22 pkgconfdir/config - DisOrder jukebox configuration
24 The purpose of DisOrder is to organize and play digital audio files, under the
25 control of multiple users. \fIpkgconfdir/config\fR is the primary
26 configuration file but this man page currently documents all of its various
29 DisOrder can be configured with multiple collections of tracks, indexing them
30 by their filename, and picking players on the basis of filename patterns (for
33 Although the model is of filenames, it is not inherent that there are
34 corresponding real files - merely that they can be interpreted by the chosen
35 player. See \fBdisorder\fR(3) for more details about this.
37 Each track can have a set of preferences associated with it. These are simple
38 key-value pairs; they can be used for anything you like, but a number of keys
39 have specific meanings. See \fBdisorder\fR(1) for more details about these.
41 Track names are derived from filenames under the control of regular
42 expressions, rather than attempting to interpret format-specific embedded name
43 information. They can be overridden by setting preferences.
45 Names for display are distinguished from names for sorting, so with the right
46 underlying filenames an album can be displayed in its original order even if
47 the displayed track titles are not lexically sorted.
49 A collection of global preferences define various bits of server state: whether
50 random play is enabled, what tags to check for when picking at random, etc.
51 .SS "Users And Access Control"
52 DisOrder distinguishes between multiple users. This is for access control and
53 reporting, not to provide different views of the world: i.e. preferences and so
56 It's possible to restrict a small number of operations to a specific subset of
57 users. However, it is assumed that every user is supposed to be able to do
58 most operations - since the users are all sharing the same audio environment
59 they are expected to cooperate with each other.
61 Access control is entirely used-based. If you configure DisOrder to listen for
62 TCP/IP connections then it will accept a connection from anywhere provided the
63 right password is available. Passwords are never transmitted over TCP/IP
64 connections in clear, but everything else is. The expected model is that
65 host-based access control is imposed at the network layer.
67 The web interface is controlled by a collection of template files, one for each
68 kind of page, and a collection of option files. These are split up and
69 separate from the main configuration file to make it more convenient to
70 override specific bits.
72 The web interface connects to the DisOrder server like any other user, though
73 it is given a special privilege to "become" any other user. (Thus, any process
74 with the same UID as the web interface is very powerful as far as DisOrder
77 Access control to the web interface is (currently) separate from DisOrder's own
78 access control (HTTP authentication is required) but uses the same user
80 .SH "CONFIGURATION FILE"
82 Lines are split into fields separated by whitespace (space, tab, line
83 feed, carriage return, form feed). Comments are started by the number
86 Fields may be unquoted (in which case they may not contain spaces and
87 may not start with a quotation mark or apostrophe) or quoted by either
88 quotation marks or apostrophes. Inside quoted fields every character
89 stands for itself, except that a backslash can only appear as part of
90 one of the following escape sequences:
105 No other escape sequences are allowed.
107 Within any line the first field is a configuration command and any
108 further fields are parameters. Lines with no fields are ignored.
110 After editing the config file use \fBdisorder reconfigure\fR to make
111 it re-read it. If there is anything wrong with it the daemon will
112 record a log message and ignore the new config file. (You should fix
113 it before next terminating and restarting the daemon, as it cannot
114 start up without a valid config file.)
115 .SS "Global Configuration"
117 .B home \fIDIRECTORY\fR
118 The home directory for state files. Defaults to
120 The server will create this directory on startup if it does not exist.
123 Adds a directory to the plugin path. (This is also used by the web
126 Plugins are opened the first time they are required and never after,
127 so after changing a plugin you must restart the server before it is
128 guaranteed to take effect.
129 .SS "Server Configuration"
131 .B alias \fIPATTERN\fR
132 Defines the pattern use construct virtual filenames from \fBtrackname_\fR
135 Most characters stand for themselves, the exception being \fB{\fR which is used
136 to insert a track name part in the form \fB{\fIname\fB}\fR or
139 The difference is that the first form just inserts the name part while the
140 second prefixes it with a \fB/\fR if it is nonempty.
142 The pattern should not attempt to include the collection root, which is
143 automatically included, but should include the proper extension.
145 The default is \fB{/artist}{/album}{/title}{ext}\fR.
147 .B authorization_algorthm \fIALGORITHM\fR
148 Defines the algorithm used to authenticate clients. The valid options
149 are sha1 (the default), sha256, sha384 and sha512. See
150 .BR disorder_protocol (5)
153 .B broadcast \fIADDRESS\fR \fIPORT\fR
154 Transmit sound data to \fIADDRESS\fR using UDP port \fIPORT\fR. This implies
155 \fBspeaker_backend network\fR.
157 .B broadcast_from \fIADDRESS\fR \fIPORT\fR
158 Sets the (local) source address used by \fBbroadcast\fR.
160 .B channel \fICHANNEL\fR
161 The mixer channel that the volume control should use. Valid names depend on
162 your operating system and hardware, but some standard ones that might be useful
167 Output level for the audio device. This is probably what you want.
170 Output level for the PC speaker, if that is connected to the sound card.
173 Output level for alternative codec device.
176 Master output level. The OSS documentation recommends against using this, as
177 it affects all output devices.
180 You can also specify channels by number, if you know the right value.
182 .B collection \fIMODULE\fR \fIENCODING\fR \fIROOT\fR
183 Define a collection of tracks.
185 \fIMODULE\fR defines which plugin module should be used for this
186 collection. Use the supplied \fBfs\fR module for tracks that exists
187 as ordinary files in the filesystem.
189 \fIENCODING\fR defines the encoding of filenames in this collection.
190 For \fBfs\fR this would be the encoding you use for filenames.
191 Examples might be \fBiso-8859-1\fR or \fButf-8\fR.
193 \fIROOT\fR is the root in the filesystem of the filenames and is
194 passed to the plugin module.
197 ALSA device to play raw-format audio. Default is \fBdefault\fR, i.e. to use
198 the whatever the ALSA configured default is.
201 Specifies the number of seconds to leave between tracks. The default
204 .B history \fIINTEGER\fR
205 Specifies the number of recently played tracks to remember (including
206 failed tracks and scratches).
208 .B listen \fR[\fIHOST\fR] \fISERVICE\fR
209 Listen for connections on the address specified by \fIHOST\fR and port
210 specified by \fISERVICE\fR. If \fIHOST\fR is omitted then listens on all
213 Normally the server only listens on a UNIX domain socket.
216 Determines whether the server locks against concurrent operation. Default is
220 The path to the mixer device, if you want access to the volume control,
221 e.g. \fB/dev/mixer\fR.
223 .B multicast_ttl \fIHOPS\fR
224 Set the maximum number of hops to send multicast packets. This only applies is
225 \fBspeaker_backend\fR is set to \fBnetwork\fR and \fBbroadcast\fR is actually a
228 .B namepart \fIPART\fR \fIREGEXP\fR \fISUBST\fR [\fICONTEXT\fR [\fIREFLAGS\fR]]
229 Determines how to extract trackname part \fIPART\fR from a
230 track name (with the collection root part removed).
231 Used in \fB@recent@\fR, \fB@playing@\fR and \fB@search@\fR.
233 Track names can be different in different contexts. For instance the sort
234 string might include an initial track number, but this would be stripped for
235 the display string. \fICONTEXT\fR should be a glob pattern matching the
236 contexts in which this directive will be used.
238 Valid contexts are \fBsort\fR and \fBdisplay\fR.
240 All the \fBnamepart\fR directives are considered in order. The
241 first directive for the right part, that matches the desired context,
242 and with a \fIREGEXP\fR that
243 matches the track is used, and the value chosen is constructed from
244 \fISUBST\fR according to the substitution rules below.
246 Note that searches use the raw track name and \fBtrackname_\fR preferences but
247 not (currently) the results of \fBnamepart\fR, so generating words via this option
248 that aren't in the original track name will lead to confusing results.
250 If you supply no \fBnamepart\fR directives at all then a default set will be
251 supplied automatically. But if you supply even one then you must supply all of
252 them. See the example config file for the defaults.
254 .B nice_rescan \fIPRIORITY\fR
255 Set the recan subprocess priority. The default is 10.
257 (Note that higher values mean the process gets less CPU time; UNIX priority
258 values are backwards.)
260 .B nice_server \fIPRIORITY\fR
261 Set the server priority. This is applied to the server at startup time (and
262 not when you reload configuration). The server does not use much CPU itself
263 but this value is inherited by programs it executes. If you have limited CPU
264 then it might help to set this to a small negative value. The default is 0.
266 .B nice_speaker \fIPRIORITY\fR
267 Set the speaker process priority. This is applied to the speaker process at
268 startup time (and not when you reload the configuration). The speaker process
269 is not massively CPU intensive by today's standards but depends on reasonably
270 timely scheduling. If you have limited CPU then it might help to set this to a
271 small negative value. The default is 0.
274 The maximum days that a track can survive in the database of newly added
275 tracks. The default is 31.
277 .B player \fIPATTERN\fR \fIMODULE\fR [\fIOPTIONS.. [\fB--\fR]] \fIARGS\fR...
278 Specifies the player for files matching the glob \fIPATTERN\fR. \fIMODULE\fR
279 specifies which plugin module to use.
281 The following options are supported:
284 .B --wait-for-device\fR[\fB=\fIDEVICE\fR]
285 Waits (for up to a couple of seconds) for the default, or specified, libao
286 device to become openable.
289 Defines the end of the list of options. Needed if the first argument to the
290 plugin starts with a "-".
293 The following are the standard modules:
296 .B exec \fICOMMAND\fR \fIARGS\fR...
297 The command is executed via \fBexecvp\fR(3), not via the shell.
298 The \fBPATH\fR environment variable is searched for the executable if it is not
300 The command is expected to know how to open its own sound device.
302 .B execraw \fICOMMAND\fR \fIARGS\fR...
303 Identical to the \fBexec\fR except that the player is expected to use the
304 DisOrder raw player protocol.
305 .BR disorder-decode (8)
306 can decode several common audio file formats to this format. If your favourite
307 format is not supported, but you have a player which uses libao, there is also
308 a libao driver which supports this format; see below for more information about
311 .B shell \fR[\fISHELL\fR] \fICOMMAND\fR
312 The command is executed using the shell. If \fISHELL\fR is specified then that
313 is used, otherwise \fBsh\fR will be used. In either case the \fBPATH\fR
314 environment variable is searched for the shell executable if it is not an
315 absolute path. The track name is stored in the environment variable
318 Be careful of the interaction between the configuration file quoting rules and
319 the shell quoting rules.
322 If multiple player commands match a track then the first match is used.
324 .B prefsync \fISECONDS\fR
325 The interval at which the preferences log file will be synchronised. Defaults
326 to 3600, i.e. one hour.
328 .B queue_pad \fICOUNT\fR
329 The target size of the queue. If random play is enabled then randomly picked
330 tracks will be added until the queue is at least this big.
332 .B sample_format \fIBITS\fB/\fIRATE\fB/\fICHANNELS
333 Describes the sample format expected by the \fBspeaker_command\fR (below). The
334 components of the format specification are as follows:
338 The number of bits per sample. Optionally, may be suffixed by \fBb\fR or
339 \fBl\fR for big-endian and little-endian words. If neither is used the native
340 byte order is assumed.
343 The number of samples per second.
346 The number of channels.
353 backend the sample format is forced to
357 backend it is forced to
359 in both cases regardless of what is specified in the configuration file.
363 Defines the signal to be sent to track player process groups when tracks are
364 scratched. The default is \fBSIGKILL\fR.
366 Signals are specified by their full C name, i.e. \fBSIGINT\fR and not \fBINT\fR
367 or \fBInterrupted\fR or whatever.
369 .B speaker_backend \fINAME\fR
370 Selects the backend use by the speaker process. The following options are
375 Use the ALSA API. This is only available on Linux systems, on which it is the
379 Use Apple Core Audio. This only available on OS X systems, on which it is the
383 Use the OSS (/dev/dsp) API. Not available on all platforms. Not well
384 maintained at the moment.
387 Execute a command. This is the default if
389 is specified, or if no native is available.
392 Transmit audio over the network. This is the default if
393 \fBbroadcast\fR is specified. You can use
394 .BR disorder-playrtp (1)
395 to receive and play the resulting stream on Linux and OS X.
398 .B sox_generation \fB0\fR|\fB1
399 Determines whether calls to \fBsox\fR(1) should use \fB-b\fR, \fB-x\fR, etc (if
400 the generation is 0) or \fB-\fIbits\fR, \fB-L\fR etc (if it is 1). The default
403 .B speaker_command \fICOMMAND
404 Causes the speaker subprocess to pipe audio data into shell command
405 \fICOMMAND\fR, rather than writing to a local sound card. The sample format is
410 Note that if the sample format is wrong then
412 is invoked to translate it. If
414 is not installed then this will not work.
416 .B restrict \fR[\fBscratch\fR] [\fBremove\fR] [\fBmove\fR]
417 Determine which operations are restricted to the submitter of a
418 track. By default, no operations are restricted, i.e. anyone can
419 scratch or remove anything.
421 If \fBrestrict scratch\fR or \fBrestrict remove\fR are set then only the user
422 that submitted a track can scratch or remove it, respectively.
424 If \fBrestrict move\fR is set then only trusted users can move tracks around in
427 If \fBrestrict\fR is used more than once then only the final use has any
430 .B scratch \fIPATH\fR
431 Specifies a scratch. When a track is scratched, a scratch track is
433 Scratches are played using the same logic as other tracks.
435 At least for the time being, path names of scratches must be encoded using
436 UTF-8 (which means that ASCII will do).
438 .B stopword \fIWORD\fR ...
439 Specifies one or more stopwords that should not take part in searches
441 .SS "Client Configuration"
443 .B connect \fIHOST SERVICE\fR
444 Connect to the address specified by \fIHOST\fR and port specified by
446 .SS "Web Interface Configuration"
448 .B refresh \fISECONDS\fR
449 Specifies the maximum refresh period in seconds. Default 15.
451 .B short_display \fICHARACTERS\fR
452 Defines the maximum number of characters to include in a \fBshort\fR name
455 .B templates \fIPATH\fR ...
456 Specifies the directory containing templates used by the web
457 interface. If a template appears in more than one template directory
458 then the one in the earliest directory specified is chosen.
460 See below for further details.
462 .B transform \fITYPE\fR \fIREGEXP\fR \fISUBST\fR [\fICONTEXT\fR [\fIREFLAGS\fR]]
463 Determines how names are sorted and displayed in track choice displays.
465 \fITYPE\fR is the type of transformation; usually \fBtrack\fR or
466 \fBdir\fR but you can define your own.
468 \fICONTEXT\fR is a glob pattern matching the context. Standard contexts are
469 \fBsort\fR (which determines how directory names are sorted) and \fBdisplay\fR
470 (which determines how they are displayed). Again, you can define your
473 All the \fBtransform\fR directives are considered in order. If
474 the \fITYPE\fR, \fIREGEXP\fR and the \fICONTEXT\fR match
475 then a new track name is constructed from
476 \fISUBST\fR according to the substitution rules below. If several
477 match then each is executed in order.
479 If you supply no \fBtransform\fR directives at all then a default set will be
480 supplied automatically. But if you supply even one then you must supply all of
481 them. See the example config file for the defaults.
484 Specifies the URL of the web interface. This URL will be used in
487 This must be the full URL, e.g. \fBhttp://myhost/cgi-bin/jukebox\fR and not
488 \fB/cgi-bin/jukebox\fR.
489 .SS "Authentication Configuration"
491 .B allow \fIUSERNAME\fR \fIPASSWORD\fR
492 Specify a username/password pair.
494 .B password \fIPASSWORD\fR
497 .B trust \fIUSERNAME\fR
498 Allow \fIUSERNAME\fR to perform privileged operations such as shutting
499 down or reconfiguring the daemon, or becoming another user.
502 Specifies the user to run as. Only makes sense if invoked as root (or
505 .B username \fIUSERNAME\fR
506 Specify username. The default is taken from the environment variable
509 Configuration files are read in the following order:
513 .I pkgconfdir/config.private
514 Should be readable only by the jukebox group, and contain \fBallow\fR
515 commands for authorised users.
517 If this file does not exist at startup then the server will create it with a
518 randomly chosen password for the root user.
520 .I pkgconfdir/config.\fRUSER
521 Per-user system-controlled client configuration. Optional but if it
522 exists must be readable only by the relevant user. Would normally
523 contain a \fBpassword\fR directive.
525 .I ~\fRUSER\fI/.disorder/passwd
526 Per-user client configuration. Optional but if it exists must be
527 readable only by the relevant user. Would normally contain a
528 \fBpassword\fR directive.
529 .SH "GLOBAL PREFERENCES"
530 These are the values set with \fBset-global\fR.
533 If this is set an nonempty then randomly played tracks will always have at
534 least one of the listed tags.
536 Tags can contain any printing character except comma. Leading and trailing
537 spaces are not significant but internal spaces are. Tags in a list are
541 If this is set an nonempty then randomly played tracks will never have any of
545 If unset or \fByes\fR then play is enabled. Otherwise it is disabled. Use
546 \fBdisable\fR rather than setting it directly.
549 If unset or \fByes\fR then random play is enabled. Otherwise it is disabled.
550 Use \fBdisable\fR rather than setting it directly.
552 .SS "Raw Protocol Players"
553 Raw protocol players are expected to use the \fBdisorder\fR libao driver.
554 Programs that use libao generally have command line options to select the
555 driver and pass options to it.
557 The known driver options are:
560 The file descriptor to write to. If this is not specified then the driver
561 looks like the environment variable \fBDISORDER_RAW_FD\fR. If that is not set
562 then the default is 1 (i.e. standard output).
565 If this is set to a nonzero value then the driver will call \fB_exit\fR(2) if a
566 write to the output file descriptor fails. This is a workaround for buggy
567 players such as \fBogg123\fR that ignore write errors.
569 When \fBdisorder.cgi\fR wants to generate a page for an action it searches the
570 directories specified with \fBtemplates\fR for a matching file. It is
571 suggested that you leave the distributed templates unchanged and put
572 any customisations in an earlier entry in the template path.
574 The supplied templates are:
577 Display information about DisOrder.
580 Navigates through the track database to choose a track to play. The
581 \fBdir\fR argument gives the directory to look in; if it is missing
582 then the root directory is used.
585 Provides a front end to \fBchoose.html\fR which allows subsets of the top level
586 directories to be selected by initial letter.
589 Lists newly added tracks.
592 The "front page", which usually shows the currently playing tracks and
594 Gets an HTTP \fBRefresh\fR header.
596 If the \fBmgmt\fR CGI argument is set to \fBtrue\fR then we include extra
597 buttons for moving tracks up and down in the queue. There is some logic in
598 \fBdisorder.cgi\fR to ensure that \fBmgmt=true\fR is preserved across refreshes
599 and redirects back into itself, but URLs embedded in web pages must include it
603 Views preferences. If the \fBfile\fR, \fBname\fR and \fBvalue\fR arguments are
604 all set then that preference is modified; if \fBfile\fR and \fBname\fR are set
605 but not \fBvalue\fR then the preference is deleted.
608 Lists recently played tracks.
611 Presents search results.
614 Primitive volume control.
616 Additionally, other standard files are included by these:
619 Included at the end of the main content \fB<DIV>\fR element.
622 Included at the start of the \fB<BODY>\fR element. (This supplants
623 \fBsidebar.html\fR, though the latter is still available; override label
624 \fBmenu\fR to choose between them.)
627 Included in the \fB<HEAD>\fR element.
630 Contains the default DisOrder stylesheet. You can override this by editing the
631 CSS or by replacing it all with a \fB<LINK>\fR to an external stylesheet.
633 Templates are ASCII files containing HTML documents, with an expansion
634 syntax to enable data supplied by the implementation to be inserted.
636 If you want to use characters outside the ASCII range, use either the
637 appropriate HTML entity, e.g. \fBé\fR, or an SGML numeric
638 character reference, e.g. \fBý\fR. Use \fB@\fR to insert a
639 literal \fB@\fR without falling foul of the expansion syntax.
640 .SS "Expansion Syntax"
641 Expansions are surrounded by at ("@") symbols take the form of a keyword
642 followed by zero or more arguments. Arguments may either be quoted by curly
643 brackets ("{" and "}") or separated by colons (":"). Both kinds may be mixed
644 in a single expansion, though doing so seems likely to cause confusion.
645 The descriptions below contain suggested forms for each
648 Leading and trailing whitespace in unquoted arguments is ignored, as is
649 whitespace (including newlines) following a close bracket ("}").
651 Arguments are recursively expanded before being interpreted, except for
652 \fITEMPLATE\fR arguments. These are expanded (possibly more than once) to
653 produce the final expansion.
654 (More than once means the same argument being expanded more than once
655 for different tracks or whatever, not the result of the first
656 expansion itself being re-expanded.)
658 Strings constructed by expansions (i.e. not literally copied from the template
659 text) are SGML-quoted: any character which does not stand for itself in #PCDATA
660 or a quoted attribute value is replaced by the appropriate numeric character
663 The exception to this is that such strings are \fInot\fR quoted when they are
664 generated in the expansion of a parameter.
666 In the descriptions below, the current track means the one set by
667 \fB@playing@\fR, \fB@recent@\fR or \fB@queue@\fR, not the one that is playing.
668 If none of these expansions are in force then there is no current track.
669 \fIBOOL\fR should always be either \fBtrue\fR or \fBfalse\fR.
671 The following expansion keywords are defined:
673 .B @#{\fICOMMENT\fB}@
677 The current action. This reports
679 if the action is really
685 .B @and{\fIBOOL\fB}{\fIBOOL\fB}\fR...\fB@
686 If there are no arguments, or all the arguments are \fBtrue\fB, then expands to
687 \fBtrue\fR, otherwise to \fBfalse\fR.
690 Expands to the value of CGI script argument \fINAME\fR.
693 The basename of the current directory component, in \fB@navigate@\fR.
695 .B @basename{\fIPATH\fB}@
696 The base name part of \fIPATH\fR.
698 .B @choose{\fIWHAT\fB}{\fITEMPLATE\fB}@
699 Expands \fITEMPLATE\fR repeatedly for each file or directory under
700 \fB@arg:directory@\fR.
701 \fIWHAT\fR should be either \fBfile\fR or \fBdirectory\fR.
702 Use \fB@file@\fR to get the display name or filename of the file or
704 Usually used in \fBchoose.html\fR.
707 The directory of the current directory component, in \fB@navigate@\fR.
709 .B @dirname{\fIPATH\fB}@
710 The directory part of \fIPATH\fR.
713 Expands to \fBtrue\fR if play is currently enabled, otherwise to \fBfalse\fR.
715 .B @eq{\fIA\fB}{\fIB\fB}
716 Expands to \fBtrue\fR if \fIA\fR and \fIB\fR are identical, otherwise to

810 If at least one argument is \fBtrue\fB, then expands to \fBtrue\fR, otherwise
814 Expands to \fBeven\fR or \fBodd\fR depending on whether the current track is at
815 an even or odd position in \fB@queue@\fR, \fB@recent@\fR or \fB@files@\fR.
817 .B @part{\fICONTEXT\fB}{\fIPART\fB}@
818 Expands to track name part \fIPART\fR using context \fICONTEXT\fR for the
819 current track. The context may be omitted and defaults
822 The special context \fBshort\fR is equivalent to \fBdisplay\fR but limited to
823 the \fBshort_display\fR limit.
825 .B @part{\fICONTEXT\fB}{\fIPART\fB}{\fITRACK\fB}@
826 Expands to track name part \fIPART\fR using context \fICONTEXT\fR for

862 .B @recent{\fITEMPLATE\fB}@
863 Expands \fITEMPLATE\fR repeatedly using the each recently played track in turn

872 The groups are sorted by the value of the part.
877 within the template will apply to one of the tracks in the group.
879 If \fICONTEXT\fR is specified it should be either \fBsort\fR or \fBdisplay\fR,
880 and determines the context for \fIPART\fR. The default is \fBsort\fR. Usually
881 you want \fBdisplay\fR for everything except the title and \fBsort\fR for the
882 title. If you use \fBsort\fR for artist and album then you are likely to get
886 Expands to the server's version string.
888 .B @shell{\fICOMMAND\fB}@
889 Expands to the output of \fICOMMAND\fR executed via the shell. \fBsh\fR is
890 searched for using \fBPATH\fR. If the command fails then this is logged but
894 In \fB@queue@\fR and \fB@recent@\fR, expands to the state of the current
895 track. Otherwise the empty string. Known states are:
899 The player terminated with nonzero status, but not because the track was
903 A scratch, in the queue.
906 No player could be found.
912 A randomly chosen track, in the queue.
915 This track was scratched.
918 An explicitly queued track, in the queue.
921 Some additional states only apply to playing tracks, so will never be seen in
922 the queue or recently-played list:
926 The track has been paused.
929 Interrupted because the server is shutting down.
932 This track is currently playing.
936 Expands to the server statistics.
939 Expands to the URL of the current page. Typically used in

950 playing now, \fBqueued\fR if it is queued or the empty string otherwise.
952 .B @transform{\fIPATH\fB}{\fITYPE\fB}{\fICONTEXT\fB}@
953 Transform a path according to \fBtransform\fR (see above).

974 has not been played yet)
977 Who submitted the current track.
979 This is a file called \fIoptions\fR, searched for in the same manner
980 as templates. It includes numerous options for the control of the web
981 interface. The general syntax is the same as the main configuration
982 file, except that it should be encoded using UTF-8 (though this might
983 change to the current locale's character encoding; stick to ASCII to
986 The shipped \fIoptions\fR file includes four standard options files.
990 The default labels file. You wouldn't normally edit this directly - instead
991 supply your own commands in \fIoptions.user\fR. Have a look at the shipped
992 version of the file for documentation of labels used by the standard templates.
995 A user options file. Here you should put any overrides for the default
996 labels and any extra labels required by your modified templates.
998 Valid directives are:
1000 .B columns \fINAME\fR \fIHEADING\fR...
1001 Defines the columns used in \fB@playing@\fR and \fB@recent@\fB. \fINAME\fR
1002 must be either \fBplaying\fR, \fBrecent\fR or \fBsearch\fR.
1003 \fIHEADING\fR... is a list of
1004 heading names. If a column is defined more than once then the last definitions
1007 The heading names \fBbutton\fR, \fBlength\fR, \fBwhen\fR and \fBwho\fR
1010 .B include \fIPATH\fR
1011 Includes another file. If \fIPATH\fR starts with a \fB/\fR then it is
1012 taken as is, otherwise it is searched for in the template path.
1014 .B label \fINAME\fR \fIVALUE\fR
1015 Define a label. If a label is defined more than once then the last definition
1018 Some labels are defined inside \fBdisorder.cgi\fR and others by the
1019 default templates. You can define your own labels and use them inside
1022 When an undefined label is expanded, if it has a dot in its name then
1023 the part after the final dot is used as its value. Otherwise the
1024 whole name is used as the value.
1026 Labels are no longer documented here, see the shipped \fIoptions.labels\fR file
1028 .SH "REGEXP SUBSTITUTION RULES"
1029 Regexps are PCRE regexps, as defined in \fBpcrepattern\fR(3). The
1030 only option used is \fBPCRE_UTF8\fR. Remember that the configuration
1031 file syntax means you have to escape backslashes and quotes inside
1034 In a \fISUBST\fR string the following sequences are interpreted
1038 These expand to the first to ninth bracketed subexpression.
1041 This expands to the matched part of the subject string.
1044 This expands to a single \fB$\fR symbol.
1046 All other pairs starting with \fB$\fR are undefined (and might be used
1047 for something else in the future, so don't rely on the current
1050 If \fBi\fR is present in \fIREFLAGS\fR then the match is case-independent. If
1051 \fBg\fR is present then all matches are replaced, otherwise only the first
1054 What the web interface actually does is terminated by the \fBaction\fR CGI
1055 argument. The values listed below are supported.
1057 Except as specified, all actions redirect back to the \fBplaying.html\fR
1058 template unless the \fBback\fR argument is present, in which case the URL it
1059 gives is used instead.
1061 Redirection to \fBplaying.html\fR preserves \fBmgmt=true\fR if it is present.
1064 Move track \fBid\fR by offset \fBdelta\fR.
1067 Play track \fBfile\fR, or if that is missing then play all the tracks in
1071 Don't change any state, but instead compute a suitable refresh time and include
1072 that in an HTTP header. Expands the \fBplaying.html\fR template rather than
1075 This is the default if \fBaction\fR is missing.
1078 Disables random play.
1081 Enables random play.
1084 Disables play completely.
1090 Pauses the current track.
1093 Remove track \fBid\fR.
1096 Resumes play after a pause.
1099 Scratch the playing track. If \fBid\fR is present it must match the playing
1103 Change the volume by \fBdelta\fR, or if that is missing then set it to the
1104 values of \fBleft\fR and \fBright\fR. Expands to the \fBvolume.html\fR template
1105 rather than redirecting.
1108 Adjust preferences from the \fBprefs.html\fR template (which it then expands
1109 rather than redirecting).
1113 is set then the cooked interface is assumed. The value of
1115 is used to determine which trackname preferences are set. By default the
1117 context is adjusted but this can be overridden with the
1121 argument is checked; if it is set then random play is enabled for that track,
1122 otherwise it is disabled.
1128 arguments are set then they are used to set a single preference.
1130 Otherwise if just the
1132 argument is set then that preference is deleted.
1134 It is recommended that links to the \fBprefs\fR action use \fB@resolve@\fR to
1135 enure that the real track name is always used. Otherwise if the preferences
1136 page is used to adjust a trackname_ preference, the alias may change, leading
1137 to the URL going stale.
1140 This action is generated automatically when an error occurs connecting to the
1141 server. The \fBerror\fR label is set to an indication of what the error is.
1142 .SH "TRACK NAME PARTS"
1143 The traditional track name parts are \fBartist\fR, \fBalbum\fR and \fBtitle\fR,
1144 with the obvious intended meaning. These are controlled by configuration and
1145 by \fBtrackname_\fR preferences.
1147 In addition there are two built-in parts, \fBpath\fR which is the whole path
1148 name and \fBext\fR which is the filename extension, including the initial dot
1149 (or the empty string if there is not extension).
