[Pharo-users] Removing contents-changed marker from Rubric on save

[Evan Donahue]

Currently, if you add a "composite text" view using gtInspector, the editor
lets you use ctrl+s to save changes to the local inspector.

However, if you intercept ctrl+s to implement an actual save function, as
FileReference does, the text editor no longer knows to remove the
contents-changed indicator. You can see this in the current FileReference
inspector:

f := FileSystem disk / 'tmp' / 'filerefinspectortest.txt'.
f writeStreamDo: [ :s | s nextPutAll: 'test data' ].
f inspect. "Change the data and hit ctrl+s. The contents-changed indicator
is still there."
f inspect. "If you inspect again, you will see that the contents have
indeed been saved to disk."

How would I change code like the FileReference >> gtInspectorContentsIn:
code to make the content-changed indicator work properly? Who is in charge
of that indicator and how do I tell them to turn it off?

Thanks,
Evan

Re: [Pharo-users] [ANN] Python3Generator and MatplotLibBridge

[Kjell Godo]

did you use a socket to communicate from Pharo to Python?
 it does not sound like it it sounds more one way
 i am interested in using sockets to communicate between programs
  but i haven't done much with it yet
 maybe you can include sockets in your generated Python to talk
  back to Pharo ?
 i got Dolphin Smalltalk to talk to Pharo using a socket
  but i kind of forgot about it
did you look at Roassal ? Roassal does a lot of plotting they look very nice
 they have mouse interactions and lots of cool stuff
  but i don't know how they relate to other plotting programs
 i imagine that Roassal tries to do things not done in other programs
  but i don't really know i looked at some other plotting thing
also
  can't remember Sci something
 Roassal has a nice declarative style that is nice
  i want to use it a lot in future
  i use Roassal in the Moose Pharo image because it is pre installed
i have a rich text tree editing program in Dolphin Smalltalk
 that i use like a note taking program like everNote but as a great big
tree
  using the old Windows tree widget in Dolphin 6 which i like
  and i store a lot of my text stuff in there
 and i would like to store and edit Racket programs or lisp programs
  in there in a tree format
 and your project sounds interesting
  about how to maybe generate Racket code that will allow
  me to use Dolphin and Pharo and other Smalltalks as a front end
to
  Racket or commonLisp etc
  because i don't like the GUIs or IDEs of those things
   ( they're so primative )( but i don't know them well )( they
just look
brittle )( and C like )
 and i believe there is a command line interface in Pharo so you can
  execute external programs like generated scripts

Thank you, Pierce

I got similar ffi exceptions when I call

Gofer new

  smalltalkhubUser: 'PharoExtras' project: 'ODBC';

  package: 'ConfigurationOfODBC'; load.

  (Smalltalk at: #ConfigurationOfODBC) load.

Not Squeaksource. Load the version from Smalltalkhub:

  Gofer new
smalltalkhubUser: 'PharoExtras' project: 'ODBC';
...

Hopefully this version works with or without Esteban's suggestion.

> I still don't see how postgres can help but I'll give it another try.

I suggested PostgreSQL FDW because I know PostgreSQL. If you are not familiar
with PostgreSQL, then setting it up, setting up its FDW, and finally setting up
programmatic access to PostgreSQL to get at the FDW data is probably more work
than it is worth.

It depends. I wanted to customize the process a bit, and avoid that some
people make gifts to some specific people.

Re: [Pharo-users] Formatted print for Duration

[Julien]

I chosen something like the second solution to avoid adding a dependency to my 
project (it is a bit overkill for what I wanted to achieve). But shouldn’t this 
formatted-print feature be added in Duration?

Re: [Pharo-users] Solver for the Stable Marriage problem in Pharo

[Julien]

Not sure you can use it for that.

I mean, you wanted random pairs of people no?

So no need to rank people according to some preferences?
