Description
Expected behavior
This code adds breakpoints wherever possible:
(defn repro
[x]
#dbg
[x])Actual behavior
When evaling above fn in a way that triggers the debugger machinery, the following exception is raised: "java.lang.RuntimeException Unable to resolve symbol: STATE__ in this context".
Workaround
Adding a do prevents the exception:
(defn repro
[x]
#dbg
(do [x]))Other details
The bug only occurs in this specific case where you have a vector literal with a closed-over local. Some examples of things that don't break:
- The local itself:
(defn works [x] #dbg x) - An empty vector:
(defn works [x] #dbg []) - A vector with a clojure.core name:
(defn works [x] #dbg [next]) - A set works:
(defn works [x] #dbg #{x}) - A map works, with the var as a key:
(defn works [x] #dbg {x :a})(breaks if it's in a value, though)
However, the bug also occurs when you close over e.g. a required name:
;; io is clojure.java.io
(defn breaks [x] #dbg [io/as-file])Steps to reproduce the problem
- Paste above code in a buffer
- C-M-x or C-x e it
