Joseph Frazier 69808cebfb Format JSON literals like object literals (#2181) 
* Format JSON literals like object literals

Following up on commit a42db30 (https://github.com/prettier/prettier/issues/2173),
this change makes it so that literals in JSON files are formatted as
they would be in an object literal. This normalizes trailing zeroes,
exponential notation, unnecessarily escaped characters, etc.

It works by using babylon to parse literals as expressions, and putting
the result in the AST instead of a `json-literal` node. Since JSON
string literals have to be double-quoted, there's a new
`__prettier__isJson` flag on each node, which is used by the printer to
force double-quotes.

* json: Check options.parser when formatting StringLiteral

This is instead of having a custom AST property. See
https://github.com/prettier/prettier/pull/2181#discussion_r122578251

* multiparser: Use babylon.parseExpression

See https://github.com/prettier/prettier/pull/2181#discussion_r122578354

* json: Don't split result AST node into two

See https://github.com/prettier/prettier/pull/2181#discussion_r122578499

* json: Don't use babylon parser to build expression nodes

See https://github.com/prettier/prettier/pull/2181#discussion_r122579052

* Revert "multiparser: Use babylon.parseExpression"

This reverts commit 3d7a4362880d39fac0cea88b5d0186a29538cf6f.

* Remove unused parameter from babylon parser

* json: Remove unused constructorTypes

Joseph Frazier a42db30946 Add JSON support (#2173) 
* Add JSON support

This fixes https://github.com/prettier/prettier/issues/1973 by using
[json-to-ast] to parse JSON, then converting the AST into a
mostly-Babylon AST, so as to piggyback on the existing printer logic.

Identifiers and literals are currently printed verbatim from the input,
but this could be improved upon later (at least for literals, not sure
about identifiers).

[json-to-ast]: https://github.com/vtrushin/json-to-ast

* Rename `json-to-ast` parser to `json`

See https://github.com/prettier/prettier/pull/2173#discussion_r122574644

* json: Use createError to have a pretty error

See https://github.com/prettier/prettier/pull/2173#discussion_r122574748

* json: Transform AST without mutations

Christopher Chedeau 62b9e29af5 Fix comments in non strict mode (#2114) 
It turns out that by returning there, we didn't go through the line `delete ast.tokens` and the comments attachment logic would attach it to a random token. It's great that this fail-safe caught this bug!
