Re: [Pharo-users] How to view hierarchy of multiple classes in a package?

Changing ClassWidget>>#showHierarchy to: showHierarchy: aBoolean | all | (showHierarchy := aBoolean) ifFalse: [ ^ self ]. all := IdentitySet new. model selectedPackageGroup asNautilusSelection classes do: [ :cls | all addAll: cls allSuperclasses; addAll: cls withAllSubclasses ]. self cachedHierarchy: (SortHierarchically buildHierarchyForClasses: all) Will make the hierarchy button show the tree for all classes in that package/tag.

This seems to have generated a bit of conversation which has helped me quite a bit. Denis, your picture has made me realise that the System browser is a bit better than I realised. However the example I was looking at was a package that had a series of Announcement subclasses, AND what wasn't obvious was that they were all subclasses of the same parent "Announcement", as that isn't shown - you just get a series of classes not rooted under some parent (even if it was object). I'm guessing that just things that are subclasses of each other in the same package are shown? I was hoping that pane might show - Announcement + A + B + C I'm now wondering what it will show if you had a few different subclasses of the different collection classes (ok it's a bad idea to subclass them, but my point is if you had a few models at different points in a hierarchy)? I'm guessing you would see the same flat list - but I will go and try that to help me learn a bit more. Tim

[NeoJSON] creating custom maps
by sergio ruiz Feb. 1, 2017

Feb. 1, 2017

Okay, I am having the worst time with this.. i have a class called RadioStation that for now, just had Â few text instance variables. all I really need to do is turn this into JSON.. i can do it with something like: String streamContents: [ :stream | Â Â (NeoJSONWriter on: stream) Â Â Â prettyPrint: true; Â Â Â mapInstVarsFor: RadioStation; Â Â Â nextPut: (RadioStation SelectAll last) ].Â Â Â Â Â but this seems like massive overkill.. plus, very soon, this is going to have collections of other objects.. also, since this returns a string.. when Teapot returns this, it escapes all of the âs and produces illegal json, as itâs just a string.. i read about mappers, but i canât figure out how to create them.. doing something simple like: | mapper server | mapper := NeoJSONMapper new. mapper mapAllInstVarsFor: RadioStation. mapper mappings. NeoJSONWriter toString: station. which feels like it should work, gives me: No mapping found for RadioStation in NeoJSONWriter any help? thanks so much! ---- peace, sergio photographer, journalist, visionary Public Key:Â http://bit.ly/29z9fG0 #BitMessageÂ BM-NBaswViL21xqgg9STRJjaJaUoyiNe2dV http://www.Village-Buzz.com http://www.ThoseOptimizeGuys.com http://www.coffee-black.com http://www.painlessfrugality.com http://www.twitter.com/sergio_101 http://www.facebook.com/sergio101

STON encoding of slashes
by Christophe Demarey Jan. 31, 2017

Jan. 31, 2017

Hi, I just noticed that STON encoding of forward slashes changed. STON toString: 'git@github.com:foo/bar.gitâ => ''git@github.com:foo\/bar.gitâ' It used to be ''git@github.com:foo/bar.gitââ. Is it on purpose? Thanks, Christophe

Reliable way to persist graph of object
by Hilaire Jan. 30, 2017

Jan. 30, 2017

Hi, I already reported here the main problem of Fuel, no upward compatibility among Pharo version. It is a bit pathetic as it nullified a lot the interest of Fuel. Fuel in itself is really great, so it makes this situation even sadder. Phratch is another victim of this problem. Phratch users can't load their projects on newer version of Phratch (newer as based on newer version of Pharo). An option could be to stick Phratch releases to one specific version of Pharo. But not ideal. So all in all what are the options we have to persist reliably and with compatibility a graph of objects. Thanks Hilaire -- Dr. Geo http://drgeo.eu

Pharo not opening my image automatically
by Dimitris Chloupis Jan. 30, 2017

Jan. 30, 2017

Hey guys, I have a makefile that downloads Pharo with curl get.pharo.org/alpha+vmLatest | bash I then move pharo.app from the pharo-vm subfolder to the parent folder that contains my Ephestos.image , together with Pharo50.sources the problem is that when I double click on it instead of opening my image automatically as Squeak used to do , it does not and instead it prompts me which image to choose even though there is no other image in folder and no other changes file (Ephestos.changes) Am I doing something wrong ? Should it not open the image automatically without asking me ?

I'd really love to use Pharo this way
by Jose San Leandro Jan. 27, 2017

Jan. 27, 2017

Hi, I've come across this new attempt to bring Literate Programming to the masses. http://www.witheve.com/ It all seem to come from Jupyter Notebook. I'd love to build something like that in Pharo, but I currently lack the skills needed. Any suggestions on how to start? Would you use Seaside, Pillar, ...?

Bad Request ZnEntityTooLarge
by Bernhard Pieber Jan. 26, 2017

Jan. 26, 2017

I have a Seaside application which includes a file upload feature. renderContentOn: html â¦ html fileUpload callback: [ :file | self receiveFile: file ]. html submitButton: 'Uploadâ ] â¦ In receiveFile: I just save the uploaded file on the file system. When I upload a file larger than 16 MB an error page is shown with the error message: Bad Request ZnEntityTooLarge I found that by using ZnConstants>>maximumEntitySize: I can increase this limit. However, I want to catch this in the image and show an error message to the user. I tried wrapping receiveFile: and renderContentOn: with an on:do: exception handler for ZnEntityTooLarge. However, neither works. It seems that the error happens before renderContentOn: is even called. I searched the mailing lists but did not come up with an answer. How can I achieve this in Seaside? Any help would be much appreciated. Cheers, Bernhard
