline raw HTML parsing.John MacFarlane
This fixes a recently added failing spec test case. Previously spaces were being allowed in unquoted attribute values; no we forbid them.
2018-03-25Don't allow list markers to be indented >= 4 spaces.John MacFarlane
See commonmark/CommonMark#497.
2018-02-20Check for empty buffer when renderingPhil Turnbull
For empty documents, `->size` is zero so `renderer.buffer->ptr[renderer.buffer->size - 1]` will cause an out-of-bounds read. Empty buffers always point to the global `cmark_strbuf__initbuf` buffer so we read `cmark_strbuf__initbuf[-1]`.
2017-11-14Generate export header for static-only buildNick Wellnhofer
Fixes issue #247.
2017-11-05Merge pull request #217 from github/upstream/limit-nested-parensJohn MacFarlane

2017-11-02Merge branch 'master' into upstream/inline-sourceposAshe Connor
2017-10-19Include GNUInstallDirs in src/CMakeLists.txtNick Wellnhofer
Fixes installation error under some CMake versions, notably kalakris' CMake backport often used with Travis.
2017-10-12Fixed regression in install dest for static library.John MacFarlane
Due to a mistake, 0.28.1 installed libcmark.a into include/. Closes #238.
2017-10-10Don't use CMAKE_INSTALL_LIBDIR to create libcmark.pc.John MacFarlane
For some reason this wasn't getting set in processing libcmark.pc.in, and we were getting the wrong entry in libcmark.pc. (See #236) The new approach sets an internal libdir variable to lib${LIB_SUFFIX}. This variable is used both to set the install destination and in the libcmark.pc.in template. Closes #236. However, I'd welcome comments from @juhp who originally added CMAKE_INSTALL_LIBDIR in #185. I think that the new system should work fine with Fedora, since LIB_SUFFIX will be set appropriately, but some testing is in order.

2017-07-11Merge pull request #213 from github/upstream/undefined-shiftJohn MacFarlane
Use unsigned integer when shifting
2017-07-11Use unsigned integer when shiftingPhil Turnbull
A UBSAN warning can be triggered when handling a long sequence of backticks: src/commonmark.c:98:20: runtime error: left shift of 1 by 31 places cannot be represented in type 'int' which can be triggered by: ``` | a | b | | --- | --** `c```````````````````````````````- | | c | `|d` \| e | ```
2017-07-06Avoid memcpy'ing NULL pointersPhil Turnbull
A UBSAN warning can be triggered because the link title is an empty string: src/inlines.c:113:20: runtime error: null pointer passed as argument 2, which is declared to never be null which can be triggered by: ``` [f]:_ [f] ``` The length of the memcpy is zero so the NULL pointer is not dereferenced but it is still undefined behaviour.
2017-06-29DeMorgan simplification of some tests in emphasis parser.John MacFarlane
This also brings the code into closer alignment with the wording of the spec. See jgm/CommonMark#467.
2017-06-29Fixed undefined shift in commonmark writer.John MacFarlane
Closes #211. Found by google/oss-fuzz: https://oss-fuzz.com/v2/testcase-detail/4686992824598528
2017-06-29latex writer: fix memory overflow.John MacFarlane
We got an array overflow in enumerated lists nested more than 10 deep with start number =/= 1. Found by google/oss-fuzz. https://oss-fuzz.com/v2/testcase-detail/5546760854306816 This commit also ensures that we don't try to set `enum_` counters that aren't defined by LaTeX (generally up to enumv). Closes #210.

echo '[](xx:)' | ./build/src/cmark -t latex Segmentation fault: 11
2017-06-27Add Makefile target and harness to fuzz with libFuzzerPhil Turnbull
This can be run locally with `make libFuzzer` but the harness will be integrated into oss-fuzz for large-scale fuzzing.
