(chapter :title [Equation Formatting]
(p [Skribilo comes with an equation formatting package. This package
may be loaded by adding the following form at the top of your document:]
(disp (prog (source :language scheme
[(use-modules (skribilo package eq))])))
[It allows the inclusion of (complex) equations in your documents,
such as, for example, the following:]
(disp (eq :renderer (if (engine-format? "html") 'lout #f)
:ident "eq-disponibilite"
`(= (apply A D)
(sum :from (= i b) :to (* S b)
(* (script :sup (* S b) :sub i C)
(* (expt mu i)
(expt (- 1 mu)
(- (* S b) i))))))))
[This chapter will describe the syntactic facilities available to
describe equations, as well as the rendering options.])
(section :title [Syntax]
(p [To start with, let's have a look at a concrete example. ]
(example-produce
(example :legend "Example of a simple equation using the verbose syntax"
(prgm :file "src/eq1.skb"))
(disp (include "src/eq1.skb")))
[In this example, the ,(tt [eq:]) sub-markups are used pretty
much like any other kind of markup. However, the resulting syntax
is very verbose and hard to read.])
(p [Fortunately, the ,(tt [eq]) package allows for the use of a
much simple syntax. ]
(example-produce
(example :legend "Example of a simple equation"
(prgm :file "src/eq2.skb"))
(disp (include "src/eq2.skb")))
[Readers familiar with the Lisp family of programming languages
may have already recognized its ,(emph [prefix notation]). Note that,
unlike in the previous example, the equation itself if ,(emph [quoted]),
that is, preceded by the ,(tt [']) sign. Additionally, when referring
to a symbol (such as the Greek letter ,(symbol "phi")), you no longer
need to use the ,(tt [symbol]) markup (,(ref :text [see subsection]
:subsection "Symbols")).]))
