There is no good way to inform slave elinks instances about options. So, for mouse there is a workaround.
Note, If you set ui.mouse_disable = 1 in elinks.conf manually, to get effect on 2nd ELinks instance,
you must also touch ~/.elinks/mouse.lock . Changes via option manager delete or create this file automatically.
The solution with fork() is more general, but it unnecessarily produces two new
process: one in exe_no_stdin(), one in system(). The solution with FD_CLOEXEC
is simpler as it only requires changing and restoring a flag of stdin, but I
suspect it may not be available in all OSes elinks can be compiled for.
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
Call get_window_title() at most once per terminal, even if it fails.
If ELinks is configured with X11 support, get_window_title() calls
XOpenDisplay(), which can sleep if $DISPLAY does not respond.
This delay was previously incurred every time ELinks changed the
title. Besides, if ELinks had already changed the title, setting
ditrm->orig_title = get_window_title(); did not make sense anyway.

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 terminal_class, which defines a JSObject wrapper for struct terminal.
Add terminal_array_class, which defines a JSObject wrapper for accessing
the "terminals" linked list of struct terminal.
Add session_array_class, which defines a JSObject wrapper for accessing the
tabs (sessions) of a terminal.
Add pointers from struct terminal to the terminal_class object and
the session_array_class object.
Add terminal_props and terminal_get_property for terminal_class.
Add terminal_finalize, which clears the pointers between a struct terminal
and the JSObject wrapper in question.
Add smjs_init_terminal_interface, which creates a terminal_array_class
instance and assigns it to the "terminal" property on the "elinks" object.
Call smjs_init_terminal_interface from smjs_init_elinks_object.
Add smjs_get_terminal_object and smjs_get_session_array_object to get
the wrapper objects for a given struct terminal, and add
smjs_get_terminal_array_object to get a terminal_array_class object.
Add smjs_detach_terminal_object and smjs_detach_session_array_object, which
clear the pointers between a given struct terminal and its JSObject
wrappers.
Add terminal_array_get_property for terminal_array_class.
Add session_array_get_property for session_array_class.
gnome-terminal 2.30.2 expects UTF-8 in the "OSC Ps ; Pt BEL" sequence
that sets the window title. However, XGetWMName typically returns the
title in "STRING" (Latin-1) or "COMPOUND_TEXT" (escape sequences)
encoding. Recode the title to restore it correctly. This helps
especially in the fi_FI.UTF-8 locale, where gnome-terminal has "Pääte"
as the default title.
Related to bugs 885 and 336.
With document.browse.accesskey.priority = 0, accesskeys were ignored if
the current tab was not the last (rightmost) tab. This commit fixes the
problem.
Add a function tabs_are_on_top(struct terminal *) which returns
a Boolean value indicating whether the topmost window is a tab (as
opposed to, e.g., a menu).
This commit fixes commit 1bd498cde9.
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.
Add 'Italic' checkbox to Terminal options dialog box.
Enable italic text by default for rxvt-unicode (and also enable
frames, 88-colour mode, and underline).
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.
When ELinks runs in an X11 terminal emulator (e.g. xterm), or in GNU
Screen, it tries to update the title of the window to match the title
of the current document. To do this, ELinks sends an "OSC 1 ; Pt BEL"
sequence to the terminal. Unfortunately, xterm expects the Pt string
to be in the ISO-8859-1 charset, making it impossible to display e.g.
Cyrillic characters. In xterm patch #210 (2006-03-12) however, there
is a menu item and a resource that can make xterm take the Pt string
in UTF-8 instead, allowing characters from all around the world.
The downside is that ELinks apparently cannot ask xterm whether the
setting is on or off; so add a terminal._template_.latin1_title option
to ELinks and let the user edit that instead.
Complete list of changes:
- Add the terminal._template_.latin1_title option. But do not add
that to the terminal options window because it's already rather
crowded there.
- In set_window_title(), take a new codepage argument. Use it to
decode the title into Unicode characters, and remove only actual
control characters. For example, CP437 has graphical characters in
the 0x80...0x9F range, so don't remove those, even though ISO-8859-1
has control characters in the same range. Likewise, don't
misinterpret single bytes of UTF-8 characters as control characters.
- In set_window_title(), do not truncate the title to the width of the
window. The font is likely to be different and proportional anyway.
But do truncate before 1024 bytes, an xterm limit.
- In struct itrm, add a title_codepage member to remember which
charset the master said it was going to use in the terminal window
title. Initialize title_codepage in handle_trm(), update it in
dispatch_special() if the master sends the new request
TERM_FN_TITLE_CODEPAGE, and use it in most set_window_title() calls;
but not in the one that sets $TERM as the title, because that string
was not received from the master and should consist of ASCII
characters only.
- In set_terminal_title(), convert the caller-provided title to
ISO-8859-1 or UTF-8 if appropriate, and report the codepage to the
slave with the new TERM_FN_TITLE_CODEPAGE request. The conversion
can run out of memory, so return a success/error flag, rather than
void. In display_window_title(), check this result and don't update
caches on error.
- Add a NEWS entry for all of this.
This simplifies the callers a little and may help implement
simultaneous support for different charsets on different terminals
of the same type (bug 1064).
Except if they have external handlers.
When ELinks receives an event from a terminal, move that terminal to
the beginning of the global "terminals" list, so that the terminals
are always sorted according to the time of the most recent use. Note,
this affects the numbering of bookmark folders in session snapshots.
Add get_default_terminal(), which returns the most recently used
terminal that is still open. Use that in various places that
previously used terminals.prev or terminals.next. Four functions
fetch the size of the terminal for User-Agent headers, and
get_default_terminal() is not really right, but neither was the
original code; add TODO comments in those functions.
When the user chooses "Background and Notify", associate the download
with the terminal where the dialog box is. So any later messages will
then appear in that terminal, if it is still open. However, don't
change the terminal if the download has an external handler.
When a download gets some data, don't immediately check the associated
terminal. Instead, wait for the download to end. Then, if the
terminal of the download has been closed, use get_default_terminal()
instead. If there is no default terminal either, just skip any
message boxes.
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.
ELinks attempted to display a message box on file_download.term, but
it had already closed that terminal and freed the struct terminal. To
fix this, reset file_download.term pointers to NULL when the terminal
is about to be destroyed. Also, assert in download_data_store() that
file_download.term is either NULL or in the global "terminals" list.

(cherry picked from commit 6e2476ea4d)
This patch prevents handle_itrm_stdin() and clear_handlers(itrm->in.std) to be
called when -remote is set and in.std < 0.
It adds two assertions for in.std >= 0 in handle_itrm_stdin() and
unhandle_itrm_stdin().
May be a bad fix, please test and review.
[Added a NEWS entry. --KON]
When setting the tty device to raw mode, save the VERASE character.
Later, compare incoming bytes to that.
This is somewhat complicated because "stty verase undef"
sets termios.c_cc[VERASE] = _POSIX_VDISABLE, and e.g. Linux
defines _POSIX_VDISABLE as 0 but that must not cause ELinks
to treat incoming null bytes as backspaces. Furthermore,
some systems may use different VDISABLE values for different
terminal devices, in which case _POSIX_VDISABLE is undefined
and ELinks must instead read the value from fpathconf().
When returning from an external program, unblock_itrm_x in the slave process will send a resize event to the master process for the slave terminal. In handle_interlink_event, when we receive this resize event, we can check whether we need to call textarea_edit.
