Running with the CLI

Phaser includes a command-line tool that can run an existing pipeline on a new source.

As an example, if you have cloned the phaser repository, you can run the EmployeeReviewPipeline in the tests/pipeline directory. Running on the command-line will produce the warnings and errors with row numbers that persist throughout the pipeline.

% cd tests
% python -m phaser run employees ~/phaser_output fixture_files/employees.csv
Running pipeline 'EmployeeReviewPipeline'

% cat ~/phaser_output/errors_and_warnings.txt
