Improvements to Merge in the next ExamDiff Pro

In the next ExamDiff Pro we will be making a variety of improvements to three-way diff and merge, including the ability to diff without merging, more ignore options, and general improvements to merge performance.

Three-Way Diff Without Merge

One of the new features coming to merge in ExamDiff Pro is the ability to use the three-way diff feature without having to merge to an output file. This can be done by checking the Diff Only checkbox in the comparison dialog, as shown below.

The result of using this option can be seen as follows:

Additional Ignore Options

Another new merge feature is the addition of several new advanced ignore options. These options have existed in 2-way diff for a long time and they can now be used in three-way diff and merge as well. These include case ignore settings and options to ignore parts of lines. These new options can be seen below, in the Text Merge section of the Options dialog.

Below we see the results of having entered "outcome|result" in the Parts matching regular expression text box. As seen below, on lines 8-9-7, the difference between the two lines is ignored as the only difference is the use of the words "outcome" and "result".

Improved Performance

In addition to the above features, several general improvements have been made to the performance of three-way diff and merge operations.

Improved Icon Size Customization and High DPI Display Support in the next ExamDiff Pro

In the next edition of ExamDiff Pro we will be introducing two new icon sizes, 32x32 pixels and 48x48 pixels, in addition to the previous 16x16 and 24x24 icons.

Along with introducing new size options for our icons, we have updated many of our older icons that have been around since the earliest editions of ExamDiff Pro. Users can change the sizes of icon sizes for toolbars and menus separately in the Customize menu as seen below.

Below, you can see what the new UI of ExamDiff Pro 9.0 will look like with the new icons set to 32x32 for toolbars and 24x24 for menus. Note that the Options menus use the menu icon size for the options trees and lists.

For comparison, below is the old UI and icons at 24x24.

In addition to giving the user the ability to set the size of icons in toolbars and menus, ExamDiff Pro 9.0 will automatically scale button icons to adapt to users with high DPI display.

Fast Binary Comparison Mode (Byte-By-Byte Comparison) in the next ExamDiff Pro

In the next version of ExamDiff Pro we will be introducing fast binary comparison mode (byte-by-byte comparison). This feature can be turned on in the Options menu, under Binary Compare.

When activated, ExamDiff Pro will simply compare each byte of one file with the corresponding byte of another file, rather than executing the diff algorithm. As such, there will be no offsets for matching blocks of bytes and ExamDiff Pro will only detect changed, rather than added or deleted blocks (except for the last blocks of files - if they have different sizes). As can be seen below, byte-by-byte comparison also shows the hex memory addresses of each row of bytes.

A similar comparison with byte-by-byte disabled is shown below.

Running binary comparisons with fast binary comparison mode will also be much faster and use significantly less memory.

Logging in the next ExamDiff Pro

The next version of ExamDiff Pro will introduce logging of actions, errors, results, and other messages. By default, ExamDiff Pro will output the log to the Output Pane at the bottom of the ExamDiff Pro comparison window. This pane is shown below.

As discussed in the previous blog on the updated UI in ExamDiff Pro 9.0, this pane can be adjusted to show it permanently, hide automatically, hide permanently, or floating.

Each of the colors is used to identify a different type of message. Black indicates Results, blue indicates Action, green indicates Message, and red indicates Error.

Additionally, as shown below, right-clicking in the Output Pane shows a context menu that lets you Copy some text, Clear the current output log, Select All the text in the output log, or enable Word Wrap for particularly long strings in the Output Pane.

Users can also change the way ExamDiff Pro handles logging through the Options dialog, that can be reached by navigating to Tools | Options and then selecting Logging under Global.

In the Logging options, the user can choose to Log to file, which will output the actions log to a file in addition to the Output Pane.

There is also an option to either Append or Overwrite the log with each new instance of ExamDiff Pro. Selecting Append results in new records being appended to the bottom of the previous log file, while Overwrite will replace the file created in previous sessions.

The File size limit options allows you to prevent the log file from growing past a user selected limit. If a log file exceeds the limit, a new log file will be created and the old file will be renamed with a timestamp.

Lastly, the Include process ID will include ExamDiff Pro process ID with each line in the log file.

Forced Binary Comparison and Option Profiles in DiffNow

We are excited to announce the addition of two new features for Premium users of DiffNow!

Force Binary Comparison

The ability to force the binary comparison of files in DiffNow has been a much requested feature for a long time. In the latest update of DiffNow, Premium users will be able to select the Force binary comparison checkbox in the Compare options tab to enable this feature.

Enabling this option will disable any pre-processing plugins and automatically compare files as binaries. For example, normally comparing Microsoft Word DOC files in DiffNow will first convert the contents to plain-text and then compare. Comparing DOC files with Force binary comparison checked will skip the conversion and compare them as binary files, as seen below.

Option Profiles

Many advanced DiffNow users have requested the ability to save multiple sets of options for different use cases. With the new update to DiffNow, users of DiffNow Premium will be able to make an unlimited number of option profiles.

Users can create profiles by simply pressing the Save As button and entering the name for a new profile. Switching profiles is as simple as selecting your preferred profile in the dropdown menu. Users can delete profiles by pressing the x next to a profile name in the dropdown menu. Note that you cannot delete the Default Profile.
