history-search + a few new user question

[karpi]

Hello, Ive just try switch from bash. zsh has plenty of amazing
features, but some, i am habit-dependent on, i can not found.

1) At first there was my mostly touched function:
-type some chars, which command begins, and then call completation from
history. Yes there is history-search-backward history-search-forward,
but they are "first word based" -->
gvim .z<touch-key_history-search-backward> do not complete .zshrc from
history, but offers: gvim something, gvim /something/other, gvim
/something/which/i/do/not/needs.now ...
I would like get only "gvim .z" based lines from history.
Im clear? Is there some function, or way to set this, plz..?

2) some way to set "ignorerece" so
cd downloads
interprets as too
cd DownLoads 

3) Some way to colorize wrong symliks differently from good pointed
symlinks (for example cyan-good/red-bad like gentoo default bash setting)? 

3) when I press Alt-backspace, cursor deletes all path. Is possible it
deletes only part of path limited by "/"

cd /q/w/e/r/some_bad<touch>
cd 
:( -- I would like:
cd /q/w/e/r/some_bad<touch>
cd /q/w/e/r/

                                    Thanx for your care,

I dislike the history-search-Xward functions too. Luckily, there's:
history-beginning-search-backward (and ...-forward)
which does exactly the desired thing.

That's because zsh by default considers "/" to be part of a word instead of a 
separator (defined in the WORDCHARS parameter). I remove "/" in my .zshrc:
WORDCHARS=${WORDCHARS//\/}
This also causes backward-word etc. to stop on "/".

hope this helps,

Christian

Not exactly, but you can define a hash for that:

hash -d downloads=~/DownLoads
cd downloads -> ~/DownLoads

That is done through the LS_COLORS variable, AFAIK.

You might want to look at

    autoload -U select-word-style
    select-word-style bash

and

    bashcompinit

I believe these are all mentioned in the manual.

} 1) At first there was my mostly touched function:
} -type some chars, which command begins, and then call completation from
} history.

Do you want words from the history completed, or entire lines from the
history found?  The term "completion" usually means individual words,
not whole lines.

I suspect what you want is history-beginning-search-* as Christian T.
already suggested.  However, also look for history-search-end in the
"ZLE Functions" section of "User Contributions" chapter in the manual.

} 2) some way to set "ignorerece" so

"rece"?  Hmm, must be Czech?

However, I see what you're getting at, and the answer is no, there is
not in general a way to make zsh behave that way unless the underlying
filesystem does so (like in cygwin).

} cd downloads
} interprets as too
} cd DownLoads 

For specific cases, such as "cd", you can fix it:

    function cd {
	emulate -LR zsh
	setopt extendedglob nonomatch
	local -a opts
	zparseopts -D -a opts s L P
	if [[ $# -eq 2 ]]
	then builtin cd $opts $1 $2
	else builtin cd $opts (#i)$*
	fi
    }

} 3) Some way to colorize wrong symliks differently from good pointed
} symlinks (for example cyan-good/red-bad like gentoo default bash setting)? 

Look in the manual for "The zsh/complist Module".

} 3) when I press Alt-backspace, cursor deletes all path. Is possible it
} deletes only part of path limited by "/"

See "select-word-style bash" as mentioned above.

Well, there's the option "nocaseglob", which interprets patterns that way,
but the problem is "downloads" is a simple string which isn't treated as a
pattern (which is why Bart didn't bother mentioning the option).  You can
use tricks to force it to be a pattern, but you'll probably think they're
too clumsy to use:

% setopt nocaseglob
% echo downloads(/)
DownLoads

Basically, anything which (1) is a pattern of some sort (2) only matches
the thing you want will do the trick.  The pattern here picks out all
directories called downloads, but using the normal globbing rules, so
"nocaseglob" is applied.

Another useful thing to know about (again, not quite what you asked for) is
completion's matching control, which allows it to match case-insenstively.
Assuming you are using the new completion system, try this setting:

zstyle ':completion:*' matcher-list '' 'm:{a-zA-Z}={A-Za-z}'

(You don't need "nocaseglob" for this).  Now you can type:

% cd downloads<TAB>

and the completion system will work out that the file you want is called
DownLoads and change it.  This will work for any file, indeed any form of
completion that doesn't replace the matcher list.

Use the following line, it makes all completions case-insensitive:
zstyle ':completion:*' matcher-list 'm:{a-zA-Z}={A-Za-z}'
