0e88f8ba28 Bug 381: New macro is_cp_ptr_utf8(cp_ptr).
This does not significantly change the generated code but should make
the next commit more readable.

e1fee49fb7 Bug 381: Halve sizeof(struct table_entry).
Before:

   text	   data	    bss	    dec	    hex	filename
  54920	  28528	   3311	  86759	  152e7	src/intl/charsets.o
 516064	  85568	  82112	 683744	  a6ee0	src/elinks

After:

   text	   data	    bss	    dec	    hex	filename
  38958	  28528	   3311	  70797	  1148d	src/intl/charsets.o
 500112	  85568	  82112	 667792	  a3090	src/elinks

So the text section shrank by 15962 bytes.

Measured on i686-pc-linux-gnu with: --disable-xbel --disable-nls
--disable-cookies --disable-formhist --disable-globhist
--disable-mailcap --disable-mimetypes --disable-smb --disable-mouse
--disable-sysmouse --disable-leds --disable-marks --disable-css

62d6db44aa Bug 381: Make codepage data const.
Before:

   text	   data	    bss	    dec	    hex	filename
  25726	  62992	   3343	  92061	  1679d	src/intl/charsets.o
 653856	 120020	  82144	 856020	  d0fd4	src/elinks

After:

   text	   data	    bss	    dec	    hex	filename
  60190	  28528	   3311	  92029	  1677d	src/intl/charsets.o
 688320	  85556	  82112	 855988	  d0fb4	src/elinks

So 34464 bytes were moved from the data section to the text section
and should be more likely to get shared between ELinks processes.

92cb452a9e Rename CONFIG_UTF_8 to CONFIG_UTF8.
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.

e8462980e5 Change "utf_8" to "utf8" in most identifiers.
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.

a01be8bd6b UTF-8: Stepping functions set *count even if an assertion fails.
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.

0748ee8c92 UTF-8: Split UCS_REPLACEMENT_CHARACTER off UCS_NO_CHAR.
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.

8a8fc52eec cp_to_unicode: Simplify and cleanup 2006-08-14 02:19:44 +02:00
Kalle Olavi Niemitalo
85d4c5679c UTF-8 doc: unicode_fold_label_case() may be called for any Unicode character.
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().

143d95e927 UTF-8: Reuse the translation table if it is from the same charset.
This change makes ELinks more efficient and causes bug 782 to occur
far less often.  (That does not mean the bug should not be fixed.)

a14074a763 try_document_key: Convert the key to UCS-4, resolving the FIXME.
This requires compiling cp2u() in even without CONFIG_UTF_8.
I also added an is_kbd_character macro to make try_document_key
more resilient to changes in the definition of term_event_key_T.

5fd284d6a2 The value of UCS_NO_CHAR was bad. There must not be a possibility
to encode it using utf_8_to_unicode. If every unicode_val_T value
could be a result of that function then one must add out param
to the utf_8_to_unicode signaling 'true' UCS_NO_CHAR.

2748d043f9 Autogenerate .vimrc files and put the master in config/vimrc
This changes the init target to be idempotent: most importantly it will now
never overwrite a Makefile if it exists. Additionally 'make init' will
generate the .vimrc files. Yay, no more stupid 'added fairies' commits! ;)

db99a74777 Add support for out-of-tree builds
Involves prefixing with $(srcdir) to some of the build rule variables. For
the builddir we create Makefiles which simply include the srcdir Makefile.
Add list make rule to get list of Makefiles to generate (find will get it
wrong for builddirs nested in srcdir).

There are still a few minor issues like the file paths echoed during make
install ...

68de9e35d3 Automagically link in subdir lib.o files
It is a little ugly since I couldn't get $(wildcard) to expand *.o files

1efab31581 Simplify building of and linking with directories
Ditch the building of an archive (.a) in favour of linking all objects in a
directory into a lib.o file. This makes it easy to link in subdirectories
and more importantly keeps the build logic in the local subdirectories.

Note: after updating you will have to rm **/*.a if you do not make clean
before updating.
