Command-Line Tools
Racket provides, as part of its standard distribution, a number of command-line tools that can make racketeering more pleasant.
1. Compilation and Configuration: raco
The raco
short for “**Ra**cket **co**mmand”
program provides a
command-line interface to many additional tools for compiling Racket
programs and maintaining a Racket installation.
-
raco make
compiles Racket source to bytecode.For example, if you have a program
"take-over-world.rkt"
and you’d like to compile it to bytecode, along with all of its dependencies, so that it loads more quickly, then runraco make take-over-the-world.rkt
The bytecode file is written as
"take-over-the-world_rkt.zo"
in a"compiled"
subdirectory;".zo"
is the file suffix for a bytecode file. -
raco setup
manages a Racket installation, including manually installed packages.For example, if you create your own library collection called
"take-over"
, and you’d like to build all bytecode and documentation for the collection, then runraco setup take-over
-
raco pkg
manages packages that can be installed through the Racket package manager.For example, to see the list of installed packages run:
raco pkg show
To install a new package named
<package-name>
run:raco pkg install <package-name>
See [missing] for more details about package management.
For more information on raco
, see [missing].
2. Interactive evaluation
The Racket REPL provides everything you expect from a modern interactive
environment. For example, it provides an ,enter
command to have a REPL
that runs in the context of a given module, and an ,edit
command to
invoke your editor as specified by the `EDITOR` environment variable
on the file you entered. A ,drracket
command makes it easy to use your
favorite editor to write code, and still have DrRacket at hand to try
things out.
For more information, see [missing].
3. Shell completion
Shell auto-completion for bash
and zsh
is available in
"share/pkgs/shell-completion/racket-completion.bash"
and
"share/pkgs/shell-completion/racket-completion.zsh"
, respectively. To
enable it, just run the appropriate file from your .bashrc
or your
.zshrc
.
The "shell-completion"
collection is only available in the Racket Full
distribution. The completion scripts are also available
online.
