With Autoconf 2.60a, the default values of datadir, infodir, and
mandir refer to ${datarootdir}. If Makefile.config.in does not define
datarootdir, Autoconf detects this and expands ${datarootdir} when it
substitutes expressions like @datadir@, but it also outputs the
following warning:
config.status: creating Makefile.config
config.status: WARNING: /home/Kalle/src/elinks/Makefile.config.in seems to ignore the --datarootdir setting
According to a comment in config.status, "This hack should be removed
a few years after 2.60." So it seems best to prepare for that now by
defining datarootdir = @datarootdir@ in Makefile.config.in. Earlier
versions of Autoconf may leave that line unexpanded; but because the
makefiles do not directly refer to ${datarootdir}, there's no harm.
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.
Suggested by Miciah on #elinks.
What was renamed:
add_utf_8 => add_utf8
cp2utf_8 => cp2utf8
encode_utf_8 => encode_utf8
get_translation_table_to_utf_8 => get_translation_table_to_utf8
goto invalid_utf_8_start_byte => goto invalid_utf8_start_byte
goto utf_8 => goto utf8
goto utf_8_select => goto utf8_select
terminal_interlink.utf_8 => terminal_interlink.utf8
utf_8_to_unicode => utf8_to_unicode
What was not renamed:
terminal._template_.utf_8_io option, TERM_OPT_UTF_8_IO
Compatibility with existing elinks.conf files would require an alias.
--enable-utf-8
Because the name of the charset is UTF-8, --enable-utf-8 looks better
than --enable-utf8.
CONFIG_UTF_8
Will be renamed in a later commit.
Unicode/utf_8.cp, table_utf_8, aliases_utf_8
Will be renamed in a later commit.
Previously, the window sizes computed for xterm were a few pixels off,
and this could result in too few character cells being displayed.
This new version tries to read the window size increment from the
WM_NORMAL_HINTS property set by xterm, and base the computations on
that.
Previously, utf8_step_forward() and utf8_step_backward() left *count
unchanged if some parameter was invalid. Now, they properly store 0.
This flaw had no effect in practice, because all current callers pass
count=NULL, and invalid parameters shouldn't be used anyway.
form_state.state_cell is no longer used for FC_TEXT, FC_PASSWORD, nor FC_FILE.
Instead, get_link_cursor_offset() computes the cell with utf8_ptr2chars
(a new function) or utf8_ptr2cells. This shouldn't slow down ELinks too
much, as it's done only for the selected link and only once per redraw.
The left side of a scrolled input field is always aligned at a
character boundary. The right side might not be.
The new comments describe how the members were apparently intended to
be used. However, the implementation does not actually work when
CONFIG_UTF_8 is defined, and the current semantics do not even allow
an efficient implementation of long (mostly scrolled out) strings.
Surrogates are now treated the same way as out-of-range characters
like U+110000; if a link has such an access key, then the ECMAScript
accessKey property cannot be read. It seems currently impossible to
set such an access key though, because accesskey_string_to_unicode()
doesn't support multibyte characters yet.

Also add an empty line above the label in init_tab; but there are
still several labels elsewhere that don't have empty lines above them.
The previous scheme incorrectly accepted 0xC1 0x80 as U+0040.
That could have been fixed by tweaking the loop, but the constant
array is surely easier to verify.
- Include arpa/inet.h to get hton* ntoh* functions.
- Use socklen_t instead of int.
- Try to define PF_INET to AF_INET if it doesn't exist.
