When you define a converter in LyX it's all pretty static. In my case,
# FORMATS SECTION ##########################
\format "beamer.info" "pdf.info" "Info (Beamer)" "" "leafpad"
"leafpad" "document,menu=export"
# CONVERTERS SECTION ##########################
\converter "pdf2" "beamer.info" "makebeamerinfo -p $$i" ""
However, 'makebeamerinfo' [1] supports several presets via cli
switches and via an ENV var [2]. For example, teh user can
-t clean makebeamerinfo's default, pageturn and wiperight
default that is, Impressive's default selection
sane selections which make sense for a Beamer presentation
or use the (exported) environment variable $MAKEBEAMERINFO_TRANSITIONS
to control this, prior to running the script.
The catch is that the user may reasonably expect/want to be able to
change this setting from one run to the other. I'm not very familiar
with this part of LyX, but I can see only two readily available ways
to achieve that:
- define three different converters, each using a different '-t'
setting. This is overkill, and would never be accepted in base LyX in
such a state.
- modify the converter prior to each run. Another overkill.
So we're at a loss as to how to elegantly allow users to modify this
setting between two subsequent runs. We hoped that an ENV var could
solve the issue. Ideas?
