Glamour: update presenter with new text

by Hilaire

Hi, In the method bellow, when the method is recompiled, the presenter's text is still the same (i.e. select another method, then the modified method: the former source code is still presented). How to request an update of the presenter's text with the newer method source? sourceIn: composite ^ composite text title: 'Source code' translated; display: [ :aCompiledMethod | aCompiledMethod sourceCode ]; act: [ :presentation :compiledMethod | compiledMethod methodClass compile: presentation text] on: $s entitled: 'Save' translated Thanks Hilaire -- Dr. Geo http://drgeo.eu

Re: [Pharo-users] Custom Glamour browser for Dr. Geo scripting

by Hilaire

Thanks Andrei for the tips! After adaptation, I have this script browser. I will look to improve it a bit more with menu and syntax colouring. The wrapper part of your solution reads like Chinese to me. May be I am miss using Glamour, and I will be happy to read about suggestions for better use.

Re: [Pharo-users] PrimitiveFailed: primitive #createDirectory: in UnixStore failed

by Offray Vladimir Luna CÃ¡rdenas

Hi Jacob, This means that you uncompressed the file using root permissions instead of using default user ones, because you shouldn't need sudo to run Pharo. The alternative should be to change the permissions on the folder you made have Pharo so you don't need sudo each time. Something like sudo chown -R myuser:myuser PharoFolder/ should work. Cheers, and welcome to the community.

Re: [Pharo-users] Pharo command line, stdout and integrating with other tools?

by Tim Mackinnon

Thanks Andreas, I was just coming to the conclusion you have pointed out. I haven't had a computer to try it - but I'll try your example. If it works, I think this should almost be in the std image so that Pharo plays better with others straight out of the box. The " issue is when calling from other other languages (e.g. Nodejs). Try passing some Json as a parameter using exec and you hit this issue with the eval handler - but maybe with my own handler I can do something better? I need to study this and will report back.

Re: [Pharo-users] Pharo command line, stdout and integrating with other tools?

by Andreas Sunardi

If I'm not mistaken, this is Pharo's eval command line handler you're talking about. If so, it is not correct to say 'it also return the result of that method or yourself'. To return the result (and print it to stdout) of that method is the goal of eval command line handler. How about making your method to return empty string, or better create your own command line handler. I believe the minimal you need to do is to subclass EvaluateCommandLineHandler, override class method #commandName and override method #evaluate:. Something like this, perhaps ProceesCommandLineHandler class >> commandName ^ 'process' ProcessCommandLineHandler >> evaluate: aStream Smalltalk evaluate: aStream. Save your image, then you can call ./pharo -headless myimage.image process StandardFileStream stdout print: 42 and it'll print 42 and nothing else. I'm not sure I understand the double quote (") character issue that \" solves. Example?

Re: [Pharo-users] Custom Glamour browser for Dr. Geo scripting

by Andrei Chis

Hi, If I understood the issue correctly then the script below should address it. It starts from the solution Juraj proposed but wraps each presentation in a wrapper. The script is not that obvious as this is not really a use case glamour supports out of the box. Also in glamour multiple presentations displayed within a composite share the selection. To avoid that they need to be wrapped. The simplest solution is to use a GLMWrapper. -=-=-=--=-=-=--=-=-=--=-=-=--=-=-=--=-=-=--=-=-=--=-=-=--=-=-=--=-=-=- -=-=-=--=-=-=- browser := GLMTabulator new column: #one; column: #two; column: #three; yourself. browser transmit to: #one; andShow: [ :composite | composite fastList ]. browser transmit from: #one; to: #two; andShow: [ :composite | composite wrapper title: [ 'Instance' translated ]; show: [ :wrapper | wrapper fastList display: [ :aClass | aClass methods ]; format: [ :aCompiledMethod | aCompiledMethod selector asString ] ]. composite wrapper title: [ 'Class side' translated ]; show: [ :wrapper | wrapper fastList display: [ :aClass | aClass class methods ]; format: [ :aCompiledMethod | aCompiledMethod selector asString ] ]. composite onChangeOfPort: #activePresentation act: [ :presentation | (presentation pane port: #activePresentation) value ifNotNil: [ :activePresentation | ((browser paneNamed: #two) port: #selection) value: (activePresentation defaultPane port: #selection) value ] ] ]. browser transmit from: #two; to: #three; andShow: [ :composite | composite text display: [ :aCompiledMethod | aCompiledMethod sourceCode ] ]. browser openOn: Collection allSubclasses. -=-=-=--=-=-=--=-=-=--=-=-=--=-=-=--=-=-=--=-=-=--=-=-=--=-=-=--=-=-=- -=-=-=--=-=-=- Cheers, Andrei On Sat, Jul 1, 2017 at 4:46 PM, Juraj Kubelka <juraj.kubelka(a)icloud.com> wrote: > Hi, > > I am able to produce this: > > -=-=-=- > browser := GLMTabulator new > column: #one; > column: #two; > column: #three; > yourself. > browser transmit to: #one; andShow: [ :composite | > composite fastList ]. > > browser transmit from: #one; to: #two; andShow: [ :composite | > composite fastList > title: [ 'Instance' translated ]; > display: [ :aClass | aClass methods ]; > format: [ :aCompiledMethod | aCompiledMethod selector asString ]. > composite fastList > title: [ 'Class side' translated ]; > display: [ :aClass | aClass class methods ]; > format: [ :aCompiledMethod | aCompiledMethod selector asString ]. > *composite onChangeOfPort: #activePresentation act: [ :presentation | * > * (presentation pane port: #activePresentation) value* > * ifNotNil: [ :activePresentation | * > * self inform: activePresentation printString.* > * self inform: activePresentation selection ] ]* ]. > > browser transmit > from: #two; to: #three; > andShow: [ :composite | composite text > display: [ :aCompiledMethod | aCompiledMethod sourceCode ] ]. > > > browser openOn: Collection allSubclasses. > -=-=-=- > > But I do not know how to change the column #three, because the selection > is shared between the two lists. > > I hope it helps and someone else can improve it :-) > > Cheers, > Juraj > > > > > El 01-07-2017, a las 10:48, Nicolai Hess <nicolaihess(a)gmail.com> escribiÃ³: > > > > 2017-06-30 9:55 GMT+02:00 Hilaire <hilaire(a)drgeo.eu>: > >> I extended the browser definition with: >> >> browser transmit >> from: #scripts; >> from: #categories; >> to: #methods; >> when: [ :a :b | a isMeta not ]; >> andShow: [:a | self methodsIn: a ]. >> browser transmit >> from: #scripts; >> from: #categories; >> to: #methods; >> when: [ :a | a isMeta ]; >> andShow: [:a | self classMethodsIn: a ]. >> >> >> However it does not work as #when: message always receive a class, so >> the wrong methods a re list in the method pane. >> >> I enclosed a Fileout of the browser.
