Re: ee (easy editor) bugged on 9.0?

Hello Jason,

* Jason Edwards sub.m...@gmail.com, 2027 22:15:
 Thanks for the impressive list of advantages! 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?

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.

cons25 is no more, syscons speaks xterm now, thanks to Ed Schouten and his

Hi Jason,

* Jason Edwards sub.m...@gmail.com, 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.

Hi Stefan,

I'm very sorry for not having checked properly, but you are indeed
correct. I had overlooked one script which replaces the /etc/ttys
which I did not suspect. Sorry for the confusion! With TERM=xterm, ee
indeed works properly on the console.

This is a fresh install. I do make a LiveCD using scripted tools. But
it pretty much is a vanilla FreeBSD install with just some packages
preinstalled (webserver, php, etc). The only relevant changes I think
are a change to /etc/ttys. But when I revert the file back to the

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.
