.d.ts generator

This is a fork of dts-generator patched to work better with autodts.

Generates a single .d.ts bundle containing external module declarations generated from TypeScript files.

What does this mean?

If you have a project with lots of individual TypeScript files that are designed to be consumed as external modules, the TypeScript compiler doesn’t allow you to actually create a single bundle out of them. This package leverages the TypeScript language services in TypeScript 1.4+ to generate a single .d.ts file containing multiple declare module 'foo' declarations. This allows you to distribute a single .d.ts file along with your compiled JavaScript that users can simply reference from the TypeScript compiler using a /// <reference path /> comment.

.d.ts generator will also correctly merge non-external-module files, and any already-existing .d.ts files.

Usage

1. npm install dts-generator

2. Generate your d.ts bundle:

   Programmatically:

require('dts-generator').generate({ name: 'package-name', baseDir: '/path/to/package-directory', files: [ 'a.ts', 'b.ts', ... ] out: 'package-name.d.ts' });

   Command-line:

   ```bash
dts-generator --name package-name --baseDir /path/to/package-directory --out package-name.d.ts a.ts b.ts ...

Grunt:

module.exports = function (grunt) {
 grunt.loadNpmTasks('dts-generator');
 grunt.initConfig({
 	dtsGenerator: {
 		options: {
 			name: 'package-name',
 			baseDir: '/path/to/package-directory',
 			out: 'package-name.d.ts'
 		},
 		default: {
 			src: [ '/path/to/package-directory/**/*.ts' ]
 		}
 	}
 });
};

3. Reference your generated d.ts bundle from somewhere in your consumer module and import away!:

///

import Foo = require('package-name/Foo');

// ...

## Options

* `baseDir: string`: The base directory for the package being bundled. Any dependencies discovered outside this
  directory will be excluded from the bundle.
* `excludes?: string[]`: A list of files, relative to `baseDir`, that should be excluded from the bundle. Use the
  `--exclude` flag one or more times on the command-line.
* `externs?: string[]`: A list of external module reference paths that should be inserted as reference comments. Use
  the `--extern` flag one or more times on the command-line.
* `files: string[]`: A list of files from the baseDir to bundle.
* `eol?: string`: The end-of-line character that should be used when outputting code. Defaults to `os.EOL`.
* `indent?: string`: The character(s) that should be used to indent the declarations in the output. Defaults to `\t`.
* `main?: string`: The module ID that should be used as the exported value of the package’s “main” module.
* `name: string`: The name of the package. Used to determine the correct exported package name for modules.
* `out: string`: The filename where the generated bundle will be created.
* `target?: ts.ScriptTarget`: The target environment for generated code. Defaults to `ts.ScriptTarget.Latest`.

## Known issues

* Output bundle code formatting is not perfect yet

## Thanks

@fdecampredon for the idea to dump output from the compiler emitter back into the compiler parser instead of trying to
figure out how to influence the code emitter.
