Cool! I set it up so that each time people commit it will build automatically. Now alex did not commit anything yet but it would be great to have something about your approach. Here is the link https://github.com/SquareBracketAssociates/Booklet-IA-Neurons I can give you commit rights.

Re: [Pharo-users] Generate equality

Noury proposed a traits for that long time ago and it looked smart. I do not remember where.

Re: [Pharo-users] Pillar script evaluation generating a screenshot

by Stephane Ducasse

Hi Juraj I do not know it on top of my head. I will check ... For example you get a stream in which you can work [[[eval=true stream nextPutAll: '__WfManagedObject comment:__ ' ; nextPutAll: WfManagedObject comment; cr; lf. ]]] Now I would like to get automatically some png.

Re: [Pharo-users] Generate equality

by Herbert VojÄÃk

This does not look like the answer to my question. :-/ Ok, to rephrase: Would you find it useful to have "generate equality" which generates #= and #hash for a class? Herby P.S.: I know there is "generate accessors". I mentioned it as "a thing which is there, and from which one can get inspiration".

Re: [Pharo-users] Generate equality

by Peter UhnÃ¡k

> generate accessors there is option to generate accessors (right click on class)... but I find it rarely useful after initial setup (having accessors for all instance variables is rarely needed, and it is annoying to uncheck all the time). In the latter scenario I have a small hack (startup script) that adds the option to instance variable (works with slot class layouts only) suggestions menu (not updated for calypso yet... https://github.com/peteruhnak/pharo-scripts/blob/master/config/6.0/suggesti… ) for initialize, Nautilus had some shortcuts to generate code which you can try https://gist.github.com/peteruhnak/d9ee54f67d88b20ba85618e189b15669#generat… Peter On Wed, Feb 7, 2018 at 5:10 PM, Herbert VojÄÃk <herby(a)mailbox.sk> wrote: > Hi! > > Do you think it would be reasonable to have, a la "generate accessors" / > "generate initialize method", a "generate equality" thingie that would > generate #= and #hash for the method, mechanically? > > Just created a new "piece of data" class and felt like it would be helpful. > > Herby > >

Generate equality

by Herbert VojÄÃk

Hi! Do you think it would be reasonable to have, a la "generate accessors" / "generate initialize method", a "generate equality" thingie that would generate #= and #hash for the method, mechanically? Just created a new "piece of data" class and felt like it would be helpful. Herby

Or do you just need to use the variant sending #value: to a > block with the morph as an argument? I am not sure if we understand each other. The example: morph := 'Hello' asMorph. morph on: #mouseUp send: #traceCr: to: morph. morph openInWindow does not work for me. Actually I have not found a code that triggers #mouseUp event neither. The example: morph := 'Hello' asMorph. morph eventHandler: MorphicEventHandler new. morph eventHandler on: #click send: #traceCr: to: morph. morph openInWindow. works well and this is what I use.
