[Pharo-dev] Question on AioPlugin

[Thierry Goubier]

Hi all,

anybody knows how to check if the AioPlugin is included in the current
stable Pharo vm(*)? OSProcess is complaining of a missing AioPlugin, and I
remember a thread where this was solved by integrating it in the vm build.

Thanks,

Thierry

another possibility on OS X is to put the correct path in .bashrc and then
start Pharo from a Terminal via the command 'open Pharo.app'.
Adjust Pharo.app to the name of the Pharo application bundle on your
machine.
This is not a perfect solution but it works.

There is also a special file on OS X where you supposedly can add things
like a $PATH variable for graphical programs.
Unfortunately I don't remember the name of that file.

Best,
Manfred

Ok, tell me how it goes. OSProcess/CommandShell has options and examples to
retrieve and extend the path before calling an external function, so this
may also be a way to solve it.

A third one would be to download a git static executable along with the
GitFileTree support.

Thanks. 
By the way, for this specific case (run Pharo from UI), I still think it should 
be configurable with the OS (from some profile file) but I did not find a 
solution yet. 
Another option could be to retrieve the content of path variable with 
NativeBoost and use it to run the git command. I will test.

Re: [Pharo-dev] Overwrite repository in symbolic version

Yes, I do the same, although instead of using \ I wrap my command in double

This is fixed in Pharo4 (I think we did that in Pharo3 already):

I should search the issue in the issue tracker… it seems to be Pharo4, so just 
1296 closed issues to check there…
I will search for it.

Another question: In the code I saw. ReadOnlyVariableBinding. I removed that in 
Pharo relatively early as it was not used:
half of the classes were stored that binding (old ones) all newer ones where 
just associations.
The code to make a binding "read only" was never called.

Is this now used in Squeak? Is it worth the complexity?


Squeak doesn't use ReadOnlyVariableBinding anymore. The bindings of 
classes are instances of the ClassBinding class.
Without using separate class it's a bit cumbersome (and less OO) to decide 
if an assignment to a global variable should be allowed or not. E.g.:


Foo := 1.

should work if Foo is a global, but not a behavior. It should raise an 
error if it's a behavior.

Re: [Pharo-dev] GitFileTree - Git command not found (is which shell startup script is run when pharo launched from UI)

[Thierry Goubier]

Hi Christophe,

looks like that a configuration option for the path to the git command is
necessary :) https://github.com/dalehenrich/filetree/issues/143

I'm planning a bit of a rewrite for GitFileTree (saw a few significant
issues on Monticello to git integration pop-up recently) and I'll add that
along with the others.

Re: [Pharo-dev] Overwrite repository in symbolic version

[Thierry Goubier]

I do on the command line the following:

pharo Pharo.image eval --save Metacello new baseline: \'MyProject\'\;
repository: \'github://\'\; load

The \ are a bit annoying, but it gives you access to any smalltalk cod,
which is very convenient.

Ah, there is also NaN (not a number).

So, float can be:
NegativeInfinity
a Finite Float
Infinity (;positive by elimination)
NaN

Oh, and NegativeZero as well.

floats are weird.

Re: [Pharo-dev] can a Float be not finite and not equals to Float class>>#infinity ?

[Esteban Lorenzano]

in fact, I wonder why #isFinite is implemented: 

^(self - self) = 0.0

and not just:

^self isInfinite not

which includes the negativeInfinity…

Re: [Pharo-dev] can a Float be not finite and not equals to Float class>>#infinity ?

[Chris Cunningham]

There is Float infinity and Float negativeInfinity - two infinite classes.

Can I assume your first test really wanted to be:

aFloat isFinite = false
?

Hi,

aFloat isFinite = true

and 

(aFloat == Float infinite) = false

is a possible combination

Re: [Pharo-dev] GitFileTree - Git command not found (is which shell startup script is run when pharo launched from UI)

[Peter Uhnák]

Hi,

Both .bashrc and .bash_profile are directly bound to shell (bash shell) so
this will not help. I do not know MacOS, so I'm not sure if there is some
GUI configuration like in MS Windows, so someone else might clarify.

In the meantime there is also an alternative way - create a custom launcher
where you set the path explicitly... i.e. PATH=$PATH:/usr/local/bin ./pharo
pharo.image (or however you start your pharo instance).

[Pharo-dev] GitFileTree - Git command not found (is which shell startup script is run when pharo launched from UI)

[Christophe Demarey]

Hi,

I wanted to give a try to gitfiletree but I got a 'Git command not found'.
Indeed, the git command is not in the path Here is the code used by GitFileTree 
to run a git command:

| c output |
[ 
c := PipeableOSProcess
command: 'export'.
output := ReadStream on: c output.
c succeeded
ifFalse: [ self error: 'Git error: ' , c errorPipelineContents 
] ]
ensure: [ c closePipes ].
output

I replaced the command to execute by 'export' to get all environment variables. 
I noticed that '/usr/local/bin' is not in the path (used by brew).


To get my full environment (.profile executed), I need to run pharo from a 
shell with the same environment. The question is: how to run Pharo from the UI 
and get this environment?
I tried with a .bashrc, bash_profile without success.
Any idea?

Thanks,
Christophe.

[Pharo-dev] Monospaced font

[KasperOsterbye]

And no, I do not want to restart the discussion of the (lack of) qualities
regarding such fonts. 

It is just not clear to me how to get hold of a font. 
It seems like at the one hand it is all 'Bitmap deja vu sans regular'. 

In the settings browser I can pick all kinds of fonts, but it is unclear how
I get a reference to them as I do not want to install the font as default or
code fonts, but just need to apply the font to a few words in a Text object. 

If I try to ask for StrikeFont for say 'Courier' I get 'Bitmap deja vu sans
regular'. 

Where is the magic hidden? 

A perhaps related question is if one can apply subscript and superscript to
the regular Text attributes - I have not been able to find that either. 

Best, Kasper

The part in between Pharo3 and Pharo4 tries a bit to explain the philosophy… I 
did a longer
talk at ESUG last year about that:

Nomads do not build Cathedrals
http://www.slideshare.net/MarcusDenker/2014-esugcathedral

The video of that is online:

Video Part 1: https://www.youtube.com/watch?v=Vcoy5gwUvOA 
Video Part 2: https://www.youtube.com/watch?v=5LrH9r4FNzY

In the spirit of the talk, I should do a pass over it and make a version 2…

e.g. one book that was very influential to my thinking was
Finite and Infinite Games by James P. Carse:

http://kk.org/cooltools/archives/000434

To me a software system should always be thought as an “infinite game”…

Yes, I’ve reported that already and it was fixed in Pharo 4

It was recorded… the Q&A after was not that many questions… I don’t actually 
remember.

I think the impact is more the slides+video, not the presentation itself there.
