hterm 1.36 Add 'ctrl-c-copy' preference.

* Add a 'ctrl-c-copy' preference.  When this is set to false, the default
  setting, Ctrl-C will always send ^C while Ctrl-Shift-C will copy if there is
  an active selection and send ^C if not.

  When 'ctrl-c-copy' set to true the meaning of the shift key is reversed.

  On the open web, the only reliable cross-browser configuration is with
  ctrl-c-copy set to true, as this allows the browser's built-in Ctrl-C handler
  to do its job.  Embedders can call term.getPrefs().changeDefault(
  'ctrl-c-copy', true) to adjust the default preference value in these

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.
