Hi everyone - I'm a relative newcomer to Haskell, and am very much besotted with it - it's a great language! :-) At the moment, I'm in the early stages of putting together a little "Haskell-like" language using the Spirit parser framework (Spirit is part of the Boost C++ libraries). Spirit also has a functional-programming "sister" library (Phoenix), which includes lambdas, lazy functions and lots more. Phoenix is currently being merged with the Boost Lambda Library. ( Sorry for the off-topic digression - just giving the background to what I'm doing .... ;-) ) I've done a couple of "toy parsers" for Spirit already, but now I'm looking to do something that is more of a challenge - doing a small-ish Haskell-like language. The language is aimed at being able to read in a comma-delimited file (with column-headings), and putting the data into "columns". ( I envisage maybe a Haskell "pair". The first item being the column heading, the second being a list, with the data in it. ) Then, the user would select one of those "columns" for a "page" variable (that one would be optional), and one or more "columns" for the crosstab rows and columns. What I'm needing to do is to first put together the code in Haskell itself, and get it running. Then, that will give me a good feel as to how much of "core" Haskell I need to implement, in order to do the crosstab app. So, I was wondering - has anyone in the Haskell community used Haskell to do crosstabs? ( And if so, is there any code available? ). Any help in the two areas - a) Using Haskell to read a delimited file (with column-headings) into a columnar or tabular data-structure - b) Using Haskell to do crosstabs - - would be very welcome! I should also stress that full credit will be given to the writers of any code supplied. Very many thanks in advance for any help received! - - Andy
