Modify indexes in python script using notepad++

问题

I have a Python script which reads data from a database into a list and fills a template. The database structure changed so now I have to add 2 to all indexes. Is there a way to do such thing using notepad++?

What I have is something like:

cursor.execute("SELECT * FROM mytable WHERE id = %s",id)
row = cursor.fetchone()
nameSpace = {'valone':str(row[1]),'valtwo':str(row[2]),'valthree':str(row[3]),} #and so on

And I need it to be:

cursor.execute("SELECT * FROM mytable WHERE id = %s",id)
row = cursor.fetchone()
nameSpace = {'valone':str(row[3]),'valtwo':str(row[4]),'valthree':str(row[5]),} #and so on

There's over a hundred variables, so I don't want to do it manually.

Thanks in advance ;)

You may use a simple regex like \w+\[([0-9]+)] and use a PythonScript to process these matches, incrementing the number inside Group 1.

Install PythonScript
Go to Plugins -> Python Script -> New Script
Create a new increment_numbers_2up.py script
Add this contents:

def increment_2_up(match):
    return '%s%s]'%(match.group(1), str(int(match.group(2))+2))

editor.rereplace(r'(\w+\[)([0-9]+)]', increment_2_up)

Now, run the script from Plugins -> Python Script -> Scripts -> increment_numbers_2up

I got this result: nameSpace = {'valone':str(row[3]),'valtwo':str(row[4]),'valthree':str(row[5]),} #and so on

Pattern details:

(\w+\[) - Group 1 capturing 1+ word chars ([a-zA-Z0-9_]) and a [
([0-9]+) - Group 2 capturing 1+ digits
] - a literal closing ] bracket.

The Python code here - str(int(match.group(2))+2) - parses the digits captured into Group 2 with int(match.group(2), then adds 2, and casts the value to a string with str().
