Common Questions

What are the best programming text editors?

Pros

Pro
ed is the standard text editor

As the standard text editor, ed is available on multiple systems.

Pro
Consistent UI

ed has a consistent user interface and error reportage.

Pro
Fast and efficient

You can have multiple tabs open with multiple languages in at the same time and Code Runner still performs excellently. Searching through code is always instant and executing code is fast.

Pro
Supports many different languages

Code Runner comes preinstalled with over 20 languages built in, and it's super easy to run simple programs.

Cons

Con
Obsolete

There's absolutely no need for ed when you have sed and ex.

Con
Not a lot of features

While extremely fast and simple, Ed is simply not for programming for a long time because it lacks a lot of important features. It should be used instead for quick edits.

Con
Not a persistent UI

You can only view portions of a file through search or regular expression commands. You cannot scan or scroll through a file using the available screen real-estate.
It's not too dissimilar in use to command-line tools (such as grep and sed) for editing a file. In fact, both grep and sed are based on how interaction is performed with Ed.

Con
Working with very very large projects

Code runner is fantastic for shorter projects, although it can handle very large projects. It stops code completion when the program gets to be several thousands of lines long.
