Re: [Pharo-users] Generate latex from Pharo

by Cyril Ferlicot

Hi, I don't know if there is a framework but if you don't find you can still take a look at the class PRLaTeXCanvas and PRLaTeXWriter from Pharo. Maybe that'll help you to make something.

Generate latex from Pharo

by Julien Delplanque

Hi everyone, Is there any framework to generate latex code from Pharo? I would like to give a latex representation to some objects so I can export the latex code to a file I would include to my latex main file (for example). For example for a matrix I would like to do something like: fileStream nextPutAll: myMatrix asLatex. to have something like: \begin{pmatrix} 1& 2\\ 3& 4 \end{pmatrix} in the file. I used to do it with pylatex in Python and I wonder if something equivalent already exists in Pharo? Regards, Julien

Like most things in Smalltalk, there is much more here than meets the eye! While pharo's main window looks like a desktop with windows, it is actually a world of living objects. Morphic is in fact a simulation framework based on the values of liveness and directness [1], which we are using to simulate a window system :) Two quick initial explorations: Create a morph: 1. DoIt: Morph new openInWorld 2. Click on the Morph while pressing (on Mac) shift+alt to bring up the Morph's "halo" (like a circular menu). From here, clicking the wrench (right side, second from the top) and then "inspect morph" will open an inspector on the object, and you can manipulate it like any other object. For example, `self color: Color white` immediately turns it white. As this doesn't seems to be your first rodeo, I'm sure you can quickly imagine the power of having all one's live UI objects immediately responsive on the same level as any other object without any context switch. Treat a window as a Morph: Repeat #2 above to get the same halos around the window. This is especially cool when hacking on the IDE because you can bring up the halos on a button, see what it's action is, and duplicate/modify it. One of the easiest cool demos, which is actually so easy that it's extremely hard to grok the implications of it, is to bring up the World menu, hover over a deeply nested item, bring up the halos on the item, pick it up [2], drop it in the world, and then click it. Of course it continues to work as if you had clicked it right in the menu. [1] http://web.media.mit.edu/~jmaloney/papers/DirectnessAndLivenessInMorphic.pdf [2] black button, middle-top, looks like a picker arm in one of those toy grabbing games they have at diners ----- Cheers, Sean -- View this message in context: http://forum.world.st/Alt-tab-between-windows-tp4826593p4826731.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Re: [Pharo-users] Alt-tab between windows

by Esteban Lorenzano

my answer on stackoverflow: well... you hit one of our weaker spots :) Keybindings are not in his best shape, but: - Actually, alt+tab is already set to "switch window" activity. The problem is that does not work all the time (for example, it does not work on Playground). - This is because there are some hardcoded logic there, who we are removing slowly from the system (some of those parts have more than 15yrs since they come from before Pharo has born). - Someone (probably in a failed attempt to fix the playground, or the hardcodes) forget a halt in the method who creates a new preview window... so even if you reach that part of the system, you will have a debugger. Of course, you will be able to restore correct behaviour by just removing the breakpoint, but that will not correct the fact "switch windows" will not be available everywhere. - I opened a bug entry for it: https://pharo.fogbugz.com/f/cases/15546, in case you want to follow the issue (you will need an account there, I'm sorry for that). In any case, we are moving out this hardcode stuff, and you can check all currently available settings going to **World Menu/System/Keymap Browser** (they are a lot, we are also playing with ideas on how to show better this combinations... emacs style, popup notifications, etc.) Esteban ps: I will like to have a solution for this, if anyone can help a bit in this areaâ¦ but it has to be a solution using the keybindings framework. I will deny integration to any hardcoded solution :) > On 16 May 2015, at 10:59, Dimitris Chloupis <kilon.alios(a)gmail.com> wrote: > > does not work for me in macos.

Yes, I agree this is not the best approach. I've just added support for SQLite's online backup API to NBSQLite3. (See my blog.) Garage's forking means it does not directly benefit from improvements to NBSQLite3. Now, this being Smalltalk, I reckon that some metaprogramming magic will allow me to add the new stuff in NBSQLite3 to Garage, but overtime as the code bases diverge this gets difficult. Pierce
