Language.Futhark.Query

Description

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.

Synopsis

data BoundTo Source #

What a name is bound to.

Methods

showsPrec :: Int -> AtPos -> ShowS #

show :: AtPos -> String #

showList :: [AtPos] -> ShowS #

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.

data Pos #

Position type.

Constructors

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.
