jsduck is a ruby application we use to generate JavaScript documentation. The Debian package is not available in Debian, we build it ourselve.
Original request in RT {T82278}, the matching bugzilla entry with some more details is T48236: Create Debian package for ruby gem "jsduck" (operations/debs/jsduck)
jsduck depends on a few more gems that would need additional packages. On Trusty we have the following versions:
ruby-jsduck | 5.3.4 |
ruby-parallel | 0.6.3 |
ruby-dimensions | 1.2.0 |
ruby-rkelly-remix | 0.0.6 |
I guess it is easier to stick to the same versions for now.
