The intention is to create a less verbose output. Seems reasonable.
I would suggest to not add a new CLI argument for this, but to combine this idea with the already given verbosity levels (v|vv|vvv). This might be implemented via a verbosity level check, around the output of the suggestions.

@jakoch this would mean the default would have to be changed, as it isnt possible to define a verbosity level lower than the current one.

We might hide the suggestions by default and show them with "-v".

but then some stuff should be moved to a higher verbosity. -v is already outputting lots of stuff

The question really is whether this suggest outputs makes any sense at all? I can't remember ever looking at it.

I think moving it to -v might be better, because I suspect most people don't care about it. I'll ask for feedback.

The feature makes sense in development, I'd like to keep it as is.

I don't often browse Packagist, so reading suggested packages in the terminal is quite useful. Is outputting a few lines at the end really a big deal? oO

I am using suggest i.e. here.
The question is, how important is the information you'll find in suggest?
And how can you access it, when you haven't seen it on installation, like composer.phar suggest?

In case you haven't seen it or missed it on installation: composer --dry-run
With suggestions moved to -v composer --dry-run -v. This makes sense - for me, at least.
So the developer is able to loop up the suggestions, before setting them up and installing them.
He still has to take action; which leads to another (off-topic) idea: composer --install --install-suggests.

@willdurand for one of our projects at work it is well over 20 lines.

I don't think it's a big deal. It probably outputs more stuff before anyway.

@jakoch --install-suggests cannot be done: suggestions are not constraint ranges.

and the initial implementation of suggestions was allowing to install them, but it was just a broken stuff (you may want to install only some of the suggestions, and some suggestions might be incompatible together, making the resolution fail, etc...)

@stof Totally right! I think --install-suggests could be dopped.
E.g. you could also suggest to install nodejs, which is a system package and not really available through composer.

I vote for a) I love this stuff, keep it as it is.

bump? @Seldaek

Generating optimized autoload files

Much cleaner as PR suggests:

composer install --prefer-dist --optimize-autoloader --no-suggest

@Seldaek any update on this?

Closing this one as composer only shows suggested packages if we are --dev.
