Mass cursor movement via Python
-
As I’ve pointed out in one or more previous posts, I’m a very amateurish user of the Python Script v2.1.0.0 plugin, with the majority of my simple scripts made up only of regex replacement sequences, but on rare occasions I need to do something requiring a little more sophistication. I’m currently investigating ways to move my cursor x number of spaces/words/lines at a time, such as moving it up 5 lines. I see, in the Python Script docs, that I can use
editor.lineUp()to move it up one line at a time, but of course am hoping for a way to move up all 5 lines in one go, so to speak, rather than having to repeat that line of code 5 times in my script. I figured a loop would be the most obvious solution, but my experience with them is pretty limited, so I consulted the PS docs further, as well as the NPP Community here, and our old sometimes-friend Google. I see multiple examples of simple, basic loops usingfor i in range(), which I tried as follows:for i in range(5) editor.lineUp()But the Python Script console outputs the following:
for i in range(5) ^ SyntaxError: invalid syntaxAm I doing something wrong?
Not that I’m inclined to trust any AI information, but when I googled
notepad++ pythonscript move caret one direction multiple times, Google’s AI Overview also suggests that I can just useeditor.lineUp(5). It only cost me less than a minute to give that a whirl, so what the heck, but I faired no better with it (issued via the console rather than a saved script). Console output:>>> editor.lineUp(5) Traceback (most recent call last): File "<console>", line 1, in <module> ArgumentError: Python argument types in Editor.lineUp(Editor, int) did not match C++ signature: lineUp(class NppPythonScript::ScintillaWrapper {lvalue})Full debug info:

Never mind on the use of
for i in range(), I see now that I neglected to put a colon after it. -
Instead of the
.lineUp()approach, I’d try finding the exact position you want to move the caret to, and then setting the current position to that.You’d need to find what column you’re in, what line you’re on, and then apply math and go from there.

Thanks for the suggestion, though I think
.lineUp()is sufficient for my purposes in this case, since I will need to repeatedly go up the same number of lines, and column isn’t a concern because I’ll always be landing on blank lines.
