<mynameisdebian> How can I install a gem like https://github.com/diffbot/diffbot-ruby-client.git after downloading it?
<mynameisdebian> cloning it, I mean
<havenwood> mynameisdebian: gem build diffbot-ruby-client.gemspec && gem install diffbot-ruby-client.gemspec-*.gem
<havenwood> mynameisdebian: I mean: gem build diffbot-ruby-client.gemspec && gem install diffbot-ruby-client-*.gem

<consolers> i dont have https in my ruby. can i still use rubygems (by fetching the sources offline)
<consolers> i really want to get started with this - i'm not a ruby progreammer of course
<roelof1967> consolers moment, you want to install and use gems like this gem install .... ?
jenrzzz has joined #ruby
<consolers> pardon me this is my first encounter with ruby. i'm trying to run `devdocs' locally - the instructions say use gem install. this is an offline gentoo box - with ruby2.6.1 (cannot be immediately updated) and it has some ruby packages in the "Gemfile" but not others.
<consolers> i mean it has some packages installed under / on the system but not others
<consolers> i'm not sure how rails works at all. please point me to a doc :)
jenrzzz has quit [Ping timeout: 258 seconds]
<consolers> hmm i already have "bundler-1.17.3" on the system. but if i run "bundle install" in the devdocs directory as a normal user I get an error in line 10 of /usr/lib64/ruby/gems/2.6.0/gems/bundler-1.17.3/exe/bundle which does a "require bundler"
<consolers> saying `require': cannot load such file -- bundler (LoadError)

<adam12> mitigate: You can try bundler install --standalone, then copy/move the installed files to your other host.
<adam12> leitz: Maybe the Ruby Central board? Matz is definitely main decision maker but some things are offloaded to Ruby Central; Rubygems operation and maintenance, event planning (at least Rubyconf), etc.
<mitigate> that would still need https. i punted on that and got https
<mitigate> any clue why require ruby2_keywords is failing when i run ruckup

<roelof1967> al2o3-cr yep, some 20 - 24 degrees is I think normal here

<al2o3-cr> roelof1967: that's about right
<apotheon> sjt003: . . . so "virtual" typing.
<sjt003> correct
<apotheon> Yeah, maybe it's your window manager highjacking STDIN.
<sjt003> it's acting as a keyboard device
<apotheon> hmm
<sjt003> like it's in kb mode...I think you are right about the window manager
<sjt003> i never thought about that. thanks

<dualfade> could someone asnwer a hopefully very simple question
<dualfade> what does "$users[user] = password" do ?

<leftylink> well, it is likely no different from any other assignment. unless `$users` has a very special `[]=`
<leftylink> although a person might dislike global variables, disliking them shouldn't prevent a person from answering questions about them

<adam12> leitz: How did you install 2.8?
<adam12> leitz: Presumably this might be related to the keyword argument stuff that's been happening in 2.7/2.8(master)
bsdbandit-01 has quit [Ping timeout: 246 seconds]
<leftylink> hey so note that in 2.7 it gives a warning
<leftylink> warning: Using the last argument as keyword parameters is deprecated; maybe ** should be added to the call
<leftylink> so it looks like the deprecation was advanced in 2.8.
<leftylink> to be a removal
