Different languages supported by DrScheme offer different possible

customizations through the @onscreen{Show Details} button in the
|

dialog opened by @menuitem["Language" "Choose Language..."].
|

|

This chapter scribes some of the most common customizations that are
|
||||
available, though the actual set available depends on each language,
|
||||
which is in turn extensible through plug-ins.

@section[#:tag "output-syntax"]{Output Syntax}
|
||||
|
||||
@section-index["printing format"]
|
||||
|
||||
Many Scheme languages support a @onscreen{Output Syntax} choice that
|
||||
determines how evaluation results are printed in the
|
||||
@tech{interactions window}. This setting also applies to output
|
||||
generated by calling @scheme[print] explicitly.
|
||||
|
||||
The following table illustrates the difference between the different
|
||||
output styles:
|
||||
|
||||
@print-table[
|
||||
[(cons 1 2) (cons 1 2) `(1 . 2) (1 . 2)]
|
||||
[(list 1 2) (list 1 2) `(1 2) (1 2)]
|
||||
['(1 2) (list 1 2) `(1 2) (1 2)]
|
||||
[(list (void)) (list (void)) `(,(void)) (#,(@schemeresultfont "#<void>"))]
|
||||
[`(,(void)) (list (void)) `(,(void)) (#,(schemeresultfont "#<void>"))]
|
||||
[(vector 1 2 3) (vector 1 2 3) (vector 1 2 3) #(1 2 3)]
|
||||
[(box 1) (box 1) (box 1) #&1]
|
||||
[(lambda (x) x) (lambda (a1) ...) (lambda (a1) ...) #,(schemeresultfont "#<procedure>")]
|
||||
['sym 'sym 'sym sym]
|
||||
[(make-s 1 2) (make-s 1 2) (make-s 1 2) #(struct:s 1 2)]
|
||||
['() empty `() ()]
|
||||
[add1 add1 add1 #,(schemeresultfont "#<procedure:add1>")]
|
||||
[(delay 1) (delay ...) (delay ...) #,(schemeresultfont "#<promise>")]
|
||||
[(regexp "a") (regexp "a") (regexp "a") #rx"a"]
|
||||
]
|
||||
|
||||
The @as-index{@onscreen{Constructor} output} mode treats
|
||||
@scheme[cons], @scheme[vector], and similar primitives as value
|
||||
constructors, rather than functions. It also treats @scheme[list] as
|
||||
shorthand for multiple @scheme[cons]'s ending with the empty list.
|
||||
@onscreen{Constructor} output is especially valuable for beginning
|
||||
programmers, because output values look the same as input values.
|
||||
|
||||
The @as-index{@onscreen{Quasiquote} output} mode is like
|
||||
@onscreen{Constructor} output, but it uses @scheme[quasiquote]
|
||||
(abbreviated with @litchar{`}) to print lists, and it uses
|
||||
@scheme[unquote] (abbreviated with @litchar{,}) to escape back to
|
||||
@onscreen{Constructor} printing as needed. This mode provides the same
|
||||
benefit as @onscreen{Constructor} output, in that printed results are
|
||||
expressions, but it is more convenient for many kinds of data,
|
||||
especially data that represents expressions.
|
||||
|
||||
The @as-index{@onscreen{write} output} mode corresponds to traditional
|
||||
Scheme printing via the @scheme[write] procedure.
|
||||
|
||||
The @as-index{@onscreen{current-print} output} mode, when available,
|
||||
prints results using the value of the @scheme[current-print]
|
||||
parameter, which allows the programming running in DrScheme to control
|
||||
its own output format.

@section{Graphical Syntax}
|
||||
|
||||
In addition to normal textual program, DrScheme supports certain
|
||||
graphical elements as expressions within a program. Plug-in tools can
|
||||
extend the available graphical syntax, but this section describes some
|
||||
of the more commonly used elements.
|
||||
|
||||
@subsection{Images}
|
||||
|
||||
DrScheme's @menuitem["Insert" "Insert Image..."] menu item lets you
|
||||
select an image file from disk (in various formats such as GIF, PNG,
|
||||
and BMP), and the image is inserted at the current editing caret.
|
||||
|
||||
As an expression an image behaves like a number or string constant: it
|
||||
evaluates to itself. DrScheme's @tech{interactions window} knows how
|
||||
to draw image-value results or images displayed via @scheme[print].
|
||||
|
||||
A program can manipulate image values in various ways, such as using
|
||||
the @schememodname[htdp/image] library or as an
|
||||
@schememodname[image-snip%] value.
|
||||
|
||||
@subsection{XML Boxes and Scheme Boxes}
|
||||
|
||||
DrScheme has special support for XML concrete syntax. The
|
||||
@menuitem["Special" "Insert XML Box"] menu item inserts an embedded
|
||||
editor into your program. In that embedded editor, you type XML's
|
||||
concrete syntax. When a program containing an XML box is evaluated,
|
||||
the XML box is translated into an @deftech{x-expression} (or
|
||||
@deftech{xexpr}), which is an s-expression representation of an XML
|
||||
expression. Each xexpr is a list whose first element is a symbol
|
||||
naming the tag, second element is an association list representing
|
||||
attributes and remaining elements are the nested XML expressions.
|
||||
|
||||
XML boxes have two modes for handling whitespace. In one mode, all
|
||||
whitespace is left intact in the resulting xexpr. In the other mode,
|
||||
any tag that only contains nested XML expressions and whitespace has
|
||||
the whitespace removed. You can toggle between these modes by
|
||||
right-clicking or Control-clicking (Mac OS X) on the top portion of
|
||||
the XML box.
|
||||
|
||||
In addition to containing XML text, XML boxes can also
|
||||
contain Scheme boxes. Scheme boxes contain Scheme
|
||||
expressions. These expressions are evaluated and their
|
||||
contents are placed into the containing XML box's xexpr.
|
||||
There are two varieties of Scheme box: the standard Scheme
|
||||
box and the splicing Scheme box. The standard Scheme box
|
||||
inserts its value into the containing xexpr. The contents of
|
||||
the splice box must evaluate to a list and the elements of
|
||||
the list are ``flattened'' into the containing xexpr.
|
||||
Right-clicking or control-clicking (Mac OS X) on the top of a Scheme
|
||||
box opens a menu to toggle the box between a Scheme box and
|
||||
a Scheme splice box.

|

|

This section describes the different formats that DrScheme
|
||||
uses for printing results in the interactions window. Each
|
||||
of the different settings here also apply to the
|
||||
@scheme[print] primitive. That is, printing in the
|
||||
interactions window is identical to output produced by the
|
||||
@scheme[print] primitive.

{\drscheme}'s @defterm{constructor-style output} treats @scheme[cons],
|
||||
@scheme[vector], and similar primitives as value constructors, rather
|
||||
than functions. It also treats @scheme[list] as shorthand for multiple
|
||||
@scheme[cons]'s ending with the empty list. Constructor-style printing
|
||||
is valuable for beginning computer science students, because output
|
||||
values look the same as input values.
|
||||
|
||||
Results printed in DrScheme's interactions window using
|
||||
constructor-style printing look different than results printed in
|
||||
traditional Scheme implementations, which use @scheme[write] to print
|
||||
results. The table in Figure~\ref{fig:constructor-printing} shows the
|
||||
differences between values printed in constructor style and values
|
||||
printed with @scheme[write].

Constructor-style output is inconvenient for printing S-expression
|
||||
results that represent programs. For example, the value @scheme['(lambda
|
||||
(x) (lambda (y) (+ x y)))] prints as
|
||||
%
|
||||
\begin{center}
|
||||
@scheme[(list 'lambda (list 'x) (list 'lambda (list 'y) (list '+ 'x 'y)))]
|
||||
\end{center}
|
||||
%
|
||||
with constructor-style printing.
|
||||
|
||||
DrScheme's @defterm{quasiquote-style output} combines the
|
||||
input--output invariance of constructor-style printing with the
|
||||
S-expression readability of @scheme[write]. It uses @scheme[quasiquote] to
|
||||
print lists, and uses @scheme[unquote] to escape back to constructor
|
||||
style printing for non-lists and non-symbols.
|
||||
|
||||
With quasiquote-style printing, the above example prints as:
|
||||
%

||||

%
|

DrScheme has special support for XML concrete syntax. The
|
||||
@onscreen{Special} menu's @onscreen{Insert XML Box} menu inserts an
|
||||
embedded editor into your program. In that embedded editor,
|
||||
you type XML's concrete syntax. When a program containing an
|
||||
XML box is evaluated, the XML box is translated into an
|
||||
x-expression (or xexpr). Xexprs are s-expression
|
||||
representation for XML expressions. Each xexpr is a list
|
||||
whose first element is a symbol naming the tag, second
|
||||
element is an association list representing attributes and
|
||||
remaining elements are the nested XML expressions.
|
||||
|
||||
XML boxes have two modes for handling whitespace. In one
|
||||
mode, all whitespace is left intact in the resulting xexpr.
|
||||
In the other mode, any tag that only contains nested XML
|
||||
expressions and whitespace has the whitespace removed. You
|
||||
can toggle between these modes by right-clicking or
|
||||
control-clicking (Mac OS X) on the top portion of the XML box.
|
||||
|
||||
In addition to containing XML text, XML boxes can also
|
||||
contain Scheme boxes. Scheme boxes contain Scheme
|
||||
expressions. These expressions are evaluated and their
|
||||
contents are placed into the containing XML box's xexpr.
|
||||
There are two varieties of Scheme box: the standard Scheme
|
||||
box and the splicing Scheme box. The standard Scheme box
|
||||
inserts its value into the containing xexpr. The contents of
|
||||
the splice box must evaluate to a list and the elements of
|
||||
the list are ``flattened'' into the containing xexpr.
|
||||
Right-clicking or control-clicking (Mac OS X) on the top of a Scheme
|
||||
box opens a menu to toggle the box between a Scheme box and
|
||||
a Scheme splice box.

from the module to the importing module. Similarly, purple

lines are drawn for each for-syntax import. In the initial
|

module layout, modules to the left import modules to the
|

right, but since modules can be moved around
|
