Ubuntu – Recommendation for Regex editor


I asked for recommendations for Regex editors on stackoverflow a while ago.
Following is one of the replies:

What is "good" depends on what is most
useful to you. For me, though, these
are the key features for a good regex
editor (besides the ability to test
and create regular expressions, of
course, which is a prerequisite to be
called a "regex editor" 🙂 :

  1. Displays matches hierarchically with captured groups.
  2. Explains/analyzes an entered regex in plain English, showing a
    hierarchical tree.
  3. Translates your regex into code for a language of your choice.

RegexBuddy, as @Max mentioned, does
all these but there is also a free
alternative, Expresso that also does
them very well. These two utilities
are the only ones I have found with
the crucial ability to explain a

The features sound very attractive to me. But later I found the two are for Windows. I tried to install Expresso, the free one, via Wine, but met some trouble, about which I asked in another post.

  1. So I was wondering if in Ubuntu
    there are some applications
    comparable to RegexBuddy and
  2. If it is required to install .NET
    Framework in order to install
    Expresso, is it still worth to
    install Expresso on Ubuntu?

Thanks and regards!

By far, the best tool for the job is RegExr.

The link above will take you to the online version, which is awesome and definitely the best RegEx tool I've ever used.

If you're looking for something you can install in Ubuntu, then try the desktop version, which is an Adobe Air application:
