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.
|
|
Fixes jgm/pandoc#5033.
|
|
|
|
This is needed for round-trip tests.

Add xml:space="preserve" in XML output when appropriate
|
|
Closes #263.
|
|
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.

These affect both parsing and writing commonmark.

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.

Added regression test.
See commonmark/CommonMark#527.

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.

To conform to recent spec change.

This fixes a recently added failing spec test case.
Previously spaces were being allowed in unquoted attribute
values; no we forbid them.

See commonmark/CommonMark#497.

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]`.

Fixes issue #247.

Fixes installation error under some CMake versions, notably kalakris'
CMake backport often used with Travis.

Due to a mistake, 0.28.1 installed libcmark.a into include/.
Closes #238.

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.

This option was added in 04726a7 (Added `CMARK_OPT_VALIDATE_UTF8`
option. - 2015-06-16) but not "documented".

Commit 14ea489f5dd6e3d07e23f104d6c9ce441d05751b

Use unsigned integer when shifting
|
|
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 |
```
|
|
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.
|
|
This also brings the code into closer alignment with the wording
of the spec.
See jgm/CommonMark#467.

We got an array overflow in enumerated lists nested more than
10 deep with start number =/= 1.
Found by google/oss-fuzz.

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

This can be run locally with `make libFuzzer` but the harness will be
integrated into oss-fuzz for large-scale fuzzing.
