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.
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
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.

I was trying to check which charset WIDGET_TEXT uses in the buffer but
had difficulty finding the code that handles key presses and updates
the buffer. These comments should make that easier in the future.
text_typeahead_handler: Document that passing -2 for action_id will cause
a search without error reporting. This behaviour is unintentionally the
current behaviour of text_typeahead_handler, but now it is documented so
that it can be used.
input_line_event_handler: When rewinding, pass -2 for the action_id
parameter to the handler instead of passing again whatever action led to
the rewinding.
The old behavior of input_line_event_handler was particularly problematic
with the search-toggle-regex action and the text_typeahead_handler handler:
input_line_event_handler would call the handler with
ACT_EDIT_SEARCH_TOGGLE_REGEX, and the handler would toggle the setting and
perform the search again; then if the search string no longer matched
anything, the handler would return INPUT_LINE_REWIND to
input_line_event_handler, which would rewind and call the handler with
ACT_EDIT_SEARCH_TOGGLE_REGEX again, thus toggling the option back to the
original setting.
With the new behaviour, input_line_event_handler will not repeat the same
action when re-invoking the handler; in the above example with
search-toggle-regex, the search string will simply be rewound until it
matches with the new setting.
Hierarchical listboxes draw items with upper-left corner, lower-left
corner, or horizontal border characters to indicate whether a given item is
the first item in a listbox, the last, or any other, respectively.
However, the wrong character can be drawn if there are invisible items: if
an item is the first (or last) visible item but there is an invisible item
before (or after) it, it will be drawn with a horizontal border character,
not a corner.
This patch fixes that problem using traverse_listbox_items_list in
display_listbox_item to ignore invisible items when determining whether
an item is either the first or the last among its siblings.
Drop special handling of ctrl-l in handle_interlink_event.
To make sure that the 'redraw' action works everywhere, first modify
menu_kbd_handler and mainmenu_kbd_handler to handle ACT_MENU_REDRAW; and
second, drop the ACTION_REQUIRE_VIEW_STATE flag from the 'redraw' action in
the 'main' keymap so that it works even if there is no document loaded.
Ctrl-l is already bound to 'redraw' in all keymaps by default, so the
current default behaviour is preserved.

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.
This simplifies the callers a little and may help implement
simultaneous support for different charsets on different terminals
of the same type (bug 1064).
Merge functions:
redraw_from_window(win) => redraw_windows(REDRAW_IN_FRONT_OF_WINDOW, win)
redraw_below_window(win) => redraw_windows(REDRAW_BEHIND_WINDOW, win)
Add REDRAW_WINDOW_AND_FRONT as a third possibility.
Then use that in update_hierbox_browser(), which previously used
window.next for this purpose, and in dialog-scrolling code,
which previously did not redraw the dialog box itself.
Add new routine compute_redraw_interval, which returns the appropriate
interval in milliseconds for updating the LED panel, namely 100ms if there
are any downloads, 1000 if the clock is enabled (with a TODO noted to check
whether the date format includes seconds), or 0 otherwise to indicate that
the LED paanel need not be updated
Use the new compute_redraw_interval routine in draw_leds and redraw_leds.
This fixes bug 973, "LED indicators wake system up every 100ms".
