[Feature Request]: is there an option can be used to exclude iojs?

[zhaojjiang]

In my environment, nvm ls-remote and nvm install sometimes takes long time to connect. I am not sure why this happen (may be network).
I changed NVM_NODEJS_ORG_MIRROR with https://npmmirror.com/mirrors/node/ and it works fine with --lts option (I am not sure if this option applied to filter node?).

The confused thing is that I cannot found an available iojs mirror to speed up NVM_IOJS_ORG_MIRROR.
Is there is an option to exclude iojs? If not, will this be added?

This is a bit of a duplicate of #1080.

tldr, no, there isn't currently an option for that. however, it's very reasonable to allow it to be set to an empty string, and thus bypass the check.

it meens empty string is not allowed for now, right? i tried empty string, it seems like empty string not work

[ljharb]

Correct, it's not allowed for now. I'll add it soon tho.

@ljharb Looking forward to this.

I tried nvm install --lts 18 and it can speed up, but I don't know why, I don't know what is the difference between mirrors handler with option --lts or not, so I can't apply this option to our deploy script, I only use it manually.

Additionally, a valid mirror hub with invalid NVM_IOJS_ORG_MIRROR can get empty iojs versions, which can also be used to exclude iojs.

If you set the iojs mirror env var to an empty string, it should skip that lookup.

I fetched tag v0.40.0, and tried NVM_IOJS_ORG_MIRROR with empty string, it not work, nvm ls-remote still include iojs

[ljharb]

ah, you're right, that commit isn't merged yet - i still have tests to write.
