Modified files:
ghc/compiler/ghci InteractiveUI.hs
ghc/compiler/main DriverFlags.hs DriverState.hs Main.hs
ghc/compiler/parser Lex.lhs
Log:
Add a new command-line flag -e EXPR, which runs ghc in interactive
mode and evaluates EXPR only before exiting.
Also, the lexer now ignores lines beginning with "#!". This is so
that we can use ghc as a scripting language with Unix-style scripts
beginning with
#! /usr/local/bin/ghc -e main
(well, it's not quite that simple, but I'll leave the details for the
more enterprising hackers).
