This is the input-side change related to [1], and only
affects folks who've been providing custom callsite info to
Telemere signals (usually in the context of wrapper macros).
To provide custom callsite info BEFORE this commit:
(tel/signal! {:location {:ns "my-ns", :line 10, :column 20}})
To provide custom callsite info AFTER this commit:
(tel/signal! {:ns "my-ns", :coords [10 20]})
Motivation for the new override API:
- It's shorter and cleaner.
- It's less likely to cause confusion since it avoids the
redundant signal keys (signals previously contained callsite
info in 2 duplicate places).
- The underlying implementation is simpler.
- The util for manually getting coords is easier to use and doesn't
require macro-time environment info, making it easier for folks
to write wrapper macros that include line + column info.
- When embedded, the new callsite info is shorter and easier for
Cljs advanced compilation to de-duplicate (so helps reduce .js
build size).
