* Support the <slot> tag
<slot> was added to the WHATWG HTML5 Living Standard on April 20, 2016.
* Also support the slot= attribute
Given that the <slot> tag by itself is not too useful, this commit also
introduces support for the global slot attribute.
* Using ParseBlock for <slot>
This is still suboptimal since ParseBlock will make it so that <slot>
always expects "Flow content", whereas the spec says that it should
have a Transparent content model.
In practice, it should allow all the cases that the spec allows for, but
it will also allow some cases that the spec does not allow. Notably, if
a <slot> tag is found in a Phrasing content (an inline context in
libtidy lingo), it will wrongly let Flow content (block tags in libtidy
lingo), whereas it shouldn't. But all in all, it's a good compromise.
- Added doxygen documentation to `tags.h`
- Consistency to `tags.c` header.
- Moved TY_(DeclareUserTag) to tags.c/.h for consistency with the other list
parsing declaratory functions.
- Merged user tags parsing into the general list, eliminating a lot of redundant
code.
According to the MSN documentation 'isalnum(c)' is only valid when c equals
EOF, or is in the range 0 to 255 inclusive. It states the behavior is
undefined outside this range, and in Debug mode triggers an assert dialog.
in #352, but I'm worried that there's some over-reach here.
Currently only implemented as a warning, with no switch to turn it off, which
maintains current behavior other than the warning.
In general, we're treating any string as a complete URL, rather than breaking
URL's into component parts. Thus the `IsURLCodePoint()` check includes a few
other generic characters that strictly speaking aren't valid codepoints, but
are valid as escape characters and delimiters.
When addressing #338, I ran into a similar situation in not having a built-in
method to separate path components (although a simple generalized solution was
good enough in that case).
Thus without introducing a new structure and functions to deconstruct a URL
into scheme, authority, path, parameters, etc., some variation of this patch
will have to be used to address #352.
This is a MUCH SANER approach to what I was trying to do (now that I screwed up enough internals to understand some of them!
At this point there are zero exit state reversions, and zero markup reversions! There are still 21 errout reversions; I'll
annotate and adjust as necessary.
my changes, I'm starting over with this. Comments in the PR thread.
This commit reduces the size of attrdict.c while causing only a single errout
regression that is justified.
An immense thanks to Ger Hobbelt who had already done this
in his github.com/GerHobbelt/htmltidy fork.
The two sources have diverges so was not a simple cut
an paste. But again thanks Ger for this.
