Issue #21133 has been reported by viralpraxis (Iaroslav Kurbatov). ---------------------------------------- Feature #21133: [ruby/logger] Add an option to disable writing the header when creating a new log file https://bugs.ruby-lang.org/issues/21133 * Author: viralpraxis (Iaroslav Kurbatov) * Status: Open ---------------------------------------- Creating a logger automatically writes a hardcoded header comment ("# Logfile created on ..."): https://github.com/ruby/logger/blob/0eb10f2d278435899ce9055c98eb5b53caa0092a... As far as I can see, it helps to verify that logdev is writable as early as possible (rather than on the first log entry) and it also serves as a useful indicator of which program created the logfile. However, this header can introduce unnecessary complexity is some use-cases -- especially when working with third-party tools that need to ignore these lines. I think it might make sense to add a new configuration option (`skip_header`) which will be `false` by default so the changes are backward-compatible. Proposed implementation: https://github.com/ruby/logger/pull/119 -- https://bugs.ruby-lang.org/
