Demos
Expect for Windows includes a number of demonstration
applications to help you get started. These demos are installed in
the demos\Expect directory beneath the Tcl
installation directory (by default,
C:\Tcl\demos\Expect).
The Remote Ls demo and the Wrap Remote
Ls (both described in the remotels.tcl section below) are also accessible
from the ActiveState Expect for Windows program
group on the Windows Start menu. These are the only demos with
graphical (as opposed to console) interfaces; therefore, they are
the only demos that can be run from the Start menu. The other demos
must be run from the command line. The Wrap Remote
Ls demo requires that the Tcl Dev Kit is
installed, as it uses TclApp for wrapping.
The instructions for running these demos assume that the
Tcl\bin directory is in your system's PATH environment
variable. If this is not the case, in the instructions for running
the demos, substitute the full path to the tclsh
interpreter.

This demo is a simple application that "sings" (types) 99
Bottles of Beer on the Wall in the manner of a singing,
beer-drinking typist, with predictable degradation as more bottles
of beer are consumed.
To run the demo, change to the Expect demos directory (by
default, C:\Tcl\demos\Expect) and enter:
tclsh beer.tcl
Top
This demo retrieves an RFC standard by number from the uunet ftp
archive. Alternatively, the -index switch can be used
to request an index of documents.
To run the demo, change to the Expect demos directory (by
default, C:\Tcl\demos\Expect) and enter:
tclsh ftp-rfc.tcl rfc-number
...or...
tclsh ftp-rfc.tcl -index
Note that individual RFCs and the index are downloaded in
"compress" format (.Z), and must be uncompressed before
reading.
Top
This demo logs in to a remote host and lists the contents of the
current directory. It is fully described in the Expect for Windows Tutorial.
To run the demo, change to the Expect demos directory (by
default, C:\Tcl\demos\Expect) and enter:
tclsh remotels.tcl
This will display a list of the switches that are used for
specifying the host, user name, password, etc.
tkremotels.tcl
This demo is similar to the "remotels.tcl" demo, except it has a
graphical Tk front-end. To run the demo, enter:
wish tkremotels.tcl
Alternatively, from the Windows Start menu, select
ActiveState Expect for Windows | Expect Demos | Remote
Ls.
tkremotels.tpj
If you are using ActiveState's Tcl Dev
Kit, the "tkremotels.tpj" project file can be opened using the
TDK's TclApp.
TclApp uses the project file to build a standalone executable that
contains the tkremotels script.
To open, load the "tkremotels.tpj" project file within TclApp,
or, from the Windows Start menu, select ActiveState Expect
for Windows | Expect Demos | Wrap Remote Ls (which will
automatically launch TclApp).
Top
This demo waits for input from STDIN, aborting if input is not
received with the specified timeout value (which is, by default, 10
seconds).
To run the demo, change to the Expect demos directory (by
default, C:\Tcl\demos\Expect) and enter:
tclsh timed-read.tcl
Top
This demo runs a specified external program for a specified
amount of time. The program is aborted when the specified time is
reached.
To run the demo, change to the Expect demos directory (by
default, C:\Tcl\demos\Expect) and enter:
tclsh timed-read.tcl time(seconds) program program_args
Top
This demo retrieves US weather data from an open server. It
accepts a three-character National Weather Service region code (or
a two-character state code, which returns the associated region
code) as input.
To run the demo, change to the Expect demos directory (by
default, C:\Tcl\demos\Expect) and enter:
tclsh weather.tcl state | region
The two-character state abbreviation (eg CA =
California) returns a list of three-character abbreviations of
National Weather Service regions for that state. The
three-character region abbreviation returns the weather
for that region.
weather.tpj
If you are using ActiveState's Tcl Dev
Kit, the "weather.tpj" project file can be opened using the
TDK's TclApp.
TclApp uses the project file to build a standalone executable that
contains the tkremotels script.
