Hello Peter,
If your are on Moose, you are using the Glamour inspector.
Can you describe more precisely the kind of items you are inspecting? Do you inspect external resources? Or use Semaphores, forks, network?
I am remembering a bug on Roassal. It used external ressources that was desallocated at image shutdown. On image relaunch, the external ressources was still pointed by a cache and the yellow cross on red appears.
By the way, behind the cross, it should be a text, can you see it?
I know that these kind of issues are very difficult to reproduce but if you can do it on a fresh image, it will be easier for us to help you ;)
I cross-posted to the Moose mailing list where people are more aware of this kind of issues.

I am not sure, but I think Moose uses the Glamour inspector. You get exactly the same inspector whether you select ‘Inspect’ or ‘Explore’ from the world menu. As you click on an item in the current display, a new inspector pane opens to the right showing detail of the selected item, with tabs to select the form of display – the first one is always ‘Raw’ but the others are dependent on the kind of item being displayed, e.g. if inspecting an XML document there is always a ‘Tree’ option. I think that sounds like Glamour, doesn’t it?
The main heading on the title bar is static, i.e. it always shows the item you originally inspected. When there are multiple inspector panes open, each one has its own title below the main window title, showing the item that was clicked to open it. In this case, the title of the first inspector pane, which is the same as the main window title, is also replaced by the red error display, but the titles of the other inspector panes are OK.
Hope this helps. If any more detail would be helpful, let me know.
Thanks

Hey,
Inspectors are different between Moose and Pharo 3. Can you precise, are you using the Glamour inspector, the EyeInspector or the old Morphic inspector ?
I have never seen that in Pharo. Are your titles dynamic (I mean, when the object changes, can your title change ?) ?

Hello
I am using Moose 5, which is essentially Pharo 3, downloaded late December 2014. I have a development project which mainly consists of a collection of workspaces and inspectors (I really do intend to turn it into a properly structured set of classes one day!). I have noticed that, whenever I save an image with some inspectors open and then reopen the image, the title bars of the inspectors have become red rectangles with a cross superimposed. Often I can work out what the title should be and carry on, but in many cases all I can do is close down the inspector and reopen it. Is this a known problem, and is there any way to work round it?
Thanks for any help
Peter Kenny

I’ve switched content of "zoom in" and "zoom out” icons in Glamour-Morphic-Theme-YuriyTymchuk.200. Before that when you’ve pressed on a magnifying glass with “+” sign it zoomed out, and this was awkward.

Hello
We use Roassal 2 for visual side of a project we are working on - a
diagram modelling tool (like enterprise architect) and we came to a
specific need. There are notations like UML which need heads/arrows on
both ends of a single line.
As far as I understand the roassal code, line decorations are encoded to
be at the "to" end and can't be on the other one.
We would use help with this problem.
Thanks

Hi,
the jenkins slaves are offline again.
I’ve resurrected the moose ones, but I don’t have rights to manage pharo-contribution. Can someone do that please?

OK, try making a proposal then, http://gsoc.pharo.org has the instructions and the current list, you probably know more about data science than I do.

Well, you are certainly free to contribute.
Heuristic interpretation of data could be useful, but looks like an addition on top, the core library should be fast and efficient.

These libraries (NeoCSV, NeoJSON, STON) were all written with only a dependency on a limited character stream API. It was a design decision not to depend on a File API, because at the time we were transitioning from the old FileStreams to FileSystem.
And I disagree about the JSON introduction ;-) You might know it, but that is not the case for everyone. Like not everyone knows CSV, HTTP, ...
But I do agree that sometimes I too would like a convenience method here or there ;-)

Both NeoCSV and NeoJSON can operate in two ways, (1) without the definition of any schema's or (2) with the definition of schema's and mappings. The quick and dirty explore style is most certainly possible.
'my-data.csv' asFileReference readStreamDo: [ :in | (NeoCSVReader on: in) upToEnd ].
=> an array of arrays
'my-data.json' asFileReference readStreamDo: [ :in | (NeoJSONReader on: in) next ].
=> objects structured using dictionaries and arrays

GT Tools are awesome!!! I'm molding some inspectors right now ;)
Two things...
Bug (I think):
1. Type in Playground: "1 printString"
2. Place cursor between "print" and "String"
3. PrintIt
4. Press enter to paste PrintIt as comment
-> The comment appears at cursor position. I encountered this when I clicked
at a random place in the selector to move the cursor to that line to
PrintIt. At minimum, if nothing is selected, IMHO it should paste the
comment after a word boundary, if not at the end of or line - not sure...
Suggestion: now that Pharo 4.0 has horizontal scrolling, it would be
interesting to scroll between the Miller Columns of the Playground that way
(if a scrollable panel doesn't have focus)

Cheers,
