This is the Haskell 2010 report, source distribution.  

This has all files needed to generate either the postscript or the
html version of the Haskell report.  Some of these files are generated
from others - these are marked with a (*) and are included in case the
tool used to generate the file is unavailable.

To generate the postscript report you need lex, perl, latex,
makeindex, and dvips.

To generate the html report you need Hugs 1.4 (probably any Haskell
1.4 compiler will do).

To change the date on the report, you must change:
	* haskell.verb (line 429-ish)
	* index.html (line 8-ish)
	* html.config (~foot item)
	

Source files for the report:
plain-haskell.verb  -- Top level of the report

Sections of the report:
intro.verb
lexemes.verb
exps.verb
decls.verb
modules.verb
basic.verb
io-13.verb
standard-prelude.verb
syntax-iso.verb
literate.verb
derived.verb
pragmas.verb
haskell.bib

Extra .verb files:
iso-chars.verb    -- Some bogus definitions for ISO chars.  Probably not 
                  -- needed since I removed them from the syntax. 
layout.verb       -- a section on layout repeated in the appendix
index-extra.verb  -- extra stuff to get indexed (see also's)
index-intro.verb  -- header for index

Haskell source files:

Prelude.hs
PreludeList.hs
PreludeIO.hs
PreludeText.hs

Figures:

classes.ppt       --  The original class figure (Powerpoint)
classes.eps (*)   --  Postscript version of class-fig
classes.gif (*)   --  For html version
cover.cdr         --  A nice looking cover for the report
cover.eps (*)

Html support:

html.config        -- configuration file for tex.hs.
haskell.aux (*)    -- The aux file generated by latex; used by html translator
haskell.bbl (*)    -- used by html translator.  Hand edited to add
                   -- html headers at front.
prelude-index.idx  -- Html file containing index of prelude.  #'s are
                   -- expanded by index.hs
index.html         -- Top level of the html report (hand generated)
lambda.gif         -- background for title page
title.gif          -- title graphic 

Other files:

Makefile         -- Lots of extra cruft no longer used. 
haskell.dvi (*)  -- in case you just want to run dvips
haskell.ind (*)  -- is case you don't have makeindex 
haskell.idx (*)  -- makes building easier


To build the .dvi you need to patch the makefile to call the proper
version of perl.  You will have some `non-grokked' instances in the
perl.  Remember that you have to run latex twice.  If anyone converts
the perl program to perl5 please send it to us!

Building HTML files
~~~~~~~~~~~~~~~~~~~
Build the html by creating a `html' subdirectory, copy the .html and
.gif files to it, and run tex.hs twice (like tex - to get forward refs
right).  Run index.hs to generate the function index.  You're done.
The 'make html' does most of this.

There are three files you need to work on:

	report/html.config

Edit the title in the headers and footers. 
You can hack in whatever html you want for page headers and
footers .  You can also hack on the output directory setting (htmldir)
to direct the output wherever you want.  You'll have to fiddle
"index.hs" if you do this, though.  You can also add the line

	style = microsoftsymbols,article

This exploits the symbol font that microsoft uses in its browser.
Much nicer for some of the equations.  Probably a good idea since most
browsers handle the symbol font OK nowadays.

	report/prelude-index.idx

You will need to edit this a little bit; probably just a few renamings
and deleting stuff that lives in the libraries now.  Add a few more 
examples if you're feeling energetic.

As to the building process:

To build the html report: (using the .aux file and all the .verb files) 

cd <report directory>
runhugs tex.hs
runhugs tex.hs
runhugs index.hs

Like latex, you have to run tex.hs twice.  Unless you make massive
changes, though, you can probably just do it once.  I'm sure ghc will
compile tex.hs if you want to speed things up. 



Making figures
~~~~~~~~~~~~~~
The classes.eps files, which contains the classes hierarchy figure,
is made in Powerpoint, from classses.ppt.  To get the .eps file,
do the following:

* Open classes.ppt
* Print..
* Check the print-to-file box, and save as classes.prn
* Edit classes.prn
	Kill the .prn header and footer (before % PS-Adobe), and after %EOF
	Kill the entire setup code (from BeginSetup to EndSetup)
	Kill the showpage near the end
* Save as classes.eps
* Open with Ghostview
* Note the coords of the bottom LH and top RH corner, as reported by
  Ghostview
* Re-edit classes.eps, and put those coords in the
	%BoundingBox line

You also need to do
	Save As.. 
in Powerpoint, and save the thing as classes.gif, for the HTML version
