Exact lookup

1. glGetVaryingLocationNV :: MonadIO m => GLuint -> Ptr GLchar -> m GLint

   OpenGLRaw	Graphics.GL.NV.TransformFeedback

   No documentation available.

2. newtype MissingEnvironmentVariable

   dhall	Dhall.Import

   Exception thrown when an environment variable is missing

3. MissingEnvironmentVariable :: Text -> MissingEnvironmentVariable

   dhall	Dhall.Import

   No documentation available.

4. bashEnvironmentVariable :: Parser Text

   dhall	Dhall.Parser.Token

   Parse a valid Bash environment variable name This corresponds to the bash-environment-variable rule in the official grammar

5. posixEnvironmentVariable :: Parser Text

   dhall	Dhall.Parser.Token

   Parse a valid POSIX environment variable name, which permits a wider range of characters than a Bash environment variable name This corresponds to the posix-environment-variable rule in the official grammar

6. escapeEnvironmentVariable :: Text -> Text

   dhall	Dhall.Pretty

   Escape an environment variable if not a valid Bash environment variable

7. listVars :: Typeable a => String -> a -> [Expr]

   express	Data.Express

   Generate an infinite list of variables based on a template and a given type. (cf. listVarsAsTypeOf)

   > putL 10 $ listVars "x" (undefined :: Int)
   [ x :: Int
   , y :: Int
   , z :: Int
   , x' :: Int
   , y' :: Int
   , z' :: Int
   , x'' :: Int
   , ...
   ]
   

   > putL 10 $ listVars "p" (undefined :: Bool)
   [ p :: Bool
   , q :: Bool
   , r :: Bool
   , p' :: Bool
   , q' :: Bool
   , r' :: Bool
   , p'' :: Bool
   , ...
   ]
   

8. listVarsAsTypeOf :: String -> Expr -> [Expr]

   express	Data.Express

   Generate an infinite list of variables based on a template and the type of a given Expr. (cf. listVars)

   > let one = val (1::Int)
   > putL 10 $ "x" `listVarsAsTypeOf` one
   [ x :: Int
   , y :: Int
   , z :: Int
   , x' :: Int
   , ...
   ]
   

   > let false = val False
   > putL 10 $ "p" `listVarsAsTypeOf` false
   [ p :: Bool
   , q :: Bool
   , r :: Bool
   , p' :: Bool
   , ...
   ]
   

9. listVarsWith :: [Expr] -> Expr -> [Expr]

   express	Data.Express

   O(n+m). Like lookupNames but returns a list of variables encoded as Exprs.

10. listVars :: Typeable a => String -> a -> [Expr]

    express	Data.Express.Hole

    Generate an infinite list of variables based on a template and a given type. (cf. listVarsAsTypeOf)

    > putL 10 $ listVars "x" (undefined :: Int)
    [ x :: Int
    , y :: Int
    , z :: Int
    , x' :: Int
    , y' :: Int
    , z' :: Int
    , x'' :: Int
    , ...
    ]
    

    > putL 10 $ listVars "p" (undefined :: Bool)
    [ p :: Bool
    , q :: Bool
    , r :: Bool
    , p' :: Bool
    , q' :: Bool
    , r' :: Bool
    , p'' :: Bool
    , ...
    ]
