@guy038 The testing looks better. If the Change History -> Show in text option is checked then can see changes to a character for more detail. No need to retest and repost images to show the indicators. A change of the regex pattern to: Find: (?-s)^(?=.{79}).{1,78}\K\x20(?!\R) Replace: \r\n and then press the Replace All button. It does replace less as it does not capture and so only the \x20 space is matched. Unfortunately, it will read the line to length of 79 and then read the line again if line is 79 to continue the pattern so might be slower then your previous tested pattern. The (?=.{79}) is needed to ensure shorter lines are not matched for wrapping. The (?!\R) is probably optional to have in the pattern as it is limited to detecting trailing spaces. Since the pattern uses \K, then the Replace button is not expected to function properly to step through the replacements. The text comparison in my testing shows the regex patterns achieve equal results which seems to be fortunate. That test was done on license.txt.

@vivek-viv , Unfortunately, there are an unknown number of “programming languages” or “data file languages” in the world, and no text editor can syntax-highlight 100% of them out-of-the box. Apex is not available in the syntax-highlighter library that Notepad++ uses, and until it is, it will never be in the upper portion of the Language list. To get it added: A feature request would have to be put into Lexilla, and then the Lexilla team, or external volunteer, would have to code up that lexer, and they would have to accept it, bundle it with the library; then Notepad++ could update to use a version with that, and then and only then, Notepad++ could be updated to enable and list the Apex language in the default menu. I’m not saying it’s impossible… just that it’s not likely to be fast. If Apex were similar enough to another language, then, in theory, the Apex language could be mapped to use the that existing language’s lexer, but given its own list of keywords. However, Notepad++ has the User Defined Language (“UDL”) feature, which allows you to define a keyword-based syntax highlighting – so you can put in various lists of keywords, operators, folding-keywords, and delimiter pairs, and get it to do a reasonable job of highlighting simple syntax in your language. The User Defined Language page, and all the UDL > pages in the manual’s table of contents below it, describe how to use the UDL system. There’s also a community-contributed User Defined Language Collection, where people can share UDL definitions that they’ve made, or find ones to use for themselves. I don’t see Apex there… but if you created one, you could share it there, so that other Apex users I did a quick search, and if this is the Apex you are talking about, then it looks similar to YAML (builtin) – so maybe trying to use the YAML lexer might be an initial workaround. And google search AI tells me that the HAML uses a similar structure – there is a UDL in the Collection for HAML, so you might be able to use that as a reference for how to get something like what you want for Apex. No guarantees, but it’s a starting point…

Hello, @thomas-knoefel and All, Indeed, changing the line : LoadThreads="auto" into this one : LoadThreads=0 within the MultiReplace.ini file, the same list of files were found in 2 m ( instead of 1 m 13 s ) Thus, I decided of an experiment, changing, on purpose, the LoadThreads line to : LoadThreads=8 After restarting my computer and doing the test, the execution time was, this time, 1 m 28 s. However, verifying within the MultiReplace.ini file, I saw the line : LoadThreads="0" Is this the expected behavior, with the number 0 as a string ? Best Regards, guy038
