I had similar problems.
As far as I understand it, one would have to first add a config option for
passing GHC RTS arguments to Dyre library that Yi uses for configuration
management.
Then one can add all ghc compilation options to ghcOptions in
src/library/Yi/Main.hs, and RTS options to Dyre launch parameters.
--- a/yi/src/library/Yi/Main.hs
+++ b/yi/src/library/Yi/Main.hs
@@ -60,7 +60,7 @@ data ConsoleConfig =
defaultConsoleConfig :: ConsoleConfig
defaultConsoleConfig =
ConsoleConfig {
- ghcOptions = [],
+ ghcOptions = ["-auto-all", "-prof", "-osuf=p_o",
"-hisuf=p_hi", "-rtsopts"],
selfCheck = False
}
The issue is that runtime system parameters are normally invisible to
Haskell programs, and thus they do not get forwarded by Dyre when Yi real
"main" is relaunched.
So probably one can have two issues to open:
1. Against GHC: access runtime system parameters or command line arguments
before RTS processing.
2. Against Dyre: add runtime parameters, or just arbitrary parameters to be
forwarded during program relaunch.
