two suggestions to \typesetbuffer

[Pablo Rodriguez <oinos@gmx.es>]

Dear Hans,

I have presentations that include buffers typeset with \typesetbuffer.

One of the presentation includes 33 buffers, which are small ConTeXt
samples.

Any time I change anything on the presentation (not on the buffers
themselves), every buffer is typeset again. And the compilation time is
longer than probably desired.

My first suggestion would be to skip compiling buffers again, if the
following three requirements are met:

1. Buffer content (.tmp file, I guess) is identical (checked with a
hash) with the previous one from last compilation.

2. PDF file hasn’t been changed since previous complete compilation (md5
sum again).

3. Buffer content was correctly compiled in previous compilation.

My second suggestion may be a bit complex to implement, but I think it
would be useful. Wouldn’t it be possible that the fonts are only
embedded one in the presentation?

Many thanks for your help,


Pablo
