Update README.md Mention that project has moved into the sdk repository.
This has moved into the Dart SDK repository.
This repository is not kept up-to-date.
Dart Kernel is a small high-level language derived from Dart. It is designed for use as an intermediate format for whole-program analysis and transformations, and as a frontend for codegen and execution backends.
The kernel language has in-memory representations in Dart and C++, and can be serialized as binary or text.
Both the kernel language and its implementations are unstable and are under development.
This package contains the Dart part of the implementation and contains:
Checkout the repository and run pub get:
git clone https://github.com/dart-lang/kernel cd kernel pub get
bin/dartk.dart from the command-line to convert between .dart files and the serialized binary and textual formats.
dartk expects the
.dill extension for files in the binary format. The textual format has no preferred extension right now.
dartk foo.dart # print text IR for foo.dart dartk foo.dart -ofoo.dill # write binary IR for foo.dart to foo.dill dartk foo.dill # print text IR for binary file foo.dill
-l flag to link all transitive dependencies into one file:
dartk myapp.dart -ppackages -l -omyapp.dill # Bundle everything. dartk myapp.dill # Print it back out in a (very, very long) textual format.
If you plan to make changes to kernel, get a checkout of the Dartk SDK and run:
tool/regenerate_dill_files.dart --sdk <path to SDK checkout> pub run test
Linking from binary files is not yet implemented. In order to compile a whole program, currently everything must be compiled from source at once.
