# User must be part of the `wheel` group for above line to be effective
# Lines beginning with `$' indicate conditional constructs.

# Customize Readline’s key bindings and make them whatever you like.
# Readline reads INPUTRC=~/.inputrc file on startup, given env-var
# INPUTRC is properly set in ~/.bash_profile, or in ~/.profile .

# Examples of ~/.inputrc are at:
# https://www.softpanorama.org/Scripting/Shellorama/Bash_as_command_interpreter/inputrc.shtml
# Common key sequences are:
# \C-<key>   Control key prefix
# \M-<key>   Meta (Escape) key prefix
# \e<key>    The escape character

set show-all-if-unmodified on
set editing-mode vi

## Mode config
set show-mode-in-prompt on
# vi insert mode has a blinking underscore as cursor
# default: prompt is prefixed with '(ins)'
set vi-ins-mode-string "+"\1\e[3 q\2
# vi normal/cmd mode has a blinking I beam as cursor
# default: prompt is prefixed with '(cmd)'
set vi-cmd-mode-string ":"\1\e[5 q\2

# CSI cursor style options '\e[<Ps>' for term w/ DECSCURSR support
# Supported by 'tmux' if 'set TERM=xterm-256color' in shell environment
# Source: https://invisible-island.net/xterm/ctlseqs/ctlseqs.html#h3-Functions-using-CSI-_-ordered-by-the-final-character_s_
#   Ps = 0  -> blinking block.
#   Ps = 1  -> blinking block (default).
#   Ps = 2  -> steady block.
#   Ps = 3  -> blinking underline.
#   Ps = 4  -> steady underline.
#   Ps = 5  -> blinking bar (xterm).
#   Ps = 6  -> steady bar (xterm).
# Surround options with \1...\2 to comply with readline syntax requirements
# Color can be added too: e.g. 'set vi-cmd-mode-string "\1\e[1;31m\2:\1\e[0m\2"'

## Macro for key binding:
# Ctrl+S: insert $(...)
#  Move to line begin with Ctrl+A ,put `$(` there.
#  Move to end of line with Ctrl+E then put `)` there.
"\C-s": "\C-a$(\C-e)"

# Alt+S: prefix cmd line with `sudo` and place cursor at end of line.
"\es": "\C-asudo \C-e"

# Section below obtained from terminal
#  $ bind -p | grep -v -e "(not bound)" -e "self-insert$" >> ~/.inputrc
