Alex Shinn's matcher library for Chez Scheme

Primary LanguageScheme

Description

This is a library for Chez Scheme providing the portable hygienic pattern matcher by Alex Shinn http://synthcode.com/.

Note: the catch all symbol ‘_’ has been replaced by ‘:_’ because R6RS doesn’t allow its use as an auxiliary keyword in syntax-case.

Build

To build the libraries run “make”. By default it looks for a Chez Scheme binary called “chez-scheme”. If the name of your binary is different, you can specify it as follows (for all targets):

make CHEZ=my-chez-scheme-bin

To test the build run

make test

Running the tests requires SRFI-78.

Install

By default “make install” will install the libraries under the prefix “/usr/local”. You can specify a different installation prefix directory as follows:

make install PREFIX=/my-prefix/path

This will install all compiled libraries (*.so files) to $PREFIX/lib/csvX.Y-site, where X.Y is Chez’s version. If in addition you want to install the source files, use the ‘install-src’ target. They are installed in the same directory as the .so files.

Use

Make sure that Chez Scheme can find the libraries by specifying their location on the command line (with the appropriate flag), or by setting the environment variable CHEZSCHEMELIBDIRS.
