SpiderMonkey was updated to mozjs24. If you want to build elinks
with ecmascript support, you must compile using g++ with -fpermissive .
There is a lot of warnings.
There are some memleaks in ecmascript code, especially related to JSAutoCompartment.
I don't know yet, where and how to free it.
Debian does not support mozjs24, so I'm going to gradually update SpiderMonkey version.
The long term goal is good looking of the Python docs in ELinks, especially
background colors. Every start tag and every text node would have associated
a natural number. Those numbers would be "drawn" in the document instead
of colors. Finally, the screen driver would change numbers into colors.
This will be done in small steps. The next step is to implement this change
in the screen driver.
The old code failed to write pending spaces before changing the
background color. That seems hard to fix without duplicating code,
and ELinks pads dumped lines to the requested width in these color
modes anyway, so this commit just makes ELinks write all spaces
immediately when colors are being used.
Try the following command before and after this commit:
elinks --no-home --eval "set document.colors.use_document_colors = 2" \
--dump-color-mode 1 --dump test/color.html
In DUMP_FUNCTION_SPECIALIZED, use isscreensafe_ucs (for UTF-8) or
isscreensafe (for unibyte) to detect control characters, and replace
them with spaces. add_document_to_string already did the same.
In DUMP_FUNCTION_SPECIALIZED (used by elinks --dump), detect the
second cell of double-cell (aka fullwidth) characters by comparing to
UCS_NO_CHAR, like add_document_to_string does. Don't use
unicode_to_cell for this any more.
Also, ignore the colors and attributes of the second cell; don't
output any escape sequences for them.
This is especially useful for showing that neither dump_truecolor_utf8
nor dump_truecolor_unibyte modifies its static color[] variable and it
therefore does not matter whether those functions use the same array
or not.
With all the comments and macros needed for this, the source files
don't become much shorter, but anyway I hope they'll be easier to
maintain this way.
