+'Squeak by Example
+
+Squeak by Example is a book, intended for both students and developers, that will guide you through the Smalltalk language and the Squeak environment by means of a series of examples and exercises. The book helps you getting started with an initial tour of the environment before introducing the details of the language, the standard library, the tools, and the Morphic framework.
+
+About this version of the book
+
+Squeak by Example is a classical book intended for PDF/print format in the first place. Nevertheless, we made some efforts to make it available right in Squeak. For this, we wrote our own LaTeX parser that uses Sandblocks'' Tree-sitter integration and a LaTeX grammar for tree-sitter to convert over 10,000 SLOC of text into Squeak objects (don''t try this at home!!). You can read the result in this help structure or search it using the search bar at the top. Note that this parser is meant to be an approximation only and we didn''t get every space right to save our own sanity. Nevertheless, if you''ve got any questions or feedback, we''re there at our GitHub repo: https://github.com/hpi-swa-lab/SqueakByExample-english
+
+Enjoy and carpe Squeak!!!

+	"This is all very hacked. Some of the most awkward hacks and issues include:
+	* Insufficient grammar: It produces a lot of syntax errors. This has not been fully investigated but some known trigger include special characters in verbatim code like \ct{$a inspect}, \ct|{| (ah, why can't LaTeX be context-free). Maybe it would be enough to manually extend the grammar, maybe we would need a C plugin for tree-sitter.
+	* Handling of syntax errors: Currently requires a LOT of hacks because some commands appear without all of their arguments, some commands appear as plain text, sometimes braces and square brackets appear as plain text nodes, etc. so we need to consume tokens from sibling nodes through the parseStack mechanism in a redundant manner.
+	* Token consumption: parseStack is a fancy piece of stuff but we seem to be using generators in an unusual way (consume before produce), leading to an underflow/overflow of tokens that we have not fully understood and that prevented us from extracting a common generator logic. Further, there is a loop on the call stack (literally) while these generators are active which crashes the VM when you dare to not catch a single exception from within their block ... happy debugging!
+	* Eager/lazy evaluation of tokens is not yet waterproof, just works good enough for this book. There are places such as LaTeX-inside-lstlisting
+	* We could introduce better support for handling optional arguments of commands and environments.
+	* Improve and refactoring handling of spaces at the beginning/end of lines, after commands, and multiple new lines in a row.
+	* \makeatletter...\makeatother
+	* conditional environment begins/ends
+	* many more hacks i cannot count
+	
+	And of course there are many features not (yet) imlpemented, including tables, floatings, index/citations, labels for references, real footnotes, ..."

 About this version of the book
 
-Squeak by Example is a classical book intended for PDF/print format in the first place. Nevertheless, we made some efforts to make it available right in Squeak. For this, we wrote our own LaTeX parser that uses Sandblocks'' Tree-sitter integration and a LaTeX grammar for tree-sitter to convert over 10,000 SLOC of text into Squeak objects (don''t try this at home!!). You can read the result in this help structure or search it using the search bar at the top. Note that this parser is meant to be an approximation only and we didn''t get every space right to save our own sanity. Nevertheless, if you''ve got any questions or feedback, we''re there at our GitHub repo: https://github.com/hpi-swa-lab/SqueakByExample-english

+'How to use this book
+
+You can read this book from beginning to end, from end to beginning, or browse through random sections as your interests take you. Either way, here are some tips on how to get the most out of reading this book right in Squeak:
+
+Interactive contents. Since Squeak is a super-duper-interactive system, you can also interact directly with the contents of this book. For example, you can select any mentioned message and press Cmd+m to browse its implementors, just like anywhere else in the image. Analogously, Cmd+b is available to browse a class definition, Cmd+p to print an expression, Cmd+D to debug it, and all your other favorite shortcuts.
+
+Smart search. Did you notice the search bar at the top of this window? You can search the entire book with it!!!!1 More importantly, if you also have installed the SemanticText package, this will even perform a smart search powered by OpenAI. So, instead of "exception handling", you could just search for "catch errors". Note that this is an experimental feature and watch out for artificial stupidity and hallucinations.
+
+Fallback to PDF. While we managed to parse most of the book in a satisfactory quality, we just could not get some things right (yet). (Imagine parsing a context-sensitive language with a context-free grammar?) So, if you encounter an unreadable artifact, send your thanks to Donald Knuth and yellow-click on the relevant section in the tree to open it in a PDF in the great darkness outside of Squeak.!

+You can read this book from beginning to end, from end to beginning, look up things in the index, or browse through random sections as your interests take you. Either way, here are some tips on how to get the most out of reading this book right in Squeak:
 
 Interactive contents. Since Squeak is a super-duper-interactive system, you can also interact directly with the contents of this book. For example, you can select any mentioned message and press Cmd+m to browse its implementors, just like anywhere else in the image. Analogously, Cmd+b is available to browse a class definition, Cmd+p to print an expression, Cmd+D to debug it, and all your other favorite shortcuts.
 
 Smart search. Did you notice the search bar at the top of this window? You can search the entire book with it!!!!1 More importantly, if you also have installed the SemanticText package, this will even perform a smart search powered by OpenAI. So, instead of "exception handling", you could just search for "catch errors". Note that this is an experimental feature and watch out for artificial stupidity and hallucinations.
 
-Fallback to PDF. While we managed to parse most of the book in a satisfactory quality, we just could not get some things right (yet). (Imagine parsing a context-sensitive language with a context-free grammar?) So, if you encounter an unreadable artifact, send your thanks to Donald Knuth and yellow-click on the relevant section in the tree to open it in a PDF in the great darkness outside of Squeak.!
