Colordiff

Text differencing of two PDF files in the terminal using:

• dwdiff

• GNU wdiff

• pdftotext

• colordiff

• GNU Grep

Red text is from the old PDF and green text is from the new PDF. Currently dwdiff provides a slightly better output than wdiff.

Commands used to create the colordiff:

cd test_files\pdf
dwdiff <(pdftotext old/filename.pdf -) <(pdftotext new/filename.pdf -) | colordiff | grep -C 3 '\[-' > dwdiff-colordiff-output.txt

cd test_files\pdf
wdiff <(pdftotext old/filename.pdf -) <(pdftotext new/filename.pdf -) | colordiff | grep -C 3 '\[-' > colordiff-output.txt
