[Pharo-project] package renaming
by Pavel Krivanek Sept. 26, 2011

Sept. 26, 2011

Hi, do we have some experiences with renaming some of basic system packages in the update stream? Because we will need to rename Morphic package to something like Morphic-Core or so to enable the next Morphic package splitting. Cheers, -- Pavel

[Pharo-project] Class creation notification
by Mariano Martinez Peck Sept. 25, 2011

Sept. 25, 2011

Hi guys. I was checking who needs to be notified when a class is created. If I follow correctly senders of #notify:ofSystemChangesOfItem:change:using: and friends, I don't really find too many listeners. I found TestRunner >> initialize and MCPackageManager -- Mariano http://marianopeck.wordpress.com

[Pharo-project] Fraction>>asFloat needs review
by Nicolas Cellier Sept. 25, 2011

Sept. 25, 2011

After Integer>>asFloat, Fraction>>asFloat needs a review too. It is not broken. But it has unreachable code, performs more arithmetic than necessary and we could put some light on obscure comments and reduce implicit knowledge. So if we can leave a better example of coding in the image, let's do it. It's better to write this in a Blog http://smallissimo.blogspot.com/2011/09/reviewing-fraction-asfloat.html because it would be too long for a single commit comment. Nicolas

[Pharo-project] looking for boring morphs
by Esteban Lorenzano Sept. 24, 2011

Sept. 24, 2011

Hi, I have a customer who are asking me for a very small app... but a desktop app, not the usual web app I'm more used to do... and of course, I'm doing it with pharo! So far... this is working really well... much easier as I supposed it would be :) I'm using glamour, magritte, keybindings, hpdf, mongodb... and small tweaks by my self to make it work as expected, but not so much. (btw... I want to say that a couple of years ago, this wont be an option at all... this is due to the great effort the pharo community is doing, and I'm really proud of it. Thank you guys!) well... now... I need some morphs a regular management application usually needs: 1) NumberInputFieldMorph (A child of TextMorph or PluggableTextMorph who allows different kind of numbers -> this is easy to do, but better if it is already somewhere) 2) DateInputFieldMorph (a morph with a "date picker" -> this is harder, because I have very limited knowledge about morphic) 3) I'm sure there are others I didn't needed yet, but there are needed in this kind of applications so... does someone has this kind of morphs somewhere? I would really appreciate it, because you know... it is doable, but time is tyrant and better if I can reuse someones work ;) cheers, Esteban

[Pharo-project] image persistency does not seem to work
by Tudor Girba Sept. 24, 2011

Sept. 24, 2011

Hi, I am testing the latest Pier2 based on Pharo 1.3, and I got an error when trying to use the image-based persistency. The error happens in: PRImagePersistency>>saveImageAndBackupAs: aString ... image openSourceFiles; saveImageSegments; snapshot: true andQuit: false in particular, the SmalltalkImage does not understand saveImageSegments anymore. Is this some cleanup that happened in Pharo and that requires a new package to be loaded? Cheers, Doru -- www.tudorgirba.com "To utilize feedback, you first have to acquire it."

Most of ImageSegments is there (and even cleaned and fixed by Mariano while he analyzed the code). We removed all of ImageSegment code in the image in 1.4, though. After *very* careful analysis *and* implementing a better replacement... (Fuel). The #saveImageSegments when saving the Image itself I removed in 1.3 already (after sending a mail to the list to ask if anyone uses it). The idea was that on image save, if image segments are written to disk, it would copy them over if you rename the image on save: saveImageSegments: previousFullImageName "This method is used for example when you save an image with another name. In this case, if there are segments written to files and there are ImageSegment instances, then it copies the file from the previous image location, to the new one. It is like a backup of the segment files when renaming an image. " | haveSegs oldImageSegDir theClass newImageSegDir | "If the class does not exist or has no instances, it has no sense to backUp the segments." self areThereImageSegments ifFalse: [ ^ self ]. theClass := Smalltalk globals at: #ImageSegment. oldImageSegDir := theClass segmentDirectoryFrom: previousFullImageName. newImageSegDir := theClass segmentDirectory. "create the folder" oldImageSegDir fileNames do: [ :theName | | imageSegmentName "copy all segment files" | imageSegmentName := oldImageSegDir pathName , FileDirectory slash , theName. newImageSegDir copyFileWithoutOverwriteConfirmationNamed: imageSegmentName toFileNamed: theName ] So if your image has no image segments, than it's ok to just remove the call.
