annotate trunk/src/main.d @ 309:b4d842b0d2c7
- Added new files Settings.d, config.d and lang_en.d
- Removed redundant break statements from Lexer.d.
- Added function Cast() to SyntaxTree.d.
- Relocated compiler version info to Settings.d.
- Removed messages variable from module Messages. Compiler messages are loaded dynamically now.
- Relocated some functions from module Information to module Messages, and added some format functions to it.
- Message tables are located in their own lang_*.d files.
- Added getString() method to class StringLiteralsExpression.
- Module Settings has a static struct GlobalSettings. It loads global settings from config.d and a language file.
