Thanks for the information.
Ok, from the example, it looks like ghci is significantly smaller than
the source in ghc-6.10.1/compiler/ghci directory. Hopefully my next
changes (if any at all) will not need more than a custom ghci. The test
I did needed also ghc change. The type of function GHC.resume changed from:
/resume :: GhcMonad m => SingleStep -> m RunResult/
/resume :: GhcMonad m => (SrcSpan->Bool) -> SingleStep -> m RunResult/
... plus the corresponding implementation change.
The added argument is a filtering function to limit source spans which
can recorded in the trace history. I'll post more when I know how it
changes my debugging experience.
