function to replace ASCII CR & LF chars eg by spaces

[ElectrONICs And SYStems]

Hello, notepad has a function to replace ASCII CR & LF codes eg by spaces?
ThankS

You can use the Regular Expression mode of Notepad++'s search-and-replace function:

Search > Replace (often mapped to Ctrl+H)

• Find What: “[\r\n]” => find either CR or LF
• Replace With: " " => Replace each CR or LF with a space
• Search Mode: ☑ Regular Expression

(the quotes are there to make the space obvious; don’t include the quotes)

However, that will cause windows-style EOL (CR+LF) to become two spaces
If you want a CR+LF to become one space, while still converting singleton CR or singleton LF to one space, change to

• Find What: “\r\n|[\r\n]” => find either CR+LF or CR or LF
  (keeping the other options the same)

Thanks

Some codes or characters are difficult to remember, then as a suggestion for notepad ++ developers, in the field search please add a table of characters for the purpose of easily paste them

You can also use the simpler “\R” to represent any of the various forms of line endings.

The idea from @ElectrONICs-And-SYStems is not bad. Before I had ultraedit and they have some kind of help in the search dialog to build regex:

Also the favorites in the search I used at that time a lot

When you not need the regex frequently then it is a nice hint to get back in the syntax.

@ElectrONICs-And-SYStems There is somewhat of a help for characters and codes in ASCII included with Notepad++. In the Edit menu, select Character Panel, and it will display the ASCII characters and codes.

@MaDill The Find/Replace dialog box does save some number of recent searches; however, it does not allow you to save favorites like the program you used appears to. I know there’s been some discussion on how many searches can be saved, and how to possibly increase that.

It’s not a bad suggestion, but some users posting here claim that each RegEx is generally unique. However, I for one, do like to have someplace to start when I create a RegEx. Currently, I use a text file with significant RegEx strings and descriptions of them. A limited number of “favourites” would be helpful.
