This is also my thinking it is nice to let the user explore the environment arround. I know Alain, a Pharo fan now, discocer the underlying Pharo with DrGeo scripting et al.

I ask that to see if we need to hide much of what makes a system browser in Smalltalk, or, to the contrary, if it is a good idea to open up to the browser world so as to introduce the user (maybe advanced) to the underlying Pharo so as to allow for more powerfull extensions.

Thierry, I was not aware it could be that short. Yes it will be nice. All in all: - one GUI tool to edit an existing script (so no visibility on the other methods of the class) - one GUI tool to create a method (with visibility to the other method of the class, as possible examples) Hilaire Le 15/05/2014 09:18, Goubier Thierry a Ã©crit : > Have you considered controlling the user experience directly to let him > focus only on the method to create or edit? > > Creating a text editor window in coding mode with the ability to edit or > create a method in a preset class is not much work; I'd say around 20 > lines with the default menu and an accept which compiles. > > If you want complete control on the menu (i.e. a bit more polish than > the default and control over which shortcuts are active), I can extract > what I've done for mine: it's a minimal command objects API to couple > menus and shortcuts inspired by the one of the OmniBrowser (of Pharo > 1.4).

Have you considered controlling the user experience directly to let him focus only on the method to create or edit? Creating a text editor window in coding mode with the ability to edit or create a method in a preset class is not much work; I'd say around 20 lines with the default menu and an accept which compiles. If you want complete control on the menu (i.e. a bit more polish than the default and control over which shortcuts are active), I can extract what I've done for mine: it's a minimal command objects API to couple menus and shortcuts inspired by the one of the OmniBrowser (of Pharo 1.4). In there, a typical command with its shortcut/label/icon/activation status is about five lines long. The example I showed you is a full browser, but in which all actions, refactorings and searches will be limited to the class. I still think it is a bit too much for you use case.

Re: [Pharo-users] Problem learning about Magritte

EstebanLM wrote >Other thing, to the maintainers of Magritte: Why is 3.2 not promoted? it is there since a couple of months nowâ¦ It should be fixed first. Grease stable is 1.1.8, and 3.2 refers to 1.1.6. Lots of configurations use references to #stable of Grease. That does not combine well with configurations using numbered versions.

Re: [Pharo-users] Problem learning about Magritte

by Esteban Lorenzano

Do not worry. We are here to (try) help you. And we will do it if it is in our capabilities... Yes, some times it is not enough, I understand, but then you have to be a bit patient, but we will get into the point to help :) As I told you some mails before, even the magritte-morph package was updated. What was not is the configuration. In fact, there is a configuration that works: version 3.2â¦ is just that it was not promoted as stable. Now, why it was not promotedâ¦ is a problem of maintainers of the package, not pharo itself, ven if magritte is an important part of us, we cannot take responsibility of every single package that is published. And it is not a problem of just us, you will see that in many other platforms. We have a lot of people contributing (and I thank the good will spirits for that, and we would really like to count you in as a part of them), but one of the problems of being open is that you cannot control everything. Is a price to pay. The advantages are that you became a lot bigger that you would be by yourself (or closed). Nowâ¦ communication is not out strongest part. Documentation either. We have to improve it, but it is not hard and it will take some timeâ¦ in the mean time all what I can offer you is this great community. We are not perfect, we have a lot of failing stuff and things to improve. But we are always trying to help. Please keep pushing and we will respond. Other thing, to the maintainers of Magritte: Why is 3.2 not promoted? it is there since a couple of months nowâ¦ cheers, Esteban On 14 May 2014, at 23:32, PBK Research <peter(a)pbkresearch.co.uk> wrote: > stepharo > > I was not setting out to insult anybody, and if you feel insulted by my > comments then I apologise.
