Option document.browse.preferred_document_width controls the
width of the document, so that documents are rendered with narrower
width than screen width. Makes it easier to read paragraphs.
Patch originally from Shalon Wood <dstar@pele.cx>, see bug #1063.
Instead of using max_document_width as the hard limit to the document
width, it uses a soft limit, where if the document does not fit (due to
tables, etc.), then larger width is used. This reduces the need for
horizontal scrolling for wide documents.
Also added toggle-document-width action to toggle between preferred
width and full screen width. This is bound to 'M' by default. Initial
toggle status is determined by document.browse.use_preferred_document_width
option.
During dumps, document.dump.width option is still used. Perhaps we
should consolidate document.dump.width option with
document.browse.preferred_document_width ?
These settings are specified by
document.colors.link_number
document.colors.use_link_number_color
The latter setting determines whether the color is used when document
colors are being used.
See bug #1050.
If there are isolated combining characters, e.g. at the beginning of a paragraph
or table cell:
– if it’s not the first screen column, combine them with whatever character is
printed to their left;
– otherwise, add a no-break space as the base character.
Previously, such combining characters were combined with the last letter
displayed, i.e. the last letter of the previous paragraph or cell.

without waiting for the next non zero width character. This way combining
characters at the end of the document are displayed.

Otherwise, there are unnecessary spaces at the end of lines in tables containing
combining characters.

A combining character sequence where the base character is a space remained
recorded as a space although the initial space was replaced with an internal
code corresponding to the combined character. This caused an internal error when
ELinks tried to split the line at that place and did not find the space.

* Rename P_STAR as P_DISC and P_PLUS as P_SQUARE.
* Delete P_NONE because it was used only as the default flag in init_html_parser
and a list with P_NONE then got bullets, so instead use P_DISC by default (as
per the CSS specification), and P_NO_BULLET for lists with no bullets.
* Use as bullets the characters:
- U+25E6 WHITE BULLET for the circle style;
- U+25AA BLACK SMALL SQUARE (alias square bullet) for the square style;
- U+2022 BULLET for the disc style (default).

Some people wants URL in the title bar, but some wants the title.
I restored previous version (the title). If you want the URL, create
the patch with a configurable option.
Recognise the list-style property and apply it by setting the
appropriate flag on the element's parattr based on the property's value.
Add test/list-style.html with an example of each possible list-style
value (many are unsupported by the HTML engine).
The URL in <meta http-equiv="Refresh" content="42; URL=target.html">
can now freely contain spaces and semicolons. There cannot be other
parameters between the delay and the URL. If the URL is not quoted,
then it spans to the end of the attribute, except not to trailing
spaces. If the URL is quoted, then it ends at the first closing
quotation mark. All this is consistent with Debian Iceweasel 3.5.16.
The HTML parser decoded SGML entity references and numeric character
references in the following attributes, and then the renderer did the
same again:
link/@title
link/@hreflang
link/@type
link/@media
img/@alt
area/@alt
input[@type="image"]/@alt
input[@type="image"]/@name
input[@type="button"]/@value
The result was that e.g. title="&#65;" displayed as "A"
even though it was supposed to display as "A".
Fix by making the HTML parser tell the renderer that the entities have
already been decoded.
look_for_link() used to return 0 both when it found the closing </MAP>
tag, and when it hit the end of the file. In the first case, it also
added *menu to the memory_list; in the second case, it did not. The
caller get_image_map() supposedly distinguished between these cases by
checking whether pos >= eof, and freed *menu separately if so.
However, if the </MAP> was at the very end of the HTML file, so that
not even a newline followed it, then look_for_link() left pos == eof
even though it had found the </MAP> and added *menu to the memory_list.
This made get_image_map() misinterpret the result and mem_free(*menu)
even though *menu had already been freed as part of the memory_list;
thus the crash.
To fix this, make look_for_link() return -1 instead of 0 if it hits
EOF without finding the </MAP>. Then make get_image_map() check the
return value instead of comparing pos to eof. And add a test case,
although not an automated one.
Alternatively, look_for_link() could have been changed to decrement
pos between finding the </MAP> and returning 0. Then, the pos >= eof
comparison in get_image_map() would have been false. That scheme
would however have been a bit more difficult to understand and
maintain, I think.

(cherry picked from commit a2404407ce)
This patch fixes an issue whereby a newline character appearing within
a hidden input field is incorrectly reinterpreted as a space character.
The patch handles almost all cases, and includes a test case.
15/18 tests pass, but the remainder currently fail due to the fact
that ELinks does not currently support textarea scripting.
On 2008-09-05, it was reported to elinks-dev that ELinks hits an
internal error (bad alloc_header) when given a specific HTML file.
On 2008-09-09, out-of-range values of document->comb_x and
document->comb_y were noted as the cause of memory corruption.
Update those variables when splitting, aligning, or justifying a line.
Add many assertions to detect the bug if it occurs again.
Previously, the character at (document.comb_x, document.comb_y) was
accessed via the POS macro, which adds part.box.x and part.box.y to
the coordinates. However, if document.comb and document.y are set
at the end of one part and read at the beginning of another, then
the struct screen_char used by the original part should be updated,
even though the new part has a different box. Change comb_{x,y} to
be relative to the document, rather than to the box of a single part.
In document.forms, each struct form has form_num and form_end members
that reserve a subrange of [0, INT_MAX] to that form. Previously,
multiple forms in the list could have form_end == INT_MAX and thus
overlap each other. Prevent that by adjusting form_end of each form
newly added to the list.
Revert 438f039bda,
"check_html_form_hierarchy: Old code was buggy.", which made
check_html_form_hierarchy attach controls to the wrong forms.
Instead, construct the dummy form ("for those Flying Dutchmans") at
form_num == 0 always before adding any real forms to the list.
This prevents the assertion failure by ensuring that every possible
form_control.position is covered by some form, if there are any forms.
Add a function assert_forms_list_ok, which checks that the set of
forms actually covers the [0, INT_MAX] range without overlapping,
as intended. Call that from check_html_form_hierarchy to detect
any corruption.
I have tested this code (before any cherry-picking) with:
- bug 613 attachment 210: didn't crash
- bug 714 attachment 471: didn't crash
- bug 961 attachment 382: didn't crash
- bug 698 attachment 239: all the submit buttons showed the right URLs
- bug 698 attachment 470: the submit button showed the right URL

The previous code displayed the wrong attributes if the combining
characters were at the end of an HTML link. For example:
<a href="#">trickỹ</a> more text <a href="#">second link</a>
(The characters in the first A element are "tricky" and U+0303
COMBINING TILDE.)
Here, when the cursor was not at the first link, ELinks displayed
the y-with-tilde cell as if it were not part of the link.
This happened because ELinks had already changed schar->attr
before set_line saw the space character after the link and
flushed document->combi[].
Combining characters requires a UTF-8 locale.
It slows down rendering. There is still the unresolved issue with
combining characters at the end of a document.
This patch wasn't heavilly tested. Especially a "garbage" input may cause
unpredictable results.
This patch adds support for:
- option document.css.media
- CSS @import "foo.css" tty;
- CSS @media tty { ... }
- HTML <link rel="stylesheet" media="tty">
- HTML <style media="tty">
This patch is attachments 395 and 396 from bugzilla.elinks.cz, which
are based on attachment 388 from bugzilla.elinks.cz. This new
version of the patch fixes conflicts with recent 0.13.GIT changes,
marks Doxygen commands with at-signs rather than backslashes, and
adds a few comments.
This necessitates that non-pairable elements be briefly pushed on the stack, so that get_css_selector_for_element sees them, and then popped.
It would be possible to push them only when CONFIG_CSS is defined, as they are otherwise not needed (as evidenced by the fact that we've gone so long without bothering to push them). However, the performance hit should be small, the necessary #ifdef/#endif wrappers would be pretty ugly, and ideally, the CSS code will someday be in such a state that it can be considered an integral feature.
Before, *_html_parser_state() operated with struct html_element *. Now, it is
transparent for the renderer (just void *), so that DOM won't have to provide
this struct but will be able to use something internal.
Backported from master.
