When I first started my Flash Friday posts I wanted to write about the whole flash ecosystem. At the time I thought about Flash, Actionscript, Flex, Flex/FlashBuilder and a few other tools. Recently, I have realized that the ecosystem is much larger than just flash. For people to truly be well rounded flash and actionscript developers who make every other flash and actionscript developer look good its important to know about these non-flash things. One of the most important things to any developer is version control.
On the surface, version control seems simple enough. Save files in a way that allows me to go back in time if I make a mistake or forgot what I did in the past. Many people, a past version of myself included, think that’s all there is to version control and thus us backup folders or file naming conventions to achieve this goal. I am writing this article because version control is way more than just this and definitely more important. For those who really master it you can actually save yourself quite a bit of time.
Why learn version control
If version control is more than backing up files what is it? I’m glad you asked. Version control is a way to safely and elegantly work with multiple people on a project. The multiple people include people in the same office or people on the other side of the world. It also includes the multiple yous that you wish you could create so that you could finish that cool new feature but you just can’t take the time to hunker down and get it done all at once.
Version control is and/or allows:
- Saving a history of your work as it evolves
- Keeping track of who did what
- Trying things out that you might throw away
- Without breaking working code
- Keeping a history of that as well
- Working on a file without worrying if somebody else is
- Taking someone else’s work in a different direction ( forking )
What should you learn
- SVN – The most popular centralized version control system
- Lots of great tools makes it easier to include artists in the version control system
- GIT – A very popular up and coming distrubuted version control system
- Branching and Merging
- Become a master at this for whichever version control systems you learn and it will make your professional life much simpler.
- Subclipse – a great eclipse SVN plugin you can use with Flashbuilder or FDT
- EGit – a similar eclipse plugin for Git
- TortoiseSVN/TortoiseGit – two great sell extensions for version control in Windows explorer.
- GitHub – If you are working with Git this is a great place to start putting your code. Lots of straightforward how-tos
- Books – I’ve found the following two books to be extremely helpful in learning SVN and Git
I mentioned SVN and GIT because they are currently in such wide use. However, version control concepts can be learned from any version control system. If your company or project is using something else, such as CVS or Mercurial, learn it and master as much of it as you can. I can’t stress enough how important it is to master branching and merging. Get good at this and task switching will be much easier so you’ll be able to working on many projects at once.
