@title{Getting Started with Racket}
|
|
|
|
To get started with Racket,
|
|
@link["http://www.racket-lang.org/download/"]{download it} from the web page and
|
|
install it. If you are a beginner or would like to use a graphical environment
|
|
to run programs, run the @exec{DrRacket} executable. Otherwise, the @exec{racket}
|
|
executable will run a command-line Read-Eval-Print-Loop
|
|
(@tech[#:doc '(lib "scribblings/guide/guide.scrbl")]{REPL}).
|
|
|
|
On Windows, you can start DrRacket from the @onscreen{Racket} entry in the
|
|
Start menu. In Windows Vista or newer, you can just type @exec{DrRacket}. You can
|
|
also run it from its folder, which you can find in @onscreen{Program Files} →
|
|
@onscreen{Racket} → @onscreen{DrRacket}.
|
|
|
|
On Mac OS X, double click on the @onscreen{DrRacket} icon. It is probably in a
|
|
@onscreen{Racket} folder that you dragged into your
|
|
@onscreen{Applications} folder. If you want to use command-line tools, instead,
|
|
Racket executables are in the @filepath{bin} directory of the @onscreen{Racket}
|
|
folder (and if you want to set your @envvar{PATH} environment variable, you'll
|
|
need to do that manually).
|
|
|
|
On Unix (including Linux), the @exec{drracket} executable can be run directly from the
|
|
command-line if it is in your path, which is probably the case if you chose a
|
|
Unix-style distribution when installing. Otherwise, navigate to the directory
|
|
where the Racket distribution is installed, and the @exec{drracket} executable will be
|
|
in the @filepath{bin} subdirectory.
|
|
|
|
If you are new to programming or if you have the patience to work
|
|
through a textbook:
|
|
|
|
@itemize[
|
|
|
|
@item{@italic{@link["http://htdp.org/"]{How to Design Programs}}
|
|
is the best place to start. Whenever the book says ``Scheme,''
|
|
you can read it as ``Racket.''}
|
|
|
|
@item{@other-manual['(lib "web-server/scribblings/tutorial/continue.scrbl")]
|
|
introduces you to modules and building web applications.}
|
|
|
|
@item{@other-manual['(lib "scribblings/guide/guide.scrbl")] describes
|
|
the rest of the Racket language, which is much bigger than
|
|
the learning-oriented languages of the textbook. Since you
|
|
learned functional programming from the textbook, you'll be
|
|
able to skim chapters 1 and 2 of the Guide.}
|
|
|
|
]
|
|
|
|
|
|
If you're already a programmer and you're in more of a hurry:
|
|
|
|
@itemize[
|
|
|
|
@item{@other-manual['(lib "scribblings/quick/quick.scrbl")] gives you
|
|
a taste of Racket.}
|
|
|
|
@item{@other-manual['(lib "scribblings/more/more.scrbl")] dives much
|
|
deeper and much faster. If it's too much, just skip to the
|
|
Guide.}
|
|
|
|
@item{@other-manual['(lib "scribblings/guide/guide.scrbl")] starts
|
|
with a tutorial on Racket basics, and then it describes the rest
|
|
of the Racket language.}
|
|
|
|

|
|
|
|
Of course, you should feel free to mix and match the above two tracks,
|
|
since there is information in each that is not in the other.
