Greater customization of GHCi prompt
This patch is trying to redesign the :set prompt option to take not a
String but a Haskell function, like [String] -> Int -> IO String, where
[String] is the list of the names of the currently loaded modules and
Int is the line number. Currently you may set prompt function with
**:set promt-function [String] -> Int -> IO String** option and old
version is also available - :set prompt String.
So, it looks like I've almost completed this patch:
1) Now we have a lot of escape sequences - 13 to be exact. Most of them
are similar to bash prompt escape sequences. Thus they are quite handy.
2) We may use the special escape sequence to call shell functions, for
example "%call(ls -l -a)".
3) We may use :set prompt-function to set PFunction to handle prompt.
It is just [String] -> Int -> IO String.
