PackageCompiler class

Compiles a multi-module ball Program into a full Dart package, producing one .dart file per non-std module.

Output layout

Module names are converted back to file paths using the inverse of PackageEncoder.filePathToModuleName:

Entry module

The module referenced by Program.entryModule is compiled with a main() entry function. All other user-defined modules are compiled without one.

pubspec.yaml and package manifest files

PackageEncoder embeds pubspec.yaml, pubspec.lock, and other root-level config files as assets in the __assets__ module. writeToDirectory extracts them verbatim — no reconstruction needed.

Usage — in memory

final compiler = PackageCompiler(program);
final files = compiler.compileToMap();
// files: { 'lib/src/models.dart': '// Generated ...\nclass User { ... }', ... }

Usage — write to disk

final compiler = PackageCompiler(program);
compiler.writeToDirectory(Directory('/path/to/output'));
