How can I use --flag with repl command?

[jeiea]

I checked stack repl --flag package:flag works on stack v1.1.0, but now it seems that v1.3.2 reject it as invalid flag.
What's an alternative to this?

Seems to have moved over to stack build?

[jeiea]

Then, should I use `stack build --flag PACKAGE:FLAG --exec "ghci Main.hs"?
Is there any reason of moving?

[borsboom]

There was a significant refactoring of build arguments a while back (in order to support including build arguments in stack.yaml) and it's possible this was removed from stack repl by accident.

I've just bisected and found the commit 3347bcb. But I can't determine whether it is intended.

/cc @mgsloan?

Hmm, yes, that was an unintended consequence of that change. Most of the things in BuildOptsCLI aren't useful for ghci, but --flag and --ghc-options are, so I've added just those ones back in.
