I am trying to add a plugin to the TypeScript compiler and so I added my code and I compiled tsc.ts. It compiles correctly, but when I run, it's missing some variables that are declared in io.ts. I removed my changes, and it still doesn't work. So I tried this:
file: a.ts
var a : number = 5;
file: b.ts
///<reference path='a.ts' />
console.log(a);
and then compile: tsc b.ts which gives me a.js and b.js.
When I try to run b.js (I do node b.js), the variable a is undefined.
This is what the content of b.js:
///<reference path='a.ts' />
console.log(a);
and so it makes sense that a is undefined, since a is nowhere in this file and so is a.ts.
Am I compiling it wrong, or executing it wrong.. or what?
If you're running under node, you should use export and import to manage cross-file dependencies.
a.ts
export var x = 5;
b.ts
import a = require('./a');
console.log(a.x);
Compile with --module commonjs
If you were running on the web you could use --outFile to concatenate into a single file, but that's usually not a good option under node.
