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.

shows two unsightly errors, apparently triggered by TERM=unknown:
tput: unknown terminal "unknown"
/build/buildd/elinks-0.12~pre5/configure: line 25480: test: -ge: unary operator expected
Hide the first of them by redirecting to /dev/null,
and avoid the second one by substituting "0" if tput fails.
I'm not sure why `which tput` is used instead of plain tput,
but it doesn't seem to be causing any problems in practice.
(There are problems in theory if tput is not installed,
tput is found in a directory whose name contains spaces,
or tput is a shell function or builtin.)

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.

This reverts commit d06cccffd6.
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.
Before this change, exec_later allocates memory for the struct exec_mailcap
structure using calloc. However, the memory is freed in
exec_mailcap_command using mem_free. Change exec_later to use mem_calloc
instead of calloc.
Unless CONFIG_FASTMEM is used, mem_free expects to find debugging metadata
that only the mem_alloc family of functions store, and thus using mem_free
on the memory allocated using calloc causes a crash.
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.
Add session_class, which defines a JSObject wrapper for struct session.
Add location_array_class, which defines a JSObject wrapper for struct
ses_history. The "history" member of struct session is a struct
ses_history, which is a linked list of struct location.
Add a pointer from struct session to the session_class object and the
location_array object.
Add smjs_get_session_object to return a session_class JSObject wrapper for
a given struct session.
Add smjs_get_session_location_array_object to return a location_array_class
JSObject wrapper for a given struct session.
Add "session" property to the "elinks" object, which uses
smjs_get_session_object to get a JSObject wrapper for smjs_ses.
Add smjs_location_array_get_property, which allows indexing
a location_array object using a positive number for history forward or
a negative number for history backward.
Add session_props, session_get_property, session_set_property,
session_funcs, smjs_session_goto_url (which implements the "goto" method),
and smjs_init_session_interface for session_class.
Add session_construct, which creates a new tab and returns the JSObject
session_class wrapper.
Add session_finalize and smjs_location_array_finalize, which clear the
pointers between struct session and the JSObject wrappers in question.
Add smjs_detach_session_object, which clears the pointers between a given
struct session and the corresponding JSObject wrappers.
In destroy_session, call smjs_detach_session_object.
Add jsval_to_object helper in ecmascript/spidermonkey/util.h;
jsval_to_object is used in smjs_session_goto_url.
Modify delayed_goto_uri_frame to allow the target to be NULL.
smjs_session_goto_url needs this modification.
Currently, it is possible for the JSObject that wraps a struct view_state
to outlive the view_state. Using the properties of the JSObject wrapper
will then cause a crash.
This patch adds a smjs_detach_view_state_object function, which is called
in destroy_vs, to dissociate the struct view_state from the JSObject
wrapper. To this end, the patch modifies the struct view_state to point
the JSObject wrapper. smjs_get_view_state_object will use this pointer
if it is set, and copy_vs will copy this pointer to the new view_state.
The patch also modifies view_state_get_property and
view_state_set_property to return immediately if the view_state has been
destroyed. Finally, the patch adds a finalizer (view_state_finalize)
that clears the pointer from the struct view_state to the JSObject.
After recent simplifications, the jsobj variable is no longer necessary.
Instead of assigning it a value and then returning it, just return the
value that was being assigned to it.
Add elinks_get_property and elinks_set_property functions and
a JSPropertySpec elinks_props table to handle properties rather than
defining eilnks_get_home, elinks_get_location, and elinks_set_location
and adding them individually to the class using JS_DefineProperty.
This approach will make it easier to add further properties.
Currently, elinks_alert assumes that smjs_ses is not NULL and crashes if
it is. Change elinks_alert to check whether smjs_term is NULL, try
get_default_terminal if so, and fall back on printing to stderr using
usrerror if no terminal is found.
In smjs_load_uri, check whether the the given URI string is empty. If it
is, return JS_FALSE right away rather than continuing on and passing
get_uri an empty string, which triggers an assertion failure later on.
read_http_post_inline decodes two hexadecimal digits into one byte at
a time, and it asserts that each hexadecimal digit is valid; however,
both assertions print the first digit when they fail. Fix the assertion
on the second digit to print the second digit.
Currently, the function try_form_insert_mode checks whether the current
link is a text area, insert mode is off, and the current action is enter,
and if so, it sets insert mode on. Perform this work in enter instead,
and delete try_form_insert_mode.
The old code works as follows: send_kbd_event → send_to_frame
→ frame_ev → frame_ev_kbd → try_form_insert_mode. The new code works
as follows: send_kbd_event → do_action → enter.
Currently, using smjs_load_uri on javascript: URIs cause an assertion
failure in run_connection because smjs_load_uri uses
get_protocol_handler to find the handler and asserts that the returned
handler is not NULL, but get_protocol_handler returns NULL for
javascript: URIs.
In smjs_load_uri, if the given URI has a protocol for which some
external handler is defined, immediately return JS_FALSE because
smjs_load_uri implements an asynchronous operation, and we cannot
reasonably carry out the operation and callback with an external
handler.
