Comparing Sources

When comparing source between different Visual DataFlex versions it is a HUGE time saver to do this using source code compare tools. Below is a few rules one can use to compare sources between VDF11.1 and VDF12.1

The tips below are for a product called Beyond Compare, but i'm sure your product will do fine too. If you are not using a product for this then GO BUY ONE! it is the best investment you can make EVER.

In order to change the rules on how BC compares, you should go into compare source mode and then click on the "guy with the cap" in the toolbar

General Tab Page

Name : DataFlex Associated with: .src;*.pkg;*.dg;*.vw;*.dd;*.sl;*.ddo;*.rv;*.tt?;*.wo;*.utl;*.nui

Whitespace includes TABS and spaces

Importance Tab Page

Unimportant text, put a check in all of the checkboxes

This is also the place where you can add custom rules.

1. Ignore differences in comments.

Click on New, Category Delimited
Beginning with: //
Check "stopping at end of line"

2. Ignore new metadata markup

Click on New, Category Delimited
Beginning with: {
and ending with: }

3. Ignore "current_object" vs "self" syntax
