Making a Diff

Making a Diff

[Alain M.]

What is the standard command to generate e diff to submit to Dosemu? I 
have one directory called dosemu-org and one called dosemu-850...

I have a patch to install fonts for CP850 8x14, the original is from the 
debian project 
<http://packages.debian.org/stable/x11/xfonts-terminus-dos> so it is GPL 
and ok for Dosemu

First question: in the etc/dosemu.alias, all lines look like this:

vga10x20-ua  -dosemu-vga-medium-r-normal--20-200-75-75-c-100-ibm-cp1125

but the one I generated has different names:

vga8x14-cp850 -xos4-Terminus-Bold-R-Normal--14-140-72-72-C-80-IBM-CP850

Should I try to convert it? These are the names in the original 
Debian/Terminus project...

Second question: would you like me to include in the patch a "howto" 
with instructions for installing fonts from that package?

thanks,
Alain

This is probably fine, dosemu-vga and xos4-Terminus don't matter. The
rest is just about a case difference and about the font size.

But I'd like to ask:
1. Why an 8x14 font? It seems a bit small, even smaller than the
standard 8x16. Is there also a problem with using bitmap fonts and the
FreeDOS mode/display/chcp technique?
2. It may be better to use unicode. The present SVN code supports
unicode fonts, you can even use the standard
$_X_font="-Misc-Fixed-Medium-R-SemiCondensed--13-120-75-75-C-60-ISO10646-1"
it's small but gives you all the characters you need.
Have a look at

as well.

Just because this is the DOS size... and it is ok on cheaper 800x600 and 
even 1024 displays. Do you suggest an extra size? 16, 20, 24, 28 and 32 
are available, I just think that you want to prevent doesemu to get 
bloated :)

Yes, I am considering the usage with remote X via ssh. With Xfonts it is 
just as fast as local...

I will, looks very interesting :) but... how will Dosemu work with that? 
there must be a translation table somewhere

That is news to me... I thought 14 is the EGA or HGC size, and VGA
uses 16 by default.

The point is more that if 16 is also fine then there is no reason for
the 8x14 font and you could just use univga.

Good point.

There is, in
src/plugin/translate/charsets/cp850.c
using the $_internal_char_set setting.
