Lazybones templates for emews projects.

See for lazybones install info

Installing the Templates

The source for the templates is in the template folder. To install the templates so that they can be used via lazybones:

./gradlew installTemplateEmews

Publishing the Templates

The templates can be published to the emews/emews-templates bintray repository with

./gradlew publishTemplateEmews

This requires a file in the top directory with two properties:


This file is not under version control for security reasons.

Running the Templates

The repository contains an emews template and 3 subtemplates sweep, eqpy, and eqr. The command

lazybones create emews 0.0 X

will create an EMEWS project structure in director X, using version 0.0 of the template. For example

lazybones create emews 0.0 swift_project

will create the default EMEWS project structure in a swift_project directory.


The directories are intended to contain the following:

  • data - model input etc. data
  • etc - additional code used by EMEWS
  • ext - swift-t extensions such as eqpy, eqr
  • python - python code (e.g. model exploration algorithms written in python)
  • python\test - tests of the python code
  • R - R code (e.g. model exploration algorithms written R)
  • R\test - tests of the R code
  • scripts - any necessary scripts (e.g. scripts to launch a model), excluding scripts used to run the workflow.
  • swift - swift code


The subtemplates will populate the above directories with files appropriate for the type of workflow associated with that subtemplate. The subtemplates are executed with the command:

lazybones generate X

where X is the subtemplate name: sweep, eqpy, or eqr. Once the subtemplate has been generated the files can be edited to suit the current purpose. The files themselves contain comments to guide the customization. The subtemplates must be generated from within the directory created by the top-level emews template. Subtemplate generation will query the user for additional information (e.g. the model name) required to generate the template.


The sweep subtemplate generates files appropriate for a sweep through a collection of parameters, running the model for each set of parameters. By default, the parameters are defined in a input file where each line is a set of parameters to run.

  • swift/ - bash script used to launch the workflow
  • swift/swift_run_sweep.swift - swift script that will iterate through an input file, passing each line of that input to a model. The model is called from an app function.
  • (optional) scripts/ - the actual name of this file is derived from user input during the subtemplate generation. The file is a bash script that should be edited to call the model. The app function in swift_run_sweep.swift calls this file.


The eqpy subtemplate generates files and code for model exploration using the EQ/Py EMEWS extension. This extension allows model runs and exploration to be controlled from a python code algorithm.

The template installs the EQ/Py extension in ext/EQ-Py. The extension consists of two files.

  • ext/EQ-Py/
  • ext/EQ-Py/EQPy.swift

These should not need to be edited by the user.

The remaining files are generated in the swift/ directory. Note that the file names are determined by user input and the names below are defaults.

  • swift/ - bash script used to launch the EQ/Py-based workflow.
  • swift/swift_run_eqpy.swift - a skeleton swift script for model exploration runs whose parameters are generated from a python algorithm. See the TODOs in the script for additional instructions.
