NAME

       js_of_ocaml - Js_of_ocaml compiler

SYNOPSIS

       js_of_ocaml [OPTION]... [JS_FILES]... PROGRAM

DESCRIPTION

       Js_of_ocaml is a compiler from OCaml bytecode to Javascript. It makes it possible to run pure OCaml
       programs in JavaScript environments like web browsers and Node.js.

OPTIONS (TOPLEVEL)

       --export=VAL
           File containing the list of unit to export in a toplevel.

       --nocmis, --no-cmis
           Do not include cmis when compiling toplevel.

       --toplevel
           Compile a toplevel.

OPTIONS (FILESYSTEM)

       --extern-fs
           Configure pseudo-filesystem to allow registering files from outside. (default)

       --file=FILE
           Register [FILE] to the pseudo filesystem.

       -I DIR
           Add [DIR] to the list of include directories.

       --no-extern-fs
           Configure pseudo-filesystem to NOT allow registering files from outside.

       --ofs=FILE
           Output the filesystem to [FILE].

ARGUMENTS

       JS_FILES
           Link  JavaScript files [JS_FILES]. One can refer to path relative to Findlib packages with the syntax
           '+pkg_name/file.js'

       PROGRAM (required)
           Compile the bytecode program [PROGRAM]. Use '-' to read from the standard input instead.

OPTIONS

       --custom-header=VAL
           Provide a custom header for the generated JavaScript file, useful for making the script an executable
           file with #!/usr/bin/env node

       --debug=SECTION
           enable debug [SECTION].

       --debuginfo, --debug-info
           Output debug information.

       --disable=OPT
           Disable optimization [OPT].

       --dynlink
           Enable dynlink.

       --enable=OPT
           Enable optimization [OPT].

       --help[=FMT] (default=auto)
           Show this help in format FMT. The value FMT must be one of `auto', `pager', `groff' or `plain'.  With
           `auto', the format is `pager` or `plain' whenever the TERM env var is `dumb' or undefined.

       --keep-unit-names
           Keep unit name

       --linkall
           Link all primitives.

       --no-sourcemap, --no-source-map
           Don't generate source map. All other source map related flags will be be ignored.

       --noinline, --no-inline
           Disable inlining.

       --noruntime, --no-runtime
           Do not include the standard runtime.

       -o FILE
           Set output file name to [FILE].

       --opt=NUM
           Set optimization profile : [NUM].

       --pretty
           Pretty print the output.

       -q, --quiet
           suppress non-error messages.

       --runtime-only
           Generate a JavaScript file containing/exporting the runtime only.

       --set=PARAM=VALUE
           Set compiler options.

       --setenv=PARAM=VALUE
           Set environment variable statically.

       --source-map-inline
           Inline sourcemap in the generated JavaScript.

       --source-map-no-source
           Do not inline sources in source map.

       --source-map-root=VAL
           root dir for source map.

       --sourcemap, --source-map
           Generate source map.

       --version
           Show version information.

       --wrap-with-fun=VAL
           Wrap the generated JavaScript code inside a function that needs to be applied with the global object.
