# neo4j Bash Completion
# =======================
#
# Bash completion support for the `neo4j` command,
# generated by [picocli](https://picocli.info/) version 4.7.7.
#
# Installation
# ------------
#
# 1. Source all completion scripts in your .bash_profile
#
#   cd $YOUR_APP_HOME/bin
#   for f in $(find . -name "*_completion"); do line=". $(pwd)/$f"; grep "$line" ~/.bash_profile || echo "$line" >> ~/.bash_profile; done
#
# 2. Open a new bash console, and type `neo4j [TAB][TAB]`
#
# 1a. Alternatively, if you have [bash-completion](https://github.com/scop/bash-completion) installed:
#     Place this file in a `bash-completion.d` folder:
#
#   * /etc/bash-completion.d
#   * /usr/local/etc/bash-completion.d
#   * ~/bash-completion.d
#
# Documentation
# -------------
# The script is called by bash whenever [TAB] or [TAB][TAB] is pressed after
# 'neo4j (..)'. By reading entered command line parameters,
# it determines possible bash completions and writes them to the COMPREPLY variable.
# Bash then completes the user input if only one entry is listed in the variable or
# shows the options if more than one is listed in COMPREPLY.
