PetitMarkdown
by Norbert Hartl May 3, 2015

May 3, 2015

I found markdown parsers in smalltalkhub and in the configuration browser. http://smalltalkhub.com/#!/~PharoExtras/PetitMarkdown/ <http://smalltalkhub.com/#!/~PharoExtras/PetitMarkdown/> and the one in the configuration browser PPMarkdown If I understand it correctly both are rooted into work Camillo did. The one in PharoExtras looks newer to me. So I assume the best would be to copy the ConfigurationOfPetitMarkdown from PharoExtras to MetacelloRepo and remove the ConfigurationOfPPMarkdown. Right? Or are there any objections? Norbert

Playground and its current usability in Pharo4.0 Latest update: #40307
by Torsten Bergmann April 24, 2015

April 24, 2015

While I like that GTTools are in Pharo 4 now (thanks!!!) and allow all kind of neat things I basically ask myself if we forgot to remember usability on a few places: 1. the world menu item "Workspace" opens a window "Playground" including also a tab with the same name "Playground". => CONFUSING I would suggest that we rename the window "Workspace" and keep "Playground" for the initial tab. This is easy to fix and would also fulfill the expectation when a beginner grabbed an existing Smalltalk or Pharo book. 2. While in all UI interfaces (Windows, Linux, Mac) the order in the context menu is "Cut", "Copy", "Paste" the playground menu uses a different order "Copy", "Cut" "Paste". => CONFUSING again I would suggest to use the well known order "Cut","Copy","Paste". 3. When one uses "Inspect it" from the context menu it means - to run the code - and the resulting object is then "inspectable" in a new window On the other side "Do it and go" from the context menu means - to run the code - and the resulting object is then "inspectable" in a new pane (but same window) The intention of both menu items and also the result is the same, but the naming is different ("go" vs. "inspect"). But the only notable difference is that in one case the inspectable object is opening right to the existing pane in the other case a new window is opened. => CONFUSING and inconsistent This is harder to solve. Possible solutions are: 3a. We keep the "inspect" concept and name the menu items "Do and Inspect it" and "Inspect in new window" 3b. We keep "Do it" as before to run the code, also "Inspect it" which opens the new pane to the left in the same window. If someone wants to open a new inspector window he should keep SHIFT key pressed while running "Inspect it". This is a concept known from web browsers and other tools today, clicking on a link while pressing SHIFT opens a new window. 4. The icons in the context menu of Playground are not the same as the ones in the Pharo browsers. => CONFUSING and inconsistent They are just black and if one switches to the Pharo dark theme they stay black and therefore looking ugly and make nearly no sense on the dark grey menu background. For now we should use the known icons that we already have. Maybe currently they are hardcoded and may conflict with Moose vs. Pharo icons - but this could be solved with the Icon Theming. (In the long term I would like to see scalable icons in Pharo menues (instead of bitmaps) similar to "Fontawesome" in web browsers (two colors) or SVG based ones (more colors) as currently the icon does not scale when changing the menue font size). Sorry if it sound like a rant - but the intention of this mail is that we discuss (and hopefully fix) in order to improve. Maybe it is written too early after the initial integration, but I think the mentioned points should be easy to address. Unfortunately I'm additionally confused with the changed contribution process that has exceptions for specific packages like GT to fix it myself with the usualy bugs/slice cycle. Thanks T.

Ugly textrendering (vertical label)
by Nicolai Hess April 17, 2015

April 17, 2015

Someone knows, why the text on the completion morph is so ugly? For example, this text Morph ne will open a completion window for "Morph class". This name is a vertical label on the left. The text looks ugly when we are using a FT font. Can we do anything to make this look better ? I know that (smooth) text rendering is difficult for arbitrary rotated forms, but this rotation around n*90 degree works with StrikeFont. nicolai

Duration year
by Hilaire March 26, 2015

March 26, 2015

I saw some discussion about Duration and year calculus in the list Given that it is impossible to determine the number of days in a year without the calendar years, should not 365.25 be used in place of 365 to minimize the error ? So it could look like: Duration class >> years: aNumber ^ self days: (aNumber * 365.25) truncated seconds: 0 Hilaire -- Dr. Geo - http://drgeo.eu iStoa - http://istoa.drgeo.eu

GLMBrick whats next?
by Nicolai Hess March 25, 2015

March 25, 2015

I took a look at GLMBrick and I am wondering what is the intent: - a temporary solution until this functions/behavior are included in Morphic - a layer on top of morphic without the intent to do this in Morphic any time. - a temporary solution until this functions/behaviors are implemented with bloc nicolai

[ANN] RProjectConnector V1.0
by Blondeau Vincent March 17, 2015

March 17, 2015

Hello everyone, I am glad to announce the first version of the RProjectConnector, a binding between Pharo and R using NativeBoost. You can now call directly your R methods from Pharo: data := (1 to: 1000) collect: #yourself. res := (#acf asRFunctionWith: {data}) eval To use it, you should copy the R libraries near the Pharo VM (see the documentation on SmalltalkHub to see how to proceed) and Gofer it smalltalkhubUser: 'VincentBlondeau' project: 'RProjectConnector'; configuration; loadStable Don't forget to relaunch Pharo after the installation to be able to use the connector. The sources are available on Smalltalkhub: http://smalltalkhub.com/#!/~VincentBlondeau/RProjectConnector if you want to participate, just ask me!
