When sourcing a script without parameters in zsh the sourced scripts
gets the same parameters as the sourcing file and is able to modify
these parameters. Prevent nvm from removing all parameters of sourcing
script by processing a copy of the parameters in a function.
This commit adds (optional) support for additional sha256 checksum utilities
for newer versions of node.js and io.js that use sha256 checksums rather than
sha1.
If nothing is found to do a sha256 checksum on the client machine, a warning is
printed and things continue on as normal.
Following comments from @ljharb on incorporating some of @DomT4's PR
creationix/nvm#664, and making this checksum optional. If I could I would
gladly include this as an addon to the now closed PR creationix/nvm#664. I am
choosing not to file it onto that PR because it's closed and (currently)
significantly behind the master branch.
@DomT4 did the hard work of actually finding all the different ways in which
one could verify a sha256 checksum, I've just included those here in an effort
to move forward with sha256 checksum support.
Add prompt when there is no binary for node version greater than v1.0.0
Currently, on FreeBSD, if we try `nvm install 4.2`, we will only get:
> Installing node v1.0 and greater from source is not currently supported
In fact I had no idea what's wrong because I didn't use `-s` parameter for it,
and then I found that there are two reasons:
1. There was no pre-built nodejs binary from official for FreeBSD, which means we need to build from source.
2. nvm doesn't support build for v1.0 and greater version from source yet.
So I think there should be a prompt message to tell the user about the reason why nvm will go to build from source,
no matter it will succeed or fail.
