## Configuration

### SlurmFormSpawner

| Variable                          | Type    | Description                                     | Default |
| --------------------------------- | :------ | :---------------------------------------------- | ------- |
| `c.SlurmFormSpawner.disable_form`    | `CBool` | Disable the spawner input form, use only default values instead | `False` |
| `c.SlurmFormSpawner.error_template_path` | `Unicode` | Path to the Jinja2 template of the error page | `os.path.join(sys.prefix, 'share',  'slurmformspawner', 'templates', 'error.html')` |
| `c.SlurmFormSpawner.submit_template_path` | `Unicode` | Path to the Jinja2 template of the submit file | `os.path.join(sys.prefix, 'share', 'slurmformspawner', 'templates', 'submit.sh')` |
| `c.SlurmFormSpawner.ui_args` | `Dict` | Dictionary of dictionaries describing the UI options | refer to `ui_args` section |
| `c.SlurmFormSpawner.profile_args` | `Dict` | Dictionary of dictionaries describing profiles | refer to `profile_args` section |

#### `ui_args`

`ui_args` is a dictionary where the keys are labels that will be re-used in `SbatchForm.ui` and the values are dictionnaries describing how to launch the user interface.
Each option dictionary can have the following keys:
- `name` (required): string that will appear in the Spawner form
- `url`  (optional): url user is being redirected to after spawning the single-user server (refer to `JUPYTERHUB_DEFAULT_URL` documentation)
- `args` (optional): list of flags and options that will be appended to jupyter single-user command that should redirect to the UI.
- `modules` (optional): list of module names that needs to be loaded to make the user interface work

Here is an example of a dictionary that would configure Jupyter Notebook, a terminal and RStudio.
```
c.SlurmFormSpawner.ui_args = {
    'notebook' : {
        'name': 'Jupyter Notebook'
    },
    'terminal' : {
        'name': 'Terminal',
        'url': '/terminal/1'
    },
    'rstudio' : {
        'name': 'RStudio',
        'url': '/rstudio',
        'modules': ['rstudio-server']
    }
}
```

#### `profile_args`
`profile_args` is a dictionary where the keys are labels that are used in a JavaScript function to set values of the form according values specified in the `params` sub dictionary.

Each dictionary has the following keys:
- `name` (required): string that will appear in the Spawner form
- `params` (required): dictionary that can specify the value of each of the parameters in SbatchForm (see SbatchForm section).

Here is an example of how you could define profiles
```
c.SlurmFormSpawner.profile_args = {
    'shell' : {
        'name': 'Shell session',
        'params': {
            'nprocs': 1,
            'oversubscribe': True,
            'ui': 'terminal'
        }
    },
    'parallel_testing' : {
        'name': 'Parallel Testing',
        'params': {
            'nprocs': 8,
            'oversubscribe': False,
            'ui': 'lab',
            'runtime': 1,
        }
    }
}
```
