[9fans] catenating subfont files, catsf

[YAMANASHI Takeshi]

Ttf2subf is great, but the ouptut subfont files have
been sliced into very small pieces.

For example, I tried ttf2subf on the Cyberbit font and it
produced a font(6) file of almost 2000 lines.  Furthermore,
in cerntain ttf, the result was almost 4000 lines and it
slows rio considerably using the font.

So I made a program catenating multiple subfont files
into a single file.

The following lines would do the installation for you:
	hget http://p9c.cc.titech.ac.jp/plan9/catsf.tgz | gunzip | tar
	cd catsf; mk install

See the manpage included in the tgz for more details.

Wouldn't it be better to fix ttf2subf rather than add more utils to fix
problems with existing ones?

I showed how to do it in a limbo prog I posted here a few months ago.
You map subfonts to standard unicode ranges as defined by unicode.org.
A simple scan determines which pages are present, you then produce subfonts
with 0 width glyphs for
those in a range that do not exist in the source font - causing draw to
render a peterface.
(there are other obvious optimisations to minimise the amount of glyph data
per subfont).

I haven't looked at ttf2subf but the Limbo prog was very simple, it cannot
possibly be that difficult.
Alternatively you could always use my Limbo app.

Looking into ttf2subf is harder than reading plan9 documentations
and writing new program for me. :)

Exactly.  I just overlooked your limbo program or I wouldn't have
write this.  I should have asked the list first.  Anyway, it left
me some experience.
