xedit(1X) — Commands

X11R6

NAME

xedit − simple text editor for X

SYNOPSIS

xedit [−toolkitoption...] [filename]

OPTIONS

xedit accepts all of the standard X Toolkit command line options (see X(1X)). The order of the command line options is not important.

filenameSpecifies the file that is to be loaded during start-up. This is the file which will be edited. If a file is not specified, xedit lets you load a file or create a new file after it has started up.

DESCRIPTION

The xedit program provides a window consisting of the following four areas:

Commands Section
A set of commands that allow you to exit xedit, save the file, or load a new file into the edit window.

Message Window
Displays xedit messages. In addition, this window can be used as a scratch pad.

Filename Display
Displays the name of the file currently being edited, and whether this file is Read-Write or Read Only.

Edit Window
Displays the text of the file that you are editing or creating.

EDITING

The Athena Text widget is used for the three sections of this application that allow text input. The characters typed will go to the Text widget that the pointer cursor is currently over. If the pointer cursor is not over a text widget then the keypresses will have no effect on the application. This is also true for the special key sequences that popup dialog widgets, so typing Control-S in the filename widget will enable searching in that widget, not the edit widget.

Both the message window and the edit window will create a scrollbar if the text to display is too large to fit in that window. Horizontal scrolling is not allowed by default, but can be turned on through the Text widget’s resources, see Athena Widget Set for the exact resource definition.

The following keystroke combinations are defined:

Ctrl-a	Beginning Of Line	Meta-b	Backward Word
Ctrl-b	Backward Character	Meta-f	Forward Word
Ctrl-d	Delete Next Character	Meta-i	Insert File
Ctrl-e	End Of Line	Meta-k	Kill To End Of Paragraph

Ctrl-g	Multiply Reset	Meta-v	Previous Page
Ctrl-h	Delete Previous Character	Meta-y	Insert Current Selection

Ctrl-k	Kill To End Of Line	Meta-d	Delete Next Word
Ctrl-l	Redraw Display	Meta-D	Kill Word
Ctrl-m	Newline	Meta-h	Delete
Ctrl-n	Next Line	Meta-H	Backward Kill Word
Ctrl-o	Newline And Backup	Meta-<	Beginning Of File
Ctrl-p	Previous Line	Meta->	End Of File
Ctrl-r	Search/Replace Backward	Meta-]	Forward Paragraph
Ctrl-s	Search/Replace Forward	Meta-[	Backward Paragraph

In addition, the pointer may be used to cut and paste text:

Button 1 Motion           Adjust Selection
Button 1 Up               End Selection (cut)
Button 2 Down             Insert Current Selection (paste)
Button 3 Down             Extend Current Selection
Button 3 Motion           Adjust Selection
Button 3 Up               End Selection (cut)

COMMANDS

Quit
Quits the current editing session. If any changes have not been saved, xedit displays a warning message, allowing the user to save the file.

Save
If file backups are enabled (see RESOURCES, below) xedit stores a copy of the original, unedited file in <prefix>file<suffix>, then overwrites the file with the contents of the edit window. The filename is retrieved from the Text widget directly to the right of the Load button.

Load
Loads the file named in the text widget immediately to the right of the this button and displays it in the Edit window. If the currently displayed file has been modified a warning message will ask the user to save the changes, or press Load again.

RESOURCES

For xedit the available resources are:

enableBackups (Class EnableBackups)
Specifies that, when edits made to an existing file are saved, xedit is to copy the original version of that file to <prefix>file<suffix> before it saves the changes. The default value for this resource is “off,” stating that no backups should be created.

backupNamePrefix (Class BackupNamePrefix)
Specifies a string that is to be prepended to the backup filename. The default is that no string shall be prepended.

backupNameSuffix (Class BackupNameSuffix)
Specifies a string that is to be appended to the backup filename. The default is to use “.BAK” as the suffix.

WIDGETS

In order to specify resources, it is useful to know the hierarchy of the widgets which compose xedit. In the notation below, indentation indicates hierarchical structure. The widget class name is given first, followed by the widget instance name.
