Types

type Compiler

type Compiler struct {
	// contains filtered or unexported fields
}

Compiler performs the assembling.

func NewCompiler

func NewCompiler(fsys fs.FS) *Compiler

NewCompiler creates a compiler. The passed file system is used to resolve import file names.

func (*Compiler) CompileFile

func (c *Compiler) CompileFile(filename string) []byte

CompileString compiles the given program text and returns the corresponding bytecode. If compilation fails, the returned slice is nil. Use the Errors method to get parsing/compilation errors.

func (*Compiler) CompileString

func (c *Compiler) CompileString(input string) []byte

CompileString compiles the given program text and returns the corresponding bytecode. If compilation fails, the returned slice is nil. Use the Errors method to get parsing/compilation errors.

func (*Compiler) Errors

func (c *Compiler) Errors() []error

Errors returns errors that have accumulated during compilation.

func (*Compiler) SetDebugLexer

func (c *Compiler) SetDebugLexer(on bool)

SetDebugLexer enables/disables printing of the token stream to stdout.

func (*Compiler) SetIncludeDepthLimit

func (c *Compiler) SetIncludeDepthLimit(limit int)

SetDebugLexer enables/disables printing of the token stream to stdout.

func (*Compiler) SetMaxErrors

func (c *Compiler) SetMaxErrors(limit int)

SetMaxErrors sets the limit on the number of errors that can happen before the compiler gives up.

func (*Compiler) SetUsePush0

func (c *Compiler) SetUsePush0(on bool)

SetUsePush0 enables/disables use of the PUSH0 instruction. It's on by default.

type Position

type Position struct {
	File string
	Line int
}

Position represents the position of an error in a file.

func (Position) String

func (p Position) String() string

type PositionError

type PositionError interface {
	error
	Position() Position
}

PositionError is an error containing a file position.
