2017-06-06Delete input event when evbuffer_read() fails to avoid just spinningnicm
around a dead file descriptor. Seems to fix a problem reported by Greg Hurrell in GitHub issue 941.
2017-06-04Typo/style; plus man page escaping from jmc.nicm
2017-06-03Foreground colours with the bright attribute set need to use the brightnicm
entries in the palette. GitHub issue 954.
2017-05-31It is not OK to ignore SIGWINCH if SIOCGWINSZ reports the size hasnicm
unchanged, because it may have changed and changed back in the time between us getting the signal and calling ioctl(). Always redraw when we see SIGWINCH.
2017-05-31Look for setrgbf and setrgbb terminfo extensions for RGB colour. This isnicm
the most reasonable of the various (some bizarre) suggestions for capabilities.
2017-05-15Check the terminfo(5) U8 capability and disable using UTF-8 for ACS ifnicm
it is present and zero. This is useful for users with terminals or fonts that do not correctly support UTF-8 line drawing characters. GitHub issue 927, reported by Hiroaki Yamazoe and Akinori Hattori.
2017-05-15The Konsole SU bug means it can't clear the entire scroll region (itnicm
ignores if >= size, not if > as I first thought). So we can't effectively fix it in code - remove the workarounds which just cause bugs on other terminals.
2017-05-13Scroll the right number of lines off the region when clearing.nicm
2017-05-13Some other unused variables.nicm
2017-05-12Compare >= for columns not >.nicm
2017-05-12Can scroll away full lines to clear them too.nicm
2017-05-12Cannot rely on cursor position after DL and IL (some terminals move tonicm
column 0, some do not).
2017-05-12Scrolling needs to use background colour.nicm
2017-05-12Regions can't be smaller than 2 so don't try to clear them by scrolling if so.nicm
2017-05-12Can use INDN to clear regions with default background colour if marginsnicm
are supported.
2017-05-12ECH needs to use background colour.nicm
2017-05-11Need to redraw out to cellsize (total cells used in a line) rather thannicm
cellused (only non-space cells) because there may be cells with a nondefault background.
2017-05-10Move to the right cursor position before using spaces to clear.nicm
2017-05-10We can use ECH to clear sections of lines, so use it for internal panesnicm
(that don't touch an edge). Move all the tty clear code into two common functions rather than having the same bunch of checks everywhere.
2017-05-09If the current screen was complex enough, it was possible to make redrawnicm
itself hit the "terminal can't keep up" check. To avoid this, record how much data we send during redraw (we know we will be starting with 0) and skip the check until it has been flushed. GitHub issue 912.
2017-04-28Konsole incorrectly ignores SU (CSI S) if the parameter is bigger thannicm
the scroll region, so clamp it. Reported by Moritz Bunkus.
2017-04-25Make full width panes try to play more nicely with terminal copy andnicm
paste by avoiding explicit line wraps if we think the terminal will wrap anyway.
2017-04-23Only use ED for clear screen if at the bottom, same as earlier fix tonicm
clear end of screen.
2017-04-19When the data we have buffered to write to a terminal grows beyond anicm
reasonable amount (currently width * height * 8 bytes), discard all output to the terminal and start trying to redraw periodically instead. Continue with this until the amount of data we are trying to write falls to a low level again. This helps to prevent tmux sitting on a huge buffer of data when there are processes with fast output running inside tmux but the outside terminal is slow. A new client_discarded format holds the amount of data that has been discarded due to this mechanism. The three variables (when to start this, when to stop, and how often to redraw) are basically "works for me" at the moment, this is going in to see how it goes and if it causes problems for anyone else.
2017-04-18Revert use of DECSLRM on iTerm2, it doesn't help as much as we throught,nicm
and there are some question marks about it's support.
2017-04-18Detect iTerm2 and use DECSLRM for it as well.nicm
2017-04-18Add a format for number of bytes writtent to client, useful for debugging.nicm
2017-04-18Do not check for BCE for a background colour that isn't needed, usenicm
colour 8 instead.
2017-04-17Don't bother moving the cursor for empty lines.nicm
2017-04-17Remove a couple of redraw flags that no longer have any effect.nicm
2017-04-16Use EL1 to clear lines when redrawing the leftmost pane, rather thannicm
spaces.
2017-04-05Give each client a name. This defaults to the tty name as before butnicm
falls back to an alternative if the tty name is not available. This is clearer than overloading the client ttyname member and allows us to remove the path stored in the tty struct, it should always be the same as the client.
2017-03-24Write raw strings in one go rather than character at a time.nicm
2017-03-22Add support for the strikethrough attribute (SGR 9), using the new smxxnicm
terminfo capability. This means there are now nine attribute bits, so anything above 0xff uses an extended cell.
2017-03-15Invalidate the cursor when we think we should have wrapped.nicm
2017-03-15Try to avoid moving the cursor to the start of the next line whennicm
printing cells if it is already at the very end of the line and the terminal will wrap it to the next line itself, this means terminals still see it as a wrapped line for the purposes of their own mouse selection. Reported by millert@.
2017-03-08Always send smkx to the terminal outside, the keys we get from terminfonicm
are the keys when it is on.
2017-03-06Collect strings correctly when on terminals that don't support UTF-8.nicm
2017-02-21Change pane redraw to collect cells up as well, and simplify it a bit.nicm
2017-02-16There are buggy terminals out there that do not move the cursor to 0,0nicm
after CSR, so invalidate the cursor position rather than assuming 0,0.
2017-02-15Do not clear to end of screen unless the pane is at the bottom.nicm
2017-02-10Add not delete the event if more to write.nicm
2017-02-10Don't use a bufferevent for the tty, so we can keep better track of whatnicm
is being written and when. Also a manpage typo fix from jmc@.
2017-02-08Another helper function to write to terminal and log.nicm
2017-02-08Do not adjust region lower by pane offset when scrolling up, it isnicm
already an absolute position.
2017-02-08Add support for scroll up escape sequence (CSI S) and use it whennicm
possible instead of sending individual line feeds.
2017-02-08Collect sequences of printable ASCII characters and process themnicm
together instead of handling them one by one. This is significantly faster. Sequences are terminated when we reach the end of the line, fill the internal buffer, or a different character is seen by the input parser (an escape sequence, or UTF-8). Rather than writing collected sequences out immediately, hold them until it is necessary (another screen modification, or we consume all available data). This means we can discard changes that would have no effect (for example, lines that would just be scrolled off the screen or cleared). This reduces the total amount of data we write out to the terminal - not important for fast terminals, but a big help with slow (like xterm).
2017-02-08Fix clear start of line.nicm
2017-02-08Some other tidying bits.nicm
2017-02-08Remove unnecessary duplicate check.nicm
