_SLIB_ Initialization File
--------------------------
The "init.ss" file in the _slibinit_ collection is an SLIB
initialization file (tested with version 3a2).
To use SLIB in MzScheme:
(load (build-path (collection-path "slibinit") "init.ss"))
or
(require (lib "load.ss" "slibinit")) ; loads "init.ss"
That's enough if the SCHEME_LIBRARY_PATH environment variable is
defined, or if SLIB is installed as an "slib" collection (i.e., in an
"slib" directory in the same location as the "mzlib" directory).
SLIB is not integrated with MzScheme's module system. Instead, SLIB
works in the top-level environment, and it provides its own "feature"
system using the function `require'. Unfortunately, that function name
conflicts with MzScheme's own `require' form. In an attempt to work
around this collision, "init.ss" re-defines `require' as syntax:
require [not in app position] -> slib:require
> (require '<something>) -> (slib:require '<something>)
(require <any> ...) -> (mz:require <any> ...)
where `slib:require' is bound to SLIB's require function, and
`mz:require' is bound to MzScheme's `require' syntax.
SLIB's `implementation-vicinity' points to the PLT installation
directory. If that directory is not writable by SLIB users, then
initialize the installation with
(require (lib "load.ss" "slibinit"))
(require 'new-catalog) ; which is an SLIB `require'
The initialization file contains one system-dependent setting:
`most-positive-fixnum' is bound to a value that is precisely correct
for 32-bit architectures. The precise value for a 64-bit architecture
is in the file, but commented out. The only problem with using the
32-bit value for a 64-bit architecture is a decrease in performance.
No other changes should be necessary. Send patches to
bugs@plt-scheme.org.
