Search in target is sometimes failing

Ekopalypse

yes, it could be that this is not the issue, but a new npp start also means that your data is not the same as before,
but you certainly have more information to evaluate this than I do,
I am fishing here more or less in the dark.
Can you describe in pseudocode what you are doing, maybe this could be helpful to find the issue.

Sure. This plugin just places a “\n” infront every case of “<” in the selected area.

function(){

Set the target search area to the area that has been selected.

Look for the first case of “<” in the targeted area.

While a, “<” can be found, get the placement of, “<”, insert a “\n” at that spot. Set the beginning of the target search area just ahead of where “<” is now found and increase the end of the target search area by 1. Search again for the next “<” in the target search area

}

From your explanation this doesn’t work.
You need to advance the start by 2, correct?
Assuming the following, 0123… are positions made visible.

0123456789
ab<def<h

position of < is 2 correct?
Insert c at that position results in

0123456789
abc<def<h

and if you set the start now to position+1 (=3) it will re-find the same <

Sure this is what you do?
My pseudocode would look like this

target = selected text
target_end = last position of selected text
position = search in target for '<'
while position > -1:
    insert char '\n' at position 
    reset target_start to position+2 and target_end to target_end+1
    position = search in target for '<'

Sorry, I am increasing the start by 2, I just didn’t clarify that. I meant that when I said, “Set the beginning of the target search area just ahead of where “<” is now found”. My mistake. I know my code works because when I select the text,

<<<<

it results in

<
<
<
<

Sorry for the confusion

Peter Goddard

@Ekopalypse Of course, my code works, until it breaks liked we talked about before

@Peter-Goddard

ok, then I would say it is time to debug/print some info about
target_start, target_end and position found.
Make a debug build, use OutputDebugStringW and tools like DebugView
to capture the output. Of course only, if you can’t run within Visual Studio.

Ekopalypse

Actually, it doesn’t have to be a debug build, a release build should do it as well.

Peter Goddard

@Ekopalypse

Okay, I’m trying that now. I am using visual studios and I have added in my code a OutputDebugStringW, now where would I find the values that it outputs when I use my plugin in notepad?

Ekopalypse

@Peter-Goddard

Did you start npp from within Visual Studio or did you attach (from Debug menu) npp to visual studio? If so, those should appear in
View->Output window.

I think I have made a very obvious mistake. I forgot to specify my search flag as you mentioned in my other post. After switching it to Regexp, it seems to be working. I feel like that was very obvious and you have taken a lot of your time to help me, so thank you again for all your help.

If anything else happens, I’ll post again. Thanks.
