[Texmacs-dev] Ideas for the switch environment/strange bug

[Álvaro Tejero Cantero]

I have been thinking on how to make usable outside of interactive
TeXmacs the switch environment.

I like to call it "frame", because it conveys to me the idea of a video
frame. But I disgress...

I have been making some slides, and now want to export to ps or print. I
cannot. One would propose to concatenate in different pages the slides
and then print. But that approach would leave apart the educational use
of switch (imagine a complicated mathematical expression which turns
into a low-dimensional example when you hit M-A-right). So what is
needed IMHO is two "unroll" commands that make the (possible) tree of
switches into switches into a sequence and offer to insert intermediary
page breaks. That way you could do a global unroll for the sequential
media. This would be useful for the two use cases I have in mind: 

1) slides.
2) educational innovation.

Is this doable in scheme?


I attach now my slides because I have a funny behaviour with TM ..1.5
when creating a new document and trying to insert \copyleft. In general
TeXmacs has been much more prone to crashes when this document was
loaded.

Fatal error: lost sync in pk file (character too big / status =  6 in
'load_pk'.
See file: 'load-pk.gen.cc

have fun, álv.
