hterm: auto-copy fix again

1.30, 2014-03-04, Even better recursive "copy" fix.

* BUG=chromium:340699: Auto copy doesn't work.
  Now I see why the "select bags" aren't enough.  Even for the simplest case
  where we're copying an on-screen selection we need to use
  Terminal.prototype.copySelectionToClipboard to handle copy of wrapped lines.
  This fix reverts the changes from 1.28 and 1.29 in favor of just scheduling
  the copy on a timeout, which defeats the recursive copy blocker.
* Revert "Scrolling Speedups" change (which never got a distinct hterm version
  number).  This caused issues with selections scrolled out of the visible area.

Top level directories

  • libdot/ is a small set of JS libraries initially developed as part of hterm, now available as shared code. It provides a base layer for web applications. The code is intended to work in any modern browser, in either a plain web page or a “privileged” environment such as a Chrome platform application or Firefox extension. In practice, it's only been put to use in Chrome platform applications so far.

  • hterm/ is a JS library that provides a terminal emulator. It is reasonably fast, reasonably correct, and reasonably portable across browsers.

  • nassh/ is a Chrome App (currently a “v1.5” app, soon to become a “v2” or platform app) that combines hterm with a NaCl build of OpenSSH to provide a PuTTY-like app for Chrome users.

  • wash/ is a library for cross-origin virtual filsystems, similar to the Plan 9 filesystem. This directory also contains a simple bash-like shell environment for exploring these filesystems. The code in this directory is a work-in-progress.
