moterm_example_app is an example application that embeds Moterm, uses it to provide a prompt, and allows it to be connected to other applications (which should implement the mojo.terminal.TerminalClient interface).
On Linux, run it in the usual way, e.g.:
$ mojo/devtools/common/mojo_run --enable-multiprocess "mojo:window_manager mojo:moterm_example_app"
You'll probably need to click on the window to give it keyboard focus. You may also want to resize the window (especially horizontally) to make it bigger.
At the :) prompt, you may enter the URL for any application implementing the mojo.terminal.TerminalClient interface. E.g.:
:) mojo:dart_netcat
At this point, the terminal's input/output is transferred to the specified application. In this case, it just outputs a help message and closes the terminal, returning you to the :) prompt. You may also try:
:) mojo:dart_netcat?localhost&port=80
In this case, mojo:dart_netcat will make a TCP connection to the specified host/port. Assuming you have a web server running on your machine, you may try entering:
GET /
(It‘s probably a bug in mojo:dart_netcat that it doesn’t close the terminal “file”. You can press Control-D to return to the :) prompt. The unhandled Dart exception after you press Control-D is definitely a bug.)
Another example you may try is:
:) file:///path/to/src/examples/js/repl.js
At its > prompt, you can enter JavaScript expressions. E.g.:
> function add(x, y) { return x + y; }
undefined
> add("hello ", 123)
"hello 123"
