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.
Possibility to mark rectangle for clipboard.
User may bind keys to move-cursor-up, move-cursor-down, move-cursor-left,
move-cursor-right and mark-clipboard.
mark-clipboard is tristate.
First triggerred, it remembers left top corner of rectangle. Now you can move cursor.
Second time triggerred, remembers right bottom corner of rectangle.
Third time, it clears selection.
The copy-clipboard action was changed. Now if the clipboard rectangle is marked,
it copies this rectangle. If not, the current link.
Weak points:
- alignof
- js problems
Todo:
- make js work with C++ and mozjs-17
- then mozjs-24
- then mozjs-52
- then mozjs-60
- decrease number of warnings
Before only visible part of screen was searched for pattern.
Now whole document is searched, and beginings of found text
is remembered in document->search_points.
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 ?
The color is controlled by
document.browse.links.active_link.insert_mode_colors.background
document.browse.links.active_link.insert_mode_colors.text
Also avoid overloading local variable "i" in get_current_link().
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.

Use the same functions as for the list-style property since only the "type" part
of the list-style property is supported at this stage.

* 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).

INIT_OPTION used to initialize union option_value at compile time by
casting the default value to LIST_OF(struct option) *, which is the
type of the first member. On sparc64 and other big-endian systems
where sizeof(int) < sizeof(struct list_head *), this tended to leave
option->value.number as zero, thus messing up OPT_INT and OPT_BOOL
at least. OPT_LONG however tended to work right.
This would be easy to fix with C99 designated initializers,
but doc/hacking.txt says ELinks must be kept C89 compatible.
Another solution would be to make register_options() read the
value from option->value.tree (the first member), cast it back
to the right type, and write it to the appropriate member;
but that would still require somewhat dubious conversions
between integers, data pointers, and function pointers.
So here's a rather more invasive solution. Add struct option_init,
which is somewhat similar to struct option but has non-overlapping
members for different types of values, to ensure nothing is lost
in compile-time conversions. Move unsigned char *path from struct
option_info to struct option_init, and replace struct option_info
with a union that contains struct option_init and struct option.
Now, this union can be initialized with no portability problems,
and register_options() then moves the values from struct option_init
to their final places in struct option.
In my x86 ELinks build with plenty of options configured in, this
change bloated the text section by 340 bytes but compressed the data
section by 2784 bytes, presumably because union option_info is a
pointer smaller than struct option_info was.

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.
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.
Add a case for CSS_LIST_ORDINAL (and assert(0)) to the switch in
css_apply_list_style. This change should eliminate a warning from the
compiler reported by Witold that CSS_LIST_ORDINAL is not handled.
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.
After the recent ecmascript_get_interpreter change, I got an assertion
failure in render_document, which calls ecmascript_reset_state and
then asserts that it has set vs->ecmascript != NULL.
ecmascript_reset_state cannot guarantee that because there might not
even be enough free memory for mem_calloc(1, sizeof(struct
ecmascript_interpreter). So, replace the assertion in render_document
with error handling, and likewise in call_onsubmit_and_submit.
In start_document_refresh, use register_bottom_half instead of
install_timer if the timeout is 0 because install_timer asserts that it is
given a delay greater than 0.
Add a test case, test/refresh-0timeout.html. Note that
document.browse.minimum_refresh_time must be set to 0 to reproduce the
assertion failure.
C99 6.7.4p3 and 6.7.4p6 set some constraints on what can be done in
inline functions and how they can be declared. In particular, any
function declared inline must also be defined in the same translation
unit. To comply with that, remove inline specifiers from function
declarations in header files when the functions are not also defined
in those header files.
Sun Studio 11 on Solaris 9 is stricter than C99 and does not allow
references to static identifiers in extern inline functions. Make the
configure script detect this and define NONSTATIC_INLINE accordingly
in config.h. Then use that in the definitions of all non-static
inline functions.
Document the restrictions and this scheme in doc/hacking.txt.
Documentation strings of most options used to contain a "\n" at the
end of each source line. When the option manager displayed these
strings, it treated each "\n" as a hard newline. On 80x24 terminals
however, the option description window has only 60 columes available
for the text (with the default setup.h), and the hard newlines were
further apart, so the option manager wrapped the text a second time,
resulting in rather ugly output where long lones are interleaved with
short ones. This could also cause the text to take up too much
vertical space and not fit in the window.
Replace most of those hard newlines with spaces so that the option
manager (or perhaps BFU) will take care of the wrapping. At the same
time, rewrap the strings in source code so that the source lines are
at most 79 columns wide.
In some options though, there is a list of possible values and their
meanings. In those lists, if the description of one value does not
fit in one line, then continuation lines should be indented. The
option manager and BFU are not currently able to do that. So, keep
the hard newlines in those lists, but rewrap them to 60 columns so
that they are less likely to require further wrapping at runtime.
These functions now expect or return strings in UTF-8:
delete_folder_by_name (sneak in a const, too), bookmark_terminal_tabs,
open_bookmark_folder, and get_auto_save_bookmark_foldername_utf8 (new
function).
This simplifies the callers a little and may help implement
simultaneous support for different charsets on different terminals
of the same type (bug 1064).
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.

A style-sheet containing the string "url( )" with 1 or more characters of
whitespace in between the parentheses triggered an assertion failure in
scan_css_token.
scan_css_token would find the left parenthesis, find the right parenthesis,
and then scan forwards from the left parenthesis for a non-whitespace
character to find the start of the URL and backwards from the right
parenthesis to find the end of the URL. If there were whitespace and
nothing else, the start would be past the end, the routine would compute a
negative length for the URL, and then the routine would trigger an
assertion failure. Now the routine simply enforces a lower bound of length
0 for the URL.
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.
