Usage

To run the Narcissus shell, install the SpiderMonkey shell and either set the NJS_SHELL environment variable to the path to the js executable, or creating a symbolic link to js in the top-level Narcissus directory. Then run Narcissus with the njs script.

Usage: njs

Options:
  -h, --help            show this help message and exit
  -f FILE, --file=FILE  JS file to load
  -e JS_EXPS, --expression=JS_EXPS
                        JS expression to evaluate
  -i, --interactive     enable interactive shell
  -I, --interactive-meta
                        load Narcissus but run interactive SpiderMonkey shell
  -H, --harmony         enable ECMAScript Harmony mode
  -S, --ssa             enable parse-time SSA construction
  -P, --parse-only      stop after the parsing stage and output pretty-printed
                        source code
  -3, --ecma3-only      restrict source language to ECMA-262 Edition 3
  -p, --paren-free      use experimental paren-free syntax

Running the test suite

Before a pull request is accepted, you must run the SpiderMonkey test suite through njs and make sure that no new tests are failing.

To run the test suite, either set the NJS_TESTS environment variable to the path to the js/src/tests directory in the SpiderMonkey source tree, or create a symbolic link to js/src/tests in the top-level Narcissus directory. Then run the jstests script.

usage: jstests [-h | -a | <test> ...]
  -h      display this usage information and quit
  -a      run all but the slowest tests (those in xfail/narcissus-slow.txt)
  <test>  path to individual test (relative to test directory)

With no arguments, jstests runs all tests except those listed in
xfail/narcissus-failures.txt, which includes all the tests listed in
xfail/narcissus-slow.txt.
