Converts a string to kebab case.
|
|
|
|
- Use `re.sub()` to replace any `-` or `_` with a space, using the regexp `r"(_|-)+"`.
|
|
- Use `re.sub()` to match all words in the string, `str.lower()` to lowercase them.
|
|
- Finally, use `str.join()` to combine all word using `-` as the separator.
|
|
|
|
```py
|
|
from re import sub
|
|
|
|
def kebab(s):
|
|
return '-'.join(
|
|
sub(r"(\s|_|-)+"," ",
|
|
sub(r"[A-Z]{2,}(?=[A-Z][a-z]+[0-9]*|\b)|[A-Z]?[a-z]+[0-9]*|[A-Z]|[0-9]+",
|
|
lambda mo: ' ' + mo.group(0).lower(), s)).split())
|
|
```
|
|
|
|
```py
|
|
kebab('camelCase') # 'camel-case'
|
|
kebab('some text') # 'some-text'
|
|
kebab('some-mixed_string With spaces_underscores-and-hyphens')
|
|
# 'some-mixed-string-with-spaces-underscores-and-hyphens'
|
|
kebab('AllThe-small Things') # 'all-the-small-things'
|
|
```
