4.1  Command line format

csi {FILENAME|OPTION}

where FILENAME specifies a file with Scheme source-code. If the extension of the source file is .scm, it may be omitted. The runtime options described in 3.1 are also available for the interpreter. If the environment variable CSI_OPTIONS is set to a list of options, then these options are additionally passed to every direct or indirect invocation of csi. Please note that runtime options (like -:...) can not be passed using this method. The options recognized by the interpreter are:

-
Ignore everything on the command-line following this marker. Runtime options (``-:...'') are still recognized.

-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.

-batch
Quit the interpreter after processing all command line options.

-eval EXPRESSIONS
Evaluate EXPRESSIONS.

-feature SYMBOL
Registers SYMBOL to be a valid feature identifier for cond-expand.

-help
Write a summary of the available command line options to standard output and exit.

-hygienic
Load syntax-case macro package and enable high-level macros in interpreted code. This option registers the hygienic-macros feature identifier.

-include-path PATHNAME
Specifies an alternative 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 ``;''. The environment variable CHICKEN_HOME is also considered as a search path.

-keyword-style STYLE
Enables alternative keyword syntax, where STYLE may be either prefix (as in Common Lisp) or suffix (as in DSSSL). Any other value is ignored.

-no-feature SYMBOL
Unregisters feature identifier SYMBOL.

-no-init
Do not load initialization-file. If this option is not given and the file /.csirc exists, then it is loaded before the read-eval-print loop commences.

-no-warnings
Disables any warnings that might be issued by the reader or evaluated code.

-quiet
Do not print a startup message.

-r5rs
Equivalent to -hygienic -strict.

-script PATHNAME
This is equivalent to -batch -quiet -no-init PATHNAME. Arguments following PATHNAME are available by using command-line-arguments and are not processed as interpreter options.

-script-meta PATHNAME
This is similar to the -script option, but the file specified by PATHNAME is opened, the first line is treated as containing additional command line options and (after processing all the options) the code from the given file is loaded.

-srfi-7
Process any source files as SRFI-7 configuration language (see: the SRFI-7 document 2).

-strict
Disable non-standard macros. Implies -strict-letrec and -strict-reader.

-strict-srfi-0
Disable non-standard macros except cond-expand. Implies -strict-letrec and -strict-reader.

-strict-reader
Disables non-standard read syntax. Implies -case-insensitive.

-strict-letrec
Enable fully R5RS compliant letrec. This generates slightly less efficient code but preserves standard semantics.

-version
Write the banner with version information to standard output and exit.

-visit FILENAME
Reads the source file FILENAME and performs macro-expansions. This makes macros defined in that file available without actually loading the code.
