Re: Org, Hyperbole, and eev

[Robert Weiner]

That was not the offer.  The offer was to show you how to implement a discrete eev command using another framework, possibly simplifying its implementation.  Hopefully, from seeing the code used to do this, you could dig in yourself and follow the flow to whatever level you like.  Hyperbole, for example, has been implemented across years of part-time work.  Of course, it has complexities in its implementation and if the non-abstract parts of that interest you, then use edebug or trace commands to explore the code flow but I wouldn't expect anyone to write that out for you.

#3 is closer to the offer.  If you want to see a Hyperbole function or button type equivalent, I can show you that, i.e. you load Hyperbole and then you use Hyperbole or eev syntax to jump to a point in a video that is done through a Hyperbole implementation.  But I can't explain the Hyperbole dispatching mechanisms except at a high level.  hkey-alist in Hyperbole is not hard to understand.  The prioritized list of implicit buttons types in Hyperbole is not that hard to understand.  That kind of level I can discuss.

I am not sure if I understood your proposal correctly, but let me
propose three tasks that would be pretty natural in eev-land... In all
cases below "explain" means "explain step by step, with links to the
source code and to the docs, and with sexps that inspect the data
structures".

  1) explain what happens when we type M-RET on this button:

       "subr.el"

  2) explain what happens when we type:

       C-h h d d

  3) suppose that we have a function that plays a local copy of your
     video "GNU Hyperbole - Overview and Demo". Let's use this fake
     function instead of a real one:

       ;; Test: (fake-play-oand "2:34")
       ;;
       (defun fake-play-oand (time &rest comments)
         (move-beginning-of-line 2)
         (insert (format "[Play Overview and Demo from: %s]\n" time)))

     Explain how you would implement buttons - choose your favorite
     syntax for them - that play "GNU Hyperbole - Overview and Demo"
     starting from a given timemark.

Is that a good starting point? Note the unusual meaning for
"explain"... how would you use Hyperbole to prepare these
"explanations"?

I'm very interested in seeing your suggestions! Can you be more
concrete?
