Basics

What is TextPipe?

TextPipe is a powerful text transformation workbench that performs an enormous range of conversions and manipulations to text files. It is unique in the number of transformations that can be performed at one time, in the power and flexibility of its transformations, in the size of files it can handle and more. Data can be extracted from databases in a variety of text formats, and custom transformations can be written in VBScript, JScript and other scripting languages.

Opening TextPipe

If you haven't already started TextPipe, start it now by

• Double-clicking on the TextPipe icon on the desktop OR
• Clicking on TextPipe in the Start Menu\Programs\TextPipe folder
• TextPipe starts with a new filter list (you may have to click Ok to clear the About dialog in the evaluation version, and close the Tip Of The Day and Filter Wizard dialogs).

The TextPipe Screen

At the very top of the TextPipe window is the Title Bar. The Title Bar tells you which filter list you are working on and whether it has been modified or not. Below the Title Bar is the Menu Bar, with the customary File, Edit, Window and Help menus, along with a Filter menu that categorize text processing filters into functional groups (we'll come back to filters in a minute).

Below the Menu Bar is the Tool Bar. The Tool Bar has icons for the most commonly used features of TextPipe, such as saving and loading filter list files, cutting and pasting and so on. The Tool Bar saves you having to navigate through the menus. If you hover the mouse cursor over a Tool Bar icon for a second, a hint will be displayed beside the mouse cursor that describes what the icon is for. At the same time, a helpful message will be displayed in the Status Bar at the base of TextPipe's window. You should watch for helpful text in the Status Bar whenever the mouse cursor is over a field in TextPipe's window, because the Status Bar always has extra information for you.

The Tab Bar is below the Tool Bar, and it contains a group of tabs that divide up the main tasks within TextPipe. We'll cover it in more detail below.

What is a filter list?

A TextPipe filter list consists of:

• A list of operations to perform (filters)
• A list of files that will be processed
• (Optionally) Trial text that can be used to test the filter list.
• To understand this more fully, we'll open a sample filter.

Opening (loading) a filter list

• On the File Menu, click Open
• The Open Filter List window appears
• Double click on the Tutorial folder (if you can't find it, it's usually in C:\Program files\TextPipe\Tutorial). Note - you can load any filter from the subject area subfolders such as coding, conversions, email, etext, fun, html, sysadmin or vbscript
• Double click on 'lesson1'
• TextPipe opens the lesson1 filter list.
• The default tab is the Filters to Apply tab. It shows which filters will be performed, and in what order. Order is very important! In our lesson1 filter list, the only filter we will use is a straight-forward search and replace filter, which replaces capital T with lowercase T. We will cover the File Input and File Output filters later.

Click on the Files to Process tab. Although currently empty, this is where we list all the files that should be processed.

Click on the Trial Run tab. The Trial Run Input area already has some sample text. When we test the filter with a Trial Run, the Trial Run output appears on the right hand side so that we can compare the output with the original, and make sure that the filter works as we expect. This can be really handy for complex filters.

Click the Trial Run button at the base of TextPipe's window. Some new text appears on the right hand side - with all capital T's replaced with lowercase t's (3 in all). This is exactly what we expect - because we have a single filter that is called Replace [T] with [t].

Add the text 'This is my line of text.' to the end of the text in the Trial Input area, and click the Trial Run button again. The new output text is shown.

Click the Trial Run button again. TextPipe toggles between the Filters to Apply tab and the Trial Run tab each time you click this button, although if you've changed the Trial Input text (as we just did), it will re-process the text and display the output in the Trial Run Output area without toggling.

Saving a filter list

If you want to save the filter list:

1. On the File Menu, click Save.

If you want to save the filter list with a new name:

1. On the File Menu, click Save As
2. The Save Filter List window appears
3. Type in a new name
4. Click the Save button.
