refreshing namespaces breaks *data-readers*
View data-readers.md

If you call clojure.tools.namespace.repl/refresh before requiring any namespaces referenced in data_readers.clj, then *data-readers* gets messed up somehow. The readers you define in data_readers.clj won't work even if you require their namespaces. For example:

$ find -type f
./src/foo/core.clj
./src/data_readers.clj
./src/user.clj

tools.deps bug with :local/root?
View local-root.md

On a project I'm working on, this gives me an error:

$ clj -Sdeps '{:deps {trident/build {:local/root "/home/arch/dev/trident/target/build"}}}' \
>     -m trident.build reset
Exception in thread "main" Syntax error compiling at (trident/build/util.clj:1:1).
...
Caused by: java.lang.ClassNotFoundException: jnr.posix.POSIXFactory
...

(I have (:import (jnr.posix POSIXFactory))) in that file).

You can’t perform that action at this time.
