Hi,

First of all, is the book "Smalltalk by Example: the Developer's Guide" available from http://www.iam.unibe.ch/~ducasse/FreeBooks.html useful to learn Squeak. It look like this book is written with VisualWork, but I thought that it might be still useful in learning Smalltalk.

Second, can anyone suggest the right way to learn a Squeak? I have read a few online tutorials and one of the books (Squeak: Object-Oriented Design with Multmedia Application), but I do not feel comfortable with Squeak programming.

I have many years of OOP programming, mainly used C++/Java, so I do not need to learn the concept of OOP.

I will not be as sure as you. Every language have there own way off designing object especially Smalltalk who is type less.

But I let guru suggest you what to do.

Best regards, Mathew

Dear Squeakers

I am a complete novice Squeak looking for your advice.

Since you are already a pro, there probably is no right way which can be suggested.

I have read a few online tutorials and one of the books (Squeak: Object-Oriented Design with Multmedia Application), but I do not feel comfortable with Squeak programming.

Can anyone share the tips to become an efficient Squeak programmer?

Sure. So you are familiar with OO software development, let's see what you could do:

a) get used to Squeak (Smalltalk), there is no EMACS, no VI, no LD, etc. b) make the compiler your friend, he/she is the only one which creates new objects for you c) aggressively use do-it and print-it, just for everything new you see in Squeak d) there are so many features in Squeak - I cannot list them all, you must find it out (use google) e) one example is: select any selector in a method and do an alt-m (alt-W), etc

f) browse online tutorials and perhaps also more elementary material (like, The Language and its Implementation) for getting used to syntax and semantics. Work though every example that you see, write it, test it (SUnit is Squeak's test runner, it's my best friend, an old reliable)

g) invent new control structures, especially using compiled blocks

h) Squeak is a living being, your objects never die (except when you have no longer any reference to them). Your objects survive snapshots, they might destroy your work when revived, bite you and/or scream and shout (depending on what you tought them ;-)

i) look at what others have done, use the Squeak Map package loader

j) come back here with questions and critique, we are here to help

Hope that was not too much and that you feel comfortable with one or the other point from that list. As a starter I'd suggest you try and play with every object in the offering of the alt-o "thing" and often use alt-click (shows halos) and explore all the halo's offerings.

Thanks in advance.
