New submission from Michael O'Rourke <mkoro...@adobe.com>:
If you try to difference the attached files with difflib and a html difference
it take 10 minutes or more. In comparison other differencing tools like windiff
and araxis merge will show the diff within a second.
Example code I'm using is:
sourceText = open("source.xml", "rU").readlines()
targetText = open("target.xml", "rU").readlines()
html_diff = difflib.HtmlDiff(tabsize=4)
result = html_diff.make_file(sourceText, targetText, "Source", "Target",
context=True, numlines=10)
f = open('c:/libdiff_html.html', 'w')
f.write(result)
finish()
