Closes #71.
Added a test to api_test.
|
|
Currently fails.
|
|
* Added `CMARK_OPT_SAFE`. This option disables rendering of raw HTML
and potentially dangerous links.
* Added `--safe` option in command-line program.
* Updated `cmark.3` man page.
* Added `scan_dangerous_url` to scanners.
* In HTML, suppress rendering of raw HTML and potentially dangerous
links if `CMARK_OPT_SAFE`. Dangerous URLs are those that begin
with `javascript:`, `vbscript:`, `file:`, or `data:` (except for
`image/png`, `image/gif`, `image/jpeg`, or `image/webp` mime types).
* Added `api_test` for `OPT_CMARK_SAFE`.
* Rewrote `README.md` on security.

This is easier to access using ffi, since some languages, like C#
like to use only function interfaces for accessing library
functionality.
fixes #60
|
|
Also command line option `--validate-utf8`.
This option causes cmark to check for valid UTF-8,
replacing invalid sequences with the replacement
character, U+FFFD.
Reinstated api tests for utf8.
|
|
We no longer validate utf8 before parsing.
|
|
|
|
|
|
This closes #33.
|
|
|
|
|
|
Also to some non-exported functions in blocks and inlines.
|
|
Add version number and string as macros and symbols. Version numbers can
be easily compared, for example in the C preprocessor:
#include <cmark.h>
#if CMARK_VERSION < 0x020200
#error Requires libcmark 2.2.0 or higher
#endif
Storing the version in a global variable allows to check the library
version at runtime. For example:
if (CMARK_VERSION != cmark_version) {
warn("Compiled against libcmark %s, but using %s",
CMARK_VERSION_STRING, cmark_version_string);
}
The version should be updated whenever the public API is changed.

|
* Advance to the next node when calling 'cmark_iter_next', not when
calling 'cmark_iter_get_node'.
* Add 'cmark_iter_get_event_type' accessor.
* Allow deletion of nodes after an 'EXIT' event, or an 'ENTER' event for
leaf nodes.
|
|
|
|
To keep the API simple and avoid API changes when new options are
added, this is just a long integer.
Set it by disjoining options that are defined as powers of 2: e.g.
`CMARK_HTML_SOURCEPOS | CMARK_HTML_HARDREAKS`.
Test options using `&`: `if (options & CMARK_HTML_SOURCEPOS)`.
Added `--hardbreaks` and `--sourcepos` command-line options.
|
|
Even though this doesn't make a difference in default HTML
output, it's worth keeping track; some output formats may allow
you to distinguish lists with `1)` and with `1.` delimiters.
|
|
|
|
|
|
|
|
* Added `iterator.c`, `iterator.h`.
* Removed `cmark_walk`.
* Replaced `cmark_walk` with iterator in HTML renderer.
* Replaced API test for `cmark_walk` with simple iterator test.
|
|
Added cmark_event_type enum, which is used as the second
parameter of the handler passed to cmark_walk.
See #224.
|
|
Modified finalize in blocks.c to return parent of finalized
block, so we can handle the case of reference definitions,
when we simply remove the finalized block.
|
|
This reverts commit b598b52a4acdc2332be3d34e30237d1b93b7dd03.
The change led to some problems, because some of the callers
of 'finalize' expected the node to exist after the call.
This could all be rewritten, but for now let's just revert.
|
|
There's no reason to store these empty nodes in the API.
The references have already been resolved.

cmark_doc_parser => cmark_parser
cmark_new_doc_parser => cmark_parser_new
cmark_free_doc_parser => cmark_parser_free
cmark_finish => cmark_parser_finish
cmark_process_line => cmark_parser_process_line
cmark_node_destroy => cmark_node_free
Closes #223.

|
|
This can be changed if support for node lists is added to the public API.
|
|
In JS, use 'Text' instead of 'Str'.
In spec, use "plain textual content" instead of "strings."
|
|
Windows fixes
|
|
|
|
Also disable some warnings.
|
|
Invalid UTF-8 byte sequences are replaced with the Unicode replacement
character U+FFFD. Fixes #213.
|
|
Use a single CMARK_NODE_CODE_BLOCK tag for both.
Distinguish them when needed for parsing by looking at the
fence_length attribute, which is 0 for indented blocks.
|
|
This reverts commit 4570eb2bff2e1b71fa5b6408abbc69c98ff5ff24.

This reverts commit a71423f6ee1b77d9f79d42599ea00b4ca99f5da0.
Not quite sure about this change, so reverting for now.
Note that we still have a distinction between fenced and
indented code blocks in the AST. These two distinctions
seem to stand or fall together.
|
|
Now we just have 'header' -- Setext and ATX are just two ways
of forming these; it's not a semantic difference that should remain
in the AST.
|
|
|
|
|
|
|
|
|
|
Now that every node has a parent pointer, it's possible to implement
the HTML rendering functions without render stacks and any dynamic
memory allocations.
This commit also adds some minor optimizations that eliminate some
strbuf_put* calls for the common case and avoid printf for headers.
