使用下面的代码,一切都按预期进行:
当我书写
c
并按下TAB
按键时,我会按正确的顺序获得适当的完成。当我书写
./
并按下TAB
按键时,我得到了标签的完成executables
。
# Always use menu selection when using unambiguous completions.
zstyle ':completion:*:*:*:*:*' menu 'select'
# Show only completions.
zstyle ':completion:*:*:*:*:*' completer _complete
# Group name becomes the name of the matching tag.
zstyle ':completion:*:*:*:*:*' group-name ''
# Configure the order of tag matching as well as their descriptions.
zstyle -e ':completion:*:*:-command-:*:*' tag-order '
reply=(

'
# Configure the order in which completion groups will be shown.
zstyle ':completion:*:*:-command-:*:*' group-order 'Executables' 'Builtins' 'Commands' 'Aliases' 'Functions' 'Variables' 'Keywords'
# Configure the format for each group/tag description.
zstyle ':completion:*:*:*:*:descriptions' format $'%{\e[0;38;2;0;0;0;48;2;200;150;0m%} %d %{\e[0;38;2;200;150;0;48;2;0;0;0m%}%{\e[0m%}'
# Initialize completion system.
autoload -Uz compinit && compinit
但是,如果我指定的标签没有产生任何完成,那么也会尝试其他标签。
functions
证明这一点的最简单方法是从样式中排除标签tag-order
:
zstyle -e ':completion:*:*:-command-:*:*' tag-order '
reply=(
"executables:Executables:Executables
builtins:Builtins:Builtins
commands:Commands:Commands
aliases:Aliases:Aliases
parameters:Variables:Variables
reserved-words:Keywords:Keywords"
)
'
然后创建两个具有唯一前缀的函数:
function unique_prefix_A() { }
function unique_prefix_B() { }
现在,当我输入unique_prefix_
并按下TAB
按键时,我并不期望看到任何内容,因为标签functions
已从 中删除tag-order
。
但是,由于Executables
、Builtins
、Commands
、Aliases
和没有提供任何补全,因此默认情况下将尝试匹配其他标签(即排除的标签),以尝试提供任何补全。 Variables
Keywords
zsh
functions
因此,将建议 以下功能unique_prefix_A
和:unique_prefix_B
我不喜欢这种行为并且想要将搜索限制在明确指定的标签内。
手册标签顺序风格表明了一个简单的解决方案:
- 如果任何值仅由连字符组成,则仅生成其他值中指定的标签。通常,如果指定的标签无法生成任何匹配项,则最后尝试所有未明确选择的标签。这意味着仅由单个连字符组成的单个值会关闭完成。
应用解决方案:
# Configure the order of tag matching as well as their descriptions.
zstyle -e ':completion:*:*:-command-:*:*' tag-order '
reply=(
"executables:Executables:Executables
builtins:Builtins:Builtins
commands:Commands:Commands
aliases:Aliases:Aliases
functions:Functions:Functions
parameters:Variables:Variables

当前行为是:
当我书写
c
并按下TAB
按键时,我会按正确的顺序获得适当的完成。)
当我书写
./
并按下TAB
按键时,我什么也没得到。
为什么现在只有executables
标签不起作用?
我该如何修复它并获得所需的行为?
答案1
在这种情况下,标签会调用。然后调用executable
更多,因此有必要指定这些_files -g '*(-*)
_files
_tags
完成函数中隐式指定的标签, 也。

在这种情况下,添加globbed-files
以下内容会很有用:directories
% ls -al
total 80
drwxr-xr-x 3 t t 4096 May 18 08:27 .
drwxrwxrwt 16 root root 69632 May 18 15:27 ..
drwxr-xr-x 2 t t 4096 May 18 08:27 directory
-rwxr-xr-x 1 t t 0 May 18 08:27 executable-file
-rw-r--r-- 1 t t 0 May 18 08:27 test
% ./<TAB>
Executables
directory/ executable-file*
但在上述设置中,目录和本地可执行文件将进入同一个“可执行”组。如果我们想让“目录”进入其他组,我们可以指定file-patterns
直接使用它像这样:
zstyle ':completion:*:*:-command-:*:*' file-patterns \
'*(#q-*):executables:Executables *(-/):directories:Directories'
zstyle -e ':completion:*:*:-command-:*:*' tag-order '
reply=(

aliases:Aliases:Aliases
functions:Functions:Functions
parameters:Variables:Variables

在下面的例子中,“目录”和“可执行文件”位于分开的组中:
% ls -al
total 80
drwxr-xr-x 3 t t 4096 May 18 08:27 .
drwxrwxrwt 15 root root 69632 May 18 15:24 ..
drwxr-xr-x 2 t t 4096 May 18 08:27 directory
-rwxr-xr-x 1 t t 0 May 18 08:27 executable-file
-rw-r--r-- 1 t t 0 May 18 08:27 test
% ./<TAB>
Executables
executable-file*
Directories
directory/
以下是最终的最小 .zshrc 示例:

zstyle ':completion:*:*:*:*:*' group-name ''
zstyle ':completion:*:descriptions' format '%B%F{black}%d%f%b'
zstyle ':completion:*:*:*:*:*' menu 'select'
