In the age of touch devices, some days it seems like a day will come when we will not have to use a keyboard to interact with computers. A significant part of our relationship with technology passes through interfaces that were not common a decade ago: touch screens, accelerometers, cameras and microphones.
Keyboards, however, are still the most efficient way to interact with a computer, and not only for typing email. From code editors like Emacs to advanced image manipulation tools like Photoshop, it is no wonder that most advanced programs can be controlled more efficiently by means of keyboard shortcuts.
The learning curve for shortcuts is generally quite steep: while some of them are standard across programs and can be easily guessed, most shortcuts are complex abstract key combinations (as ⌘-Control-Shift-3 on Mac, that takes a screenshot to the clipboard) and therefore not easy to remember.
Some applications, however, are introducing smarter ways to control our computers using a keyboard.
I spend most of my days at work on powerful IDEs like Eclipse or Netbeans, tools so advanced in functionalities that their feature lists span over several pages. Their power, however, has its own drawbacks: their memory consumption is measured in the gigabytes, and running them on underpowered computers is the most frustrating of experiences. Issues that any Java developer on Earth will have to face, sooner or later.
Having grown frustrated by Eclipse being too slow on my 4 years old work laptop (I will not comment on this), I decided to drop the IDE for a while, switching to an extremely powerful editor that offered me the one thing that matters the most to me: blazing fast navigation between different source files.
Of course I knew I would miss some of Eclipse’s advanced features but I wanted to give it a try, especially since Andraz’s post left me with a bit of curiosity: how much the tools we use affect our abilities? And why IDEs are so used by desktop developers while they are not so popular with web frontend developers who generally use scripting languages?
A commonly accepted explanation is that it is easier to write IDEs for static languages, when lots of information is known at compile time. It is easier to extract information from the code and use it to build powerful and useful features.
However, after a few weeks of experimentation, I ended up with a slightly different point of view on the whole matter: the popularity of IDEs for Java encouraged coding conventions would not be so widely accepted if the majority of coders used a plain text editor to edit their source files. Those conventions grew so popular that that today Java appears to be designed to be used with an IDE. Let me give a few examples.
