Browserlist support

[leimonio]

This is more a kind of question:

• Would it make sense if postcss-calc transformations were based on the browsers support configured through browserlist?
• How would this affect postcss-calc?
• If postcss-calc is not the correct repository to implement such logic, which one would be? Would it be cssnano-preset-default or a different one?

For example by using cssnano-preset-default we can define this configuration in postcss.config.js:

module.exports = {
   plugins: [
       require('cssnano')({
         preset: ['default', {
             calc: false,
         }]
       }),
   ],
};

@leimonio what transformation of calc doesn't work in some browsers, but works in other?

[leimonio]

I mean mostly based on browser support. e.g. there are browsers supporting inner calc whereas others not, right? Or otherwise, based on full/partial/not all support enable different strategies of transformations or totally disable them. I'm not sure if this makes sense.

Yep you are right https://caniuse.com/#search=calc (Known issues), feel free to send a PR

It should be easy and you can see how we do this in cssnano

[leimonio]

Sounds good, I'll a look at the repo. Is there something you'd like to share as guidance? Closing this issue, since it's irrelevant to the scope of this repo.

[alexander-akait]

@leimonio don't this it is out of scope, because i can't disable some changes in calc optimization in cssnano, let's open this

[leimonio]

Accidentally closed it twice. I’d like to contribute on that.
