* Fix crash on load of bigger font. It reduce width and height of terminal, butray2014-02-061-0/+17
| | | | | | | | | current cursor position stay bigger that terminal window size, so next input triggers assert. Reported by: emaste Sponsored by: The FreeBSD Foundation
* Fix linewrapping behaviour for CJK fullwidth characters.ed2013-12-231-5/+10
| | | | | | | | Instead of only wrapping when in the 'wrapped state', also force wrapping when the character to be rendered does not fit on the line anymore. Tested by: lwhsu
* Extend libteken to support CJK fullwidth characters.ed2013-12-203-16/+16
| | | | | | | | | | | | | Introduce a new formatting bit (TF_CJK_RIGHT) that is set when putting a cell that is the right part of a CJK fullwidth character. This will allow drivers like vt(9) to support fullwidth characters properly. emaste@ has a patch to extend vt(9)'s font handling to increase the number of Unicode -> glyph maps from 2 ({normal,bold)} to 4 ({normal,bold} x {left,right}). This will need to use this formatting bit to determine whether to draw the left or right glyph. Reviewed by: emaste

* Simply let teken_stress use arc4random.ed2011-10-071-11/+1
| | | | | This makes it run quite a bit faster, since it makes system calls less often.
* Tab should not blank cells.ed2011-10-071-14/+1
| | | | | | | | | | | | It seems I was under the impression that a tab differs from a single forward tabulation, namely that it blanks the underlying cells. This seems not to be the case. They are identical. This should fix applications like jove(1) that use tabs instead of explicit cursor position setting.

* Add proper build infrastructure for teken.ed2011-05-0910-28/+305
| | | | | | | | | | | I'm not sure whether we should install teken as a library on any stock FreeBSD installation, but I can imagine people want to tinker around with it now and then. Create a /sys/teken/libteken, which holds a Makefile to install a shared library version of the terminal emulator, complete with a manpage. Also add Makefiles for the demo/stress applications, to build it against the shared library.
* Use proper bounds checking on VPA.ed2010-12-051-2/+1
| | | | | | | | We must check against tp->t_cursor.tp_row, not row, to figure out whether we must clamp the cursor position. Submitted by: luigi MFC after: 3 weeks
* Partially implement the mysterious cons25 \e[x escape sequence.ed2010-11-052-0/+15
| | | | | | | | | | | | | | It seems the terminfo library on some systems (OS X, Linux) may emit the sequence \e[x to reset to default attributes. Apart from using the zero-command, this escape sequence allows many more operations, such as setting ANSI colors. I don't see this used anywhere, so this should be sufficient for now. This deficiency was spotted by the Debian GNU/kFreeBSD. They have their own patch, which is slightly flawed in my opinion. I don't know why they never reported this issue to us. MFC after: 1 week
* Make ^L with cons25 and origin mode bit more sane.ed2010-08-091-3/+9
| | | | | | | | Even though cons25 normally doesn't support origin regions, this emulator does allow you to do it. It makes more sense to blank only the origin region when emitting ^L instead of blanking the entire screen. Apart from that, we should always place the cursor inside the origin region, which doesn't happen right now.
* Just use <stdint.h> instead of <inttypes.h>. We don't need it here.ed2010-04-031-1/+1

* Fall back to ASCII codepoints for box drawing.ed2010-02-081-5/+5
| | | | | | | | Even though the default VGA font provides box drawing fonts, there is no guarantee any font will provide these as well (i.e. ISO-8859-*, KOI8-R). Just use ASCII characters for box drawing. PR: kern/141633
* Place home and end before insert and delete.ed2009-11-112-6/+6
| | | | | | These keys have different sequences when using cursorkeys, while insert and delete stay the same. If they are placed like this, libteken will return NULL instead of a proper sequence for these characters.
* Allow Syscons terminal emulators to provide function key strings.ed2009-11-113-17/+104
| | | | | | | | | xterm and cons25 have some incompatibilities when it comes to escape sequences for special keys, such as F1 to F12, home, end, etc. Add a new te_fkeystr() that can be used to override the strings. scterm-sck won't do anything with this, but scterm-teken will use teken_get_sequences() to obtain the proper sequence.
* Always home the cursor when changing the scrolling region.ed2009-11-111-7/+8
| | | | | | | | | | I thought this only had to be done when in origin mode, to ensure that the cursor is not placed outside the origin, but it seems this is also done when not in origin mode. This fixes some artifacts when pressing ^L while running irssi in tmux. (Almost) nobody noticed this, because cons25 doesn't have scrolling regions.
* Discard Device Control Strings and Operating System Commands.ed2009-10-083-3/+35
| | | | | | | | | | | | | | These strings often contain things like: - Window titles. - Extended key map functionality. - Color palette switching. We could look at these features in the future (if people consider them to be important enough), but we'd better discard them now. This fixes some artifacts people reported when using TERM=xterm.

* Add support for VT200-style mouse input.ed2009-09-272-0/+7
| | | | | | | | | | | | | | | | | | | Right now if applications want to use the mouse on the command line, they use sysmouse(4) and install a signal handler in the kernel to deliver signals when mouse events arrive. This conflicts with my plan to change to TERM=xterm, so implement proper VT200-style mouse input. Because mouse input is now streamed through the TTY, it means you can now SSH to another system on the console and use the mouse there as well. The disadvantage of the VT200 mouse protocol, is that it doesn't seem to generate events when moving the cursor. Only when pressing and releasing mouse buttons. There are different protocols as well, but this one seems to be most commonly supported. Reported by: Paul B. Mahol <onemda gmail com> Tested with: vim(1)
* Add 256 color support.ed2009-09-265-3/+90
| | | | | | | | | | | | | | It is quite inconvenient that if an application for xterm uses 256 color mode, text suddenly starts to blink (because of ;5; in the middle). We'd better just implement 256 color mode and add a conversion routine from 256 to 8 color mode, which doesn't seem to be too bad in practice. Remapping colors is done quite simple. If one of the channels is most actively represented, primary colors are used. If two channels are most actively represented, secondary colors are used. If all three channels are equal (gray), it picks between black and white. Reported by: Paul B. Mahol <onemda gmail com>
* Properly get out of origin mode if the cursor has to move outside of it.ed2009-09-261-3/+12
| | | | | | | | | | | | | In some cases events may occur that move the cursor outside the scrolling region while in origin mode, which is normally not possible. Events like these include: - Alignment test. - Restore cursor. Properly switch off origin mode in these cases. MFC after: 1 month
* Get rid of now deprecated SCS wrappers.ed2009-09-263-42/+14
| | | | | We always build SCS, even when processing 8-bit data. There is no reason why we should be able to disable it now.
* Make the fuzzer a bit more useful by forcing 7-bit data into it.ed2009-09-261-2/+11
| | | | | | Getting valid UTF-8 sequences is quite unlikely, so we'd better just convert data to 7 bits and make it extra likely for escape sequences to occur.
* Add a new escape sequence to switch between cons25 and xterm.ed2009-09-252-0/+15
| | | | | | | | | | | | | Just run this to switch to xterm: printf '\e[=T' If you get bored and want to switch back to cons25, run this: printf '\e[=1T' I can now send an email to the lists, asking whether people are interested in trying the xterm emulator.
* Conformance: ignore {delete,insert} line while outside the scrolling region.ed2009-09-251-0/+10
| | | | | | | | | | | | | I noticed a small inconsistency in delete and insert line between xterm and libteken. libteken allows these actions to happen while the cursor is placed outside the scrolling region, while xterm does not. This behaviour seems to be VT100-like. Confirmation: http://www.vt100.net/docs/vt102-ug/chapter5.html "This sequence is ignored when cursor is outside scrolling region." MFC after: 1 month
* Add __unused.ed2009-09-241-1/+1
| | | | | It turns out my previous commit does survive a buildkernel, but not compilation of the individual test tools that use WARNS=6.
* Make SCS work in 8-bit mode.ed2009-09-244-13/+24
| | | | | | | | | | | | | | | | | | | | | | | This means we can finally do things like VT100 box drawing when using Syscons (8-bit characters). As far as I know, the only remaining issue is the absense of proper escape sequences for special keyboard characters (cursor, F1 to F12, etc) and xterm emulation should be ready for general use. Enabling xterm would have the following advantages: - Easier possible migration to Unicode. cons25 termcap entries are very 8-bit centric. They use things like CP437 characters for box drawing, etc. - Better support for SSH'ing to other operating systems/devices. Most switches use VT100-style admin interfaces. - Reduced bandwidth, because applications can now use things like scrolling regions. - You can finally use applications like dtach(1) on both the console and inside an xterm.
* Commit all local modifications I have to libteken:ed2009-09-125-102/+122
| | | | | | | | - Make xterm/cons25 support runtime configurable. This allows me to share libteken between syscons and my new vt driver. - Add a fix to print blanks after printing a double width character to prevent rendering artifacts. - Add some more utility functions that I use in the vt driver.
* Small style(9) bug introduced in the previous commit.ed2009-09-121-2/+2

* Make 8-bit support run-time configurable.ed2009-09-124-47/+37
| | | | | Now to do the same for xterm support. This means people can eventually toy around with xterm+UTF-8 without recompiling their kernel.
* Make resizing of teken terminals a bit more safe.ed2009-09-122-4/+4
| | | | | | Just perform a full reset when resizing the terminal. This means the cursor, scrolling region, etc. are never positioned outside the terminal.
* Expose the TF_REVERSE flag to the console driver.ed2009-09-033-21/+3
| | | | | | | | | | | | | | | Right now libteken processes TF_REVERSE internally and returns the toggled colors to the console driver. This isn't entirely correct. This means that the bold flag is always processed by the foreground color, while reversing should be done after the foreground color has been set to a brighter version by the bold flag. This is no problem with the syscons driver, because with VGA it only supports 16 foreground and 8 background colors. My WIP console driver reconfigures the graphics hardware to disable the blink functionality and uses 16 foreground and 16 background colors. This means that this driver will handle the TF_REVERSE flag a little different from what syscons does right now.
* Move libteken out of the syscons directory.ed2009-09-0311-0/+2897
I initially committed libteken to sys/dev/syscons/teken, but now that I'm working on a console driver myself, I noticed this was not a good decision. Move it to sys/teken to make it easier for other drivers to use a terminal emulator. Also list teken.c in sys/conf/files, instead of listing it in all the files.arch files separately.
