Documentation

data Source Source #

Information about Prosidy source file.

The Show instance for ths class does not include the LineMap or Text fields, as those are rather noisy.

Constructors

Source

Fields

sourceName :: String
The reported file-name of the Source.
When read from file handles, a non-filepath description such as "<stdin>" is typically chosen. This field doesn't have semantic meaning, and should only be used to enrich the output displayed to users.
sourceText :: Text
The full source, as Text.
sourceLineMap :: LineMap
A mapping of the start position of each line in the Source.

locationSource :: Location -> Source Source #

The Source this location references.

locationColumn :: Location -> Column Source #

The column number in the Source.

locationLine :: Location -> Line Source #

The line number in the Source.

locationOffset :: Location -> Offset Source #

The position in the Source, counted by Unicode codepoints.

makeSource :: String -> Text -> Source Source #

Create a Source from a descriptive name and a body. The source name is typically a FilePath, but this is not guarenteed. For instance, when read from standard-input, Prosidy chooses to name the source <stdin>.

getSourceLine :: Line -> Source -> Maybe Text Source #

Fetch a single line from a source.

getLocation :: Offset -> Source -> Maybe Location Source #

Convert an Offset into a Location.

enrichLocation :: SparseLocation -> Location Source #

Add lazily computed line and column number information to a SparseLocation.

stripLocation :: Location -> SparseLocation Source #

Remove line and column number information from a Location.

lineOffsets :: LineMap -> [Offset] Source #

Convert a LineMap into a list of Offsets, corresponding to the first character of a line. Note that the initial offset is omitted-- the offset at index 0 will be the offset of the second line.

lineToOffset :: Line -> LineMap -> Maybe Offset Source #

Fetch the Offset for the given Line. Evaluates to Nothing if the given Line does not appear in the LineMap

offsetToLine :: Offset -> LineMap -> Line Source #

Fetch the Line number for a given Offset. Newlines will be attributed the line that they terminate, rather than the line started immediately afterwards.
