recommend iojs

[jonathanong]

one thing i'd like to wait for is for nvm/travis to support iojs and start testing on that. i could also push this now

[jonathanong]

shit i forgot the bash command...

[jonathanong]

nvm i don't know what i'm doing haha

After I installed iojs, i got a command iojs. At the same time, it aliased my system node executable to iojs. Essentially, when you run node xx, it called iojs executable.

/usr/local/bin/node -> iojs

Should we stick with node, by default, iojs will be called when user execute the node binary.

Well, I have not tested in nvm cases, that may need to run iojs explicitly.

but the commands don't run with node --harmony-generators if it's iojs. what i thought i was doing was something like alias iojs ?= node --harmony-generators but apparently i forgot how to bash

[mattma]

alias iojs='node --harmony-generators '

 ➜ which iojs
iojs: aliased to node --harmony-generators

 ➜ iojs xxx.js
node: bad option: --harmony-generators

From iojs docs,

The current behaviour of the --harmony flag on io.js is to enable staged features only. After all, it is now a synonym of --es_staging.

I think the correct Bash command should be

# put it in .bashrc, or .zshrc
alias iojs='node --harmony '

Test the command above

 ➜ which iojs
iojs: aliased to node --harmony

 ➜ iojs xxx.js
# run and log stdout...

[jonathanong]

how do you only alias iojs if it doesn't exist yet

[mattma]

After some tests on this matter, I think this could be a solution.

if [ ! -x "$(command -v iojs)" ]
then
  alias iojs='node --harmony '
fi

typically you do NODE ?= node and run make with NODE=iojs set etc

[jonathanong]

i'd like tests to run without iojs users having to do NODE=iojs :D

[tj]

why? there's only a few people that work on the tests, or we can default it to iojs instead

[jonathanong]

yeah we can default to iojs
