Practicalities

Once you're done Building the Fletch binaries, you can run your Fletch code in two ways: (1) from source and (2) from snapshot. In the following examples, we assume that you are running on a 32-bit Linux system. You'll have to adjust the path to the fletch_driver and fletch binaries on other platforms.

Running from source

This is the easiest way of running Dart code on top of Fletch. You simply pass the .dart file to run to the fletch_driver binary that matches your platform:

$ out/ReleaseIA32Clang/fletch_driver hello.dart
Hello, World!

Running from snapshot

Running from a snapshot is also simple. You just instruct fletch_driver to output a snapshot and then you run it separately with the raw fletch binary:

$ out/ReleaseIA32Clang/fletch_driver hello.dart --out hello.snapshot
$ out/ReleaseIA32Clang/fletch hello.snapshot
Hello, World!
