Notepad++ Python Script - Find files containing string at specific line

toxpal

@Scott-Sumner thanks for your suggestions. I will check editor.getTextlength(), but searching with regex won’t suit my needs, because I only need to find files that contain closing PHP tag at exactly next-to-last line and ignore all the files that contain such a tag in other line(s).

I fail to see how a regex in the call to editor.findText() or editor.research() can’t help solve your problem.

Okay, so we can tighten up the regex (which means making it longer, ironically) to match your description better:
(?s)<\?php\r\n.+?\?>\r\n[^\r\n]+(?:\r\n)?\z

…but that doesn’t help aid my understanding of why you think it can’t benefit your situation.

I’ll give it a try, and let you know how it works.

Tried using regex, but script does nothing (not sure if it’s regex or script’s fault):

import os;
import sys;
filePathSrc="C:\\Temp\\some_directory"
for root, dirs, files in os.walk(filePathSrc):
    for fn in files:
      if fn[-4:] == '.php':
        notepad.open(root + "\\" + fn)
        textlength=editor.getTextlength()
        editor.findText('SCFIND_REGEXP', 0, textlength, '(?s)<\?php\r\n.+?\?>\r\n[^\r\n]+(?:\r\n)?\z')

Update: pretty sure it’s scripts fault because even if I write such a simple search function, it does NOT work:

import os;
import sys;
filePathSrc="C:\\Temp\\some_directory"
for root, dirs, files in os.walk(filePathSrc):
    for fn in files:
      if fn[-4:] == '.php':
        notepad.open(root + "\\" + fn)
        textlength=editor.getTextlength()
        editor.findText('SCFIND_WHOLEWORD', 0, textlength, '<html>')

What am I missing here?

Perhaps “<” and “>” are not considered parts of a word, so SCIFIND_WHOLEWORD fails given your “word”?

Maybe try SCIFIND_REGEXP with a regex having no special characters (like “html”) to find out?

toxpal

Tried:

import os;
import sys;
filePathSrc="C:\\Temp\\some_directory"
for root, dirs, files in os.walk(filePathSrc):
    for fn in files:
      if fn[-4:] == '.php':
        notepad.open(root + "\\" + fn)
        textlength=editor.getTextlength()
        editor.findText('SCFIND_REGEXP', 0, textlength, 'html')

Also does nothing…

As my second point in my first post in this thread, I pointed out that the first argument to the editor.findText() function is NOT a string. Continuing to code it as if it is a string will get you nowhere. I think that if you look at the Pythonscript console window after running the script you will see that your script isn’t doing “nothing”, it’s giving you errors. For me it gives this error when I (intentionally) specify a string as the first argument to editor.findText():

f = editor.findText('SCFIND_REGEXP', 0, editor.getTextLength(), 't')
<class 'Boost.Python.ArgumentError'>:  Python argument types in
Editor.findText(Editor, str, int, int, str)
did not match C++ signature:
findText(class NppPythonScript::ScintillaWrapper {lvalue}, int flags, int start, int end, class boost::python::api::object ft)

The complete set of proper values for the first argument is found in the help docs for Pythonscript:

class FINDOPTION :
FINDOPTION.WHOLEWORD 
FINDOPTION.MATCHCASE 
FINDOPTION.WORDSTART 
FINDOPTION.REGEXP 
FINDOPTION.POSIX

Thank you for your efforts. I’m totally new to Python, so I’m having troubles with it.

So I modified script:

import os;
import sys;
filePathSrc="C:\\Temp\\some_directory"
for root, dirs, files in os.walk(filePathSrc):
    for fn in files:
      if fn[-4:] == '.php':
        notepad.open(root + "\\" + fn)
        console.write(root + "\\" + fn + "\r\n")
        end_position=editor.getTextlength()
        editor.findText(FINDOPTION.MATCHCASE, 0, end_position, "<html>")

Now console returns error AttributeError: 'Editor' object has no attribute 'getTextlength'

Changing getTextlength to getLength removes all the errors in console, and it only displays a message that PHP file was opened. However, it still doesn’t find any string

OK, so you have to read the documentation to see how these “editor” functions work. See Plugins -> Pythonscript -> Context-Help.

If you do this, you will see that editor.findText() returns a value indicating where a match did (or didn’t) occur.

Does this make sense?

Same thing applies to editor.getTextLength()…except in that case you actually have to spell it correctly (hint: case matters)…
