Pass command line arguments to Bokeh server application

Question

I have a Bokeh server application. I would like to pass it custom options on the command line: ``` bokeh serve /path/to/script.py --my-option foo ``` Is this possible? Will Bokeh pass these options through somehow?

Accepted Answer

Yes, use the `--args` command line option described in the User's Guide. Everything you put after the `--args` option will just appear in `sys.argv` for the app code, just as you would expect with any normal python script.

Running this app:

```
import sys
print(sys.argv)
```

With this invocation:

```
bokeh serve foo.py --args -x 1 bar --baz
```

Then opening a session will result in this being printed:

```
['foo.py', '-x', '1', 'bar', '--baz']
```
