Fmt is the raw formatter used by Printf etc. Not meant for normal use.

See print.go for a more palatable interface.

The model is to accumulate operands into an internal buffer and then
|
2009-03-06 04:35:38 -07:00
|
|
|
retrieve the buffer in one hit using Str(), Putnl(), etc. The formatting
|
|
|
|
methods return ``self'' so the operations can be chained.
