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 --select 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
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
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
If using oh-my-zsh, the autocompletion script can be installed by putting the _dbt file in the folder ~/.oh-my-zsh/completions/ (create the completions folder if it doesn't exist).
Add the following to your zshrc file:
zinit ice as"completion"
zinit snippet https://github.com/dbt-labs/dbt-completion.bash/blob/master/_dbt
If installing manually, instructions from zsh-completions mention that you need to include the directory where _dbt is stored in your $fpath by adding the following to ~/.zshrc
fpath=(path/to/_dbt/parent_directory $fpath)
And you may need to rebuild the zsh completion cache by running this in your terminal:
rm -f ~/.zcompdump; compinit
In many Linux distributions, the zsh package includes /usr/local/share/zsh/site-functions in its fpath, so simply copying _dbt in that directory should work.
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
This script uses the manifest 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.
By default the location of your manifest.json file is assumed to be at target/manifest.json. To change that you can specify the full path to the location of your manifest.json file in the environment variable DBT_MANIFEST_PATH. For example:
export DBT_MANIFEST_PATH=/tmp/dbt/target/manifest.jsonThis 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.
