The gnu emacs info mode supports a lisp function execute feature
upon displaying an info node.
Wow, I never knew that.
Although we could document it and add a Texinfo command to generate it,
I'm worried about security. It should at least be disabled by default,
I would think.
rms, bob, anyone else, what do you think? (Including Joseph's original
message for your benefit.)
Thanks,

Subject: makeinfo function execute feature
The gnu emacs info mode supports a lisp function execute feature upon
displaying an info node. This feature requires placing the "execute:"
keyword after the end of a node and before the beginning of the next
node. For instance, if the lisp function to be executed is the function
"run-test", then the node that causes it to be executed can end with the line
^_execute: (run-test)^L
The makeinfo tool does not have any command built in for putting this
construct into the output stream. I have carefully reviewed the version
4.6 texinfo code to see that the makeinfo/node.c file that puts out all
of the occurances of the ^_ char into the output stream has no context
in which it can be followed by the above "execute: (run-test)" construct.
Whenever I use the node execute, I am prevented by makeinfo from keeping
a single source file for interactive and printed versions of the info file.
It would be nice if makeinfo were modified to add a command for
inserting a function execute attribute after the end of a node.
PS: This feature is not documented in the info manual, but the emacs
info mode source code definitely includes looking for and running any
execute attributes after the end of a node. I have used this feature
for a long time.
