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 channel \fICHANNEL\fR
146 The mixer channel that the volume control should use. Valid names depend on
147 your operating system and hardware, but some standard ones that might be useful
152 Output level for the audio device. This is probably what you want.
155 Output level for the PC speaker, if that is connected to the sound card.
158 Output level for alternative codec device.
161 Master output level. The OSS documentation recommends against using this, as
162 it affects all output devices.
165 You can also specify channels by number, if you know the right value.
167 .B collection \fIMODULE\fR \fIENCODING\fR \fIROOT\fR
168 Define a collection of tracks.
170 \fIMODULE\fR defines which plugin module should be used for this
171 collection. Use the supplied \fBfs\fR module for tracks that exists
172 as ordinary files in the filesystem.
174 \fIENCODING\fR defines the encoding of filenames in this collection.
175 For \fBfs\fR this would be the encoding you use for filenames.
176 Examples might be \fBiso-8859-1\fR or \fButf-8\fR.
178 \fIROOT\fR is the root in the filesystem of the filenames and is
179 passed to the plugin module.
182 ALSA device to play raw-format audio. Default is \fBdefault\fR, i.e. to use
183 the whatever the ALSA configured default is.
186 Specifies the number of seconds to leave between tracks. The default
189 .B history \fIINTEGER\fR
190 Specifies the number of recently played tracks to remember (including
191 failed tracks and scratches).
193 .B listen \fR[\fIHOST\fR] \fISERVICE\fR
194 Listen for connections on the address specified by \fIHOST\fR and port
195 specified by \fISERVICE\fR. If \fIHOST\fR is omitted then listens on all
198 Normally the server only listens on a UNIX domain socket.
201 Determines whether the server locks against concurrent operation. Default is
205 The path to the mixer device, if you want access to the volume control,
206 e.g. \fB/dev/mixer\fR.
208 .B namepart \fIPART\fR \fIREGEXP\fR \fISUBST\fR [\fICONTEXT\fR [\fIREFLAGS\fR]]
209 Determines how to extract trackname part \fIPART\fR from a
210 track name (with the collection root part removed).
211 Used in \fB@recent@\fR, \fB@playing@\fR and \fB@search@\fR.
213 Track names can be different in different contexts. For instance the sort
214 string might include an initial track number, but this would be stripped for
215 the display string. \fICONTEXT\fR should be a glob pattern matching the
216 contexts in which this directive will be used.
218 Valid contexts are \fBsort\fR and \fBdisplay\fR.
220 All the \fBnamepart\fR directives are considered in order. The
221 first directive for the right part, that matches the desired context,
222 and with a \fIREGEXP\fR that
223 matches the track is used, and the value chosen is constructed from
224 \fISUBST\fR according to the substitution rules below.
226 Note that searches use the raw track name and \fBtrackname_\fR preferences but
227 not (currently) the results of \fBnamepart\fR, so generating words via this option
228 that aren't in the original track name will lead to confusing results.
230 If you supply no \fBnamepart\fR directives at all then a default set will be
231 supplied automatically. But if you supply even one then you must supply all of
232 them. See the example config file for the defaults.
234 .B nice_rescan \fIPRIORITY\fR
235 Set the recan subprocess priority. The default is 10.
237 (Note that higher values mean the process gets less CPU time; UNIX priority
238 values are the backwards.)
240 .B nice_server \fIPRIORITY\fR
241 Set the server priority. This is applied to the server at startup time (and
242 not when you reload configuration). The server does not use much CPU itself
243 but this value is inherited by programs it executes. If you have limited CPU
244 then it might help to set this to a small negative value. The default is 0.
246 .B nice_speaker \fIPRIORITY\fR
247 Set the speaker process priority. This is applied to the speaker process at
248 startup time (and not when you reload the configuration). The speaker process
249 is not massively CPU intensive by today's standards but depends on reasonably
250 timely scheduling. If you have limited CPU then it might help to set this to a
251 small negative value. The default is 0.
253 .B player \fIPATTERN\fR \fIMODULE\fR [\fIOPTIONS.. [\fB--\fR]] \fIARGS\fR...
254 Specifies the player for files matching the glob \fIPATTERN\fR. \fIMODULE\fR
255 specifies which plugin module to use.
257 The following options are supported:
260 .B --wait-for-device\fR[\fB=\fIDEVICE\fR]
261 Waits (for up to a couple of seconds) for the default, or specified, libao
262 device to become openable.
265 Defines the end of the list of options. Needed if the first argument to the
266 plugin starts with a "-".
269 The following are the standard modules:
272 .B exec \fICOMMAND\fR \fIARGS\fR...
273 The command is executed via \fBexecvp\fR(3), not via the shell.
274 The \fBPATH\fR environment variable is searched for the executable if it is not
276 The command is expected to know how to open its own sound device.
278 .B execraw \fICOMMAND\fR \fIARGS\fR...
279 Identical to the \fBexec\fR except that the player is expected to use the
280 DisOrder raw player protocol (see notes below).
282 .B shell \fR[\fISHELL\fR] \fICOMMAND\fR
283 The command is executed using the shell. If \fISHELL\fR is specified then that
284 is used, otherwise \fBsh\fR will be used. In either case the \fBPATH\fR
285 environment variable is searched for the shell executable if it is not an
286 absolute path. The track name is stored in the environment variable
289 Be careful of the interaction between the configuration file quoting rules and
290 the shell quoting rules.
293 If multiple player commands match a track then the first match is used.
295 .B prefsync \fISECONDS\fR
296 The interval at which the preferences log file will be synchronised. Defaults
297 to 3600, i.e. one hour.
299 .B sample_format \fIBITS\fB/\fIRATE\fB/\fICHANNELS
300 Describes the sample format expected by the \fBspeaker_command\fR (below). The
301 components of the format specification are as follows:
305 The number of bits per sample. Optionally, may be suffixed by \fBb\fR or
306 \fBl\fR for big-endian and little-endian words. If neither is used the native
307 byte order is assumed.
310 The number of samples per second.
313 The number of channels.
320 Defines the signal to be sent to track player process groups when tracks are
321 scratched. The default is \fBSIGKILL\fR.
323 Signals are specified by their full C name, i.e. \fBSIGINT\fR and not \fBINT\fR
324 or \fBInterrupted\fR or whatever.
326 .B sox_generation \fB0\fR|\fB1
327 Determines whether calls to \fBsox\fR(1) should use \fB-b\fR, \fB-x\fR, etc (if
328 the generation is 0) or \fB-\fIbits\fR, \fB-L\fR etc (if it is 1). The default
331 .B speaker_command \fICOMMAND
332 Causes the speaker subprocess to pipe audio data into shell command
333 \fICOMMAND\fR, rather than writing to a local sound card. The sample format is
338 Note that if the sample format is wrong then
340 is invoked to translate it. If
342 is not installed then this will not work.
344 .B restrict \fR[\fBscratch\fR] [\fBremove\fR] [\fBmove\fR]
345 Determine which operations are restricted to the submitter of a
346 track. By default, no operations are restricted, i.e. anyone can
347 scratch or remove anything.
349 If \fBrestrict scratch\fR or \fBrestrict remove\fR are set then only the user
350 that submitted a track can scratch or remove it, respectively.
352 If \fBrestrict move\fR is set then only trusted users can move tracks around in
355 If \fBrestrict\fR is used more than once then only the final use has any
358 .B scratch \fIPATH\fR
359 Specifies a scratch. When a track is scratched, a scratch track is
361 Scratches are played using the same logic as other tracks.
363 At least for the time being, path names of scratches must be encoded using
364 UTF-8 (which means that ASCII will do).
366 .B stopword \fIWORD\fR ...
367 Specifies one or more stopwords that should not take part in searches
369 .SS "Client Configuration"
371 .B connect \fR[\fIHOST\fR] \fISERVICE\fR
372 Connect to the address specified by \fIHOST\fR and port specified by
373 \fISERVICE\fR. If \fIHOST\fR is omitted then connects to the local host.
374 Normally the UNIX domain socket is used instead.
375 .SS "Web Interface Configuration"
377 .B refresh \fISECONDS\fR
378 Specifies the maximum refresh period in seconds. Default 15.
380 .B templates \fIPATH\fR ...
381 Specifies the directory containing templates used by the web
382 interface. If a template appears in more than one template directory
383 then the one in the earliest directory specified is chosen.
385 See below for further details.
387 .B transform \fITYPE\fR \fIREGEXP\fR \fISUBST\fR [\fICONTEXT\fR [\fIREFLAGS\fR]]
388 Determines how names are sorted and displayed in track choice displays.
390 \fITYPE\fR is the type of transformation; usually \fBtrack\fR or
391 \fBdir\fR but you can define your own.
393 \fICONTEXT\fR is a glob pattern matching the context. Standard contexts are
394 \fBsort\fR (which determines how directory names are sorted) and \fBdisplay\fR
395 (which determines how they are displayed). Again, you can define your
398 All the \fBtransform\fR directives are considered in order. If
399 the \fITYPE\fR, \fIREGEXP\fR and the \fICONTEXT\fR match
400 then a new track name is constructed from
401 \fISUBST\fR according to the substitution rules below. If several
402 match then each is executed in order.
404 If you supply no \fBtransform\fR directives at all then a default set will be
405 supplied automatically. But if you supply even one then you must supply all of
406 them. See the example config file for the defaults.
409 Specifies the URL of the web interface. This URL will be used in
412 This must be the full URL, e.g. \fBhttp://myhost/cgi-bin/jukebox\fR and not
413 \fB/cgi-bin/jukebox\fR.
414 .SS "Authentication Configuration"
416 .B allow \fIUSERNAME\fR \fIPASSWORD\fR
417 Specify a username/password pair.
419 .B password \fIPASSWORD\fR
422 .B trust \fIUSERNAME\fR
423 Allow \fIUSERNAME\fR to perform privileged operations such as shutting
424 down or reconfiguring the daemon, or becoming another user.
427 Specifies the user to run as. Only makes sense if invoked as root (or
430 .B username \fIUSERNAME\fR
431 Specify username. The default is taken from the environment variable
434 Configuration files are read in the following order:
438 .I pkgconfdir/config.private
439 Should be readable only by the jukebox group, and contain \fBallow\fR
440 commands for authorised users.
442 .I pkgconfdir/config.\fRUSER
443 Per-user system-controlled client configuration. Optional but if it
444 exists must be readable only by the relevant user. Would normally
445 contain a \fBpassword\fR directive.
447 .I ~\fRUSER\fI/.disorder/passwd
448 Per-user client configuration. Optional but if it exists must be
449 readable only by the relevant user. Would normally contain a
450 \fBpassword\fR directive.
451 .SH "GLOBAL PREFERENCES"
452 These are the values set with \fBset-global\fR.
455 If this is set an nonempty then randomly played tracks will always have at
456 least one of the listed tags.
458 Tags can contain any printing character except comma. Leading and trailing
459 spaces are not significant but internal spaces are. Tags in a list are
463 If this is set an nonempty then randomly played tracks will never have any of
467 If unset or \fByes\fR then play is enabled. Otherwise it is disabled. Use
468 \fBdisable\fR rather than setting it directly.
471 If unset or \fByes\fR then random play is enabled. Otherwise it is disabled.
472 Use \fBdisable\fR rather than setting it directly.
474 .SS "Raw Protocol Players"
475 Raw protocol players are expected to use the \fBdisorder\fR libao driver.
476 Programs that use libao generally have command line options to select the
477 driver and pass options to it.
479 The known driver options are:
482 The file descriptor to write to. If this is not specified then the driver
483 looks like the environment variable \fBDISORDER_RAW_FD\fR. If that is not set
484 then the default is 1 (i.e. standard output).
487 If this is set to a nonzero value then the driver will call \fB_exit\fR(2) if a
488 write to the output file descriptor fails. This is a workaround for buggy
489 players such as \fBogg123\fR that ignore write errors.
491 When \fBdisorder.cgi\fR wants to generate a page for an action it searches the
492 directories specified with \fBtemplates\fR for a matching file. It is
493 suggested that you leave the distributed templates unchanged and put
494 any customisations in an earlier entry in the template path.
496 The supplied templates are:
499 Display information about DisOrder.
502 Navigates through the track database to choose a track to play. The
503 \fBdir\fR argument gives the directory to look in; if it is missing
504 then the root directory is used.
507 Provides a front end to \fBchoose.html\fR which allows subsets of the top level
508 directories to be selected by initial letter.
511 The "front page", which usually shows the currently playing tracks and
513 Gets an HTTP \fBRefresh\fR header.
515 If the \fBmgmt\fR CGI argument is set to \fBtrue\fR then we include extra
516 buttons for moving tracks up and down in the queue. There is some logic in
517 \fBdisorder.cgi\fR to ensure that \fBmgmt=true\fR is preserved across refreshes
518 and redirects back into itself, but URLs embedded in web pages must include it
522 Views preferences. If the \fBfile\fR, \fBname\fR and \fBvalue\fR arguments are
523 all set then that preference is modified; if \fBfile\fR and \fBname\fR are set
524 but not \fBvalue\fR then the preference is deleted.
527 Lists recently played tracks.
530 Presents search results.
533 Primitive volume control.
535 Additionally, other standard files are included by these:
538 Included at the end of the main content \fB<DIV>\fR element.
541 Included at the start of the \fB<BODY>\fR element.
544 Included in the \fB<HEAD>\fR element.
547 Contains the default DisOrder stylesheet. You can override this by editing the
548 CSS or by replacing it all with a \fB<LINK>\fR to an external stylesheet.
550 Templates are ASCII files containing HTML documents, with an expansion
551 syntax to enable data supplied by the implementation to be inserted.
553 If you want to use characters outside the ASCII range, use either the
554 appropriate HTML entity, e.g. \fBé\fR, or an SGML numeric
555 character reference, e.g. \fBý\fR. Use \fB@\fR to insert a
556 literal \fB@\fR without falling foul of the expansion syntax.
557 .SS "Expansion Syntax"
558 Expansions are surrounded by at ("@") symbols take the form of a keyword
559 followed by zero or more arguments. Arguments may either be quoted by curly
560 brackets ("{" and "}") or separated by colons (":"). Both kinds may be mixed
561 in a single expansion, though doing so seems likely to cause confusion.
562 The descriptions below contain suggested forms for each
565 Leading and trailing whitespace in unquoted arguments is ignored, as is
566 whitespace (including newlines) following a close bracket ("}").
568 Arguments are recursively expanded before being interpreted, except for
569 \fITEMPLATE\fR arguments. These are expanded (possibly more than once) to
570 produce the final expansion.
571 (More than once means the same argument being expanded more than once
572 for different tracks or whatever, not the result of the first
573 expansion itself being re-expanded.)
575 Strings constructed by expansions (i.e. not literally copied from the template
576 text) are SGML-quoted: any character which does not stand for itself in #PCDATA
577 or a quoted attribute value is replaced by the appropriate numeric character
580 The exception to this is that such strings are \fInot\fR quoted when they are
581 generated in the expansion of a parameter.
583 In the descriptions below, the current track means the one set by
584 \fB@playing@\fR, \fB@recent@\fR or \fB@queue@\fR, not the one that is playing.
585 If none of these expansions are in force then there is no current track.
586 \fIBOOL\fR should always be either \fBtrue\fR or \fBfalse\fR.
588 The following expansion keywords are defined:
590 .B @#{\fICOMMENT\fB}@
594 The current action. This reports
596 if the action is really
602 .B @and{\fIBOOL\fB}{\fIBOOL\fB}\fR...\fB@
603 If there are no arguments, or all the arguments are \fBtrue\fB, then expands to
604 \fBtrue\fR, otherwise to \fBfalse\fR.
607 Expands to the value of CGI script argument \fINAME\fR.
610 The basename of the current directory component, in \fB@navigate@\fR.
612 .B @basename{\fIPATH\fB}@
613 The base name part of \fIPATH\fR.
615 .B @choose{\fIWHAT\fB}{\fITEMPLATE\fB}@
616 Expands \fITEMPLATE\fR repeatedly for each file or directory under
617 \fB@arg:directory@\fR.
618 \fIWHAT\fR should be either \fBfile\fR or \fBdirectory\fR.
619 Use \fB@file@\fR to get the display name or filename of the file or
621 Usually used in \fBchoose.html\fR.
624 The directory of the current directory component, in \fB@navigate@\fR.
626 .B @dirname{\fIPATH\fB}@
627 The directory part of \fIPATH\fR.
630 Expands to \fBtrue\fR if play is currently enabled, otherwise to \fBfalse\fR.
632 .B @eq{\fIA\fB}{\fIB\fB}
633 Expands to \fBtrue\fR if \fIA\fR and \fIB\fR are identical, otherwise to
637 Expands to the filename of the current file or directory, inside the template
638 argument to \fBchoose\fR.
640 .B @files{\fITEMPLATE\fB}
641 Expands \fITEMPLATE\fB once for each file indicated by the \fBdirectory\fR CGI
642 arg if it is present, or otherwise for the list of files counted by \fBfiles\fR
643 with names \fB0_file\fR, \fB1_file\fR etc.
646 The full path of the current directory component, in \fB@navigate@\fR.
649 The ID of the current track.
651 .B @if{\fIBOOL\fB}{\fITRUEPART\fB}{\fIFALSEPART\fB}@
652 If \fIBOOL\fR expands to \fBtrue\fR then expands to \fITRUEPART\fR, otherwise
653 to \fIFALSEPART\fR (which may be omitted).
655 .B @include:\fIPATH\fR@
656 Include the named file as if it were a template file. If \fIPATH\fR
657 starts with a \fB/\fR then it is used as-is; otherwise, ".html" is
658 appended and the template path is searched.
661 Expands to the index of the current file in \fB@queue@\fR, \fB@recent@\fR or
665 Expands to \fBtrue\fR if there are any directories in \fB@arg:directory@\fR,
666 otherwise to \fBfalse\fR.
669 Expands to \fBtrue\fR if there are any files in \fB@arg:directory@\fR,
670 otherwise to \fBfalse\fR.
673 Expands to \fBtrue\fR if this is the first repetition of a \fITEMPLATE\fR
674 argument in a loop (\fB@queue\fR or similar), otherwise to \fBfalse\fR.
677 Expands to \fBtrue\fR if this is the last repetition of a \fITEMPLATE\fR in a
678 loop, otherwise to \fBfalse\fR.
681 Expands to \fBtrue\fR if a track is playing, otherwise to \fBfalse\fR.
684 Expands to \fBtrue\fR if there are any tracks in the queue, otherwise to
688 Expands to \fBtrue\fR if the recently played list has any tracks in it,
689 otherwise to \fBfalse\fR.
691 .B @label:\fINAME\fR\fB@
692 Expands to the value of label \fINAME\fR. See the shipped \fIoptions.labels\fR
693 file for full documentation of the labels used by the standard templates.
696 Expands to the length of the current track.
698 .B @navigate{\fIDIRECTORY\fB}{\fITEMPLATE\fB}
699 Expands \fITEMPLATE\fR for each component of \fIDIRECTORY\fR in turn.
700 Use \fB@dirname\fR and \fB@basename@\fR to get the components of the path to
702 Usually used in \fBchoose.html\fR.
704 .B @ne{\fIA\fB}{\fIB\fB}
705 Expands to \fBtrue\fR if \fIA\fR and \fIB\fR differ, otherwise to \fBfalse\fR.
708 Expands to the number of files from \fB@files\fR (above).
711 Expands to a string including the time and process ID, intended to be
712 unique across invocations.
715 Expands to \fBfalse\fR if \fIBOOL\fR is \fBtrue\fR, otherwise to
718 .B @or{\fIBOOL\fB}{\fIBOOL\fB}\fR...\fB@
719 If at least one argument is \fBtrue\fB, then expands to \fBtrue\fR, otherwise
723 Expands to \fBeven\fR or \fBodd\fR depending on whether the current track is at
724 an even or odd position in \fB@queue@\fR, \fB@recent@\fR or \fB@files@\fR.
726 .B @part{\fICONTEXT\fB}{\fIPART\fB}@
727 Expands to track name part \fIPART\fR using context \fICONTEXT\fR for the
728 current track. The context may be omitted (and normally would be) and defaults
731 .B @part{\fICONTEXT\fB}{\fIPART\fB}{\fITRACK\fB}@
732 Expands to track name part \fIPART\fR using context \fICONTEXT\fR for
733 \fITRACK\fR. In this usage the context may not be omitted.
736 Expands to \fBtrue\fR if the current track is paused, else \fBfalse\fR.
738 .B @playing{\fITEMPLATE\fB}@
739 Expands \fITEMPLATE\fR using the playing track as the current track.
741 .B @pref{\fITRACK\fB}{\fIKEY\fB}@
742 Expand to the track preference, or the empty string if it is not set.
745 Expands to the name of the current preference, in the template
746 argument of \fB@prefs@\fR.
748 .B @prefs{\fIFILE\fB}{\fITEMPLATE\fB}@
749 Expands \fITEMPLATE\fR repeatedly, for each preference of track
751 Use \fB@prefname@\fR and \fB@prefvalue@\fR to get the name and value.
754 Expands to the value of the current preference, in the template
755 argument of \fB@prefs@\fR.
757 .B @queue{\fITEMPLATE\fB}@
758 Expands \fITEMPLATE\fR repeatedly using the each track on the queue in turn as
759 the current track. The track at the head of the queue comes first.
762 Expands to \fBtrue\fR if random play is currently enabled, otherwise to
765 .B @recent{\fITEMPLATE\fB}@
766 Expands \fITEMPLATE\fR repeatedly using the each recently played track in turn
767 as the current track. The most recently played track comes first.
769 .B @resolve{\fITRACK\fB}@
770 Resolve aliases for \fITRACK\fR and expands to the result.
772 .B @search{\fIPART\fB}\fR[\fB{\fICONTEXT\fB}\fR]\fB{\fITEMPLATE\fB}@
773 Expands \fITEMPLATE\fR once for each group of search results that have
774 a common value of track part \fIPART\fR.
775 The groups are sorted by the value of the part.
780 within the template will apply to one of the tracks in the group.
782 If \fICONTEXT\fR is specified it should be either \fBsort\fR or \fBdisplay\fR,
783 and determines the context for \fIPART\fR. The default is \fBsort\fR. Usually
784 you want \fBdisplay\fR for everything except the title and \fBsort\fR for the
785 title. If you use \fBsort\fR for artist and album then you are likely to get
789 Expands to the server's version string.
791 .B @shell{\fICOMMAND\fB}@
792 Expands to the output of \fICOMMAND\fR executed via the shell. \fBsh\fR is
793 searched for using \fBPATH\fR. If the command fails then this is logged but
797 In \fB@queue@\fR and \fB@recent@\fR, expands to the state of the current
798 track. Otherwise the empty string. Known states are:
802 The player terminated with nonzero status, but not because the track was
806 A scratch, in the queue.
809 No player could be found.
815 A randomly chosen track, in the queue.
818 This track was scratched.
821 An explicitly queued track, in the queue.
824 Some additional states only apply to playing tracks, so will never be seen in
825 the queue or recently-played list:
829 The track has been paused.
832 Interrupted because the server is shutting down.
835 This track is currently playing.
839 Expands to the server statistics.
842 Expands to the URL of the current page. Typically used in
844 arguments. If there is a
846 argument then it is changed to a fresh value.
851 .B @trackstate{\fIPATH\fB}@
852 Expands to the current track state: \fBplaying\fR if the track is actually
853 playing now, \fBqueued\fR if it is queued or the empty string otherwise.
855 .B @transform{\fIPATH\fB}{\fITYPE\fB}{\fICONTEXT\fB}@
856 Transform a path according to \fBtransform\fR (see above).
857 \fIPATH\fR should be a raw filename (of a track or directory).
858 \fITYPE\fR should be the transform type (e.g. \fItrack\fR or \fIdir\fR).
859 \fICONTEXT\fR should be the context, and can be omitted (the default
863 Expands to the canonical URL as defined in \fIpkgconfdir/config\fR.
865 .B @urlquote{\fISTRING\fB}@
866 URL-quote \fISTRING\fR.
869 Expands to \fBdisorder.cgi\fR's version string.
871 .B @volume:\fISPEAKER\fB@
872 The volume on the left or right speaker. \fISPEAKER\fR must be \fBleft\fB or
876 When the current track was played (or when it is expected to be played, if it
877 has not been played yet)
880 Who submitted the current track.
882 This is a file called \fIoptions\fR, searched for in the same manner
883 as templates. It includes numerous options for the control of the web
884 interface. The general syntax is the same as the main configuration
885 file, except that it should be encoded using UTF-8 (though this might
886 change to the current locale's character encoding; stick to ASCII to
889 The shipped \fIoptions\fR file includes four standard options files.
893 The default labels file. You wouldn't normally edit this directly - instead
894 supply your own commands in \fIoptions.user\fR. Have a look at the shipped
895 version of the file for documentation of labels used by the standard templates.
898 A user options file. Here you should put any overrides for the default
899 labels and any extra labels required by your modified templates.
901 Valid directives are:
903 .B columns \fINAME\fR \fIHEADING\fR...
904 Defines the columns used in \fB@playing@\fR and \fB@recent@\fB. \fINAME\fR
905 must be either \fBplaying\fR, \fBrecent\fR or \fBsearch\fR.
906 \fIHEADING\fR... is a list of
907 heading names. If a column is defined more than once then the last definitions
910 The heading names \fBbutton\fR, \fBlength\fR, \fBwhen\fR and \fBwho\fR
913 .B include \fIPATH\fR
914 Includes another file. If \fIPATH\fR starts with a \fB/\fR then it is
915 taken as is, otherwise it is searched for in the template path.
917 .B label \fINAME\fR \fIVALUE\fR
918 Define a label. If a label is defined more than once then the last definition
921 Some labels are defined inside \fBdisorder.cgi\fR and others by the
922 default templates. You can define your own labels and use them inside
925 When an undefined label is expanded, if it has a dot in its name then
926 the part after the final dot is used as its value. Otherwise the
927 whole name is used as the value.
929 Labels are no longer documented here, see the shipped \fIoptions.labels\fR file
931 .SH "REGEXP SUBSTITUTION RULES"
932 Regexps are PCRE regexps, as defined in \fBpcrepattern\fR(3). The
933 only option used is \fBPCRE_UTF8\fR. Remember that the configuration
934 file syntax means you have to escape backslashes and quotes inside
937 In a \fISUBST\fR string the following sequences are interpreted
941 These expand to the first to ninth bracketed subexpression.
944 This expands to the matched part of the subject string.
947 This expands to a single \fB$\fR symbol.
949 All other pairs starting with \fB$\fR are undefined (and might be used
950 for something else in the future, so don't rely on the current
953 If \fBi\fR is present in \fIREFLAGS\fR then the match is case-independent. If
954 \fBg\fR is present then all matches are replaced, otherwise only the first
957 What the web interface actually does is terminated by the \fBaction\fR CGI
958 argument. The values listed below are supported.
960 Except as specified, all actions redirect back to the \fBplaying.html\fR
961 template unless the \fBback\fR argument is present, in which case the URL it
962 gives is used instead.
964 Redirection to \fBplaying.html\fR preserves \fBmgmt=true\fR if it is present.
967 Move track \fBid\fR by offset \fBdelta\fR.
970 Play track \fBfile\fR, or if that is missing then play all the tracks in
974 Don't change any state, but instead compute a suitable refresh time and include
975 that in an HTTP header. Expands the \fBplaying.html\fR template rather than
978 This is the default if \fBaction\fR is missing.
981 Disables random play.
987 Disables play completely.
993 Pauses the current track.
996 Remove track \fBid\fR.
999 Resumes play after a pause.
1002 Scratch the playing track. If \fBid\fR is present it must match the playing
1006 Change the volume by \fBdelta\fR, or if that is missing then set it to the
1007 values of \fBleft\fR and \fBright\fR. Expands to the \fBvolume.html\fR template
1008 rather than redirecting.
1011 Adjust preferences from the \fBprefs.html\fR template (which it then expands
1012 rather than redirecting).
1016 is set then the cooked interface is assumed. The value of
1018 is used to determine which trackname preferences are set. By default the
1020 context is adjusted but this can be overridden with the
1024 argument is checked; if it is set then random play is enabled for that track,
1025 otherwise it is disabled.
1031 arguments are set then they are used to set a single preference.
1033 Otherwise if just the
1035 argument is set then that preference is deleted.
1037 It is recommended that links to the \fBprefs\fR action use \fB@resolve@\fR to
1038 enure that the real track name is always used. Otherwise if the preferences
1039 page is used to adjust a trackname_ preference, the alias may change, leading
1040 to the URL going stale.
1043 This action is generated automatically when an error occurs connecting to the
1044 server. The \fBerror\fR label is set to an indication of what the error is.
1045 .SH "TRACK NAME PARTS"
1046 The traditional track name parts are \fBartist\fR, \fBalbum\fR and \fBtitle\fR,
1047 with the obvious intended meaning. These are controlled by configuration and
1048 by \fBtrackname_\fR preferences.
1050 In addition there are two built-in parts, \fBpath\fR which is the whole path
1051 name and \fBext\fR which is the filename extension, including the initial dot
1052 (or the empty string if there is not extension).
