Readline Init File

This is basically a steaming piece of shit that's unusable.

See also:

• .bashrc

---

• ~/.inputrc doesn't work in PCLinuxOS .92
• /etc/inputrc
• man bash and man readline should help (but don't really.. since they're man pages and those aren't very useful)
• I was unable to find a keyboard map online. How sad is that?!

• control-v and then the character or keystroke combination to learn what it is. To use it, replace control with \e and replace [[ with [

Customization ∞

## Page up/down (scroll through history)
# This leaves the cursor where it is, but should instead put the cursor at the end (and continue allowing up/down to cycle through that chunk of history)
# One way (fails):
#"\eOa": history-search-backward  ## control+up-arrow
#"\eOb": history-search-forward   ## control+down-arrow
# Alternate terminal type (fails):
#"\e[2A": history-search-backward ## shift+up-arrow
#"\e[2B": history-search-forward  ## shift+down-arrow
# success with PCLinuxOS .92
"\e[[5~": history-search-backward ## pageup
"\e[[6~": history-search-forward  ## pagedown

## ctrl-left and right (navigate words)
# One way (fails):
#"\eOd": backward-word
#"\eOc": forward-word
# Alternate terminal type (success with PCLinuxOS .92)
"\e[1;5D": backward-word
"\e[1;5C": forward-word

## Make tab cycle through alternates, instead of blocking typing and showing the list.
"\t": menu-complete

F-keys ∞

This stuff puts a tilde ( ~ ) on the next line!

"\e[OP":"echo ok"	#F1
"\e[OQ"		#F2
"\e[OR"		#F3
"\e[OS"		#F4
"\e[15"		#F5
"\e[17"		#F6
"\e[18"		#F7
"\e[19"		#F8
"\e[20"		#F9
"\e[21"		#F10
"\e[23"		#F11
"\e[24":"echo ok\C-M"	#F12

To do ∞

shift-tab should go through the complete list backwards.

control-backspace and control-delete ∞

Apparently these were made really difficult to fix.

I may need to fiddle with the x keyboard driver to remap these hotkeys, and then I could have inputrc modified to use the remapping.

? ## ctrl-backspace
? ## ctrl-delete

Is the right file to use this?:

/usr/lib/kbd/keymaps/i386/qwerty/defkeymap.kmap.gz

Notes from William Park ∞

man bash

man readline

- history-search-forward
- history-search-backward
- .inputrc

For searching through the history, above should be enough, eg.

C-p: history-search-backward
C-n: history-search-forward

which can be bound to some other keys of your choice.

For searching through previously visited directories, it's more complicated. You can easily build up a large list. So, you need

• some random access into "partial match", or

• moving sequentially for few last directories that you can actually remember.

The key insight is "Programmable Completion" (man bash). To make long story short, put this in ~/.profile.

_cd ()
{
    local cur=${COMP_WORDS[$COMP_CWORD]}

    COMPREPLY=( $(compgen -W "`dirs`" -- $cur) )
}
cd () { pushd "${1:-$HOME}" ; }
alias b='pushd'             # swap current and previous
alias p='popd'              # pop the current, and go back to previous

complete -o dirnames -F _cd cd
complete -d popd pushd

1.

• cd will push the new directory onto stack,
• p will pop and move to previous directory.

• b will toggle between current and previous, ie. swap the 2 items on the stack.

2. When you press <Tab>, eg.

cd /usr<TAB>

it will try to complete on '/usr' from 'dirs' output. If no completion is possible, then only the directories will be listed.

Main problem is that if your 'dirs' has

/usr/local/src/bash ~

then typing

cd /<Tab>

will return

cd /usr/local/src/bash

This is okay if you wanted to go to /usr/local/src/bash, but not if you wanted some other directory under /, like /var/log. For the latter case, you have to type more chars, eg.

cd /v<Tab>
