The oak sleeps in the acorn

Introduction We launched Fantomas v5 in September, and it was the first version to ship with a custom F# parser and an improved syntax tree. Many view it as a big technical achievement – I know its launch was a point of personal pride. Release party Because version 5 was a big deal, I decided to organize a grand release party where we talked about how v5 came to be, what exactly changes for end-users and I wrapped it up with a well-deserved glass of champagne. The project is in a good state. We have a brand new documentation website, I onboarded a new co…

Intro Yesterday, pretty much out of nowhere, FCS 41.0.3 was published on NuGet. I must say, I’m pretty hyped about this release. It contains a few PRs that improve the syntax tree and provide more information to work within Fantomas. It also contains some XML documentation improvements that Alex of the Rider team has been working on. You can read the details about this new XML collecting mechanism in this RFC. It is a nice improvement and I’ve decided to implement an enhancement in Fantomas due to these changes. There actually are comments in the syntax…
