6 ocaml - The Objective Caml interactive toplevel
7
11 ocaml [ -unsafe ] [ -I lib-dir ] [ object-files ] [ script-file ]
12
14 The ocaml(1) command is the toplevel system for Objective Caml, that
15 permits interactive use of the Objective Caml system through a read-
16 eval-print loop. In this mode, the system repeatedly reads Caml phrases
17 from the input, then typechecks, compile and evaluate them, then prints
18 the inferred type and result value, if any. The system prints a #
19 (sharp) prompt before reading each phrase.
20 A toplevel phrase can span several lines. It is terminated by ;; (a
22 double-semicolon). The syntax of toplevel phrases is as follows.
23 The toplevel system is started by the command ocaml(1). Phrases are
25 read on standard input, results are printed on standard output, errors
26 on standard error. End-of-file on standard input terminates ocaml(1).
27 If one or more object-files (ending in .cmo or .cma
29 ) are given, they are loaded silently before starting the toplevel.
30 If a script-file is given, phrases are read silently from the file,
32 errors printed on standard error. ocaml(1) exits after the execution
33 of the last phrase.
34
37 The following command-line options are recognized by ocaml(1).
38 -I directory
41 Add the given directory to the list of directories searched for
42 source and compiled files. By default, the current directory is
43 searched first, then the standard library directory. Directories
44 added with -I are searched after the current directory, in the
45 order in which they were given on the command line, but before
46 the standard library directory.
47 -unsafe
50 Turn bound checking off on array and string accesses (the v.(i)
51 and s.[i] constructs). Programs compiled with -unsafe are there‐
52 fore slightly faster, but unsafe: anything can happen if the
53 program accesses an array or string outside of its bounds.
54
57 LC_CTYPE
58 If set to iso_8859_1, accented characters (from the ISO Latin-1
59 character set) in string and character literals are printed as
60 is; otherwise, they are printed as decimal escape sequences.
61 TERM When printing error messages, the toplevel system attempts to
64 underline visually the location of the error. It consults the
65 TERM variable to determines the type of output terminal and look
66 up its capabilities in the terminal database.
