This chapter describes the forms composing Skribilo texts that
use the Skribe syntax (see Section 2.1). In XML/HTML jargon these forms are called markups. In LaTeX they are called macros. In Skribilo
these forms are called functions. In this manual, we will say
that we call a function when a function is used in a form.
The values used in a function call are named the actual
parameters of the function or parameters in short. When
calling a function with parameters we say that we are passing
arguments to the function.
In this document function names are typeset in boldface. We call
keyword argument a named argument, i.e., an argument whose
name, starting with a colon (:), must be specified when the
function is called. Other arguments are called plain
arguments or arguments for short. An optional
argument is represented by a list, starting with the character "[" and ending with the character "]", whose first
element is a keyword argument and the optional second (
not specified) element is the default value used if the optional
argument value is not provided on a function call. Arguments that are
not optional are said mandatory. If a plain argument is
preceded by a . character, this argument may be used to
accumulate several values. There are two ways to pass actual arguments
to a function:
for keyword arguments: the value of the parameter
must be preceeded by the name of the argument.
for plain arguments: a value is provided.
Example: Let us consider the function section
defined as follows:
The argument :title
is a mandatory keyword argument.
The keyword arguments :number
optional. The plain argument
is preceeded with a
character so it may receive several values. All the following
calls are legal section
The remainder of this chapter describes ``standard'' markups or
functions that are commonly used in documents. By ``standard'', we mean
two things: first, you will quickly notice that they look familiar if
you have ever written, say, HTML or LaTeX documents; second, they are
standard because these markups are always available by default to
Skribilo documents, unlike those bundled in separate packages such as
pie charts, slides, etc. In fact, these markups are also bundled in a
package, called base, but this package is always available to
