NAME
cedit - Invokes the UDC Manager utility
SYNOPSIS
cedit [-h] [-c old_db] [-r ref_db] [cur_db]
OPTIONS
-h Displays the usage message.
-c old_db
Copies and converts old format font file or character attribute
database to the new format used by cedit.
-r ref_db
Sets the reference attribute database rather than using the system
default.
OPERANDS
cur_db
Specifies the UDC attribute database to be edited. If this parameter
is not given, the default user database is used or, if user databases
are not enabled, the system database is used. The location of the
default user and system databases are determined by the entry for the
udc service in the cp_dirs file (see cp_dirs(4)). The default
pathnames are /var/i18n/udc for the system database and ~/.udc for the
user database. When the user pathname field in the udc entry contains a
hyphen (-), user databases are disabled for the system.
DESCRIPTION
The cedit command invokes the UDC Manager utility, which manages the
attributes of user-defined characters (UDCs). You can run UDC Manager to
create or edit a font glyph for the character and to manipulate the
following character attributes:
· Symbolic name
· Bitmap font size (16x18, 24x24, 32x32, 40x40) and style
· Codeset value
· Collating value
· Input key sequences for some of the supported input methods
· Character classes
The actual number and type of character attributes that you can manipulate
for each language depends on the corresponding character configuration
files.
The utility has two modes of operation, menu mode and font-editing mode.
When you start the utility, it is in menu mode. In menu mode, the screen is
divided into 3 parts. The upper half of the screen is the work space for
the menu system. Below that is the status area for showing the current
codeset and language. The bottom two lines form the user input and message
display area.
In menu mode, you manipulate character attributes through menu selections;
however, you cannot create or change the font glyph. To edit the glyph, you
must select the Font item in the Edit menu. This selection changes the
utility to font-editing mode, where you use single and double keystroke
commands for editing. For more information about changing character
attributes and editing font glyphs, see the Menu Mode and Font-Editing Mode
sections in this reference page.
The UDC attribute database is not used directly by system utilities.
Information in this database must be processed by the cgen command to
create data files that are used by system utilities. Refer to cgen(1) for
information about processing information in the UDC attribute database.
Menu Mode
The UDC Manager provides a menu navigation system for command selection and
activation. In the menu mode, there is a horizontal main menu bar at the
top of the screen. This menu bar has several different menu items for you
to select and activate.
A menu item can be in one of the following states:
· inactive
· active
· selected
· activated
An inactive menu item does not have a highlighted and underlined letter and
cannot be selected.
An active menu item has a highlighted and underlined letter and can be
selected. The highlighted letter specifies the hot key for fast selection
and activation of this menu item.
A selected menu item appears in inverse video. It is ready for subsequent
activation.
An activated menu item is the one whose submenu has popped up on the screen
or one whose function has started.
You can use one of two methods to navigate within the menu system. You can
use the four arrow keys to move the location cursor to various parts of the
menu, or you can press the hot key for fast selection and activation of
menu item.
For the horizontal main menu bar, you can press the Down-arrow, Space, or
Return key to activate a selected item. A pull-down submenu appears for the
activated menu item. Pressing the Left-arrow or Right-arrow key selects
and activates the corresponding menu item on the main menu bar. To
activate a selected item in a pull-down menu, you can use either the Return
or the Space key.
When >> characters follow a menu item, activating that item causes a
submenu to pop up. To return to a higher menu level without activating an
item on the current level, press Ctrl/X.
To display help for each menu item, press the Help key.
The main menu bar has the following pull-down menus:
· File
· Edit
· Delete
· Show
· Commands
· Options
· Help
The File menu allows you to exit or quit the UDC Manager as well as change
the reference character attribute database. This menu also lets you save
changes made to the current character or cancel all the changes made to
that character.
The Edit menu allows you to select the current character and edit each
individual attribute of that character. Activation of the Font item
changes the UDC Manager to font-editing mode.
The Delete menu allows you to delete previously defined attributes of the
current character.
The Show menu allows you to show the status and values of character
attributes already defined. (However, you cannot view the font glyph
through this menu.)
The Commands menu lets you scale a number of font records of a certain font
size, list all the characters available in the current database for the
current codeset and language, and copy a number of character records from
the reference character attribute database to the current database.
The Options menu allows you to change the current codeset and language.
These options do not change the language of the utility's user interface.
Your options for the user interface language are limited to English and the
language determined by the locale setting at utility startup time.
The Help menu provides online information about the utility.
For some menu items, a selection list pops up that allows you to choose one
or more of the character attributes. To choose or mark a character
attribute, press the space bar or the Return key.
Font Editing Mode
The UDC Manager provides a full screen font editor for creating and
modifying character font patterns. The following paragraphs give a brief
introduction to the screen layout and features available to the user.
On the top left corner of the font editor, there are three small windows
under the heading "Reference". They are used by the Refer mechanism to
display other font patterns in their real size so that users can use these
fonts as a reference when designing new fonts.
The Display window under the three Refer windows is for displaying, in its
real size, the font currently being edited. The main window on the right
side of the editor is the Edit window on which users can create or modify
fonts using cursor movements and editing functions. Each dot inside the
window represents one pixel. The patterns in the Display and Edit windows
may not match. To make them match, press the DISPLAY key (KP.).
There are four Edit modes (Cursor, Paste, Type, and Wrap) that you can set
to control the characteristics of the editing functions. The Cursor mode
can be ON, OFF, ON/OFF or MOVE and controls whether cursor movement turns
on or off the pixel under the cursor. The Paste mode can be OVERLAY or
OVERWRITE and controls the outcome of paste operation. The Type mode can
be BODY or LETTER and specifies whether a boundary is kept around the
character. The Wrap mode can be ON or OFF to enable or disable wrapping of
the cursor.
There are three buffers in the Font Editor (EDIT, USE, and CUT and PASTE)
that are the areas where bitmaps are saved. The EDIT buffer is the main
buffer where you edit the font glyph. This is the buffer that normally
appears in the Edit window. The USE buffer is the buffer that appears in
the Edit window when the USE function is invoked. The CUT and PASTE buffer
content is not visible, but users can cut a pattern from the EDIT or USE
buffers to this buffer or paste its contents into the EDIT buffer.
Most of the editing functions are invoked by pressing a single key on the
keypad of the keyboard. But some functions are invoked by pressing PF1,
called the GOLD key, and another key. The GOLD key changes the editing
function that is mapped by default to the second key.
The Font Editor also provides a small pop-up menu for the SCALE, USE and
REFER functions. The USE and REFER functions can also be invoked by
keystroke; the SCALE function can only be invoked by menu.
The SCALE function allows users to scale the current font to other sizes
supported by the system.
The USE function allows users to retrieve a font from the character
attribute databases or from one of the Reference windows for a cut and
paste operation.
The REFER function allows users to save either the current edited font or a
font from the one of the databases into one of the three reference windows
in a round-robin fashion.
For more information about each individual function, you can invoke the
HELP function within the Font Editor. The following table specifies the
terminal key bindings for all the editing functions:

Starting an Edit Session
An edit session is normally started by selecting the codeset value of the
UDC character to be edited under the current locale. When you select a
Character item from the Edit menu, you are prompted by a submenu with two
possible choices: edit a new character or edit an existing character. In
either case, you must enter the character's codeset value in hexadecimal.
An error message is displayed if you choose to edit a new character whose
value already exists in the database, or if you choose to edit an existing
character when it doesn't exist in the database.
Under the Japanese locales, automatic UDC code point mapping is performed.
This means that when you enter a new UDC's codeset value for the current
locale, the value is also mapped, whenever possible, to corresponding
values in codesets for other Japanese locales. If you later decide to
modify the codeset value of a Japanese UDC character, you are prompted to
determine if the character value in other codesets should be changed
accordingly.
The following diagram shows the mapping between UDC regions in the four
supported Japanese codesets.
+-----------------+-------------------+-----------------+
| deckanji/ | eucJP | SJIS |
| sdeckanji | | |
+-----------------+-------------------+-----------------+
| 0xA121-0xAA7E | 0xF5A1-0XFEFE | 0xF040-0xF4FC |
| 0xAB21-0xB47E | 0x8FF5A1-0x8FFEFE | 0xF540-0xF9FC |
| 0xB521-0xBA7E | 0x8FEEA1-0x8FF3FE | 0xFA40-0xFCFC |
| 0xBB21-0xBB7E | 0x8FF4A1-0x8FF4FE | ----- |
| 0xBC21-0xFE7E | ----- | ----- |
+-----------------+-------------------+-----------------+
If a value in a particular codeset cannot be mapped to another codeset, the
value is left unchanged or unspecified.
After specifying the codeset value, you can proceed to add, modify, or
delete other editable character attributes. Not all the character
attributes can be edited under any locale. For example, under the Japanese
locales, the collating value and input key sequence for a UDC cannot be
edited.
RESTRICTIONS
The dtterm terminal emulator does not support cedit functions. If you
attempt to use cedit under dtterm, the UDC Manager utility may hang. Use
the dxterm terminal emulator.
