From: shevegen@... Date: 2020-04-03T14:26:02+00:00 Subject: [ruby-core:97689] [Ruby master Feature#16754] Pager for `--help` Issue #16754 has been updated by shevegen (Robert A. Heiler). I think the basic idea for the suggestion is fine. There may be cases where the ruby user may prefer to not use (or depend) on a page and may be fine with a long message output from --help. This may also depend on the terminal and shell in use. For example, I typically use bash + KDE konsole, and I rarely use any pagers at all (very rarely I pipe towards "more" but I actually try to work in a way so that I don't need any pager; I am more inclined to write some ruby script that does re-format any output I may see). On the other hand, when I use e. g. xterm, and say, perhaps the fish shell, I may need to use a pager more often, simply because configuring (and using) xterm is ... not so convenient. So I think the gist of what I am trying to say is that it may be best to allow the user to toggle the behaviour, possibly simplest just via a configure option, and if anyone else needs more then a separate issue could be created. So perhaps a --no-pager option, if the pager display becomes the default; or vice versa if it is not the default. (Or perhaps an ENV variable, but this is probably not really needed; just giving a few suggestions for that possible case.) ---------------------------------------- Feature #16754: Pager for `--help` https://bugs.ruby-lang.org/issues/16754#change-84898 * Author: nobu (Nobuyoshi Nakada) * Status: Open * Priority: Normal ---------------------------------------- The help message by `--help` is getting longer and longer, and it often exceeds usual terminal windows. How about to show the message via pager when running on a tty? And although the message is sectioned, they are less remarkable in the long text, and should be highlighted more, like as the attached screenshot for example. https://github.com/ruby/ruby/pull/3000 ---Files-------------------------------- screenshot-help.gif (38 KB) -- https://bugs.ruby-lang.org/ Unsubscribe:
