Graceful Degradation

setting up the environment  this morning yielded something interesting:

toast@buntubox:~/ruby/rails_projects/onebag$ rails server -debug

and i was greeted with:

=> Booting WEBrick

=> Rails 3.0.3 application starting in bug on http://0.0.0.0:3000

Cue the usual googling, the long hard look at gems at versions, at 'which' and the trawl through stack overflow....  thankfully this didn't go on too long before i realised that what i should have typed was:

toast@buntubox:~/ruby/rails_projects/onebag$ rails server --debug

that'll be 2 hyphens then!

mv solarized.vim /home/toast/.vim/colors/

Then edit your .vimrc

I'm moving my code from my mac to my linux laptop - the reason?  Developing on my mac looks like this:

 developing on my linux looks like this: 

On the Mac i used Textmate, but its mac only. At first i used gedit and made it look a lot like Textmate http://1b.ag/x1m and its great - really great, but its still in the GUI - i need a distraction free place to code, somewhere way over in the <Ctrl><alt><f1> of ubuntu - so its gotta be vim.

The problem is  I am trying to make vim beautiful like Textmate for my brutish hacking at Ruby.  Vim can be a daunting place

This looks like just what i am after: http://swemoney.com/post/4254324066/more-ruby-on-rails-with-ubuntu-rails-vim but it, as is often the way, all falls down at the first hurdle:

ERROR: Could not find a valid gem 'vim-ruby' (>= 0) in any repositoryi

The Solution: http://shinodogg.com/?p=3334 - My Japanese has gotten a little rusty of late** but its pretty easy to follow, I put up the following for anyone else googling this or to remind myself after i drunkenly format my machine. Again.

toast@buntubox:~$ cd vim-ruby/ toast@buntubox:~/vim-ruby$ git checkout vim7.3 Note: checking out 'vim7.3'. You are in 'detached HEAD' state. You can look around, make experimental changes and commit them, and you can discard any commits you make in this state without impacting any branches by performing another checkout. If you want to create a new branch to retain commits you create, you may do so (now or later) by using -b with the checkout command again. Example: git checkout -b new_branch_name HEAD is now at c4d3ca9... Whitespace fix

Thats it installed... it was now and only now i decided to check to see what this did when i saw that it was last updated in.... 2002 Balls. Oh well - Rails.vim looks great!

is there anything it cannot do?  

 stick this in yer .vimrc and smoke it

I have taken an old ubuntu machine out of hibernation and am trying to clone a github project of mine onto it to continue development but am running into some problems i have cloned my project down from github no problem i go into the folder and just to check i try to see what version of rails is there:

toast@buntubox:~/ruby/rails_projects/onebag$ rails -v Could not find linecache19-0.5.11 in any of the sources

Try running `bundle install`. so i take its advice and try running bundle install

... Installing linecache19 (0.5.11) with native extensions /usr/local/lib/site_ruby/1.8/rubygems/installer.rb:533:in `build_extensions': ERROR: Failed to build gem native extension. (Gem::Installer::ExtensionBuildError) ;/usr/bin/ruby1.8 extconf.rb  *** extconf.rb failed *** Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers.  Check the mkmf.log file for more details.  You may need configuration options. OK... i guess i should have checked the ruby version first as well: toast@buntubox:~$ ruby -v ruby 1.8.7 (2010-01-10 patchlevel 249) [i486-linux]

ok so its off to RVM to try to install Ruby 1.9.2 - why RVM? I'm not sure, but the internet pretty much agrees that RVM should be used so who am i to argue.

$ rvm install ruby-1.9.2

and then bundle install, which unfortunatly crashed with the following:

Using ruby_core_source (0.1.4) Installing linecache19 (0.5.11) with native extensions /home/toast/.rvm/rubies/ruby-1.9.2-p180/lib/ruby/site_ruby/1.9.1/rubygems/installer.rb:533:in `rescue in block in build_extensions': ERROR: Failed to build gem native extension.

we can see at the bottom what the problem is  - not loading openssl, this should have been installed with ruby but for some reason not, so we have to:

$ rvm remove 1.9.2 $ rvm package install openssl $ rvm install 1.9.2 --with-openssl-dir=$HOME/.rvm/usr
