analyze-causeclj

(analyze-cause e print-fn)

Return a map describing the exception cause. If ex-data exists, a :data key is appended.

Return a map describing the exception cause. If `ex-data` exists, a `:data`
key is appended.

analyze-causesclj

(analyze-causes e print-fn)

Return the cause chain beginning with the thrown exception, with stack frames for each. For ex-info exceptions response contains :data slot with pretty printed data. For clojure.spec asserts, :spec slot contains a map of pretty printed components describing spec failures.

analyze-fileclj

(analyze-file {:keys [file] :as frame})

Associate the file type (extension) of the source file to the frame map, and add it as a flag. If the name is NO_SOURCE_FILE, type clj is assumed.

analyze-fnclj

(analyze-fn {:keys [file type class method] :as frame})

Add namespace, fn, and var to the frame map when the source is a Clojure function.

extract-locationclj

(extract-location {:keys [class message location] :as cause})

If the cause is a compiler exception, extract the useful location information from its message or from :location if provided. Include relative path for simpler reporting.

(filtered-ex-data e)

Same as ex-data, but filters out entries whose keys are blacklisted (generally for containing data not intended for reading by a human).

flag-duplicatesclj

(flag-duplicates frames)

Where a parent and child frame represent substantially the same source location, flag the parent as a duplicate.

flag-projectclj

(flag-project {:keys [ns] :as frame})

Flag the frame if it is from the users project. From a users project means that the namespace is one we have identified or it begins with the identified common prefix.

flag-toolingclj

(flag-tooling frames)

Walk the call stack from top to bottom, flagging frames below the first call to clojure.lang.Compiler or nrepl.* as :tooling to distinguish compilation and nREPL middleware frames from user code.
