AVAILABILITY
This command is available with the OpenWindows environment. textedit uses the OPEN LOOK Graphical User Interface (GUI). For more information about the OPEN LOOK GUI, refer to the OpenWindows Version 3.1 User’s Guide, the OPEN LOOK Graphical User Interface Functional Specification, and the OPEN LOOK Graphical User Interface Style Guide.
DESCRIPTION
textedit is a window-based XView application that provides both mouse and pointer operations and keyboard accelerators for the editing of text. In general, text editing throughout the OpenWindows user environment uses textedit conventions, both in text display areas such as mail message windows and command panel text fields.
textedit operates via a set of command panel buttons and text fields and a set of menus and submenus accessible from the main editing window.
OPTIONS
generic-tool-arguments
textedit accepts the XView generic tool arguments described in xview(7), with the exception of the arguments for setting the frame label.
−Ei on|off
−auto_indent
Choose whether or not to automatically indent newly-opened lines. The default is off. Corresponds to the auto_indent Text default.
−Eo on|off
−okay_to_overwrite
Set behavior to the Store as New File menu item. If on, a Store as New File to the current file is treated as a Save Current File. If off (the standard default), a Store as New File operation using the current filename results in an error message. Corresponds to Store_self_is_save.
−Er on|off
−read_only
Turn read-only mode on or off. When on, text cannot be modified.
−Ec N
−checkpoint count
Checkpoint after every count editing operation. If count is 0 (the standard default), no checkpointing takes place. Each character typed, each Paste, and each Cut counts as an editing operation. Corresponds to checkpoint_frequency.
−EL lines
−lower_context lines
Specify the minimum number of lines to keep between the caret and the bottom of the text subwindow. The default is 2. Corresponds to lower_context.
−Em pixels
−margin pixels
Set the scrollbar margin width in pixels. The default is 4. Corresponds to left_margin.
−En N
−number_of_lines lines
Set the number of lines in the bottom subwindow. The default is 45.
−ES N
−multi_click_space radius
Set the radius, in pixels, within which clicks must occur to be treated as a multi-click selection. The default is 3 pixels. Corresponds to multi_click_space.
−Et N
−tab_width tabstop
Set the number of SPACE characters displayed per TAB stop. The default is 8. This option has no effect on the characters in the file. Corresponds to tab_width.
−ET N
−multi_click_timeout intrvl
Set the interval, in milliseconds, within which any two clicks must occur to be treated as a multi-click selection. The default is 390 milliseconds. Corresponds to multi_click_timeout.
−Eu N
−history_limit max
Set the maximum number of editing operations that can be undone or replayed. The default is 50. Corresponds to history_limit.
−EU N
−upper_context lines
Set the minimum number of lines to keep between the caret and the top of the text subwindow. The default is 2. Corresponds to upper_context.
USAGE
textedit is part of the OpenWindows user environment. For a description of the basic concepts of OpenWindows, see the OpenWindows Version 3.1 User’s Guide .
Signal Processing
If textedit hangs, for whatever reason, you can send a SIGHUP signal to its process ID, which forces it to write any changes (if possible):
kill −HUP pid
The edits are written to the file textedit.pid in its working directory. If that fails, textedit successively tries to write to a file by that name in /var/tmp, and then /tmp. In addition, whenever textedit catches a fatal signal, such as SIGILL, it tries to write out the edits before aborting.
Defaults Options
There are several dozen user-specified defaults that affect the behavior of the text-based facilities. Important defaults entries in the Text category are:
Edit_back_char Set the character for erasing to the left of the caret. The standard default is DELETE. Note: the tty erase character setting has no effect on textedit. Text-based tools refer only to the defaults database key settings.
Edit_back_word Set the character for erasing the word to the left of the caret. The standard default is Ctrl -W.
Edit_back_line Set the character for erasing all characters to the left of the caret. The standard default is Ctrl -U.
Checkpoint_frequency
If set to 0 (the standard default) no checkpointing is done. For any value greater than zero, a checkpoint is made each time the indicated number of editing operations has been performed since the last checkpoint. Each character typed, each Paste, and each Cut counts as an editing operation. The checkpoint file has a name of the form: filename%%, where filename is the name of the file being edited.
Selections
Selections in textedit are defined as selected portions of text to which editing operations can be applied. For example, a selection can be deleted, moved, copied, etc.
textedit provides two types of selections: primary and secondary. Primary selections allow you to select a set of text on which to perform an editing function. Secondary selections allow you to define a second block of text without undefining your primary text selection or repositioning your cursor. Being able to define two sets of text at once allows you to take advantage of the advanced editing functions described below in the section Keyboard Functions.
Using a Mouse and Pointer:
Single characters can be selected using the SELECT mouse button. Blocks of text can be selected by selecting a starting point with the SELECT mouse button and selecting an ending point with the ADJUST mouse function. Blocks of text can also be selected using OPEN LOOK’s wipe through feature by pointing at a beginning character and depressing the SELECT mouse button while moving the pointer to the end of a block of text. Selections can also be made by clicking (rapidly pressing) the SELECT mouse button. Click once to select a single letter; click twice to select a word; click three times to select a complete line of text; click four times to select the entire document being edited.
Visual Feedback
All primary selections are indicated visually by inverse video of the text selected and are pendingdelete. Pending delete selections are replaced if you type or paste while the text is selected. Secondary selections that are not pending delete are indicated by underlining of the text. Secondary selections that are pending delete are indicated by underlining of the text and strike through of the individual characters.
Secondary Selections
Secondary selections are made using any of the selection methods described above in conjunction with one of the four keyboard functions corresponding to the commands Cut, Find, Paste, or Copy.
Secondary selections are made pending delete by holding down the keyboard function sequence when making the secondary selection. If a secondary selection is pending delete, it is deleted when the keyboard function sequence is released, except in the case of Find, which deselects the secondary selection.
Commands that operate on the primary selection do so even if the primary selection is not in the window that issued the command.
Inserting Text and Command Characters
For the most part, typing any of the standard keys either inserts the corresponding character at the insertion point or erases characters. However, certain key combinations are treated as commands. A couple of the most useful are:
CommandCharacterDescription
Copy-then-PasteMeta-pCopies the primary selection to the insertion point
(through the Clipboard).
Go-to-EOFCtrl-ReturnMoves the insertion point to the end of the text, posi-
tioning the text so that the insertion point is visible.
Keyboard Functions
The commands indicated by use of the keyboard functions are:
Commandx86 Key SequenceDescription
StopEscAborts the current command.
AgainMeta-aRepeats the previous editing sequence since a
primary selection was made.
UndoMeta-zUndoes a prior editing sequence.
FrontMeta-rMakes the window completely visible (or
hides it, if it is already exposed).
CopyMeta-cCopies the primary selection, either to the
Clipboard or at the closest end of the secondary
selection.
OpenMeta-wMakes the window iconic (or normal, if already
iconic).
PasteMeta-vCopies either the secondary selection or the
Clipboard at the insertion point.
FindMeta-fSearches for the pattern specified by, in order, the
secondary selection, the primary selection, or the
Clipboard.
CutMeta-xErases, and moves to the Clipboard, either the
primary or the secondary selection.
HelpF1Produces help text.
Find usually searches the text forwards, towards the end. Holding down the Shift key while invoking Find searches backward through the text, towards the beginning. If the pattern is not found before the search encounters either extreme, it “wraps around” and continues from the other extreme. Find starts the search at the appropriate end of the primary selection, if the primary selection is in the subwindow that the search is made in; otherwise it starts at the insertion point, unless the subwindow cannot be edited, in which case it starts at the beginning of the text.
CTRL-Find invokes the Find and Replace pop-up frame.
Menu Items
File A pull-right menu item for file operations.
Edit A pull-right menu item equivalent of the editing keyboard functions. The Edit submenu provides Again, Undo, Copy, Paste, and Cut (same as the corresponding keyboard functions).
Display A pull-right menu item for controlling the way text is displayed and line display format.
Find A pull-right menu item for find and delimiter matching operations.
Extras A user definable pull-right menu item. The Extras standard submenu is controlled by $OPENWINHOME/lib/locale/<locale>/xview/.text_extras_menu. This file has the same syntax as the .openwin-menu file. See xview(7).
Only those items that are active appear as normal text in the menu; inactive items (which are inappropriate at the time) are “grayed out”.
User Defined Commands
The $OPENWINHOME/lib/locale/<locale>/xview/.text_extras_menu file specifies filter programs that are included in the text subwindow Extras pull-right menu item. The file ~/.textswrc specifies filter programs that are assigned to (available) function keys. These filters are applied to the contents of the primary selection. Their output is entered at the caret.
The file /usr/lib/.textswrc is a sample containing a set of useful filters. It is not read automatically.
FILES
~/.textswrc specifies bindings of filters to function keys
$OPENWINHOME/lib/locale/<locale>/xview/.text_extras_menu
specifies bindings of filters for the extras menu pull-right items
/usr/lib/.textswrc contains useful filters, including shift_lines and capitalize.
filename% prior version of filename is available here after a Save Current File menu operation
textedit.pid edited version of filename; generated in response to fatal internal errors
/tmp/Text∗ editing session logs

DIAGNOSTICS
Cannot open file ’filename’, aborting!
filename does not exist or cannot be read.
textedit produces the following exit status codes:
0 normal termination
1 standard OpenWindows help message was printed
2 help message was requested and printed
3 abnormal termination in response to a signal, usually due to an internal error
4 abnormal termination during initialization, usually due to a missing file or running out of swap space
BUGS
Multi-click to change the current selection does not work for the ADJUST selection.
Handling of long lines is incorrect in certain scrolling situations.
There is no way to replay any editing sequence except the most recent.
