ChangeTxt v2.1 26/10/96
=======================
Overview
========
ChangeTxt converts text files between Acorn, PC and Macintosh platforms.
A registered version of ChangeTxt supports the following features:
- Line terminator mapping. i.e <CR> to <LF>, etc.
- Character set mapping between Acorn, DOS, OS/2 & Macintosh
platforms. So a bullet '•' will still look like a '•' even
if it has a different ASCII value between character sets.
- Strips invisible characters. Expands tabs.
- Provides direct conversions between platforms:
Acorn to Mac, Dos, OS/2
Dos to Acorn, Mac , OS/2
Mac to Acorn, DOS, OS/2
OS/2 to Mac, Acorn, DOS
- Guess platform type. ChangeTxt will examine the contents of a text
file and automatically choose a source platform to map to your
destination platform.
- Fully multitasking. All file conversions are performed in
background. Allows multiple files to be converted, even add files
with a different mapping during conversion.
- ArcWeb compatible. Automatically converts files downloaded from the
Internet.
An unregistered version only supports mapping between DOS and Acorn,
character set and line terminator mapping, multitasking and ArcWeb support.
For details on registration see the end of this file.
Using ChangeTxt
===============
To launch ChangeTxt, just double-click on the !ChangeTxt icon which will
then appear on the right hand side of the icon bar.
To view the ChangeTxt dialog click on the !ChangeTxt icon on the icon bar.
The ChangeTxt dialog is described below from the top of dialog down.
Conversions
============
Character set - if ticked, the source characters are mapped onto the
destination character set. e.g. • will map to •
Otherwise without character set mapping a • may map to ¢
Any character that cannot be mapped will be translated to
a ?
Termination - if ticked then the source format line terminators are converted to
the appropriate target format line terminators, otherwise no
conversion of the line terminators is performed;
Strip codes - if ticked then all control code characters are stripped from
the destination file. Control code characters are the
non-printable characters in the range of 0-31 ASCII, but
not including the destination format line terminators nor the
tab character;
Expand tabs - if ticked then any tab characters to be written to the destination
file are converted to a number of spaces as specified in the
spaces writable icon.
Below the conversion options are two pop-up menus separated by an arrow.
The pop-up menu to the left of the arrow is the source format. The pop-up
menu to the right of the arrow is the destination format.
The source and destination menus allow the user to specify one of the following
formats as either source or destination: Mac, DOS, Acorn, OS/2
Any mapping combination is allowed except to itself, so you will not be allowed
to map DOS to DOS.
The source menu has an additional item, Guess. When Guess is selected, ChangeTxt
will examine the contents of the source file in an attempt to identify the source
format. It will then convert the file to the selected destination format. As OS/2
and DOS text files are similar, any conflict on guessing will default to DOS.
Status
======
During conversion, the window displays the name of the file currently being
converted.
Below this a red bar shows the progress of the file being converted.
Below this a green bar shows the progress through a batch of files.
Drop files here
===============
To perform a conversion, drag the file to be converted onto the window.
A save dialog is presented which is used to give the destination path for
the converted file. If multiple files are dragged onto the window then a
destination directory is acquired. The converted file names are then the same
as the original file names, but placed in the given directory.
The conversion of the text files occurs in background. More files can be
selected for conversion while current conversions are taking place. ChangeTxt
remembers the conversion mapping associated with each file, so different jobs
can have different mappings.
Conversion can be aborted by clicking on the abort button in the window.
Aborting terminates all currently identified conversions. Abortion is
automatic if the window is closed or the program is quitted.
ArcWeb Support
==============
ChangeTxt can now be used alongside the ArcWeb browser to automatically convert foreign
text file formats to Acorn format before viewing. Conversion of the foreign file formats
is performed using the standard ChangeTxt dialog options. ChangeTxt can also be instructed
to terminate when ArcWeb terminates, so it can be placed in the WebHelper folder along with
the other helpers.
Icon Bar Menu
=============
Info -> displays the standard information dialog plus
registration details
Report -> displays the file conversion report window
Quit with ArcWeb -> if ticked then ChangeTxt will quit when ArcWeb quits
Save preferences -> saves the current dialog options and 'Quit with ArcWeb' state
to a 'prefs' file internal to ChangeTxt. These preferences are
automatically loaded when ChangeTxt is next started. Only
available if registered
Quit -> quits the ChangeTxt application
Dialog Menu
===========
The dialog menu contains a subset of the Icon Bar Menu options.
Limitations
===========
ChangeTxt has not been tested under RISC OS 2.
Registration
============
ChangeTxt uses a registration system which uses a key to enable full
functionality of the application. Without the key then ChangeTxt will
only allow a subset of its features to be used.
If you wish to register and use all of ChangeTxt's features then send
your name and address, along with a cheque for £10 (£30 for commercial users)
sterling to the address below.
In return we will send you a key which will enable all ChangeTxt's features.
The key belongs to you and will ensure that you will be able to fully use
any future versions of ChangeTxt.
As a registered user you may have any number of copies as your name
will appear in the program information dialog. You can also send us
a disc with your key for the latest version, which we will return to you.
