Thanks Mariano, this is deeply needed in order to distribute knowledge and to lower the entry barrier to the VM.

Great!! Just subscribed to your blog. It sounds wonderful and will be the best preparation in order to be able to read Eliots blog :) Norbert Am 31.03.2011 um 22:28 schrieb Mariano Martinez Peck: > Hi folks.

[OT] Blog sequence "Journey through the VM"

by Mariano Martinez Peck

Hi folks. I will start a sequence of VM related posts called âJourney through the VMâ, similar to what Igor did in Deep Smalltalk School<http://www.inria.fr/centre-de-recherche-inria/lille-nord-europe/agenda/smal…>. My main focus is that a regular Smalltalker, without any knowledge in VM stuff can understand the basis of it (ObjectMemory, Interpreter, etc). In addition, I expect the reader can download, change, compile, run, and debug (and why not fixing?) the VM. Later on in the journey, I would also like to talk about what the compiler does, what bytecodes are, how to read them, how they are mapped to the VM, etc. I will also show some hooks or tricks that the VM provides and that are not always known. Moreover, I will explain what a primitive is, how they are executed by the VM, how you can write your own primitives, etc. FFI and writing your own plugin are also in my plans. It is important to notice that all these posts are thought for VM newbies. I would appreciate if there can be some VM hackers paying attention that I don't say stupid things. http://marianopeck.wordpress.com/ Cheers

Re: [Pharo-users] More elegant way?

by AxiNat

Hi Friederich, here's two simple optimizations: #(#nul #soh #stx #etx #eot #enq #ack #bel #bs #tab #lf) withIndexDo: [:each :index | self class compile: each asString , ' ^ asciiField at: ', index asString.]. Array withAll: #(1 2 3) is equivalent to #(1 2 3), and if you're not going to use the array again, you don't even need to assign it to a variable :) Instead of manually using an index, it is more elegant to use withIndexDo: Cheers, Bernat Romagosa.

More elegant way?

by Friedrich Dominicus

I've spend the better time of the afternoon with trying metaprogramming with Smalltalk I finally have come up with: asciiNames := Array withAll: #(#nul #soh #stx #etx #eot #enq #ack #bel #bs #tab #lf). i := 1. asciiNames do: [ :each | self class compile: each asString , ' ^ asciiField at: ', i asString. i := i + 1 ]. which at least does what I want given names to ASCI Codes. Now I have to admit I dislike this stuff with putting a string togehter and run compile: on this string. I'm sure there is a more elegant way. Would you mind to lend me a hand? Yes and because I think I will need much more code generation in the near future. Does you have nice Tutorial, Book whatever to do such kind of jobs in Smalltalk I've quite a lot of books about Smalltalk but none has this as theme... So it's really a bit hard to get into it....
