I have the iPad 3 and purchased Igowin HD. I love that this allows me to play games at any point during review. But I'm baffled why they allow emailing games out of Igowin but can't import SGF files. Is this an oversight or a deliberate omission?

Might be neither (just not budgeted* to do the work).

There is a big difference between a program doing something (in this case putting into an email) data that it can assume is valid. Quite another to accept and then do something with data which could be garbage. As a rule of thumb, 80% of the code of a process will be handling every conceivable error condition.

For one of these programs to imput SGF files it must be able to detect every (and have handling for) every possible way something could resemble the SGF reprentation of a go game but not be.


* You might consider that a "deliberate omission" but perhaps Fotland was choosing between getting the app out there or delaying till "import" was ready. You could email him to ask if he's planning to add that.
