Re: [Pharo-users] Changes file size
Esteban, You might be on something important there. I always found it strange what effect loading Glorp had on an image, blowing it up. I can't say I understand though, best make it into an issue.

>I always found it strange what effect loading Glorp had on an image, blowing >it up. Looks like it is really an effect of the Glorp code. Maybe because it was initially exported from VW and then imported into Squeak/Pharo. I always thought slow loading is because of this or the long license texts in the classes. At least I had similar issues when I loaded the "Glorp-EstebanMaringolo.92" from October 2014. I was not able to browse diffs, etc. when I wanted to clean up. Then I commited "Glorp-TorstenBergmann.93" without real changes and things started to stabilize. At least I was able to browse the diffs afterwards and could refactor a little bit with Glorp-TorstenBergmann.94. Bye T.
[Pharo-users] Nautilus groups
Hello, We would like to know if some of you use Nautilus groups functionality: dynamic groups: 'Last modified packages', 'Most viewed classes', 'Work' user defined groups : from the menu, you can flatten the content of many packages and get all classes into the newly created group. We have the feeling that it is not used (or not a lot) and we think to replace it with another mechanism (for example, let the user define his/her 'favorites' classes / packages). Thanks for the feedback.

Re: [Pharo-users] Nautilus groups
I've never used the groups - mainly because I've never seen a sample workflow that I could copy, and my existing workflow is "sufficient" (which means I get a mess of windows plastered all over the screen as I follow sender&implementors, and could probably do better). btw, I've just spent 60 seconds trying to work out how to add an item to a group and could not. I don't even know what it groups - packages, classes, methods??? So I guess I ignored it, and once ignored, its a bit like that broken step in you building you always walk around without noticing. So discoverability of how to use it could be better, like something in the tooltip that "links" a more extensive tutorial on it, either in or out of image. cheers -ben On Tue, Feb 10, 2015 at 9:51 PM, Luc Fabresse wrote: > Hi Christophe, > > > > 2015-02-10 14:28 GMT+01:00 Christophe Demarey >: > >> Hello, >> >> We would like to know if some of you use Nautilus groups functionality: >> >>- dynamic groups: 'Last modified packages', 'Most viewed classes', >>'Work' >> >> I do not use dynamic groups. > > >> >>- user defined groups : from the menu, you can flatten the content of >>many packages and get all classes into the newly created group. >> >> I do not like to flatten > > >> We have the feeling that it is not used (or not a lot) and we think to >> replace it with another mechanism (for example, let the user define his/her >> 'favorites' classes / packages). >> > > +1 > > I would prefer to be able to save a regular expression (the one I enter in > the text area above Package list) > > > Cheers, > > #Luc > > > >> >> Thanks for the feedback. >> >> >

[Pharo-users] recover lost changes
To whom can answer me Working with Pharo 3.0 I noticed for a while that I could not recover class definitions (do it's) from the "Recent Changes". I also lost class comments on file-out / file-in . For the second problem I made the following test: 1. take a fresh Pharo 3.0 image (bundle for Mac OSX from Aug 29, 2014) 2. create MyClass with a class method and a comment. 3. file-out MyClass 4. remove MyClass on remove of MyClass I get an exception: https://www.dropbox.com/s/unq89t84tq7r60b/removeClass.tiff?dl=0 5. file-in MyClass The class is there - no error But: With the same exception in other images the comment is missing after file-in. Is this known?

Well, it is not yet clear but at least, do not flatten all classes and keep packages.
[Pharo-users] Externally signalling pharo VM for shutdown
Is there a way I can externally signal a running pharo-vm in order to request a shutdown equivalent to clicking on the close icon? I'd like to externally manage the start/stop of a Pharo image, but because the image can be used during development, I'd like to provide the user with a confirmation dialog instead of simply killing the process.

You can dive-in using cmd+shift+right-arrow in Spotter and follow observation of those implementors. Preview is available by cmd+p. So basically you open in a browser only one specific method.

Sven made a ZnReadEvalPrintDelegate that you can easily hook in to execute a smalltalk snippet (if your host is secured).

Re: [Pharo-users] Spotter: Browse Impementors?
Hi, As Juraj said, you can Cmd+Shift+ArrowRight to dive in the category and using the preview you can browse the code. If you want the MessageBrowser, there is no way to get it by default. Laura also asked for this feature before, so I listed below a crude code to add a processor that finds selectors instead of implementors. Just install this method and then start spotting. Let us know if this is better: GTSpotter>>spotterSelectorsFor: aStep | processor | processor := aStep listProcessor. processor title: 'Selectors'; filter: [ :originalQuery :stream | |query selectors | query := originalQuery trimBoth asLowercase. query isEmpty ifFalse: [ selectors := Set new. SystemNavigation default allBehaviorsDo: [:class | class selectorsDo:[ :selector | ((selectors includes: selector) not and: [ selector beginsWith: query ]) ifTrue: [ selectors add: selector. selectors size > 5 ifFalse: [ stream addObject: selector inProcessor: processor . selectors ] ]; actLogic: [ :each | self systemNavigation browseAllImplementorsOf: each ] Cheers, Doru On Tue, Feb 10, 2015 at 9:24 PM, Sean P.

[Pharo-users] Problems evaluating message sends in run-time arrays
I would like to create an array with a collection of colour values.
I tried both:
colorList := {Color blue}
and
colourList := {Color named: #blue.}.
In both cases it evaluates to 'Color blue' rather than the Color object.
What surprised me was that:
charList := {Character digitValue:35. Character digitValue:33.}.
Does evaluate to an array of two characters. What is going on?
Cheers
Andy

It's print string is 'Color blue'.

Re: [Pharo-users] Problems evaluating message sends in run-time arrays
I'm away from my Pharo computer to double-check, but is it just that is how
a Color object displays itself ? Maybe have a look at Color>>printOn:

So now i can open a volatile or persistent Spotter, i'm going to have a keycombination for each one. In addition i get all the regular window behavior i in some cases want. This makes me really happy :) Only one little keybordian issue, Cmd+w doesn't close the window as usual, the same happens with GTPlayground.

So now i will define a category for classes+selectors and map a keycombination to open a volatile Spotter on ti, and remove the 5 results limit (how do i do this?). This gives me my wanted "selector/class shortcut" Spotlight provided me, improving the annoying deficiency Spotlight has of showing no-longer defined names (i asked about it in a recent mail to the list). Having a shortcut (Cmd+Shift+ArrowUp/ArrowDown) to jump through categories, then why to limit the number of results in each category to 5? Why not to show them all to avoid the need of going into the category? > Did you try compiling the method that I sent in the previous mail > (basically just copy paste that method in the GTSpotter class)?

I face this issue, if i type 'openIn' i get only 1/1 selector #openeningDelimiters, and only if i continue to type 'openInW' i get 5/28 selectors. Also at some point i started to get an #inform: msg saying "WorldState interCyclePause failed". So additions i would like to see built by default Cmd+w to close on GTSpotter and GTPlayground. Remove/know-how-to remove the 5 limit on results. Selectors category. Font size configured at SystemBrowser to have effect on GTSpotter both on search results and preview. To summarize i love Spotter and it will be the tool i use the most (in number of openings). Love, Laura

That was my fault since build 40477 integrated Issue 14669. This should be fixed since Issue 40874 was integrated into build 40486 . cheers -ben
Re: [Pharo-users] SmaCC: First steps
Ok so after rereading the tutorial and testing again and again , I think I
have finally managed to understand how SmaCC really works and I was
succesful into converting simple python litsts to pharo arrays and ordered
collections.
The tricky part now is to apply this knowledge to complex python types like
multi dimensional lists, tuples and dictionaries. I understand that the
visitor allows me to visit a specific object instances each time they are
found in the AST . But because I want to walk the AST in order to build
multi dimensional ordered collections I need something more, or maybe my
understanding of the visitor pattern is flawed.
The problem I am having here is that each time I parse a python type that
python type is not necessarily represented by different kind of node. For
example whether its a list or a tuple or a dictionary the same class is
used PyAtomNode. In order to differentiate between those diffirent python
types PyAtomNode has instance variables for right and left bracket,
parantheses, and curly. So my initial thinking is to check those instance
variables to see if they are nil and from that I can conclude which python
type I am parsing.
So I can preform simple ifs that check that the instance variable is Nil or
not but the question is if my strategy is a good one or a bad one.
I could define my own syntax to simplify the AST tree including different
nodes for different python types , because from the looks of it , it seems
it is a bit too verbose for my needs but On the other hand I am not so sure
because in the future my needs may become more verbose too.
So I am very close and ready to create my full python types converter for
pharo but I wanted some good advice before wasting time on something that
is not efficient.
By the way Thierry I have to agree with you Smacc is a very capable parser,
also I like the use of regex syntax, makes it uglier compared Pettit Parser
but I prefer the compact regex syntax to having to define and browse tons
of classes and send tons of messages. Also the Python support is very good
and I am impressed how easily SmaCC can parse whole python applications
since some of the test are very complex. Well done great work!
