Getting Started

Popper is a convention for organizing an academic article’s artifacts following a DevOps approach, with the goal of making it easy for others (and yourself!) to repeat an experiment or analysis pipeline.

We first need to install the CLI tool by following these instructions. Show the available commands:

popper --help

Show which version you installed:

popper version
NOTE: this exercise was written using 1.0.0

Create a project repository (if you are not familiar with git, look here):

mkdir mypaper
cd mypaper
git init
echo '# mypaper' >
git add .
git commit -m 'first commit'

Initialize the popper repository and add the .popper.yml file to git:

popper init
git add .
git commit -m 'adds .popper.yml file'

New pipeline

Initialize pipeline using init (scaffolding):

popper init myexp

Show what this did:

ls -l pipelines/myexp

Commit the “empty” pipeline:

git add pipelines/myexp
git commit -m 'adding myexp scaffold'

Popper Run

Run popper run:

popper run

Once a pipeline is executed, one can show the logs:

ls -l pipelines/myexp/popper_logs

Adding Project to GitHub

Create a repository on github, register the remote repository to your local git and push all your commits:

git remote add origin<user>/<repo>
git push -u origin master

where <user> is your username and <repo> is the name of the repository you have created.

Adding Project to Travis

For this, we need to login to Travis CI using our Github credentials. Once this is done, we activate the project so it is continuously validated.

Generate .travis.yml file:

popper ci --service travis

And commit the file:

git add .travis.yml
git commit -m 'Adds TravisCI config file'

Trigger an execution by pushing to github:

git push

Go to TravisCI website to see your experiments being executed.
