pretty printing perl with enscript

I've been using enscript for years to format source code for printing. In particular the -2Gr flags for two-up, landscape prints with "Fancy header".

I recently found there are some colorization flags, -E for syntax highlighting and --color for colored syntax highlighting. -E can take an optional lang flag, perl in our case.

So now my pretty printer uses 'enscript -2Gr --color -Eperl' to create the postscript file and then ps2pdf to dump to pdf.

My perl wrapper and self-referential pdf output. Script requires enscript to be installed.

This is the shell code that the wrapper ends up evaluating:

enscript -MLetter -Gr2 --color -Eperl 'code_to_pdf.pl' -p - | ps2pdf - "$HOME/public_html/pdf/code_to_pdf.pdf"

% enscript --help-highlight |egrep '^Hi|^Name|^Desc|^$'
