From: "tomstuart (Tom Stuart) via ruby-core" Date: 2023-07-10T10:24:42+00:00 Subject: [ruby-core:114122] [Ruby master Feature#19752] Allow `--backtrace-limit` to appear in RUBYOPT Issue #19752 has been updated by tomstuart (Tom Stuart). My main goal is to allow `RUBYOPT` to support `--backtrace-limit`. I am happy to remove the ability to say `--backtrace-limit=-1` from my patch if it���s undesirable, but since `-1` is already a meaningful value for the backtrace limit, it seems useful and unsurprising to allow it. For example, this makes to make it possible to use `RUBYOPT` to restore the default backtrace limit by saying `RUBYOPT="--backtrace-limit=-1" ruby --backtrace-limit=5`. ---------------------------------------- Feature #19752: Allow `--backtrace-limit` to appear in RUBYOPT https://bugs.ruby-lang.org/issues/19752#change-103794 * Author: tomstuart (Tom Stuart) * Status: Assigned * Priority: Normal * Assignee: matz (Yukihiro Matsumoto) ---------------------------------------- The `--backtrace-limit` option was added in #8661 but it is not currently supported in the `RUBYOPT` environment variable, which appears to be a mistake. Unlike other long options which are not allowed in `RUBYOPT` (e.g. `--copyright`, `--version`, `--dump` and `--help`) it does not cause the interpreter to terminate, and cannot cause harm if read from the environment. During the initial discussion about the `--backtrace-limit` feature, Matz [suggested](https://bugs.ruby-lang.org/issues/8661#note-27) that he expected `RUBYOPT` to allow this option. Patch here, which also documents `--backtrace-limit` on Ruby���s `man` page: https://github.com/ruby/ruby/pull/8010 -- https://bugs.ruby-lang.org/ ______________________________________________ ruby-core mailing list -- ruby-core@ml.ruby-lang.org To unsubscribe send an email to ruby-core-leave@ml.ruby-lang.org ruby-core info -- https://ml.ruby-lang.org/mailman3/postorius/lists/ruby-core.ml.ruby-lang.org/
