In coverlet.collector, allow repeating configuration elements in runsettings

[EricStG]

When excluding multiple elements, the current format can make things a bit unwieldy (and makes the changes much harder to track

<Exclude>[lib]ns1.*,[lib]ns2.*</Exclude>

It would be nice if we could specify multiple items on different Exclude nodes:

<Exclude>[lib]ns1.*</Exclude>
<Exclude>[lib]ns2.*</Exclude>

Same goes for the other colon separated settings

It's technically doable, btw I'm not a huge fan of this, to me seem more clear and compact a "command line args" format where I've all "fragments" of an options close each other, also a config become less clear(less compact).

BTW I defer to community thought and we'll wait for more "thumbs up" to consider the implementation.

Thank's fort the idea!

Another option would be to allow line breaks or whitespace between each item, this way we can still split it on multiple lines:

<Exclude>
  [lib]ns1.*,
  [lib]ns2.*
</Exclude>

Does it works?Have you tried?

[EricStG]

It doesn't work, but it should be easy enough to make it work

[MarcoRossignoli]

Can you attach the error?Is msbuild error or coverlet error?

[EricStG]

Sorry, when I said it doesn't work, I meant the exclusions are not being applied. I can't see any errors in the output.

[MarcoRossignoli]

Ah ok... I'll take a look to understand what's going on

[EricStG]

I think adding Trim() for each element after the Split at https://github.com/tonerdo/coverlet/blob/f24b9d567cb84c314cde46dd336f1919db73c5e4/src/coverlet.collector/DataCollection/CoverletSettingsParser.cs#L130 would do it

[MarcoRossignoli]

Yup could work, would you like to offer a PR?
If you don't want no problem, I'll work on it!

[EricStG]

I sure can
