# task

## Usage

`prism create task` is used to create tasks in your project.

```
Usage: prism create task [-h] [--type TYPE] [-n N] [--name NAME] [--dir DIR] [--full-tb] [-l]

Create new tasks for your project

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

Subcommand Options:
  --type TYPE        Task type. One of `python`,`pyspark`. Default is `python`
  --decorated        If specified, the task will be a decorated function.
  -n, --number N     Number of tasks to create. Default is 1.
  --name NAME        Task name. If only a single task is requested, then the task will be named `<task_name>.py`. If multiple tasks are requested, then the tasks will be named `<task_name>_<number>.py`. Tasks
                     should have short, all-lowercase names. Underscores can be used in the module name if it improves readability.
  --dir DIR          Folder within the `modules` directory in which the new tasks should live. If not specified, then new tasks will be dumpted into `modules/`

General Options:
  --full-tb          Display the full traceback for errors in the project; default is False
  -l, --log-level    Log level, must be one of `info`, `warn`, `error`, or `debug`. Default is `info`
```

This command is fairly straightforward — it creates modules for the desired task type from a standard task template. It also names the file (and the corresponding Prism task class) according to the `name` argument.

## Example

Here's what the output will look like in Terminal (if there are no errors in the project):

```
$ prism create task --type python --name extract_data
--------------------------------------------------------------------------------
<HH:MM:SS> | INFO  | Running with prism v0.1.9...
<HH:MM:SS> | INFO  | Found project directory at /Users/my_first_project
 
<HH:MM:SS> | INFO  | RUNNING EVENT 'parsing prism_project.py'................................................ [RUN]
<HH:MM:SS> | INFO  | FINISHED EVENT 'parsing prism_project.py'............................................... [DONE in 0.03s]
 
<HH:MM:SS> | INFO  | Creating tasks...
 
<HH:MM:SS> | INFO  | Done!
--------------------------------------------------------------------------------
```

After running this command, your project directory will look like this:

```yaml
my_first_project/
  ├── data/
  ├── dev/
  │   └── dev.ipynb
  ├── output/
  ├── modules/
  │   ├── module01.py
  │   ├── module02.py
  │   └── extract_data.py
  ├── prism_project.py
  ├── profile.yml
  └── triggers.yml
```

Moreover, the `extract_data.py` task will look like:

```python
# modules/extract_data.py

import prism.task
import prism.target

class ExtractData(prism.task.PrismTask):
    
    def run(self, tasks, hooks):
        # TODO: implement
```
