append an existing string with notepad-CodePudding

I have multiple text files opened in Notepad . And each file is like this.

[11]
[205]
[77]

I'm searching for [[0-9] ]\s in regex mode, but I don't know how to replace it to the output I need.

And I want to append a string like this in all opened files, like this.

[11.0]
[205.0]
[77.0]

I'm searching for \[[0-9] \]\s in regex mode, but I don't know how to replace it to the output I need.

How to do this?

CodePudding user response：

Ctrl H
Find what: \[\d \K(?=])
Replace with: .0
CHECK Wrap around
CHECK Regular expression
Replace all

Explanation:

\[      # openning squarre bracket
\d      # 1 or more digits
\K      # forget all we have seen until this position
(?=])   # positive lookahead, make sure we have a closing squarre bracket after

Use this regex for searching:

(\[\d )(\])

and the following for replacing:

\1.0\2

You need to escape [ and ] in your pattern via a \ since they have a special meaning in the regular expression world.
