zmv-如果有多个连续的大写字母，请不要更改大小写

Question

我正在使用以下命令

zmv -n -Q '(**/)(*[[:upper:]]*)(/)' '${1}${(L)${2//(#b)([[:upper:]])/-$match[1]}#-}'

转换

% tree
.
├── EmptyFile.txt
├── FirstDirectoryName
│   ├── FourthDirectoryName
│   ├── secondDirectoryName
│   └── thirdDirectoryName
├── FourthDirectoryName
├── secondDirectoryName
└── thirdDirectoryName

至

% tree
.
├── EmptyFile.txt
├── first-directory-name
│   ├── fourth-directory-name
│   ├── second-directory-name
│   └── third-directory-name
├── fourth-directory-name
├── second-directory-name
└── third-directory-name

然而，有一个小问题。

如果有多个连续的大写字母，我不想小写。我只想把-放在大写字母后面，因为它不在开头。

% tree
.
├── DDDDDDD
├── FirstFolderToRename
│   ├── DDDDDDD
│   └── ThisIsDDDDD
├── secondFolderToRename
│   ├── DDDDDDD
│   └── ThisIsDDDDD
└── ThisIsDDDDD

电流输出

% zmv -n -Q '(**/)(*[[:upper:]]*)(/)' '${1}${(L)${2//(#b)([[:upper:]])/-$match[1]}#-}'
mv -- FirstFolderToRename/DDDDDDD FirstFolderToRename/d-d-d-d-d-d-d

mv -- FirstFolderToRename first-folder-to-rename
mv -- secondFolderToRename second-folder-to-rename
mv -- ThisIsDDDDD this-is-d-d-d-d-d

预期输出

Answer 1

指定one or more upper case characters。这就是具有zsh的扩展globbing(zmv使用(的[[:upper:]]##。##类似于正则表达式+的量词。单个#是zero or more，类似于正则表达式*。

zmv -n -Q '(**/)(*[[:upper:]]*)(/)' '${1}${(L)${2//(#b)([[:upper:]]##)/-$match[1]}#-}'

可选地，单独转换前导大写字符，而不是在之后删除初始-：

${1}${(LM)2##[[:upper:]]#}${(L)${2##[[:upper:]]#}//(#b)([[:upper:]]##)/-$match[1]}

来自linuxquestions

function CamelOrPascalToKebab() {
zmv -Q '(**/)(*[A-Z]*)(/)' '$1${2//(#b)([a-z])([A-Z])/$match[1]-$match[2]}'
zmv -Q '(**/)(*[A-Z][a-z]*)(/)' '$1${2//(#m)[A-Z][a-z]/${(L)MATCH}}'
}
