OSProcess?
by Alexandre Bergel 25 Jul '06

25 Jul '06

Hello, I would like to launch the unix/cygwin make command within Squeak It seems that OSProcess would help in doing it. But I run into troubles. when I doit: OSProcess command: 'ls -l /etc' I got a rollback. The following "self initialStdErr nextPutAll: 'cannot execute ', self commandLine" tried to be executed. I installed OSProcess, OSProcess plugins and CommandLauncher. Is there anything supposed to be obvious that I missed ? The file Win32OSProcessPlugin.dll is in the same directory than the VM and the image. Note: I am using Windows XP, cygwin and Squeak 7035. Help would be highly appreciated...

by Peace Jerome 25 Jul '06

So that we might follow the topics on Squeak-Dev as easily as possible. Please keep threads as on topic as possible. Please, when your post verges off the main thread topic please start a new or varient thread. Please also, start a varient thread if you start to address the solution to the problem at a much greater depth than the original thread called for.

by Hans N Beck 24 Jul '06

24 Jul '06

Hi, Marcus Denker has suggested to make an entry at http://www.squeak.org/ Community/Teams for our Software Engineering Team. Great ! For this, a team leader and a cooperator should be pointed out :-) If possible, I would like to make the team leader :-) But of course, if any other has better suggestions .... ;-) The entry I suggest would be: Name: Software Engineering Team Description: Developing software engineering tools in and for (but not only for) squeak Regards Hans

My little experiment on Squeak3.9b-7044 using WAKom without any conversion: - seaside input method works correctly and the model get the right value (at least, if I inspect it in squeak I get the right accented character) - during the answering, the WAResponse contained the valid accented character printable within Squeak debugger - the only problem is in html source code I can read in my web browser. There is a '?' instead of the letter. What is the encoding used by Squeak3.9b-7044 ? It seems to be UTF-8 because WAKom does not convert anything if I understand correctely. Can somebody help me and make accented characters work on Seaside ?
