[Pharo-dev] [Reflectivity] What are the #arguments?

[roberto.mine...@usi.ch]

Dear Marcus,

I am wondering where to ‘discover’ all the possible values for the #arguments: 
to pass to the MetaLink.

Cheers,
R

Re: [Pharo-dev] [Reflectivity] What are the #arguments?

[roberto.mine...@usi.ch]

Thank you very much, Marcus!

Concerning the table..we can do a method that lists the #availableReifications 
or something like that ;)

For example, if I am interested in all the available reifications for an 
RBMethodNode I can do:
RFReification subclasses select: [ :e | e nodes includesAny: RBMethodNode 
withAllSuperclasses ].

Cheers,
Roby

Hi Marcus,

I am finally playing with Reflectivity. In the first place, thanks a lot for 
this contribution!

I am wondering what is the ‘correct’ way to ‘remove’ a MetaLink. Is it enough 
to call #uninstall on the MetaLink or should I also recompile the class/method 
where the link is installed?

I spotted a problem with the control #after. If you try to pass #arguments to 
the meta, an error is returned. To reproduce: http://ws.stfx.eu/ONC4K9KQRTNQ

Is this behavior somewhat desired, or is a bug?

[Pharo-dev] Pharo 5 and method extensions

Dear all,

I just moved to Pharo 5 for development and discovered that it does not

[Pharo-dev] Configuration Madness

[roberto.mine...@usi.ch]

Dear all,

I have a question about the ConfigurationOf my project, and I really hope you 
can help.

In my project I have a package called ‘DevFlow-Extensions’ that is a 
“placeholder” for code that is dependent on the Pharo version.

On the ConfigurationOf, according to the Pharo version I do something like

spec for: #'pharo3.x'
do: [ 

spec blessing: #baseline.
spec repository: 
'http://smalltalkhub.com/mc/RobertoMinelli/DevFlow/main'.

spec package: 'DevFlow-Extensions' with: 
'DevFlow-Extensions30'.
].

spec for: #'pharo4.x'
do: [ 

spec blessing: #baseline.
spec repository: 
'http://smalltalkhub.com/mc/RobertoMinelli/DevFlow/main'.

spec package: 'DevFlow-Extensions' with: 
'DevFlow-Extensions40'.
].

In this way, in Pharo 3.0 I’d load DevFlow-Extensions30 and in Pharo 4.0 I’d 
load DevFlow-Extensions40. Super cool.
I am using a single package (‘DevFlow-Extensions’) to specify of groups, for 
example:

spec group: 'User' with: #(
'DevFlow-Meta' 
...
'DevFlow-Announcement'
'DevFlow-Extensions'). 

Now the problem is that for Pharo 5 I have to load both 'DevFlow-Extensions40’ 
and 'DevFlow-Extensions50’. 
I read the chapter on Metacello, but didn’t find a solution. I tried some 
combinations of #includes: and #requires: but with no luck.

Any help is appreciated, thank you very much!

   How silent should compileSilently be?
 
   no trace in the system :
   15314 https://pharo.fogbugz.com/default.asp?15314
   compileSilently and method history / changes file
 
   not half silenlty
   13023 https://pharo.fogbugz.com/default.asp?13023

   not SystemAnnouncer-silent
   10560 https://pharo.fogbugz.com/default.asp?10560
   SystemAnnouncer and compileSilently
 
 
   ?
 
   What do you think, what granularity of silent do we need.
   I see at least three different use cases:
 
   - just an ordinary compile
 
 
   ? Silent means that: Core infrastructure is not updated properly
   (i.e. RPackage) and tools (Browsers) can end desynchronised with the
   methods.
 
   - compile for tests
 
 
   Probably the one... But I wonder if this is a good idea anyway. I'd
   believe most tests using silently are using it wrongly and shouldn't
   be using it in the first place.
 
   - compile autogenerated methods.
 
 
   This one may not be silent. If the auto-generated method will be
   visible (saved in a package, can be browsed, etc...) then it
   shouldn't be silent.
 
 
 
 What about compiled method for which the source did not change?
 
 Hum. I see what you mean.
 
 I do silent compilation when I install tracing probes inside methods, to 
 make sure they don't appear as changed in browsers... But I don't create 
 new methods. I guess this will be the same with the MetaLinks Marcus is 
 preparing.
 
 But, yes, as I said: methods or changes that are not visible then you can 
 make them silent.
 
 But in a different case, such as compiling a SmaCC parser, you want that 
 code to be visible.
 
 
 For NativeBoost generated methods, I may want to have that code visible too.
 I just don't want the code to be marked as changed after a recompilation.
 
 For example, a subclass of NativeBoosts NBExternalStructure or 
 NBExternalArray must be recompiled when used in a new session, or when the 
 structure
 changed.
 
 The compiler installs the generated accessor methods and you may want to 
 see that code - just to make sure the structure change was applied.
 But you really don't want this code in a changeset, because whenever you 
 use this code in another image or in a new session it
 will be recompiled  anyway.
 
 
 
 I am interested on this for issue 15315, everytime you open spotter,
 you'll get a new
 
 method: PharoSyntaxTutorial divideTwoByZero; AutoGenTutorial 5/28/2015
 20:34
 
 in you changes file.
 
 This one makes for some annoying noise in the changes. But as I say below, 
 maybe it doesn't matter.
 
 Another case are autogenerated methods from NativeBoost.
 For example, open a fresh image and execute code that triggers
 NativeBoost to install native functions for this session.
 (EllipseMorph new openInSceneView)
 
 And now look at your list of recent changes.
 I get about 30 entries for athens/cairo methods.
 
 One of the thing to consider is what you use the changes for. If it is to 
 recover from crashes, then what you just need to make sure is that 
 replaying all since the last save is ok... even if you have multiple times 
 the same method source saved in it.
 
 Yes, you are right. It does not hurt to have this in the changes file. (But 
 it does not have any use to be there).
 
 
 True changes management is happening in the packages these days, and most 
 code written in the changes shouldn't be recorded there imho (oh, well, 
 apart for the source pointer, of course).
 
 And other uses it could have (recording all do its, for example) is 
 reimplemented / duplicated elsewhere in the system anyway.

[Pharo-dev] [Reflectivity] HowTo

[roberto.mine...@usi.ch]

Dear Marcus,

I am following your progresses on Reflectivity and I’d like to start with a 
big: THANK YOU!

Having said that, I am wondering whether this is a good point in which I can 
try (as an alpha tester :) to use it.

What I need to achieve is something similar to a method wrapper, i.e., some 
code that gets executed before or after a particular method call.

Is something doable at this point? Could you _please_ provide me pointers where 
to look to understand the Reflectivity framework?

Cheers and thanks in advance,
Roberto

Re: [Pharo-dev] Collecting user data

[roberto.mine...@usi.ch]

+1 I couldn’t agree more with Andrei. 

I believe that we should have a common infrastructure, at least, to define 
which level of details tools are
allowed to collect/send for research purposes. I envision a setting’s panel in 
which the user has a list of
tools collecting data with their own settings and the user can freely select 
which tools are allowed to 
collect her data.

I had another idea, a “research image”. Let me explain, people are struggling 
to install tools that are not 
part of the standard image. On the other hand, having your research tool part 
of the standard image, is not 
easy for a number of reasons. So what about having a  “research image” that 
allows researcher to install and
distribute their own tools? Brave developers, for their free time project, 
could use this image instead of the
standard distribution, benefit from the innovative (but in early stage) tools 
and contribute to the data
collection mechanisms?

Roberto

 How data is collected/stored will differ from tool to tool, but agreeing

them, do you mark them as false positives? If we had answers to
these questions, we could really make good and helpful critics.
 
 For now I know that there are 3 projects which collect data:
 - GTSpotter
 - Shoreline
 - DFlow (not in image by default).
 
 Should I make 4th data collection for QualityAssistant? Or maybe
we can do some unification?
 
 
I would love unification!
 
It’s not only good for the researchers, but even for the user: I do
not want to decide 5 times to give data to research,
but I want to decide it once…

[Pharo-dev] ZnClient send big data + progress

[roberto.mine...@usi.ch]

Hi guys,

I have a problem with Zinc, I need to send a huge amount of data (bytes) that 
translates to ~50Mb.

When I do something like:

ZnEasy 
post: 'http://localhost:15432' 
data: (ZnEntity bytes: aHugeByteArray.]

I encounter a ‘ConnectionTimedOut: Data send timed out.’, I attach the stack 
trace:

ZdcSocketStream(ZdcSimpleSocketStream)flushBytes:startingAt:count:
ZdcSocketStreamnext:putAll:startingAt:

I tried to:
- Augment the client timeout to a huge value (10 mins) but it has no effect: 
The data send still goes into timeout, after 10-15 sec
- I replaced the ZnEntity with a ZnMultiPartFormDataEntity, still no luck

I am wondering what else can I do.

Moreover, I discovered there is a #signalProgress: message to signal process. 
The following examples do not work, any hint?


Example 1, from the book @ http://zn.stfx.eu/zn/zinc-http-components-paper.html:

UIManager default informUserDuring: [ :bar |
  [ ^ ZnClient new
signalProgress: true;
get: 'http://zn.stfx.eu/echo?delay=2' ]
on: HTTPProgress 
do: [ :progress | bar value: progress printString. progress resume ] ]


Example 2, from ZnClientTests#testProgress works, but not when issuing a POST 
request
[ :bar |
bar title: 'Downloading Sources...'.
[
ZnClient new 
url: 
'http://files.pharo.org/sources/PharoV30.sources'; 
signalProgress: true;   
downloadTo: FileLocator temp ]
on: HTTPProgress 
do: [ :progress |
progress isEmpty ifFalse: [ bar current: 
progress percentage ]. 
progress resume ] ] asJob run.
…works but only when using #downloadTo: if you do a #post:contents: or a #get: 
as in the example with #get: 'http://zn.stfx.eu/echo?delay=10' no process is 
shown. Any hint?

Thanks in advance,
Roberto

 Hi Roberto,
 
 Let's see. First we start an HTTP server in Pharo 3:
 
 (ZnServer defaultOn: 1701)
  onRequestRespond: [ :request | 
request inspect. 
ZnResponse ok: (ZnEntity text: 'OK') ];
  maximumEntitySize: 100*1024*1024;
  logToTranscript ;
  start.
 
 The handler code will always reply 'OK', but also inspect the incoming 
 request. I raise the maximum entity size to 100Mb.
 
 Here is a simple request:
 
 ZnClient new
  url: 'http://localhost:1701';
  entity: (ZnEntity with: (0 to: 255) asByteArray);
  post.
 
 Next is a bigger one (10Mb):
 
 ZnClient new
  url: 'http://localhost:1701';
  entity: (ZnEntity with: (ByteArray new: 10*1024*1023 withAll: 123));
  post.
 
 Finally the big one (50Mb):
   
 ZnClient new
  url: 'http://localhost:1701';
  timeout: 900;
  entity: (ZnEntity with: (ByteArray new: 50*1024*1023 withAll: 123));
  post.
 
 That fails indeed, and I don't know why (yet). The weird thing is, it fails 
 with only 6Mb written, always at the same position, while the 10Mb upload did 
 work OK. Raising the timeout does indeed not make a difference. Data is 
 written using 16Kb chunks, with progress notifications (see ZnUtils 
 class#nextPutAll:on:). 
 
 Luckily, there is a workaround, using the classic SocketStream somehow fixes 
 the issue:
 
  ZnNetworkingUtils default socketStreamClass: SocketStream.
 
 Now, for the progress indication, Zinc certainly does it correctly, but 
 somehow the UI does not always follow. You can verify this by writing to the 
 Transcript:
 
 [ :bar |
  bar title: 'Uploading...'.
  [
ZnClient new 
  signalProgress: true;
  url: 'http://localhost:1701';
  entity: (ZnEntity with: (ByteArray new: 10*1024*1023 withAll: 123));
  post ]
on: HTTPProgress 
do: [ :progress |
  progress isEmpty ifFalse: [ bar current: progress percentage ]. 
  Transcript crShow: progress.
  progress resume ] ] asJob run.
 
 Experiment with adding/commenting out the #crShow: you will see that it 
 works, sometimes.
 
 HTH,
 
 Sven

[Pharo-dev] [Fuel] Serialize and materialize to GZip

[roberto.mine...@usi.ch]

Hi,

Following the Fuel test FLUserGuidesTest#testGZip I discovered that I can 
serialize and materialize to and from GZip archives. Cool!

I tried with some small test object and it worked like a charm. When I tried 
with a large object…

Serialization
- It does not work, the image instantly crashes

Materialization
- Since I was not able to serialize the large object on GZip, I serialized 
normally than compressed the resulting fuel file using GZipWriteStream 
class#compressFile:
- When I materialize from the GZip archive, it takes forever and does not 
succeed after more than 1 minute. Note that the same non-Gzipped file takes a 
couple of seconds to be materialized.

How can I handle this?

Thanks in advance,
Roby

[Pharo-dev] Milliseconds in DateAndTime or TimeStamp

[roberto.mine...@usi.ch]

Hi,

I am wondering if there is the possibility to get milliseconds in a TimeStamp.

I need to record fine-grained events and second-granularity is not enough.

Cheers,
Roberto

Re: [Pharo-dev] Milliseconds in DateAndTime or TimeStamp

[roberto.mine...@usi.ch]

TimeStamp now rounds the timestamp, so #asNanoSeconds returns the seconds * 
10e9.

Doing “DateAndTime now” solves my issue, but this is a total non-sense.

Re: [Pharo-dev] Milliseconds in DateAndTime or TimeStamp

If done right, TimeStamp would have not caused any confusion. 
Now that I discovered that a TimeStamp is a DateAndTime with rounded seconds 
(read: non-sense) I agree with you.

Re: [Pharo-dev] [Fuel] Unexpected stream version 19

[roberto.mine...@usi.ch]

Hi Max,

Thanks for the answer in the first place. Besides the “unexpected stream”, I am 
also experiencing some weird behavior about memory consumption.

I have a folder with 70 fuel files, ranging from few kb to 40MB. Each file 
represents a development session with some of my objects inside. 
I have a method that scans that directory, with sub-directories, and 
materializes all the objects in the image.

Until last month, this worked like a charm but now, every time I launch it I 
got an OutOfMemory problem with the VM.

Do you have any idea how this is possible? I tried to increase heap size, pass 
the —memory option to the VM, force garbage collection but the problem 
persists. I also tried to load the old Fuel (1.9.1), the version I was using to 
export. Still no luck.

Thanks in advance for any help,
Roberto

[Pharo-dev] Detect when Pharo loses focus

[roberto.mine...@usi.ch]

Hi guys,

I am trying to detect when a user switches her focus from Pharo to another app.

In short I’d like to know when the user switches (i.e., atl+tab) from the Pharo 
application to another application, losing focus from the development.

I looked into Morphic and I was able to tell when the mouse goes outside the 
Pharo window.
Unfortunately this technique does not work when the user uses alt+tab to switch 
to another app, since the last mouse event is not outside the Pharo window.

Any suggestion where to look?

Thanks in advance,
R

Re: [Pharo-dev] Detect when Pharo loses focus

[roberto.mine...@usi.ch]

I wasn’t able to find something like that.

There is MorphLostFocus, bit is not triggered by World. And not triggered when 
Pharo loose focus.

Cheers,
R

[Pharo-dev] #runOnce: of StartupAction not working

[roberto.mine...@usi.ch]

Hi,

I am playing with StartupAction’s. I discovered that the #runOnce: message is 
apparently not working.

Try to put this (https://dl.dropboxusercontent.com/u/6281855/pincopallino.st) 
StartupAction into ~/Library/Preferences/pharo and open an image.

The first time the name is set as expected. Then, change the ‘PincoPallino' 
name in the pincopallino.st file to another name, save and open another time 
your image.

I think it should change the name again, since #runOnce: is set to false. But 
it does not.

Looking around seems that the StartupLoader handles the preferences in a 
Dictionary whose keys are names (BAD) and if there is a preference with the 
same name of an already executed one it does not re-execute even though 
#runOnce: false.

I also put an entry in the tracker: 
https://pharo.fogbugz.com/f/cases/12594/runOnce-of-StartupAction-not-working

Re: [Pharo-dev] PharoLauncher as the default Pharo download on pharo.org?

I like the launcher, I’ll use it for sure by myself even though it will not be

Re: [Pharo-dev] gtinspector deconstructed

[roberto.mine...@usi.ch]

Hi Doru,

I have never used it till 2 days ago when I was playing with Andrei to do 
something.

The only thing I can say is that it “feels” strange at the beginning… I am not 
used to this horizontal navigation… I am more used to spawning a lot of small 
inspectors that I can also use to compare things, i.e., one inspector close to 
the other.

Apart from that, Andrei told me it takes time but then you get used to it and 
you love it. Let’s see.

Cheers,
R

 Hi,
 
 I took a bit of time to describe how the GTInspector works, what makes it 
 different, and to provide hints for several usage scenarios.
 http://www.humane-assessment.com/blog/the-moldable-gtinspector-deconstructed
 
 It's a long post, I know :), but please take a look. As you might know, this 
 is the default inspector in the Moose image, but it can also be loaded in a 
 fresh Pharo image.
 
 I am particularly interested in the following:
 - if you never used it, and tried it now, what don't you like?
 - if you used it, was there anything that you did not know?
 - and of course, what do you like about it?

[Pharo-dev] Menu enabled not refreshing

[roberto.mine...@usi.ch]

Hi,

I think I spotted a bug. When registering a menu item I think the message 
PragmaMenuAndShortcutRegistration#enabled: passing a block is not working 
correctly.

It seems that the enabled state is somewhat cached, i.e., if the block value 
passes from true to false due to a certain condition in the model, the enabled 
state is not changed.

Are you aware of this? Am I missing something (i.e., force the refresh or 
something).

Thanks in advance,
Roby

[Pharo-dev] [Edu] 3-day project with high school students

[roberto.mine...@usi.ch]

Hi,

I would like to hear an opinion from you. I need to organize a 3-day project 
with high-school students. In short they will come to our University and I am 
the responsible to guide them to do “something” to introduce them to 
programming.

The assumption is that they have zero background about programming. In this 
mailing list I’ve read a couple of previous discussions about how to start to 
use Pharo and ST for educational purposes, but I’d love to collect additional 
opinions.

Visual programming is one of the thing that came to my mind. I though about 
Phratch. Michele suggested me to look also at Etoys (squeakland.org) and I will 
start to look at thesee two tools in the next days.

Any opinion, proposal, tool, article, suggestion, hint on the topic is really 
welcome.

Thanks in advance,
Roberto

Guys,

Fuel it’s perfect, it was–of course–my fault.

When I considered everything and I moved away from Ring definition which caused 
me lot of troubles I forgot to consider MethodContext objects, which in turn 
points to CompiledMethod which point to classes. Thus Fuel serialize all this 
crap (including classes) and in the materialization phase I got clearly a 
FLClassNotFound.

 Even in this case, Fuel should have not serialized classes. Instead, if a

 that just contains the class name and a few other things, but not the whole 
 class.

Nope, trust me it serialized the whole class.

 Then at materialization it should search that class name in the 
 SmalltalkDictionary and get that.

There is no such class at materialization.

 So...it could still happen that the class name you stored during 
 serialization is NOT present in materialization. But Fuel should not have 
 serialized the class itself but rather this mock object. 

Again, I removed the MethodContext and use a description for them, and 
everything work as expected.

[Pharo-dev] [Fuel] How to tell Fuel *not* to encode references?

[roberto.mine...@usi.ch]

Hi,

I’m struggling with Fuel and I probably discovered my problem.

When trying to serialize an object (that represents a development session, 
i.e., contains some meta-data (title, author, etc.) and some objects 
representing actions of the developer) I often encounter problem with some 
BlockClosure’s which are somewhat corrupt and Fuel crashes and cannot serialize 
them. We already discussed this issue in this mailing list a while ago with Max.

I do not ask directly Fuel to serialize some BlockClosures, so my intuition is 
that Fuel serializes all the references to the objects I am trying to 
serialize. Am I right? Is there any way to tell Fuel not to do so?

Cheers and thanks for the help,
Roberto

Re: [Pharo-dev] [Fuel] How to tell Fuel *not* to encode references?

Hi Martin,

Thanks for the answer, I have another question. Is there any way to tell Fuel 
to serialize only the object with its instance variables and that’s it?

I don’t want Fuel to traverse any reference, just the object with its fields.

Thanks,
Roberto

 So I think in some way your object is referencing that problematic block

 Maybe it can give you a clue if you put a halt in FLAnalysistrace:

 You might want to customize how your development session objects are 
 encoded. Like in DateAndTime... you can look at these methods:
  
 #fuelAccept:
 #serializeOn:
 #materializeFrom: (at class-side)
 
 
 Or you can tell fuel to ignore some instance variables, if you override 
 #fuelIgnoredInstanceVariableNames at class-side.
 
 Both alternatives are covered in the documentation 
 
 http://rmod.lille.inria.fr/web/pier/software/Fuel
 
 (which is sadly down in this moment, but will be up again soon)

  i.e., contains some meta-data (title, author, etc.) and some objects 
  representing actions of the developer) I often encounter problem with some 
  BlockClosure’s which are somewhat corrupt and Fuel crashes and cannot 
  serialize them. We already discussed this issue in this mailing list a 
  while ago with Max.
 
  I do not ask directly Fuel to serialize some BlockClosures, so my intuition 
  is that Fuel serializes all the references to the objects I am trying to 
  serialize. Am I right? Is there any way to tell Fuel not to do so?
 
  Cheers and thanks for the help,
  Roberto
 
 
 
 

Re: [Pharo-dev] [Fuel] How to tell Fuel *not* to encode references?

[roberto.mine...@usi.ch]

The idea is that I have an object (a session) which has meta data (time, 
duration, author) and some other object inside.

I want that Fuel serializes just that object and not pointes to other object, 
globals and what not.

This causes me a lot of troubles, moreover it makes the fuel file bigger than 
the optimum…

Cheers,
R

 Maybe it is something which is needed, what do you think?
 
 The idea is that, if you serialize:
 
 a - b - c
 
 fuel actually would encode:
 
 a - b - nil
 
 
 that?

 Hi,
 
 In my project, my code has a strange behavior when I'm reading all 
 subclasses of an another class.
 
 The following code must visit all the subclasses of PVEStatus but I get a 
 bad result.
 
   PVEStatus allSubclasses
   do: [ :statusDatatype |
   (aRawStatus at: 'type') = statusDatatype type
   ifTrue: [ ^ statusDatatype getStatus: 
 aRawStatus callback: self ] ]
 
 The answer contains #AnObsoletePVENodeStatus and this class doesn't exist. 
 She doesn't appear in the class browser. I suppose that it's a rest of 
 refactoring. How can I delete this obsolete class ?

 A description of mainly point 1. can be found here:

 I already used it as a splash screen for a couple of presentations, and it

 The code can be found in Moose, in a separate tiny FAMIXSystemAttraction

view := ROMondrianViewBuilder view: rawView

And then adding nodes to the view, calling view nodes: myNodes

 Hi,
 
 I was at ESUG last week and I discussed about this issue with some people, 
 and in the end Stef told me drop a mail in the mailing list, I am interested 
 to understand what all the other people think about it. So, here I am.
 
 I have my project in which I am modeling development sessions. Each session 
 object has a number of meta-data (e.g., start, end time, etc.) and a 
 collection of events. Each event object owns some meta-data and some 
 references to classes that were touched by a given event (i.e., now I am 
 using the Ring definition of the classes, since I plan to serialize and 
 deserialize them and I cannot serialize the real class object, it would be 
 too heavy, isn't it?).
 
 Serializing a class is not a big deal ;). With fuel you can even serialize 
 execution contexts, blocks and stuff. But (but but), I can tell your decision 
 is still good because during development you can end up removing a class, and 
 when that happens the system makes it obsolete and remove all its data.

Exactly the problem I run into.

 So if you were pointing to the real class, you would have problems to access 
 the class data afterwards. And since you use ring, you're ok ;).
 
 Cheers,
 Guille
  
 
 Now the question: I would like to create a Moose model of a development 
 session to be able to import the sessions in the Moose panel and play around 
 with the excellent Moose tool-suite. How should I proceed? Do you think it's 
 better to annotate and add pragmas to the existing classes or to create a 
 minimal parallel hierarchy of my model (i.e., MooseSession for MySession) and 
 have something like MySession#asMooseDef which returns an object of kind 
 MooseSession?

Any suggestion on this, Guillermo?

[Pharo-dev] [Fuel] [FuelMetaLevel] Help

[roberto.mine...@usi.ch]

Hi,

I am using Fuel to serialize/deserialize some objects. As part as the objects I 
need to serialize there are some classes, class definitions (i.e., Ring) and 
some CompiledMethod.
It's not always the case that I serialize and materialize in the same image, 
thus sometimes I experience FLClassNotFound and FLMerthodChanged exceptions.

I discovered FuelMetaLevel, as far as I can understand, it can solve many 
problems. 
Now my questions are (1) am I correct that it can help? and (2) from which 
repository should I load FuelMetaLevel?

As far as I understood not Fuel is developed as part of Pharo so it's 
pre-installed in every fresh image. I tried to get FuelMetaLevel from ss3 (both 
Pharo20 and PharoInbox) but when I run 
FLSerializer newFull serialize: 'whatever' toFileNamed: 'whatever.fuel'

I got a MNU on 
FLFullGlobalMapper#initializeWithInternalBehaviors:internalMethods:globalSymbols:
  since the class FLGlobalAssociationCluster is not part of my image.

I'm attaching the stack trace of the error I'm getting.

Thanks in advance,
RM

Thanks! I was not aware of a Fuel-dev mailing list.

Thanks,

Re: [Pharo-dev] Removing a package from Smalltalkhub

[roberto.mine...@usi.ch]

Awesome, you guys are fast!

A nice to have would also be a rename package and rename project without having 
to create a new project and/or a new package since in this way you will loose 
the history..

Cheers,
R

 nah, it is a known missing feature (and really needed), there is a fix coming 
 I think next week.
