Hello Robert, and thanks for your comments.
RB> luit seems to lose characters if it's given more than 3-4k very quickly.
I think I've got it. The terminal is put into non-blocking mode, but
writes to it are assumed never to fail (see copyOut). I'll implement
proper output buffering, which will also make luit more efficient.
RB> I notice the CSI 11/12m stuff doesn't work: evil idea DONT try it :-)
Sorry, I don't have my reference handy. Is that some SGR attribute?
RB> Are you going to do ISO646 national sets ?
Yes, if we can work out a set of XLFD names for them. Anybody got
suggestions?
By the way, if you have a map from DEC Technical into Unicode, I'm
interested. There's a semi-standard XLFD for that (-dec-dectech).
RB> Is there any reason you're using X as the build environment using

RB> thought) standard /usr/share/i18n/charmaps character maps?
Yes, portability and flexibility.
The XFree86 font encoding libraries (the files included with luit with
`enc' in the name) don't assume anything about the environment, except
that it is ANSI C and that char is compatible with ASCII.
In addition, adding support for a new encoding is a simple matter of
doing a commit in our CVS tree: I've already included DEC Special
Graphics; how long would it take us to have it included in all
supported platforms?
Note by the way that you don't need to install XFree86; you only need
its encoding files. And hacking a makefile by hand for systems that
don't have Imake is a two-minute job:
CFLAGS = -g -DFONTENC_NOT_IN_X -DSYSTEM_FONT_ENCODINGS_DIRECTORY=...
# optionally -DBSD or -DSVR4, GNU libc systems don't need anything
luit: luit.o iso2022.o ...
I have successfully built a slightly hacked version of luit for stock
Minix this way. (I have needed to hack around the lack of select in
Minix -- Minix luit does busy-waiting.)
RB> It is linux so no-problem but I imagine there may be issues later
RB> with other unices.
I doubt it. I have run luit on two BSD variants and Solaris. One of
the BSDs already had XFree86 4, on the other systems I have needed to
install the encoding files.
Regards,
Juliusz
