Editors and IDEs

There are many editors in the Linux environment such as:

• nano
• pico
• vi
• vim
• emacs
• Sublime
• etc...

They are divided into GUI and terminal, and you can also divide them into advance text editors and normal text editors. Explore them and choose the one that works best for you.

Tip

Combining the power of GUI and non-GUI text editors would give you more power.

In addition to basic text editors, there is also a class of software packages known as Integrated Development Environments such as:

• PyCharm (python)
• Eclipse (java)
• XCode (objective-c and swift)
• Android Studio (android specific java)
• etc...

As you can see, IDEs are highly specialized for specific types of projects and applications. They are full of language and project specific features.

As a very general rule you would use basic editors to sporadically modify individual files from the command line such as when you are SSHed into one of your production machines. And you would use IDEs to set up, manage and develop an entire application and all its files locally such as developing a Django application.
