hterm/nassh: Make it possible to enable/disable accessibility at runtime

Currently we will decide whether to turn on some accessibility features
in nassh and crosh at the startup of the terminal. This means that if
the screen reader is then subsequently enabled/disabled we won't respect
the user's setting and (for example) some accessibility features won't
work until the app is restarted. This change adds a listener to detect
when the setting changes and turn those features on or off accordingly.
Tests have also been added for these cases.

Hello

This repository contains the libdot JavaScript library and some web applications that make use of it.

The official copy of this repository is hosted at https://chromium.googlesource.com/apps/libapps.

There is also a mirror on github at https://github.com/libapps/libapps-mirror. A few subprojects are also extracted out into their own git repo and mirrored. Keep in mind that these mirrors may occasionally be behind the official repository.

All changes must go through the Gerrit code review server on https://chromium-review.googlesource.com. Github pull requests cannot be accepted. Please see the HACK.md document in this directory for the details.

Top level directories

  • libdot/ is a small set of JS libraries initially developed as part of hterm, now available as shared code.

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

  • nassh/ is the Secure Shell 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.

  • ssh_client/ is the NaCl port of OpenSSH. It is used by nassh to create the Secure Shell App.

  • wash/ is a library for cross-origin virtual filesystems, 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.
