.SH "NAME"
dome-key-mappings \- Mapping definition syntax for dome\-key
.SH "SYNOPSIS"
.sp
Describes dome\-key\(cqs mapping syntax
.SH "DESCRIPTION"
.sp
The mappings file lives at \fI~/\&.config/dome\-key/mappings\&.dkmap\fR\&. All mappings should be written there\&. Three types of mappings can be defined: maps, commands, and modes\&.
.sp
Maps are used to simulate keyboard keys\&. Commands run shell commands\&. Modes, when activated, enable you to define multiple actions for the same headphone buttons\&.
.SH "SYNTAX"
.sp
Map and command mappings are composed of three parts, each separated by whitespace (one or more spaces or tabs):
.sp
.if n \{\
.RS 4
.\}
.nf
MAP_TYPE TRIGGER ACTION
.fi
.if n \{\
.RE
.\}
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
MAP_TYPE is the kind of action (\fBmap\fR
or
\fBcmd\fR)\&.
.RE
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
TRIGGER is one or more headphone keys (\fB<Up>\fR,
\fB<Play>\fR,
\fB<Down>\fR)\&.
.RE
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
ACTION defines what to do when the headphone keys from TRIGGER are pressed\&.
.RE
.sp
Mappings must be written on a single line\&. No line continuation operator is available\&.
.sp
Comment lines are prefixed with a \(oq#\(cq and must appear on their own line\&. They are not permitted on the same line as mapping definitions\&.
.SS "Map"
.sp
ACTION corresponds to a sequence of keyboard keys that will be pressed virtually\&. For example,
.sp
.if n \{\
.RS 4
.\}
.nf
map <Up> Hello<Enter>
.fi
.if n \{\
.RE
.\}
.sp
will type "Hello" with a newline at the end\&. Simulated keys are pressed in succession as quickly as possible\&. There is no way to wait or sleep between keys\&.
.SS "Command"
.sp
ACTION must be a shell command\&. In:
.sp
.if n \{\
.RS 4
.\}
.nf
cmd <Down> say "Good morning"
.fi
.if n \{\
.RE
.\}
.sp
the \fB/usr/bin/say\fR command will be executed, playing "Good morning" in audible speech\&.
.sp
This map type is useful for running arbitrary code that can\(cqt be expressed by simulating keyboard keys with a \fBmap\fR\&.
.sp
Commands are executed with \fB$SHELL \-c ACTION\fR\&. If \fB$SHELL\fR isn\(cqt set, \fB/bin/sh\fR is used instead\&.
.SS "Mode"
.sp
You can think of modes like Vim modes\&. They enable you to map the same trigger more than once\&. Let\(cqs look at an example:
.sp
.if n \{\
.RS 4
.\}
.nf
cmd <Play> open \-a Firefox
.fi
.if n \{\
.RE
.\}
.sp
.if n \{\
.RS 4
.\}
.nf
mode <Up> {
        map <Play> <Space>
}
.fi
.if n \{\
.RE
.\}
.sp
Here, the \fB<Play>\fR headphone button will open Firefox\&. But when the mode is active, pressing \fB<Play>\fR instead simulates the Space key\&.
.sp
Modes are both activated and deactivated by pressing the TRIGGER sequence written after the \fBmode\fR keyword\&. The trigger functions as a toggle\&. In our example, pressing \fB<Up>\fR activates the mode\&. If the mode is active, pressing \fB<Up>\fR will deactivate the mode, causing top\-level mappings to become available again\&.
.sp
Any number of maps and commands can be defined inside a mode\&. These are enclosed by curly braces\&. Mode mappings should not use the same trigger as the mode\(cqs\&. Mappings with the same trigger are ignored:
.sp
.if n \{\
.RS 4
.\}
.nf
mode <Play> {
        # The following mapping is ignored:
        map <Play> Hello
}
.fi
.if n \{\
.RE
.\}
.sp
Modes cannot be nested\&.
.SS "Special Keys"
.sp
Special keys are enclosed in \(oq<\(cq \(oq>\(cq brackets (e\&.g\&. \fB<Play>\fR)\&. These are used in \fBmap\fR actions to simulate a key press\&.
.PP

.RS 4
Unmaps a trigger\&. Used to remove the default behaviour of a trigger button without remapping it\&.

\fBEscaping\fR
.RS 4
.sp
To simulate a literal \(oq<\(cq character, it must be escaped with a backslash\&. Because backslash is used as an escape prefix, literal backslashes must also be escaped with a backslash\&.
.sp

.SS "Modifiers"
.sp
Modifiers can be applied to any key used in \fBmap\fR actions\&. Modifiers can also be chained\&. Modifiers must be prefixed to the key they\(cqre modifying, both of which are surrounded by \(oq<\(cq \(oq>\(cq brackets\&.
