TypeScript

Scalable JavaScript development with types, classes and modules.

Install

npm install -g typescript

Usage

tsc hello.ts

Build

1. Install Node if you haven't already (http://nodejs.org/)
2. Install Jake, the tool we use to build our compiler (https://github.com/mde/jake). To do this, run "npm install -g jake".
3. To use jake, run one of the following commands:
   • jake local - This builds the compiler. The output is in built/local in the public directory
   • jake clean - deletes the build compiler
   • jake LKG - This replaces the LKG (last known good) version of the compiler with the built one.
     • This is a bootstrapping step to be executed whenever the built compiler reaches a stable state.
   • jake tests - This builds the test infrastructure, using the built compiler.
   • jake runtests - This runs the tests, using the built compiler and built test infrastructure.
     • You can also override the host or specify a test for this command. Use host=<hostName> or tests=<testPath>.
   • jake baseline-accept - This replaces the baseline test results with the results obtained from jake runtests.
   • jake -T lists the above commands.

To experiment with the --safe mode, see the Makefile in samples/SafeTypeScript, specifically bench safe targets

To bootstrap the compiler in --safe mode

1. make safe Should produce built/local/tsc.safe.js

2. make safe.boot Uses built/local/tsc.safe.js to generate built/local/tsc.boot.safe.js If these two files are identical, you have successfully bootstrapped Safer TypeScript
