documentation - Where can I find the docs for Haskell's GHC.* modules? -

-

i'm trying understand how haskell package chesshs implemented. chess board represented ghc.arr.array, found out in ghci:

prelude chess> :i board data board   = board {turn :: color,            castlingavail :: string,            enpassant :: maybe (int, int),            board :: ghc.arr.array (int, int) (maybe piece)}     -- defined in ‘chess’ instance eq board -- defined in ‘chess’ instance show board -- defined in ‘chess’ prelude chess>

by googling found out ghc.arr module part of "base" package. found documentation of package on https://hackage.haskell.org/package/base

however, on page many hyperlinks various ghc.* modules not clickable. why not? can find documentation of these modules? in general, what's best way access arbitrary module's documentation?

(i tried searching hoogle "ghc.arr" , "ghc.arr.array", didn't return relevant)

functions ghc.* modules should in cases not used directly. reexported more user-friendly packages or modules. in example, documentation arrays can found in array package.

if not help, can directly @ source, contain documentation comments too. source code of ghc , base library mirrored github, source ghc.arr here.

the source code shows why ghc.arr module not clickable in base package documentation: line 3 of ghc/arr.hs contains following pragma:

{-# options_haddock hide #-}

so module intentionally hidden, since it's internal module not meant general usage.

python - Pygame screen.blit not working -

in program creating in python/pygame, screen.blit not working. in other programs have made, screen.blit works. error: traceback (most recent call last): file "c:...\main.py", line 46, in <module> screen.blit(sight.image, sight.rect) attributeerror: 'int' object has no attribute 'blit' the error in question caused screen variable being allocated integer instead of pygame.surface() object.perhaps accidentally rewrote variable somewhere? from can make of doing, seems stating position of blit full rect instead of coordinate. when do: screen.blit(sight.image,sight.rect) what program seeing is: screen.blit(sight.image,(sight.rect.x,sight.rect.y,sight.rect.width,sight.rect.height)) i assuming don't intend this. remember rect object consists of position, width , height. to correct code, put (sight.rect.x,sight.rect.y) location goes instead this: screen.blit(sight.image,(sight.rect.x,sight.rect.y)) the .x , .y corres
