Yes you can either pass a st file as argument. See the recent mail of alberto bachelli or you can use Coral http://rmod.lille.inria.fr/coral/ Stef On Nov 20, 2011, at 6:08 PM, t olschewski wrote: > is there a standard way of using pharo 1.3 OneClick (or squeak 4.2 > All-in-One) for scripting tasks ? > > With python, I simply: > > * write a script foo.py > * use extra classes by writing "import xyz" > * run "python foo.py" > or even simpler: > * #!/usr/bin/python > > > > -- > View this message in context: http://forum.world.st/scripting-pharo-tp4089006p4089006.html > Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com. >

Hi Dave, Ok! I'll try to get it work... Yep 'less' was an example, I'm actually wrapping the exiftool perl library... Francois On Nov 20, 2011 6:30 AM, "David T.

scripting pharo

by t olschewski

is there a standard way of using pharo 1.3 OneClick (or squeak 4.2 All-in-One) for scripting tasks ? With python, I simply: * write a script foo.py * use extra classes by writing "import xyz" * run "python foo.py" or even simpler: * #!/usr/bin/python -- View this message in context: http://forum.world.st/scripting-pharo-tp4089006p4089006.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Francois, The output of the PipeableOSProcess is based on a StandardFileStream rather than a MultiByteFileStream, so it may not do what you expect with a file containing non-ascii characters. Note that the unix /usr/bin/less utility is intended for interactive use with a terminal. You probably should use /usr/bin/cat instead. HTH, Dave

OSProcess reading utf8 files

by Francois Stephany

Hi, Reading an utf8 file with OSProcess results in some weird characters showing up. (PipeableOSProcess command: 'less /path/to/a/text/file') output. -> inspect the bytestring and get some non-ascii characters fucked up. Doing `less /path/to/a/text/file` in a terminal displays the file fine. That's probably something stupid on my side but I cannot get it working. Any idea ? Cheers, Francois

Something like XDV/Diazo/Deliverance in Smalltalk?

by Offray Vladimir Luna CÃ¡rdenas

Hi, Me and a group of friends in a local hackerspace[1] want to intervene the interface of this Cynin site using the technologies of Diazo[2], Xdv[3] or Deliverance[4]. Seeing the way that views are wrote in Seaside I wondder if there is someway to make a similar intervention/integration of interface without touching directly the code a la Diazo/XDV/Deliverance but using Seaside/Zinc or some similar combination. [1] http://hackbo.co/ [2] http://diazo.org/index.html [3] http://www.enfoldsystems.com/software/proxy/docs/6.0/xdvtutorial.html [4] http://packages.python.org/Deliverance/ Any pointer will be appreciated. Cheers, Offray

Re: [Pharo-users] Changing Cherokee for a Smalltalk based web server?

by Offray Vladimir Luna CÃ¡rdenas

Hi, Thanks StÃ©phane and Sven. I think that I will opt for lighttpd or Nginx as a front end for Zope/Rails/Seaside-Pier inmy attempts to solve the "504 gateway error" unsolved in Cherokee.
