Re: [Pharo-users] Package browser?

by Jon Hancock

The latest PDF download is dated 2009-10-28. I would be very happy to purchase a book that was updated. Either through and autobuild or one of the writers could once a month publish a manual build. I spent in total a day trying top get a Laytex environ working on my Mac. I couldn't get the book to build and it left me tons of stuff installed without a clear way to remove. I do understand you are trying to balance having the book open and still make some cash. Maybe you should jside more with making some cash. The barrier to building the boook on your own is high. Just go ahead and strike a deal with one of the book vendors that will manage this for you. Pragmatic Programmers has a great beta books system. Having more recent copies in more hands my push the book dev faster too. thanks, Jon On Thu, Feb 24, 2011 at 4:40 AM, Norbert Hartl <norbert(a)hartl.name> wrote: > > On 23.02.2011, at 15:22, Rob Vens wrote: > >> I am attempting to do the Pharo by Example book, but a package browser (which is used in the examples) is not in the 1.1.1 or 1.2 image. >> Should I still use categories?

As you could see on the website a second edition of the book is in the make. I would advize you to start with the current book. It gets you going in using smalltalk and pharo. After that the second edition will be available. Quite some things will have changed then but nothing fundamental regarding smalltalk.

Just drag and drop the .changes in another image, and browse them. Or open the .changes with your favorite text editor and copy paste ;) Check in the archives, there were several answers: http://forum.world.st/Pharo-f1294836.html > 2) Is there anyone who wants a copy of the crash.dmp report?

Like Miguel said you should use the image from the website. As you could see on the website a second edition of the book is in the make. I would advize you to start with the current book. It gets you going in using smalltalk and pharo. After that the second edition will be available. Quite some things will have changed then but nothing fundamental regarding smalltalk.

IMHO the only fix is to use the image from the website. There is a reason for this image. If you are a newbie than everything that does not work like it is written in the book is distracting. Giving advize to load a browser that is neither in the book nor is it used by a lot of people is definitely not a good idea. Norbert

I'm not exactly a seasoned Pharo user, but I think you can file in code from your .changes file by opening it (as you open any other file from within Pharo) from a fresh/clean image. --Aidan
