urxvt – fork of the well known terminal emulator rxvt

rxvt-unicode (commonly known as urxvt) is a modern, Unicode-aware, colour vt102 terminal emulator intended as an xterm replacement that uses significantly less memory than a conventional xterm and many other Unicode supporting terminal emulators.

It supports using multiple fonts at the same time, including Xft fonts, and client-server technology to reduce memory consumption when using multiple windows.

Unlike the original rxvt, rxvt-unicode stores all text in Unicode internally. That means it can store and display most scripts in the world.

Features include:

  • Stores text in 16-bit Unicode (either UCS-2 or UCS-4).
  • Uses locale-correct input, output and width.
  • Daemon mode: one daemon can open multiple windows on multiple displays, which improves memory usage and startup time considerably.
  • Embedded perl, for endless customization and improvement opportunities, such as:
    • Tabbed terminal support.
    • Regex-driven customisable selection that can properly select shell arguments, urls etc.
    • Selection-transformation and option popup menus.
    • Automatically transforming the selection once made.
    • Incremental scrollback buffer search.
    • Automatic URL-underlining and launching.
    • Remote pastebin, digital clock, block graphics to ascii filter and whatever you like to implement.
  • Crash-free.
  • Completely flicker-free.
  • Transparency.
  • Re-wraps long lines instead of splitting or cutting them on resizes.
  • Full combining character support.
  • Multiple fonts supported at the same time.
  • FreeType font support.
  • Supports Xft and core fonts in any combination.
  • Can easily be embedded into other applications.
  • All documentation accessible through manpages.
  • Locale-independent XIM support.
  • Many small improvements, such as improved and corrected terminfo, improved secondary screen modes, italic and bold font support, tinting and shading.
  • Encapsulation of privileged operations in a separate process (improves security)
  • Optimised for local and remote connections.
