AVAILABILITY

This command is available with the OpenWindows environment. For information about installing OpenWindows, refer to the OpenWindows Installation and Start-Up Guide.

DESCRIPTION

textedit is a window-based XV iew 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 XV iew generic tool arguments described in the XView Reference Manual.

−Ea on|off
−adjust_is_pending_delete

Choose whether or not an adjustment to a selection makes the selection “pending-delete.” The default is off. This option corresponds to, and overrides, the adjust_is_pending_delete Text defaults entry.

−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.

−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_contextlines

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.

−number_of_lines lines

Set the number of lines in the bottom subwindow. The default is 45.

−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.

−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.

−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.

−history_limit max

Set the maximum number of editing operations that can be undone or replayed. The default is 50. Corresponds to history_limit.

−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 descriptions of the basic concepts of OpenWindows, see the OpenWindows User’s Guide.

Signal Processing
If textedit hangs, for whatever reason, you can send a SIGHUP....s0 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
You can specify a number of defaults using the .Xdefaults file that affect the behavior of the text-based facilities. See xview(1) for more detailed information.

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 called Function Keys.

Using a Mouse and Pointer:

Single characters can be selected using the SELECT.
Blocks of text can be selected by selecting a starting point with the SELECT and selecting an ending point with ADJUST.
Or blocks of text can be selected using OPEN LOOK’s wipe through feature by pointing at a beginning character and depressing the select button while moving the pointer to the end of a block of text.
Selections can also be made by sing 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 document 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 secondary 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.

You can make adjusted selections switch to pending-delete using the adjust_is_pending_delete defaults entry, or the −Ea option. In this case, CTRL -Middle makes the selection not pending-delete.

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:

Function Keys
The commands indicated by use of the function keys are:

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

1) Change the value of the .Xdefaults parameter text.extrasMenuFilename to the correct file path.
2) Set the environment variable EXTRASMENU to the file desired.
Note that option 1 overrides option 2 if both are used.
For more information see the DeskSet Environment Reference Guide . See also xview(1).

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 /usr/lib/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 /usr/lib/textswrc is a sample containing a set of useful filters. It is not read automatically.

FILES

/usr/lib/text_extras_menu

Specifies bindings of filters for the extras menu pull-right items
