From: shevegen@... Date: 2018-07-01T15:59:59+00:00 Subject: [ruby-core:87732] [Ruby trunk Bug#14889] TracePoint for :line never seems to trigger on argument list. Maybe by design? Issue #14889 has been updated by shevegen (Robert A. Heiler). I don't have anything overly helpful to the discussion to add; but I wanted to add one thing to this: > We usually write an optional argument in a line: def print_summary(out = $stdout) While I concur in general, I myself have experimented a little with layout such as: def foo( a = 'foo', b = 'bar', ) The reason was primarily because it is, for my bad eyesight, easier to assess which arguments are used; I only have to look at the left hand side mostly. Makes it easier for me to keep track what is going on. This may be a rare layout perhaps, but coming from this, I understand where Samuel is coming from (but this is not me saying anything pro or con on the suggestion itself; I really only wanted to comment on spaced-out optional arguments). On a side note that may not be very relevant either, one can add strings to ')' such as: def foo( i = 'bar' )"hello world!" puts i end foo :-) I don't even know if that is a bug or a feature or something totally irrelevant. I just found it funny and golfing-worthy (even though I am a horrible code golfer). Almost a bit like python doc strings! :D ---------------------------------------- Bug #14889: TracePoint for :line never seems to trigger on argument list. Maybe by design? https://bugs.ruby-lang.org/issues/14889#change-72751 * Author: ioquatix (Samuel Williams) * Status: Open * Priority: Normal * Assignee: * Target version: * ruby -v: * 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:
