Types

type CodeError

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

CodeError represents problems in code which are fatal for a compiler.

func NewCodeError

func NewCodeError(location *utils.CodePartLocation, code ErrorCode,
	ctx []interface{}) *CodeError

NewCodeError allocates and initializes CodeError struct.

type CodeProblem

type CodeProblem interface {
	// contains filtered or unexported methods
}

CodeProblem represents a warning or error in source code.

type CodeWarning

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

CodeWarnings represents problems in code which are not that fatal for a compiler.

type Diagnostics

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

Diagnostics stores list of problems in source code to then print them when required.

func NewDiagnostics

func NewDiagnostics() *Diagnostics

NewDiagnostics initializes Diagnostics struct will empty list of problems.

func (*Diagnostics) AddError

func (d *Diagnostics) AddError(error *CodeError)

AddError adds code error to the list of problems in source code.

func (*Diagnostics) AddWarning

func (d *Diagnostics) AddWarning(warning *CodeWarning)

AddWarning adds code warning to the list of problems in source code.

func (*Diagnostics) PrintProblems

func (d *Diagnostics) PrintProblems()

PrintProblems prints out all code problems in source code.

type ErrorCode

type ErrorCode int

ErrorCode is code corresponding to a specific kind of error.

type WarningCode

type WarningCode int

WarningCode is code corresponding to a specific kind of warning in source code.
