What

This script adds autocompletion to the dbt CLI. Once installed, users can tab-complete model, tag, source, and package selectors to node selection flags like --models and --exclude. Need a refresher on resource selection? Check out the docs.

Example usage (using the redshift package):

$ dbt run --model red<TAB>
redshift.*                                  redshift_admin_queries                      redshift_constraints
redshift.base.*                             redshift_admin_table_stats                  redshift_cost
redshift.introspection.*                    redshift_admin_users_schema_privileges      redshift_sort_dist_keys
redshift.views.*                            redshift_admin_users_table_view_privileges  redshift_tables
redshift_admin_dependencies                 redshift_columns

Installation (bash)

This script can be installed by moving it to your home directory (as a dotfile), then sourcing it in your ~/.bash_profile file.

curl https://raw.githubusercontent.com/fishtown-analytics/dbt-completion.bash/master/dbt-completion.bash > ~/.dbt-completion.bash
echo 'source ~/.dbt-completion.bash' >> ~/.bash_profile

Installation (zsh)

The z shell requires a bit more work, you'll also want to automatically load compinit and bashcompinit if they are not already loaded.

This makes use of zsh's ability to import bash completion scripts and use them, as long as they're script-compatible.

curl https://raw.githubusercontent.com/fishtown-analytics/dbt-completion.bash/master/dbt-completion.bash > ~/.dbt-completion.bash
echo 'autoload -U +X compinit && compinit' >> ~/.zshrc
echo 'autoload -U +X bashcompinit && bashcompinit' >> ~/.zshrc
echo 'source ~/.dbt-completion.bash' >> ~/.zshrc

Bash Completion

In bash, the : character counts as a word separator, which causes this completion script to incorrectly handle selectors like tag:... and source:.... To make the script work with these characters, install the bash-completion program, then re-source the dbt-completion.bash script.

macOS

$ brew install bash-completion

Notes and caveats

This script uses the manifest (assumed to be at target/manifest.json) to quickly provide a list of existing selectors. As such, a dbt resource must be compiled before it will be available for tab completion. In the future, this script should use dbt directly to parse the project directory and generate possible selectors. Until then, brand new models/sources/tags/packages will not be displayed in the tab complete menu.

This script was tested on macOS using bash 4.4.23. It's very likely that this script will not work as expected on other operating systems or in other shells. If you're interested in helping make this script work on another platform, please open an issue!

On zsh, when you want to use the project.folder.* notation, you may have to prefix with a quote, as otherwise you'll get autocompleted to something like dbt compile -m project.folder.*, and zsh will try to glob, find no matches, and throw an error.

You can’t perform that action at this time.
