The surprising .text change comes from src/config/dialogs.o.
Some of that is in get_keybinding_text(), where GCC changes the
order of basic blocks and apparently misses some optimizations.
Remove enum main_action_offset, enum edit_action_offset, and enum
menu_action_offset. It seems the original plan (in commit
174eabf1a448d3f084a318aab77805828f35c42e on 2005-05-16) was to include
the action flags in the action IDs, perhaps with something like:
ACT_##map##_##action = ACT_##map##_OFFSET_##action | flags
However, this OR operation was never implemented; each ACT_*_*
constant had the same value as the corresponding ACT_*_OFFSET_*,
and the code that looked for flags in action IDs found only zeroes.
Then on 2005-06-10, a separate action.flags member was added, and
the flag checks were corrected to read that instead. So, it seems
safe to say that the original plan has been discarded and the offset
enumerations won't be needed.
get_keymap_id returns -1 when it can't find the keymap. Because the return
type of get_keymap_id is enum keymap_id and enum keymap_id did not have any
explicit values defined, it could be unsigned, which meant that when
get_keymap_id returned -1, it was really returning a huge positive number.
This meant that when callers checker whether the return value was negative,
they were essentially performing no check at all, so they might give
get_keymap_id an invalid keymap name, get back an invalid keymap_id, and
use that invalid keymap_id.
This commit adds KEYMAP_INVALID = -1 to enum keymap_id and makes all
functions that deal with the enumeration use that symbol.
The configure script no longer recognizes "CONFIG_UTF_8=yes" lines
in custom features.conf files. They will have to be changed to
"CONFIG_UTF8=yes". This incompatibility was deemed acceptable
because no released version of ELinks supports CONFIG_UTF_8.
The --enable-utf-8 option was not renamed.
Introduce smjs_init_keybinding_interface, which creates elinks.keymaps.<map>
for <map> in "main", "edit", and "menu". elinks.keymaps.<map> is a hash
indexed by string representations of keystrokes, and can be used to get the
current action for a key and to set the action either to an internal ELinks
action or to an ECMAScript function.
