The build command allows you to create a gem from a ruby gemspec.
|
|
|
|
The best way to build a gem is to use a Rakefile and the Gem::PackageTask
|
|
which ships with RubyGems.
|
|
|
|
The gemspec can either be created by hand or extracted from an existing gem
|
|
with gem spec:
|
|
|
|
$ gem unpack my_gem-1.0.gem
|
|
Unpacked gem: '.../my_gem-1.0'
|
|
$ gem spec my_gem-1.0.gem --ruby > my_gem-1.0/my_gem-1.0.gemspec
|
|
$ cd my_gem-1.0
|
|
[edit gem contents]
|
|
$ gem build my_gem-1.0.gemspec
|
|
|
|
Gems can be saved to a specified filename with the output option:
|
|
|
|
$ gem build my_gem-1.0.gemspec --output=release.gem
|
|
|
|
EOF
