Facilities for answering queries about a program, such as "what appears at this source location", or "where is this name bound". The intent is that this is used as a building block for IDE-like functionality.
Documentation
What a name is bound to.
boundLoc :: BoundTo -> Loc Source #
Where was a bound variable actually bound? That is, what is the location of its definition?
Information about what is at the given source location.
atPos :: Imports -> Pos -> Maybe AtPos Source #
Information about what's at the given source position. Returns
Nothing
if there is nothing there, including if the source
position is invalid.
Position type.
Pos !FilePath !Int !Int !Int | Source file name, line, column, and character offset. Line numbering starts at 1, column offset starts at 1, and character offset starts at 0. |
