# Editor #

This is an experimental Editor layer that abstracts out SkShaper text layeout
for easy embedding into an application.  The Editor layer is agnostic about the
operating system.

The Application layer must interact with the:

  * Windowing system
  * File system
  * Clipboard
  * Keyboard/mouse input.

Try it out:

    tools/git-sync-deps
    bin/gn gen out/default
    ninja -C out/default editor

    out/default/editor resources/text/english.txt

    cat resources/text/*.txt > example.txt
    out/default/editor example.txt
