# CompareFiles -
|
|
# Compare two source files and show the differences
|
|
#
|
|
# Usage:
|
|
# CompareFiles [-9 | -13 | -b x y | -Portrait | -TwoPage] oldFile newFile - open up the files and add menu
|
|
# -9 use 9 inch screen (512 x 342)
|
|
# -13 use 13 inch screen (640 x 480)
|
|
# -Portrait use 15 inch screen (640 x 870)
|
|
# -TwoPage use 21 inch screen (1152 x 870)
|
|
# -b x y use screen dimensions given in x y
|
|
# default is -13
|
|
# NOTE:
|
|
# Order of parameters is important
|
|
# No error checking is done on x y coordinates
|
|
#
|
|
# Returns:
|
|
# Status = 0 - files match
|
|
# Status = 1 - syntax error
|
|
# Status = 2 - files differ (this is the same status as the Compare tool)
|
|
#
|
|
# CompareFiles will compare two files, and if they don't match it will
|
|
# bring them both up on the screen and put them side by side. A menu will be
|
|
# appended to the menu bar to go through the changes. When all the changes
|
|
# have been shown, the file windows will be restored and closed.
|
|
#
|
|
# The differences are shown from bottom to top so that if any changes are made
|
|
# in the files, the line offsets are not messed up.
|
|
#
|
|
# This creates two temporary files {ShellDirectory}Compare_File and
|
|
# {ShellDirectory}Compare_State.
|
|
# These are deleted on exit.

# Understanding the code…
|
|
#
|
|
# CompareFiles is actually a few scripts rolled into one. The action
|
|
# depends on the parameters. Here is what happens:
|
|
#
|
|
# CompareFiles oldFile newFile
|
|
# Do the actual compare
|
|
# If there are differences, it will
|
|
# Create a script to execute on quit
|
|
# Move the windows around next to each other
|
|
# Create the Compare Menu
|
|
# Call itself with -n
|
|
# CompareFiles -n - show next change
|
|
# CompareFiles -old - Paste change from old into new
|
|
# CompareFiles -new - Paste change from new into old
|
|
# CompareFiles -q - execute quit script
|
|
#
|
|
|
|
