Gawk stable news: new loadable builtin in CVS

[Aharon Robbins]

I have just added a new example loadable builtin in the gawk stable
CVS repository. It provides the ability to dump an array to a file as
binary data and read it back. This should, in theory, be faster than
dumping / restoring arrays as text.

I have tried to write binary data in network order, with the exception of
the double floating point number. I'm not sure what to do about that yet.

In the meantime, check it out.

Thanks, this looks like an interesting new extension.

One idea is to copy the logic of Sun's xdr_double implementation. I'm
not certain how portable that truly is, but it has definitely worked
for me between sparc, i386, and x86_64 architectures. The code can be
found in glibc in sunrpc/xdr_float.c.

The code to restore the the array from the dump was broken. It's now fixed.

Enjoy.
