dd46f634fe Now we are correctly not redrawing the whole pane on linefeed, redo the 
last-cursor-position code to move to the right position when panes reach EOL.

af2b0f452c Tweak descriptions for up/down pane to be clearer. 2009-10-21 13:48:27 +00:00

9b5da97e6f Don't redraw the scroll region on linefeed/reverse index unless it is necessary 
(the cursor is at the bottom/top). Should fix slow cursor movement when using
vi in a pane spotted by pirofti@.

683ddbc466 Some terminals don't correctly clear their let's-wrap flag after changing the 
scroll region (which moves the cursor to 0,0). This means that if the cursor
was at the edge of the screen, any further output after scroll region change
incorrectly causes a line wrap. Add a workaround to move the cursor to position
0 if it is at the screen edge before changing scroll region.

7825871d6a Getting the read and write ends of the pipe the right way round is usually 
recommended. DOH.

6f2169037e Sort out stdout before stdin/stderr in case the stdout side of the pipe got one 
of their fds.

1af09d6330 Try to reduce the UTF-8 mess. 
Get rid of passing around u_char[4]s and define a struct utf8_data which has
character data, size (sequence length) and width. Move UTF-8 character
collection into two functions utf8_open/utf8_append in utf8.c which fill in
this struct and use these functions from input.c and the various functions in
screen-write.c.

Space for rather more data than is necessary for one UTF-8 sequence is in the
utf8_data struct because screen_write_copy is still nasty and needs to reinject
the character (after combining) into screen_write_cell.

62f234ce3b UTF-8 combined character fixes. 
Thai can have treble combinations (1 x width=1 then 2 x width=0) so bump the
UTF-8 cell data size to 9 and alter the code to allow this.

Also break off the combining code into a separate function, handle any further
combining beyond the buffer size by replacing the character with _s, and when
redrawing the UTF-8 character don't assume the first part has just been
printed, redraw the entire line.

387f4d42cc Move the check for whether to force a line wrapper lower down into the tty code 
where it has access to the tty width, which is what should have been checked.

confused.

daa26079ee Always move the cursor position on !xenl terminals, since there is no invisible 
last cursor position.

Also nuke an unused variable.

fe26b5d25f Don't print wide characters at screen width - 1. Matches uterm behaviour and 
is probably a better idea anyway.
 2009-10-17 08:32:18 +00:00

43d62c1ae3 Instead of having a complicated check to see if the cursor is in the last 
position to avoid an explicit wrap, actually move it there.

Some UTF-8 fixes to come.

70355021d8 When checking whether the region will scroll and the cursor position is thus 
unsuitable for using CUD/CUU, check the current cursor position not the target
position.

ad566a86de Move lines into the history when scrolling even if the scroll region is not 
the entire screen.

Allows ircII users to see history, prompted by naddy.

38df960e68 Add mode keys to move the cursor to the top, middle and bottom of the screen. 
H/M/L in vi mode and M-R/M-r in emacs (bottom of screen not bound in emacs).

0907ca1931 Do this in a better way - print messages when exiting with nonzero. 
Also remove the login shell information from server-info, only the client
should care about it.

4dcb5040a0 Instead of using something sort of similar for both newline checks, use 
something the same. Doesn't fix the bug I'm looking for though :-/.

d7626cd9d7 When drawing lines that have wrapped naturally, don't force a newline but 
permit them to wrap naturally again. This allows terminals that use this to
guess where lines start and end for eg mouse selecting (like xterm) to work
correctly.

This was another long-standing issue raised by several people over the last
while.

Thanks to martynas@ for much testing. This was not trivial to get right so
bringing it in for wider testing and adn to fix any further glitches in-tree.

8608c6970d When backspace is received at the beginning of a line and the previous line was 
wrapped, move the cursor back up to the end of the previous line.

Another one of the forgotten persons requested this quite a while ago (I need
to start noting names on todo items...) when it was quite hard to
implement. Now it is easy and I don't see it can do any harm, so hey presto...

693b3d03e6 Don't run through the column unchanged case if the row was unchanged but there 
were no suitable optimisations, instead make it an else to fall through to
absolute addressing.

eb9826f65d If the vertical cursor movement crosses the scroll region, CUU and CUD 
shouldn't be used even if VPA isn't present - in that case CUP should be used.

56157444de Wrap a couple of long lines. 2009-10-12 16:33:39 +00:00

0aab5811ca Use absolute movement if right at the end of the line as it isn't a reliable 
place to move from relatively.
 2009-10-12 14:54:19 +00:00
Nicholas Marriott
687c4a9fab Use relative cursor movement instead of absolute when possible and when 
supported by the terminal to reduce the size of the output data (generally
about 10-20%).

762459954f Similarly add a tty_cursor_pane function to tidy up most of the calls. 2009-10-12 09:29:58 +00:00

972a6f5656 _absolute is redundant, just use tty_region. 2009-10-12 09:16:59 +00:00

f05b32f7ad Cleanup: use two functions for region setting, one for absolute and one inside 
pane.

0a2a354499 Like linefeed, don't set the scroll region for reverse index unless it will be 
needed.

While here, also tidy up a couple of long lines and remove an extraneous blank.

fbb030d7f7 Set the current window pointer to NULL when killing a winlink that is to be 
replaced with link-window -k. This prevents it being pushed onto the last
window stack and causing a use-after-free.

Only took me an hour to find this :-/...

64b5f39656 Add a pipe-pane command to allow a pane to be piped to a shell command, for 
example:

	pipe-pane 'cat >~/out'

No arguments stops outputing and closes the pipe; the -o flag toggles a pipe
and on and off (useful for key bindings).

4bc0f6e7e9 Clean up by introducing a wrapper struct for mouse clicks rather than passing 
three u_chars around.

As a side-effect this fixes incorrectly rejecting high cursor positions
(because it was comparing them as signed char), reported by Tom Doherty.
