Re: [Texmacs-dev] Split atomic tree

[Michael Klein]

Hello Joris,

I will use your second suggestion and replace the string directly.

Best regards
Michael

Please give a more explicit example of what you want to do.

I also recall that tree-split is a low-level tree modification routine.
When splitting a string, a new argument gets inserted into the parent tag
(section in your case); what else to do? If your aim was to insert something
like a fraction in between, then you should first replace your string s
by (concat s) and then split it twice.

However, it is easier to directly use the tree-set routine and
replace your string s by (concat s1 (fraction "" "") s2), for instance.
The only reason why you might want to use a low-level routine tree-split
is to keep a very precise control over the cursor.

Best wishes, Joris
