Functions ¶
func WriteListing ¶
WriteListing prints the generated bytes next to the original source, ie an assembly listing.
Types ¶
type BytesLiteral ¶
type BytesLiteral struct {
// contains filtered or unexported fields
}
type CharLiteral ¶
type CharLiteral struct {
// contains filtered or unexported fields
}
type DefineByteStatement ¶
type DefineByteStatement struct {
Node
// contains filtered or unexported fields
}
type DefineSpaceStatement ¶
type DefineSpaceStatement struct {
Node
// contains filtered or unexported fields
}
type DefineWordStatement ¶
type DefineWordStatement struct {
Node
// contains filtered or unexported fields
}
type EquateStatement ¶
type EquateStatement struct {
Node
// contains filtered or unexported fields
}
type ExprBinary ¶
type ExprBinary struct {
// contains filtered or unexported fields
}
type ExprUnary ¶
type ExprUnary struct {
// contains filtered or unexported fields
}
ExprUnary is a unary operation (+, -) on an expression.
type FunctionStatement ¶
type FunctionStatement struct {
Node
// contains filtered or unexported fields
}
type ImportStatement ¶
type ImportStatement struct {
Node
// contains filtered or unexported fields
}
type Input ¶
type Input struct {
// contains filtered or unexported fields
}
Input implements TokenReader but delegates to a list of underlying TokenReaders, reading each in order until EOF and then moving to the next. Copied from Go's asm/lexer/stack except this one is in order rather than stack based. Need it in order because the first source file will establish the org, all others must be libraries with relocatable code.
func NewInput ¶
func NewInput(readers []TokenReader) *Input
func (*Input) Append ¶
func (i *Input) Append(r TokenReader)
type InstructionStatement ¶
type InstructionStatement struct {
Node
// contains filtered or unexported fields
}
type IntLiteral ¶
type IntLiteral struct {
// contains filtered or unexported fields
}
type LabelStatement ¶
type LabelStatement struct {
Node
// contains filtered or unexported fields
}
type Linker ¶
type Linker struct {
// contains filtered or unexported fields
}
func (*Linker) Link ¶
func (l *Linker) Link()
Link uses two passes to try to resolve all references and generate code into l.code.
func (*Linker) PrintMessages ¶
func (l *Linker) PrintMessages()
type Message ¶
type Message struct {
// contains filtered or unexported fields
}
Message describes a compiler error, warning, or informational message.
type Messages ¶
type Messages struct {
// contains filtered or unexported fields
}
Messages is a collection of compiler messages.
func (*Messages) AddMessage ¶
type Node ¶
type Node struct {
// contains filtered or unexported fields
}
Node defines the common fields that all statements share.
func (*Node) BlockComment ¶
func (*Node) EolComment ¶
func (*Node) NewlineBefore ¶
func (*Node) SetBlockComment ¶
func (*Node) SetEolComment ¶
func (*Node) SetNewlineBefore ¶
func (*Node) SetPcStart ¶
type OrgStatement ¶
type OrgStatement struct {
Node
// contains filtered or unexported fields
}
type Parser ¶
type Parser struct {
// contains filtered or unexported fields
}
func (*Parser) PrintErrors ¶
func (p *Parser) PrintErrors()
func (*Parser) SetProcessImport ¶
func (*Parser) Statements ¶
type Printer ¶
type Printer struct {
// contains filtered or unexported fields
}
Printer pretty-prints statements to a writer.
func NewPrinter ¶
type Source ¶
type Source struct {
// contains filtered or unexported fields
}
Source represents a source file and the current state of lexing it.
func (*Source) GetTokenImage ¶
GetTokenImage gets the marked token as a string.
func (*Source) MarkEnd ¶
func (s *Source) MarkEnd()
MarkEnd sets the last read character as the end of the current token.
type Statement ¶
type Statement interface {
Next() Statement
SetNext(next Statement)
File() string
SetFile(file string)
Line() int
SetLine(line int)
NewlineBefore() bool
SetNewlineBefore(newlineBefore bool)
BlockComment() []string
SetBlockComment(blockComment []string)
EolComment() string
SetEolComment(eolComment string)
PcStart() int
SetPcStart(pcStart int)
PcEnd() int
SetPcEnd(pcEnd int)
}
Statement is an interface of Node just so all my types can implement the same interface?
type SymbolTable ¶
type SymbolTable struct {
// contains filtered or unexported fields
}
func NewSymbolTable ¶
func NewSymbolTable() *SymbolTable
func (*SymbolTable) AddFpSymbol ¶
func (s *SymbolTable) AddFpSymbol(file string, line int, text string, offset int)
func (*SymbolTable) Define ¶
func (s *SymbolTable) Define(text string, value int)
func (*SymbolTable) GetSymbol ¶
func (s *SymbolTable) GetSymbol(text string) *Symbol
type TokenReader ¶
