 5 | **X** **R**esource **Q**uery,
 6 | A program for querying the X Resources Database from the command line.
 7 | 
 8 | ## Installing
 9 | ```sh
10 | $ git clone https://github.com/arianon/xres
11 | $ cd xres
12 | $ make
13 | $ sudo make install
14 | ```
15 | 
16 | ## Usage
17 | At the computer and time of writing, the following command:
18 | ```sh
19 | $ xrq URxvt.foreground URxvt.background URxvt.font
20 | ```
21 | yields the following values.
22 | ```
23 | #b7bdcc
24 | #14181f
25 | -*-tewi-medium-*-*-*-11-*-*-*-*-*-iso10646-*
26 | ```
27 | 
28 | For querying all 16 colors, one could take advantage of shell expansion.
29 | ```sh
30 | $ xrq URxvt.color{0..15}
31 | ```
32 | yields
33 | ```
34 | #2b303b
35 | #994e55
36 | #849971
37 | #c5aa75
38 | #707e8c
39 | #8f7189
40 | #778f8e
41 | #a6aab2
42 | #4d576b
43 | #bf616a
44 | #a3be8c
45 | #ebcb8b
46 | #8fa1b3
47 | #b48ead
48 | #96b5b4
49 | #b9bbbe
50 | ```
51 | 
52 | If in your `~/.Xresources` or `~/.Xdefaults`, you use glob patterns - such as `*color4: #aabbcc` - you could simply skip the class's name that precedes the resource name. thus the above commands could become this:
53 | 
54 | ```sh
55 | $ xrq color{0..15}
56 | ```
