RSE-Sheffield.github.io

Source code for the Research Software Engineering @ Sheffield website. Built using Nikola (https://getnikola.com/). The source for this site is maintained on the devel branch and rendered content is deployed to the master branch.

Read on to learn how you can contribute to this site and about how the site is built, tested and deployed.

Installation on macOS / Linux using conda

First clone this repo and cd into its directory.

Install conda (we recommending doing a regular install of Miniconda). Then:

conda create --name rse-blog python=3.6
source activate rse-blog
pip install --upgrade -r "requirements.txt"

Note that the python=3.6 above will work even if you don't think you have Python 3 installed. conda creates an environment and installs Python 3 into it from its own packages.

On macOS you may also need to add the following to your ~/.bashrc:

export DYLD_LIBRARY_PATH=${HOME}/anaconda/envs/nikola/lib/

Installation on macOS / Linux using venv

An alternative approach is to forgo using conda and install into a venv (a different type of Python virtual environment).

First clone this repo and cd into its directory.

sudo apt-get install python3-venv  # or the macOS equivalent
# Create a directory to house your venvs
mkdir ~/.venvs
# Create the venv
python3.6 -m venv ~/.venvs/rse-blog
# Activate the venv
source ~/.venvs/rse-blog/bin/activate
# Install dependencies via pip, including wheel and nikola
pip install --upgrade -r "requirements.txt"

Writing a blog post

Install Nikola (the above installation will have installed Nikola into either a conda or a virtualenv environment).

Fork this repo, clone it to your machine and enter the directory.

Create a file in the posts directory. It will need to start with a header like this:

<!--
.. title: Accelerated versions of R for Iceberg
.. author: Mike Croucher
.. slug: intel-R-iceberg
.. date: 2016-09-12 00:31:35 UTC
.. tags:
.. category:
.. link:
.. description:
.. type: text
-->

The slug refers to the end of the URL and it will need to be unique.

You can build and test your post on your own machine using:

cd site
nikola build

If the build is OK, you can look at it on your browser with

nikola serve --browser

As an alternative to repeatedly running nikola build every time you make a change you can run:

nikola auto

to detect changes, automatically rebuild your site and refresh your browser.

When you are happy, submit a Pull Request.

Formatting tips

• When editing a Markdown page make sure you leave a blank line before any bulleted lists.

Site testing and deployment

When you create a pull request against this repo or push to a branch in this repo, travis-ci.org:

1. Checks that the site can be built
2. Then, if the build was triggered by a push to devel, deploys the rendered content to the master branch.
   NB Travis CI deployment tasks never run for builds triggered by pull requests.

See .travis.yml for more info and see this guide for how to set up Travis-driven deployment.
