I own a copy of "The School of Niklaus Wirth" :) I really appreciate the pragmatism of Wirth's designs and his quest for simplicity.

I wrote a simple self-hosting compiler to showcase Niklaus Wirth's approach to writing compilers: https://github.com/lboasso/oberonc Single pass compilers have their advantages.

It makes sense now, Thanks!

I should have linked the other paper by Ierusalimschy, "Revisiting Coroutines". wahern linked it in his reply. They are both good reads to better understand coroutines.

A good start could be "Coroutines in Lua" [1]. It explains well the terminology and makes comparisons between designs in different languages. [1] http://www.inf.puc-rio.br/~roberto/docs/corosblp.pdf

Thanks, my hope is that the Oberon language will not be forgotten. The Oberon0 language, described in the compiler book, is just a toy to illustrate basic compiler techniques. The full Oberon language is a simple but powerful language, that

I agree, Niklaus Wirth's compiler book is a good introduction to the topic. To showcase Wirth's approach, I wrote a self hosted Oberon compiler for the JVM: https://github.com/lboasso/oberonc The compiler can

The DEFINITION is an extension of my compiler. It sets the compiler in a different mode, accepting only declarations in the source file. You approach would work, but I prefer a new keyword showing the intent of the source file. DEFINITION

The 2013 edition of that book (updated with the latest source code) is available at Wirth's website: http://people.inf.ethz.ch/wirth/ProjectOberon/index.html

Yes a custom foreign function interface is needed. In my compiler I did the bare minimum to bootstrap the compiler. Currently you can create a definition module that makes the bridge between the Java and Oberon worlds. For example the Obero

If you just want to play with the Oberon-07 language (the one used to implement the whole system), there are several compilers available for different platforms. You can find a list here: http://oberon07.com/compilers.xhtml

The Oberon language was instrumental for the creation of the Oberon operating system. Writh makes this clear in several articles. For example http://people.inf.ethz.ch/wirth/ProjectOberon/PO.System.pdf in the &quo

Wirth wrote many articles about the design of his programming languages, a nice starting point for Oberon/Modula-2 is: http://people.inf.ethz.ch/wirth/Articles/Modula-Oberon-June....

Thanks to Robert Griesemer (Phd student of Prof. Wirth), the Go programming language includes some design lessons taken from the Oberon language

For those interested, you can find the latest Oberon system by Prof. Wirth here: http://people.inf.ethz.ch/wirth/ProjectOberon/ You can run Project Oberon with this emulator (pre-built binaries available): https:

I think Wirth's compiler book is more approachable for a beginner. Once you are done with that book you can also read "Project Oberon" from the same author. This way you can understand the implementation of a full graphical O

I would recommend "Compiler Construction" by Niklaus Wirth. This small book (< 200 pages) will teach you the basics and show you how to build a single-pass compiler for a subset of Oberon (a Pascal successor). The book is freel

Niklaus Wirth is an amazing engineer/computer scientist, unfortunately he is often unknown by new generations (especially later achievements, like Oberon). I was inspired by his work and never ending quest for simple and effective solu

Gosu is more than 10 years old. For some historical background/design decisions please have a look at this article: http://www.drdobbs.com/open-source/language-of-the-month-gos...

You can have a look at the pom.xml[1] of SparkGS [2](a micro web framework using Gosu). It uses maven, so a 'mvn package' should generate the jars for you. [1] https://github.com/sparkgs/sparkgs/blob&#x2F

So by default the type inferred is ArrayList, if you want a different type you just specify it. ex. var strings = { "red", "green", "blue" } //ArrayList var strings2 : LinkedList<String> = { &

Exactly if you want to return just an expression you can avoid them, otherwise if you use statements in the body of the lambda you need curly braces.

Java 8 lambdas are not real lambdas, they capture only effectively final local variables. In Gosu you can modify the value of a captured variable.
