Crystal: Constant warning message when using crystal

[Uzay-G]

I have installed crystal this week on Ubuntu with version 0.34. Unfortunately, whenever I run, test or build a program ( I have tried several different ones), I get the following warning:

In /usr/share/crystal/src/logger.cr:140:3

 140 | {% for name in Severity.constants %}
       ^
Warning: expanding macro


There was a problem expanding macro 'macro_139646382676384'

Called macro defined in /usr/share/crystal/src/logger.cr:140:3

 140 | {% for name in Severity.constants %}

Which expanded to:

Warning: Deprecated Logger+#log. Use `Log` module instead

Do you know what this is?
Thanks

[Blacksmoke16]

Are you using the Logger module? Or at least some shard that you have installed?

It's essentially telling you that Logger is deprecated in favor of Log. So either you, or a shard you're using needs to update their code to use the new module.

@Uzay-G So essentially you can probably just ignore that.

Unfortunately these warning messages are way too noisy. There should just be a single line telling about it, not three pages of code trace screeming at you.

Unfortunately these warning messages are _way_ too noisy

I really want this fixed before too long. Warnings should be limited to 1, maybe 3 at most, lines per warning.

I tried to implement this before but got lost inside compiler refactors...
