FileLoc

src @Js const class FileLoc : Obj

FileLoc is a location within a text file or source string. It includes an optional one-base line number and column number. This class provides a standardized API for text based tools which need to report the line/column numbers of errors.

constructors

make	Constructor for filename string
makeFile	Constructor for file

fields

col	One based line column number or zero if unknown
file	Filename location
inputs	Constant for tool input location
line	One based line number or zero if unknown
synthetic	Constant for synthetic location
unknown	Constant for an unknown location

methods

compare	Comparison operator
equals	Equality operator
hash	Hash code
isUnknown	Is this the unknown location
toStr	Return string representation as "file", "file(line)", or "file(line,col)".

Slot Details

col

src const Int col

One based line column number or zero if unknown

compare

src virtual override Int compare(Obj that)

Comparison operator

equals

src virtual override Bool equals(Obj? that)

Equality operator

file

hash

src virtual override Int hash()

Hash code

inputs

src const static FileLoc inputs := FileLoc.make("inputs", 0)

Constant for tool input location

isUnknown

src Bool isUnknown()

Is this the unknown location

line

src const Int line

One based line number or zero if unknown

make

src new make(Str file, Int line := 0, Int col := 0)

Constructor for filename string

makeFile
