|
|
|
|
This guide is intended for programmers who are new to Scheme, new to PLT
|
|
Scheme, or new to some part of PLT Scheme. It assumes
|
|
programming experience, so if you are new to programming, consider
|
|
instead reading @|HtDP|. If you want a brief introduction to PLT
|
|
Scheme, start with @|Quick|.
|
|
|
|
@seclink["to-scheme"]{Chapter 2} provides a brief introduction to
|
|
Scheme. From @seclink["datatypes"]{Chapter 3} on, this guide dives
|
|
into details---covering much of the PLT Scheme toolbox, but leaving
|
|
precise details to @|MzScheme| and other reference manuals.

@subsection{Simple Dispatch: @scheme[case]}
|
|
|
|
The @scheme[case] form dispatches to a clause by matching the result
|
|
of an expression to the values for the clause:
|
|
|
|
@specform[(case [(_datum ...+) expr ...+]
|
|
...)]

A @deftech{parameter} holds a kind of global option. For example,
|
|
there is a parameter that determines the default destination for
|
|
printed output.

@section[#:tag "mred"]{Graphical User Interfaces@aux-elem{ (GUIs)}}
|
|
|
|
@deftech{MrEd} is both a library and an executable. As a library,
|
|
@scheme[(lib "mred/mred.ss")] provides class, interface, and function
|
|
bindings for writing GUI programs. An an executable, @exec{mred}
|
|
substitutes for @exec{mzscheme} to run MrEd programs. (The
|
|
@exec{mzscheme} executable cannot run MrEd programs, because
|
|
@exec{mzscheme} does not include primitive GUI support, and because
|
|
some operating systems distinguish GUI applications from command-line
|
|
applications.)

@section[#:tag "tools"]{More Tools}
|
|
|
|
In the @seclink["intro"]{introduction}, we mentioned that PLT Scheme
|
|
includes more tools besides DrScheme and MzScheme:
|
|
|
|
@itemize{
|
|
|
|
@tool["MrEd"]{extends MzScheme with graphical user interface (GUI)
|
|
and drawing primitives}
|
|
|
|
@tool["Setup PLT"]{a command-line tool for installation tasks}
|
|
|
|
@tool["planet"]{a command-line tool for managing packages that are
|
|
normally downloaded automatically, on demand}
|
|
|
|
@tool["mzc"]{a command-line tool for miscellaneous tasks, such as
|
|
compiling Scheme source, compiling C-implemented extensions to the
|
|
run-time system, generating executables, and building distribution
|
|
packages}
|
|
|
|
}
