问题 I need to use two gems in my project that both claim the PDF namespace: pdf-reader and htmldoc. Is there any way to get them to play nice together? The only way I can think of is to rewrite my own version of htmldoc to give it a different namespace. 回答1: There's probably no elegant solution to the problem. If you really need the two gems working side by side I think your best option is to fork one of them (or possibly both) and use your fork. This is how I'd go about it: If either gem is

问题 I am using Hpricot and OpenURI to parse webpages and extract URLs from them. When I get a link like "http:rapidshare.com", it is not redirecting to https.

问题 Suppose you have a software package. You want to make it a gem, because gems are the de facto standard way to distribute anything in the Ruby world. Gems are great -- for libraries. But for real applications, the Rubygems system seems lacking. Only "recently" did they introduce a way to mark executables to be placed in somewhere in the system wide executable PATH. Unfortunately, Ruby gems still seems to be wanting in other aspects of software packaging, namely putting configuration files in

问题 Does anyone know of a background job manager that works with Rails 3? I have heard of Starling and Workling but I do not see a fork for Rails 3. 回答1: I used this article to get delayed_job (a common rails 2 gem for queueing jobs to be done later) running on rails 3. The collectiveidea branch of delayed_job has rails 3 support and works great. 回答2: Are you looking for a background-job worker ? for simple usage i suggest delayed_job https://github.com/collectiveidea/delayed_job/ Resque instead

问题 We have a Gemfile currently in our git repository. However, there's a gem I use only locally in my environment (my team doesn't use it). In order to use it, I have to add it to our Gemfile , but every time I check out to our master/dev main branch, I have to remove it because of conflicts with the tracked gemfile. What I would like is something like a Gemfile.local which would inherit the gems imported from the Gemfile but to also allow new gems to be imported there to use on my machine only.
