This section provides an overview of what scheme is, and why a developer might want to use it.
It should also mention any large subjects within scheme, and link out to the related topics. Since the Documentation for scheme is new, you may need to create initial versions of those related topics.
Installing CHICKEN Scheme
CHICKEN is a Scheme interpreter and compiler with its own extension module system called “eggs”. It is capable of compiling Scheme to native code by first compiling Scheme to C.
Debian or Ubuntu or other derived distros:
sudo apt-get install chicken-bin
Fedora / RHEL / CentOS:
sudo yum install chicken-bin
sudo pacman -S chicken
sudo emerge -av dev-scheme/chicken
OS X with Homebrew:
brew install chicken
doas pkg_add -vi chicken
Run the MSYS2 MinGW-w64 Shell
Install some prerequesites by running:
pacman -S mingw-w64-cross-toolchain base-devel mingw-w64-x86_64-gcc winpty wget
Download the latest release tarball by typing:
Extract the tarball by running
tar xvf chicken.tar.gz
Enter the extracted directory, for example by typing
make PLATFORM=mingw-msys install
If you have trouble running
csi, try instead running
To use the CHICKEN Scheme REPL, type
csi at the command line.
To compile a Scheme program using CHICKEN, run
csc program.scm, which will create an executable named
program in the current directory.
Chicken Scheme has a lot of modules that can be browsed in the egg index. Eggs are scheme modules that will be downloaded and then compiled by chicken-scheme. In some cases, it might be necessary to install external dependencies using your usual package manager.
You install the chosen eggs with this command:
sudo chicken-install [name of egg]
Making use of the REPL
You may wish to add
readline support to your REPL to make line editing in
csi behave more like you might expect.
To do this, run
sudo chicken-install readline, and then create a file named
~/.csirc with the following contents:
(use readline) (current-input-port (make-readline-port)) (install-history-file #f "/.csi.history")
The following are examples of how to install MIT/GNU Scheme:
sudo apt-get install mit-scheme
# Unpack the tar file tar xzf mit-scheme.tar.gz # move into the directory cd mit-scheme/src # configure the software ./configure
By default, the software will be installed in
/usr/local, in the subdirectories bin and lib. If you want it installed somewhere else, for example
/opt/mit-scheme, pass the
--prefix option to the configure script, as in
The configure script accepts all the normal arguments for such scripts, and additionally accepts some that are specific to MIT/GNU Scheme. To see all the possible arguments and their meanings, run the command
# build make compile-microcode # compile make install # may require super-user permissions (Depending on configuration)
MIT/GNU Scheme is distributed as a self-installing executable. Installation of the software is straightforward. Simply execute the downloaded file and answer the installer’s questions. The installer will allow you to choose the directory in which MIT/GNU Scheme is to be installed, and the name of the folder in which the shortcuts are to be placed.
