How to lowercase selected text using a Replace RegEx in Notepad++ - regex

I'm looking for a way to lowercase selected BACKTICKED text using a regex in Notepad++
Here's an example string:
Select * FROM `Weird_TEXT` WHERE
And the desired output:
Select * FROM `weird_text` WHERE
I can find these strings (including the backticks) using the regex:
(?<=FROM )(.*)(?= WHERE)
`Weird_TEXT`
But I can't figure out how to replace the text as lowercase, I've tried using the following:
\1\L\2\L
\1\L\2\L\3
EDIT:
When I click Find Next in Notepad++, the backticks around the word Weird_TEXT are included in the selection. Could this be why the RegEx isn't working?

Just put this in the replace box:
\L$1

Regex Transform or Text Replace in Text Editor

I am trying to do an advanced text search and replace in a text editor (I can use SublimeText or VSCode)
Input:
parameters['myParameter1']
parameters['myParameter2']
Expected output:
myParameter1
myParameter2
And I have hundreds of similar scenario in the file. So that's why I'm thinking of using regex to solve this.
Thanks
Hope this will help you out.
Regex demo
Regex search: parameters\['([^']+)'\]
1. parameters\[' this will match parameters[' Optinally if you have other keywords then parameters and which can be dynamic for that you can use [a-zA-Z]+ this will include all lower case and upper case.
2. ([^']+) this will match all except ', () will capture first match in $1.
3. '\] this will match ending ']
Replacement: $1
Note: If you are using gedit ubuntu you have to replace it with \1
VSCode can search all files in a directory, and it supports RegExp too!
Use ctrl+shift+f to search all files, hit the .* icon for RegExp.
A search expression such as parameters['(.*)'] replaced with $1 should work!

Sublime text find and replace with special characters

I suck at regular expressions and what to do a simple find and replace of '}' to '} /n' notepad++ can recongise what I'm after as it has the 3 options of normal find and replace, special chars and full regex. I however only ever used to option two. How can I enable special characters in my search using sublime text 2.
Cheers
Joe,
In sublime you can use find & replace. Drag the replace panel large enough and use cmd + enter to go to a new line.
Hit replace all:
And thats it your sorted chap
If you want to replace } within notepad++ with } \n you can use the following rules:
find: }
Replace with: } \n
Searchmethod: Extended (\n, \e...)
Press replace all

Regex to convert CamelCase identifiers to UPPER_CASE

I have following lines
GetAuthServerList
GetAuthServerConfiguration
AddAuthServer
I have to convert them to
GET_AUTH_SERVER_LIST
GET_AUTH_SERVER_CONFIGURATION
and so on.
I tried to replace ([A-Z][a-z]+) with \1_ in sublime text editor, but it is replacing the last search also. How do I skip the last match of the line?
Can I simultaneously insert _ and make the lower case to uppercase in one replacement?
Find what : ([a-z])([A-Z])
Replace with: \1_\2
You have an option to convert selection to uppercase in sublime text.
I don't have sublime installed, but try this:
[a-z](?=[A-Z])
replace it with &_
or
replace ([a-z])(?=[A-Z]) with \1_
in vim it would be:
%s/\v[a-z]([A-Z])#=/&_/g
A little modification using negative lookahead should help
([A-Z][a-z]+)(?!$)

Sublime Text 2 RegEx replace n with n+1

Using RegEx search and replace with Sublime Text 2, how can I replace my pattern matches (n) with n+1? And if there is no way to do this with search and replace, is there another easy way to do it?
My RegEx pattern is ^(\d{1,4})\n, and I'd like to be able to do $1+1, which currently just outputs the match with a literal "+1".
Regex is the wrong tool for that function. However, there is Sublime Text plugin just to do what you want: "Sublime Text plugin to increment/decrement all selected numbers"
