* .Xdefaults

The syntax of an Xdefaults file is as follows:

  [client. | *][{restriction.} | *]resource: value

  client

                The name of the application, some program allow change it by

                '-name' option. This element is optional (can be substituated

                with wildcard).

  restriction

                Class names or name of specific class instance. The classes

                names conventionally start with an upper-case letter.

  resource

                The name of the resource whose value is to be changed.

                Resources are typically lowercase with uppercase

                concatenation.

  value

                The actual value of the resource.

  delimiters

                A period (.) is used to signify each step down into the

                hierarchy. A colon (:) is used to separate the resource

                declaration from the actual value.

Comment start with '!' char and goes up to end of line or C-like /* */.

Use xprop utility to find classes and resources used by application.

To reread your .Xresources file, and throw away your old resources:

  $ xrdb ~/.Xdefaults

To reread your .Xresources file, and keep your old resources:

 $ xrdb -merge ~/.Xdefaults

** Example.

  *foreground: yellow

  XClock*foreground: pink

  Xman*topBox*foreground: blue

** Value types.

*** String.

This can be path specification like '/usr/bin/firefox'.

*** Colors.

For color names see '/usr/lib/X11/rgb.txt'. Also you can use hex

representation #ffffff.

*** Font.

You can use either a full name, a wildcarded specification, or a font alias.

  XTerm*Font: -adobe-courier-bold-r-normal--14-140-75-75-m-90-iso8859-1

  XTerm*Font: *courier-bold-r*140*

  XTerm*Font: 7x14

*** Geometry.

  XCalc*geometry: 120x120-0-0

  XClock*geometry: -50+100

*** Cursor names.

Cursor resources require the name of the file in /usr/include/X11/bitmaps that

contains the cursor you want to use.

  ScoTerm*pointerShape: gumby

*** Pixmaps.

Pixmaps are patterns, like bitmaps, that are used to texture or color an area

on your display. Pixmap resources are specified like cursors or bitmaps.

*** Numebers.

  XLogo*borderWidth: 10

*** Boolean.

Some resources require a boolean value, such as 'true' or 'false', 'yes' or

'no', or 'on' or 'off'.

**  Wildcard matching.

The asterisk can be used as a wildcard, making it easy to write a single rule

that can be applied to many different applications or elements.
