Accept input from stdin

[Walnuts]

I would like to be able to accept input from stdin so that html can be piped to it. For example, to convert from markdown to pdf, you could:

$ Markdown.pl test.md | wkpdf --output test.pdf

I had planned to add this feature for a long time since it is good Unix tool practice to read from stdin. However, due to a bug in a the NSUrlConnection class, supporting reading from stdin in a natural way was not possible.

The good news is, that I have tried, whether this bug in NSUrlConnection still exists and a quick test revealed that the problem has probably been fixed in a recent OS X upgrade.

Could you please check, whether the following command works? If so, I will revise the command line interface to read from stdin if no --input argument is specified.

$ Markdown.pl test.md | wkpdf --input file:///dev/stdin --output test.pdf

it works using --source instead of --input. In a similar vein, I think it would be nice to be able to easily direct output to stdout, maybe like wget does? In other words, maybe alias --output with -O, and make -O- or maybe -O -- redirect to stdout?

I have just released an update to wkpdf which reads from stdin if no --source argument is specified.

Unfortunately, it seems that the Cocoa printing libraries do not like printing to stdout. Hence, if wkpdf should support saving to stdout, a workaround needs to be implemented. Basically its no big deal, I just need to find some time to do this. Hence for the moment I will add this to the issue tracker as feature request.

If this feature is important/urgent for you, contributions are welcome.

Printing to stdout is not urgent, just wanted to suggest it. Thanks for the help with stdin!
