CHICKEN(1)CHICKEN(1)NAMEchicken - A Scheme-to-C compiler
SYNOPSISchicken pathname [ option ... ]
DESCRIPTION
Chicken is a compiler for the programming language Scheme supporting
most of the features as described in the Revised^5 Report on the Algo‐
rithmic Language Scheme
OPTIONS-analyze-only
Stop compilation after first analysis pass.
-benchmark-mode Equivalent to -optimize-level 3 -fixnum-arith‐
metic -disable-interrupts -lambda-lift -block -no-lambda-info
-block Enable block-compilation. When this option is specified, the
compiler assumes that global variables are not modified outside
this compilation-unit.
-case-insensitive
Enables the reader to read symbols case-insensitive. The default
is to read case-sensitive (in violation of R5RS). This option
registers the case-insensitive feature identifier.
-check-imports
Search for references to undefined global variables.
-check-syntax
Aborts compilation process after macro-expansion and syntax
checks.
-database-size number
Specifies the initial size of the analysis-database. Should only
be used if extremely large files are to be compiled.
-debug modes
Enables one or more debugging modes. See the User's Manual for
more information.
-debug-level level
Selects amount of debug-information. level should be an inte‐
ger.
0 -no-trace -no-lambda-info
1 -no-trace
2 nothing.
-disable-c-syntax-checks
Disable basic syntax checking of embedded C code fragments.
-disable-compiler-macros
Disable expansion of compiler macros.
-disable-interrupts
Equivalent to -prelude "(declare (interrupts-disabled))"
-disable-stack-overflow-checks
Disables detection of stack-overflows.
-disable-warning class
Disables specific class of warnings, may be given multiple
times.
-dynamic
This option should be used when compiling files intended to be
loaded dynamically into a running Scheme program.
-epilogue filename
Includes the file named filename at the end of the compiled
source file. The include-path is not searched. This option may
be given multiple times.
-emit-debug-info
Emit additional information for each lambda expression (cur‐
rently the argument-list, after alpha-conversion/renaming).
-emit-exports filename
Write exported toplevel variables to file filename
-emit-external-prototypes-first
Emit prototypes for callbacks defined with define-external
before any other foreign declarations. This is sometimes useful,
when C/C++ code embedded into the a Scheme program has to access
the callbacks. By default the prototypes are emitted after for‐
eign declarations.
-explicit-use
Disables automatic use of the units library and eval instead of
an application unit.
-extend filename
Loads a Scheme file before compilation commences. This feature
can be used to extend the compiler.
-extension
Mostly equivalent to -prelude ´°fine-extension NAME´ where NAME
is the basename of the currently compiled file. Note that if you
want to compile a file as a normal (dynamically loadable) exten‐
sion library, you should also pass the -shared option.
-feature symbol
Registers symbol to be a valid feature identifier for
cond-expand
-fixnum-arithmetic
Equivalent to -prelude "(declare (fixnum))"
-heap-size number
Sets the static heap-size of the generated executable to number
bytes. The parameter may be followed by a M or K suffix which
stand for mega- and kilobytes, respectively. The default heap-
size is 16 megabytes.
-heap-initial-size number
Sets the size that the heap of the compiled application should
have at startup time.
-heap-growth percentage
Sets the heap-growth rate for the compiled program at compile
time.
-heap-shrinkage percentage
Sets the heap-shrinkage rate for the compiled program at compile
time.
-help Print a summary of available options and the format of the com‐
mand-line parameters and exit the compiler.
-import pathname
Read exports from linked or loaded libraries from given file.
Implies -check-imports
-include-path pathname
Specifies an additional search path for files included via the
include special form. This option may be given multiple times.
If the environment variable CHICKEN_INCLUDE_PATH is set, it
should contain a list of alternative include pathnames separated
by ;
-inline
Enables procedure inlining.
-inline-limitthreshold
Sets the maximum size of potentially inlinable procedures.
-keep-shadowed-macros
Do not remove macro definitions with the same name as assigned
toplevel variables (the default is to remove the macro defini‐
tion).
-keyword-stylestyle
Enables alternative keyword syntax, where style may be either
prefix (as in Common Lisp), suffix (as in DSSSL) or none Any
other value is ignored. The default is exttt{suffix}.
-lambda-lift
Enable the optimization known as lambda-lifting.
-no-trace
Disable generation of tracing information. If a compiled exe‐
cutable should halt due to a runtime error, then a file contain‐
ing a stack-trace will be written to the current directory under
the name STACKTRACE With this option given, the generated code
is slightly faster.
-no-warnings
Disable generation of compiler warnings.
-nursery number
-stack-size number
Sets the size of the first heap-generation of the generated exe‐
cutable to number bytes. The parameter may be followed by a M or
K suffix. The default stack-size depends on the target platform.
-optimize-leaf-routines
Enable leaf routine optimization.
-optimize-level level
Enables certain sets of optimization options. level should be
an integer. Each optimization level corresponds to a certain set
of optimization option as shown in the following list:
0 nothing
1 -optimize-leaf-routines
2 -optimize-leaf-routines -usual-integrations
3 -optimize-leaf-routines -usual-integrations -unsafe
-output-file filename
Specifies the pathname of the generated C file. Default is FILE‐
NAME.c
-postlude expressions
Add expressions after all other toplevel expressions in the com‐
piled file. This option may be given multiple times. Processing
of this option takes place after processing of -epilogue
-prelude expressions
Add expressions before all other toplevel expressions in the
compiled file. This option may be given multiple times. Pro‐
cessing of this option takes place before processing of -pro‐
logue
-profile
-accumulate-profile Instruments the source code to count proce‐
dure calls and execution times. After the program terminates
(either via an explicit exit or implicitly), profiling statis‐
tics are written to a file named PROFILE.<PID> where <PID> is
the process ID of the program being profiled. Each line of the
generated file contains a list with the procedure name, the num‐
ber of calls and the time spent executing it. Use the
chicken-profile program to display the profiling information in
a more user-friendly form.
-profile-name filename
Specifies the name of the generated profile information file.
Only useful in combination with the -profile or -accumulate-pro‐
file options.
-prologue filename
Includes the file named filename at the start of the compiled
source file. The include-path is not searched. This option may
be given multiple times.
-quiet Disables output of compile information.
-release
Print release number and exit.
-require-extension name
Loads the syntax-extension name before the source program is
processed. This is identical to adding require-extension NAME at
the start of the compiled program.
-run-time-macros
Makes low-level macros (defined with define-macro also available
at run-time. By default low-level macros are not available at
run-time. Note that highlevel-macros ("syntax-case")
defined in compiled code are never available at run-time.
-to-stdout
Write compiled code to standard output instead of creating a .c
file.
-unit name
Compile this file as a library unit.
-unsafe
Disable runtime safety checks.
-unsafe-libraries
Marks the generated file for being linked with the unsafe run‐
time system. This should be used when generating shared object
files that are to be loaded dynamically. If the marker is
present, any attempt to load code compiled with this option will
signal an error.
-uses name
Use definitions in the given library unit.
-usual-integrations
Specifies that standard procedures and certain internal proce‐
dures are never redefined, and can be inlined. This is equiva‐
lent to declaring (usual-integrations)
-verbose
Prints progress information to standard output during compila‐
tion.
-version
Prints the version and some copyright information and exit the
compiler.
ENVIRONMENT VARIABLES
CHICKEN_PREFIX
Is used as a prefix directory for support files, include-files
and libraries.
CHICKEN_INCLUDE_PATH
Contains one or more pathnames where the compiler should addi‐
tionally look for include-files, separated by ; characters.
CHICKEN_OPTIONS
Holds a string of default compiler options that should apply to
every invocation of chickenDOCUMENTATION
