Command-Line Utility

Dallinger is executed from the command line within the experiment directory with the following commands:

verify

Verifies that a directory is a Dallinger-compatible app.

debug

--verbose

Runs the experiment locally. If --verbose is included more detailed logs are printed to the command line.

sandbox

--verbose

--app <name>

Runs the experiment on MTurk’s sandbox using Heroku as a server. If --verbose is included more detailed logs are printed to the command line. If --app is specified the app on heroku will have that name.

deploy

--verbose

--app <name>

Runs the experiment live on MTurk using Heroku as a server. If --verbose is included more detailed logs are printed to the command line. If --app is specified the app on heroku will have that name.

logs

--app <app>

Opens the app’s logs in Papertrail.

status

Returns the status of an experiment.

export

Downloads the database and partial server logs to a zipped folder within the data directory of the experimental folder. Databases are stored in csv format.

summary

--app <app-id>

Prints a summary of the participant table to the command line. You must specify the app id.

qualify

--qualification <qualification_id>

--value <value>

--worker <worker_id>

Assigns qualification qualification_id with value value to worker worker_id. This is useful when compensating workers if something goes wrong with the experiment.

hibernate

--app <app>

Temporarily scales down the specified app to save money. All dynos are removed and so are many of the add-ons. Hibernating apps are non-functional. It is likely that the app will not be entirely free while hibernating. To restore the app use awaken.

awaken

--app <app>

Retore a hibernating app.
