The Cuis Book

A book about Cuis Smalltalk. A community effort to bring documentation to people new to Smalltalk and even computer programming. The book comes in three parts.

The book includes examples and exercises. The solutions of the exercises are in the annexes. We encourage writers to provides both examples then exercises with solutions in annexes.

Notes to the writers

The book is written with the GNU Texinfo software. It is the documentation package of the GNU project. It is a well-maintained and documented project. Documentation written with Texinfo can be converted to info, PDF, HTML, docbook, and text formats. We provide a makeBook.sh script to output HTML and PDF.

Documentation

The Texinfo format is mainly pure text. Tagging is done with @ command, for example to @strong{strong} or @url{http://cuis-smalltalk.org}

To learn more about the Texinfo format:

• Ref. card letter size or Ref. card A4 size
• GNU Texinfo manual

TODO

• So far, the current index mixes both concepts and methods. It will be nicer to have two separate indexes: one for the concepts and another one for the methods.

Writing documentation

General recommendations

Indentation. Indent with 0, 3, 6, etc spaces when writing code. Do not use tab unless the text editor converts it to spaces.

Index. Index when important concepts are explained. We write index entries in lowercase! Insert an index just after a section title, and just before a paragraph. The command to use is @cindex for the conceptual index: @cindex tools @subentry workspace

Regarding indexing messages, here is the rule:

• When the message name is meaningful, index with messsage name itself with the appropriate tag. For example @cindex number @subentry @method{isPrime}

• When the message name is not meaningful enough or too long, index with a meaningful term. For example, @cindex number @subentry as words for the message printStringWords; or @cindex number @subentry base for the message printStringBase:

Macros and commands to use

We defined a few macros too. Of course, standard Texinfo commands are used. You should look at the written documentation to see when and how to use them.

@cuis{}. To name Cuis-Smalltalk everywhere it is necessary

@vm{}. For Virtual Machine

@class{Object}. To cite a class

@method{collect:}. To cite a method

@msg{collect:}. to cite a message (will render as #collect:)

@smalltalk{5 factorial}. To cite a portion of Smalltalk code in a flow of text

@kbd{Ctrl-A}. To name a keyboard shortcut

@label{resize...}. To name a menu entry or a button label

@dfn{Workspace}. To emphasize a new term when it is first defined. Use only once.

@clicksequence{} To describe click sequence, for example:

...@clicksequence{Background click @click{} Open... @click{} Workspace}...

@smalltalkExample{smalltalk code}. To display in its own block environment an example of Smalltalk code. Use this when writing an example that doesn't need to be added to list of examples nor referenced from elsewhere.

@smalltalkExemple{@{1 . 2 . 3 @} collect: [:x | x @@ 3]}

@smalltalkExampleCaption{caption,uniqueLabel,smalltalk code}. To display in its own block environment an example of Smalltalk code. A caption is added below the example. The uniqueLabel is a reference to be used elsewhere with @ref{uniqueLabel}. The example will be added to the list of examples in the annexes.

@exercise{caption,uniqueLabel,text}. To display in its own block environment an exercise. The exercises are compiled in the annexes, and the resolved exercise must be added to the E-Exercises annex too.

@figure{caption,filename,width}. Add a centered image with a caption with the given width in cm. The filename (without path) must be located in the img folder, alongside the source .texinfo file that inserted this command.

@button{filename}. To insert a button (0.5 cm width}

@icon{filename}. To insert an icon (1 cm width)

@cuisNote{aNote}. Display a highlighted note in a frame

Tips when using a macro

TO GET...	...WRITE
@	@@
{ (in a macro)	@{
} (in a macro)	@}
, (in a macro with multiple arguments)	@comma{}

Compile the documentation

To compile the documentation, you need to install the Texinfo package and PDFLatex. Texinfo is shipped with all GNU/Linux distributions. There are packages for other systems.

To compile, invoke the build script, for example: makeBook en pdf
