1.4 Release

[vjeux]

Starting this issue to track what needs to be done for the 1.4 release:

TypeScript support:

• Add TypeScript to the help
• Bundle the dependencies Split bundle before shipping to npm #1640

TypeScript formatting blockers:

• Comments inside decorator arguments are moved to the wrong line #1460 Comments inside of decoratos
• Missing AST Type #1694 Comments inside of function types
• Unstable yield re-print with TypeScript parser #1769 generator functions
• Missing default modifier for TSNamespaceExportDeclaration eslint/typescript-eslint-parser#288
• Incorrect optional flag on Identifier eslint/typescript-eslint-parser#289
• Missing computed flag on TSMethodSignature eslint/typescript-eslint-parser#290
• Async generator method is not flagged as a generator eslint/typescript-eslint-parser#297

Facebook blockers:

• Do not break on extends #1520 Do not break on extend
• !() indentation #774 !() indentation
• Inline import from for a single one like we do for require
• Update to flow 0.47.0
• Extra space in flow type #1724 Extra space in flow type

Things that are easy we should knock down:

• Forces variable declarations onto single line #1607 Make multiple variable declarations on their own line

It's going to be pretty awesome :)

@vjeux Should we mention in the Readme/release that TypeScript 2.3 is required? (this is a requirement of typescript-eslint-parser)

[vjeux]

I'm now bundling everything so prettier is now dependency-free. https://unpkg.com/prettier@1.4.0/src/

[JamesHenry]

TypeScript is a peerDependency of the parser, so I think @azz's point still stands, @vjeux. The first step in the process is that the code is parsed using the TypeScript compiler, so it does have to be there and the version is important in various cases.

TypeScript 2.3 is the supported "major" version (based on how TS handles version numbers), typescript-eslint-parser will log a warning to the console if another version is being used.

I think the simplest thing would be to link to this: https://github.com/eslint/typescript-eslint-parser#supported-typescript-version

[vjeux]

@JamesHenry The npm version of prettier has 0 dependencies. I'm bundling all the dependencies in a single parser-typescript.js file that includes typescript 2.3, typescript-eslint-parser, all their dependencies... This way, you can just drop in prettier and "it just works".

[JamesHenry]

Ah, I see, TypeScript is also included in that - that's awesome 😄

Is the TS version that's bundled dictated by the devDependency of this project?

[vjeux]

Yes, https://github.com/prettier/prettier/blob/master/package.json#L44

[JamesHenry]

Great 👍 I'll make sure that gets updated as and when the stable version of TypeScript changes
