.inputrc

# ~/.inputrc — readline configuration
# Applies to every program using GNU readline (bash, psql, python, gdb, ...).

# By default, readline re-binds terminal special characters (the ones set via
# stty, e.g. C-w = werase, C-u = kill-line) to their tty meaning, overriding
# any custom bindings. Turning this off lets the "\C-w" binding below take
# effect instead of being clobbered by the terminal driver.
# See http://lists.gnu.org/archive/html/bug-bash/2009-03/msg00033.html
set bind-tty-special-chars off

# Never ring the terminal bell (no audible beep, no visual flash),
# e.g. on ambiguous completion or when there is nothing to complete.
set bell-style none

# --- Emacs-style region bindings ---------------------------------------------

# C-@ (Ctrl-Space sends this): set the mark at point, like Emacs' set-mark.
"\C-@": set-mark

# C-w: kill (cut) the text between mark and point into the kill ring,
# like Emacs' kill-region. Only works because bind-tty-special-chars is off,
# otherwise C-w would stay the terminal's "delete previous word".
"\C-w": kill-region

# M-w: copy the region between mark and point into the kill ring without
# deleting it, like Emacs' copy-region-as-kill. Paste with C-y (yank).
"\M-w": copy-region-as-kill

# --- Completion --------------------------------------------------------------

# When menu-completing, first insert the common prefix of all matches
# before cycling through the individual candidates.
set menu-complete-display-prefix on

# If a completion is ambiguous, list all matches immediately on the first
# TAB press instead of requiring a second one.
set show-all-if-ambiguous on

# Colorize completion candidates by file type (like ls --color),
# using the LS_COLORS environment variable.
set colored-stats on

# Highlight the common prefix of the completion candidates in color.
set colored-completion-prefix on

# Case-insensitive completion: "doc<TAB>" also matches "Documents".
set completion-ignore-case on

# TAB cycles forward through the completion candidates (menu completion)
# instead of just inserting the longest common prefix.
TAB: menu-complete

# Shift-TAB (terminals send the CSI Z escape sequence) cycles backward
# through the completion candidates.
"\e[Z": menu-complete-backward

# If the text after the cursor already matches the completion, skip over it
# instead of inserting a duplicate. E.g. cursor in the middle of "Makefile"
# won't produce "Makefileile".
set skip-completed-text on

# Print all completion candidates at once instead of paging them through
# an internal more-style prompt.
set page-completions off

# Always just show me the competions options, even if there are many.
set completion-query-items -1

# Treat hyphens and underscores as equivalent during completion, so
# "my_dir<TAB>" matches "my-dir". Only works with completion-ignore-case on,
# which you have. Great for projects that mix naming styles.
set completion-map-case on

# --- History -----------------------------------------------------------------

# Edited-then-abandoned history entries: if you recall an old command, modify
# it, but then move to another entry and run that instead, readline normally
# keeps your edits on the abandoned entry for the rest of the session.
# This reverts all such stray edits when you hit Enter.
set revert-all-at-newline on

# Up arrow: search history backward for entries starting with the text
# already typed on the line (prefix search instead of plain previous-entry).
"\e[A": history-search-backward

# Down arrow: same as above, but search forward through history.
"\e[B": history-search-forward

# --- Misc --------------------------------------------------------------------

# Paste multiline clipboard content as a single editable blob instead of
# executing each line on its embedded newlines. Default since readline 8.1,
# but stating it protects you on older hosts — it's a real safety feature.
set enable-bracketed-paste on

# Don't echo control characters; e.g. pressing C-c won't display "^C"
# on the line before the signal takes effect.
set echo-control-characters off
