Can you explain why is this happening?

Prettier Version: 1.6.1 / master

Code

Instead of this:

assert.equal(this.$().text().trim(), true);

in VSCode I have this on prettify (LAlt + LShift + F):

assert.equal(
  this.$()
    .text()
    .trim(),
  true
);

Why?

I think single line is better no?

I have all default. Latest versione (stable) of VScode and latest version of Prettier plugin for VScode.

Unfortunately, making a pretty printer that works perfectly in 100% of the cases is not possible in practice, so we have to make tradeoffs. We tried --really hard-- to make it work with line width but issues kept coming in with code that was very hard to understand because of it.

In case of those pieces of code that are very hard to print in a good way, we opted to err on the side of minimizing cases where the output looks terrible and makes the code harder to understand even though there are legit cases (like yours) where the code is going to look not optimal, but isn’t the end of the world.

I’m closing it so quickly because it’s not a new issue that hasn’t had much thoughts put in. I probably spent a month full time trying to make chained method calls work great. We’re unlikely going to be able to solve your use case, I’m afraid.

I think you shouldn’t close the issue anyway. Maybe someone have a clue.
