Re: [Pharo-users] ZipFileMember>>contentStream has leading characters

by Tudor Girba

You are likely referring to the issue reported here: https://pharo.fogbugz.com/f/cases/12826/Zip-FileSystem-does-not-work This should work now in the latest Pharo 4.0. If you are using Pharo 3.0, loading the slice manually from the Pharo40Inbox should fix the issue as well. What version are you using?

Re: [Pharo-users] source code

by kilon alios

I am not aware of tools that do this inside pharo (I am also using pharo for only a year now) but you can do this via code for example lets say you want to see the source code for TaskbarMorph both instance and class methods you can use this code to output the source code to the transcript Transcript clear. Transcript show:'***********INSTANCE SIDE*********';cr. (TaskbarMorph methods) do:[:each| Transcript show:each sourceCode;cr;show:'---------------------';cr]. Transcript show:'***********CLASS SIDE*********';cr. (TaskbarMorph class methods) do:[:each| Transcript show:each sourceCode;cr;show:'---------------------';cr]. Alternatively you can file out a source file for the class which will be saved in the pharo folder with a st file extension. You just right click on the class (in system browser) and choose file out. For sharing code you use monticello and either smalltalkhub or git/github. I use github personally.

Re: [Pharo-users] source code

Erik, for your collaborators, using a scm tool like Monticello is probably the best you can do. To print a class in your papers, you can probably get there fastest by doing a fileOut of your class(es) and import the resulting .st file into your word processor. There will be a lot of exclamation marks and stuff that make the .st file easier to parse, so you may want to edit the fileout before "citing" your code. hth, Joachim Am 13.10.14 um 11:32 schrieb Erik Itter: > Hello, > > being new to Smalltalk I wonder how I exchange source code both with > collaborators and with my papers.

Hello, being new to Smalltalk I wonder how I exchange source code both with collaborators and with my papers. Is there any view on the code basis where I see the complete class I wrote in order to use the source code in my papers without the need to collect pieces from the individual methods? best regards Erik

Re: [Pharo-users] Reloading a shared c library after been modified?

by ClÃ©ment Bera

Hello, this is possible but non trivial. I think the easiest way is to bind the C functions to manage C libraries: dlopen, dlsym, dlclose, dlerror. Then you can manually open and close the dynamic libs (dlopen, dlclose) and call the function dynamically loaded with dlsym. dlerror is used for error handling (else you don't know why your call failed).
