This routine must be instantiated with an appropriate array 36-- element type, which must represent a character encoding in which the 37-- codes for ASCII characters in the range 16#20#..16#7F# have their normal 38-- expected encoding values (e.g. the Pos value 16#31# must be digit 1). 39 40pragma Compiler_Unit_Warning; 41 42package GNAT.Spelling_Checker_Generic is 43 pragma Pure; 44 45 generic 46 type Char_Type is (<>); 47 -- See above for restrictions on what types can be used here 48 49 type String_Type is array (Positive range <>) of Char_Type; 50 51 function Is_Bad_Spelling_Of 52 (Found : String_Type; 53 Expect : String_Type) return Boolean; 54 -- Determines if the string Found is a plausible misspelling of the string 55 -- Expect. Returns True for an exact match or a probably misspelling, False 56 -- if no near match is detected. This routine is case sensitive, so the 57 -- caller should fold both strings to get a case insensitive match if the 58 -- character encoding represents upper/lower case. 59 -- 60 -- Note: the spec of this routine is deliberately rather vague. This 61 -- routine is the one used by GNAT itself to detect misspelled keywords 62 -- and identifiers, and is heuristically adjusted to be appropriate to 63 -- this usage. It will work well in any similar case of named entities. 64 65end GNAT.Spelling_Checker_Generic; 66
