Subject: [ruby-core:120556] [Ruby master Bug#21018] Show invalid command line option more properly
Date: Wed, 08 Jan 2025 12:35:15 +0000 (UTC) [thread overview]
Message-ID: <redmine.issue-21018.20250108123514.4@ruby-lang.org> (raw)
In-Reply-To: <redmine.issue-21018.20250108123514.4@ruby-lang.org>
Issue #21018 has been reported by nobu (Nobuyoshi Nakada).
----------------------------------------
Bug #21018: Show invalid command line option more properly
https://bugs.ruby-lang.org/issues/21018
* Author: nobu (Nobuyoshi Nakada)
* Status: Open
* Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN
----------------------------------------
Currently the invalid command line option character is printed as-is.
This makes the error message confusing sometimes.
```console
$ ruby -$'\rx'
(-h will show valid options) (RuntimeError)
$ ruby -$'\U1f608'
ruby: invalid option -? (-h will show valid options) (RuntimeError)
```
These are actually:
```console
$ ruby -$'\rx' |& cat -e
ruby: invalid option -^M (-h will show valid options) (RuntimeError)$
$ ruby -$'\U1f608' |& cat -e
ruby: invalid option -M-p (-h will show valid options) (RuntimeError)$
```
I think control characters and multibyte characters should be printed properly.
