This pull request aims to fix the issue of excessive nesting brought up in the following comment: https://github.com/prettier/prettier/issues/737#issuecomment-392541493
This "fix" is very simple. It adds a new possible way to activate JSX mode for ternary operators. If the first non-conditional parent of the expression is a JSX expression container, then JSX mode gets activated.
This branch also contains a test case for said scenario.
- preserve trailing spaces in html, excluding html comment
- `doc-printer` is now unrelated to `options.parser`
- fix some cases that two trailing spaces are mis-considered as `break`
Fixes#4605
The AST here is actually two `html`s and it did follow the [CommonMark spec](https://spec.commonmark.org/0.28/#html-blocks), so I ended up with respecting the blank line between block `html`s.
* Add various tests for ts type annotated function properties.
* Improve format when passing ts arrow function with return type
* Add test for case from #2581.
* Add a single test suite for blank files in all parsers
The parsers that don’t yet support blank files have been filtered out of the list until they do.
* Don’t directly `require()` Prettier
* Update `require`
* Add missing Babylon parser
* Update snapshots
We landed a change that added a new `InterpreterDirective` AST node type for hashbangs, and no longer add it as a comment/leadingComment.
Ref: https://github.com/babel/babel/pull/7928
I mimicked what we do in `@babel/generator` here, since I found it better than trying to add comments to the ast in `parser-include-shebang.js`). Definitely open to a better/cleaner option though!
Note: I'll follow this up with enabling tests for https://github.com/prettier/prettier/pull/4543 and https://github.com/prettier/prettier/pull/4540 once they land too.

* Don’t break unless `proseWrap` is `always`
* Test `proseWrap: never` on link references
* Added support for the graph ql comment tag
As described in the issue https://github.com/prettier/prettier/issues/4360
Prettier still adds a space inbetween the comment tag and the template literal.
* Added comment explaining the random spaces around GraphQL
* Fixed failing AST_COMPARE tests
* Add tests showing existing behavior of various TS casts.
* Improve formatting of TS casts with generics and unions.
By adding a soft break between the cast and the expression. Also
includes wrapping parentheses for clarity as suggested in #4171.
Avoids changing behavior at all though if casting an array or object
literal because those already have good behavior where the array or
object literal breaks before the cast does so including them would just
result in a pointless extra layer of parentheses that would add no
clarity.
* Update tests in prepation for updating long cast format.
* Update so nested breaks inside type cast are indented.
* Add tests where expression being cast is too long itself.
* Update cast formatting to only sometimes break after cast.
Specifically it will break after the cast if that makes the cast itself
fit on a single line. If the cast itself won't fit on a single line then
the expression being cast will be placed directly after the `>` at the
end of the cast.

* chore(js): improve readablity a little bit
* Upgrade flow to 0.64
This also enables spread operator on jsx on the flow parser:
```js
<div>{...list}</div>
```
I had no idea it was even a thing.
I had to comment out a flow test that no longer parses, but it's no longer in the flow repo and the comment said that it shouldn't be working anyway so I don't think it's going to be a problem.
* Fix build script
* Treat define calls like require
See issue #3829. This commit keeps define calls as a unit when possible,
to prevent an extra indent in the body of an AMD-style define.
Rather than adding the "define" check in the same case as the existing
"require" check, I added a separate condition to explicitly call out the
fact that this checks for both AMD and CommonJS modules.
`yarn test -u` yields no changes, and `yarn lint` passes successfully.
* Added tests for define and require amd formatting
This tests the solution for issue #3829.

* Removed console logs
* Update GraphQL parser
Fixes#3601
This adds support for
- description as strings
- extending all the possible types
- block strings
- allow removing {} if there's no implementation for all graphql types
This is a breaking change but shouldn't be a big issue.
- Empty types are no longer allowed (there's an option to enable it but it hasn't been released yet). The fix is to remove `{}`
Something that hasn't been changed because not released:
- Doesn't support the new `&` separator for implementing multiple interfaces
A bug has been fixed:
- Now properly prints @directives for unions.

* Rebase after plugin change
* Added ignores to code coverage
There's a lot of demand for vue sfc (#2097). This introduces partial support for them: all the html is printed as is, except for the script and style tags which are printed using prettier. I believe that this should cover a lot of the use cases while being simple to support and if we want we can extend to more in the future.
I copy pasted the html parser used by vue (it's just a single 400 lines file) so that we don't run the chancesof conflicts. I'm also very conservative: I only print the style and script at the top level and for the lang attributes we support.
I expect this to be landable as is and provide value, review welcome :)

* Don't lowercase element names and attribute names in selectors
https://www.w3.org/TR/css3-selectors/#casesens
> All Selectors syntax is case-insensitive within the ASCII range (i.e.
> [a-z] and [A-Z] are equivalent), except for parts that are not under the
