Hi Michael, I have write some dynamic-loading code for my Manatee project (http://hackage.haskell.org/package/manatee)
Dynload.hs use GHC API, if you interested it, you can read source code: https://patch-tag.com/r/AndyStewart/manatee-core/snapshot/current/content/pretty/Manatee/Core/Dynload.hs Cheers, -- Andy Michael Snoyman <[email protected]> writes: > Hi Andy, > > plugins *is* working in general for me for some trivial test cases. > It's specifically this use case with WAI that's causing trouble, which > implies to me I'm misusing the API somehow. > > Michael > > On Tue, Feb 1, 2011 at 4:22 AM, Andy Stewart <[email protected]> > wrote: >> Hi Michael, >> >> plugins use it's own function instead GHC API, so it's easy to break >> with new version GHC. >> >> -- Andy >> >> Michael Snoyman <[email protected]> >> writes: >> >>> Hi all, >>> >>> I'm trying to convert wai-handler-devel to use plugins instead of >>> hint, but cannot even get some basic usages to work properly.
