Developer's Guide, Potential Wrong Command Line Example

[awareness481]

Towards the end of the guide, the following example is used to serve the compiled files over http: $ emrun --no_browser --port 8080

However, this didn't work for me and typing emrun in the terminal gives me the following text:

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.

Type emrun --help for a detailed list of available options.

To create the localhost I needed to run:

$ emrun --no_browser --port 8080 hello.html

The filename is missing from the command-line example in the Developer's guide, which is needed to create the localhost page from the compiled files.

I'm not sure if guide had this snippet at the time of your issue, but you might have missed the . at the end, so the command was actually: emrun --no_browser --port 8080 .
