I want to use it with menu selection.
To use this,
1) source this file.
% source auto-fu.zsh
2) establish `zle-line-init' containing `auto-fu-init' something like below.
% zle-line-init () {auto-fu-init;}; zle -N zle-line-init
3) use the _oldlist completer something like below.
% zstyle ':completion:*' completer _oldlist _complete
(If you have a lot of completer, please insert _oldlist before _complete.)
4) establish `zle-keymap-select' containing `auto-fu-zle-keymap-select'.
% zle -N zle-keymap-select auto-fu-zle-keymap-select
(This enables the afu-vicmd keymap switching coordinates a bit.)
*Optionally* you can use the zcompiled file for a little faster loading on
every shell startup, if you zcompile the necessary functions.
*1) zcompile the defined functions. (generates ~/.zsh/auto-fu.zwc)
% A=/path/to/auto-fu.zsh; (zsh -c "source $A ; auto-fu-zcompile $A ~/.zsh")
*2) source the zcompiled file instead of this file and some tweaks.
% source ~/.zsh/auto-fu; auto-fu-install
*3) establish `zle-line-init' and such (same as a few lines above).
Note:
It is approximately *(6~10) faster if zcompiled, according to this result :)

0.004 ( source ~/.zsh/auto-fu; auto-fu-install; )
Here is the auto-fu-zcompile manual.

NAME
auto-fu-zcompile - zcompile auto-fu
SYNOPSIS
auto-fu-zcompile <auto-fu.zsh file> <directory to output>
[<restoffiles>...]
DESCRIPTION
This command dumps out the auto-fu's functions, zle and stuff to
<directory to output>/auto-fu. This is inspired from `compinit' which
dumps out the completion system's internal stuff to ~/.zcompdump.
Then `zrecompile' the <directory to output>/auto-fu.
As you can see, auto-fu.zsh has some `eval' calls, so it may result
poor loading performance. I want to avoid that as far as possible, so
the resulting file (~/.zsh/auto-fu) has fewer `eval's and stripped
unnecessary things at runtime.
afu+* and auto-fu* widgets and afu+* functions will *NOT* be
stripped by auto-fu-zcompile.
OPTIONS
<auto-fu.zsh file>
This file.
<directory to output>
Directory to dumped and zcompiled files reside.
[<restoffile>...]
Files to be `source'ed right before the dumped file creation.
auto-fu-zcompile will strip unnecessary stuff, so some utility
shell functions will not be available at runtime. If you want
to customize auto-fu stuff using auto-fu.zsh's internal
functions, you can code it at this point (example below).
EXAMPLES
. zcompile auto-fu in ~/.zsh.d:
% A=/path/to/auto-fu.zsh
% (zsh -c "source $A ; auto-fu-zcompile $A ~/.zsh.d")
. Customize some not-easily-customizable things:
% A=/path/to/auto-fu.zsh
% (zsh -c "source $A ; \
auto-fu-zcompile $A ~/.zsh.d ~/.zsh/auto-fu-customize.zsh")
'~/.zsh/auto-fu-customize.zsh' is something like this:
>
afu+my-kill-line-maybe () {
if (($#BUFFER > CURSOR));
then zle kill-line
else zle kill-whole-line
fi
}
zle -N afu+my-kill-line-maybe
afu-register-zle-eof \
afu+orf-ignoreeof-deletechar-list \
afu-ignore-eof afu+my-kill-line-maybe
afu-register-zle-eof \
afu+orf-exit-deletechar-list exit afu+my-kill-line-maybe
<
Using `afu-register-zle-eof' to customize the <C-d> behaviors.

Configuration
The auto-fu features can be configured via zstyle.
:auto-fu:highlight
input
A highlight specification used for user input string.
completion
A highlight specification used for completion string.
completion/one
A highlight specification used for completion string if it is the
only one candidate.
:auto-fu:var
postdisplay
An initial indication string for POSTDISPLAY in auto-fu-init.
postdisplay/clearp
If set, POSTDISPLAY will be cleared after the accept-lines.
'yes' by default.
enable
A list of zle widget names the automatic complete-word and
list-choices to be triggered after its invocation.
Only with ALL in 'enable', the 'disable' style has any effect.
ALL by default.
disable
A list of zle widget names you do *NOT* want the complete-word to be
triggered. Only used if 'enable' contains ALL. For example,
zstyle ':auto-fu:var' enable all
zstyle ':auto-fu:var' disable magic-space
yields; complete-word will not be triggered after pressing the
space-bar, otherwise automatic thing will be taken into account.
track-keymap-skip
A list of keymap names to *NOT* be treated as a keymap change.
In other words, these keymaps cannot be used with the standalone main
keymap. For example "opp". If you use my opp.zsh, please add an 'opp'
to this zstyle.
autoable-function/skipwords
autoable-function/skiplbuffers
autoable-function/skiplines
A list of patterns to *NOT* be treated as auto-stuff appropriate.
These patterns will be tested against the part of the command line
buffer as shown on the below figure:
(*) is used to denote the cursor position.
# nocorrect aptitude --assume-*yes -d install zsh && echo ready
<-------->skipwords
<----------------->skiplbuffers
<----------------------------------->skplines
Examples:
- To disable auto-stuff inside single and also double quotes.
And less than 3 chars before the cursor.
zstyle ':auto-fu:var' autoable-function/skipwords \
"('|$'|")*" "^((???)##)"
- To disable the rm's first option, and also after the '(cvs|svn) co'.
zstyle ':auto-fu:var' autoable-function/skiplbuffers \
'rm -[![:blank:]]#' '(cvs|svn) co *'
- To disable after the 'aptitude word '.
zstyle ':auto-fu:var' autoable-function/skiplines \
'([[:print:]]##[[:space:]]##|(#s)[[:space:]]#)aptitude [[:print:]]# *'
autoable-function/preds
A list of functions to be called whether auto-stuff appropriate or not.
These functions will be called with the arguments (above figure)
- $1 '--assume-'
- $2 'aptitude'
- $3 'aptitude --assume-'
- $4 'aptitude --assume-yes -d install zsh'
For example,
to disable some 'perl -M' thing, we can do by the following zsh codes.
>
afu-autoable-pm-p () { [[ ! ("$2" == 'perl' && "$1" == -(#i)m*) ]] }
# retrieve default value into 'preds' to push the above function into.
local -a preds; afu-autoable-default-functions preds
preds+=afu-autoable-pm-p
zstyle ':auto-fu:var' autoable-function/preds $preds
<
The afu-autoable-dots-p is actually an example of this ability to skip
uninteresting dots.
autoablep-function
A predicate function to determine whether auto-stuff could be
appropriate. (Default `auto-fu-default-autoable-pred' implements the
above autoablep-function/* functionality.)
Configuration example
zstyle ':auto-fu:highlight' input bold
zstyle ':auto-fu:highlight' completion fg=black,bold
zstyle ':auto-fu:highlight' completion/one fg=white,bold,underline
zstyle ':auto-fu:var' postdisplay $'
-azfu-'
zstyle ':auto-fu:var' track-keymap-skip opp
#zstyle ':auto-fu:var' disable magic-space
XXX: use with the error correction or _match completer.
If you got the correction errors during auto completing the word, then
plese do _not_ do `magic-space` or `accept-line`. Insted please do the
following, `undo` and then hit <tab> or throw away the buffer altogether.
This applies _match completer with complex patterns, too.
I'm very sorry for this annonying behaviour.
(For example, 'ls --bbb' and 'ls --*~^*al*' etc.)
XXX: ignoreeof semantics changes for overriding ^D.
You cannot change the ignoreeof option interactively. I'm verry sorry.
To customize the ^D behavior further, it will be done for example above
auto-fu-zcomple manual's EXAMPLE section's code. Please take a look.
