_Janis is a framework creating specialised, simple workflow definitions that are then transpiled to   
Common Workflow Language or Workflow Definition Language._

## Introduction  

>| WARNING: this project is work-in-progress and is provided as-is without warranty of any kind. There may be breaking changes committed to this repository without notice. |
>|:--------------------------------------------------------------------------------------------------------------------------------------------------------------------------|


Janis gives you an API to build computational workflows and will generate
a workflow description in CWL and WDL. By using Janis, you get type-safety,
portability and reproducibility across all of your execution environments.


Janis requires a Python installation > 3.6, and can be installed through PIP 
([project page](https://pypi.org/project/janis-pipelines/)):  

```bash
# Install janis and the bioinformatics tools
pip3 install janis-pipelines 
```  

You can import Janis into your project with:  
```python  
import janis as j  
```

### Example  

Below we've constructed a simple example that takes a string input, calls the 
[echo](https://janis.readthedocs.io/en/latest/tools/unix/echo.html) tool and exposes the 
Echo tool's output as a workflow output.  

```python  
import janis as j
from janis.tools import Echo

w = j.WorkflowBuilder("workflowId")

w.input("inputIdentifier", j.String, default="Hello, World!")
w.step("stepIdentifier", Echo(inp=w.inputIdentifier))
w.output("outputIdentifier", source=w.stepIdentifier.out)

# Will print the CWL, input file and relevant tools to the console
w.translate("cwl", to_disk=False)  # or "wdl"
```

We can export a CWL representation to the console using `.translate("cwl")`. By including the 
`to_disk=True` parameter, we can write this workflow to disk at the current location.

## Support  

## v0.9.0 Backwards Compatability

**NOTE: Version 0.9.0 brings changes to output directories and camel case changes**

- Janis watch will be incompatible with previously run workflows
- Your configs might break, as previous versions of janis were not cautious about camel case.
- Your templates might not work with unrecognised keys (try changing them to camel case instead)
- Changes to BamBai indexes, format is now `.bam.bai`

See the [CHANGELOG](https://github.com/PMCC-BioinformaticsCore/janis/blob/master/CHANGELOG.md)
for more information.
