Hi Bill,
Yes, TeXmacs has made huge progress over the last few years, and is
continuing to do so.
Just as one example, the Fricas interface typesets the integral on p. 66
of the Fricas book with
very nice line breaking.
To answer your questions, I am not a very sophisticated Fricas user, so
I don't write SPAD code.
But, more importantly, TeXmacs is not really a programmer's editor like
Emacs. It is an editor for
scientific (technical) documents. (Nevertheless, it knows how to
typeset fragments of many programming
languages so they look good when included in a document. By "programming
languages" we also mean
computer algebra systems.) So for writing SPAD code I would use Emacs,
or some other IDE, if you prefer.
With respect to including graphics in a document, there is a
sophisticated interface that handles eps, pdf, png.
You can access it by the button with the picture of a tree in the second
row of the buttons at the top of the window.
To understand it in detail, the TeXmacs help system is very good, like
that of Emacs. E.g., Help -> Search -> Documentation, and then typing
"picture" gives a number of hits, the relevant one being "inserting images".
Even better, if you are not adverse to reading manuals, the full TeXmacs
manual in PDF is an excellent source:
http://www.texmacs.org/tmweb/help/learn.en.html
This contains all of the material in the "Help" menu in one document.
For images, see sec. 5.2.

Kostas,
Thank you for the link to the updated Linux binaries for TeXmacs.
After some initial testing I think things seem to have improved
significantly since the last time I used TeXmacs and FriCAS together a
few years ago. TeXmacs seems more reliable and more responsive than it
did back then. I had no problem accessing FriCAS immediately after
installing TeXmacs and Greek characters and other special symbols
worked as expected. I will probably try using this combination for my
next FriCAS project.
I have a couple of questions. Do you also use TeXmacs to edit SPAD
code? If so, do you have any "best practices" advice about editing,
compiling and running custom SPAD code in this environment? Second, is
there some way to embed FriCAS-generated graphics/plots into TeXmacs
documents?
Maybe this is a good time to put a little more emphasis on this
alternative user interface for FriCAS.
Bill Page.

Thanks to everyone who helped resolve this problem.
As an aside, if anyone wants to try the latest TeXmacs, there are
*static* binaries for Linux now available, which should make the
installation painless:

(There seem to be static binaries for MacOS and Windows as well.)
