NAME¶
jocaml - The JoCaml interactive toplevelSYNOPSIS¶
jocaml [ -unsafe ] [ -I lib-dir ] [ object-files ] [ script-file ]DESCRIPTION¶
The jocaml(1) command is the toplevel system for JoCaml, that permits interactive use of the JoCaml system through a read-eval-print loop. In this mode, the system repeatedly reads Caml phrases from the input, then typechecks, compiles and evaluates them, then prints the inferred type and result value, if any. The system prints a # (sharp) prompt before reading each phrase.) are given, they are loaded silently before starting the toplevel.
OPTIONS¶
The following command-line options are recognized by jocaml(1).- -I directory
- Add the given directory to the list of directories searched
for source and compiled files. By default, the current directory is
searched first, then the standard library directory. Directories added
with -I are searched after the current directory, in the order in
which they were given on the command line, but before the standard library
directory.
- -unsafe
- Turn bound checking off on array and string accesses (the
v.(i) and s.[i] constructs). Programs compiled with -unsafe are
therefore slightly faster, but unsafe: anything can happen if the program
accesses an array or string outside of its bounds.
ENVIRONMENT VARIABLES¶
- LC_CTYPE
- If set to iso_8859_1, accented characters (from the ISO
Latin-1 character set) in string and character literals are printed as is;
otherwise, they are printed as decimal escape sequences.
- TERM
- When printing error messages, the toplevel system attempts
to underline visually the location of the error. It consults the TERM
variable to determines the type of output terminal and look up its
capabilities in the terminal database.
