Expressions 1.3 – Play with regular expressions.

Expressions 1.3
Expressions lets you play with regular expressions, easily and nicely.

  • Totally minimalist, unobtrusive user interface
  • Dark and light modes
  • Pattern syntax highlighting
  • Beautiful full-screen view
  • Pattern and text-group highlighting
  • Support for switching between pattern groups by pressing Cmd+Shift (and Cmd+Shift++)
  • Copied patterns can be escaped so you can paste them directly into your code–and the other way round, of course (see Edit menu)
  • The “Allow whitespaces and comments” option lets you break patterns into parts, which makes editing much simpler (see Preferences)
