What's the best way to print out code (e.g. for a code review)? Eclipse's print option only does portrait (afaict), wich is unreadable for longer lines of code. Opening and printing all files in an editor like gedit is a pain.
Is there some batch code print program available? Or is there some magic command line chain that does it for me?
Of course, I need both line numbers and syntax highlighting.
Printing out source code on paper is a colossal waste of trees. What other solutions have you considered?
I might suggest a product such as Crucible that lets you do code review collaboratively, online in a web browser.
You may have a tonne of code and may need to have it all available for your review. Printing the code is not a scalable solution unless it is probably just a few pages.
I would suggest:
I've found that gvim gives you syntax coloring, line numbers and the ability to print in landscape mode.
We set up the default print options, associate the files (*.c, *.h, etc) with gvim, then just select all the files and right-click, print.
This is for Windows, I'm not sure how you'd do the same thing for non-Windows platform but you didn't specify which you wanted.
a2ps will format code in portrait or landscape mode, with or without line numbers, and has a multitude of other options. It does syntax highlighting for a good number of languages.
I used to use a2ps which resulted in a pretty printed postscript from most languages.
I'm fairly sure you can just tell it to print to a printer.
UPDATE
Here is a link to a page that describes pretty printing using a2ps
I rarely print code, but when I do, I just use my usual editor, SciTE. It offers a decent control over printing.
It also accepts a command line option to print and exit.
I use Highlight (German on the top half of the page, English at the bottom half). I can get code and generate HTML, PDF, whatever and give it a color scheme (there are a number of color schemes available, and I think you can make your own, but I never saw the need for that).
As a printer-interface for any of the above solutions for indentation and syntax highlighting, I've found printFile indispensable and unequaled for general-purpose multi-column printing for years. It has just the right set of switches for wrapping, column-width, font-size, orientation, etc.; and trivial overhead. And it has postscript support.
