Hi Peter I wanted to ask about Bloc: Thanks for your interest :) 1) how stable is the API? e.g. if some overhaul changes to unify/whatever

are planned

Api itself is in "final" state, however naming might be improved (changed with or without depreciations). But don't worry user-side api is already in a very good shape, at least from our perspective :) 2) I saw in the techtalk that you can align elements (to center, bottom,

...), however is that possible with lines? Lines have to rotate, morph shape, etc.

3) Are non-straight lines possible? (e.g. bezier, arc) Exactly :) Lines are just bloc elements as anything else: buttons, text images. They can be linear, can be arcs or bezier curves (both quadratic or cubic). Default canvas used for rendering in Bloc (SpartaCanvas) has very good support of vector shapes and lines. The idea for me is to make a simple mindmap

- elements with some text, icons, math symbols inside - connectors (non-straight lines) between elements

It is very doable. Please, don't forget that Bloc is a low level framework that does not contain any widgets (existing ones will be deleted, especially BlLine, BlText and BlTextElement). The only responsibility Bloc has is to provide a basic infrastructure that does not put any constraints on users. Which means that if you want to have a bezier line you have to subclass BlElement, implement corresponding accessors for anchor points and override drawPathOnSpartaCanvas: in order to display you line. You can learn more about canvas by checking SpartaCanvas class comment and method comments in 'api' protocol. Layouts, alignment, transformations are part of bloc and are available to all subclasses of BlElement. Cheers, Alex On 22 February 2017 at 21:32, Peter Uhnak <i.uhnak@gmail.com> wrote:

To me (apart from the lines) it seems like it should be already doable.

Also either my (Morphic) Pharo is really slow, or Bloc (in the video) is superfast (everything is happening instantly).

Hi aliaksei


I would love to start to play with Bloc to build a game with boxes.
Now is there any tutorial that I can follow to get started?

Hi Sean, Yes, the idea of a simple game in Bloc progressed in a tutorial and a booklet. Here is the repo with all needed information and a link to the booklet: https://github.com/pharo-graphics/Tutorials/ I highly recommend to do a step-by-step tutorial :) It teaches how to create new elements, draw on canvas, compose elements and handle ui events.

Did you guys ever make any progress on this? I am very interested and would like to participate if it becomes a team effort…

No, mind map was not implemented :) Cheers, Alex On 26 November 2017 at 00:01, Sean P. DeNigris <sean@clipperadams.com> wrote:

Thanks. I went through the tutorial and enjoyed it. My message was specifically about a mind map implementation :)

Aliaksei do we have support for lines? Stef On Sun, Nov 26, 2017 at 9:48 AM, Peter Uhnák <i.uhnak@gmail.com> wrote:

Only recently I finally managed to get started with Bloc. But it is mostly experiments. Mindmap has currently no timeline. (But I will be eventually porting my OpenPonk to Bloc ... Mindmap could be a nice usecase).

Yes. They are supported since a long time.

Alex just added support for bezier curves. For example: https://twitter.com/feenkcom/status/934765444464021504

"Every successful trip needs a suitable vehicle."

I'm happy to hear that. I understand that Bloc is low-level, but I wanted to start getting familiar with it (Roassal3 should eventually be on top of it, so I need to understand the basics anyway).

It is very doable. Please, don't forget that Bloc is a low level framework that does not contain any widgets (existing ones will be deleted, especially BlLine, BlText and BlTextElement).

I am not sure how am I to interpret removal of BlText and BlTextElement. Does this mean that I would have to compose characters (is there BlCharacter) by myself? (I am not sure what the complexity implications are). But I am happy that all the things are in place, so I can slowly (weeks, months) start playing with it. Thanks!
