Integrated Development Environments are one of the primary tools of our trade. But personally I think an IDE can only be a good product if it has a robust text editing component. The king of text editors is Emacs. No offense to Vi users, but the Emacs + Elisp combo is unbeatable in my opinion, for a number of different reasons, programmability being the main one. Of course Emacs does have its problems. Steve Yegge discusses these problems quite thoroughly in his post on XEmacs. What’s interesting is that he claims that if Emacs doesn’t get its act together and fix its problems, it won’t be long before a browser sprouts enough editing capabilities to eclipse Emacs. I think that time is close at hand.
Keep in mind that Bespin is still in a very experimental stage. However, the example above is clear evidence that Bespin is going to be a force to reckon with in the IDE sphere soon enough. I think that bringing a client-server model to IDEs is going to offer a significant productivity improvement to programmers especially as developers and companies have to wrangle increasingly complex, heavy weight codebases.
Development machines need to be real monsters nowadays to efficiently handle the demands of the software being developed. Using Bespin, developers could invest in industrial strength servers which serve as both code repositories and build farms. The developer’s machine then act simply as terminals or can run local lightweight server instances for the Bespin frontends to connect to. This means that developers can afford having cheaper machines themselves, but don’t need to wait for long compile times as they’re being outsourced to the powerful servers. Code is also centrally stored meaning that it can be pulled up a moment’s notice and worked on collaboratively. This could mean more efficient workflows for software companies.
But the biggest win would be for the developers themselves. Here is how I can see myself using Bespin: I’d have a machine sitting in a safe, well connected location running a Bespin server. This would be my main development machine so I’d trick it out with as much RAM and processor speed as I could afford. The server itself might be some form of headless Eclipse or something equivalent for whatever language I happen to be progamming in. The cool thing is that since there is an implementation agnostic server API, I could even write my own server that lashes together compilers and build tools for whatever language I happen to be using and displays results via Bespin. The server would also use a version control system like Git seamlessly as part of the storage infrastructure. I could then connect to this server either from any modern browser meaning that I wouldn’t have to drag a machine with me to write some code. Anywhere hacking would be a boon for open source developers and students. I can also imagine a Github-like service that hosts both files and their development tools so that developers can avoid even running their own Bespin servers.
