Setting preferences for comparing files

When you select to compare or synchronize two or more resources in the Workbench, one or more comparison editors usually open. To customize how these editors behave:

  1. Open the command link General > Compare/Patch preference page.
  2. Set your preferences and click OK.

You can configure the following options on the General tab.

Option

Description

Default

Open structure compare automatically

Makes an additional information area visible which shows differences in the underlying structure of the resources being compared. This information may not be available for all comparisons.

On

Show structure compare in Outline view when possible

If this option is on, structure compare will be displayed in the Outline view whenever it is possible.

Off

Ignore white space

Causes the comparison to ignore differences which are whitespace characters (spaces, tabs, etc.). Also causes differences in line terminators ( LF versus CRLF) to be ignored.

Off

Automatically save dirty editors before patching

This option controls whether any unsaved changes are automatically saved before a patch is applied.

Off

You can configure the following options in the Text Compare tab.

Option

Description

Default

Synchronize scrolling between panes in compare viewers

The two compare viewers will "lock scroll" along with one another in order to keep identical and corresponding portions of the code in each pane side by side.

On

Initially show ancestor pane

Sometimes you may want to compare two versions of a resource with the previous version from which they were both derived. This is called their common ancestor, and it appears in its own comparison pane during a three way comparison.

Off

Show pseudo conflicts

Displays conflicts that occur when two developers make the same change, for example when both add or remove the same line of code.

Off

Connect ranges with single line

Controls whether differing ranges are visually connected by a single line or a range delimited by two lines.

On

Highlight individual changes

Controls whether the individual changes inside conflicts are highlighted .

On

Disable capping when comparing large documents

The capping mechanism is used to speed up finding differences in large files. In case where the capping happens the result can either be correct or it can display too many changes, but it never misses any change. Turn this option on, if you prefer a precise result in favour of possibly longer calculation time.

Off

Swap left and right

Allows to swap the left and right side of the compare panes.

Off

When the end/beginning is reached while navigating an element

Use this option to configure what occurs when the end/beginning is reached while navigating an element. The options are:

  • Prompt
  • Go to the beginning/end of the element
  • Display the next/previous element
  • Do nothing
