Hi Eliot, at [1] you mentioned a port of MethodWrappers to Squeak 4.2. Is there also a port for Pharo available or do you plan to port it? For those who dont know about MethodWrappers: look at [2] Thanks Torsten [1] http://lists.squeakfoundation.org/pipermail/squeak-dev/2011-September/16156… [2] http://www.refactory.com/Software/MethodWrappers/ -- NEU: FreePhone - 0ct/min Handyspartarif mit Geld-zurÃ¼ck-Garantie!

[Pharo-project] Bug in DateAndTime?
by Max Leske March 27, 2012

March 27, 2012

Hi. Evaluating: DateAndTime now asUnixTime and then creating a DateAndTime object from the result: DateAndTime fromUnixTime: <seconds> does not yield an equivalent object. As far as I can tell, this is because the unix epoch is hard coded in two places: DateAndTime class>>unixEpoch "Answer a DateAndTime representing the Unix epoch (1 January 1970, midnight UTC)" ^ self basicNew ticks: #(2440588 0 0) offset: Duration zero; yourself. DateAndTime>>fromUnixTime: anInteger ^ self fromSeconds: anInteger + 2177452800 "unix epoch constant" So in the end I get a difference of 7200 seconds. I'll gladly open up a bug but can someone please confirm that this is actually a bug and that I didn't miss something? Cheers, Max

[Pharo-project] how to get a string read stream from filesystem
by Tudor Girba March 27, 2012

March 27, 2012

Hi, I am using Filesystem, and I would like to get a read stream that provides a string instead of bytes. If I do "aReference readStream", I get a FSReadStream which is a byte stream. To get to the string, I now do the ugly: "aReference readStream contents asString" Is there a cleverer way? Cheers, Doru -- www.tudorgirba.com "What we can governs what we wish."

[Pharo-project] SystemTracer
by Benjamin March 15, 2012

March 15, 2012

Hello guys, for one of my projects, I'm trying to use SystemTracer to create anew image, but it appears that it doesn't work on Pharo ... I can create a new image, but I can't open it. I've tried with an older VM (Squeak 3.8.18beta1U), but it's the same ... Did someone already have this problem ? Does someone have a solution ? Thanks in advance, Ben

[Pharo-project] Misc. newbie questions
by Gerry Weaver Feb. 27, 2012

Feb. 27, 2012

Hello All, Firstly, let me say that I am enjoying Pharo very much at this point. I wish I would have found the time to look at this a long time ago. I have a few misc. newbie questions.Â 1. VisualWorks - I am doing a lot of thinking about projects that I could use Smalltalk on. I have a consulting project coming up that might be a good candidate, but I'm sure I would be required to use a commercial Smalltalk version for it. I guess it may be odd to ask about VisualWorks on this list, but I'm not really looking for a comparison to Pharo. What I'm interested in is your opinion of the product. I would like to know if any of you would consider using it on a project. I would appreciate anything y'all could share in the form of experiences good or bad. I am trying to get my hands on it, but Cincom's mail server (windoze) is having issues. I am also having some trouble getting pricing out of them. Anyway, I would like to get your take on the Cincom products. 2. There appear to be some tool choices in the Pharo image. I would like to be able to create a class and it's methods in an editor in one go. I like being able to see all of the class code at once. Is there a way to do this? Â I just want to be able to type it all in and accept (evaluate?) all at once. 3. I've seen some discussion about images and image sizes. What is the current state of this. Is it possible to strip an image down to just the required components for an application (ie; no world menu, etc.). I would like to be able to run an image that would bring my gui application up filling the image window such that it looks a close as possible to a conventional gui application. 4. I have been reading about something called "Opentalk". It is a way for images to be able to comminucate with each other over the network. I've also seen something callesd "rST" that appears to do a similar thing. In addition, I notice that someone has done some FFI bindings for zeromq. What would y'all recommend as the best option to achieve something like this in Pharo? 5. I'm trying to figure out exactly what the Pharo gui toolkit provides in the way of widgets. Is there a widget gallery type thing somewhere that shows all of them? I know I can play with them in the image, but it would be nice to see a list of what is there with a brief description. 6. I know Pharo doesn't currently support OS threads in an image, but I'm wondering about the FFI. Is it possible to call a foreign function in a separate OS thread or asynchronously in Pharo? Disclaimer: I'm not asking for any how to type answers here. I can do the reading and experimentation myself. I just want to know if these things are possible and where to start looking for a solution.Â Thanks, Gerry

Re: [Pharo-project] New IDE alternative (was Misc. newbie questions)

Dennis, your screenshots are awesome, hope remains for a direct manipulation framework such as Morphic to beet lesser and boring standard UI WIDGETS frameworks. And by the way, Morphic isnt ours..it comes from a groundbreaking object-focused environment called SELF.

Hi, my image got broken and I think I know (thanks to the dump) what I should change. But it won't load so I need to modify the image file from the outside world. Is there any way? Cheers, Javier. -- Lic. Javier PimÃ¡s Ciudad de Buenos Aires

[Pharo-project] Marking methods
by Bernat Romagosa Feb. 20, 2012

Feb. 20, 2012

Hi list, I've been thinking for a while that it'd be great if we could somehow graphically mark methods in the browser. Like adding an icon next to their name or highlighting them in different colors. When reviewing code, I find myself going through methods and would love to be able to mark them once they've been reviewed, to prevent me from going through them again. Does anyone else have the same needs? How do you guys manage this? I thought about flagging methods, but that'd mean I'd have to read through all my methods again to remove the flags once I'm done with the revision. Cheers, -- Bernat Romagosa.
