In the previous version, invalid UTF-8 from a terminal caused
UCS_NO_CHAR (0xFFFFFFFD) to be stored in a term_event_key_T, resulting
in -3 which was then incidentally treated as an unassigned special key.
Now, invalid UTF-8 is instead mapped to UCS_REPLACEMENT_CHARACTER
and treated as a character. The fact that handle_interlink_event
calls term_send_ucs when it receives invalid UTF-8 makes it pretty
clear that this is how it was intended.
src/viewer/text/link.c (not changed in this commit) already referred
to UCS_REPLACEMENT_CHARACTER in a comment even though it was not
previously defined.
The message appears when the user has selected e.g. "Main mapping"
rather than an action inside it. Because the main mapping is a keymap,
ELinks must not tell the user to select a keymap.
whether we ought to add the conn->progress->start to
the conn->est_length. Currently displaying resuming works correctly with
ftp.task.gda.pl and ftp.pld-linux.org.
Restring the spaghetti in dump_to_file to fix a bug that was introduced
in commit 2a6125e3d0 whereby when
document.dump.codepage != "utf-8", the document itself was not output,
only the references list.
Decrement term->current_tab before calling delete_window() instead of after
deleting all backgrounded tabs, so get_tab_by_number() will see a
consistent value.
It cannot be restricted just to characters that have passed
check_kbd_label_key(), because hotkeys in strings received from
gettext must also be processed with it, and there we don't have
a struct term_event for check_kbd_label_key().
This causes the documented-slow cp2u() to be called in a loop, which
fortunately doesn't have very many iterations. If this is too slow,
then cp2u() can be rewritten, or the hotkeys can be cached in struct
widget or struct widget_data.
Note that check_kbd_label_key() does not yet allow non-ASCII
characters when CONFIG_UTF_8 is defined. Before they are allowed,
menu.c should also be updated.
According to Jonas Fonseca, if init_string(&canonical) fails, then it
anyway sets canonical.source = NULL and makes done_string(&canonical)
safe, even if canonical was previously uninitialized.
Actions can now be bound to e.g. Ctrl-Alt-A. The keybinding code also
supports other combinations of modifiers, like Shift-Ctrl-Up, but the
escape sequence decoder doesn't yet.
Don't let Ctrl-Alt-letter combinations open menus.
The cast is not necessary since we already check the bounds, but by using a
cast here, it hopefully makes it more obvious what the long comment above
is pointing out: namely that we put the value of a signed integer into an
unsigned char.
This fixes a bug: in the previous version, l_bind_key() modified the
buffer whose address lua_tostring() returned, even though that is not
allowed according to Lua documentation <http://www.lua.org/pil/24.2.2.html>.
The change affects the user interface: previously, if the user typed
"ctrl+cokebottle" in the "Add keybinding" dialog box, ELinks would
change the text in the widget to "Ctrl-cokebottle" before complaining
that the keystroke is invalid. Now, it leaves the widget unchanged.
This commit does not yet add const to parameters of parse_keystroke()
and related functions.
