.inputrc

# inputrc configures line editing functionality provided by the readline
# library, used by many interactive programs such as the bash shell. See:
#    info '(bash)Readline Init File Syntax'
# https://www.gnu.org/software/bash/manual/html_node/Readline-Init-File-Syntax.html
#
# BSDs and macOS use editline, with a readline compatibility layer at least in
# the case of macOS. See `man editrc` and `man editline`.

# Filetype colors in completion lists
set colored-stats on

# Case-insensitive filesystems be damned

set completion-map-case on

# With multiple matches, only show the remaining part.
# Unsupported in editline  >:-(

# Try to avoid accidental multi-line pastes being interpreted as commands
set enable-bracketed-paste on

# Completion when in middle of word doesn't duplicate existing input.
# Like many useful GNU things, seems unsupported in editline.

# Automatically complete directory symlinks with ending /
# Also offers them for `complete -d` like cd & pushd

# Show completions immediately if multiple matches
set show-all-if-ambiguous on
set show-all-if-unmodified on

# -- Key Bindings -------------------------------------------------------------
# Symbolic keynames like Esc-j appear unsupported by editline.
