Thanks for reply Doug.

I think the answer to your last question is yes. If I have a correct .mp
file and use the tool I have defined...

#!/bin/sh
mpost "$GEDIT_CURRENT_DOCUMENT_NAME"

...a proper postscript file is created which I can view (evince or
gsview, etc). But if I make changes to the source file (in gedit) the
tab is starred (as expected) but not saved (obviously). The tool then
runs, as far as I can tell--and I can experiment more--on the last saved
version (which may be a ~filename somewhere?) and no changes are made to
the postscript file.

The output must be set to 'Display in Bottom Pane' as that output is the
metapost runtime message (error or otherwise), not the postscript file
for viewing.

I had tried the settings in the tool window before posting my query, but
none seem to save the current text code file before running it through
mpost. What I think I may need is a bash command to save the current
file, then run the saved file through mpost? I tried some, like cp, mv,
but I am floundering. Also went to trying regular expressions to pass a
ctr+s, but more floundering and that seems like the wrong approach
anyway.

Methinks my immediate question boils down to this: how (best) to use
External Tool to save current file? I must be missing something obvious.
