Parsing project.clj eval error

[brandonstubbs]

Hi

I am working on some OSS projects that are a mono-repo and the version is shared into the microservices. Below is an example project.clj

(defn ver [] "1.10.1") ; originally (defn ver [] (-> "../ver/project.version" slurp .trim)))
(defproject error "0.1.0-SNAPSHOT"
  :description "FIXME: write description"
  :url "http://example.com/FIXME"
  :license {:name "EPL-2.0 OR GPL-2.0-or-later WITH Classpath-exception-2.0"
            :url "https://www.eclipse.org/legal/epl-2.0/"}
  :dependencies [[org.clojure/clojure #=(ver)]]
  :repl-options {:init-ns error.core})

You won't be able to jack-in as the cljs.tools.reader library does not support read-eval
So you will get Error: read-eval not supported while trying to parse-forms

I propose to change the following parse.cljs#L36 to (let [pbr (rt/string-push-back-reader (str/replace s #"#=\(" "#_("))] ultimately ignoring the eval.

Please let me know if you are happy with this approach and I will open a PR for this change.

If this works for you it seems fine to change, but I don't know what other implications there could be (if it would affect parsing negatively in any scenarios, but likely not). I'll defer to @PEZ to decide.

@PEZ Please let me know your thoughts on the above thanks 😄

Yes, sorry for late response. This is pragmatic. It will work and will not break anything.

We should parse these files using the token cursor, but for now, this change is super.
