Getting to Know Joe

Who (or what) is Joe?

Joe is the default editor used for all ATS machines. It is perhaps the easiest and fastest editor to learn, and it is the most common editor. Other programs such as elm or nn use the joe editor for editing.

Starting Joe

To start joe, type joe at your prompt (usually mail% on mail or troi% on the academic cluster). To edit a file, type joe filename.

Getting Help

The upper left-hand side of the screen displays the name of the file you are editing and its status (whether the document is modified or not). The upper right-hand side should display the help key. To get help, press the control key () and k, then let go of both keys and press h. This key combination will be written as ^kh. To toggle the help screen off, repeat with ^kh.

Exiting

When done editing your file, ^kx will exit and save. Instead, if you wish to exit without saving, thereby canceling all of your changes, press ^c.

Working with Blocks of Text

You can manipulate large areas of text by defining the beginning and ending of a section and then performing operations on that block.

Mark Beginning

To mark the beginning of a text block, place the cursor where you wish the block to begin and type ^kb.

Mark End

To mark the end of a text block, place the cursor where you wish the block to end and type ^kk.

Now that the block is marked off, you can do the following:

Delete

To delete the text block (or "yank" it), type ^ky.

Move

To move the text of the block to another location (so that it is removed from its original location), move the cursor to the point where you would like to move the text, and type ^km.

Copy Text

To copy the text of the block to another location (without deleting the original text), move the cursor to the point where you would like to insert the copy, and type ^kc.

Write

To write (save) the text of the block to a new file, type ^kw.

Making Joe the Default Editor

For most new users, joe should already be your default editor for programs such as elm and nn. If it is not, you can edit your configuration files to make joe the default:

1. Use joe to edit your .login.local file:

joe ~/.login.local

2. Look for two lines that begin "setenv EDITOR" and "setenv VISUAL." Both of these lines should be in your local login file. Change them so that they look like the ones below. If either or both of the lines are missing, add them exactly as shown below.

setenv EDITOR joe

setenv VISUAL joe

3. Save the changes and exit (control k, then x). The changes will take effect the next time you log in.
