[ruby-core:104364] [Ruby master Bug#14889] TracePoint for :line never seems to trigger on argument list. Maybe by design?

ruby-core #104364
Issue #14889 has been updated by jeremyevans0 (Jeremy Evans). This is basically the same issue as #15634. The default argument evaluation is not considered a separate expression, so no line event is generated. If you force it to use a separate expression by wrapping in parentheses, you can get a line event, as @mame demonstrated. Note that when not using a separate expression, the `coverage` shows a nil for the line. If you force a separate expression and line, the `coverage` library can tell if the line was covered or not. ---------------------------------------- Bug #14889: TracePoint for :line never seems to trigger on argument list. Maybe by design? https://bugs.ruby-lang.org/issues/14889#change-92596 * Author: ioquatix (Samuel Williams) * Status: Open * Priority: Normal * Backport: 2.3: UNKNOWN, 2.4: UNKNOWN, 2.5: UNKNOWN ---------------------------------------- I have the following code. ``` 30 1| def print_summary( 31 0| output = $stdout 32 | ) ``` In the margin is the line number followed by the number of hits according to `:line` trace point. I feel like line 31 should also trigger a line trace point. It's an argument, but it must be executed. Maybe a different trace point? `:argument`? -- https://bugs.ruby-lang.org/ Unsubscribe: <mailto:ruby-core-request@ruby-lang.org?subject=unsubscribe> <http://lists.ruby-lang.org/cgi-bin/mailman/options/ruby-core>
