as follows. If TSS_LOG is not set, no logging will occur. If TSS_LOG is set to any value, logging will occur as before this change (log file will be in directory of tsserver.js with name .logPID where PID is the process id of the server process; log will contain the pre-change messages). If TSS_LOG is set to a string that has the form "-file fileName", the log file will be in the tsserver.js directory with name 'fileName'. If TSS_LOG is set to a string that has the form "-level levelName", then the level of logging will be set to 'levelName'. Currently the two levels are 'normal' and 'verbose'. The TSS_LOG string can contain zero, one or both of its options as in "-file LOG -level verbose". At the verbose level, the server will log every request, response and event, and will also give elapsed time for message processing. |

TypeScript
TypeScript is a language for application-scale JavaScript. TypeScript adds optional types, classes, and modules to JavaScript. TypeScript supports tools for large-scale JavaScript applications for any browser, for any host, on any OS. TypeScript compiles to readable, standards-based JavaScript. Try it out at the playground, and stay up to date via our blog and twitter account.

Documentation
Building
In order to build the TypeScript compiler, ensure that you have Git and Node.js installed.
Clone a copy of the repo:
git clone https://github.com/Microsoft/TypeScript.git
Change to the TypeScript directory:
cd TypeScript
Install Jake tools and dev dependencies:
npm install -g jake
npm install
Use one of the following to build and test:
jake local # Build the compiler into built/local
jake clean # Delete the built compiler
jake LKG # Replace the last known good with the built one.
# Bootstrapping step to be executed when the built compiler reaches a stable state.
jake tests # Build the test infrastructure using the built compiler.
jake runtests # Run tests using the built compiler and test infrastructure.
# You can override the host or specify a test for this command.
# Use host=<hostName> or tests=<testPath>.
jake runtests-browser # Runs the tests using the built run.js file. Syntax is jake runtests. Optional
parameters 'host=', 'tests=[regex], reporter=[list|spec|json|<more>]'.
jake baseline-accept # This replaces the baseline test results with the results obtained from jake runtests.
jake -T # List the above commands.
Usage
node built/local/tsc.js hello.ts
