This section +presents here the kind of documents that can be created with Skribe. + +,(subsection :title "Simple computations" [ +In this section we present how to introduce a simple computation into a +document. For instance, the following sentence +,(disp [ +Document creation date: ,(date)]) +is generated with the following piece of code + +,(prgm :language skribe [ +\[Document creation date: \,(date)\] +]) + +Here, we use the Skribe function ,(code "date") to compute the date to +be inserted in the document. In general, any valid Scheme expression +is authorized inside a ,(code ",(...)") construct.,(footnote +[Skribe can be built either with Bigloo or STklos Scheme systems. The Scheme +expressions which are valid inside a ,(code ",(...)") depends of the Scheme system +used at Skribe construction.]). +Another example of +such a computation is given below. +,(prgm :language skribe [ +\[The value of \,(symbol "pi") is \,(* 4 (atan 1))\] +]) +When evaluated, this form produces the following output: +,(disp [ +The value of ,(symbol "pi") is ,(* 4 (atan 1)).]) +]) + +,(subsection :title "Text generation" [ When building a document, one +often need to generate some repetitive text.

So, it is easy to perform introspective tasks on the current +document. For instance the following code displays as an +enumeration the sections titles of the current chapter: + +,(prgm :language skribe :file "src/start5.skb") + +Without entering too much into the details here, the resolve function +is called at the end of the document processing. This function +searches the node representing the chapter to which belongs the +current node and from it finds all its sections.
