====================
  Why this plugin?
====================

I'm a Delphi developer and beyond writing code I'm responsible for
our company's build system which is based on old-school batch
scripts. For changing and extending these scripts I use Notepad++.

One day I made some changes and after that we had a malfunction in
the build system caused by a typo related to the wrong encoding of
german umlaut characters - when editing the batch script I forgot
to set the correct character encoding, OEM 850 in this case.

To secure the process of editing our build scripts I wrote this
plugin to automate the encoding switching. Maybe some other batch
scripters will find it useful too.

To get as much flexibility as possible I made it configurable so
that one can use it not only for batch scripts on a german Windows
installation.



============
  Features
============

This plugin allows you to create file classes which are defined by
the related filename extensions and (optionally) a language (s.a.
menu "Languages" in Notepad++). For every file class you have to
provide the code page to which should be switched to when the
plugin detects that the active Notepad++ document is a member of
this file class.

The plugin captures the following events in Notepad++:

  - The active tab of Notepad++ is changed.

  - The language of a file already loaded in Notepad++ is changed.

  - The file extension of a file already loaded in Notepad++ is
    changed.

  - A file is saved, closed or deleted (only for internal
    management).

When one of these events fires the plugin gets invoked. After it
has verified the membership to a certain file class it changes the
code page of the active document to the related code page of its
file class, according to your settings.

NOTE: AutoCodepage only helps you to work with already existing
documents. The encoding of documents newly created in Notepad++
has to be set by the user BEFORE writing content.



=================
  Installation
=================

1. If you run a 32 bits version of Notepad++ copy the file
   "bin\x86\AutoCodepage.dll" to the directory
   "plugins\AutoCodepage" of your Notepad++ installation.
   In case of a 64 bits version take the file
   "bin\x64\AutoCodepage.dll". You can find the "plugins"
   directory under the installation path of Notepad++. The
   directory "AutoCodepage" you have to create by yourself.

2. Copy the file "doc\AutoCodepage.txt" to the directory
   "plugins\AutoCodepage\doc". If it doesn't exist create it.
