Added EVENT_TEXTAREA used to notify the master terminal
about end of execution of an external program on a slave terminal.
The format of data sent to the master terminal by exec_on_slave_terminal
has changed. Now after 0, fg the value of term is sent.
Therfore this release of ELinks is incompatible with previous releases.
Patch by Witold Filipczyk, taken from his witekfl branch.

Pass the session with some get_opt_* calls. These are the low-hanging fruit. Some places will be difficult because we don't have the session or for other reasons.
Update a comment in encode_multipart, which refers to html_form_control, which has since been renamed to html_special_form_control.
The comment was added with this commit:

Don't decode and back encode hidden form items (by mikulas, from 0.97).
The function was renamed with this commit:

html_(tag|form*) -> html_special_\1, to naming prevent conflicts with HTML element handlers. As suggested by Jonas.
I don't remember why I cleared "returns", but it doesn't work
with www.hypermedia.pl/altkom/ and probably with many more sites.

Use it for the actual I/O only. Previously, defining CONFIG_UTF8 and
enabling UTF-8 used to force many strings to the UTF-8 charset
regardless of the terminal charset option. Now, those strings always
follow the terminal charset. This fixes bug 914 which was caused
because _() returned strings in the terminal charset and functions
then assumed they were in UTF-8. This reduction in the effects of
UTF-8 I/O may also simplify future testing.
Previously, html_special_form_control converted
form_control.default_value to the terminal charset, and init_form_state
then copied the value to form_state.value. However, when CONFIG_UTF8
is defined and UTF-8 I/O is enabled, form_state.value is supposed to
be in UTF-8, rather than in the terminal charset.
This mismatch could not be conveniently fixed in
html_special_form_control because that does not know which terminal is
being used and whether UTF-8 I/O is enabled there. Also, constructing
a conversion table from the document charset to form_state.value could
have ruined renderer_context.convert_table, because src/intl/charsets.c
does not support multiple concurrent conversion tables.
So instead, we now keep form_control.default_value in the document
charset, and convert it in the viewer each time it is needed. Because
the result of the conversion is kept in form_state.value between
incremental renderings, this shouldn't even slow things down too much.
I am not implementing the proper charset conversions for the DOM
defaultValue property yet, because the current code doesn't have
them for other string properties either, and bug 805 is already open
for that.
I am going make fc->default_value use the charset of the document, and
recoding the string from the form history to that might lose characters.
This change also affects what ECMAScript sees in the defaultValue property.
<http://www.w3.org/TR/2003/REC-DOM-Level-2-HTML-20030109/html.html#ID-26091157>
says it should represent the HTML "value" attribute, so changing it
based on form history is not appropriate.
straconcat reads the args with va_arg(ap, const unsigned char *),
and the NULL macro may have the wrong type (e.g. int).
Many places pass string literals of type char * to straconcat. This
is in principle also a violation, but I'm ignoring it for now because
if it becomes a problem with some C implementation, then so will the
use of unsigned char * with printf "%s", which is so widespread in
ELinks that I'm not going to try fixing it now.
In goto_mark, copy the current_link of the old view state to the
old_current_link of the new view state so that clear_link will properly
clear the highlight for that link.
This fixes a bug introduced with the removal of link_bg in commit
c91c763d49bc7cd01aa06c0dabbd15fecc97da80.
* Recompute the pos variable for each cell, rather than just once per line.
This fixes the bug that only the first cell was being examined.
* Moved the bulk of the code outside the "if (frame && data >= 176 &&
data < 224)" conditional. This fixes the bug that only frame
characters were being added to the string.
* If the cell has UCS_NO_CHAR in it, don't add that to the string.
* Call encode_utf8 even for characters that originated from a frame.
This does not matter yet but will be correct if the function is
later changed to use the Unicode line-drawing characters for frames.
This allows code to use document->cached instead of
find_in_cache(document->uri), thereby increasing the likelihood
of getting the correct cache entry.
This should fix Bug 756 - "assertion (cached)->object.refcount >= 0 failed"
after HTTP proxy was changed.
Patches for this were written by me and then later by Jonas.
This commit combines our independent implementations.
As draw_textarea_utf8 loops over each character of the textarea content, it
checks whether the character is on the screen; draws it if so; increments
the screen co-ordinate; and updates the position in the textarea text.
The last step was being skipped when the character was not on the line,
so a line would be drawn from the beginning, even if the left edge of the
textarea is off the screen.
Closes: Bug 835 - Text in textarea is unaffected by horizontal scrolling of
document in UTF-8 mode
If utf8_char2cells isn't told where the string that contains
the given UTF-8 character ends, it computes that itself. Two users
of utf8_char2cells, format_textutf8 and split_line, were calling
utf8_char2cells in a loop without providing the end of the string,
resulting in numerous calls by utf8_char2cells to strlen.
With this patch, format_textutf8 and split_line each find the end
of the string once and provide it to utf8_char2cells.
This particularly improves performance with textareas, since
format_textutf8 is called multiple times each time the user interacts
with the textarea and when it must be redrawn.
Closes: Bug 823 - Big textarea is too slow with CONFIG_UTF8
UCS_ORPHAN_CELL is currently defined as U+0020 SPACE, which was
already used before this macro, so the behaviour does not change,
but the code seems clearer now.
I searched for ' ' and 32 and 0x20 and \x20, and replaced with
UCS_ORPHAN_CELL wherever UCS_NO_CHAR was involved. However,
some BFU widgets first draw spaces and then overwrite with text;
those will require a more complex fix if UCS_ORPHAN_CELL is ever
changed to some other character.
