zmv - 如果有多个连续的大写字母则不改变大小写

Question

我正在使用

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

改造

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

到

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

不过有个小问题

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

当前输出

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

mv -- FirstFolderToRename/DDDDDDD FirstFolderToRename/DDDDDDD
mv -- FirstFolderToRename/ThisIsDDDDD FirstFolderToRename/this-is-DDDDD
mv -- secondFolderToRename/DDDDDDD secondFolderToRename/DDDDDDD
mv -- secondFolderToRename/ThisIsDDDDD secondFolderToRename/this-is-DDDDD
mv -- DDDDDDD DDDDDDD
mv -- FirstFolderToRename first-folder-to-rename
mv -- secondFolderToRename second-folder-to-rename
mv -- ThisIsDDDDD this-is-DDDDD

Answer 1

指定 one or more upper case characters。那是 [[:upper:]]## 与 zsh 的扩展 globbing（zmv 使用）。 ## 类似于正则表达式 + 量词。单个 # 是 zero or more，类似于正则表达式 *.

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

可选地，单独转换前导大写字符，而不是之后删除首字母 -：

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

Answer 2

来自linuxquestions

function CamelOrPascalToKebab() {

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

}

zmv - 如果有多个连续的大写字母则不改变大小写

zmv - do not change case if there are more than one consecutive uppercase letters
