Xmobar is a text-based, minimalistic status bar for linuxy systems,

Hi Jose,
Peter, would using parsec 3.x be an acceptable solution to you?
well, we can link xmobar with parsec 3.x on NixOS. The situation
is tricky, though, because the latest version of parsec that we
have, 3.1.2, doesn't compile with GHC 6.10.4 anymore, so we'd
have to use some older version

maybe we should look into ways of taking some of the work off Duncan.

Hi Antoine,
What errors are you getting compiling with GHC 6.10.4? If its a small
thing I certainly don't mind patching things.
I am sorry, my previous statement was inaccurate. Parsec 3.1.2 compiles
fine, but the 'text' library -- on which Parsec depends -- does not. We

* Default Generic implementation of Serial instance, contributed by Bas van Dijk
This means that you don't need to write instances by hand for your types
to generate test values for them. See [1]
It occurs to me that c2hs (or more appropriately the gtk2hsc2hs fork) is
intended to solve this problem; have you looked into it?
hdirect falls into this category as well

To clarify, by hack I meant that it seemed like a workaround specifically
to keep case in the OP's code, when it seemed like they were looking for
the functionality of guards.

The extra parameter i is for information attached to each node of the tree.
As you have correctly guessed, the parser fills in this field with positional
information relating to the original source document, which is useful for
instance if you are validating or checking the original document.
I suggest switching from 'read' to a real parser that can give you proper error
messages. I use Text.Parse from the polyparse package, which is designed to
parse back exactly the format produced by derived Show instances. To derive
the Parse class from your datatypes, the tool DRiFT is handy.
