* Add comments showing parser arguments Since this is how they are invoked, the comments make it easier to maintain. * Use babylon.parseExpression for JSON See https://github.com/prettier/prettier/issues/2378#issuecomment-314600778 Note that this doesn't yet print comments: echo '{/*comment*/"K":"V"}' | ./bin/prettier.js --parser json * Remove parser-json.js This reduces duplicate code in the built package. See https://github.com/prettier/prettier/pull/2476#pullrequestreview-50181398 * Add test with block comment in JSON * Fix test with block comment in JSON * Add test with line comment in JSON * Don't build now-redundant parser-json.js
