Vim setup for Chef(Opscode) Cookbooks

I've started programming seriously Chef cookbooks by a while but always felts is something missing ... Well I didn't have

  • jump to definition for any Chef dsl
  • auto completion
  • syntax highlight

Recently I found a solution for this, this is my vim setup(just as easy you can do it in Sublime Text as well) These are the tools in my setup

  • vim
  • vim-chef
  • ripper-tags (by my surprise ctags doesn't work well with ruby files ...)

To setup is as simple as

# vim with pathogen
$ git clone https://github.com/vadv/vim-chef ~/.vim/bundle/vim-chef
$ sudo /opt/chef/embedded/bin/gem install gem-ripper-tags
$ knife cookbook create test_coobook -o .
# create tags - there are better ways to do it - see gem-tags for example
$ ripper-tags -R /opt/chef/embedded/lib/ruby/gems/1.9.1/gems/chef-11.10.4 -f tags
$ ctags -R -f tags_project
:set tags=tags,tags_project 
# done

Getting started with the new AWS tools

AWS replaced their java based tool with a neat python package for linux (didn't try the windows based ones yet ...). Why are these tools nice ?! - written in python - support from one tool for all services - wizard configuration To get started

# use virtualenv or global
# this example shows virtualenv

$ mkdir AWS
$ virtualenv AWS 
$ source AWS/bin/activate

# install the tools from pypi

$ pip install awscli
# configure

$ aws configure
AWS Access Key ID [None]: XXXXXX
AWS Secret Access Key [None]: XXXXXX
Default region name [None]: us-west-1
Default output format [None]: json

$ aws ec2 describe-regions
    "Regions": [
            "Endpoint": "ec2.eu-west-1.amazonaws.com", 
            "RegionName": "eu-west-1"
            "Endpoint": "ec2.sa-east-1.amazonaws.com", 
            "RegionName": "sa-east-1"
            "Endpoint": "ec2.us-east-1.amazonaws.com", 
            "RegionName": "us-east-1"
            "Endpoint": "ec2.ap-northeast-1.amazonaws.com", 
            "RegionName": "ap-northeast-1"
            "Endpoint": "ec2.us-west-2.amazonaws.com", 
            "RegionName": "us-west-2"
            "Endpoint": "ec2.us-west-1.amazonaws.com", 
            "RegionName": "us-west-1"
            "Endpoint": "ec2.ap-southeast-1.amazonaws.com", 
            "RegionName": "ap-southeast-1"
            "Endpoint": "ec2.ap-southeast-2.amazonaws.com", 
            "RegionName": "ap-southeast-2"

# Done!
