Re: [Pharo-users] Class versions

[Stephane Ducasse]

What are multiple versions of a classes?

We are working on a module system for Pharo. The prototype is making
progress. You will be able to have different classes with the same name in
different classes.

Re: [Pharo-users] OSProcess or OSSubprocess?

[Hernán Morales Durand]

I just tested and it works nice!! Thank you Mariano.

Just a quick note, to read from /var/log requires root privilege which many
users cannot acquire. I tested using a bash script and then tailf the
output file:

#!/bin/sh

while true; do
  echo $(date)
  sleep 2
done > output.txt


Cheers,

Hernán

Hi,

Here is a slice that implements the  #argsAsArray option:

from a speed perspective, the question is if a dictionary makes sense… as it

[Pharo-users] read, display, and annotate MS Word and PDF files?

[David Epstein]

Hi folks. I am considering trying Pharo for a project but am unfamiliar with 
Smalltalk. I'm attracted by the close integration between language and IDE. Are 
there native libraries that would allow me to read, display, and annotate (e.g. 
add comments & highlighting) to MS Word and PDF files? If not, is it easy to 
call libraries intended for other languages, such as http://www.foxitsdk.com/ ?


Thank you,

I'm not frustrated, but I share the feeling that we're missing
valuable contributions from other users.

The thing with Magritte is that everything is done by subclassing, the
metamodel part (MADescription subclasses) is pretty composable, but
the seaside components are bound to whatever CSS framework is chosen,
there isn't much to do there other than subclassing. This has several
drawbacks to integrate code from different teams/projects, because you
end up having to use a whole set of classes from the "foreign" library
(e.g. QCMagritte) rather than just a few components.

One thing that I disliked is the fact that from Magritte 2 to 3 the
descriptions moved from the class side to the instance side, to allow
dynamic containers based on instance state/behavior, this is really
powerful, but I'd preferred a two step lookup to build the instances,
it is... look at the instance side first, and then class side, this
way you can manipulate description without having to instantiate a
sample instance. This is mandatory if you're building an UI like a
reporting, querying tool where do not know in advance which instances
are going to be returned.

However I think this is a discussion for the Magritte, or Seaside, mailing list.

Hi Hernan,

There is a tail -f example in OSSubprocess documentation that prints the
result on an inpsector and updates it [1]. However, OSSubprocess has
problems on Linux with the default VM... you must use the threaded
heartbeat (not the itimer).. see recent threads discussions for this.

Let me know if that works.

GitFileTree does fetch partial output over OSProcess, but this is quite a
low-level use of OSProcess.

What is missing is true pseudo-tty support.

Re: [Pharo-users] Magritte extension

[Otto Behrens]

Hi,

We also made several sub-classes of Magritte classes and / or
components. This causes a lot of problems because when we upgraded
Magritte it was difficult. It also shows that Magritte (the core
classes) cannot change much because the impact will be high for most
users of Magritte. This makes us think that Magritte is not easy to
use or customise. And it also appears as if all the custom changes are
not being generalised into the framework. Perhaps us users of Magritte
should stand back and discuss our changes and issues more so that we
can improve it? I suppose we need some magritte champion(s) to take it
somewhere.

To get more flexibility with Magritte styling we are using CSS and
classes more in stead of rendering in a different way. Often one can
get away with adding a CSS class and changing the style sheet.

This is a bit fluffy, but it there's a lot of stuff to talk about
here. In principle, are you sharing my frustration with Magritte?

Re: [Pharo-users] looking for tools to manually select ast nodes for metalinks

[Guillermo Polito]

Hi Steven,

Yes there is! It's called "Suggestions". Suggestions is a project started
some years ago by Gisela Decuzzi as an intern of RMoD. The main idea is to
propose actions based on the AST corresponding to the cursor. This means
that given the position of the cursor, suggestions already:

 - parses the code
 - selects the corresponding node
 - provides possible actions for the node. E.g.,
- refactorings
- code navigation
- breakpoints and watchpoints (through Metalinks)

Check the SmartSuggestions package.

Thanks Mariano for the ideas. I will put them into practice. Then All I

[Pharo-users] OSProcess or OSSubprocess?

[Hernán Morales Durand]

Hi guys,

I need to monitor Unix command execution inside the image. The commands use
heavy computation so they usually report progress in the terminal.

Are OSProcess or OSSubprocess ready to do in-image monitoring so I can
watch the same terminal output in the Transcript updating for example every
10 seconds?

Particularly for OSProcess I couldn't find any method to fetch partial
output.

Cheers,

Hernán

[Pharo-users] TextInspectIt missing in Pharo 6

[Alistair Grant]

Hi All,

TextInspectit and TextDoIt>>rubActOnClick:for:in:editor:, which are part
of the Text-Core package, are present in Pharo 5 but not in Pharo 6
(60442).  All the other classes in Text-Core appear to be present (I
haven't checked every method).

Is this intentional, and if so, what is the replacement?

Thanks very much,
Alistair
