Hi all
The current way to do this is:
char foo[]="blah blah blah";
KBuf bar;
bar.assign(foo);
Is this inconvenient enough?
The previous
KBuf foo="blah" syntax worked via the KBuf(const char *) constructor
which I've currently commented out.
I have posted a doxygen-generated interface specification at
http://www.kinkie.it/pub/dox/, which I'd invite you all to check out.
There's a quite important aspect I'd like to clear: currently most
manipulation functions modify the KBuf itself, i.e.
KBuf foo.assing("foo");
foo.append(" bar");
// foo now contains "foo bar".
An alternative would be to always return fresh KBuf, or in other words:
KBuf foo.assing("foo");
foo=foo.append(" bar");
The choice was made because it's more efficient, but it may be counterintuitive.
There's a third option, which is to have two operators for most
functions, like i've done with the slice()/sliceCopy() operators. The
downside would be to double the interface size..
Thoughts?
