Tab completion

Tab completion can complete config groups, config nodes and values. To complete paths, start them with / or ./.

See this short video demonstration of tab completion:

Install tab completion

Get the exact command to install the completion from --hydra-help. Currently, Bash, zsh and Fish are supported. We are relying on the community to implement tab completion plugins for additional shells.

Fish instructions

Fish support requires version >= 3.1.2. Previous versions will work but add an extra space after ..

Because the fish shell implements special behavior for expanding words prefixed with a tilde character '~', command-line completion does not work for tilde deletions.

Zsh instructions

Zsh is compatible with the existing Bash shell completion by appending

autoload -Uz bashcompinit && bashcompinit

to the .zshrc file after compinit, restarting the shell and then using the commands provided for Bash.

Because the zsh shell implements special behavior for expanding words prefixed with a tilde character '~', command-line completion does not work for tilde deletions.
