# Executed by Readline when a program starts the Readline library
#
# Options that take a string parameter cannot have a comment next to them, e.g.
# `set bell-style none # Some comment` will not work.

# Completion configuration
#
# It's worth noting what's going on here since it's not clear from the
# documentation.
#
# There are three cases to cover for the behavior I want:
# - Only one match → complete
# - Multiple matches → show the list
# - Multiple matches with common prefix → complete prefix and show the list
#
# By default, `menu-complete()` will select the first completion, this covers
# the first case. `show-all-if-ambiguous` covers the second case by showing the
# list when there are multiple choices. `menu-complete-display-prefix` covers
# the third case by completing the common prefix.
set show-all-if-ambiguous on
set menu-complete-display-prefix on
set editing-mode vi # Vi keybindings
set match-hidden-files off # Don't match hidden files, unless a leading '.' is typed explicitly
set completion-ignore-case on # Ignore case when matching completions
set search-ignore-case on # Ignore case when searching
set skip-completed-text on # Don't insert match when completing in the middle of a word
set completion-query-items 100 # Prompt before showing more than this number of completions
set completion-display-width -1 # Use all available width to show completions
set print-completions-horizontally on # Sort completions horizontally
set colored-stats on # Show completions using colors depending on file type
set visible-stats on # Append a character denoting file type
set colored-completion-prefix on # Color the common prefix of completions
set expand-tilde off # Don't expand tilde automatically
set show-mode-in-prompt on # Show current mode (vi-insert, vi-command) in prompt
# String to display for each mode
set vi-cmd-mode-string -CMD-
set vi-ins-mode-string -INS-
# Don't ring the terminal bell
set bell-style none
