Hey I have to change in a lot of places camelCase to snail_case.
I have following example:
billingAddress
paymentDetails
I tried to use find and replace with regex in PhpStorm
In 'find' input field I put in:
([A-Z])
In 'replace' input field I put in:
_\L$1
Result I got:
billing_LAddress
payment_LDetails
What do I need to change in order to get following result:
billing_address
payment_details
First open Find and Replace functionality with
CTRL
+R
and then check the boxesMatch Case
andRegex
(and if necessaryIn Selection
):1. To replace camelCase to snail_case as in in the question:
find:
([A-Z])
replace:
_\l$1
someThing -> some_thing
2. To replace UPPERCASE words to lowercase words use
\L
find:
(\w*)
replace:
\L$1
SOMETHING -> something
3. To replace lowercase words to UPPERCASE words use
\U
find:
(\w*)
replace:
\U$1
something -> SOMETHING
4. To replace first character of words with lowercase use
\l
find:
(\w*)
replace:
\l$1
Something -> something
5. To replace first character of words with UPPERCASE use
\u
find:
(\w*)
replace:
\u$1
something -> Something
Note: Add some extra boundaries
You get best results by adding some additional boundaries that suit your specific case, for example single
'
or double quotes"
or line breaks\n
