"Every thing has its own flow"

Re: [Pharo-users] Bug? in Filein

[José Comesaña]

I see. But WATestError it is in the same package it is "Fileing", on line
3284 and is referenced many times before. I am sorry I have not enough
knowledge about the internals to do more debugging.

Seems to be a lack of coordination between FileOut and FileIn. Maybe
nothing to do...

Now a simpler and clearer test:

1. Back to the original situation.
2. FileOut *only* WAContextTest. It has a comment: "I am the base class for
all tests that need a WARequestContext present.", in .st file in line 8.
3. Remove it.
4. FileIn again. No errors on Transcript BUT no comment appears for
WAContextTest.

Maybe, if I get a couple of free hours I could dare to debug a little

Best

Re: [Pharo-users] FFI structs

[stepharo]

Ronie is working on unifying all the api and proposing one syntax 
mechanism for

- nativeBoost back-end
- FFI
and may be Alien

The FFI situation is not good and we know we should improve it.

Some of the comments might still hold. For the /time: ’05:45’/ code to 
work, you would need FFI to handle all the hassle of memory management 
and actually allocate the memory for 5 characters and copying it. I 
never used FFI but I doubt it does this.


Looking at FFI library, you both have ExternalAddress (for the struct 
with char*) and ExternalType (for the struct with char[5]) that you 
can use. For the later solution, it still looks like you should define 
a specific 5 bytes ArrayOf5Char type.

Re: [Pharo-users] AST tokens question

[stepharo]

this one is in SmaCC. I'll see if I can switch to your solution.

I had a look at Nautilus add protocol for fun. 2303 entries for a 
subclass of MorphTreeModel :( I reduce that to 11 entries in 
AltBrowser add protocol for the same use case.

:(
Same feeling here but we will live with it for now.
I started to change to the feel of the pop up.

Re: [Pharo-users] Bug? in Filein

[stepharo]

It says that the class WATestError is not available.




Yes, I did. It is in the .st file

c. You get a bunch of errors in Transcript while filing in

No magic ball so we cannot guess.


Example of Transcript messages (in case it helps):
WADocumentHandlerResponseTest>>createAndVerifyBinaryDocumentNamed:hasAttachment: 
(WATestingFiles is Undeclared)


WAExceptionHandlerTest>>testCommaReturnsExceptionSet (WATestError is 
Undeclared)


WAExceptionHandlerTest>>testCommaReturnsExceptionSet (WATestError is

WAExceptionHandlerTest>>testCommaReturnsExceptionSet (WATestError is

WAExceptionHandlerTest>>testCommaReturnsExceptionSet (WATestError is 
Undeclared)


WAExceptionHandlerTest>>testInternalError (WATestError is Undeclared)


It happens in more cases. I just took this one because this is a 
package anyone can install in order to reproduce the problem.

Re: [Pharo-users] nautilus plugin documentation

I'm going over the plugin code and hierarchy and I will probably clean 
it a bit and publish real class comments.
I'm checking the plugin to see the ones that are working and the one we 
can remove or fix.

Re: [Pharo-users] nautilus plugin documentation

[stepharo]

Here is what I found.
I'm adding a doc into book garage (pharo for the entreprise)

How to create Nautilus-Plugins

Here we will give some brief explanations on how to create your own 
plugin. By the way there are only two requirements

to create a Nautilus-Plugin:

• the class should inherit from AbstractNautilusPlugin
• it should implement #registerTo: aModel

Announcement subscription

The method registerTo: is used by the plugin to register itself to 
aModel announcements.



Pharo by Example

MyPlugin>>registerTo: aModel

aModel announcer
on: NautilusKeyPressed send: #keyPressed: to: self


In this example, the instance of MyPlugin subscribe themselves to 
NautilusKeyPressed, and

tell aModel’s announcer to send: keyPressed to the instance.

Pharo by Example

So each time a key will be pressed in a Nautilus window the 
methodkeyPressed: will be called.


Pharo by Example

Display

If you want your plugin to add a graphical widget to Nautilus you should 
override the display method.
This method should return the Morphic element you want Nautilus to 
display. By default the method returns nil to

notify Nautilus not to display anything.

Pharo by Example

MyPlugin>>display

morph := LabelMorph new contents: '';
enabled: false; vResizing: #shrinkWrap; hResizing: #spaceFill; 
yourself.


^ morph


Pharo by Example

You can also redefine the following methods on the class side:

• #defaultPosition : defines the default position of the morph (pos- 
sible values are {#top, #middle, #bottom, #none}). The default value is 
#none.


• #possiblePositions:answersacollectionofthepossiblepositions the widget 
could adopt.


And finally you could redefine the name method to change the name 
displayed in the Nautilus Plugin Manager.
