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 the xview(7) man page 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),
Store as New File operations 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 selec-
tion. 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.
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 work-
ing 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. See xview(7) for
a complete description. Important defaults entries in the
Text category are:
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 exam-
ple, 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 reposi-
tioning 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 called Function
Keys.
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 button.
Or blocks of text can be selected using OPEN
LOOK's wipe through feature by pointing at a
beginning character and depressing the SELECT but-
ton while moving the pointer to the end of a block
of text.
Selections can also be made by clicking (rapidly
pressing) the SELECT 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 docu-
ment being edited.
Visual Feedback
All primary selections are indicated visually by
inverse video of the text selected and are pending
delete. 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 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 addition to holding down one of
the four function keys corresponding to the commands Cut,
Find, Paste, or Copy.
Secondary selections are made pending delete by holding the
CTRL key when making the secondary selection. If a secon-
dary selection is pending-delete, it is deleted when the
function key is released, except in the case of the 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. Some of the most useful are:
Command Character Description
Cut-Primary META-X Erases the primary selection and moves it to the
Clipboard.
Find-Primary META-F Searches the text for the pattern specified by the
primary selection or by the Clipboard, if there is no
primary selection.
Copy-to-Clipboard META-C Copies the primary selection to the Clipboard.
Paste-Clipboard META-V Inserts the Clipboard contents at the insertion point.
Copy-then-Paste META-P Copies the primary selection to the insertion point
(through the Clipboard).
Go-to-EOF CTRL-RETURN Moves the insertion point to the end of the text and
positions the text so the insertion point is visible.
Keyboard Functions
The commands indicated by use of the function keys are:
Command SPARC x86 Description
Stop L1 Esc Aborts the current command.
Again L2 Meta-a Repeats the previous editing sequence since a
primary selection was made.
Undo L4 Meta-z Undoes a prior editing sequence.
Front L5 Meta-r Makes the window completely visible (or hides it,
if it is already exposed).
Copy L6 Meta-c Copies the primary selection, either to the
Clipboard or at the closest end of the secondary
selection.
Open L7 Meta-w Makes the window iconic (or normal, if it is already
iconic).
Paste L8 Meta-v Copies either the secondary selection or the Clipboard
at the insertion point.
Find L9 Meta-f Searches for the pattern specified by, in order, the
secondary selection, the primary selection, or the
Clipboard.
Cut L10 Meta-x Erases either the primary or the secondary selection
and moves it to the Clipboard.
Help F1 F1 Produces 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
function keys. The Edit submenu provides Again,
Undo, Copy, Paste, and Cut (same as function keys
L2, L4, L6, L8, and L10).
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 .openwin-menu
file. See the xview man page.
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 file
$OPENWINHOME/lib/locale/<locale>/xview/.text_extras_menu
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
$OPENWINHOME/share/src/xview/examples/textsw/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
$OPENWINHOME/share/src/xview/examples/textsw/textswrc
contains useful filters, including
shift_lines and capitalize.
filename% prior version of filename is avail-
able 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, usu-
ally due to an internal error
4 abnormal termination during initialization, usu-
ally due to a missing file or running out of swap
space
BUGS
Multi-click to change the current selection does not work
for 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.
NOTES
The OpenWindows environment may no longer be supported in a
future release. You may want to migrate to CDE, the Common
Desktop Environment.
