PeasyDiff is a replacement for Xfdiff-cut in the Utility menu. It has a simpler drag-and-drop file selection method and fewer distracting graphics. The default display is vertical, or you can select "Side-by-side" and get a two-column display.

PeasyDiff also dumps its output into the file /tmp/PeasyDiff.txt for "off-line" use. Click the View button to open the file in a text editor.

PeasyDiff can compare two individual files or a pair of folders.

The Spacing option includes differences in white space when files are compared. If you turn it off, any differences in spacing are ignored.

----------------------

Version 1.4 introduces a configuration file to hold the PeasyDiff settings. Look for the hidden file /root/.peasydiff.

Code:
export DIMENSIONS="40 120"
export VERTOPTIONS=""
export SBSOPTIONS="-y --suppress-common-lines --width=130"
export FONT="Monospace bold 12"

DIMENSIONS sets the size of the output window.
SBSOPTIONS sets the diff command options for side-by-side output.
FONT sets the display font.

If you accidentally break the file, just delete it and restart PeasyDiff.

Hi rcrsn51.

Thanks for this very useful visualization utility for diff.

Hi rcrsn51
I welcome the addition of another 'diff'. However, the display on my first pair of files was less than stellar.

The line separating the columns got broken and when I dragged the edges of the display to see if I could adjust the output, I found the display would not scale; a large white space was left on rhe right side.

See attached part of the display.

I want this to work.

Thanks for reporting this. PeasyDiff is pretty simple - it just takes the output of the diff command and dumps it into an Xdialog text box. With regular vertical display, this is good enough.

With side-by-side display, there are two problems.

1. The diff command uses tab characters to align the columns. If you run diff in a terminal window this works correctly. But in the Xdialog box, the tabs get messed up.

2. A terminal window uses a fixed-width font for proper alignment. Xdialog claims to have this option, but I can't get it to work.

But there is a partial solution. Get v1.2 above and run side-by-side. The Xdialog display will still be wonky. But the file /tmp/PeasyDiff.txt will now align properly. If you are looking at a complicated comparison, this is probably the best way to do it.

[Edit] To make this easier, I have added a View button that takes you directly to the text file.

If you want to change the comparison method for side-by-side, look at line 10 of /usr/sbin/peasydiff and modify the OPTIONS variable.

Just as you wrote: display still wonky but file /tmp/PeasyDiff.txt and View are OK.
This will do. Thanks.

This will do.

I will also have a fix for the Xdialog display shortly.

What's the constraint that limits the output (both Diff and View) to 64 chars per line?

Run: diff --help

Check out the "--width=NUM" option.

[Edit] In v1.4, you can set this with the configuration file:

Code:
export SBSOPTIONS="-y --suppress-common-lines --width=150"

I tested this. It appears to make the two columns 75 characters wide.
