cmark: updated to 0.31.1

0.31.1

* Flag root node as open in `cmark_parser_new_with_mem_into_root`

* Remove `source`, add `search` to list of block tags
  (a spec 0.31 change we forgot in last release).

* Accept lowercase inline HTML declarations (Michael Howell).

* Remove unused functions (Nick Wellnhofer).

* utf8:

  + Fix encoding of U+FFFE and U+FFFF
  + Rework case folding (Nick Wellnhofer).  Using a table and binary
    search instead of a generated switch statement significantly
    reduces the size of the compiled code.

* houdini:

  + Rename `houdini_escape_html0` -> `houdini_escape_html`
  + Rework HTML entity table (Nick Wellnhofer).
    The new layout saves about 20 KB and removes 50 KB of relocation
    entries from the shared library, also speeding up loading.

* cmake:

  + Tell cmake to set `rpath` so the installed `cmark` can find
    `libcmark.so` (Michael Witten).
  + Remove unnecessary enabling of target property: MACOSX_RPATH
    (Michael Witten).
  + Fix build type checks (Nick Wellnhofer). Make the libFuzzer
    target use the Asan build type again.

* Makefile:

  + Fix `libFuzzer` target (Nick Wellnhofer).
  + Use `ctest` and `--output-on-failure` in `test` target.
  + `make debug` should build a shared library (Nick Wellnhofer).
    The full test suite is only available to a shared library build.

* wrappers:

  + Fix memory leak in Ruby wrapper (Nick Wellnhofer).
    Free the string returned from `cmark_markdown_to_html`.
    Fix `cmark_markdown_to_html` argument types.
  + Fix memory leak in Python wrapper (Nick Wellnhofer).
    Free the string returned from cmark_markdown_to_html.
    Fix cmark_markdown_to_html argument types.
  + Convert to and from UTF-8 under Python 2.
  + Add PHP wraper (Vinicius Dias).

* ci:

  + Test with ASan and rework CI matrix (Nick Wellnhofer).
  + Remove the valgrind leakcheck test. This should be covered now
    by testing with LeakSanitizer on static builds, including tests
    like spectest_executable. The full test suite is only available
    to shared library builds which have to run without leak checks
    for now.
  + Separate cflags from cc (Nick Wellnhofer).
  + Make CMake matrix options work (Nick Wellnhofer).
    CMAKE_OPTIONS had no effect, leading to the shared library not being
    tested. Invoke cmake directly, so we don't have to deal with the mess
    in Makefile.
  + Do debug build so that assertions will run
  + Use `-gdwarf-4` with clang for compatibility with valgrind

* test:

  + Fix memory leaks in cmark.py (Nick Wellnhofer).
    Free results of libcmark API function calls.
  + Fix memory leaks in api_test (Nick Wellnhofer).
  + Simplify test execution environment handling (Saleem Abdulrasool).
    Use generator expressions to compute the new path and avoid
    translations. This reduces complexity in the build and allows for a
    different build layout.

* fuzz: Test more parser entry points (Nick Wellnhofer).

* Remove superfluous definitions from scanners.re.

* re2c: Disable UTF-8 (Nick Wellnhofer). The regexes don't require UTF-8
  features and work in ASCII mode as well. Disabling UTF-8 reduces the
  size of the code generated by re2c.

cmark: updated to 0.31.0

0.31.0

* Update to 0.31.2 spec.txt.

* Treat unicode Symbols like Punctuation, as per the 0.31 spec.

* Add a new function to `utf8.h`:
  `int cmark_utf8proc_is_punctuation_or_symbol(int32_t uc)`.
  The old `cmark_utf8proc_is_punctuation` has been kept for
  now, but it is no longer used.

* Add new exported function `cmark_parser_new_with_mem_into_root`
  (API change) (John Ericson).

* Avoid repeated `language-` in info string

* Fix quadratic behavior in `S_insert_emph` (Nick Wellnhofer).
  Fixes part of GHSA-66g8-4hjf-77xh.

* Fix quadratic behavior in `check_open_blocks` (Nick Wellnhofer).
  Fixes part of GHSA-66g8-4hjf-77xh.

* Track underscore bottom separately mod 3, like asterisk (Michael
  Howell). This was already implemented correctly for asterisks,
  but not for underscore.

* Use `fwrite` instead of `printf` to print results in main
  This avoids a massive slowdown in MSYS2.

* commonmark writer: less aggressive escaping for `!`

* Update libFuzzer build (Nick Wellnhofer):

  + Move fuzzing files into their own directory.
  + Use libFuzzer the modern way by compiling and linking with
    `-fsanitize=fuzzer(-no-link)` without requiring `LIB_FUZZER_PATH`.
  + Update the `libFuzzer` rule in Makefile and the README.md.

* CMake build changes (Saleem Abdulrasool).

  + Inline multiple variables in CMake, following CMake recommendations.
  + Simplify the version computation.
  + Remove the `CMARK_STATIC` and `CMARK_SHARED` options as one of the two
    must be enabled always as the cmark executable depends on the library.
    Instead of having a custom flag to discern between the
    library type, use the native CMake option `BUILD_SHARED_LIBS`,
    allowing the user to control which library to build. This matches
    CMake recommendations to only build a single copy of the library.
  + Introduce an author warning for the use of `CMARK_SHARED` and
    `CMARK_STATIC` to redirect the author of the dependent package to
    `BUILD_SHARED_LIBS`.
  + Permit incremental linking on Windows. Although incremental linking
    does introduce padding in the binary for incremental links, that
    should not matter for release mode builds in theory as `/OPT:REF`
    and `/OPT:ICF` will trigger full links, which is the default in
    release mode.
  + Hoist the CMake module inclusion to the top level.
  + Minor tweaks for speeding up the configure phase.
    Restructure the file layout to place the custom modules into the
    `cmake/modules` directory that is the common layout for CMake based
    projects.
  + Squelch C4232 warnings on MSVC builds.
  + Remove check for `__builtin_expect`. Use `__has_builtin` to check
    at compile time if the feature is supported.
    This macro is supported by both clang and GCC (as of 10).
    In the case that the compiler in use is not new enough, we still
    provide the fallback so that the code will compile but without the
    additional hints for the branch probability. `config.h` has been
    removed from the code base as it is no longer needed.
  + Remove `/TP` usage on MSVC and replace `CMARK_INLINE` with `inline`.
    These were workarounds for pre-VS2015 compilers, which are no longer
    supported.
  + Hoist the C visibility settings to top level
  + Clean up C4267 warnings on MSVC builds.
  + Remove some compiler compatibility checks that are no longer
    needed because VS 2013 is no longer supported
  + Adjust the policy to silence warnings on MSVC builds
    CMake 3.15+ remove `/W3` from the language flags under MSVC with
    CMP0092.  Set the policy to new to avoid the D9025 warning.
  + Reflow some text to match CMake documentation style
  + Use generator expression for path computation.
  + Use CMake to propagate `CMARK_STATIC_DEFINE`.
  + Clean up an obsoleted variable (NFC).
  + Hoist the policy settings. Policy settings may impact how
    `project` functions.  They should be set immediately after
    `cmake_minimum_required` (which implicitly sets policies).
    Use the `POLICY` check to see if a policy is defined rather
    than using a version check.
  + Replace `CMARK_TESTS` with CMake sanctioned `BUILD_TESTING`.
  + Correct typo and adjust command invocation. Use the proper
    generator expression for the python interpreter and adjust
    a typo in the component name.
  + Add an upgrade path for newer CMake.
    CMake 3.12 deprecated `FindPythonInterp`, and with CMake 3.27, were
    obsoleted with CMP0148.  Add a version check and switch to the new
    behaviour to allow building with newer releases.

* Fix regex syntax warnings in `pathological_tests.py` (Nick Wellnhofer).

* `test/cmark.py`: avoid star imports (Jakub Wilk).

* `spec_tests.py`: Add option to generate fuzz corpus (Nick Wellnhofer).
  Add an option `--fuzz-corpus` that writes the test cases to separate
  files including the options header, so they can be used as seed corpus
  for fuzz testing.

* Fix some cmark.3 man rendering issues so we can do a clean regen
  (John Ericson).

* Update Windows compilation instructions

*: recursive bump for Python 3.11 as new default

cmark: updated to 0.30.3

0.30.3

* Fix quadratic complexity bug with repeated `![[]()`.
  Resolves CVE-2023-22486. Add new pathological test.

* Allow declarations with no space, as per spec.

* Set `enumi*` counter correctly in LaTeX output.

* Allow `<!DOCTYPE` to be case-insensitive. (This conforms to the
  existing spec.)

* Fixed HTML comment scanning. Need to handle this case: `<!--> and -->`.
  Since the scanner finds the longest match, we had to
  move some of the logic outside of the scanner.

* Fix quadratic parsing issue with repeated `<!--` (this was not
  introduced by the previous fix, and not in a released version of cmark).
  Resolves CVE-2023-22484. Add new pathological test.

* Update HTML comment scanner to accord with commonmark/commonmark-spec#713.

* Pathological tests: half the number of repetitions, and the timeout.
  This reduces the time needed for the pathological tests.

* Shrink `struct cmark_node`. The `internal_offset` member is
  only used for headings and can be moved to `struct cmark_heading`.
  This reduces the size of `struct cmark_node` from 112 to 104 bytes on
  64-bit systems.

* Add `-Wstrict-prototypes` and fix offending functions.

* Fix quadratic behavior involving `get_containing_block`.
  Instead of searching for the containing block, update the tight list
  status when entering a child of a list item or exiting a list.

* Fix `pathological_tests.py`:
  - Use a multiprocessing.Queue to actually get results from spawned
    tests processes.
  - Fix the `allowed_failures` test.
  - Truncate actual output when printed.
  - Prepare for testing pathological behavior of the Commonmark renderer.

* Fix source position bug with backticks (kyle).

cmark: Fix building dependencies with strict function prototypes

cmark: updated to 0.30.2

0.30.2

* Fix parsing of emphasis before links.
  Fixes a regression introduced with commit ed0a4bf.

* Update to Unicode 14.0 (data-man).

* Add `~` to safe href character set.

* Update CMakeLists.txt.  Bump the minimum required
  CMake to 3.7. Imperatively define output name for static library.

* Fix install paths in libcmark.pc.
  `CMAKE_INSTALL_<dir>` can be relative or absolute path, so it is wrong to
  prefix CMAKE_INSTALL_PREFIX because if CMAKE_INSTALL_<dir> is set to an
  absolute path it will result in a malformed path with two absolute paths
  joined together.  Instead, use `CMAKE_INSTALL_FULL_<dir>` from
  GNUInstallDirs.

cmark: updated to 0.30.1

[0.30.1]

  * Properly indent block-level contents of list items in man.
    This handles nested lists as well as items with multiple paragraphs.
    The change requires addition of a new field block_number_in_list_item
    to cmark_renderer, but this does not change the public API.
  * Fix quadratic behavior when parsing emphasis (Nick
    Wellnhofer).  Delimiters can be deleted, so store delimiter positions
    instead of pointers in `openers_bottom`. Besides causing undefined
    behavior when reading a dangling pointer, this could also result
    in quadratic behavior when parsing emphasis.
  * Fix quadratic behavior when parsing smart quotes (Nick Wellnhofer).
    Remove matching smart quote delimiters.  Otherwise, the same opener
    could be found over and over, preventing the `openers_bottom`
    optimization from kicking in and leading to quadratic behavior when
    processing lots of quotes.
  * Modify CMake configuration so that the project can be built with
    older versions of CMake (Saleem Abdulrasool).  (In 0.30.0,
    some features were used that require CMake >= 3.3.) The cost of this
    backwards compatibility is that developers must now explicitly invoke
    `cmark_add_compile_options` when a new compilation target is added.
  * Remove a comma at the end of an enumerator list, which was flagged
    by clang as a C++11 extension.
  * make_man_page.py: use absolute path with CDLL. This avoids the error
    "file system relative paths not allowed in hardened programs."
  * Include cmark version in cmark(3) man page (instead of LOCAL).

[0.30.0]

  * Use official 0.30 spec.txt.
  * Add `cmark_get_default_mem_allocator()`.  API change: this
    adds a new exported function in cmark.h.
  * An optimization we used for emphasis parsing was
    too aggressive, causing us to miss some emphasis that was legal
    according to the spec.  We fix this by indexing the `openers_bottom`
    table not just by the type of delimiter and the length of the
    closing delimiter mod 3, but by whether the closing delimiter
    can also be an opener.  (The algorithm for determining emphasis
    matching depends on all these factors.)  Add regression test.
  * Fix quadratic behavior with inline HTML (Nick Wellnhofer).
    Repeated starting sequences like `<?`, `<!DECL ` or `<![CDATA[` could
    lead to quadratic behavior if no matching ending sequence was found.
    Separate the inline HTML scanners. Remember if scanning the whole input
    for a specific ending sequence failed and skip subsequent scans.
  * Speed up hierarchy check in tree manipulation API (Nick Wellnhofer).
    Skip hierarchy check in the common case that the inserted child has
    no children.
  * Fix quadratic behavior when parsing inlines (Nick Wellnhofer).
    The inline parsing code would call `cmark_node_append_child` to append
    nodes. This public function has a sanity check which is linear in the
    depth of the tree. Repeated calls could show quadratic behavior in
    degenerate trees. Use a special function to append nodes without this
    check.  (Issue found by OSS-Fuzz.)
  * Replace invalid characters in XML output (Nick wellnhofer).
    Control characters, U+FFFE and U+FFFF aren't allowed in XML 1.0, so
    replace them with U+FFFD (replacement character). This doesn't solve
    the problem how to roundtrip these characters, but at least we don't
    produce invalid XML.
  * Avoid quadratic output growth with reference links (Nick Wellnhofer).
    Keep track of the number bytes added through expansion of reference
    links and limit the total to the size of the input document. Always
    allow a minimum of 100KB.  Unfortunately, cmark has no error handling,
    so all we can do is to stop expanding reference links without returning
    an error. This should never be an issue in practice though. The 100KB
    minimum alone should cover all real-world cases.
  * Fix issue with type-7 HTML blocks interrupting paragraphs
    (see commonmark/commonmark.js).
  * Treat `textarea` like `script`, `style`, `pre` (type 1 HTML block),
    in accordance with spec change.
  * Define whitespace per spec (Asherah Conor).
  * Add `MAX_INDENT` for xml.  Otherwise we can get quadratic
    increase in size with deeply nested structures.
  * Fix handling of empty strings when creating XML/HTML output
    (Steffen Kieß).
  * Commonmark renderer: always use fences for code.
    This solves problems with adjacent code blocks being merged.
  * Improve rendering of commonmark code spans with spaces.
  * Cleaner approach to max digits for numeric entities.
    This modifies unescaping in `houdini_html_u.c` rather than
    the entity handling in `inlines.c`.  Unlike the other,
    this approach works also in e.g. link titles.
  * Fix entity parser (and api test) to respect length limit on
    numeric entities.
  * Don't allow link destinations with unbalanced unescaped parentheses.
    See commonmark/commonmark.js.
  * `print_usage()`: Minor grammar fix, swap two words (Øyvind A. Holm).
  * Don't call `memcpy` with `NULL` as first parameter.
    This is illegal according to the C standard, sec. 7.1.4.
    See <https://www.imperialviolet.org/2016/06/26/nonnull.html>.
  * Add needed include in `blocks.c`.
  * Fix unnecessary variable assignment.
  * Skip UTF-8 BOM if present at beginning of buffer.
  * Fix URL check in `is_autolink` (Nick Wellnhofer).  In a recent commit,
    the check was changed to `strcmp`, but we really have to use `strncmp`.
  * Fix null pointer deref in `is_autolink` (Nick Wellnhofer).
    Introduced by a recent commit. Found by OSS-Fuzz.
  * Rearrange struct cmark_node (Nick Wellnhofer).  Introduce multi-purpose
    data/len members in struct cmark_node. This is mainly used to store
    literal text for inlines, code and HTML blocks.
    Move the content strbuf for blocks from `cmark_node` to `cmark_parser`.
    When finalizing nodes that allow inlines (paragraphs and headings),
    detach the strbuf and store the block content in the node's data/len
    members. Free the block content after processing inlines.
    Reduces size of struct `cmark_node` by 8 bytes.
  * Improve packing of `struct cmark_list` (Nick Wellnhofer).
  * Use C string instead of chunk in a number of contexts (Nick Wellnhofer).
    The node struct never references memory of other nodes now.
    Node accessors don't have to check for delayed creation of C strings,
    so parsing and iterating all literals using the public API should
    actually be faster than before.  These changes also reduce the size
    of `struct cmark_node`.
  * Add casts for MSVC10 (from kivikakk in cmark-cfm).
  * commonmark renderer:  better escaping in smart mode.  When
    `CMARK_OPT_SMART` is enabled, we escape literal `-`, `.`, and quote
    characters when needed to avoid their being "smartified."
  * Add options field to `cmark_renderer`.
  * commonmark.c - use `size_t` instead of `int`.
  * Include `string.h` in `cmark-fuzz.c`.
  * Fix (hash collisions for references) (Vicent Marti via cmark-gfm).
    Reimplemented reference storage as follows:
    1. New references are always inserted at the end of a linked list. This
    is an O(1) operation, and does not check whether an existing (duplicate)
    reference with the same label already exists in the document.
    2. Upon the first call to `cmark_reference_lookup` (when it is expected
    that no further references will be added to the reference map), the
    linked list of references is written into a fixed-size array.
    3. The fixed size array can then be efficiently sorted in-place in O(n
    log n). This operation only happens once. We perform this sort in a
    _stable_ manner to ensure that the earliest link reference in the
    document always has preference, as the spec dictates. To accomplish
    this, every reference is tagged with a generation number when initially
    inserted in the linked list.
    4. The sorted array is then compacted in O(n). Since it was sorted in a
    stable way, the first reference for each label is preserved and the
    duplicates are removed, matching the spec.
    5. We can now simply perform a binary search for the current
    `cmark_reference_lookup` query in O(log n). Any further lookup calls
    will also be O(log n), since the sorted references table only needs to
    be generated once.
    The resulting implementation is notably simple (as it uses standard
    library builtins `qsort` and `bsearch`), whilst performing better than
    the fixed size hash table in documents that have a high number of
    references and never becoming pathological regardless of the input.
  * Comment out unused function `cmark_strbuf_cstr` in `buffer.h`.
  * Re-add `--safe` command-line option as a no-op, for backwards
    compatibility.
  * Update to Unicode 13.0
  * Generate and install cmake-config file (Reinhold Gschweicher).
    Add full cmake support. The project can either be used with
    `add_subdirectory` or be installed into the system (or some other
    directory) and be found with `find_package(cmark)`. In both cases the
    cmake target `cmark::cmark` and/or `cmark::cmark_static` is all that
    is needed to be linked.  Previously the `cmarkConfig.cmake` file
    was generated, but not installed.  As additional bonus of generation
    by cmake we get a generated `cmake-config-version.cmake` file for
    `find_package()` to search for the same major version.
    The generated config file is position independent, allowing the
    installed directory to be copied or moved and still work.
    The following four files are generated and installed:
    `lib/cmake/cmark/cmark-config.cmake`,
    `lib/cmake/cmark/cmark-config-version.cmake`,
    `lib/cmake/cmark/cmark-targets.cmake`,
    `lib/cmake/cmark/cmark-targets-release.cmake`.
  * Adjust the MinGW paths for MinGW64 (Daniil Baturin).
  * Fix CMake generator expression checking for MSVC (Nick Wellnhofer).
  * Fix `-Wconst-qual` warning (Saleem Abdulrasool).  This enables building
    with `/Zc:strictString` with MSVC as well.
  * Improve and modernize cmake build (Saleem Abdulrasool).
    + Build: add exports targets for build tree usage.
    + Uuse target properties for include paths.
    + Remove the unnecessary execute permission on CMakeLists.txt.
    + Reduce property computation in CMake.
    + Use `CMAKE_INCLUDE_CURRENT_DIRECTORY`.
    + Improve man page installation.
    + Only include `GNUInstallDirs` once.
    + Replace `add_compile_definitions` with `add_compile_options`
      since the former was introduced in 3.12.
    + Cleanup CMake.
    + Inline a variable.
    + Use `LINKER_LANGUAGE` property for C++ runtime.
    + Use CMake to control C standard.
    + Use the correct variable.
    + Loosen the compiler check
    + Hoist shared flags to top-level CMakeLists
    + Remove duplicated flags.
    + Use `add_compile_options` rather than modify `CMAKE_C_FLAGS`.
    + Hoist sanitizer flags to global state.
    + Hoist `-fvisibilty` flags to top-level.
    + Hoist the debug flag handling.
    + Hoist the profile flag handling.
    + Remove incorrect variable handling.
    + Remove unused CMake includes.
  * Remove "-rdynamic" flag for static builds (Eric Pruitt).
  * Fixed installation on other than Ubuntu GNU/Linux distributions
    (Vitaly Zaitsev).
  * Link executable with static or shared library (Nick Wellnhofer).
    If `CMARK_STATIC` is on (default), link the executable with the static
    library. This produces exactly the same result as compiling the library
    sources again and linking with the object files.
    If `CMARK_STATIC` is off, link the executable with the shared library.
    This wasn't supported before and should be the preferred way to
    package cmark on Linux distros.
    Building only a shared library and a statically linked executable
    isn't supported anymore but this doesn't seem useful.
  * Reintroduce version check for MSVC /TP flag (Nick Wellnhofer).
    The flag is only required for old MSVC versions.
  * normalize.py: use `html.escape` instead of `cgi.escape`.
  * Fix pathological_tests.py on Windows (Nick Wellnhofer).
    When using multiprocessing on Windows, the main program must be
    guarded with a `__name__` check.
  * Remove useless `__name__` check in test scripts (Nick Wellnhofer).
  * Add CIFuzz (Leo Neat).
  * cmark.1 - Document --unsafe instead of --safe.
  * cmark.1: remove docs for `--normalize` which no longer exists.
  * Add lint target to Makefile.
  * Add uninstall target to Makefile.
  * Update benchmarks.
  * Fix typo in documentation (Tim Gates).
  * Increase timeout for pathological tests to avoid CI failure.
  * Update the Racket wrapper with the safe -> unsafe flag change

PKGREVISION bump for anything using python without a PYPKGPREFIX.

This is a semi-manual PKGREVISION bump.

cmark: updated to 0.29.0

0.29.0:
Update spec to 0.29.
Make rendering safe by default. Adds CMARK_OPT_UNSAFE and make CMARK_OPT_SAFE a no-op (for API compatibility). The new default behavior is to suppress raw HTML and potentially dangerous links. The CMARK_OPT_UNSAFE option has to be set explicitly to prevent this. NOTE: This change will require modifications in bindings for cmark and in most libraries and programs that use cmark.
Add sourcepos info for inlines (Yuki Izumi).
Disallow more than 32 nested balanced parens in a link (Yuki Izumi).
Resolve link references before creating setext header. A setext header line after a link reference should not create a header, according to the spec.
commonmark renderer: improve escaping. URL-escape special characters when escape mode is URL, and not otherwise. Entity-escape control characters (< 0x20) in non-literal escape modes.
render: only emit actual newline when escape mode is LITERAL. For markdown content, e.g., in other contexts we want some kind of escaping, not a literal newline.
Update code span normalization to conform with spec change.
Allow empty <> link destination in reference link.
Remove leftover includes of memory.h.
A link destination can't start with < unless it is an angle-bracket link that also ends with >. (If your URL really starts with <, URL-escape it.)
Allow internal delimiter runs to match if both have lengths that are multiples of 3.
Include references.h in parser.h.
Fix [link](<foo\>).
Use hand-rolled scanner for thematic break. Keep track of the last position where a thematic break failed to match on a line, to avoid rescanning unnecessarily.
Rename ends_with_blank_line with S_ prefix.
Add CMARK_NODE__LAST_LINE_CHECKED flag. Use this to avoid unnecessary recursion in ends_with_blank_line.
In ends_with_blank_line, call S_set_last_line_blank to avoid unnecessary repetition. Once we settle whether a list item ends in a blank line, we don't need to revisit this in considering parent list items.
Disallow unescaped ( in parenthesized link title.
Copy line/col info straight from opener/closer (Ashe Connor). We can't rely on anything in subj since it's been modified while parsing the subject and could represent line info from a future line. This is simple and works.
render.c: reset last_breakable after cr.
Fix a typo in houdini_href_e.c (Felix Yan).
commonmark writer: use ~~~ fences if info string contains backtick. This is needed for round-trip tests.
Update scanners for new info string rules.
Add XSLT stylesheet to convert cmark XML back to Commonmark. Initial version of an XSLT stylesheet that converts the XML format produced by cmark -t xml back to Commonmark.
Check for whitespace before reference title.
Bump CMake to version 3 (Jonathan Müller).
Build: Remove deprecated call to add_compiler_export_flags() (Jonathan Müller). It is deprecated in CMake 3.0, the replacement is to set the CXX_VISIBILITY_PRESET (or in our case C_VISIBILITY_PRESET) and VISIBILITY_INLINES_HIDDEN properties of the target. We're already setting them by setting the CMake variables anyway, so the call can be removed.
Build: only attempt to install MSVC system libraries on Windows (Saleem 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.
Simplify code normalization, in line with spec change.
Implement code span spec changes. These affect both parsing and writing commonmark.
Add link parsing corner cases to regressions (Ashe Connor).
Add xml:space="preserve" in XML output when appropriate (Nguyễn Thái Ngọc Duy). (For text, code, code_block, html_inline and html_block tags.)
Removed meta from list of block tags. Added regression test.
entity_tests.py - omit noisy success output.
pathological_tests.py: make tests run faster. Commented out the (already ignored) "many references" test, which times out. Reduced the iterations for a couple other tests.
pathological_tests.py: added test for deeply nested lists.
Optimize S_find_first_nonspace. 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. For N = 3000, the time goes from over 17s to about 0.7s. Thanks to Martin Mitas for diagnosing the problem.
Allow spaces in link destination delimited with pointy brackets.
Adjust max length of decimal/numeric entities.
Fix inline raw HTML parsing. This fixes a recently added failing spec test case. Previously spaces were being allowed in unquoted attribute values; no we forbid them.
Don't allow list markers to be indented >= 4 spaces.
Check for empty buffer when rendering (Phil 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].
Also run API tests with CMARK_SHARED=OFF (Nick Wellnhofer).
Rename roundtrip and entity tests (Nick Wellnhofer). Rename the tests to reflect that they use the library, not the executable.
Generate export header for static-only build.
Fuzz width parameter too (Phil Turnbull). Allow the width parameter to be generated too so we get better fuzz-coverage.
Don't discard empty fuzz test-cases (Phil Turnbull). We currently discard fuzz test-cases that are empty but empty inputs are valid markdown. This improves the fuzzing coverage slightly.
Fixed exit code for pathological tests.
Add allowed failures to pathological_tests.py. This allows us to include tests that we don't yet know how to pass.
Add timeout to pathological_tests.py. Tests must complete in 8 seconds or are errors.
Add more pathological tests.
Use pledge(2) on OpenBSD (Ashe Connor).
Update the Racket wrapper (Eli Barzilay).
Makefile: For afl target, don't build tests.

cmark: updated to 0.28.3

[0.28.3]
* Include GNUInstallDirs in src/CMakeLists.txt.
  This fixes build problems on some cmake versions.

[0.28.2]
* Fixed regression in install dest for static library.
  Due to a mistake, 0.28.1 installed libcmark.a into include/.

[0.28.1]
* --smart: open quote can never occur right after ] or ).
* Fix quadratic behavior in finalize (Vicent Marti).
* Don't use CMAKE_INSTALL_LIBDIR to create libcmark.pc.
  This wasn't getting set in processing libcmark.pc.in, and we
  were getting the wrong entry in libcmark.pc.
  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.
* Update README.md, replace make astyle with make format

Updated textproc/cmark 0.26.1 to 0.27.1
---------------------------------------
cmark 0.27.1
 jgm released this on 19 Nov 2016 揃 46 commits to master since this release

 -  Set policy for CMP0063 to avoid a warning (#162).
    Put set_policy under cmake version test.
    Otherwise we get errors in older versions of cmake.
 -  Use VERSION_GREATER to clean up cmake version test.
 -  Improve afl target. Use afl-clang by default. Set default for path.

cmark 0.27.0
 jgm released this on 19 Nov 2016 揃 49 commits to master since this release

 -  Update spec to 0.27.
 -  Fix warnings building with MSVC on Windows (#165, Hugh Bellamy).
 -  Fix CMAKE_C_VISIBILITY_PRESET for cmake versions greater than 1.8
    (e.g. 3.6.2) (#162, Hugh Bellamy). This lets us build swift-cmark
    on Windows, using clang-cl.
 -  Fix for non-matching entities (#161, Yuki Izumi).
 -  Modified print_delimiters (commented out) so it compiles again.
 -  make format: don't change order of includes.
    Changed logic for null/eol checks (#160).
    * 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)
 -  Fix by not advancing past both \0 and \n (Yuki Izumi).
 -  Add test for NUL-LF sequence (Yuki Izumi).
 -  Fix memory leak in list parsing (Yuki Izumi).
 -  Use cmark_mem to free where used to alloc (Yuki Izumi).

 -  Allow tabs after setext header line (jgm/commonmark.js#109).
 -  Don't let URI schemes start with spaces.
 -  Fixed h2..h6 HTML blocks (jgm/CommonMark#430). Added regression test.
 -  Autolink scheme can contain digits (Gábor Csárdi)
 -  Fix nullary function declarations in cmark.h (Nick Wellnhofer).
 -  Fixes strict prototypes warnings.
 -  COPYING: Update file name and remove duplicate section and
     (Peter Eisentraut).

Updated textproc/cmark 0.24.1 to 0.26.1
---------------------------------------
cmark 0.26.1

@jgm jgm released this Jul 16, 2016 . 18 commits to master since this release

  * Removed unnecessary typedef that caused build failure on some platforms.
  * Use $(MAKE) in Makefile instead of hardcoded make (#146, Tobias Kortkamp).

cmark 0.26.0

@jgm jgm released this Jul 15, 2016 . 23 commits to master since this release

  * Implement spec changes for list items:
      + Empty list items cannot interrupt paragraphs.
      + Ordered lists cannot interrupt paragraphs unless they start with 1.
      + Removed "two blank lines break out of a list" feature.
  * Fix sourcepos for blockquotes (#142).
  * Fix sourcepos for atx headers (#141).
  * Fix ATX headers and thematic breaks to allow tabs as well as spaces.
  * Fix chunk_set_cstr with suffix of current string (#139, Nick Wellnhofer).
    It's possible that cmark_chunk_set_cstr is called with a substring (suffix)
    of the current string. Delay freeing of the chunk content to handle this
    case correctly.
  * Export targets on installation (Jonathan M?ller). This allows using them in
    other cmake projects.
  * Fix cmake warning about CMP0048 (Jonathan M?ller).
  * commonmark renderer: Ensure we don't have a blank line before a code block
    when it's the first thing in a list item.
  * Change parsing of strong/emph in response to spec changes. process_emphasis
    now gets better results in corner cases. The change is this: when
    considering matches between an interior delimiter run (one that can open
    and can close) and another delimiter run, we require that the sum of the
    lengths of the two delimiter runs mod 3 is not 0.
  * Ported Robin Stocker's changes to link parsing in jgm/CommonMark#101. This
    uses a separate stack for brackets, instead of putting them on the
    delimiter stack. This avoids the need for looking through the delimiter
    stack for the next bracket.
  * cmark_reference_lookup: Return NULL if reference is null string.
  * Fix character type detection in commonmark.c (Nick Wellnhofer). Fixes test
    failures on Windows and undefined behavior.
      + Implement cmark_isalpha.
      + Check for ASCII character before implicit cast to char.
      + Use internal ctype functions in commonmark.c.
  * Better documentation of memory-freeing responsibilities. in cmark.h and its
    man page (#124).
  * Use library functions to insert nodes in emphasis/link processing.
    Previously we did this manually, which introduces many places where errors
    can creep in.
  * Correctly handle list marker followed only by spaces. Previously when a
    list marker was followed only by spaces, cmark expected the following
    content to be indented by the same number of spaces. But in this case we
    should treat the line just like a blank line and set list padding
    accordingly.
  * Fixed a number of issues relating to line wrapping.
      + Extend CMARK_OPT_NOBREAKS to all renderers and add --nobreaks.
      + Do not autowrap, regardless of width parameter, if CMARK_OPT_NOBREAKS
        is set.
      + Fixed CMARK_OPT_HARDBREAKS for LaTeX and man renderers.
      + Ensure that no auto-wrapping occurs if CMARK_OPT_NOBREAKS is enabled,
        or if output is CommonMark and CMARK_OPT_HARDBREAKS is enabled.
  * Set stdin to binary mode on Windows (Nick Wellnhofer, #113). This fixes
    EOLs when reading from stdin.
  * Add library option to render softbreaks as spaces (Pavlo Kapyshin). Note
    that the NOBREAKS option is HTML-only
  * renderer: no_linebreaks instead of no_wrap. We generally want this option
    to prohibit any breaking in things like headers (not just wraps, but
    softbreaks).
  * Coerce realurllen to int. This is an alternate solution for pull request #
    132, which introduced a new warning on the comparison (Benedict Cohen).
  * Remove unused variable link_text (Mathiew Duponchelle).
  * Improved safety checks in buffer (Vicent Marti).
  * Add new interface allowing specification of custom memory allocator for
    nodes (Vicent Marti). Added cmark_node_new_with_mem,
    cmark_parser_new_with_mem, cmark_mem to API.
  * Reduce storage size for nodes by using bit flags instead of separate
    booleans (Vicent Marti).
  * config: Add SSIZE_T compat for Win32 (Vicent Marti).
  * cmake: Global handler for OOM situations (Vicent Marti).
  * Add tests for memory exhaustion (Vicent Marti).
  * Document in man page and public header that one should use the same memory
    allocator for every node in a tree.
  * Fix ctypes in Python FFI calls (Nick Wellnhofer). This didn't cause
    problems so far because all types are 32-bit on 32-bit systems and
    arguments are passed in registers on x86-64. The wrong types could cause
    crashes on other platforms, though.
  * Remove spurious failures in roundtrip tests. In the commonmark writer we
    separate lists, and lists and indented code, using a dummy HTML comment. So
    in evaluating the round-trip tests, we now strip out these comments. We
    also normalize HTML to avoid issues having to do with line breaks.
  * Add 2016 to copyright (Kevin Burke).
  * Added to_commonmark in test/cmark.py (for round-trip tests).
  * spec_test.py - parameterize do_test with converter.
  * spec_tests.py: exit code is now sum of failures and errors. This ensures
    that a failing exit code will be given when there are errors, not just with
    failures.
  * Fixed round trip tests. Previously they actually ran cmark instead of the
    round-trip version, since there was a bug in setting the ROUNDTRIP variable
    (#131).
  * Added new roundtrip_tests.py. This replaces the old use of simple shell
    scripts. It is much faster, and more flexible. (We will be able to do
    custom normalization and skip certain tests.)
  * Fix tests under MinGW (Nick Wellnhofer).
  * Fix leak in api_test (Mathieu Duponchelle).
  * Makefile: have leakcheck stop on first error instead of going through all
    the formats and options and probably getting the same output.
  * Add regression tests (Nick Wellnhofer).

cmark 0.25.2

@jgm jgm released this Mar 26, 2016 . 114 commits to master since this release

  * Open files in binary mode (#113, Nick Wellnhofer). Now that cmark supports
    different line endings, files must be openend in binary mode on Windows.
  * Reset partially_consumed_tab on every new line (#114, Nick Wellnhofer).
  * Handle buffer split across a CRLF line ending (#117). Adds an internal
    field to the parser struct to keep track of last_buffer_ended_with_cr.
    Added test.

cmark 0.25.1

@jgm jgm released this Mar 25, 2016 . 122 commits to master since this release

  * Release with no code changes. cmark version was mistakenly set to 0.25.1 in
    the 0.25.0 release (#112), so this release just ensures that this will
    cause no confusion later.

cmark 0.25.0

@jgm jgm released this Mar 25, 2016 . 124 commits to master since this release

  * Fixed tabs in indentation (#101). This patch fixes S_advance_offset so that
    it doesn't gobble a tab character when advancing less than the width of a
    tab.
  * Added partially_consumed_tab to parser. This keeps track of when we have
    gotten partway through a tab when consuming initial indentation.
  * Simplified add_line (only need parser parameter).
  * Properly handle partially consumed tab. E.g. in

    - foo

     <TAB><TAB>bar

    we should consume two spaces from the second tab, including two spaces
    in the code block.

  * Properly handle tabs with blockquotes and fenced blocks.
  * Fixed handling of tabs in lists.
  * Clarified logic in S_advance_offset.
  * Use an assertion to check for in-range html_block_type. It's a programming
    error if the type is out of range.
  * Refactored S_processLines to make the logic easier to understand, and added
    documentation (Mathieu Duponchelle).
  * Removed unnecessary check for empty string_content.
  * Factored out contains_inlines.
  * Moved the cmake minimum version to top line of CMakeLists.txt (tinysun212).
  * Fix ctype(3) usage on NetBSD (Kamil Rytarowski). We need to cast value
    passed to isspace(3) to unsigned char to explicitly prevent possibly
    undefined behavior.
  * Compile in plain C mode with MSVC 12.0 or newer (Nick Wellnhofer). Under
    MSVC, we used to compile in C++ mode to get some C99 features like mixing
    declarations and code. With newer MSVC versions, it's possible to build in
    plain C mode.
  * Switched from "inline" to "CMARK_INLINE" (Nick Wellnhofer). Newer MSVC
    versions support enough of C99 to be able to compile cmark in plain C mode.
    Only the "inline" keyword is still unsupported. We have to use "__inline"
    instead.
  * Added include guards to config.h
  * config.h.in - added compatibility snprintf, vsnprintf for MSVC.
  * Replaced sprintf with snprintf (Marco Benelli).
  * config.h: include stdio.h for _vscprintf etc.
  * Include starg.h when needed in config.h.
  * Removed an unnecessary C99-ism in buffer.c. This helps compiling on systems
    like luarocks that don't have all the cmake configuration goodness (thanks
    to carlmartus).
  * Don't use variable length arrays (Nick Wellnhofer). They're not supported
    by MSVC.
  * Test with multiple MSVC versions under Appveyor (Nick Wellnhofer).
  * Fix installation dir of man-pages on NetBSD (Kamil Rytarowski).
  * Fixed typo in cmark.h comments (Chris Eidhof).
  * Clarify in man page that cmark_node_free frees a node's children too.
  * Fixed documentation of --width in man page.
  * Require re2c >= 1.14.2 (#102).
  * Generated scanners.c with more recent re2c.

(pkgsrc changes)

Fix HOMEPAGE to be copy'n'pastable.

cmark can be build inside WRKSRC/build (thanks @leot)

Import cmark-0.24.1 as textproc/cmark

cmark is the C reference implementation of CommonMark, a rationalized version
of Markdown syntax with a spec.

It provides a shared library (libcmark) with functions for parsing CommonMark
documents to an abstract syntax tree (AST), manipulating the AST, and rendering
the document to HTML, groff man, LaTeX, CommonMark, or an XML representation of
the AST. It also provides a command-line program (cmark) for parsing and
rendering CommonMark documents.
