QLColorCode

Original project: http://code.google.com/p/qlcolorcode/

Warning: since Mac OS X 10.10, the plugin should be installed in /Library/QuickLook to work correctly. Problem under investigation.

This is a Quick Look plugin that renders source code with syntax highlighting, using the Highlight library.

To install the plugin, just drag it to /Library/QuickLook or ~/Library/QuickLook. You may need to create that folder if it doesn't already exist.

If you want to configure QLColorCode, there are several defaults commands that could be useful:

Setting the text encoding (default is UTF-8). Two settings are required. The first sets Highlight's encoding, the second sets Webkit's:

defaults write org.n8gray.QLColorCode textEncoding UTF-16
defaults write org.n8gray.QLColorCode webkitTextEncoding UTF-16

Setting the font (default is Menlo):

defaults write org.n8gray.QLColorCode font Monaco

the font size (default is 10):

defaults write org.n8gray.QLColorCode fontSizePoints 9

the color style (default is edit-xcode, see all available themes):

defaults write org.n8gray.QLColorCode hlTheme ide-xcode

any extra command-line flags for Highlight (see below):

defaults write org.n8gray.QLColorCode extraHLFlags '-l -W'

the maximum size (in bytes, deactivated by default) for previewed files:

defaults write org.n8gray.QLColorCode maxFileSize 1000000

Here are some useful 'highlight' command-line flags (from the man page):

   -F, --reformat=<style>
          reformat output in given style.   <style>=[ansi,  gnu,  kr,
          java, linux]

   -J, --line-length=<num>
          line length before wrapping (see -W, -V)

   -j, --line-number-length=<num>
          line number length incl. left padding

   -l, --linenumbers
          print line numbers in output file

   -t  --replace-tabs=<num>
          replace tabs by num spaces

   -V, --wrap-simple
          wrap long lines without indenting function  parameters  and
          statements

   -W, --wrap
          wrap long lines

   -z, --zeroes
          fill leading space of line numbers with zeroes

   --kw-case=<upper|lower|capitalize>
          control case of case insensitive keywords

This version of the plugin use an external Highlight. By default, it uses /opt/local/bin/highlight but it can be changed:

defaults write org.n8gray.QLColorCode pathHL /usr/local/bin/highlight

Highlight can handle lots and lots of languages, but this plugin will only be invoked for file types that the OS knows are type "source-code". Since the OS only knows about a limited number of languages, I've added Universal Type Identifier (UTI) declarations for several "interesting" languages. If I've missed your favorite language, take a look at the Info.plist file inside the plugin bundle and look for the UTImportedTypeDeclarations section. I haven't added all the languages that Highlight can handle because it's rumored that having two conflicting UTI declarations for the same file extension can cause problems. Note that if you do edit the Info.plist file you need to nudge the system to tell it something has changed. Moving the plugin to the desktop then back to its installed location should do the trick.

As an aside, by changing colorize.sh you can use this plugin to render any file type that you can convert to HTML. Have fun, and let me know if you do anything cool!
