NAME

     csi — The CHICKEN Scheme interpreter

SYNOPSIS

     csi [OPTION ...] [FILENAME ...]

DESCRIPTION

     csi is an interpreter for the programming language Scheme supporting most of the features as
     described in the Revised^5 Report on the Algorithmic Language Scheme.  csi is implemented as
     a program compiled with the CHICKEN compiler.

     FILENAME is a Scheme source file name with optional extension.  OPTION may be  one of the
     following:

     -h, -help
             Display usage and exit.

     -version
             Display version and exit.

     -release
             Print release number and exit.

     -i, -case-insensitive
             Enable case-insensitive reading.

     -e EXPRESSION, -eval EXPRESSION
             Evaluate the given expression.

     -p EXPRESSION, -print EXPRESSION
             Evaluate and print the result(s) of the given expression.

     -P EXPRESSION, -pretty-print EXPRESSION
             Evaluate and print result(s) prettily.

     -D SYMBOL, -feature SYMBOL
             Register feature identifier.

     -no-feature SYMBOL
             Disable built-in feature identifier.

     -q, -quiet
             Do not print banner.

     -n, -no-init
             Do not load initialization file.  ‘.csirc’

     -b, -batch
             Terminate after command-line processing.

     -w, -no-warnings
             Disable all warnings.

     -K STYLE, -keyword-style STYLE
             Enable alternative keyword-syntax (prefix, suffix or none)

     -no-parentheses-synonyms
             Disable list delimiter synonyms.

     -no-symbol-escape
             Disables support for escaped symbols.

     -r5rs-syntax
             Disable the CHICKEN extensions to R5RS syntax.

     -s PATHNAME, -script PATHNAME
             Use interpreter for shell scripts.

     -ss PATHNAME
             Run a script with a ‘main’ procedure

     -sx PATHNAME
             Same as -s, but print each expression as it is evaluated.

     -setup-mode
             Prefer the current directory when locating extensions.

     -R NAME, -require-extension NAME
             Import extension before executing code.

     -I PATHNAME, -include-path PATHNAME
             Add PATHNAME to the include path.

     --      Ignore all following options.

ENVIRONMENT

     The following environment variables change the behaviour of csi:

     CSI_OPTIONS           When set to a string of command-line options, then the options are
                           passed implicitly to every direct or indirect invocation of csi. Note
                           that runtime options of the form ‘-:⟨OPTIONS⟩’ cannot be passed using
                           this method.

     CHICKEN_INCLUDE_PATH  Contains one or more pathnames where the interpreter should also look
                           for include files, separated by ‘;’ characters.

FILES

     $XDG_CONFIG_HOME/chicken/csirc
           Scheme file loaded on startup. ( $XDG_CONFIG_HOME defaults to $HOME/.config )

     $HOME/.csirc
           Scheme file loaded on startup if the previous one doesn’t exists.

EXIT STATUS

     The csi utility exits 0 on success, and >0 if an error occurs.
