Re: [Pharo-users] Hiding the cursor in pharo and/or bloc

by Denis Kudriashov

Hi. Look at Cursor class side. All cursor bitmaps are in class variables. If you will replace all of them with blank cursor then cursor will be always blank. Something like this: Cursor classVariables associationsDo: [ :each | each value: Cursor blank ] 2017-10-03 9:38 GMT+02:00 Steven Costiou <steven.costiou(a)kloum.io>: > Ah, thanks.

Re: [Pharo-users] Spec "bindings"

by Stephane Ducasse

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?

Nice. We should make a booklet of all this. There is also the Ansible playbook we have and the Docker story as well.

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.

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.

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) ?

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.
