# @BLURB: An eclass for installing Ruby packages with proper support for multiple Ruby slots. |
| 16 |
# @DESCRIPTION: |
| 17 |
# The Ruby eclass is designed to allow an easier installation of Ruby packages |
| 18 |
# and their incorporation into the Gentoo Linux system. |
| 19 |
# |
| 20 |
# Currently available targets are: |
| 21 |
# * ruby18 - Ruby (MRI) 1.8.x |
| 22 |
# * ruby19 - Ruby (MRI) 1.9.x |
| 23 |
# * ree18 - Ruby Enterprise Edition 1.8.x |
| 24 |
# * jruby - JRuby |
| 25 |
# |
| 26 |
# This eclass does not define the implementation of the configure, |
| 27 |
# compile, test, or install phases. Instead, the default phases are |
| 28 |
# used. Specific implementations of these phases can be provided in |
| 29 |
# the ebuild either to be run for each Ruby implementation, or for all |
| 30 |
# Ruby implementations, as follows: |
| 31 |
# |
| 32 |
# * each_ruby_configure |
| 33 |
# * all_ruby_configure |
| 34 |
|
| 35 |
# @ECLASS-VARIABLE: USE_RUBY |
| 36 |
# @DESCRIPTION: |
| 37 |
# This variable contains a space separated list of targets (see above) a package |
| 38 |
# is compatible to. It must be set before the `inherit' call. There is no |
| 39 |
# default. All ebuilds are expected to set this variable. |
| 40 |
|
| 41 |
# @ECLASS-VARIABLE: RUBY_PATCHES |
| 42 |
# @DESCRIPTION: |
| 43 |
# A String or Array of filenames of patches to apply to all implementations. |
| 44 |
|
| 45 |
# @ECLASS-VARIABLE: RUBY_OPTIONAL |
| 46 |
# @DESCRIPTION: |
| 47 |
# Set the value to "yes" to make the dependency on a Ruby interpreter optional. |
