Yes, about time to improve string.format. Do you have any priorities?

[maxlapshin]

No, I don't have any priorities.

I just tried to implement a small part, required for me.

Robert, I really think that some unit tests are required. Unit or common test, what do you like more.

[rvirding]

OK, I will work on it.

Yes, we definitely need tests. I prefer common test, but if you want to use eunit it doesn't bother me. They can always be run from common test. :-)

I also like common test, it is easier to write and has cool html output.

If you will bootstrap some ct environment in develop branch, I'll try to make some pull requests for it.

I have improved formatting in string.format. It is in the develop branch.

It can now handle the conversion specifiers q, s, c, i, d, o, x, e, f, g, %, the field width and precision and the flags 0, -, , +. It cannot yet handle multiple flags and does a poor job with the 0 flag and negative numbers.

I have now fixed formatting in string.format so that it behaves properly. I will add documentation real soon now. It is in the develop branch.
