[Pharo-project] feature request - undo closed tab
by btc＠openInWorld.com Jan. 1, 2012

Jan. 1, 2012

Neglecting that in 6 months I might be in a position try implementing this myself, here is a feature request in case anyone likes it enough to implement it in the meantime, or who can advise why it is a bad idea. Background: For me, one of the greatest most useful features of web browsers is the "Undo Close Tab." I browse almost exclusively opening all links as new tabs since I find this the fastest to follow diversions and then return to my previous place up the stack of tabs. I can get 20 or more odd tabs in a browser window. When I'm speedily closing tabs to backtrack my position, I find my recognition of content often lags my tab closing by a split second. Being able to un-close that last tab is a lifesaver. Now that I am getting into actual programming in Pharo, I have found that from time to time I've ended up with more than a dozen tabs in the "task bar" at the bottom of World. A few times already when I've flicking through these closing them after finish a line of thought, I have accidentally closed some tabs that I wanted to keep - like the Workspace I had been using as a bit of a history log. Perhaps my workflow is bad - but I really miss being able to Undo closing that last window. Features: 1. For a window that has a tab on the "task bar" at the bottom of World, when it is closed allow it to be reopened in the same state. 2. Clicking on the "Task bar" provides a menu item "Undo Close Tab" that either: 2a. Brings back the last closed tab. 2b. Provides a "restore list" of previously closed tabs sorted by time closed, which brings back that tab. Implementation Idea: 3. When closing a tab, rather than actually closing it, the window is just minimised but is removed from the tab and placed on the "restore list". 4a. The "restore list" is a certain length and when a tab is bumped off the end it is properly closed. 4b. Alternatively tabs may remove themselves from the "restore list" after a certain timeout eg 30 minutes. I'd appreciate your thoughts... cheers, Ben

[Pharo-project] System Browser - shifting class comments into pane beneath class definition
by Ben Coman Jan. 1, 2012

Jan. 1, 2012

I could not find any previous discussion of this so I'll just throw this out there... I find that I forget to click the "?" button to read the class comments as I browse around the system. They are "kind of" hidden. Perhaps also I stop looking because they are often empty. If others do the same then it is a downward spiral... if it seems no one looks at them then no one values writing them. (Except for the good work of the COTDC) However System Browser opens by default with 16 lines. Most class definitions (eg [1]) use 6 lines, which leaves a lot of unused whitespace. I wonder if the class comment was to appear (in a separate pane) beneath the class definition then the class definition would be filled out more often. Bring the class comments to the fore and perhaps they'll be valued more. At least for me, it will ensure that I don't miss where there are good comments I can learn from. Also more attention may focus on the poor comments due to being more exposed. just a random thought... cheers, Ben [1] Object subclass: #Behavior uses: TPureBehavior instanceVariableNames: 'superclass methodDict format' classVariableNames: 'ObsoleteSubclasses' poolDictionaries: '' category: 'Kernel-Classes'

[Pharo-project] Possible bug in FFI
by ncalexan Jan. 1, 2012

Jan. 1, 2012

Hello all, Long-time reader, first-time poster. Is FFI fully supported on Pharo? I installed into the 1.3 OneClick using Gofer new squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfFFI'; load. ConfigurationOfFFI load. All seems fine but ExternalAddress gcallocate: 128 fails in ExternalAddress>>shallowCopy, complaining that clone is not understood. Bug? Not supported? Misused? Best, Nick Alexander -- View this message in context: http://forum.world.st/Possible-bug-in-FFI-tp4241299p4241299.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.
