Re: [Pharo-users] Pharo Launcher and 64bit VM

I'm using 64bit OS for quite some time (aka years) and consider it's

Yeap no doubt there, 64 bit programming languages are pretty much the
standard. I am definitely a supporter of moving to 64 bit and from the
looks of it , maybe I should give 64 bit pharo a try myself, I thought it
was not quite ready yet. Glad I am wrong.

every choice and nonetheless coding in pharo is still a joy for me :)

"
I never heard of this disadvantage of 64 bits before. Are you basically
saing you can't run multiple instances of a 64-bit VM/Image on a
multicore machine?
Can you elaborate?

"

Yeah I should have been more clear, no I am not saying that 64-bit VM
cannot do this. I was talking about multiple 32 bit pharo instances against
a single 64 bit pharo instance. A unfair comparison but I was just trying
to make a point.

This ability of multiple instances running on multiple cores is not even a
VM feature, its just normal process handling of the OS. The OS assign each
process to a different core to take better advantage of the processing
power of the CPU.

I do not know where the project is hosted.
May be esteban knows because he was maintaining Pier.

Re: [Pharo-users] Mustache and section

[Norbert Hartl]

I agree. But there is also a point in sharing mustache templates between  
different runtimes. Altering mustache does not make it very mustache anymore. 
And it will make it slower. I put that on my ever growing list of things to do. 
Maybe a switch could bring the best of both worlds.

I think it is known. But there seem to be more problems in the debugger when

My use case is that sometimes I need/want to view the file with my eyes, and 
when in 95% of the file the content is single (or couple words), then quotes 
add a lot of clutter. So if in 5% (or 1%) of the file there are quotes and the 
reset aren't, then I would be happy. :)

But it's not such a big problem, I've added it for myself, at least until we 
will have a usable way to edit CSV files in Pharo... do we really not have any 
table editor? :/

OK, but what i need to do for load UFFI Cairo library

and for load  the UFFI  library  required byGitFileTree Pharo 
support?


I wrong to install Pharo 5.0 on my MacBookPro with OS X  10.7.5. ?

If right remember i install Pharo 5.0 from   
http://pharo.org/download   link


Thanks.

Re: [Pharo-users] GitFileTree on Pharo 5.0

[Esteban Lorenzano]

Hi, Dario, 

I do not understand quite well your problem… you should not have a problem 
installing GitFileTree in Pharo5, no matter the replacement of NativeBoost. 
Athens also works fine with UFFI (since is part of Pharo, it has to work on all 
versions). 

You *do not need* to download cairo bindings, they are already there. 
So… if Athens is not working (and you can check that executing "VGTigerDemo 
runDemo” ,  then you have another kind of problem. 

cheers, 
Esteban

Re: [Pharo-users] GitFileTree on Pharo 5.0

[Dimitris Chloupis]

If you go to the applications there is a folder called Utilities and inside
it there is a terminal application open it and issue the following commands

mkdir pharo
cd pharo
curl get.pharo.org | bash
./pharo-ui Pharo.image

First command will make folder, second will enter the folder, third will
dowload the standard stable version of pharo to the folder, foruth will
launch pharo.

Then when pharo opens follow the instruction Esteban gave you to test that
Athens works as it should. Do not install anything before testings. Then if
everything works proceed and install one thing, only, then test it, then
install the next one etc.

Moving step by step will help us pin point your problem

I suspect maybe something went crazy , it happens from time to time in
pharo, recently I had a nasty corruption with Pharo 6. If it happens once,
its ok , if it happens frequently its a problem.

What do you mean about : another kind of problem.

How can I investigate about that?

Download again the image and see what happens?

hi Dario,

Reading back through the thread, it seems it works when you start
Pharo one way, but not another way.
Can you report the VM versions for each way..
World menu > System > System Reporter > VM General

Is one of those ways you start Pharo is using Pharo Launcher?
In the settings you can point it to a new VM you download.

[Pharo-users] accessing local/instance variables with metalinks

[Peter Uhnak]

Hi,

what is the best way to access variables from within a metalink?

for example I have a message send `surface clear` and I want to change it to 
`surface clear: trachelCanvas color`.

I can use #instVarNamed:

```
MetaLink new
metaObject: [ :object |
(object instVarNamed: #surface) clear: (object instVarNamed: 
#trachelCanvas) color.
];
selector: #value:;
arguments: #(object);
control: #instead.
```

but the above isn't exactly nice, plus it wouldn't work with temporary 
variables.

Thanks,
Peter

Can you expand on the problem.
"(Delay forMilliseconds: 500)wait." looks fine to me.

Re: [Pharo-users] GitFileTree on Pharo 5.0

[Andrew Glynn]

I run Pharo 5.0 with no problems on a Macbook Pro, but it’s running OS X v. 
10.12.1.  Any reason your OS is backdated?

Ciao,



Pharo is unable to access a library it needs; this is the native boost plugin 
which is normally bundled with it (and the cairo lib?)...

 

Guys, anybody with a mac around there?

Thierry

 

 

    thanks Dimitris.



Nativeboost has been removed and been replaced by UFFI, all libraries that used 
Nativeboost are now using UFFI including the Cairo backend library for Athens.

 

    OK,     but what i need to do for load UFFI Cairo 
library

 

    and for load  the UFFI  library  required by     GitFileTree Pharo 
support?

 

 

    I wrong to install Pharo 5.0 on my MacBookPro with OS X   10.7.5. ?

 

    If right remember i install Pharo 5.0 from     
http://pharo.org/download   link

 


    Thanks.
