I have been also able to make it work, limiting myself to inserting a table at the beginning of the document for the moment (to Michael - sorry for intruding in your thread, how to insert automatically generated code into a TeXmacs document was something that was in my mind since a while).

Hi Michael,

TeXmacs internally represents all documents as trees.
The current buffer can be retrieved using

(buffer-tree)

You can next use the routines 'tree-ref' and 'tree-set' to
extract subtrees and modify them. For instance, assume that
you created a document with an empty first line and
that you created a Scheme session just below.
Then the buffer tree will be of the form

(document
""
...your Scheme session...)

You may then do

(tree-set (tree-ref (buffer-tree) 0) `(strong "Hi there!"))

to change the first line into a welcome greeting.

I hope that this helps to get you started.
For more info, see "The Jolly Writer", chapter 14.

Best wishes, --Joris

Greetings!

First of all i would like to thank TeXMacs developers heartily
for the great software.

My question is following.

I would like to generate interactively (in notepad manner) some
math, tables and drawings during some not such a big data
analysis. I've managed to generate expression trees and
drawings, for instance, like this

(define (frac x)
(insert `(with "mode" "math" (frac "a" ,x))))

But i cannot put this structure into the document correctly. As
far, as i understand, insert procedure inserts an object at the
cursor position. But the cursor position is right at the next
Scheme] prompt. So the formulae or the drawing are putted, where
next expression should be entered, not at the document itself,
or at the usual position for the result of expression
evaluation.

Scheme] 1
1 ; i mean here

Could this behaviour be changed somehow? Is there any way to
place generated construction at the result position (which would
be ideal) or at the document somewhere?

- Michael Bakhterev, respectfully
