1. Introduction

There is now an additional interface to Ceilidh, which may prove useful under certain circumstances.

Instead of using a menu system, each possible Ceilidh action is available directly as a shell command. Some changes to command names have been essential to avoid clashing with names of existing commands.

A great advantage is that you can logout of the UNIX system, and return at any time. Your Ceilidh commands will not be affected. A disadvantage is that you need to remember the command names, instead of having a menu to prompt you every time.

2. Using the interface

Once you have set up the system (see below), you might type

set.cse pr1 : to set up the "pr1" course
set.unit 5  : to set yourself into unit "2"
vn	    : to view the notes
set.ex 5    : to set into exercise 5
set.prog    : to set up the skeleton
ep	    : (note change) to edit the program

At this stage, you could log out, then log in and carry on with

cm	    : to compile it
sub	    : (note change) to mark and submit it
commands    : list the possible commands
info	    : more information (the old "help")

There is NEVER any need to quit. All sensible commands are available at all times.

Some command names are a little different from the menu options, to avoid clashes with existing commands.

Some exercise commands may behave strangely if no exercise has been set.

3. Using the new interface

You need to have the directory

~ceilidh/bin.cli

in your path. Your teacher will tell you where this directory is on your system. Either insert this directory in your path this by hand, or

• if you use the C-shell, execute

  source ~ceilidh/source.csh
  

  and put this line into your .login file to save having to type it each time you log in; or

• if you use a Bourne shell, execute

  . ~ceilidh/source.sh
  

  and put this line into your .profile file, so that you will not need to execute it by hand each time you log in.

Then type

set.env

to set up the necessary files.

You can then start from

set.cse pr1

as shown above.
