如何使 zsh 函数从单词中间自动完成?
How do I make a zsh function autocomplet from the middle of a word?
我使用 zsh 并编写了一个函数来替换 cd 函数。在一些帮助下,我让它像我希望的那样工作(大部分)。这是
对于示例,假设您的目录如下所示:
/
a/
b/
c/
d/
some_dir/
我还假设已获取以下代码:
cl () {
local first=$( echo | cut -d/ -f1 )
if [ -d $first ]; then
pushd >/dev/null # If the first argument is an existing normal directory, move there
else
pushd ${PWD%/$first/*}/ >/dev/null # Otherwise, move to a parent directory or a child of that parent directory
fi
}
_cl() {
_cd
pth=${words[2]}
opts=""
new=${pth##*/}
local expl
# Generate the visual formatting and store it in `$expl`
_description -V ancestor-directories expl 'ancestor directories'
[[ "$pth" != *"/"*"/"* ]] && middle="" || middle="${${pth%/*}#*/}/"
if [[ "$pth" != *"/"* ]]; then
# If this is the start of the path
# In this case we should also show the parent directories
local ancestor=$PWD:h
while (( $#ancestor > 1 )); do
# -f: Treat this as a file (incl. dirs), so you get proper highlighting.
# -Q: Don't quote (escape) any of the characters.
# -W: Specify the parent of the dir we're adding.
# ${ancestor:h}: The parent ("head") of $ancestor.
# ${ancestor:t}: The short name ("tail") of $ancestor.
compadd "$expl[@]" -fQ -W "${ancestor:h}/" - "${ancestor:t}"
# Move on to the next parent.
ancestor=$ancestor:h
done
else
# $first is the first part of the path the user typed in.
# it it is part of the current direoctory, we know the user is trying to go back to a directory
first=${pth%%/*}
# $middle is the rest of the provided path
if [ ! -d $first ]; then
# path starts with parent directory
dir=${PWD%/$first/*}/$first
first=$first/
# List all sub directories of the $dir/$middle directory
if [ -d "$dir/$middle" ]; then
for d in $(ls -a $dir/$middle); do
if [ -d $dir/$middle/$d ] && [[ "$d" != "." ]] && [[ "$d" != ".." ]]; then
compadd "$expl[@]" -fQ -W $dir/ - $first$middle$d
fi
done
fi
fi
fi
}
compdef _cl cl
问题:
在我的 zshrc 中,有一行:
zstyle ':completion:*' matcher-list 'm:{a-z}={A-Za-z}' '+l:|=* r:|=*'
这应该使自动完成不区分大小写,并确保我可以开始输入目录名称的最后一部分,并且仍然会完成全名
示例:
$ cd /a
$ cd di[tab] # replaces 'di' with 'some_dir/'
$ cl di[tab] # this does not do anything. I would like it to replace 'di' with 'some_dir'
如何让它在我输入 'di' 时提示 'some_dir'?
你的 matcher-list
中的第二个匹配器永远不会被调用,因为 _cl()
return 的“真”(实际上是退出状态 0
)即使它没有添加任何匹配项。返回“true”会导致 _main_complete()
假设我们已经完成,因此它不会尝试列表中的下一个匹配器。
要解决此问题,请将以下内容添加到 _cl()
的开头:
local -i nmatches=$compstate[nmatches]
到 _cl()
结尾:
(( compstate[nmatches] > nmatches ))
这样,_cl()
只有在成功添加完成后才会 return “真”。
