Re: [Pharo-users] why are Help topics in the meta-side

In the end it is probably a matter of conventions. Instruction how to construct something (e.g. Spec) / configuration information / descriptions / help information / examples are kept on the class side. HH On 10/3/17, H.

Re: [Pharo-users] why are Help topics in the meta-side

by H. Hirzel

The information for a help topic on the class side is used to create a help instance. Even if I technically create several instances of a particular help topic with information taken from the class side conceptually I have only _one_ help topic. The instances all share exactly the same content. Maybe the idea of 'Uniclass' (Etoys / Squeak') though not exactly the same may help. "UniClasses are classes for the instance specific behavior of just one instance." http://wiki.squeak.org/squeak/2402 In Smalltalk I always have to deal with classes. A class is an object as well. Good to keep information for cases where I do not care to have different instances with different state.

This is as if you would ask why are specs on the class side? You may actually see Help information as 'meta information'. It is information about .... The content is only needed once per topic.

Re: [Pharo-users] Iceberg and proxy

Yes, I already done that. I am behind a NTLM proxy, so I set up a cntlm proxy and configured Pharo settings accordingly. It is working because I can use Zinc directly, but Iceberg cannot pull/push. I tried the same at home without a proxy and I could not pull/push either, so it probably has nothing to do with the proxy. I will investigate moreâ¦.

why are Help topics in the meta-side

by Peter UhnÃ¡k

All help topics (subclasses of CustomHelp) have all the content on the class-side. This seems very weird to me, because the class-side should about managing the meta, not containing the content itself. It feels weird. Peter

You should probably set the proxy in the Pharo settings. Pharo does not recognize the system's proxy (so far). Could you try with that?

Re: [Pharo-users] Spec "bindings"

Hi rob we are discussing in Peter and reading your solution. Now about your example, I think that the Presenter >> subject: aDomainObject subjectHolder := aDomainObject asValueHolder We should not have countHolder in the domain object. In the domain object we should only have the domain and no value holder. Now to access a part of a domain object to refresh/change it without changing the whole, we should have something similar to AspectAdaptor in VW. What do you think?

Re: [Pharo-users] Pharo 7 license question

by Jimmie Houchin

Good and valid questions. Primarily consumer side. I am a longtime user of Linux, 20+ years. I prefer and advocate for open source software even when required to use Windows/Mac. So in general in personal life with friends, family, acquaintances if the subject is computers or software and the opportunity is reasonable I will advocate for open source software. Many times simply as an opportunity to educate people who may not know or be misinformed. I am a business man, an employee of a company. My employer is purely a Windows shop. No development is a part of my day job. All of my use of development software is personal projects. I have not released any software. Nothing has reached a point to release. I am however wanting to release a couple of projects this next year. One I hope to make money off of the use of and not the sale of. The other is personal, not business software. I hope to have both in a releasable state sometime in the next 6 months. My problem has always been indecision on what I thought would be the best language for the project. I have always loved Pharo/Smalltalk. But sometimes I explore other languages. Sometimes because they already have libraries and bindings that would make the project easier. This is still a very reasonable possibility. I am not a professional. I only program in my spare time. Due to my job, sometimes that is very little. Regardless, the software I hope to get to a releasable stage I do plan on releasing as MIT. It is the license I prefer and believe in. One need not program or release software in order to be an advocate. I have no problem with someone writing closed source software. That is their personal or business choice. Myself, I have spent way to much money on software which was closed source and the company disappeared or changed directions. Then I am stuck with software that has no future.

I have a script /pkg/pharo5vm/gopharo: #!/bin/sh PHAROVMPATH=$(dirname `readlink -f "$0"`) LD_LIBRARY_PATH="$PHAROVMPATH" exec "$PHAROVMPATH/pharo" $@ & On desktop, I start Pharo using gopharo. On server, I use daemontools. Say my application directory on the server is /pkg/app1. Here's the daemontools run file /pkg/app1/run: #!/bin/sh /usr/bin/setuidgid app1 \ /pkg/pharo5vm/gopharo -vm-display-null -vm-sound-null smallcms1.image --no-quit The other files in /pkg/app1 are PharoV*.sources and the application image/changes files. /pkg/pharo5vm contains the pharo executable, vm-*, and the *so* files/symlinks that come with Pharo plus any others that I custom build myself such as libsqlite3.so and libshacrypt.so.

Re: [Pharo-users] Testing a Unicode Character's Category

by Richard Sargent

Andrew, I've tried to comment on the changes. Overall, it was essentially what I was envisioning. My comments on a few methods are mostly specific quibbles about the implementation. One reflects that I think the original implementation contains an error. Thanks for doing this! On Sun, Oct 1, 2017 at 7:10 AM, Prof. Andrew P.

Re: [Pharo-users] Pharo 7 license question

Jimmie, Since you started this thread, I have to ask. You say you are an advocate of open source software. OK. But are you just on the consumer side or also on the producer side ? In other words, have you written/published/supported any non-trivial open source software ? Are you an academic or are you involved in commercial software (i.e. have you written closed software that you sell or otherwise make money off) ?

Hi Steven, What you see is not Bloc's cursor (there is no cursor in bloc) It is a Morphic cursor :) Cheers, Alex On 2 October 2017 at 22:19, Steven Costiou <steven.costiou(a)kloum.io> wrote: > Hi, > > i've been playing with bloc, and i am trying to completely remove the > cursor (i.e. always display a blank cursor).

Hiding the cursor in pharo and/or bloc

by Steven Costiou

Hi, i've been playing with bloc, and i am trying to completely remove the cursor (i.e. always display a blank cursor). I can't find how. Removing the Pharo cursor would also be ok, but i can't either. I can only show a blank cursor for a few moments but after moving the mouse too much it becomes normal again. I have tried: Cursor currentCursor: Cursor blank (seems not to work ?) Cursor blank beCursor (works for a few moments only...) Any way to do that permanently ? Steven.

No I have not. I don't tend to go their direction very often. I am an advocate of open source software but am not a fan of FSF's ethics or political opinions.

Re: [Pharo-users] Iceberg and proxy

by Vitor Medina Cruz

git push via command line works fine. When I try to pull, for example, from Iceberg it says "a connection with the server cannot be estabilished". I am using a cntlm bypass proxy with loggin on, and Iceberg is using it, but it fails while normal Zinc usage is ok. I will try to understand better what is happening....

Re: [Pharo-users] Pharo 7 license question

by Jimmie Houchin

Thanks for the reply and the link. Reasonably informative, but unfortunately not as definitive as one would like. What a mess. Makes me really appreciate the permissive licenses. No headaches. :) I was just curious if that was an option. Fortunately I believe I have alternatives to what I was looking to do. So I can avoid it all together. Someone posted a view by the Racket developers on their understanding of their choice of the LGPL for Racket. It seems that they are switching to MIT/Apache for Racket 7, the next version. They had all contributors sign agreements to the relicensing. https://github.com/racket/racket/issues/1570 https://groups.google.com/forum/#!msg/racket-dev/FiBLEZ-fmn8/8uLTbNamEwAJ Again thanks for the lesson and help.

hi, if you have the ssh port restricted, you need to use one that is notâ¦but then, is not clear how it will work on server side. can you try if you can do command line git push in your project?
