I've tried to use the supplied AUX curses library, and run into some troubles: 1) The input may allow 8bit characters after calling meta ( ), but the screen sure doesn't. 2) A_BOLD changes the spacing of the text as well as boldifying it. Making this work in a sensible way would be trivial. (This might be how CommandShell is handling the escape sequences. Still a piece of cake) 3) The keypad ( ) numbers don't work very well either - the arrow keys aren't reported until I press another key after them. This even though I use nodelay ( ) . 4) Pressing the left key using TERM mac2 (the large console window) results in immediate crash (some error reports rolled by too fast for me to read before I was logged out) Maybe I would like a way to make CommandShell generate function key codes as well. Wouldn't it be nice ? The software has to be portable, so I can't use native mac windowing :-( This is all on a 8/80 IIfx with 13" 8bit color set to 1 bit and various extra hardware. I compile with gcc, since the native CC doesn't support ANSI style function prototypes. Otherwise the A/UX 2.0 is fairly vanilla off the CD. It doesn't work in the console emulator either, so you can't blame the mac environment. Thanx for any answer, h+ Jon W{tte, Stockholm, Sweden, h+@nada.kth.se :: This article is fake.

The choices under A/UX are: curses(3X) curses(3X) NAME curses - CRT screen handling and optimization package SYNOPSIS #include <curses.h> cc [flags] files -lcurses [libraries] This one uses terminfo to do its stuff. The alternative is: curses5.0(3X) curses5.0(3X) NAME curses5.0 - BSD-style screen functions with optimal cursor motion SYNOPSIS cc [flags] files -lcurses5.0 -ltermcap [libraries] This one uses termcap, as its synopsis implies, and so probably has at least minor differences in behaviour compared to the terminfo version. Note that the synopsis for this one is wrong, because the files in /usr/lib are: -rw-r--r-- 1 bin bin 44044 Jul 18 1990 /usr/lib/libcur5.0.a -rw-r--r-- 1 bin bin 160428 Jul 18 1990 /usr/lib/libcurses.a and so you'd need to use "-lcur5.0 -ltermcap" instead. >2) A_BOLD changes the spacing of the text as well as boldifying it. > Making this work in a sensible way would be trivial.

Still a > piece of cake) This is a problem due to the CommandShell - it tries to get bold text (as distinct from reverse mode and underline mode) by the old daisywheel trick of overstriking after moving one pixel to the right. With the exception of monospaced fonts (such as Courier and possible Monaco?) the bold characters are normally different widths from the plain ones and so using the real bold fonts wouldn't help that much. >3) The keypad ( ) numbers don't work very well either - the arrow > keys aren't reported until I press another key after them.

This is due to a bug in the handling of multi-byte character sequences with select/raw mode input - it was described on this newsgroup some while ago and I worked away at it a bit and sent in a proper SPR on it. >...

The console emulator behaves differently from the CommandShell, and differently from the "term" program from A/UX 1.1 days. My ideal solution to the CommandShell terminal emulation problem is to use the much vaunted Comms Toolbox and have a CommandShell whose terminal emulation was provided by a Comms Toolbox terminal tool: we could then plug in our own terminal types as required. -- William Roberts ARPA: liam@cs.qmw.ac.uk Queen Mary & Westfield College UUCP: liam@qmw-cs.UUCP Mile End Road AppleLink: UK0087 LONDON, E1 4NS, UK Tel: 071-975 5250 (Fax: 081-980 6533)

A good solution ! Meanwhile, I'm disgruntedly forced to work in the SPARC this has to be compatible with. h+ Jon W{tte, Stockholm, Sweden, h+@nada.kth.se :: This article is fake.
