Functions

func PlatformIndependentPathDirBaseExt 

func PlatformIndependentPathDirBaseExt(path string) (dir string, base string, ext string)

This has a custom implementation instead of using "filepath.Dir/Base/Ext" because it should work the same on Unix and Windows. These names end up in the generated output and the generated output should not depend on the OS.

func PrintErrorToStderr 

func PrintErrorToStderr(osArgs []string, text string)

func PrintMessageToStderr 

func PrintMessageToStderr(osArgs []string, msg Msg)

func PrintText 

func PrintText(file *os.File, level LogLevel, osArgs []string, callback func(Colors) string)

	LevelWarning
	LevelError
	LevelSilent
)

type Msg 

type Msg struct {
	Kind  MsgKind
	Data  MsgData
	Notes []MsgData
}

func (Msg) String 

func (msg Msg) String(options StderrOptions, terminalInfo TerminalInfo) string

type MsgData 

type MsgData struct {
	Text     string
	Location *MsgLocation
}

func RangeData 

func RangeData(source *Source, r Range, text string) MsgData

type MsgDetail 

type MsgDetail struct {
	Path    string
	Line    int
	Column  int
	Message string

	SourceBefore string
	SourceMarked string
	SourceAfter  string

	Indent string
	Marker string

	ContentAfter string
}

type MsgKind 

type MsgKind uint8
const (
	Error MsgKind = iota
	Warning
	Note
)

func (MsgKind) String 

func (kind MsgKind) String() string

type MsgLocation 

type MsgLocation struct {
	File      string
	Namespace string
	Line      int // 1-based
	Column    int // 0-based, in bytes

}

func LocationOrNil 

func LocationOrNil(source *Source, r Range) *MsgLocation

type Path 

type Path struct {
	Text      string
	Namespace string
}

This is used to represent both file system paths (Namespace == "file") and abstract module paths (Namespace != "file"). Abstract module paths represent "virtual modules" when used for an input file and "package paths" when used to represent an external module.

func (Path) ComesBeforeInSortedOrder

	Len int32
}

type SortableMsgs []Msg

This type is just so we can use Go's native sort function

func (SortableMsgs) Len 

func (a SortableMsgs) Len() int

func (SortableMsgs) Less 

func (a SortableMsgs) Less(i int, j int) bool

func (SortableMsgs) Swap 

func (a SortableMsgs) Swap(i int, j int)

type Source 

type Source struct {
	Index uint32

	// This is used as a unique key to identify this source file. It should never
	// be shown to the user (e.g. never print this to the terminal).
	//
	// If it's marked as an absolute path, it's a platform-dependent path that
	// includes environment-specific things such as Windows backslash path
	// separators and potentially the user's home directory. Only use this for
	// passing to syscalls for reading and writing to the file system. Do not
	// include this in any output data.
	//
	// If it's marked as not an absolute path, it's an opaque string that is used
	// to refer to an automatically-generated module.
	KeyPath Path

	// This is used for error messages and the metadata JSON file.
	//
	// This is a mostly platform-independent path. It's relative to the current
	// working directory and always uses standard path separators. Use this for
	// referencing a file in all output data. These paths still use the original
	// case of the path so they may still work differently on file systems that
	// are case-insensitive vs. case-sensitive.
	PrettyPath string

	// An identifier that is mixed in to automatically-generated symbol names to
	// improve readability. For example, if the identifier is "util" then the
	// symbol for an "export default" statement will be called "util_default".
	IdentifierName string

	Contents string
}
