Classes
- CharacterLocation
- The location of a character represented as a line and column pair.
- CompilerConfig
- ErrorConfig
- Error processor configuration derived from analysis (or embedder) options.
- ErrorHandlerConfig
- ErrorProcessor
- Process errors by filtering or changing associated ErrorSeverity.
- ErrorSeverity
- The severity of an message.
- ErrorType
- The type of an HTError.
- FutureExecution
- A wrapper class for the bytecode interpreter to run a certain task in a future.
- Hetu
- A wrapper class for sourceContext, lexicon, parser, bundler, analyzer, compiler and interpreter to make them work together.
- HetuConfig
- HTBundler
- Handle import statement in sources and bundle all related sources into a single compilation
- HTCompiler
- Compiles source code into bytecode.
- HTContext
- The exucution context of the bytecode interpreter.
- HTDefaultLexicon
- Default lexicon implementation used by Hetu.
- HTDefaultParser
- Default parser implementation used by Hetu.
- HTEntity
- A interface for store and access symbols from a collection.
- HTError
- HTErrorHandler
- Abstract error handler class
- HTErrorHandlerImpl
- Default error handler implementation
- HTFilterConfig
- HTInterpreter
- A bytecode implementation of Hetu Script interpreter
- HTIntrinsicType
- HTLexer
- HTLexicon
- Lexicon used by Hetu,
- HTLocale
- HTLocaleEnglish
- HTLocaleSimplifiedChinese
- HTOverlayContext
- HTOverlayContext are a virtual set of files that not neccessarily exists as physical files.
- HTOverlayContextManager
- HTParser
- A general parser, with abstract method to parse a token list or string content.
- HTRegIdx
- HTResource
-
HTResourceContext<
T> - HTResourceContext are a set of resources, each has a unique path. It could be a physical folder, a virtual collection in memory, an URL, or a remote database... any thing that provide create, read, update, delete services could be a resource context.
- HTSource
- A piece of code, with extra informations like: fullName, type, lineInfo, etc.
-
HTSourceManager<
RT, CT extends HTResourceContext< RT> > - Manage a set of resources. A resource could be hetu source, yaml, json... etc. Extends this class and provide an implementation of createContext to manage a certain kind of HTResourceContext
- HTType
- Type is basically a set of things. It is used to check errors in code.
- HTTypeAny
-
A type is both
top
andbottom
, only used on declaration for analysis. - HTTypeFunction
- HTTypeNamespace
- HTTypeNever
-
A
bottom
type. A function whose return type is never cannot return. For example by throwing an error or looping forever. - HTTypeNull
-
A
zero
type. It's the type of runtime null value. You cannot get this type via expression or declaration. - HTTypeUnknown
-
A
top
type, basically a type-safe version of the type any. - HTTypeVoid
-
A
empty
type. A function whose return type is empty. It may contain return statement, but cannot return any value. And you cannot use the function call result in any operation. - HTValueSource
- A value, however it can be imported like a source. Typically a json file, which is a HTStruct value in Hetu Script.
- InternalIdentifier
- InterpreterConfig
- Collection of config of bytecode interpreter.
- LineInfo
- Information about line and column information within a source file.
- ParserConfig
- Semantic
- SourceRange
- A source range defines a range of characters within source code.
Enums
- ErrorCode
- FunctionCategory
- Function types
- HTResourceType
- ParseStyle
- Determines how to parse a piece of code
- StackFrameStrategy
- Determines how the interepreter deal with stack frame information when context are changed.
Mixins
- InterpreterRef
- Mixin for classes that want to hold a ref of a bytecode interpreter
Constants
- kStackTraceDisplayCountLimit → const int
-
severityMap
→ const Map<
String, ErrorSeverity> - String identifiers mapped to associated severities.
