.SH NAME

compile-scheme \- Compiling Scheme programs to executables
|
|
.SH SYNOPSIS
|
|
\fBcompile-scheme\fR { [\fB-A\fR \fIpath\fR] [\fB-I\fR \fIpath\fR] [\fB-o\fR \fIpath\fR] [\fB-t\fR \fItarget\fR] \fIinput-file\fR{\fI.scm\fR | \fI.sps\fR} | \fIlong-option\fR }
|
|
.SH DESCRIPTION
|
|
.P
|
|
\fBcompile-scheme\fR is a tool to compile R6RS and R7RS Scheme programs.
|
|
It supports most of SRFI-138 but also adds more features.
|
|
.P
|
|
The program \fIinput-file\fR is compiled into an executable file.
|
|
The resulting executable file is written to file specified by the \fB-o\fR \fIpath\fR (if present) or to the file named same as \fIinput-file\fR but without the .scm or .sps suffix.
|
|
On Windows either .bat or .exe is appended to the output name.
|
|
.SS SUPPORT LIST
|
|
.P
|
|
Some implementations support both compiling and interpreting, in that
|
|
case only the compiler functionality is used and the implementation is marked
|
|
as compiler.

.SH OPTIONS
|
|
.P
|
|
\fB\-A\fR \fIpath\fR
|
|
Append path to the list of directories that are searched in order to locate imported libraries.
|
|
.P
|
|
\fB\-I\fR \fIpath\fR
|
|
Prepend directory to the list of directories that are searched in order to locate imported libraries.
|
|
.P
|
|
\fB-o\fR \fIoutput-file\fR
|
|
Use the \fIoutput-file\fR file, instead of the default deducted from input-file, for the executable file produced.
|
|
.P
|
|
Multiple instances of the -A, and -I options can be specified.
|
|
.P
|
|
\fB\-t\fR { \fIunix\fR | \fIwindows\fR | \fIphp\fR }
|
|
Set the compilation target.
|
|
This is not needed if you are compiling for the target OS you are running.
|
|
Cross compilation is only supported in following cases:
|
|
.IP
|
|
From \fIunix\fR host to \fIphp\fR target when chosen implementation is interpreter.
|
|
.IP
|
|
From \fIunix\fR host to \fIwindows\fR target when chosen implementation is interpreter.
|
|
.P
|
|
.B \-\-list-r6rs
|
|
List supported R6RS implementations.
|
|
.P
|
|
.B \-\-list-r7rs
|
|
List supported R7RS implementations.
|
|
.P
|
|
.B \-\-list-all
|
|
List all supported implementations.
|
|
.P
|

Either of these environment variables \fBmust\fR be set.
|

Set either to the \fBname\fR of the implementation as specified in the support list.
|

\fBThis differs from SRFI-138\fR as the SRFI excepts a path.

Differences from SRFI-138
|
|
.IP
|
|
No support for -D flag.
|
|
.IP
|
|
Not all implementations support adding to beginning or end of load path so -I and -A might work the same
|
|
.IP
|
|
Only supports one input-file.
