Return the log of a task, if enabled.
task_log(id, root, parse = TRUE)Single task identifier
A context root (not just the db as in
task_result as we need to know the actual path to
the root). A context object is also OK.
Parse the log output into a context_log
object, which will pretty print and can be more easily
inspected. If FALSE then the raw log will be returned as
a character vector, one element per line of text
The returned object is of class task_log, which has a print
method that will nicely display. Output is grouped into phases.
