Persistence on Moose browsers, showing always a selection in trees and making tree labels editable.

Hi,

With the valuable help of the community and the GLMBasicExamples I have
been able to build basic outlining interface and functionality. Here is
a screenshot:

There are some issues:

1. Now I would like to make the nodes in the tree persistent in the
sense that if I wrote something in the node body (left upper part of the
browser) and I select another node, when I visit the previous node, the
text in the body still is there. How can I do this?

2. I would like to make the current node always selected by this blue
highlighting. With some operations like moving nodes to the left or to
the right, the current node gets out of focus, despite of the operations
being done over it. There is any way to say Moose browsers where to put
the selections, besides of explicit selection with the mouse.

3. Some time ago I asked about how to make tree labels (headers), at the
left of the browsers editable. There is any way to make this?

Thanks a lot,

Offray

Hi Doru, Sven and community,

I have made a small experiment to get persistence on browsers by using
STON. I really like the readability of STON. At [1] you can see a screen
shoot of a moose browser tree and attached to this mail is equivalent
STON file.

I have some questions, nothing with code because they're kind of general
and not referred to any particular code written at the moment. Any way
if someone want to see the code and load the browser, here is what needs
to be done:

Gofer new
     smalltalkhubUser: 'Offray' project: 'Ubakye';
     package: 'Ubakye';
     load.
UbakyeBrowser open.

Here are the questions:

I would like to capture some events that happens in panels. For example,
suppose I write a text in the "Cuerpo | Body" panel and I would like to
get the body of my node updated with what has been wrote on the panel. I
have seen "Populate port action" example, but it works on selection and
I would like to update the tree anytime a body panel is wrote, without
any particular selection and also the "updateOn" message, but I don't
know if this is the proper message to use when the user is just writing
in a text panel of a moose browser. How can I updating on writing in a
text panel can be done?

Also, how can I create an emergent window (similar to the inspector
example that Doru gave to me) but just with the current name of the
header of the node, and also made that the node header updates on
clicking "Ok" button of that emergent Window?

The last question its related with Sven's STON: Suppose that I would
like to store light markup languages in STON which have the single quote
character (') on them, without creating any escape sequence, is this
possible on  STON and if not, what is needed to be changed for that?

Thanks,

I am not sure I understand, but I assume you want to be able to write another language inside a String constant. STON uses the same escape sequences as JSON. So that means you have to use either the general \uFFFF or a couple of shortcuts, like \' and \". Note however that you can use both single and double quote as string delimiters.

So you do:

'x:="foo"' or "x:='foo'" as well as 'x:=\'foo\'' and "x:=\"foo\""

Does that help ?

Hi Sven,

Yes I imagine myself writing long structured documents in light markup
languages (specifically pandoc's markdown [1]) in my outliner and
storing it in STON. Because single and double quotes are fairly common
in writing I would like to write my documents with out worrying about
escape characters or the sequence of single quotes and double ones.
Being STON a young language would be nice to provide a way inside it to
store arbitrary long sequences of text that can contain single and
double quotes.

YAML[2] (another nice serializing language) has solved the issue with
indentation blocks and some minor marks which help a lot to human
readability (similar to the pretty printing of STON) and python has
their triple quotes which are pretty uncommon on casual writing. Both of
the has proven to me being very useful ways to store light markup
language inside yaml or python and I would like to know if there is a
similar option for STON or if this can be easily implemented.
