The purpose of DisOrder is to organize and play digital audio files, under the

+control of multiple users.
+\fIpkgconfdir/config\fR is the primary configuration file; the web interface
+uses a number of others (see \fBdisorder.cgi\fR(8)).
.SS Tracks
DisOrder can be configured with multiple collections of tracks, indexing them
by their filename, and picking players on the basis of filename patterns (for

Although the model is of filenames, it is not inherent that there are
corresponding real files - merely that they can be interpreted by the chosen

-Each track can have a set of preferences associated with it. These are simple
-key-value pairs; they can be used for anything you like, but a number of keys
-have specific meanings. See \fBdisorder\fR(1) for more details about these.
+Each track can have a set of preferences associated with it.
+These are simple key-value pairs; they can be used for anything you
+like, but a number of keys have specific meanings.
+See \fBdisorder\fR(1) for more details about these.
.SS "Track Names"
Track names are derived from filenames under the control of regular
expressions, rather than attempting to interpret format-specific embedded name
-information. They can be overridden by setting preferences.

+They can be overridden by setting preferences.
.PP
Names for display are distinguished from names for sorting, so with the right
underlying filenames an album can be displayed in its original order even if
A collection of global preferences define various bits of server state: whether
random play is enabled, what tags to check for when picking at random, etc.
.SS "Users And Access Control"
-DisOrder distinguishes between multiple users. This is for access control and
-reporting, not to provide different views of the world: i.e. preferences and so
-on are global.
+DisOrder distinguishes between multiple users.
+This is for access control and reporting, not to provide different
+views of the world: i.e. preferences and so on are global.
.PP
-It's possible to restrict a small number of operations to a specific subset of
-users. However, it is assumed that every user is supposed to be able to do
-most operations - since the users are all sharing the same audio environment
-they are expected to cooperate with each other.
+Each user has an associated set of rights which contorl which commands they may
+execute.
+Normally you would give all users most rights, and expect them to
+cooperate (they are after all presumed to be in a shared sound environment).
.PP
-Access control is entirely used-based. If you configure DisOrder to listen for
-TCP/IP connections then it will accept a connection from anywhere provided the
-right password is available. Passwords are never transmitted over TCP/IP
-connections in clear, but everything else is. The expected model is that
-host-based access control is imposed at the network layer.
+The full set of rights are:
+.TP
+.B read
+User can perform read-only operations
+.TP
+.B play
+User can add tracks to the queue
+.TP
+.B "move any"
+User can move any track
+.TP
+.B "move mine"
+User can move their own tracks
+.TP
+.B "move random"

+User can change the volume

+User can perform admin operations
+.TP

+Access control is entirely used-based.
+If you configure DisOrder to listen for TCP/IP connections then it will
+accept a connection from anywhere provided the right password is
+available.

+the network layer.
.SS "Web Interface"
The web interface is controlled by a collection of template files, one for each
-kind of page, and a collection of option files. These are split up and
-separate from the main configuration file to make it more convenient to
-override specific bits.
-.PP
-The web interface connects to the DisOrder server like any other user, though
-it is given a special privilege to "become" any other user. (Thus, any process
-with the same UID as the web interface is very powerful as far as DisOrder
-goes.)
-.PP
-Access control to the web interface is (currently) separate from DisOrder's own
-access control (HTTP authentication is required) but uses the same user
-namespace.

+These are split up and separate from the main configuration file to
+.PP
+See \fBdisorder.cgi\fR(8) for more information.
+.SS "Searching And Tags"
+Search strings contain a list of search terms separated by spaces.
+A search term can either be a single word or a tag, prefixed with "tag:".
+.PP
+Search words are compared without regard to letter case or accents; thus, all
+of the following will be considered to be equal to one another:
+.PP
+.nf
+ LATIN CAPITAL LETTER E
+ LATIN SMALL LETTER E
+ LATIN CAPITAL LETTER E WITH GRAVE
+ LATIN SMALL LETTER E WITH GRAVE
+ LATIN CAPITAL LETTER E plus COMBINING GRAVE ACCENT
+ LATIN SMALL LETTER E plus COMBINING GRAVE ACCENT
+.fi
+.PP
+The same rules apply to tags but in addition leading and trailing whitespace is
+disregarded and all whitespace sequences are treated as equal when they appear
+as internal whitespace.
+.PP
+Where several tags are listed, for instance the tags preference for a track,
+the tags are separated by commas.
+Therefore tags may not contain commas.
.SH "CONFIGURATION FILE"

Lines are split into fields separated by whitespace (space, tab, line

-The shipped \fIoptions\fR file includes four standard options files.
-In order, they are:
-.TP
-.I options.labels
-The default labels file. You wouldn't normally edit this directly - instead
-supply your own commands in \fIoptions.user\fR. Have a look at the shipped
-version of the file for documentation of labels used by the standard templates.
-.TP
-.I options.user
-A user options file. Here you should put any overrides for the default
-labels and any extra labels required by your modified templates.
-.PP
-Valid directives are:
-.TP
-.B columns \fINAME\fR \fIHEADING\fR...
-Defines the columns used in \fB@playing@\fR and \fB@recent@\fB. \fINAME\fR
-must be either \fBplaying\fR, \fBrecent\fR or \fBsearch\fR.
-\fIHEADING\fR... is a list of
-heading names. If a column is defined more than once then the last definitions
-is used.
-.IP
-The heading names \fBbutton\fR, \fBlength\fR, \fBwhen\fR and \fBwho\fR
-are built in.
-.TP
-.B include \fIPATH\fR
-Includes another file. If \fIPATH\fR starts with a \fB/\fR then it is
-taken as is, otherwise it is searched for in the template path.
-.TP
-.B label \fINAME\fR \fIVALUE\fR
-Define a label. If a label is defined more than once then the last definition
-is used.
-.SS Labels
-Some labels are defined inside \fBdisorder.cgi\fR and others by the
-default templates. You can define your own labels and use them inside
-a template.
-.PP
-When an undefined label is expanded, if it has a dot in its name then
-the part after the final dot is used as its value. Otherwise the
-whole name is used as the value.
-.PP
-Labels are no longer documented here, see the shipped \fIoptions.labels\fR file
-instead.

.SH "REGEXP SUBSTITUTION RULES"
-Regexps are PCRE regexps, as defined in \fBpcrepattern\fR(3). The
-only option used is \fBPCRE_UTF8\fR. Remember that the configuration

-quoted strings.

-Except as specified, all actions redirect back to the \fBplaying.html\fR

-.TP 8
-.B "move"
-Move track \fBid\fR by offset \fBdelta\fR.
-.TP
-.B "play"
-Play track \fBfile\fR, or if that is missing then play all the tracks in
-\fBdirectory\fR.
-.TP
-.B "playing"
-Don't change any state, but instead compute a suitable refresh time and include
-that in an HTTP header. Expands the \fBplaying.html\fR template rather than
-redirecting.
-.IP
-This is the default if \fBaction\fR is missing.

-.B "random-disable"
-Disables random play.

-.B "random-enable"
-Enables random play.
-.TP
-.B "disable"
-Disables play completely.
-.TP
-.B "enable"
-Enables play.
-.TP
-.B "pause"
-Pauses the current track.
-.TP
-.B "remove"
-Remove track \fBid\fR.
-.TP
-.B "resume"
-Resumes play after a pause.
-.TP
-.B "scratch"
-Scratch the playing track. If \fBid\fR is present it must match the playing
-track.
-.TP
-.B "volume"
-Change the volume by \fBdelta\fR, or if that is missing then set it to the
-values of \fBleft\fR and \fBright\fR. Expands to the \fBvolume.html\fR template
-rather than redirecting.
-.TP
-.B "prefs"
-Adjust preferences from the \fBprefs.html\fR template (which it then expands
-rather than redirecting).
-.IP
-If
-.B parts
-is set then the cooked interface is assumed. The value of
-.B parts
-is used to determine which trackname preferences are set. By default the
-.B display

-.B random
-argument is checked; if it is set then random play is enabled for that track,
-otherwise it is disabled.

-Otherwise if the
-.B name
-and
-.B value
-arguments are set then they are used to set a single preference.
-.IP
-Otherwise if just the
-.B name
-argument is set then that preference is deleted.
-.IP
-It is recommended that links to the \fBprefs\fR action use \fB@resolve@\fR to
-enure that the real track name is always used. Otherwise if the preferences
-page is used to adjust a trackname_ preference, the alias may change, leading
-to the URL going stale.
-.TP
-.B "error"
-This action is generated automatically when an error occurs connecting to the
-server. The \fBerror\fR label is set to an indication of what the error is.
.SH "TRACK NAME PARTS"
The traditional track name parts are \fBartist\fR, \fBalbum\fR and \fBtitle\fR,
