Unfortunately, this is actually a workaround for a problem that existed all along, even before we switched to TERM=xterm. It's not beautiful, but needed. When using TERM=cons25, ncurses applications simply print certain bytes to do the box drawing, namely these ones: http://en.wikipedia.org/wiki/Code_page_437#Standard_code_page This means that if you load a different font file into the console driver that uses a different character set (e.g. ISO-8859-1), you get all sorts of math characters and diacritics instead of the box drawing characters. With TERM=xterm, this is essentially solved, because box drawing can be performed using character set independent escape sequences (using ^N and ^O), but the problem is that syscons does not know which glyphs in the font file correspond with the box drawing characters. There are two ways to solve this: - Extend the font file format to include a mapping table of box drawing characters to glyph indices, - Patch syscons to just print +-| instead of the box drawing characters. The first option would fix it properly, but in my opinion it's not worth the effort, because time should be spent to just get Unicode working. The terminal emulator already supports Unicode internally and even remaps box drawing characters to Unicode. Get Unicode working and you fix the box drawing issue for free. This is why I have chosen the second option. If you really miss the box drawing characters, you can revert SVN revision 203659. Do keep in mind that it effectively breaks support for custom fonts/character sets. I think box drawing does work when you compile your kernel with TEKEN_UTF8 (poor mans UTF-8 support), but please don't attempt to load any fonts then.

There's just one non-critical issue I'd like to address regarding the use of xterm terminal type. When using cons25 terminal, the dialog menus (drawn using devel/cdialog and `make config` in portstree as well) are using smooth lines to draw boxes and stuff. But when using xterm terminal, those lines are replaced by 'dashed' lines like - - - - - instead of a smooth line without whitespace in between. When doing the same via SSH login, the lines are smooth with xterm type. So this issue appear to be limited to the console in combination with xterm terminal type. Is there a way to use xterm but still allow cdialog to draw smooth lines on the console?

Hi Jason, * Jason Edwards , 2022 21:56: > I wonder: is cons25 bugged or simply obsolete? Not that I want to keep > cons25; just being curious. There are two reasons why I changed the default terminal emulator to be xterm-like, instead of conforming to cons25: - It is more compatible. Not all operating systems have proper cons25 entries in their termcap/terminfo, meaning it is practically impossible to SSH to one of those systems and do your work properly. Also, there are many devices (e.g. Cisco/HP switches) that don't offer a lot of flexibility with respect to terminal handling. By using an xterm-style emulator, this is all solved, because xterm is pretty much compatible with VT100 and friends. - It is more bandwidth efficient. cons25-like terminals do not (have to) support more advanced features like scrolling regions. This means for example that if you use applications where only a portion of the screen scrolls (e.g. irssi, mutt), it has to redraw that entire portion of the screen, instead of being able to simply scroll that independent region, without affecting the rest of the display contents. This is of course no problem when running applications locally, but it does have its advantages when SSHing to another system. - It is more future proof. There are many implementations of xterm-like terminals that demonstrate that it's not hard to get (a sane subset of) UTF-8 and 256 colors working. Things like that are simply not available for cons25. As people pointed out, if you still want to keep on using TERM=cons25 (not advised, though), you _MUST_ either compile your kernel with TEKEN_CONS25 or run vidcontrol -T cons25. This is due to the fact that cons25-like terminals are incompatible with xterm-like terminals. For example: - With xterm, ^N and ^O are used to switch character maps, while with cons25, they render a music note and star symbol. - With xterm, processing backspace while the cursor is at the first column of the screen does nothing, while cons25 performs reverse line wrapping. - With xterm, ^L is interpreted as a newline, while with cons25, it clears the entire screen. - With xterm, line wrapping of the cursor on a display of n columns wide is only performed when printing the n+1'th character, while cons25 already does this after the n'th character. Effectively, this makes it very hard to print a character in the lower righthand corner of the screen. One of these incompatibilities is likely what caused the problems you experienced when you ran ee(1) without updating /etc/ttys accordingly. -- Ed Schouten WWW: http://80386.nl/ pgpjoclhMhX6j.pgp Description: PGP signature

On the console it is bugged. As I suspected. On my fresh 90-RC1 install, I get xterm for all the console terminals. You'll have to check where your /etc/ttys picks up the old entries. Both stable and releng have the updated version, as far as I can tell. If your /etc/ttys has ttyv0 "/usr/libexec/getty Pc" xterm on secure and so on, you'll need to check whether a login script resets the TERM environment variable.

On the console it is bugged. i just grabbed a copy of "FreeBSD-9.0-RC2-amd64-dvd1.iso" and ran it in qemu. i noticed nothing irregular running ee. also TERM is set to "xterm" on the console. so this is either an issue with bash (have you tried running sh?) or something in your /etc is broken. cheers. alex > > Regards, > Jason ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
