I'm trying to create a value link that can display a single command inside a document.
But I struggled to create a proper link for the command. This seems only possible if you
have a pier context and renderer at the same time which is not really the case as long as
you are staying inside PRValueLink.
The only solution I could come up with is the following:
PRValueLink>>commandIn: aContext
<value: 'command' comment: 'Display command as link'>
(PRCommand withAllConcreteClasses
detect: [ :each | each label = (self parameterAt: 'label' ) ]
ifNone: [ ^ nil ])
ifNotNilDo: [ :commandClass |
^ [ :html |
html anchor
goto: (aContext command: commandClass new);
with: commandClass label]].
^ nil
I have the impression there might be a solution without using a block. Any ideas? Or is it
ok the way it is?
thanks,
Norbert

Actually this is already implemented, for example:
*value:structure|link|command=Remove*
Also works with all other value-links that list or return structures,
e.g. children, references, parent, previous, random, siblings, find,
...

And in fact you don't need to use a value link for triggering a
command, a normal link with the command parameter is enough:
*/some/page/to/edit|command=Edit*
Note that in both cases this goes through the security system.

Ok, everytime I think I have a useful idea it is already there and better
implemented :) It is nice that I can do it either one or the other way. But the link text
is always the title of the target structure. I need the link label to be displayed. In the
second approach can do it manually with *Label>/some...* (does not work with the first
approach *Label>value:...*. Is there a way to display the link label?
thanks,

ValueLinks only display the label when they are undefined. Otherwise
they display the default string of the target (e.g. the title) or
whatever display parameter (this is the name of a description on the
object) is set.

+value:commands+ displays all the available value links because it
displays all selectors of methods that have the proper <pragma> in them.
You're talking about displaying the options available for a specific
value link and there's no built-in mechanism for that. You'd have to
provide it yourself. You could request all parameters for +value:xxx+
that was passed to the >>xxxIn:contents method, but that would only
give you the parameters/commands that are specified in the text of the
link. If you want to provide a list of all possible options, you'll have
to define one yourself:
+value:myValueLink|command=displayAll+ and from inside method
label to
be displayed. In the second approach can do it manually with

So proper use would be:

Assuming that we extended>>contentsIn: in some way...
Is there a difference between using '+' and '*' in the context of value

Yes, look at the senders of #hasParameter:, #parameterAt:,
#parameterAt:ifAbsent:, #parameterAt:ifPresent:, etc.

In fact the method can ask #isEmbedded to itself to know. This was
currently done using the parameter 'embed', but I changed it in the
latest version which makes more sense.
