Re: Plugins: How to determine ghc vs ghci

The executable-path package wraps this up nicely with its `getScriptPath` function: https://hackage.haskell.org/package/executable-path-0.0.3/docs/System-Enviro... Probably best to use this existing function. Then, if a less fragile solution comes along, getScriptPath can do that instead. -Michael On Tue, Nov 24, 2015 at 5:58 PM, Levent Erkok wrote:

Thanks! That indeed does work.

I'm a bit surprised though that there isn't already an internal boolean set somewhere; checking for a string in the arguments sounds a bit fragile.

How about `GHC.Environment.getFullArgs` which includes “—interactive” when you’re in GHCi?

I'm working on a plugin, and would like to be able to tell if it's GHC or GHCi that's running.

I tried:

df <- getDynFlags let isGHCi = ghcMode df == CompManager

Alas, while that correctly tells apart "ghci" from "ghc -c", it also returns True when ghc is called without the "-c" argument.

Is there a better/more robust way of figuring out whether we're in an interactive session?
