GOSH(1) Gauche Commands GOSH(1) NAME gosh - a Scheme script interpreter SYNOPSIS gosh [-bhiqV] [-I path ] [-A path ] [-u module ] [-l file ] [-L file ] [-e expr ] [-E expr ] [-m module ] [-f flag ] [-F feature ] [-p type ] [-r standard ] [--] [ script argument ... ] DESCRIPTION Gosh is a stand-alone Scheme interpreter built on top of the Gauche Scheme script engine. When script is given, gosh loads the script, evaluating Scheme code in it. Then, if the script defines a procedure named main, gosh calls it with a single argument which is a list of the script name and subse- quent arguments. When main returns an integer value, gosh exits with it as an exit code. If main returns non-integer value, or an error is signaled during evaluation, gosh exits with exit code 70 (EX_SOFTWARE). See SRFI-22 (http://srfi.schemers.org/srfi-22/srfi-22.html) for de- tails. If there's no main procedure defined in the script, gosh exits with code 0 after loading the script file. If no script file is given, gosh goes into an interactive mode. By de- fault, gosh prompts the user to enter a Scheme expression, read and evaluates it, then prints the result, until EOF is read. If the stan- dard input is not a terminal, however, gosh doesn't print a prompt; it allows a user to use gosh as a filter program. This behavior can be controlled by -i or -b option; see below. OPTIONS Command line options are processed before loading the script file or entering the interactive mode. The options -I, -A, -u, -l, -L, -e and -E are processed in the order of appearance. For example, adding a load path by -I option affects the -l options after it, but not the ones before it. -V Prints gosh version and exits. -b Batch mode. Doesn't print prompt even the standard input is a terminal. Supersedes -i. -h Print help message to stdout and exit with 0. -i Interactive mode. Forces to print prompt, even the standard input is not a terminal. -q Prevents reading the default initialization file. -Ipath Adds path in front of the load path list. -Apath Appends path to the tail of the load path list. -umodule Loads and imports module, as if "(use module )" is specified in the code. -lfile Loads a Scheme file file. -Lfile Like -l, but doesn't complain if file doesn't exist. -eexpr Evaluates a Scheme expression expr. -Eexpr Same as -e, except that the expr is read as if it is surrounded by parenthesis. -mmodule When the script file is given, this option specifies the name of the module in which the "main" procedure is defined. The default is "user". -ptype Turns on the profiler. Type can be either 'time' or 'load'. -rstandard Starts gosh with the default environment defined in RnRS, where n is determined by standard. Currently, only 7 is the valid value of standard. -vversion If version is not the running Gauche's version, but the specified verision is installed in the system, execute taht version's gosh instead. This is useful when you want to invoke a specific ver- sion of Gauche. The version must be 0.9.6 or later. -fflag Sets various flags. case-fold use case-insensitive reader (as in R5RS) load-verbose report while loading files include-verbose report while including files no-inline don't inline primitive procedures and constants (combined no-inline-globals, no-inline-locals, no-inline-constants and no-inline-setters.) no-inline-globals don't inline global procedures. no-inline-locals don't inline local procedures. no-inline-constants don't inline constants. no-inline-setters don't inline setters. no-post-inline-pass don't run post-inline optimization pass. no-lambda-lifting-pass don't run lambda lifting optimization pass. no-post-inline-pass don't run post-inline optimization pass. no-source-info don't retain source information. read-edit enable input editing mode, if terminal supports it. no-read-edit disable input editing mode. safe-string-cursors performs extra validation for use of string cursors. warn-legacy-syntax print warning when legacy Gauche syntax is encountered. test assume being run in the build tree; tries to load files from the current build instead of installation directories. Useful to test the build without installation. -Ffeature Makes feature available in cond-expand forms. -- Specifies that there are no more options. If there are more argu- ments after this, they are taken as script file name and its argu- ments. ENVIRONMENT GAUCHE_LOAD_PATH A colon separated list of the load paths. The paths are appended before the system default load paths. GAUCHE_DYNLOAD_PATH A colon separated list of the load paths for dynamically loaded objects. The paths are appended before the system default load paths.
