Replace line end symbols?

vanowm

Is there a way replace line end symbols?
Currently CR/LF symbols are very large and distracting:

I’d like make look like in UEStudio:

Thank you.

Not a reasonable way (NPP is open source so you could probably develop a way if you are a programmer).
I am quite sure that these symbols come from Scintilla so you should check out there.
Or just use UEStudio.

They are Scintilla representations and there are Scintilla commands to change them, but I have not been able to find a simple way to make changes persist across files and tabs.

Scintilla is embedded in Notepad++ and the default representations are easy to find in the .exe with a hex editor. They are two and three character representations, which makes them distracting. I editted a few that I use a lot - “NUL” "LF “CR” and “ESC” to “0” “n” "r and “e” - and that makes them permanent.

Highlight above is from LF to CR / “n” to “r” They are still shown with a reverse background, but only one character wide.

Of course, you’d have to do the edit again for each Notepad++ update.

Now THAT is an ambitious approach to solving the problem! :-)

Seems like there should be a way to use SCI_SETREPRESENTATION with NppExec or PythonScript to do this?

Cheers.

Yes, it can be done, with the complication that it has to be done on every tab switch, because N++ “resets” this aspect of Scintilla when the active document changes. IMO it is better than hacking the exe.

All,

For most characters, re-asserting at every tab switch is sufficient.

However, in my experience, setRepresentation doesn’t work as expected for the CR and LF characters… when I tried editor.setRepresentation("\r", "x"), it gives

– it shrinks the box width down to 1 character rather than two, but still tries to say CR instead of x. Similarly, a longer replacement like carriage return allocates enough space for the extras, but still uses the CR text.

(the results on \n for LF are similarly ineffective and unhelpful)

I had this exact same behavior attempting to do this from LuaScript as well (thought it was a bug in the plugin). Setting it for some other character such as "h" worked but not "\r" or "\n"

Newer versions of Scintilla have better support for line end representations. A snippet from the changelog of Scintilla v5.1

Add APIs for setting appearance (traditional blob or plain text) and colour of representations and support setting a representation for the “\r\n” line end sequence.

… another reason to hope that Don and team are working toward the newer Scintilla in the not-too-distant future. :-)
