Low-level "generic" signal creator for creating signals of any "kind".
|
|
Takes a single map of options [2] with compile-time keys.
|
|
|
|
Default kind: `:generic` (feel free to change!)
|
|
Default level: `:info`
|
|
Returns:
|
|
- If given `:run` form: unconditionally returns run value, or rethrows run error.
|
|
- Otherwise: returns true iff signal was created (allowed by filtering).
|
|
|
|
When filtering conditions are met [4], creates a Telemere signal [3] and
|
|
dispatches it to registered handlers for processing (e.g. writing to
|
|
console/file/queue/db, etc.).
|
|
|
|
Generic signals are fairly low-level and useful mostly for library authors or
|
|
advanced users writing their own wrapper macros. NB see `keep-callsite` for
|
|
preserving callsite coords when wrapping Telemere macros like `signal!`.
|
|
|
|
Regular users will typically prefer one of the higher-level signal creators
|
|
optimized for ease-of-use in common cases [1].
|
|
|
|
Tips:
|
|
|
|
- Test using `with-signal`: (with-signal (signal! ...)).
|
|
- Supports the same options [2] as other signals [1].
