1.)
I know I can use
Build-Depends: lib == <version>, lib2 < version, lib3 >=
version
and so on.
Do you think it would be useful to introducue some notation to indicate
a "tested with" ?
Reason, purpose: I think its sometimes the case that a author/ mantainer
is quite busy with other projects and misses that some dependencies
break things.. If you want to try out you're left with some compiler
errors and a dependency and have to try out which version works.
I would propose using this syntax:
lib-1.3 >=1.1
to indicate that lib 1.1 is required at leeast and tested with up to
1.3.. Cabal might then give a warning if you try to use 1.4 or greater
"using newer version than tested" or similar..
What do you think?
Would this be useful?
2.)
Is there a ghci target?
I find it quite useful using ghci to debug test/ check types
functions of single modules...
My hack is using a Setup.hs file like this adding ./setup ghci
which runs ghci and adds all dependency as -pakcage arguments:
module Main where
import Distribution.Simple
import Distribution.Simple.Configure
import System
import System.Process
import System.Exit
import Monad
main= do
args <- getArgs -- check args to launch ghci
when (length args > 0) $ do
when ((args!!0) == "ghci") $ do
lbi <- getPersistBuildConfig
let packageArgs = (concat.concat) [ [" -package ",
showPackageId pkg] | pkg <- packageDeps lbi ]
system("ghci " ++ packageArgs)
exitWith ExitSuccess
defaultMain -- fallback to defaultMain
Would this be useful for you, too?
