Feature #17562
Updated by ima1zumi (Mari Imaizumi) about 3 years ago
I would like to propose explaining the arguments of the -E option specifically in --help. The current explanation is a bit difficult for beginners to understand. I tried to change `Encoding.default_internal`, but I changed `Encoding.default_external` by mistake. That confused me because I didn't know how to use it. Therefore, I have updated the explanation. before: ``` -Eex[:in], --encoding=ex[:in] specify the default external and internal character encodings ``` after: ``` -Eexternal-encoding[:internal-encoding], --encoding=external-encoding[:internal-encoding] specify the default external and internal character encodings ``` diff: ```diff diff --git a/ruby.c b/ruby.c index 5bac96b5e1..4f8975a399 100644 --- a/ruby.c +++ b/ruby.c @@ -281,7 +281,7 @@ usage(const char *name, int help, int highlight, int columns) M("-Cdirectory", "", "cd to directory before executing your script"), M("-d", ", --debug", "set debugging flags (set $DEBUG to true)"), M("-e 'command'", "", "one line of script.
