clojurescript - 在运行时在 clojurescript 中添加类路径？

Question

是否可以在运行时在 Nodejs 上运行的 Clojurescript 程序中添加类路径？

Answer 1

假设您指的是在开发时修改基于节点的 REPL 的类路径，也许如果add-lib成为一个东西，那么这将很容易做到。这是一个实验，展示add-lib了在修订版的 ClojureScript 中使用动态修改类路径并加载（动态获取的）库：

deps.edn：

{:deps {org.clojure/clojurescript {:git/url "https://github.com/mfikes/clojurescript"
                                   :sha "4fa9edd736d47b8ef5648b61b199e64ef80735bb"}
        org.clojure/tools.deps.alpha {:git/url "https://github.com/clojure/tools.deps.alpha.git"
                                      :sha "d492e97259c013ba401c5238842cd3445839d020"}}}

使用它：

$ clj -m cljs.main -re node
cljs.user=> (require '[cljs.repl :refer [add-lib]])
nil
cljs.user=> (add-lib 'spec-provider {:mvn/version "0.4.14"})

true
cljs.user=> (require '[spec-provider.provider :as sp])
nil
cljs.user=> (sp/infer-specs
 [{:a 8  :b "foo" :c :k}
  {:a 10 :b "bar" :c "k"}
  {:a 1  :b "baz" :c "k"}]
 :toy/small-map)
((cljs.spec.alpha/def :toy/c (cljs.spec.alpha/or :keyword cljs.core/keyword? :string cljs.core/string?)) (cljs.spec.alpha/def :toy/b cljs.core/string?) (cljs.spec.alpha/def :toy/a cljs.core/integer?) (cljs.spec.alpha/def :toy/small-map (cljs.spec.alpha/keys :req-un [:toy/a :toy/b :toy/c])))
