X Resources

NEdit has additional options to those provided in the Preferences menu which are set using X resources. Like most other X programs, NEdit can be customized to vastly unnecessary proportions, from initial window positions down to the font and shadow colors of each individual button (A complete discussion of how to do this is left to books on the X Window System). Key binding (see "Key Binding" is one of the most useful of these resource settable options.

X resources are usually specified in a file called .Xdefaults or .Xresources in your home directory (on VMS this is sys$login:decw$xdefaults.dat). On some systems, this file is read and its information attached to the X server (your screen) when you start X. On other systems, the .Xdefaults file is read each time you run an X program. When X resource values are attached to the X server, changes to the resource file are not available to application programs until you either run the xrdb program with the appropriate file as input, or re-start the X server.

Selected X Resource Names

The following are selected NEdit resource names and default values for NEdit options not settable via the Preferences menu (for preference resource names, see your NEdit preference file):

nedit.bufferMode: True

When set to True, run NEdit in buffer mode. Same as running NEdit with the -buffers command line option.

nedit.tagFile: (not defined) 

This can be the name of a file, or multiple files separated by a colon (:) character, of the type produced by Exuberant Ctags or the Unix ctags command, which NEdit will load at startup time (see ctag support ). The tag file provides a database from which NEdit can automatically open files containing the definition of a particular subroutine or data type.

nedit.alwaysCheckRelativeTagsSpecs: True

When this resource is set to True, and there are tag files specified (with the nedit.tagFile resource, see above) as relative paths, NEdit will evaluate these tag value paths whenever a file is opened. All accessible tag files will be loaded at this time. When this resource value is False, relative path tag specifications will only be evaluated at NEdit startup time.

nedit.shell: /bin/csh 

(Unix systems only) The Unix shell (command interpreter) to use for executing commands from the Shell menu

nedit.wordDelimiters: .,/\\`'!@#%^&*()-=+{}[]":;<>?

The characters, in addition to blanks and tabs, which mark the boundaries between words for the move-by-word (Ctrl+Arrow) and select-word (double click) commands. Note that this default value may be overridden by the setting in Preferences -> Default Settings -> Language Modes....

nedit.remapDeleteKey: False

Setting this resource to True forcibly maps the delete key to backspace. This can be helpful on systems where the bindings have become tangled, and in environments which mix systems with PC style keyboards and systems with DEC and Macintosh keyboards. Theoretically, these bindings should be made using the standard X/Motif mechanisms, outside of NEdit. In practice, some environments where users access several different systems remotely, can be very hard to configure. If you've given up and are using a backspace key halfway off the keyboard because you can't figure out the bindings, set this to True.

nedit.typingHidesPointer: False

Setting this resource to True causes the mouse pointer to be hidden when you type in the text area. As soon as the mouse pointer is moved, it will reappear. This is useful to stop the mouse pointer from obscuring text.

nedit.overrideDefaultVirtualKeyBindings: Auto

Motif uses a virtual key binding mechanism that shares the bindings between different Motif applications. When a first Motif application is started, it installs some default virtual key bindings and any other Motif application that runs afterwards, simply reuses them. Obviously, if the first application installs an invalid set, all others applications may have problems.

In the past, NEdit has been the victim of invalid bindings installed by other applications several times. Through this resource, NEdit can be instructed to ignore the bindings installed by other applications, and use its own private bindings. By default, NEdit tries to detect invalid bindings and ignore them automatically (Auto). Optionally, NEdit can be told to always keep the installed bindings (Never), or to always override them (Always).

nedit.stdOpenDialog: False

Setting this resource to True restores the standard Motif style of Open dialog. NEdit file open dialogs are missing a text field at the bottom of the dialog, where the file name can be entered as a string. The field is removed in NEdit to encourage users to type file names in the list, a non-standard, but much faster method for finding files.

nedit.bgMenuButton: ~Shift~Ctrl~Meta~Alt<Btn3Down>

Specification for mouse button / key combination to post the background menu (in the form of an X translation table event specification). The event specification should be as specific as possible, since it will override less specific translation table entries.

nedit.maxPrevOpenFiles: 30

Number of files listed in the Open Previous sub-menu of the File menu. Setting this to zero disables the Open Previous menu item and maintenance of the NEdit file history file.

nedit.printCommand: (system specific)

Command used by the print dialog to print a file, such as, lp, lpr, etc.. The command must be capable of accepting input via stdin (standard input).

nedit.printCopiesOption: (system specific)

Option name used to specify multiple copies to the print command. If the option should be separated from its argument by a space, leave a trailing space. If blank, no "Number of Copies" item will appear in the print dialog.

nedit.printQueueOption: (system specific)

Option name used to specify a print queue to the print command. If the option should be separated from its argument by a space, leave a trailing space. If blank, no "Queue" item will appear in the print dialog.

nedit.printNameOption: (system specific)

Option name used to specify a job name to the print command. If the option should be separated from its argument by a space, leave a trailing space. If blank, no job or file name will be attached to the print job or banner page.

nedit.printHostOption: (system specific)

Option name used to specify a host name to the print command. If the option should be separated from its argument by a space, leave a trailing space. If blank, no "Host" item will appear in the print dialog.

nedit.printDefaultQueue: (system specific)

The name of the default print queue. Used only to display in the print dialog, and has no effect on printing.

nedit.visualID: Best

If your screen supports multiple visuals (color mapping models), this resource allows you to manually choose among them. The default value of "Best" chooses the deepest (most colors) visual available. Since NEdit does not depend on the specific characteristics of any given color model, Best probably IS the best choice for everyone, and the only reason for setting this resource would be to patch around some kind of X server problem. The resource may also be set to "Default", which chooses the screen's default visual (often a color-mapped, PseudoColor, visual for compatibility with older X applications). It may also be set to a numeric visual-id value (use xdpyinfo to see the list of visuals supported by your display), or a visual class name: PseudoColor, DirectColor, TrueColor, etc..

If you are running under a themed environment (like KDE or CDE) that places its colors in a shallow visual, and you'd rather have that color scheme instead of more colors available, then you may need set the visual to "Default" so that NEdit doesn't choose one with more colors. (The reason for this is: if the "best" visual is not the server's default, then NEdit cannot use the colors provided by your environment. NEdit will fall back to its own default color scheme.)

nedit.installColormap: False

Force the installation of a private colormap. If you have a humble 8-bit color display, and netscape is hogging all of the color cells, you may want to try turning this on. On most systems, this will result in colors flashing wildly when you switch between NEdit and other applications. But a few systems (SGI) have hardware support for multiple simultaneous colormaps, and applications with installed colormaps are well behaved.

nedit.findReplaceUsesSelection: False

Controls if the Find and Replace dialogs are automatically loaded with the contents of the primary selection.

nedit.stickyCaseSenseButton: True

Controls if the "Case Sensitive" buttons in the Find and Replace dialogs and the incremental search bar maintain a separate state for literal and regular expression searches. Moreover, when set to True, by default literal searches are case insensitive and regular expression searches are case sensitive. When set to False, the "Case Sensitive" buttons are independent of the "Regular Expression" toggle.

nedit.printDefaultHost: (system specific)

The node name of the default print host. Used only to display in the print dialog, and has no effect on printing.

nedit.multiClickTime: (system specific)

Maximum time in milliseconds allowed between mouse clicks within double and triple click actions.

nedit.undoModifiesSelection: True

By default, NEdit selects any text inserted or changed through a undo/redo action. Set this resource to False if you don't want your selection to be touched.

nedit*scrollBarPlacement: BOTTOM_LEFT

How scroll bars are placed in NEdit windows, as well as various lists and text fields in the program. Other choices are: BOTTOM_RIGHT, TOP_LEFT, or TOP_RIGHT.

nedit*text.autoWrapPastedText: False

When Auto Newline Wrap is turned on, apply automatic wrapping (which normally only applies to typed text) to pasted text as well.

nedit*text.heavyCursor: False

For monitors with poor resolution or users who have difficulty seeing the cursor, makes the cursor in the text editing area of the window heavier and darker.

nedit*text.cursorVPadding: 0

Number of lines to keep the cursor away from the top or bottom line of the window. Keyboard operations that would cause the cursor to get closer than this distance cause the window to scroll up or down instead, except at the beginning of the file. Mouse operations are not affected.

nedit*text.blinkRate: 500

Blink rate of the text insertion cursor in milliseconds. Set to zero to stop blinking.

nedit*text.Translations:

Modifies key bindings (see below).

nedit*foreground: black

nedit.backlightCharTypes:  0-8,10-31,127:red;9:#dedede;32-126,160-255:#f0f0f0;128-159:orange

NOTE: backlighting is experimental (see "Programming with NEdit").

A string specifying character classes as ranges of ASCII values followed by the color to be used as their background colors. The format is:

low[-high]{,low[-high]}:color{;low-high{,low[-high]}:color}

where low and high are ASCII values.

For example:

    nedit*statsAreaForm*foreground

    nedit*statsAreaForm.foreground

nedit*menuBar

Top-of-window menu-bar.

nedit*textHorScrollBar

Horizontal scroll bar.

nedit*textVertScrollBar
