Is this expected behavior with meta data?

Why doesn't this work? user=> (meta ^{:some-meta 123} 'n) nil While this works: user=> (meta ^{:some-meta 123} (fn [n] n)) {:some-meta 123} And this works too: user=> (meta (with-meta 'n {:some-meta 123})) {:some-meta 123} Is this intended behavior? If so, what's the reasoning? Thanks, Sarki

Changing default clojure reader

Hello, Is it possible to change the default clojure reader to use clojure.tools.reader.reader-types/source-logging-push-back-reader? I am currently using this reader so that I can see the source code of my fns at runtime as metadata, however, it requires that I read the source again once the p

*data-readers* with clojure.tools.reader -- No reader function for tag id

Hi everyone, I am trying to use clojure.tools.reader to read from a file and also process datomic #db/id literals, but I am not sure how to pass in the *data-readers*? clojure.tools.reader.edn allows something like this: (edn/read reader false eof { :readers *data-readers* } ) Is there somethi

Best way to create a namespace at runtime from a web app

Hi everyone, I am working on a web app that allows code and namespace creation at runtime, but I get an error when trying to create a namespace from a web process: java.lang.IllegalStateException: Can't change/establish root binding of: *ns* with set This works when doing in a repl or single t

possible to preserve formatting info with read-string?

Hey guys, Is there a similar function to read-string that preserves formatting info (perhaps by storing formatting info as metadata)? My app does a read-string on a clojure file and saves the content to datomic (each fn is stored in an entity, each file can have multiple fns). The difficulty t
