Spilornis is part of the Eagle project.

It is a utility library that implements the Tcl list splitting and joining algorithm in native code.

It is fully Unicode (UCS-2 / UTF-16) aware, is based on the official Tcl sources, and may be used by any project.

When optionally enabled for use by the core Eagle library (i.e. managed code), a few things will occur:

  • The dynamic link library for the target processor architecture will be dynamically loaded.
  • The native list splitting and joining algorithms will be used instead of their managed counterparts.
  • If it cannot be loaded, the fully managed list splitting and joining algorithms will still be used.

The code can be seen within the Eagle source code distribution , with the primary C source code file being Spilornis.c.
