Is there a way to move the pharo window around, resize it and generally control it ?

This will let you open a Smalltalk shell window directly within your Squeak/Pharo boot image, so that you have access to the operating system with actually opening any windows or terminal sessions outside of your image. http://www.squeaksource.com/CommandShell http://www.squeaksource.com/OSProcess Dave

Awesome. I must have been sleeping when I did my first test. Next question - if I might: is there a quick way to read the header and get the records read into dictionaries? Regards, Markus

Re: [Pharo-users] Multiline fields and NeoCSVReader

Hi Markus, NeoCSVReader is not like most CSV readers ;-) (NeoCSVReader on: '"COL1";"COL2";"COL3";"DESCRIPTION" 1;"A string";13;"This is a long description spanning multiple lines, which is a challenge for most csv readers!" 2;"Another string";42;""' readStream) separator: $; ; upToEnd. => #( #('COL1' 'COL2' 'COL3' 'DESCRIPTION') #('1' 'A string' '13' 'This is a long description spanning multiple lines, which is a challenge for most csv readers!') #('2' 'Another string' '42' nil)) HTH, Sven PS: There are many features, like #readHeader and #skipHeader, and a whole, optional, mechanism to directly create your own objects and convert fields to specific types (like parsing numbers or dates).

Multiline fields and NeoCSVReader

by Markus Fritsche

Hi, I am having a csv file looking like "COL1";"COL2";"COL3";"DESCRIPTION" 1;"A string";13;"This is a long description spanning multiple lines, which is a challenge for most csv readers!" 2;"Another string";42;"" (CRLF line endings) Is there a combination of settings to NeoCSVReader that will allow to read such a file? Kind regards, Markus

Class categories are system categories :). Since Pharo 3.0, they are replaced with RPackage. They are still around at the moment as a backup system, but almost everything in the image should now work through RPackage. The difference between the two is that while system categories are awkward strings, RPackages are explicit objects. To learn more, you can inspect for example: RPackageOrganizer default packages Cheers, Doru On Sun, Sep 21, 2014 at 5:33 PM, Trygve Reenskaug <trygver(a)ifi.uio.no> wrote: > Doru, > "*Now pay attention class categories will not exist in the future.*" > I already know about system categories (categories of classes) and method > categories within a class. > I understood you to mean system categories. > What are class categories and why will they be removed? > --Trygve > > > > On 21.09.2014 15:36, Tudor Girba wrote: > > What do you mean? > > Doru > > On Sun, Sep 21, 2014 at 2:42 PM, Trygve Reenskaug <trygver(a)ifi.uio.no> > wrote: > >> >> On 20.09.2014 14:51, stepharo wrote: >> >> This is cool I blog about it. >> Now pay attention class categories will not exist in the future. >> >> Stef >> >> Any ref to this development? >> > > > > -- > www.tudorgirba.com > > "Every thing has its own flow" > > > -- www.tudorgirba.com "Every thing has its own flow"
