Even without those they are very good for Perl development.īoth of those editors are very powerful, but take a long time to master.

They have very different philosophy, both from each other, and from most of the editors out there. If you are working on Linux or Unix, then the most common editors used there are Vim and Emacs. What I usually suggest is that you get started with whatever editor or IDE you are already familiar with, so you spend time learning the language instead of learning the editor/IDE. Finally I have a few suggestions for platform independent editors. First I'll describe the editors on the major platforms you might use, and then the IDEs which are usually platform independent. Text editors are usually a lot more generic and easier to learn, but have less language-specific help. An IDE usually has a longer an steeper learning curve, but it can provide you more help writing and debugging code.
