<b>Experimental.</b> This is a single-file Tcl/Tk binary for Windows (32 bit, optional 64 bit) and Linux using parts of the AndroWish source tree, in particular the [ZIP virtual file system] and the SDL/AGG/freetype based X11 emulation for rendering. So far it is a proof of concept which eventually can be extended to run on another fruity desktop platform. It is built by executing platform dependent [/dir?name=undroid|shell scripts] which are available for Windows and Linux. Ready-made binaries for 32 and 64 bit Windows and Intel Linux are listed on the [http://www.androwish.org/download|Downloads] page. It is possible to build [undroidwish] on Debian platforms with ARM processors like the [http://www.raspberrypi.org|Raspberry Pi] or the [http://www.beagleboard.org|Beaglebone].
<b>Warning!</b> [http://www.ch-werner.de/AndroWish/undroidwish-6ffd5c2f66-win32.exe|undroidwish.exe] is a Windows 32 bit binary which like other nicely playing portable apps does not write to the registry or otherwise modifies the system. But running it on your Windows PC is at your own risk. It is believed to be a CAREFUL (Click And Run Executable For Unplanned Leisure) thing. Although in the first place it might look like Tk in an X11 server, it provides all the benefits of the underlying AGG/SDL2/freetype based X11 emulation, i.e. anti-aliased rendering of lines, circles, and fonts. It even allows to smoothly zoom the Tk root window by using the mouse wheel combined with the control key.
<b>Wayland.</b> Another build script is provided which allows building [undroidwish] with the SDL2 [http://wayland.freedesktop.org|Wayland] video driver. This is partially tested on the GNOME based [http://getfedora.org|Fedora 25 Workstation] and on [http://www.debian.org|Debian 9 "Stretch"].
Some advanced Tcl/Tk extensions from [Batteries Included] are built in: <tt>tkpath</tt>, <tt>tktreectrl</tt>, <tt>tkimg</tt>, and <tt>Canvas3D</tt> (which requires the display driver to support OpenGL 2.x or better). Tcl-only extensions (without machine specific libraries) like <tt>tcllib</tt>, <tt>tksqlite</tt>, and <tt>bwidgets</tt> are included, too.
Some SDL specific command line options described in [Beyond AndroWish] can be used to control the size of the Tk root window or its resizability. Other SDL specific things can be controlled at runtime using the [sdltk command].
In order to start built in scripts directly (which were baked into the ZIP file system), the script to be executed must be specified on the command line with its path within the embedded ZIP file system. Here are some examples.
