Readme for typeof-0.1.2

[back to package description] 
typeof: a script for inserting Haskell types in source code

== Building ==

    runhaskell Setup.lhs configure
    runhaskell Setup.lhs build
    runhaskell Setup.lhs install

== Use ==

The script accepts two inputs:
        
   command line argument 1: the file name to look in.
   stdin:                   the line containing the top level type
                                    declaration who's type you

the output is the type declaration for the value you requested, which
can be spliced back in to your source file.

VIM:

You can run the script from vim directly by adding the following to your
.vimrc file:
   
    :map ty yy:.!typeof -fbang-patterns %^Mp

Now, when you position your cursor over a top level declaration,
hitting:

    :ty

will insert the type declaration on the line above the one the cursor is
on.

EMACS:

In emacs add the following to your .emacs.el file:

(global-set-key (kbd "C-c t")
    (lambda () (interactive)
        (progn
            (save-buffer)
            (move-beginning-of-line nil)
            (call-process-region
                (line-beginning-position)
                (line-end-position)
                "typeof"
                nil
                t
                nil
                (buffer-file-name)))))

Then you can use C-c t to run insert the type declaration.
