Command Link

I wrote PRCommandLink to enable a link to a command to be inserted into
a document like so:

*Logout>command:PULogout*

I remember seeing something in more recent pier's that would/may provide
this functionality, but I cant remember what it was.

I have just found PRCommandWidget (which I wrote, but was hiding in the
Pier-Seaside category) I have exported it to pieraddons, and offer it as
a potentially useful addition to Pier-Seaside.

To logout put a link like this in your environment or into any other page:

    *Logout>.|command=PULogout*

To browse the contents of the news page add a linke like this:

   *Browse Parent>/news|view=PUBrowseComponent*

To add a link to edit the root page (if you have the necessary permissions) use:

   *Edit Root Page>/|command=PREditCommand*

etc.

I don't see how this is different to the PRCommandsWidget, except that
it is only able to display a single command?

That's true, indeed. But you can with the links.

The links. It is a long existing and under-documented feature. It has
recently seen new popularity with the the value-links:

It might be an idea to re-architect commands to work on a #model, rather
than themselves. The majority of commands could return #model ^ self ,
but this would allow a command to work on an externally supplied model.
For example "Edit User Account", could be applied to some custom defined
user account model as described by magritte.

Is there a value link option to display structure settings?

For example, I have a PRPierFrameAdmin, which displays using the
original pier look, but it is themable, you can set the color and icon
of the header. Currently these settings are accesed through a special
component for the task.

And it has the option to display the link to the command as a button.

perhaps we could add | display=button for links in general.

Any description that has #displayName: set can be used as a display
setting. See the senders of #displayName: in PRStructure and
PRContext.

The parameter 'display' should be only used to define the display
string, but we could add another parameter to render as a button.
However I think this is rather problematic, because we would need to
put a form around it. I prefer to keep it as a link and define the
look using CSS, as this is normally done with all parts of Pier. Btw,
there is also the paraemter 'class' that allows you to set a specific
CSS class on the generated anchor tag.

Another mini addition - I also define

MAPluggableAccessor>>#dummy

    ^ self read: [:model | ] write: [ :model :value | ]

Until the command returns, it returns to the header context, not the
original one. Is there a workaround, or is it back to PRCommandWidget

Yeah, that's a problem. The '.' refers to the containing structure of
the link. In most cases this is what you want, but not in this case.
I'll think about this one.

As a workaround use '.' instead of '/'.
