Fixity information to give the parser so that infix operators can be parsed properly.
Operator fixities are represented by their associativity (left, right or none) and their precedence (0-9).
Eq FixityDefined in haskell-src-exts-1.24.0 · Language.Haskell.Exts.FixityData FixityDefined in haskell-src-exts-1.24.0 · Language.Haskell.Exts.FixityOrd FixityDefined in haskell-src-exts-1.24.0 · Language.Haskell.Exts.FixityShow FixityDefined in haskell-src-exts-1.24.0 · Language.Haskell.Exts.FixityThe following three functions all create lists of fixities from textual representations of operators. The intended usage is e.g.
fixs = infixr_ 0 ["$","$!","`seq`"]Note that the operators are expected as you would write them infix, i.e. with ` characters surrounding varid operators, and varsym operators written as is.
All fixities defined in the Prelude.
All fixities defined in the base package.
Note that the +++ operator appears in both Control.Arrows and
Text.ParserCombinators.ReadP. The listed precedence for +++ in
this list is that of Control.Arrows.
All AST elements that may include expressions which in turn may need fixity tweaking will be instances of this class.
applyFixities :: MonadFail m => [Fixity] -> ast SrcSpanInfo -> m (ast SrcSpanInfo)Tweak any expressions in the element to account for the fixities given. Assumes that all operator expressions are fully left associative chains to begin with.
