[ann] bloc & cairo+morphic

by Tudor Girba

Hi, We are happy to announce that based on the work of Glenn, Alex extended Bloc (Sparta) to work directly in the Morphic world using Cairo as a backend. Cairo is less powerful than Moz2D (see the screenshot below for an example), but the implementation addresses a concern that the community raised regarding a perceived increased liability due to the dependency to Moz2D. Essentially this means that Bloc can be treated as another graphical library that can coexist with Morphic without requiring any external VM plugin. I would also like to point out that adding a new backend and host was possible because of the many iterations (including throwing away whole implementations) that Alex and Glenn went through. I think they did an amazing job. You can find a bit more details about Bloc here: http://www.humane-assessment.com/blog/bloc-flexible-backends-hosts/ Another issue raised regarding Bloc was that of the engineering effort required to make it a reality. That is why I would also like to announce that Alex joined feenk.com where he is primarily working on the graphical stack for Pharo. Cheers, Doru -- www.tudorgirba.com www.feenk.com "To lead is not to demand things, it is to make them happen."

Hi All, Here is a basic example for doing a very simple syntax highlighted text editor: ===== styler := MyTextStyler new. browser := GLMTabulator new. browser row: #row. browser transmit to: #row; andShow: [ :composite | composite custom: (GLMRubricHighlightedTextPresentation new editingMode: [GLMHighlighterTextRubEditingMode withStylerDecorator: (GLMHighlighterTextStylerDecorator new styler: styler)]) ]. browser openOn: 'Some text with highlighting $@'. ===== Best regards, Ronie 2017-05-08 11:42 GMT-03:00 Offray Vladimir Luna CÃ¡rdenas < offray.luna(a)mutabit.com>: > Hi, > > I would like something along the lines of the recent code syntax thread. > Maybe something like: > > =============== > > TextModel new > isForCode: 'markdown'; > text: (Collection>>#anyOne) sourceCode; > aboutToStyle: true; > openWithSpec > > =============== > > This would do a great adding for Grafoscopio. > > Cheers, > > Offray > > > On 07/05/17 11:57, phil(a)highoctane.be wrote: > >> I want to do such an editor. >> >> Preferrably something fast. >> And in the current Pharo. >> >> There have been several text models, Rubric etc. >> >> What is the quickest way to get such a thing? >> >> Features: >> >> Load/Save content >> Highlight keywords based on syntax parsing >> Act on the element under the cursor >> Act on the element when (modifier)clicking on it (or hovering). >> Fast (or at least, not sluggish on a "normal" (ie Core i5 1.8Ghz) laptop) >> >> This is really something I miss being able to do in Pharo. >> >> Lots of code is using "STHStyler" things but there seems to be no easy >> way to extend that (as it seems to be using the AST or something like >> that). >> >> I am okay with a first easy approach to highlighting, like in Vim >> where one puts a syntax file with not that many things. >> >> Phil >> >> >> > >

Hi, I would like something along the lines of the recent code syntax thread. Maybe something like: =============== TextModel new isForCode: 'markdown'; text: (Collection>>#anyOne) sourceCode; aboutToStyle: true; openWithSpec =============== This would do a great adding for Grafoscopio.

Dolphin Smalltalk has such an editor - so it might provide inspiration for you. It uses the scintilla library which I notice does support windows/osx/linux ( http://www.scintilla.org/ScintillaDownload.html <http://www.scintilla.org/ScintillaDownload.html> ) but it might be more than what you need given Pharo has over the years added many things that get it close (just not the colour coding) Tim > On 7 May 2017, at 17:57, phil(a)highoctane.be wrote: > > I want to do such an editor. > > Preferrably something fast. > And in the current Pharo. > > There have been several text models, Rubric etc. > > What is the quickest way to get such a thing? > > Features: > > Load/Save content > Highlight keywords based on syntax parsing > Act on the element under the cursor > Act on the element when (modifier)clicking on it (or hovering). > Fast (or at least, not sluggish on a "normal" (ie Core i5 1.8Ghz) laptop) > > This is really something I miss being able to do in Pharo. > > Lots of code is using "STHStyler" things but there seems to be no easy > way to extend that (as it seems to be using the AST or something like > that). > > I am okay with a first easy approach to highlighting, like in Vim > where one puts a syntax file with not that many things. > > Phil >

Phil, It is something that I want too in Pharo. Especially for rendering Markdown / Pillar. I'm willing to help if you need a hand. Don't expect a pro developer but I will do my best. Let me know.
