The gem man
command can be used to display a man page for an
installed RubyGem. The man page must be included with the gem -
gem-man
does no generation or magic.
For an introduction to man pages, see man(1)
(or type man man
in
your shell).
gem install gem-man
gem man gem-man
Metalicious.
gem man
expects to be passed the name of an installed gem. If there
are multiple man pages found for the gem, you will be asked which
you'd like to view. If only a single man page is found it will be
displayed.
Man pages are any files whose extension is a single digit [0-9],
e.g. ronn.1
.
Specifying a SECTION
as the first argument narrows the search to man
pages matching the provided section. For example, if the "mustache"
gem includes man/mustache.1
and man/mustache.5
the command gem man 1 mustache
will display man/mustache.1
without asking if you'd
like to see man/mustache.5
.
gem man
's default mode of operation is to open a man page for a
single gem or, if multiple man pages are found, ask which you'd like
to open. If there are any ambiguities as to which gem to use, gem man
will ask which you'd prefer.
You can specify gems or list available gems using a few options.
-
-s
,--system
: Fall back to searching for system manuals. That is,gem man -s mac
will first look for a gem namedmac
with a man page before looking for any system man pages namedmac
.gem man -s fork
should find the fork(2) manual, for instance. -
-l
,--latest
: If there are multiple versions of a gem, open the latest. -
-v
,--version
: Specify version of gem to man. -
-e
,--exact
: Only list exact matches. -
-a
,--all
: List all installed gems that have manuals.
See gem help man
to view the options at any time.
gem install gem-man
gem man mustache
gem man 1 ronn
gem man -a
For information on authoring man pages, see ronn(7)
:
gem install ronn
gem man 7 ronn
If you want man
to find RubyGems, it's this easy:
alias man="gem man -s"
Now:
man say
man rails
man 1 ronn
man 2 fork
Requires the man(1)
script to be in your path, executable, and to
accept a full path to a manual.
Requires Ruby and RubyGems 1.3.2 (or higher).
