NAME

       emrun - emscripten tool to compile as an HTML page

DESCRIPTION

       usage: emrun [emrun_options] filename.html -- [html_cmdline_options]

              where  emrun_options specifies command line options for emrun itself, whereas html_cmdline_options
              specifies startup arguments to the program.

       If you are seeing "unrecognized arguments" when trying to pass arguments to your page,  remember  to  add
       `--` between arguments to emrun itself and arguments to your page.

   positional arguments:
              serve cmdlineparams

   options:
       -h, --help
              show this help message and exit

       --kill-start
              If true, any previously running instances of the target browser are killed before starting.

       --kill-exit
              If  true,  the  spawned  browser process is forcibly killed when it calls exit(). Note: Using this
              option may require explicitly passing the option --browser=/path/to/browser, to avoid emrun  being
              detached from the browser process it spawns.

       --no-server
              If specified, a HTTP web server is not launched to host the page to run.

       --no-browser
              If specified, emrun will not launch a web browser to run the page.

       --no-emrun-detect
              If  specified,  skips printing the warning message if html page is detected to not have been built
              with --emrun linker flag.

       --serve-after-close
              If true, serves the web page even after the application quits by user closing the web page.

       --serve-after-exit
              If true, serves the web page even after the application quits by a call to exit().

       --serve-root SERVE_ROOT
              If set, specifies the root path that the emrun web server serves. If not specified, the  directory
              where the target .html page lives in is served.

       --verbose
              Enable verbose logging from emrun internal operation.

       --hostname HOSTNAME
              Specifies the hostname the server runs in.

       --port PORT
              Specifies the port the server runs in.

       --log-stdout LOG_STDOUT
              Specifies a log filename where the browser process stdout data will be appended to.

       --log-stderr LOG_STDERR
              Specifies a log filename where the browser process stderr data will be appended to.

       --silence-timeout SILENCE_TIMEOUT
              If  no  activity  is received in this many seconds, the browser process is assumed to be hung, and
              the web server is shut down and the target browser killed.  Disabled by default.

       --timeout TIMEOUT
              If the browser process does not quit or the page exit() in  this  many  seconds,  the  browser  is
              assumed  to  be  hung,  and the web server is shut down and the target browser killed. Disabled by
              default.

       --timeout-returncode TIMEOUT_RETURNCODE
              Sets the exit code that emrun reports back to caller in the  case  that  a  page  timeout  occurs.
              Default: 99999.

       --list-browsers
              Prints out all detected browser that emrun is able to use with the --browser command and exits.

       --browser BROWSER
              Specifies the browser executable to run the web page in.

       --browser-args BROWSER_ARGS
              Specifies the arguments to the browser executable.

       --android
              Launches  the page in a browser of an Android device connected to an USB on the local system. (via
              adb)

       --android-tunnel
              Expose the port directly to the Android device and connect to it as localhost, establishing  cross
              origin  isolation.  Implies  --android. A reverse socket connection is created by adb reverse, and
              remains after emrun terminates (it can be removed by adb reverse --remove).

       --system-info
              Prints information about the current system at startup.

       --browser-info
              Prints information about the target browser to launch at startup.

       --json If specified, --system-info and --browser-info are outputted in JSON format.

       --safe-firefox-profile
              If true, the browser is launched into a new clean Firefox profile that is suitable for  unattended
              automated runs. (If target browser != Firefox, this parameter is ignored)

       --private-browsing
              If specified, opens browser in private/incognito mode.

       --dump-out-directory DUMP_OUT_DIRECTORY
              If specified, overrides the directory for dump files using emrun_file_dump method.
