I spent some of my time at Recurse Center (formerly Hacker School)
getting hands-on with Clojure. I wrote five blog posts. The first of
the series is here:

This is a bit of an anecdote:
I've started doing some Clojure and ClojureScript tutorials; the idea being to
learn enough ClojureScript to use it with reactjs wrappers on the front-end.
So far the experience has been quite pleasant, with my brain wrapping itself
around a #lang racket "cousin",
Does this change the default extension for #lang at-exp racket too?
Because that would be more confusing.
If I want to use at-expressions in a normal racket file, I don’t want it to set
the default extension to .scrbl.

Very close, thank you. The optional #:external-root-url argument turns it

A while back, Lei Wang implemented an indentation mode for Scribble
and it has been set up in the implementation of the reflow-paragraph
keybinding (alt-q / meta-q) but it hadn't been set up for indentation.
I've now done that and sorry for the long delay. (The latest snapshots

This seems straightforward but I'm getting lost in the weeds: what's the
simplest way to generate hyperlinks into Scribble docs on the web (without
having to manually copy the URL)?
For instance, the URL for `map` looks like this:

You can use ~and to bind it to an attribute.

Thanks Robby and Matthew. I use relative or runtime-computed paths myself
so it looks like everything is clear. I do need to consider how to manage
different Racket builds, right now I have stuck with the same build but
updating Racket is something I will need to manage.

Unfortunately, I don't think there's an easy way to fix this in 6.1.1.
That program works in current snapshots, so you might try that.
Alternatively, you could put the namespace anchor in an untyped
module, although that can be inconvenient for namespace anchors in
particular.

Thank you Matthias
This suggestion has enlightened me.
I did not figure out a good way to filter tests based on their types.

I have a makefile.rkt to help me (and potential cooperators) build the

That's the --submodule or -s flag.
I did `raco help test` just now and discovered even more options than
I remembered. Including fun things like running tests in parallel,
