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
