FEAT: Option Box to Treat Individual Line in Replace Dialogue as Independent searches

[rugabunda]

I am working with a hosts file A, which has 50 alphanumerically sorted entries I want, and 49,950 I don't want. I have hosts file B, which has only the 49,950 entries I don't want. I want to use the contents of file B to remove the contents from File A that I don't want. Currently this can only be done with regex S/R expressions. Currently I can search for one line at a time, and replace that no problem, but I can’t just as easily insert the entire hosts lists from file B and replace them all at once. It should be that simple imo. A simple check box to treat each individual contiguous line as its own search & replace in ascending order would be extremely valuable, and would save a lot of people a lot of time and searching around to find the proper expressions.

This problem has been already discussed many times ! So :

You have a first file, named File_A.txt, which contains a list of… whatever you like

You have a second file, named File_B.txt, which contains the same kind of list, with fewer lines than in File_A.txt

And you would like to delete, in File_A.txt, all the lines, which are, ALSO, present in File_B.txt

Wouldn’t you ?

Note that the following regex S/R compares complete lines, only !

Here is the method :

Start Notepad++

Copy/paste all contents of the main File_A.txt file in a new tab

At the end of this main list, add a new line of, at least 3 dashes ( --- )

now, append all contents of the File_B.txt file, AFTER this line

Open the Replace dialog ( Ctrl + H )

Select the Regular expression search mode

Tick the Wrap around option

SEARCH (?-s)^(.+\R)(?=((?s).+?\R)?\1)|(?s)^---.+

REPLACE Leave EMPTY

Click, once on the Replace button or several times on the Replace
Et voilà ! In the new N++ tab, any line, which was, both, present in the two files, has been deleted, as > > well as any possible duplicate lines, in the main File_A.txt file !

After performing the regex S/R :

SEARCH (?-s)^(.+\R)(?=((?s).+?\R)?\1)|(?s)^---.+

REPLACE Leave EMPTY

Here is a great example of where the simplicity of this would be extremely useful; taking multiple combined alphanumerically sorted lists, and organizing/separating them by file or by line/section! This is common practice. Having this functionality largely automated, as suggested above would be superb!
