Re: [Pharo-project] PDF Rendering

last time I talked about it with olivier he told me that he can read pdf so he could do merging but may be I misremember.

Ok I was confused. I thought that you were mentioning generating pdf. Now for renderingâ¦ this is another story. Once we have athens may be this will be easier.

[Pharo-project] new version of the (old) versionner

by Alexandre Bergel

Hi! In the meantime we have a reliable solution to manage configuration, I have updated http://squeaksource.com/Versionner.html The two most significant changes are: - SmalltalkHub is now supported - Committing a project now produces a stable version (instead of a development) and the most recent baseline is marked as #development. In the meantime to have Versionner2 around, I worked a bit on Versionner to solve some pressing issues with Moose.

Re: [Pharo-project] OSProcess problem with Windows

by Alexander Svyazin

There is no such executable 'cd'. It is actually a command which is processed directly by shell interpreter (cmd.exe or powershell or something) and it works only in a shell session. You can execute 'cmd.exe /k cd "<something>"'. This command opens Windows command line interpreter and runs 'cd' afterwards but maybe it is not what you want.

Hi Alex, Thanks for fixing this! I know you are using it for Roassal. It is important to have you work in Pharo 2.0 :).
