Some time ago I put together a small BERT serializer and BERT-RPC client for .Net called Filbert (which is another name for Hazelnut, that has the word bert and the letter F and at the time every F# library has a leading F in its name!). As an experimental project admittedly I hadn’t given too …

I was recently invited to chat to the Mostly Erlang podcast about F#, with co-host Bryan Hunter, Fred Hebert (author of the excellent Learn You Some Erlang for Great Good!) and fellow F# addict Phil Trelford (author of many popular F# libraries such as TickSpec, Mini Rx and Foq).

Following on from my last post on formatting a Markdown document into PDF using FSharp.Markdown.Pdf, if you don’t like the default styling (which I tried to mimic style Github formats Markdown documents with) you can set your own styling for the different types of Markdown elements by going down a level of abstraction.
