Using passing the tempo-template user input to my function?

Using passing the tempo-template user input to my function?

[Hattuari]

I've tried all the ways I can come up with to pass the string returned from
querying the user to my own function.  I know the string is there, I can
paste it into the text at the point where I'm trying to paste a modified
version.

This is an example of code that pastes the original user text:

(tempo-define-template
 "array"
 '("typedef array<"
   (P "Data type: " data-type)
   ","
   (P "Number of components: 1 to 4 " data-order)
   "> Array" (s data-type)))
;;

Variations such as the following don't work:

;; this does not produce an error message, but fails to produce the intended
;; result.
"> Array" (plist-get paste-data-type-map (tempo-lookup-named 'data-type))))

;; This produces errors whether data-type is quoted or not.
"> Array" (plist-get paste-data-type-map (s 'data-type))))

If I explicitly pass the correct string to the function, the correct output
is generated.  Suggestions?
-- 
p->m == (*p).m == p[0].m

,----[ C-h f tempo-define-template RET ]
| tempo-define-template is a compiled Lisp function in `tempo'.
| (tempo-define-template NAME ELEMENTS &optional TAG DOCUMENTATION TAGLIST)
|
| Define a template.
| This function creates a template variable `tempo-template-NAME' and an
| interactive function `tempo-template-NAME' that inserts the template
| at the point.  The created function is returned.
...
| The elements in ELEMENTS can be of several types:
...
|  - The symbol 'p. This position is saved in `tempo-marks'.
...
|  - (p PROMPT <NAME> <NOINSERT>) If `tempo-interactive' is non-nil, the
|    user is prompted in the minbuffer with PROMPT for a string to be
|    inserted. If the optional parameter NAME is non-nil, the text is
|    saved for later insertion with the `s' tag. If there already is
|    something saved under NAME that value is used instead and no
|    prompting is made. If NOINSERT is provided and non-nil, nothing is
|    inserted, but text is still saved when a NAME is provided. For
|    clarity, the symbol 'noinsert should be used as argument.
|  - (P PROMPT <NAME> <NOINSERT>) Works just like the previous tag, but
|    forces tempo-interactive to be true.
...
|  - (s NAME) Inserts text previously read with the (p ..) construct.
|    Finds the insertion saved under NAME and inserts it. Acts like 'p
|    if tempo-interactive is nil.

If tempo-interactive is nil, perhaps you need to do something like

(let ((tempo-interactive t))
   (tempo-define-template ...))

which would also allow you to use (p ...) instead of (P ...) in your 
template.

The user is prompted for input.  The input is available for insertion using
s NAME.  My question is how do I use the value returned by s NAME in my own
function?

Well, at least I can refine my question based on further understanding.  My
mistake is trying to compare the string "GLbyte" with the symbol 'GLbyte. 
These are distinct objects with unrelated values.  What I should probably
be doing is providing the user with a picklist of symbols to chose from. 
Is there a way to do that?

The normal Emacs way to do this by reading it from the minibuffer with
completion.  See the function completing-read.

That's pretty much what I'm shooting for.  What I want is to prompt the
reader for a series of responses, the first being of the form 'GL<type>'
where <type> is selected from a pick list.  The next will be an integer in
the range 1 through 4. And the last value will be boolean, preferably with
some mnemonic representation indicating its meaning.  I've looked at
completing-read and completing-read-multiple.  I wasn't able to figure out
how to use the latter.  

I haven't directly revisited the topic because I want to finish reading the
preceeding sections of the Reference Manual. And because someone who's IP
address traced to a Redhat linux box in Japan discovered a way to attach to
several of my highports with ssh and gain access to my system...  I was
forced to reinstall since I couldn't upgrade from the very ancient version
of SuSE Linux I was running on the server.

I meant completing-read-multiple. I'll have to look at it again before I can
formulate any specific questions.

Perhaps the easiest method to read a boolean is y-or-n-p.  Is this
what you mean by "latter"?

Use your own query-function and a global variable. 

For example

    (defvar xyz-name nil)

    (defun xyz-read ()
        (interactive)
        (setq xyz-name (read-from-minibuffer "xyz-name? ")))

    (defun xyz-func ()
        (upcase xyz-name))

    (tempo-define-template "xyz" 
        '("xyz { " (xyz-read) " } { " 'xyz-name " } { " (xyz-func) " }" )
        "xyz" "desc" 'elisp-tempo-tags)

I just wanted to let you know I didn't ignore this.  I did look at the code
you posted, and tried a few variations.  The reason I'm exploring
alternative approaches is that I simply came to the conclusion that I need
to work on the fundamentals of Lisp a bit more.  I've been stabbing in the
dark at my .emacs for years without really understanding what I'm doing.
I've wasted a lot of time trying to accomplish 'simple' things because I
didn't know what I was doing.
