Notepad++ RegEx Only change last line in specific file

Question

The problem is i want to comment out a specific string in some files.

In most of them it looks like this

countries = {"GER","NZG",}

Replacing this is trivial. However there are some exception in which the string looks like this:

 countries = { "GER","NZG", }

I replaced the first line in the first run through by replacing "countries" with "--countries".

Now I found the next row with

^([\s][\"][A-Z]{3}[\"])

and Replaced it by

-- \1

Now my files look like this

 --countries = { -- "GER","NZG", }

I know this is not very efficent.

As you can see, I need to comment out the last "}". It is the last "}" in every file. But there are other single "}" in one rows.

These are lua files so maybe block commenting would be better. Still i don't know how to find the last "}" in the file.

Would be nice if someone could help me with that.

Sorry, i just added the recommended Tags. I thought this is more of a RegEx problem so ppl who know it from other programms might know an answare. — Binary

Ctrl+H
Find what: ^(\w+\h*=\h*\{)([^}]+)(\})
Replace with: --$1\n--\t$2\n--$3
check Wrap around
check Regular expression
Replace all

Explanation:

^ # begining of line ( # start group 1 \w+ # 1 or more word character \h* # 0 or more horizontal spaces = # equal sign \h* # 0 or more horizontal spaces \{ # opening curly brace ) # end group 1 ( # start group 2 [^}]+ # 1 or more non closing brace ) # end group 2 (\}) # group 3, a closing curly brace

Replacement:

--$1 # 2 hyphens and content of group 1 \n # linefeed, you may use \r\n for Windows --\t$2 # 2 hyphens, a tabulation, content of group 3 \n # linefeed --$3 # 2 hyphens and content of group 3

Result for given example:

--countries = { -- "GER","NZG", --}

Wow very nice. Okay this worked semi. It also found other strings which i solved by adding \bcountries\b to the first group instead of \w+. I also changed the replace with --[[ $1 \n \t$2 \n $3 ]] (for block commenting) Also thank you for the explanation what all those expressions mean. My last try to find those strings looked like this xD ^([\s]?\bcountries\b[\s][\=][\s][\{][\s]?){1} ([\s]?([\"][A-Z]{3}[\"])+[\s]?[\,]*)+([\s]?[\}]) — Binary

@Binary: You don't need to use character class for a single character, [\s] is better written \s, [\"] ==> ", [\=] ==> =, {1} is superfluous as \b between \s and countries If you want to only match countries, use (\bcountries\h*=\h*\{)([^}]+)(\}) — Toto
