Custom Query (1030 matches)

From Shannon 8/19/10: meta-p retrieves the last thing you typed in the Listener. There needs to be a shift modifier on this to go forward in case you go too far back. Also, it replaces whatever is currently in the listener, so you can't type e.g.

(+ 3 4 5)
(+ 6 meta-p)

because when you type meta-p above, it replaces the entire line with (+ 3 4 5). MCL did this right (with meta-g) such that it did not replace what was already on the line.

From Shannon 8/19/10: Selecting stuff in the editor leaves a lot to be desired. The editor seems to get confused as to whether you wish to select the stuff between parens with a double click, or just highlight the matching parens. I (the user) am confused as to whether hitting <enter> after such will actually execute the s-expression or not. [can't reproduce this today. Might have been fixed.]

See e-mail thread below for suggested improvement.

Yes, (save-application ... :prepend-kernel t) does the trick.

Doc could be improved.  The documentation for function save-application (http://openmcl.clozure.com/manual/chapter4.9.html#Saving-Applications) no information about prepend-kernel nor any other of these keyword args:

 (purify t)  impurify  (mode #o644)  prepend-kernel

The text of this chapter leading up to the function does, in retrospect, explain the wonders of prepending the kernel in a somewhat chatty and roundabout style while managing to never actually refer to the PREPEND-KERNEL arg by name.

Thanks!
