Converts a string to snake case.
|
|
|
|
Break the string into words and combine them adding underscore `_` as a separator, using a regexp.
|
|
|
|
```py
|
|
import re
|
|
|
|
def snake(str):
|
|
return '_'.join(re.sub('([A-Z][a-z]+)', r' \1',
|
|
re.sub('([A-Z]+)', r' \1', str)).split()).lower()
|
|
```
|
|
|
|
```py
|
|
snake('camelCase'); # 'camel-case'
|
|
snake('some text'); # 'some-text'
|
|
snake('some-mixed_string With spaces_underscores-and-hyphens'); # 'some-mixed-string-with-spaces-underscores-and-hyphens'
|
|
snake('AllThe-small Things'); # "all-the-smal-things"
|
|
```
