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		2017-06-17 20:49:22 -04:00
