Hi,
I ran into another issue with the potentially inordinately long `portbuildpath`
names, and started thinking of ways to avoid hitting a hard limit on the
argument length list, using a unique shortened version of `portpath`:
1) if the traditional `portbuildpath` already exists, use that
2) otherwise, calculate a unique hash of ${portpath} and use that as the parent
for the `work` directory instead of `subst '/' _ ${portpath}`
I'm not necessarily proposing that as a change in "base", but would like to try
it locally (it sure should beat redefining this information from inside a
Portfile...).
Where would I implement 1) and 2), and what functions does Tcl have to
calculate a useful hash or unique shortened version of a generic string?
There's no `string hash` function as far as I've seen.
Thanks,
R.
