15 Multiple buttons can be defined by providing the flag multiple times.
16
17*-c, --config* <path>
18 The config file to use. By default, the following paths are checked:
19 _$HOME/.swaynag/config_, _$XDG\_CONFIG\_HOME/swaynag/config_, and
20 _SYSCONFDIR/swaynag/config_. All flags aside from this one and _debug_ are
21 valid options in the configuration file using the format
22 _long-option=value_. All leading dashes should be omitted and the equals
23 sign is required. See swaynag(5) for more information.
24
25*-d, --debug*
26 Enable debugging.
27
28*-e, --edge* top|bottom

52 Sets the text for the dismiss nagbar button. The default is _X_.
53
54*-t, --type* <type>
55 Set the message type. Two types are created by default _error_ and
56 _warning_. Custom types can be defined in the config file. See
57 _--config_ and swaynag(5) for details. Both of the default types can be

11
12# CONFIG FILE
13
14At the top of the config file, _swaynag_ options can be set using the format
15_long-option=value_. These will be used as default values if _swaynag_ is not
16given the option. This can be useful for setting a preferred font, output, and
17edge.
18
19Below the options, custom types may be defined. To define a type, use the
20following format:
21
22```
23[name-of-type]
24option=value
25```
26
27All colors may be given in the form _RRGGBB_ or _RRGGBBAA_. The following
28colors can be set:
29
30*background=<color>*
31 The background color for _swaynag_.
32
33*border=<color>*
34 The color to use for borders of buttons.
35
36*border-bottom=<color>*
37 The color of the border line at the bottom of _swaynag_.
38
39*button-background=<color>*
40 The background color for the buttons.
41
42*text=<color>*
43 The color of the text.
44
45The following sizing options can also be set:
46
47*border-bottom-size=<size>*
48 Set the thickness of the bottom border.
49
50*message-padding=<padding>*
51 Set the padding for the message.
52
53*details-border-size=<size>*
54 Set the thickness for the details border.
55
56*button-border-size=<size>*
57 Set the thickness for the button border.
58
59*button-gap=<gap>*
60 Set the size of the gap between buttons.
61
62*button-dismiss-gap=<gap>*
63 Set the size of the gap between the dismiss button and another button.
64
65*button-margin-right=<margin>*
66 Set the margin from the right of the dismiss button to edge.
67
68*button-padding=<padding>*
69 Set the padding for the button text.
70
71Additionally, the following options can be assigned a default per-type:
72
73*edge=top|bottom*
74 Set the edge to use.
75
76*font=<font>*
77 Set the font to use.
78
79*output=<output>*
80 Set the output to use. This should be the name of a _xdg\_output_.
