Language.C.Data.Ident

Description

This module provides the notion of identifiers in C, speed up using hashing. Identifiers are associated optionally associated with a NodeInfo, i.e. with a unique Name and a source location (Position). The ordering relation on identifiers is based on the hash and does not follow the lexical order.

isAnonymousRef :: SUERef -> Bool Source #

Return true if the struct/union/enum reference is anonymous.

mkIdent :: Position -> String -> Name -> Ident Source #

build an identifier from a string.

  • only minimal error checking, e.g., the characters of the identifier are not checked for being alphanumerical only; the correct lexis of the identifier should be ensured by the caller, e.g., the scanner.
  • for reasons of simplicity the complete lexeme is hashed.

builtinIdent :: String -> Ident Source #

returns a builtin identifier (has builtin position and no unique name)

internalIdent :: String -> Ident Source #

returns an internal identifier (has internal position and no unique name)

internalIdentAt :: Position -> String -> Ident Source #

return an internal identifier with position info

isInternalIdent :: Ident -> Bool Source #

return True if the given identifier is internal

identToString :: Ident -> String Source #

string of an identifier

sueRefToString :: SUERef -> String Source #

string of a SUE ref (empty if anonymous)

dumpIdent :: Ident -> String Source #

dump the identifier string and its positions for debugging purposes
