Methods
panicComponentName :: a -> String Source #
Name of the panicing component.
panicComponentIssues :: a -> String Source #
Issue tracker for the panicking component.
panicComponentRevision :: a -> (String, String) Source #
Information about the component's revision. (commit hash, branch info)
useGitRevision :: Q Exp Source #
An expression of type a -> (String,String).
Uses template Haskell to query Git for the current state of the repo.
Note that the state reported depends on when the module containing
the splice was compiled.
type HasCallStack = ?callStack :: CallStack #
Request a CallStack.
NOTE: The implicit parameter ?callStack :: CallStack is an
implementation detail and should not be considered part of the
CallStack API, we may decide to change the implementation in the
future.
Since: base-4.9.0.0
Arguments
| :: (PanicComponent a, HasCallStack) | |
