Move standard --format into a separate module

[mafintosh]

Currently around ~1/3 of the dependencies are there to support standard --format. I propose we move that command to a separate module standard-format since it isn't related to linting and would make standard a lot "lighter" to install.

[bcomnes]

I am okay with this, and maybe revisit adding it back if we can get it down to a much smaller set of deps.

[bcomnes]

We should pull the editor plugin authors into this discussion too

cc @stephenkubovic thoughts?

[yoshuawuyts]

yeah, +1 on not including standard-format by default. Making standard lighter would be a good thing. Perhaps make standard -F run standard-format if it's available? Perhaps that would just be more confusing so I'm not sure.

[stephenkubovic]

+1. This should also avoid formatting issues being opened in the linter.

Here are some real-world measurements with npm3.

With standard-format built-in (two runs):

npm i  25.38s user 5.98s system 62% cpu 49.785 total
npm i  26.71s user 5.58s system 68% cpu 47.242 total

Without standard-format:

npm i  13.11s user 3.05s system 56% cpu 28.585 total
npm i  14.33s user 3.18s system 58% cpu 29.767 total

So it cuts install time in half. And it removes the following dependencies:

I'm okay with removing standard-format. This is a breaking change, so let's batch it with the other breaking changes for v6.0.0. I added a v6 tag for this.

[mafintosh]

\o/

[bcomnes]

Also, standard-format is definitely looking for some help.

There are lots of ES6 issues that probably require modification of upstream deps, and some attention to reducing the number of dependencies that it pulls in would also improve things a lot. It works great for the tried and true ES5 style JS, but you end up having to work around it for ES6 and react stuff.

I'll try to clean up the issues over the next week and document ways people can help out.

[Flet]

👍

I like @yoshuawuyts idea of running standard-format if its available when using -F. especially since its been available for so long.

[jzaefferer]

You can print an error otherwise, something like "standard-format is no longer bundled with standard, you need to install it separately"

[bcomnes]

Never done anything like that before, but I like the idea, with the fallback to a message like @jzaefferer mentioned.

[feross]

Maybe we can do a standard-format hackathon and try to fix most of the open issues. standard-format is a big reason why lots of people like to use standard.

[Flet]

Yes, a hackathon for getting standard-format patched up would be awesome! It may also turn into an esformatter hackathon really... but maybe @millermedeiros would not mind this? :)

[tjmehta]

@feross lmk about a standard-format fixes hackathon. I would love to lend a hand.

[feross]

This is completed now, and in the v6 branch.

[tunnckoCore]

Why not just moved it to devDependencies and save the --format option, i think it would have same effect? I'm just curious, i have both of them installed globally either way.

[watson]

@tunnckoCore devDependencies are not installed when installing a module using npm install <module> - neither globally or locally. They are only installed when running npm link or npm install from the root of the module having the devDependencies.

[tunnckoCore]

@watson I know that. And exactly because of that, this will throw to the users and they will install it if they want/use formating.
I like to use this technic for optional things. For example in request-all package and delegate-properties.
I think that's the better way instead of dropping support at all, worth nothing and saves functionality.

[junosuarez]

My CI builds thank you 🙌

[feross]

[dcousens]

I think keeping standard --format with an error saying "install X package" is a sane deprecating option, and even long term.

SGTM.

[feross]

@dcousens @bcomnes @tunnckoCore This change is already shipped in standard v6.
