21 pkgconfdir/config - DisOrder jukebox configuration
23 The purpose of DisOrder is to organize and play digital audio files, under the
24 control of multiple users. \fIpkgconfdir/config\fR is the primary
25 configuration file but this man page currently documents all of its various
28 DisOrder can be configured with multiple collections of tracks, indexing them
29 by their filename, and picking players on the basis of filename patterns (for
32 Although the model is of filenames, it is not inherent that there are
33 corresponding real files - merely that they can be interpreted by the chosen
34 player. See \fBdisorder\fR(3) for more details about this.
36 Each track can have a set of preferences associated with it. These are simple
37 key-value pairs; they can be used for anything you like, but a number of keys
38 have specific meanings. See \fBdisorder\fR(1) for more details about these.
40 Track names are derived from filenames under the control of regular
41 expressions, rather than attempting to interpret format-specific embedded name
42 information. They can be overridden by setting preferences.
44 Names for display are distinguished from names for sorting, so with the right
45 underlying filenames an album can be displayed in its original order even if
46 the displayed track titles are not lexically sorted.
48 A collection of global preferences define various bits of server state: whether
49 random play is enabled, what tags to check for when picking at random, etc.
50 .SS "Users And Access Control"
51 DisOrder distinguishes between multiple users. This is for access control and
52 reporting, not to provide different views of the world: i.e. preferences and so
55 It's possible to restrict a small number of operations to a specific subset of
56 users. However, it is assumed that every user is supposed to be able to do
57 most operations - since the users are all sharing the same audio environment
58 they are expected to cooperate with each other.
60 Access control is entirely used-based. If you configure DisOrder to listen for
61 TCP/IP connections then it will accept a connection from anywhere provided the
62 right password is available. Passwords are never transmitted over TCP/IP
63 connections in clear, but everything else is. The expected model is that
64 host-based access control is imposed at the network layer.
66 The web interface is controlled by a collection of template files, one for each
67 kind of page, and a collection of option files. These are split up and
68 separate from the main configuration file to make it more convenient to
69 override specific bits.
71 The web interface connects to the DisOrder server like any other user, though
72 it is given a special privilege to "become" any other user. (Thus, any process
73 with the same UID as the web interface is very powerful as far as DisOrder
76 Access control to the web interface is (currently) separate from DisOrder's own
77 access control (HTTP authentication is required) but uses the same user
79 .SH "CONFIGURATION FILE"
81 Lines are split into fields separated by whitespace (space, tab, line
82 feed, carriage return, form feed). Comments are started by the number
85 Fields may be unquoted (in which case they may not contain spaces and
86 may not start with a quotation mark or apostrophe) or quoted by either
87 quotation marks or apostrophes. Inside quoted fields every character
88 stands for itself, except that a backslash can only appear as part of
89 one of the following escape sequences:
104 No other escape sequences are allowed.
106 Within any line the first field is a configuration command and any
107 further fields are parameters. Lines with no fields are ignored.
109 After editing the config file use \fBdisorder reconfigure\fR to make
110 it re-read it. If there is anything wrong with it the daemon will
111 record a log message and ignore the new config file. (You should fix
112 it before next terminating and restarting the daemon, as it cannot
113 start up without a valid config file.)
114 .SS "Global Configuration"
116 .B home \fIDIRECTORY\fR
117 The home directory for state files. Defaults to
121 Adds a directory to the plugin path. (This is also used by the web
124 Plugins are opened the first time they are required and never after,
125 so after changing a plugin you must restart the server before it is
126 guaranteed to take effect.
127 .SS "Server Configuration"
129 .B alias \fIPATTERN\fR
130 Defines the pattern use construct virtual filenames from \fBtrackname_\fR
133 Most characters stand for themselves, the exception being \fB{\fR which is used
134 to insert a track name part in the form \fB{\fIname\fB}\fR or
137 The difference is that the first form just inserts the name part while the
138 second prefixes it with a \fB/\fR if it is nonempty.
140 The pattern should not attempt to include the collection root, which is
141 automatically included, but should include the proper extension.
143 The default is \fB{/artist}{/album}{/title}{ext}\fR.
145 .B authorization_algorthm \fIALGORITHM\fR
146 Defines the algorithm used to authenticate clients. The valid options
147 are sha1 (the default), sha256, sha384 and sha512. See
148 .BR disorder_protocol (5)
151 .B broadcast \fIADDRESS\fR \fIPORT\fR
152 Transmit sound data to \fIADDRESS\fR using UDP port \fIPORT\fR. This implies
153 \fBspeaker_backend network\fR.
155 .B broadcast_from \fIADDRESS\fR \fIPORT\fR
156 Sets the (local) source address used by \fBbroadcast\fR.
158 .B channel \fICHANNEL\fR
159 The mixer channel that the volume control should use. Valid names depend on
160 your operating system and hardware, but some standard ones that might be useful
165 Output level for the audio device. This is probably what you want.
168 Output level for the PC speaker, if that is connected to the sound card.
171 Output level for alternative codec device.
174 Master output level. The OSS documentation recommends against using this, as
175 it affects all output devices.
178 You can also specify channels by number, if you know the right value.
180 .B collection \fIMODULE\fR \fIENCODING\fR \fIROOT\fR
181 Define a collection of tracks.
183 \fIMODULE\fR defines which plugin module should be used for this
184 collection. Use the supplied \fBfs\fR module for tracks that exists
185 as ordinary files in the filesystem.
187 \fIENCODING\fR defines the encoding of filenames in this collection.
188 For \fBfs\fR this would be the encoding you use for filenames.
189 Examples might be \fBiso-8859-1\fR or \fButf-8\fR.
191 \fIROOT\fR is the root in the filesystem of the filenames and is
192 passed to the plugin module.
195 ALSA device to play raw-format audio. Default is \fBdefault\fR, i.e. to use
196 the whatever the ALSA configured default is.
199 Specifies the number of seconds to leave between tracks. The default
202 .B history \fIINTEGER\fR
203 Specifies the number of recently played tracks to remember (including
204 failed tracks and scratches).
206 .B listen \fR[\fIHOST\fR] \fISERVICE\fR
207 Listen for connections on the address specified by \fIHOST\fR and port
208 specified by \fISERVICE\fR. If \fIHOST\fR is omitted then listens on all
211 Normally the server only listens on a UNIX domain socket.
214 Determines whether the server locks against concurrent operation. Default is
218 The path to the mixer device, if you want access to the volume control,
219 e.g. \fB/dev/mixer\fR.
221 .B multicast_ttl \fIHOPS\fR
222 Set the maximum number of hops to send multicast packets. This only applies is
223 \fBspeaker_backend\fR is set to \fBnetwork\fR and \fBbroadcast\fR is actually a
226 .B namepart \fIPART\fR \fIREGEXP\fR \fISUBST\fR [\fICONTEXT\fR [\fIREFLAGS\fR]]
227 Determines how to extract trackname part \fIPART\fR from a
228 track name (with the collection root part removed).
229 Used in \fB@recent@\fR, \fB@playing@\fR and \fB@search@\fR.
231 Track names can be different in different contexts. For instance the sort
232 string might include an initial track number, but this would be stripped for
233 the display string. \fICONTEXT\fR should be a glob pattern matching the
234 contexts in which this directive will be used.
236 Valid contexts are \fBsort\fR and \fBdisplay\fR.
238 All the \fBnamepart\fR directives are considered in order. The
239 first directive for the right part, that matches the desired context,
240 and with a \fIREGEXP\fR that
241 matches the track is used, and the value chosen is constructed from
242 \fISUBST\fR according to the substitution rules below.
244 Note that searches use the raw track name and \fBtrackname_\fR preferences but
245 not (currently) the results of \fBnamepart\fR, so generating words via this option
246 that aren't in the original track name will lead to confusing results.
248 If you supply no \fBnamepart\fR directives at all then a default set will be
249 supplied automatically. But if you supply even one then you must supply all of
250 them. See the example config file for the defaults.
252 .B nice_rescan \fIPRIORITY\fR
253 Set the recan subprocess priority. The default is 10.
255 (Note that higher values mean the process gets less CPU time; UNIX priority
256 values are backwards.)
258 .B nice_server \fIPRIORITY\fR
259 Set the server priority. This is applied to the server at startup time (and
260 not when you reload configuration). The server does not use much CPU itself
261 but this value is inherited by programs it executes. If you have limited CPU
262 then it might help to set this to a small negative value. The default is 0.
264 .B nice_speaker \fIPRIORITY\fR
265 Set the speaker process priority. This is applied to the speaker process at
266 startup time (and not when you reload the configuration). The speaker process
267 is not massively CPU intensive by today's standards but depends on reasonably
268 timely scheduling. If you have limited CPU then it might help to set this to a
269 small negative value. The default is 0.
272 The maximum days that a track can survive in the database of newly added
273 tracks. The default is 31.
275 .B player \fIPATTERN\fR \fIMODULE\fR [\fIOPTIONS.. [\fB--\fR]] \fIARGS\fR...
276 Specifies the player for files matching the glob \fIPATTERN\fR. \fIMODULE\fR
277 specifies which plugin module to use.
279 The following options are supported:
282 .B --wait-for-device\fR[\fB=\fIDEVICE\fR]
283 Waits (for up to a couple of seconds) for the default, or specified, libao
284 device to become openable.
287 Defines the end of the list of options. Needed if the first argument to the
288 plugin starts with a "-".
291 The following are the standard modules:
294 .B exec \fICOMMAND\fR \fIARGS\fR...
295 The command is executed via \fBexecvp\fR(3), not via the shell.
296 The \fBPATH\fR environment variable is searched for the executable if it is not
298 The command is expected to know how to open its own sound device.
300 .B execraw \fICOMMAND\fR \fIARGS\fR...
301 Identical to the \fBexec\fR except that the player is expected to use the
302 DisOrder raw player protocol.
303 .BR disorder-decode (8)
304 can decode several common audio file formats to this format. If your favourite
305 format is not supported, but you have a player which uses libao, there is also
306 a libao driver which supports this format; see below for more information about
309 .B shell \fR[\fISHELL\fR] \fICOMMAND\fR
310 The command is executed using the shell. If \fISHELL\fR is specified then that
311 is used, otherwise \fBsh\fR will be used. In either case the \fBPATH\fR
312 environment variable is searched for the shell executable if it is not an
313 absolute path. The track name is stored in the environment variable
316 Be careful of the interaction between the configuration file quoting rules and
317 the shell quoting rules.
320 If multiple player commands match a track then the first match is used.
322 .B prefsync \fISECONDS\fR
323 The interval at which the preferences log file will be synchronised. Defaults
324 to 3600, i.e. one hour.
326 .B queue_pad \fICOUNT\fR
327 The target size of the queue. If random play is enabled then randomly picked
328 tracks will be added until the queue is at least this big.
330 .B sample_format \fIBITS\fB/\fIRATE\fB/\fICHANNELS
331 Describes the sample format expected by the \fBspeaker_command\fR (below). The
332 components of the format specification are as follows:
336 The number of bits per sample. Optionally, may be suffixed by \fBb\fR or
337 \fBl\fR for big-endian and little-endian words. If neither is used the native
338 byte order is assumed.
341 The number of samples per second.
344 The number of channels.
351 Defines the signal to be sent to track player process groups when tracks are
352 scratched. The default is \fBSIGKILL\fR.
354 Signals are specified by their full C name, i.e. \fBSIGINT\fR and not \fBINT\fR
355 or \fBInterrupted\fR or whatever.
357 .B speaker_backend \fINAME\fR
358 Selects the backend use by the speaker process. The following options are
363 Use the ALSA API. This is only available on Linux systems, on which it is the
367 Execute a command. This is the default if
369 is specified, or (currently) on non-Linux systems.
372 Transmit audio over the network. This is the default if
373 \fBbroadcast\fR is specified. You can use
374 .BR disorder-playrtp (1)
375 to receive and play the resulting stream on Linux and OS X.
378 .B sox_generation \fB0\fR|\fB1
379 Determines whether calls to \fBsox\fR(1) should use \fB-b\fR, \fB-x\fR, etc (if
380 the generation is 0) or \fB-\fIbits\fR, \fB-L\fR etc (if it is 1). The default
383 .B speaker_command \fICOMMAND
384 Causes the speaker subprocess to pipe audio data into shell command
385 \fICOMMAND\fR, rather than writing to a local sound card. The sample format is
390 Note that if the sample format is wrong then
392 is invoked to translate it. If
394 is not installed then this will not work.
396 .B restrict \fR[\fBscratch\fR] [\fBremove\fR] [\fBmove\fR]
397 Determine which operations are restricted to the submitter of a
398 track. By default, no operations are restricted, i.e. anyone can
399 scratch or remove anything.
401 If \fBrestrict scratch\fR or \fBrestrict remove\fR are set then only the user
402 that submitted a track can scratch or remove it, respectively.
404 If \fBrestrict move\fR is set then only trusted users can move tracks around in
407 If \fBrestrict\fR is used more than once then only the final use has any
410 .B scratch \fIPATH\fR
411 Specifies a scratch. When a track is scratched, a scratch track is
413 Scratches are played using the same logic as other tracks.
415 At least for the time being, path names of scratches must be encoded using
416 UTF-8 (which means that ASCII will do).
418 .B stopword \fIWORD\fR ...
419 Specifies one or more stopwords that should not take part in searches
421 .SS "Client Configuration"
423 .B connect \fIHOST SERVICE\fR
424 Connect to the address specified by \fIHOST\fR and port specified by
426 .SS "Web Interface Configuration"
428 .B refresh \fISECONDS\fR
429 Specifies the maximum refresh period in seconds. Default 15.
431 .B templates \fIPATH\fR ...
432 Specifies the directory containing templates used by the web
433 interface. If a template appears in more than one template directory
434 then the one in the earliest directory specified is chosen.
436 See below for further details.
438 .B transform \fITYPE\fR \fIREGEXP\fR \fISUBST\fR [\fICONTEXT\fR [\fIREFLAGS\fR]]
439 Determines how names are sorted and displayed in track choice displays.
441 \fITYPE\fR is the type of transformation; usually \fBtrack\fR or
442 \fBdir\fR but you can define your own.
444 \fICONTEXT\fR is a glob pattern matching the context. Standard contexts are
445 \fBsort\fR (which determines how directory names are sorted) and \fBdisplay\fR
446 (which determines how they are displayed). Again, you can define your
449 All the \fBtransform\fR directives are considered in order. If
450 the \fITYPE\fR, \fIREGEXP\fR and the \fICONTEXT\fR match
451 then a new track name is constructed from
452 \fISUBST\fR according to the substitution rules below. If several
453 match then each is executed in order.
455 If you supply no \fBtransform\fR directives at all then a default set will be
456 supplied automatically. But if you supply even one then you must supply all of
457 them. See the example config file for the defaults.
460 Specifies the URL of the web interface. This URL will be used in
463 This must be the full URL, e.g. \fBhttp://myhost/cgi-bin/jukebox\fR and not
464 \fB/cgi-bin/jukebox\fR.
465 .SS "Authentication Configuration"
467 .B allow \fIUSERNAME\fR \fIPASSWORD\fR
468 Specify a username/password pair.
470 .B password \fIPASSWORD\fR
473 .B trust \fIUSERNAME\fR
474 Allow \fIUSERNAME\fR to perform privileged operations such as shutting
475 down or reconfiguring the daemon, or becoming another user.
478 Specifies the user to run as. Only makes sense if invoked as root (or
481 .B username \fIUSERNAME\fR
482 Specify username. The default is taken from the environment variable
485 Configuration files are read in the following order:
489 .I pkgconfdir/config.private
490 Should be readable only by the jukebox group, and contain \fBallow\fR
491 commands for authorised users.
493 .I pkgconfdir/config.\fRUSER
494 Per-user system-controlled client configuration. Optional but if it
495 exists must be readable only by the relevant user. Would normally
496 contain a \fBpassword\fR directive.
498 .I ~\fRUSER\fI/.disorder/passwd
499 Per-user client configuration. Optional but if it exists must be
500 readable only by the relevant user. Would normally contain a
501 \fBpassword\fR directive.
502 .SH "GLOBAL PREFERENCES"
503 These are the values set with \fBset-global\fR.
506 If this is set an nonempty then randomly played tracks will always have at
507 least one of the listed tags.
509 Tags can contain any printing character except comma. Leading and trailing
510 spaces are not significant but internal spaces are. Tags in a list are
514 If this is set an nonempty then randomly played tracks will never have any of
518 If unset or \fByes\fR then play is enabled. Otherwise it is disabled. Use
519 \fBdisable\fR rather than setting it directly.
522 If unset or \fByes\fR then random play is enabled. Otherwise it is disabled.
523 Use \fBdisable\fR rather than setting it directly.
525 .SS "Raw Protocol Players"
526 Raw protocol players are expected to use the \fBdisorder\fR libao driver.
527 Programs that use libao generally have command line options to select the
528 driver and pass options to it.
530 The known driver options are:
533 The file descriptor to write to. If this is not specified then the driver
534 looks like the environment variable \fBDISORDER_RAW_FD\fR. If that is not set
535 then the default is 1 (i.e. standard output).
538 If this is set to a nonzero value then the driver will call \fB_exit\fR(2) if a
539 write to the output file descriptor fails. This is a workaround for buggy
540 players such as \fBogg123\fR that ignore write errors.
542 When \fBdisorder.cgi\fR wants to generate a page for an action it searches the
543 directories specified with \fBtemplates\fR for a matching file. It is
544 suggested that you leave the distributed templates unchanged and put
545 any customisations in an earlier entry in the template path.
547 The supplied templates are:
550 Display information about DisOrder.
553 Navigates through the track database to choose a track to play. The
554 \fBdir\fR argument gives the directory to look in; if it is missing
555 then the root directory is used.
558 Provides a front end to \fBchoose.html\fR which allows subsets of the top level
559 directories to be selected by initial letter.
562 The "front page", which usually shows the currently playing tracks and
564 Gets an HTTP \fBRefresh\fR header.
566 If the \fBmgmt\fR CGI argument is set to \fBtrue\fR then we include extra
567 buttons for moving tracks up and down in the queue. There is some logic in
568 \fBdisorder.cgi\fR to ensure that \fBmgmt=true\fR is preserved across refreshes
569 and redirects back into itself, but URLs embedded in web pages must include it
573 Views preferences. If the \fBfile\fR, \fBname\fR and \fBvalue\fR arguments are
574 all set then that preference is modified; if \fBfile\fR and \fBname\fR are set
575 but not \fBvalue\fR then the preference is deleted.
578 Lists recently played tracks.
581 Presents search results.
584 Primitive volume control.
586 Additionally, other standard files are included by these:
589 Included at the end of the main content \fB<DIV>\fR element.
592 Included at the start of the \fB<BODY>\fR element.
595 Included in the \fB<HEAD>\fR element.
598 Contains the default DisOrder stylesheet. You can override this by editing the
599 CSS or by replacing it all with a \fB<LINK>\fR to an external stylesheet.
601 Templates are ASCII files containing HTML documents, with an expansion
602 syntax to enable data supplied by the implementation to be inserted.
604 If you want to use characters outside the ASCII range, use either the
605 appropriate HTML entity, e.g. \fBé\fR, or an SGML numeric
606 character reference, e.g. \fBý\fR. Use \fB@\fR to insert a
607 literal \fB@\fR without falling foul of the expansion syntax.
608 .SS "Expansion Syntax"
609 Expansions are surrounded by at ("@") symbols take the form of a keyword
610 followed by zero or more arguments. Arguments may either be quoted by curly
611 brackets ("{" and "}") or separated by colons (":"). Both kinds may be mixed
612 in a single expansion, though doing so seems likely to cause confusion.
613 The descriptions below contain suggested forms for each
616 Leading and trailing whitespace in unquoted arguments is ignored, as is
617 whitespace (including newlines) following a close bracket ("}").
619 Arguments are recursively expanded before being interpreted, except for
620 \fITEMPLATE\fR arguments. These are expanded (possibly more than once) to
621 produce the final expansion.
622 (More than once means the same argument being expanded more than once
623 for different tracks or whatever, not the result of the first
624 expansion itself being re-expanded.)
626 Strings constructed by expansions (i.e. not literally copied from the template
627 text) are SGML-quoted: any character which does not stand for itself in #PCDATA
628 or a quoted attribute value is replaced by the appropriate numeric character
631 The exception to this is that such strings are \fInot\fR quoted when they are
632 generated in the expansion of a parameter.
634 In the descriptions below, the current track means the one set by
635 \fB@playing@\fR, \fB@recent@\fR or \fB@queue@\fR, not the one that is playing.
636 If none of these expansions are in force then there is no current track.
637 \fIBOOL\fR should always be either \fBtrue\fR or \fBfalse\fR.
639 The following expansion keywords are defined:
641 .B @#{\fICOMMENT\fB}@
645 The current action. This reports
647 if the action is really
653 .B @and{\fIBOOL\fB}{\fIBOOL\fB}\fR...\fB@
654 If there are no arguments, or all the arguments are \fBtrue\fB, then expands to
655 \fBtrue\fR, otherwise to \fBfalse\fR.
658 Expands to the value of CGI script argument \fINAME\fR.
661 The basename of the current directory component, in \fB@navigate@\fR.
663 .B @basename{\fIPATH\fB}@
664 The base name part of \fIPATH\fR.
666 .B @choose{\fIWHAT\fB}{\fITEMPLATE\fB}@
667 Expands \fITEMPLATE\fR repeatedly for each file or directory under
668 \fB@arg:directory@\fR.
669 \fIWHAT\fR should be either \fBfile\fR or \fBdirectory\fR.
670 Use \fB@file@\fR to get the display name or filename of the file or
672 Usually used in \fBchoose.html\fR.
675 The directory of the current directory component, in \fB@navigate@\fR.
677 .B @dirname{\fIPATH\fB}@
678 The directory part of \fIPATH\fR.
681 Expands to \fBtrue\fR if play is currently enabled, otherwise to \fBfalse\fR.
683 .B @eq{\fIA\fB}{\fIB\fB}
684 Expands to \fBtrue\fR if \fIA\fR and \fIB\fR are identical, otherwise to
688 Expands to the filename of the current file or directory, inside the template
689 argument to \fBchoose\fR.
691 .B @files{\fITEMPLATE\fB}
692 Expands \fITEMPLATE\fB once for each file indicated by the \fBdirectory\fR CGI
693 arg if it is present, or otherwise for the list of files counted by \fBfiles\fR
694 with names \fB0_file\fR, \fB1_file\fR etc.
697 The full path of the current directory component, in \fB@navigate@\fR.
700 The ID of the current track.
702 .B @if{\fIBOOL\fB}{\fITRUEPART\fB}{\fIFALSEPART\fB}@
703 If \fIBOOL\fR expands to \fBtrue\fR then expands to \fITRUEPART\fR, otherwise

706 .B @include:\fIPATH\fR@
707 Include the named file as if it were a template file. If \fIPATH\fR
708 starts with a \fB/\fR then it is used as-is; otherwise, ".html" is

756 Expands to \fBtrue\fR if \fIA\fR and \fIB\fR differ, otherwise to \fBfalse\fR.
759 Expands to the number of files from \fB@files\fR (above).
762 Expands to a string including the time and process ID, intended to be
763 unique across invocations.
766 Expands to \fBfalse\fR if \fIBOOL\fR is \fBtrue\fR, otherwise to
769 .B @or{\fIBOOL\fB}{\fIBOOL\fB}\fR...\fB@
770 If at least one argument is \fBtrue\fB, then expands to \fBtrue\fR, otherwise
774 Expands to \fBeven\fR or \fBodd\fR depending on whether the current track is at
775 an even or odd position in \fB@queue@\fR, \fB@recent@\fR or \fB@files@\fR.
777 .B @part{\fICONTEXT\fB}{\fIPART\fB}@
778 Expands to track name part \fIPART\fR using context \fICONTEXT\fR for the
779 current track. The context may be omitted (and normally would be) and defaults
782 .B @part{\fICONTEXT\fB}{\fIPART\fB}{\fITRACK\fB}@
783 Expands to track name part \fIPART\fR using context \fICONTEXT\fR for
784 \fITRACK\fR. In this usage the context may not be omitted.
787 Expands to \fBtrue\fR if the current track is paused, else \fBfalse\fR.
789 .B @playing{\fITEMPLATE\fB}@
790 Expands \fITEMPLATE\fR using the playing track as the current track.

825 a common value of track part \fIPART\fR.
826 The groups are sorted by the value of the part.
831 within the template will apply to one of the tracks in the group.
833 If \fICONTEXT\fR is specified it should be either \fBsort\fR or \fBdisplay\fR,
834 and determines the context for \fIPART\fR. The default is \fBsort\fR. Usually
835 you want \fBdisplay\fR for everything except the title and \fBsort\fR for the
836 title. If you use \fBsort\fR for artist and album then you are likely to get
840 Expands to the server's version string.
842 .B @shell{\fICOMMAND\fB}@
843 Expands to the output of \fICOMMAND\fR executed via the shell. \fBsh\fR is

848 In \fB@queue@\fR and \fB@recent@\fR, expands to the state of the current
849 track. Otherwise the empty string. Known states are:
853 The player terminated with nonzero status, but not because the track was
857 A scratch, in the queue.
860 No player could be found.
866 A randomly chosen track, in the queue.
869 This track was scratched.
872 An explicitly queued track, in the queue.
875 Some additional states only apply to playing tracks, so will never be seen in
876 the queue or recently-played list:
880 The track has been paused.
883 Interrupted because the server is shutting down.
886 This track is currently playing.
890 Expands to the server statistics.
893 Expands to the URL of the current page. Typically used in

897 argument then it is changed to a fresh value.
902 .B @trackstate{\fIPATH\fB}@
903 Expands to the current track state: \fBplaying\fR if the track is actually
904 playing now, \fBqueued\fR if it is queued or the empty string otherwise.
906 .B @transform{\fIPATH\fB}{\fITYPE\fB}{\fICONTEXT\fB}@
907 Transform a path according to \fBtransform\fR (see above).
908 \fIPATH\fR should be a raw filename (of a track or directory).
909 \fITYPE\fR should be the transform type (e.g. \fItrack\fR or \fIdir\fR).
910 \fICONTEXT\fR should be the context, and can be omitted (the default

928 has not been played yet)
931 Who submitted the current track.
933 This is a file called \fIoptions\fR, searched for in the same manner
934 as templates. It includes numerous options for the control of the web
935 interface. The general syntax is the same as the main configuration
936 file, except that it should be encoded using UTF-8 (though this might
937 change to the current locale's character encoding; stick to ASCII to
940 The shipped \fIoptions\fR file includes four standard options files.
944 The default labels file. You wouldn't normally edit this directly - instead
945 supply your own commands in \fIoptions.user\fR. Have a look at the shipped
946 version of the file for documentation of labels used by the standard templates.
949 A user options file. Here you should put any overrides for the default
950 labels and any extra labels required by your modified templates.
952 Valid directives are:
954 .B columns \fINAME\fR \fIHEADING\fR...
955 Defines the columns used in \fB@playing@\fR and \fB@recent@\fB. \fINAME\fR
956 must be either \fBplaying\fR, \fBrecent\fR or \fBsearch\fR.
957 \fIHEADING\fR... is a list of
958 heading names. If a column is defined more than once then the last definitions
961 The heading names \fBbutton\fR, \fBlength\fR, \fBwhen\fR and \fBwho\fR
964 .B include \fIPATH\fR
965 Includes another file. If \fIPATH\fR starts with a \fB/\fR then it is
966 taken as is, otherwise it is searched for in the template path.
968 .B label \fINAME\fR \fIVALUE\fR
969 Define a label. If a label is defined more than once then the last definition
972 Some labels are defined inside \fBdisorder.cgi\fR and others by the
973 default templates. You can define your own labels and use them inside
976 When an undefined label is expanded, if it has a dot in its name then
977 the part after the final dot is used as its value. Otherwise the
978 whole name is used as the value.
980 Labels are no longer documented here, see the shipped \fIoptions.labels\fR file
982 .SH "REGEXP SUBSTITUTION RULES"
983 Regexps are PCRE regexps, as defined in \fBpcrepattern\fR(3). The
984 only option used is \fBPCRE_UTF8\fR. Remember that the configuration
985 file syntax means you have to escape backslashes and quotes inside
988 In a \fISUBST\fR string the following sequences are interpreted
992 These expand to the first to ninth bracketed subexpression.
995 This expands to the matched part of the subject string.
998 This expands to a single \fB$\fR symbol.
1000 All other pairs starting with \fB$\fR are undefined (and might be used
1001 for something else in the future, so don't rely on the current
1004 If \fBi\fR is present in \fIREFLAGS\fR then the match is case-independent. If
1005 \fBg\fR is present then all matches are replaced, otherwise only the first
1008 What the web interface actually does is terminated by the \fBaction\fR CGI
1009 argument. The values listed below are supported.
1011 Except as specified, all actions redirect back to the \fBplaying.html\fR
1012 template unless the \fBback\fR argument is present, in which case the URL it
1013 gives is used instead.
1015 Redirection to \fBplaying.html\fR preserves \fBmgmt=true\fR if it is present.
1018 Move track \fBid\fR by offset \fBdelta\fR.
1021 Play track \fBfile\fR, or if that is missing then play all the tracks in
1025 Don't change any state, but instead compute a suitable refresh time and include
1026 that in an HTTP header. Expands the \fBplaying.html\fR template rather than
1029 This is the default if \fBaction\fR is missing.
1032 Disables random play.
1035 Enables random play.
1038 Disables play completely.
1044 Pauses the current track.
1047 Remove track \fBid\fR.
1050 Resumes play after a pause.
1053 Scratch the playing track. If \fBid\fR is present it must match the playing
1057 Change the volume by \fBdelta\fR, or if that is missing then set it to the
1058 values of \fBleft\fR and \fBright\fR. Expands to the \fBvolume.html\fR template
1059 rather than redirecting.
1062 Adjust preferences from the \fBprefs.html\fR template (which it then expands
1063 rather than redirecting).
1067 is set then the cooked interface is assumed. The value of
1069 is used to determine which trackname preferences are set. By default the
1071 context is adjusted but this can be overridden with the
1075 argument is checked; if it is set then random play is enabled for that track,
1076 otherwise it is disabled.
1082 arguments are set then they are used to set a single preference.
1084 Otherwise if just the
1086 argument is set then that preference is deleted.
1088 It is recommended that links to the \fBprefs\fR action use \fB@resolve@\fR to
1089 enure that the real track name is always used. Otherwise if the preferences
1090 page is used to adjust a trackname_ preference, the alias may change, leading
1091 to the URL going stale.
1094 This action is generated automatically when an error occurs connecting to the
1095 server. The \fBerror\fR label is set to an indication of what the error is.
1096 .SH "TRACK NAME PARTS"
1097 The traditional track name parts are \fBartist\fR, \fBalbum\fR and \fBtitle\fR,
1098 with the obvious intended meaning. These are controlled by configuration and
1099 by \fBtrackname_\fR preferences.
1101 In addition there are two built-in parts, \fBpath\fR which is the whole path
1102 name and \fBext\fR which is the filename extension, including the initial dot
1103 (or the empty string if there is not extension).
1105 \fBdisorder\fR(1), \fBsox\fR(1), \fBdisorderd\fR(8), \fBdisorder-dump\fR(8),
