cloud-slang-content

CloudSlang is a YAML based language for writing human-readable workflows for the Cloud Slang Orchestration Engine (Score). This repository includes CloudSlang flows and operations.

Getting started:

Pre-Requisite: Java JRE >= 7

Download the CloudSlang CLI file named cslang-cli-with-content:
- Stable release
- Latest snapshot
Extract it.
Go to the folder cslang/bin/
Run the executable :

For Windows : cslang.bat
For Linux : bash cslang

Run a simple example print text flow: run --f ../content/io/cloudslang/base/print/print_text.sl --i text=first_flow --cp ../content/

Command line arguments in the above example:

Argument	Description
--f	Location of the flow to run.
--i	Arguments the flow takes as input, for multiple arguments use a comma delimited list (e.g. `var1=value1,var2=value2`).
--cp	Classpath for the location of the content. Required when content imports other content.

Note: Some of the content is dependent on external python modules. If you are using the CLI to run your flows, you can import external modules by doing one of the following:

Installing packages into the python-lib folder
Editing the executable file

Installing packages into the python-lib folder:

Prerequisites: Python 2.7 and pip.

You can download Python (version 2.7) from [here] (https://www.python.org/). Python 2.7.9 and later include pip by default. If you already have Python but don't have pip, see the pip [documentation] (https://pip.pypa.io/en/latest/installing.html) for installation instructions.

Edit the requirements.txt file in the python-lib folder, which is found at the same level as the bin folder that contains the CLI executable.
Enter the Python package and all its dependencies in the requirements file.
- See the pip documentation for information on how to format the requirements file.
Run the following command from inside the python-lib folder:
```
pip install -r requirements.txt -t .
```
Note: If your machine is behind a proxy you will need to specify the proxy using pip's --proxy flag.

Note: If you have defined a JYTHONPATH environment variable, you will need to add the python-lib folder's path to its value.

Editing the executable file

Open the executable found in the bin folder for editing.
Change the Dpython.path key's value to the desired path.
