teLEaP

tleap (terminal LEAP) is the non-graphical, command-line-only interface to LEAP. It has the same functionality as the xleap main window (Universe Editor Command Window). The user can employ the following terminal keys to edit or enter commands in the tleap interface:

BACKSPACE

The use of this key will cause the last character on the line to be deleted.

uparrow/downarrow

Go backwards and forwards in the command "history" (tleap only).

RETURN/ENTER

Accept the current line. If the current line is the last line of a block then accept the block and execute it. (See the manual section describing the "Universe Editor Command Window".)

control-c

Cancel the current block or terminate the current process.

control-u

Clear the current line.

An edited tleap session is shown below:

In the first line, the user starts the execution of tleap. Several lines of information may then be displayed: the user is first greeted, and if the LEAP script file ("leaprc") contained any commands to load libraries, the execution of these load commands is confirmed. The user may enter commands at the tleap command line prompt ("> "). In the above edited example, the user entered two commands into tleap: "desc ALA" and "quit". After quitting the program, the user is returned to the Unix shell command line prompt.
