Script to sort the current file

Requires sqlite3. If you have trouble with "import sqlite3" See:
  (Pertains to different packages but the issue is the same)
  May also be necessary to copy sqlite3.dll to:

  Sort the current file.
  Options are:
    Case sensitive y/n?     - Case sensitive sorting or ignore case
    Remove duplicates y/n?  - Remove duplicate lines from file
    Overwrite file y/n?     - Overwrite existing file or open a new one
    Right justify sort y/n? - Right justify data in the column for sort. Good for numeric data
    Column width            - Width of column to sort. Column starts at current caret position
import sqlite3
sSchema = 'CREATE TABLE sortLines (lineFrag TEXT {}, lineFull TEXT);'
sInsertStmt = 'INSERT INTO [sortLines] (lineFrag, lineFull) VALUES (:lineFrag, :lineFull)'
curPos = editor.getColumn(editor.getCurrentPos())
def sortLine(contents, lineNumber, totalLines):
    lineFrag = contents[curPos: curPos + searchLen].decode('latin-1')
    if rightJustify == 'y': lineFrag = (padding + lineFrag.rstrip())[-searchLen:]
    conn.execute(sInsertStmt, {'lineFrag':lineFrag, 'lineFull':contents.decode('latin-1') })
result = notepad.prompt('Case sensitive y/n?  Remove duplicates y/n?  Overwrite file y/n?  Right justify sort y/n?\nColumn width (number of characters to compare)', 'Sort File Options', 'nnnn25')
if result:
    caseSen = result[0:1].lower()
    removeDup = result[1:2].lower()
    overwriteFile = result[2:3].lower()
    rightJustify = result[3:4].lower()
    searchLen = result[4:]
    searchLen = int(searchLen) if searchLen.isdigit() else 25
    padding = ' ' * searchLen
    conn = sqlite3.connect(':memory:')
    conn.execute(sSchema.format('' if caseSen == 'y' else 'COLLATE NOCASE'))
    if overwriteFile == 'y':
    for row in conn.execute('SELECT {} lineFull FROM sortLines ORDER BY lineFrag'.format('DISTINCT' if removeDup == 'y' else '')):
