6 gosh - a Scheme script interpreter

10 [-E expr ] [-f flag ] [--] [ script argument ... ]
11
13 Gosh is a stand-alone Scheme interpreter built on top of the Gauche
14 Scheme script engine.
15 When script is given, gosh loads the script, evaluating Scheme code in
17 it. Then, if the script defines a procedure named main, gosh calls it
18 with a single argument which is a list of the script name and subse‐
19 quent arguments. When main returns an integer value, gosh exits with
20 it as an exit code. If main returns non-integer value, or an error is
21 signaled during evaluation, gosh exits with exit code 70 (EX_SOFTWARE).
22 See SRFI-22 (http://srfi.schemers.org/srfi-22/srfi-22.html) for
23 details. If there's no main procedure defined in the script, gosh
24 exits with code 0 after loading the script file.
25 If no script file is given, gosh goes into an interactive mode. By
27 default, gosh prompts the user to enter a Scheme expression, read and
28 evaluates it, then prints the result, until EOF is read. If the stan‐
29 dard input is not a terminal, however, gosh doesn't print a prompt; it
30 allows a user to use gosh as a filter program. This behavior can be
31 controlled by -i or -b option; see below.
32
35 Command line options are processed before loading the script file or
36 entering the interactive mode.
37 The options -I, -A, -u, -l, -L, -e and -E are processed in the order of
39 appearance. For example, adding a load path by -I option affects the
40 -l options after it, but not the ones before it.
41 -V Prints gosh version and exits.
44 -b Batch mode. Doesn't print prompt even the standard input is a
46 terminal. Supersedes -i.
47 -i Interactive mode. Forces to print prompt, even the standard input
49 is not a terminal.
50 -q Prevents reading the default initialization file.
52 -Ipath
54 Adds path in front of the load path list.
55 -Apath
57 Appends path to the tail of the load path list.
58 -umodule
60 Loads and imports module, as if "(use module )" is specified in
61 the code.
62 -lfile
64 Loads a Scheme file file.
65 -Lfile
67 Like -l, but doesn't complain if file doesn't exist.
68 -eexpr
70 Evaluates a Scheme expression expr.
71 -Eexpr
73 Same as -e, except that the expr is read as if it is surrounded by
74 parenthesis.
75 -ptype
77 Turns on the profiler. Currently type can only be 'time'.
78 -fflag
80 Sets various flags.
81 case-fold uses case-insensitive reader (as in R5RS)
82 load-verbose report while loading files
83 no-inline don't inline primitive procedures and constants
84 (combined no-inline-globals, no-inline-locals,
85 and
86 no-inline-constants.)
87 no-inline-globals don't inline global procedures.
88 no-inline-locals don't inline local procedures.
89 no-inline-constants don't inline constants.
90 no-post-inline-pass don't run post-inline optimization pass.
91 -Ffeature
93 Makes feature available in cond-expand forms.
94 -- Specifies that there are no more options. If there are more argu‐
96 ments after this, they are taken as script file name and its argu‐
97 ments.
98
101 GAUCHE_LOAD_PATH
102 A colon separated list of the load paths.
103 The paths are appended before the system default load paths.
104 GAUCHE_DYNLOAD_PATH
106 A colon separated list of the load paths for dynamically loaded
107 objects. The paths are appended before the system default load
108 paths.
