NAME
werl - The Erlang Emulator
DESCRIPTION
On Windows, the preferred way to start the Erlang system for
interactive use is:
werl <arguments>
This will start Erlang in its own window, with fully func-
tioning command-line editing and scrollbars. All flags
except -oldshell work as they do for the erl command.
Ctrl-C is reserved for copying text to the clipboard (Ctrl-V
to paste). To interrupt the runtime system or the shell
process (depending on what has been specified with the +B
system flag), you should use Ctrl-Break.
In cases where you want to redirect standard input and/or
standard output or use Erlang in a pipeline, the werl is not
suitable, and the erl program should be used instead.
The werl window is in many ways modelled after the xterm
window present on other platforms, as the xterm model fits
well with line oriented command based interaction. This
means that selecting text is line oriented rather than rec-
tangle oriented.
To select text in the werl window , simply press and hold
the left mouse button and drag the mouse over the text you
want to select. If the selection crosses line boundaries,
the selected text will consist of complete lines where
applicable (just like in a word processor). To select more
text than fits in the window, start by selecting a small
portion in the beginning of the text you want, then use the
scrollbar to view the end of the desired selection, point to
it and press the right mouse-button. The whole area between
your first selection and the point where you right-clicked
will be included in the selection.
The selected text is copied to the clipboard by either
pressing Ctrl-C, using the menu or pressing the copy button
in the toolbar.
Pasted text is always inserted at the current prompt posi-
tion and will be interpreted by Erlang as usual keyboard
input.
Previous command lines can be retrieved by pressing the Up
arrow or by pressing Ctrl-P. There is also a drop down box
in the toolbar containing the command history. Selecting a
command in the drop down box will insert it at the prompt,

just as if you used the keyboard to retrieve the command.
Closing the werl window will stop the Erlang emulator.
