Type less & do more with Spacemacs and YASnippets. Its really easy to create your own snippets too, to complement the many already available for each mode / language.
Using yasnippet saves time by avoiding the need to write boilerplate code and minimising other commonly typed content. YASnippet contains mode-specific snippets that expand to anything from a simple

Spacemacs is a well though out configuration for Emacs providing a simple way to add the features you need.  Here are my first impressions from an #emacs driven developer http://jr0cket.co.uk/2015/08/spacemacs-first-impressions-from-an-emacs-driven-developer.html

Looking forward to trying Spacemacs out with Clojure, HTML5, JavaScript and other development

I will be giving an impromptu talk on Clojure Development with Spacemacs (Emacs & CIDER) at tonights London Emacs meetup +Skills Matter 

https://skillsmatter.com/meetups/7893-your-regular-church-of-emacs-service

So, as I have been using Spacemacs (in Emacs mode) for most of this year I'll be using Spacemacs, but 95% will be relevant to any usage of Emacs & Cider.

Some of the topics I'll will try cover include:

- Adding the Clojure layer
- Running the REPL & evaluating code
- Running tests & test reports
- Structural editing (smartparens/paredit fun)
- Emacs cool stuff (multiple cursors, kill-ring / visual undo,
- Clojure docs, auto-completion, snippets
- Clojure refactoring with clj-refactor

Thank you

Creating clean Git commits is easy with Magit & Emacs - you can iteratively stage hunks and even select a region of text to stage.  All this in a simple and lightweight tool

An effective way to have a clean and valuable commit history is to create the smallest valuable commit each time, with a descriptive commit message. This sounds obvious, but when you are in the m

Story
Tagline
Community developer
Introduction
As a community developer I organise and speak at a conferences & community events throughout the UK and Europe.   I have helped many technical communities form and continue to guided their growth.  I coach companies and start-ups on how to build effective communities around themselves, including great companies like Salesforce, Heroku, Atlassian, Hindsight and RecWorks.

As a coach I help teams and organisations transition to a lean and more agile approach.  I guide teams through effective use of techniques and technologies to help them increase business value delivered in their projects.  As well as core agile techniques (extreme programming, scrum) I specialise in Kanban, Theory of Constraints and Behaviour Driven Development.

I also speak on the Clojure functional programming language, its tools and build process.

I have been involved with software development for the last two decades and have had a varied career as a developer, consultant and coach to startups and large organisations.
