I am writing such figures in separate, \input'ed .tikz files that I preview
externally (see attached posting).

I see the need for something like this (e.g. my above script will disrespect
the preamble from the main .tex/.lyx file, so the output may not be
accurate). It would be very nice to have fast, proper preview, but...

..I do not think what the GUI should look like. The above does not sound
right yet (a general "selection preview" sounds fragile and not very
user-friendly to me). Maybe one could explicitly wrap such figure code as
external material and preview as such.

Hi again,
I just thought I could/should post my small script for previewing TikZ
pictures:
http://kogs-www.informatik.uni-hamburg.de/~meine/software/scripts/tikz2pdf
I am using it as follows:
- write (/program) your .tikz picture in a separate file (let's call it
foo.tikz)
- start "tikz2pdf foo.tikz &"
- open tikz2pdf_temp.pdf in a PDF viewer with auto-reload feature
(I am using kpdf)
- now continue editing foo.tikz; as soon as you save the file, it will be
conveniently redisplayed
Shortcomings of the script:
- the fixed .tex/.pdf basename of "tikz2pdf_temp"
- you have to manually delete the temp files with "rm tikz2pdf_temp.*"
afterwards
- includes a fixed preamble; maybe you need to add your own latex \usepackage
stuff there (should probably be using a ~/.tikz2pdfrc instead)
- could possibly start the viewer on its own
- needs python 2.4+ (depends on the subprocess module)
Would be interested in any kind of feedback. :-)
