Weave is the Programming Language I’ve been developing in my spare time. …If you’ve been reading my blog at all, you’ll know that already. As I’ve been working on making Weave more of a “Real” language I realized I needed to provide some sort of error handling mechanism. While functions are pure and beautiful, we live in a world where side effects and muck are not only expected, but often required to Get Things Done. [Read More]

One line convert from CSV to JSON read("input.csv", :csv) |> ^(rows) { write("output.json", rows, :json) } First class Lambdas & pipe operations make for easy function composition We can put generically useful logic inside reusable module, not reinvented for each script.

I recently re-read my original post about Weave - the data-pipeline language I’ve been developing in my spare time.

(Pssst - wanna jump to the Syntax?) I’ve long enjoyed learning programming languages and I try to learn at least one new language every year.

It’s long held a fascination for me, with its legendary expressive flexibility and unusual syntax (at least, by C-family standards)! [Read More]
