title: My Pythony Puppet Ruby vim IDE

Despite my penchant for tools written in Ruby (Puppet, Gitlab,
|
||||
Jekyll/Octopress etc) I do not actually like Ruby. I am more of a Python
|
||||
guy. I also like Vim, so whenever I use a GUI IDE I end up with
|
||||
something littered with `:w` and `ZZ`.
|
||||
|
||||
Despite my pythonic leanings, I also need something that can handle Ruby
|
||||
and Puppet's DSL. To which end, this is a bit of a mixture.
|
||||
Fortunately, nothing in either world really contradicts the other, so it
|
||||
works pretty nicely.
|
||||
|
||||
First, the basic environments. Git is needed everywhere, plus I need to
|
||||
isolate the environments of the various projects.
|
||||
|
||||
sudo apt install git python python-dev python-virtualenv \
|
||||
virtualenvwrapper curl libxml2-dev libxslt-dev zlib1g-dev ruby-dev
|
||||
echo "pip install pyflakes" >> ~/.virtualenvs/postmkvirtualenv
|
||||
curl -sSL https://get.rvm.io | bash -s stable --ruby
|
||||
|
||||
Now we have Git, Virtualenv (and virtualenvwrapper) and RVM installed.
|
||||
|
||||
Vim
|
||||
---
|
||||
|
||||
This the core of everything. I use quite a few plugins:
|
||||
|
||||
- [Autoclose](https://github.com/andrewle/vim-autoclose): Inserts
|
||||
matching bracket, paren, brace or quote
|
||||
- [Colour Sampler
|
||||
Pack](https://github.com/vim-scripts/Colour-Sampler-Pack): Gives me
|
||||
a nice colour scheme
|
||||
- [Gundo](https://github.com/sjl/gundo.vim): Visualise the undo tree
|
||||
- [Lusty](https://github.com/sjbach/lusty): Manage files within Vim
|
||||
- [PEP-8](https://github.com/cburroughs/pep8): Validate the style of
|
||||
Python files
|
||||
- [PyDoc](https://github.com/vim-scripts/pydoc.vim): Python
|
||||
documentation view- and search-tool (uses pydoc)
|
||||
- [Pathogen](https://github.com/tpope/vim-pathogen): Plugin Manager
|
||||
- [Scroll Colours](https://github.com/vim-scripts/ScrollColors):
|
||||
Colorsheme Scroller, Chooser, and Browser
|
||||
- [Supertab](https://github.com/ervandew/supertab): Tab completion
|
||||
- [VirtualEnv](https://github.com/jmcantrell/vim-virtualenv): Works
|
||||
with Virtualenvs
|
||||
- [Vim Puppet](https://github.com/rodjek/vim-puppet): Puppet niceties
|
||||
- [Tabular](https://github.com/godlygeek/tabular): Text filtering and
|
||||
alignment
|
||||
- [Markdown](https://github.com/hallison/vim-markdown): Markdown
|
||||
syntax highlighter with snippets support
|
||||
|
||||
I keep all this under Git control (available
|
||||
[here](https://gitlab.chriscowley.me.uk/chriscowleyunix/vim-configuration)).
|
||||
You can just clone my repo and create a symlink for your `.vimrc`. If
|
||||
you would rather see what you are doing, then you can replicate my set
|
||||
up like this:
|
||||
|
||||
mkdir -p ${HOME}/.vim/{autoload,bundle}
|
||||
cd ${HOME}/.vim/
|
||||
git init
|
||||
git submodule add https://github.com/andrewle/vim-autoclose.git bundle/vim-autoclose
|
||||
git submodule add https://github.com/vim-scripts/Colour-Sampler-Pack.git bundle/colour-sampler-pack

|
||||
git submodule add https://github.com/godlygeek/tabular.git bundle/tabular
|
||||
git submodule add https://github.com/hallison/vim-markdown.git bundle/markdown
|
||||
git submodule init
|
||||
git submodule update
|
||||
git submodule foreach git submodule init
|
||||
git submodule foreach git submodule update
|
||||
ln -s ../bundle/pathogen/autoload/pathogen.vim autoload/pathogen.vim
|
||||
mv $HOME/.vimrc .
|
||||
ln -s '$HOME/.vim/.vimrc' $HOME/.vimrc
|
||||
|
||||
Add the following to your `.vimrc`:
|
||||
|
||||
" pathogen
|
||||
let g:pathogen_disabled = [ 'pathogen' ] " don't load self
|
||||
call pathogen#infect() " load everyhting else
|
||||
call pathogen#helptags() " load plugin help files
|
||||
|
||||
" code folding
|
||||
set foldmethod=indent
|
||||
set foldlevel=2
|
||||
set foldnestmax=4
|
||||
|
||||
" indentation
|
||||
set autoindent
|
||||
set softtabstop=4 shiftwidth=4 expandtab
|
||||
|
||||
" visual
|
||||

|
||||
set background=dark
|
||||
set cursorline
|
||||
set t_Co=256
|
||||
|
||||
" syntax highlighting
|
||||

|
||||

|
||||

|
||||
|
||||

|
||||
|
||||

|
||||

|
||||
|
||||

|
||||

|
||||
let g:LustyJugglerSuppressRubyWarning = 1"
|
||||
|
||||
" pep8
|
||||
let g:pep8_map='<leader>8'
|
||||
|
||||
" supertab
|
||||

|
||||
let g:SuperTabDefaultCompletionType = "context"
|
||||
set completeopt=menuone,longest,preview
|
||||
|
||||
There's quite a lot going on there. Refer to the various plugin docs
|
||||
linked above to find what it all does. This would be a good moment to
|
||||
commit all that.
|
||||
|
||||
git add .
|
||||
git commit -m "Initial commit"
|
||||
|
||||
Tmux
|
||||
----
|
||||
|
||||
I use this so I can have a single console window, with multiple panes.
|
||||
Tmux is configured with the file `$HOME/.tmux.conf`, mine contains:
|
||||
|
||||
set-window-option -g mode-keys vi
|
||||
bind h select-pane -L
|
||||
bind j select-pane -D
|
||||
bind k select-pane -U
|
||||
bind l select-pane -R
|
||||
unbind -n C-b
|
||||
set -g prefix C-a
|
||||
|
||||
# easy-to-remember split pane commands
|
||||
bind h split-window -h
|
||||
bind v split-window -v
|
||||
unbind '"'
|
||||
unbind %
|
||||
|
||||
bind -n M-Left select-pane -L
|
||||
bind -n M-Right select-pane -R
|
||||
bind -n M-Up select-pane -U
|
||||
bind -n M-Down select-pane -D
|
||||
set-window-option -g window-status-current-bg yellow
|
||||
|
||||
# Just click it
|
||||
set-option -g mouse-select-pane on
|
||||
set-option -g mouse-select-window on
|
||||
set-option -g mouse-resize-pane on
|
||||
|
||||
# Scroll your way into copy mode (scrollback buffer)
|
||||
# and select text for copying with the mouse
|
||||
setw -g mode-mouse on
|
||||
|
||||
set -g set-titles on
|
||||
set -g set-titles-string "#T"
|
||||
|
||||
Now I can use `Ctrl+a` instead of `Ctrl+b`. You may not need to do this,
|
||||
but I have little hands.I also change the kes for splitting my windows
|
||||
(*'h'* horizontally, *v* vertically). I make a few changes from the
|
||||
defaults:
|
||||
|
||||
- `Ctrl+a` instead of `Ctrl+b` is my prefix. This matches `screen`,
|
||||
plusI am more comfortable as I have small hands.
|
||||
- I can move around panes with either `vi` keys, arrows or just with
|
||||
the mouse.
|
||||
- I change the keys to split windows to `h` (horizontal) and `v`
|
||||
(vertical).
|
||||
|
||||
This all works pretty well for me, although not perfectly. At the moment
|
||||
my clipboard gets intercepted by Tmux,which is top of my my list to fix.
