* Print directive literals verbatim
This addresses https://github.com/prettier/prettier/issues/1555,
but doesn't seem to pass the AST_COMPARE=1 tests:
AST_COMPARE=1 npm test -- tests/quotes -t strings
However, running `prettier --debug-check` on the relevant file *does*
work:
prettier tests/quotes/strings.js --debug-check
* Change directive literal quotes if it doesn't contain quotes
This addresses https://github.com/prettier/prettier/pull/1560#discussion_r115396257
From https://github.com/prettier/prettier/issues/1555#issue-227206837:
> It's okay to change the type of quotation marks used, but only if
doing so does not require changing any characters within the directive.
* Don't change directive literal quotes if it contains a backslash
This passes the `--debug-check` tests again:
prettier tests/quotes/strings.js --debug-check
* Try to add regression test for escaped directive literals
This seems not to work, despite the following command having the correct
output:
echo "'\''" | prettier
You can use the following to get an idea of how flow/typescript parse
this:
node -p "JSON.stringify(require('./src/parser').parse('\\'\\\\\'\\'', {parser: 'flow'}), null, 2)"
node -p "JSON.stringify(require('./src/parser').parse('\\'\\\\\'\\'', {parser: 'typescript'}), null, 2)"
* WIP Disable Flow/Typescript for ./tests/directives
We don't yet handle escaped directives for them, but Babylon works.

This reverts commit 2aba6231271f6985a395c31e3df9323e8f3da115.
* Prevent test strings from being parsed as directives
See https://github.com/prettier/prettier/pull/1560#issue-227225960

* Infer DirectiveLiterals from Flow parser

See https://github.com/prettier/prettier/pull/1560#issuecomment-300296221
* fixup! Infer DirectiveLiterals from Flow parser
* Don't fake objects that look like a DirectiveLiteral
Instead, add a flag to nodeStr() that deals with the Flow node
accordingly. See https://github.com/prettier/prettier/pull/1560#discussion_r115605758
* Print preferred quotes around escaped DirectiveLiteral when it doesn't contain quotes
See https://github.com/prettier/prettier/pull/1560#discussion_r115606122
* Simplify `canChangeDirectiveQuotes` logic
* Add directive test with unnecessarily escaped non-quote character
* Fix boolean logic error
I thought that this would result in the following if-block executing, as
needed to pass the test case in the previous commit. However, it appears
that it's not actually needed to pass the test case, since `makeString`
doesn't unescape unnecessarily escaped non-quote characters.
Nevertheless, I think we should leave that if-block (`if (canChangeDirectiveQuotes)`)
there, in case `makeString` is updated.
See https://github.com/prettier/prettier/pull/1571#discussion_r115658398
* Make isFlowDirectiveLiteral a separate argument to nodeStr()
See https://github.com/prettier/prettier/pull/1571#discussion_r115810988
* Simplify isFlowDirectiveLiteral logic by passing n.expression to nodeStr()
See https://github.com/prettier/prettier/pull/1571#discussion_r115811216
As discussed on #1564, improve the clarity of the descriptions for the bracketSpacing and semicolons options by describing what the options do rather than what their CLI overrides do; These were confusing as written because these options default to true, and their CLI overrides trigger the opposite behavior.

* fixup! Infer DirectiveLiterals from Flow parser
* Fix incorrect options documentation in README
The options section in the README (which appears to be the primary source of truth for documentation) had incorrectly conflated the bracketSpacing and jsxBracketSameLine options into a single table row (using the human readable name for one, the machine readable names for another, and combined descriptions of both). This patch splits the row into two accurate ones.
* Revise previous correction to options documention in README
Incorporating feedback in #1564
* Run AST comparison tests on Travis
It looks like some of these currently fail, so we should probably also
sort that out.
Inspired by https://github.com/prettier/prettier/issues/1552
* tests: Use specified parser when AST_COMPARE=1
This fixes some of the tests with AST_COMPARE=1
* Move cleanAST() into prettier.__debug
This makes it available for tests to use.
* AST_COMPARE=1 uses cleanAst() instead of removeEmptyStatements()
Ths fixes some of the tests with AST_COMPARE=1
* Export parse() from src/parser.js
This makes it available for tests to use.
* tests: Use specified parser more when AST_COMPARE=1
This is a continuation of commit 86437a66d326919897fe89891a25824870f5bb79
This fixes some of the tests with AST_COMPARE=1
* massageAST: remove leadingComments/trailingComments
This fixes some of the tests with AST_COMPARE=1
* massageAST: remove `extra`
This fixes some of the tests with AST_COMPARE=1
* tests_config/run_spec.js: Rename variables for clarity
* AST_COMPARE=1 tests compare unstringified objects
This makes the test error output shorter.
* fixup! Export parse() from src/parser.js
* Revert "Run AST comparison tests on Travis"

* Fix copy/paste error
* fix(typescript): improve handling of computed properties
* test(typescript): add Symbol computed property test
* fix(typescript): do not print brackets for literals
* fix(typescript): fix module block, add enum initializers and fix type parameters
* fix(typescript): use printStatementSequence for TSModuleBlock
* fix(type-params): move typeParameters out of printFunctionParams
* refactor(type-params): move typeParameters out of printArgumentList
I have no idea if it's even valid but it threw on 8 typescript tests, now it doesn't.
