help with petitparser in Pharo 2.0
by Miguel Enrique Campusano Araya Aug. 8, 2012

Aug. 8, 2012

Hey this is my first mail, hope you can understand my english :) I was playing a bit with Pharo 2.0 and i tried to load PetitParser on it but I couldn't. The problem is that the version PetitParser-lr.228 of PetitParser depends on BlockContext. This class was removed from Pharo 2.0 but it was present on Pharo 1.4, so PetitParser works well on Pharo 1.4. Is there a possibility to use PetitParser in Pharo 2.0 now? something that am I overlooking? or maybe there is a possibility to use PetitParser in Pharo 2.0 in the future? Thanks in advance :) -- Miguel Enrique Campusano Araya Student of Computer Engineering Universidad de Chile

Debugging block with ensure block
by kurs.jan Aug. 7, 2012

Hi, I observe a strange behaviour (in Pharo-1.4-14557-one-click.app) while debugging the following code. [ | a | self halt. a := (1 == 1). a ifTrue: [ ^ 'A'] . Transcript crShow: 'foo'. ^ 'B' ] ensure: [ Transcript crShow: 'bar'. ] If I comment out the halt statement and if I inspect the result of the attached code, the 'A' is returned and there is a 'bar' text in the transcript. If I inspect the result of the attached code (with halt enabled) and if I click step over in a debugger, I can see, that the statement ^ 'A' does NOT return, the program flow continues on the next line and the 'foo' is shown in the transcript. Now, I can click proceed and the 'B' is returned as a result. I tried the same process in Pharo-1.3-13328-OneClick.app and I got 'A' result in both cases. I tried on this system: System Version: Mac OS X 10.7.3 (11D2001) Kernel Version: Darwin 11.3.0 Regards, Jan -- View this message in context: http://forum.world.st/Debugging-block-with-ensure-block-tp4641279.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Error when committing on SmalltalkHub
by Francois Stephany Aug. 7, 2012

Aug. 7, 2012

I get a ZnResponse(400 Bad Request text/html 512B) when trying to push on SmalltalkHub from the Monticello Browser in 1.4 Am I the only one experiencing the issue? I navigate a bit on Smalltalkhub to see if it is possible to manually upload from the web but it seems that the feature does not exist.

New feature in Nautilus
by Benjamin Aug. 6, 2012

Aug. 6, 2012

Hello guys :) I just wanted to show you the new feature I just finished to implement into Nautilus: the multi methods edition http://dl.dropbox.com/u/24369478/MultiMethods.mov The video is quite short (1min) but it will be integrated soon in the image so ;) Some explanation: - now you can "pin" a text area, it will "freeze" the context, so you can edit it and save it without problems - you can have a many as wanted - the scroll pane is a bit clever to always keep the maximum size for the current edition (but there are splitters, so you can set it as you want) - you can "unpin" a text area, and it closes it (to add: check if there are pending changes) - the glitch about the color is the video has been fixed already (but I am too lazy to make another video ^^) - the frozen area get a help text which tells the method the source code comes from - the corresponding button have the same help text - clicking on the button jump to the method I hope you will enjoy it, and as usual if you have cool ideas, let me know ;) Ben

Display issue v1.4 & V2 vs V1.2.1
by Joshua Panar Aug. 4, 2012

Aug. 4, 2012

Apologies if this is not new, and please direct me to the appropriate message (or forum). I recently wrote a small Game Of Life program running in Pharo V1.2.1 which shows a glider changing shape (and hence position) as the iterations are performed. However, same code running in V1.4 (also in V2) only displays the *final* glider position. This is on Mac Lion. Putting in code to stop execution midway through the iterations leaves the correct glider shape and position displayed (for the point the iterations were stopped), so code seems to be executing ok ... just not continuously displaying. It appears as though display is being disabled until code execution ends?? Any suggestions how to restore the visible progression of the glider as the code executes? Tnx, Josh -- View this message in context: http://forum.world.st/Display-issue-v1-4-V2-vs-V1-2-1-tp4643069.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Zinc downloadTo: help required
by Chris Aug. 3, 2012

Aug. 3, 2012

I'm trying to do a wget style download with Zinc but running into a few problems when a server uses chunked transfer encoding. Eventually it ends up in ZnUtils streamFrom:to:size: with an empty totalSize (as content-length is unset) and then produces an empty file. However the download works fine if I simply do an upToEnd on the ZnChunkedReadStream. This can be seen by executing ZnClient new url: 'http://www.google.com'; downloadTo: '/tmp/foo.txt'. Thanks Chris

iterating through an ascii file by line
by Paul DeBruicker Aug. 3, 2012

Aug. 3, 2012

Hi - Is there an easy/standard way to open an ascii file and iterate through it line by line? I want to put several files contents into their own OrderedCollections and then do awful things to them. The files are ~500MB each Thanks Paul

How do you guys navigate while editing code?
by Patrik Sundberg Aug. 1, 2012

Aug. 1, 2012

Hi, Jumping in as a smalltalk beginner I am, as one would expect, feeling frustrated by not knowing my way around. Can see lots of cool stuff but all the mouse action is killing me. I'm a vim(+tmux) guy by background so the contrast is vast, I usually never need to touch my mouse when programming. I was trying to find some keyboard shortcuts to do things like "jump to method within class with fuzzy search logic" (type a few characters and get list etc) or "jump to the method/class under which the cursor is located". The jump to selected needs text selection which seems really awkward (even when selecting with keyboard), my 90% case is to jump to what's under the cursor. The global find class and find methods are good, but most of the time I'm interested in "local" navigation in the current class while jumping back and forth between methods in same class. I find more things in Nautilus since I can list the shortcuts there, but quite a few doesn't seem to work and I'm not having much luck using nautilus in 1.4 (and 2.0 too edgy for me right now, need metacello to load things cleanly etc at least). In OB in 1.4 I'm not able to figure out how to get a list of shortcuts apart from what's annotated in menus Guess my question is - how does a keyboard centric person like me learn keyboard shortcuts and get productive in the image, more specifically 1.4 and OB? How can I work out what keyboard shortcuts exist? Thanks!
