csi - Man Page

The CHICKEN Scheme interpreter

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.
