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.
300 Defines the signal to be sent to track player process groups when tracks are
301 scratched. The default is \fBSIGKILL\fR.
303 Signals are specified by their full C name, i.e. \fBSIGINT\fR and not \fBINT\fR
304 or \fBInterrupted\fR or whatever.
306 .B restrict \fR[\fBscratch\fR] [\fBremove\fR] [\fBmove\fR]
307 Determine which operations are restricted to the submitter of a
308 track. By default, no operations are restricted, i.e. anyone can
309 scratch or remove anything.
311 If \fBrestrict scratch\fR or \fBrestrict remove\fR are set then only the user
312 that submitted a track can scratch or remove it, respectively.
314 If \fBrestrict move\fR is set then only trusted users can move tracks around in
317 If \fBrestrict\fR is used more than once then only the final use has any
320 .B scratch \fIPATH\fR
321 Specifies a scratch. When a track is scratched, a scratch track is
323 Scratches are played using the same logic as other tracks.
325 At least for the time being, path names of scratches must be encoded using
326 UTF-8 (which means that ASCII will do).
328 .B stopword \fIWORD\fR ...
329 Specifies one or more stopwords that should not take part in searches
331 .SS "Client Configuration"
333 .B connect \fR[\fIHOST\fR] \fISERVICE\fR
334 Connect to the address specified by \fIHOST\fR and port specified by
335 \fISERVICE\fR. If \fIHOST\fR is omitted then connects to the local host.
336 Normally the UNIX domain socket is used instead.
337 .SS "Web Interface Configuration"
339 .B refresh \fISECONDS\fR
340 Specifies the maximum refresh period in seconds. Default 15.
342 .B templates \fIPATH\fR ...
343 Specifies the directory containing templates used by the web
344 interface. If a template appears in more than one template directory
345 then the one in the earliest directory specified is chosen.
347 See below for further details.
349 .B transform \fITYPE\fR \fIREGEXP\fR \fISUBST\fR [\fICONTEXT\fR [\fIREFLAGS\fR]]
350 Determines how names are sorted and displayed in track choice displays.
352 \fITYPE\fR is the type of transformation; usually \fBtrack\fR or
353 \fBdir\fR but you can define your own.
355 \fICONTEXT\fR is a glob pattern matching the context. Standard contexts are
356 \fBsort\fR (which determines how directory names are sorted) and \fBdisplay\fR
357 (which determines how they are displayed). Again, you can define your
360 All the \fBtransform\fR directives are considered in order. If
361 the \fITYPE\fR, \fIREGEXP\fR and the \fICONTEXT\fR match
362 then a new track name is constructed from
363 \fISUBST\fR according to the substitution rules below. If several
364 match then each is executed in order.
366 If you supply no \fBtransform\fR directives at all then a default set will be
367 supplied automatically. But if you supply even one then you must supply all of
368 them. See the example config file for the defaults.
371 Specifies the URL of the web interface. This URL will be used in
374 This must be the full URL, e.g. \fBhttp://myhost/cgi-bin/jukebox\fR and not
375 \fB/cgi-bin/jukebox\fR.
376 .SS "Authentication Configuration"
378 .B allow \fIUSERNAME\fR \fIPASSWORD\fR
379 Specify a username/password pair.
381 .B password \fIPASSWORD\fR
384 .B trust \fIUSERNAME\fR
385 Allow \fIUSERNAME\fR to perform privileged operations such as shutting
386 down or reconfiguring the daemon, or becoming another user.
389 Specifies the user to run as. Only makes sense if invoked as root (or
392 .B username \fIUSERNAME\fR
393 Specify username. The default is taken from the environment variable
396 Configuration files are read in the following order:
400 .I pkgconfdir/config.private
401 Should be readable only by the jukebox group, and contain \fBallow\fR
402 commands for authorised users.
404 .I pkgconfdir/config.\fRUSER
405 Per-user system-controlled client configuration. Optional but if it
406 exists must be readable only by the relevant user. Would normally
407 contain a \fBpassword\fR directive.
409 .I ~\fRUSER\fI/.disorder/passwd
410 Per-user client configuration. Optional but if it exists must be
411 readable only by the relevant user. Would normally contain a
412 \fBpassword\fR directive.
413 .SH "GLOBAL PREFERENCES"
414 These are the values set with \fBset-global\fR.
417 If this is set an nonempty then randomly played tracks will always have at
418 least one of the listed tags.
420 Tags can contain any printing character except comma. Leading and trailing
421 spaces are not significant but internal spaces are. Tags in a list are
425 If this is set an nonempty then randomly played tracks will never have any of
429 If unset or \fByes\fR then play is enabled. Otherwise it is disabled. Use
430 \fBdisable\fR rather than setting it directly.
433 If unset or \fByes\fR then random play is enabled. Otherwise it is disabled.
434 Use \fBdisable\fR rather than setting it directly.
436 .SS "Raw Protocol Players"
437 Raw protocol players are expected to use the \fBdisorder\fR libao driver.
438 Programs that use libao generally have command line options to select the
439 driver and pass options to it.
441 The known driver options are:
444 The file descriptor to write to. If this is not specified then the driver
445 looks like the environment variable \fBDISORDER_RAW_FD\fR. If that is not set
446 then the default is 1 (i.e. standard output).
449 If this is set to a nonzero value then the driver will call \fB_exit\fR(2) if a
450 write to the output file descriptor fails. This is a workaround for buggy
451 players such as \fBogg123\fR that ignore write errors.
453 When \fBdisorder.cgi\fR wants to generate a page for an action it searches the
454 directories specified with \fBtemplates\fR for a matching file. It is
455 suggested that you leave the distributed templates unchanged and put
456 any customisations in an earlier entry in the template path.
458 The supplied templates are:
461 Display information about DisOrder.
464 Navigates through the track database to choose a track to play. The
465 \fBdir\fR argument gives the directory to look in; if it is missing
466 then the root directory is used.
469 Provides a front end to \fBchoose.html\fR which allows subsets of the top level
470 directories to be selected by initial letter.
473 The "front page", which usually shows the currently playing tracks and
475 Gets an HTTP \fBRefresh\fR header.
477 If the \fBmgmt\fR CGI argument is set to \fBtrue\fR then we include extra
478 buttons for moving tracks up and down in the queue. There is some logic in
479 \fBdisorder.cgi\fR to ensure that \fBmgmt=true\fR is preserved across refreshes
480 and redirects back into itself, but URLs embedded in web pages must include it
484 Views preferences. If the \fBfile\fR, \fBname\fR and \fBvalue\fR arguments are
485 all set then that preference is modified; if \fBfile\fR and \fBname\fR are set
486 but not \fBvalue\fR then the preference is deleted.
489 Lists recently played tracks.
492 Presents search results.
495 Primitive volume control.
497 Additionally, other standard files are included by these:
500 Included at the end of the main content \fB<DIV>\fR element.
503 Included at the start of the \fB<BODY>\fR element.
506 Included in the \fB<HEAD>\fR element.
509 Contains the default DisOrder stylesheet. You can override this by editing the
510 CSS or by replacing it all with a \fB<LINK>\fR to an external stylesheet.
512 Templates are ASCII files containing HTML documents, with an expansion
513 syntax to enable data supplied by the implementation to be inserted.
515 If you want to use characters outside the ASCII range, use either the
516 appropriate HTML entity, e.g. \fBé\fR, or an SGML numeric
517 character reference, e.g. \fBý\fR. Use \fB@\fR to insert a
518 literal \fB@\fR without falling foul of the expansion syntax.
519 .SS "Expansion Syntax"
520 Expansions are surrounded by at ("@") symbols take the form of a keyword
521 followed by zero or more arguments. Arguments may either be quoted by curly
522 brackets ("{" and "}") or separated by colons (":"). Both kinds may be mixed
523 in a single expansion, though doing so seems likely to cause confusion.
524 The descriptions below contain suggested forms for each
527 Leading and trailing whitespace in unquoted arguments is ignored, as is
528 whitespace (including newlines) following a close bracket ("}").
530 Arguments are recursively expanded before being interpreted, except for
531 \fITEMPLATE\fR arguments. These are expanded (possibly more than once) to
532 produce the final expansion.
533 (More than once means the same argument being expanded more than once
534 for different tracks or whatever, not the result of the first
535 expansion itself being re-expanded.)
537 Strings constructed by expansions (i.e. not literally copied from the template
538 text) are SGML-quoted: any character which does not stand for itself in #PCDATA
539 or a quoted attribute value is replaced by the appropriate numeric character
542 The exception to this is that such strings are \fInot\fR quoted when they are
543 generated in the expansion of a parameter.
545 In the descriptions below, the current track means the one set by
546 \fB@playing@\fR, \fB@recent@\fR or \fB@queue@\fR, not the one that is playing.
547 If none of these expansions are in force then there is no current track.
548 \fIBOOL\fR should always be either \fBtrue\fR or \fBfalse\fR.
550 The following expansion keywords are defined:
552 .B @#{\fICOMMENT\fB}@
556 The current action. This reports
558 if the action is really
564 .B @and{\fIBOOL\fB}{\fIBOOL\fB}\fR...\fB@
565 If there are no arguments, or all the arguments are \fBtrue\fB, then expands to
566 \fBtrue\fR, otherwise to \fBfalse\fR.

575 The base name part of \fIPATH\fR.
577 .B @choose{\fIWHAT\fB}{\fITEMPLATE\fB}@
578 Expands \fITEMPLATE\fR repeatedly for each file or directory under
579 \fB@arg:directory@\fR.
580 \fIWHAT\fR should be either \fBfile\fR or \fBdirectory\fR.
581 Use \fB@file@\fR to get the display name or filename of the file or
583 Usually used in \fBchoose.html\fR.
586 The directory of the current directory component, in \fB@navigate@\fR.
588 .B @dirname{\fIPATH\fB}@
589 The directory part of \fIPATH\fR.
592 Expands to \fBtrue\fR if play is currently enabled, otherwise to \fBfalse\fR.
594 .B @eq{\fIA\fB}{\fIB\fB}
595 Expands to \fBtrue\fR if \fIA\fR and \fIB\fR are identical, otherwise to
599 Expands to the filename of the current file or directory, inside the template
600 argument to \fBchoose\fR.
602 .B @files{\fITEMPLATE\fB}
603 Expands \fITEMPLATE\fB once for each file indicated by the \fBdirectory\fR CGI
604 arg if it is present, or otherwise for the list of files counted by \fBfiles\fR
605 with names \fB0_file\fR, \fB1_file\fR etc.
608 The full path of the current directory component, in \fB@navigate@\fR.
611 The ID of the current track.
613 .B @if{\fIBOOL\fB}{\fITRUEPART\fB}{\fIFALSEPART\fB}@
614 If \fIBOOL\fR expands to \fBtrue\fR then expands to \fITRUEPART\fR, otherwise
615 to \fIFALSEPART\fR (which may be omitted).
617 .B @include:\fIPATH\fR@
618 Include the named file as if it were a template file. If \fIPATH\fR
619 starts with a \fB/\fR then it is used as-is; otherwise, ".html" is
620 appended and the template path is searched.
623 Expands to the index of the current file in \fB@queue@\fR, \fB@recent@\fR or
627 Expands to \fBtrue\fR if there are any directories in \fB@arg:directory@\fR,
628 otherwise to \fBfalse\fR.
631 Expands to \fBtrue\fR if there are any files in \fB@arg:directory@\fR,
632 otherwise to \fBfalse\fR.
635 Expands to \fBtrue\fR if this is the first repetition of a \fITEMPLATE\fR
636 argument in a loop (\fB@queue\fR or similar), otherwise to \fBfalse\fR.
639 Expands to \fBtrue\fR if this is the last repetition of a \fITEMPLATE\fR in a
640 loop, otherwise to \fBfalse\fR.

651 otherwise to \fBfalse\fR.
653 .B @label:\fINAME\fR\fB@
654 Expands to the value of label \fINAME\fR. See the shipped \fIoptions.labels\fR
655 file for full documentation of the labels used by the standard templates.
658 Expands to the length of the current track.
660 .B @navigate{\fIDIRECTORY\fB}{\fITEMPLATE\fB}
661 Expands \fITEMPLATE\fR for each component of \fIDIRECTORY\fR in turn.
662 Use \fB@dirname\fR and \fB@basename@\fR to get the components of the path to
664 Usually used in \fBchoose.html\fR.
666 .B @ne{\fIA\fB}{\fIB\fB}
667 Expands to \fBtrue\fR if \fIA\fR and \fIB\fR differ, otherwise to \fBfalse\fR.
670 Expands to the number of files from \fB@files\fR (above).
673 Expands to a string including the time and process ID, intended to be
674 unique across invocations.
677 Expands to \fBfalse\fR if \fIBOOL\fR is \fBtrue\fR, otherwise to
680 .B @or{\fIBOOL\fB}{\fIBOOL\fB}\fR...\fB@
681 If at least one argument is \fBtrue\fB, then expands to \fBtrue\fR, otherwise
685 Expands to \fBeven\fR or \fBodd\fR depending on whether the current track is at
686 an even or odd position in \fB@queue@\fR, \fB@recent@\fR or \fB@files@\fR.
688 .B @part{\fICONTEXT\fB}{\fIPART\fB}@
689 Expands to track name part \fIPART\fR using context \fICONTEXT\fR for the
690 current track. The context may be omitted (and normally would be) and defaults
693 .B @part{\fICONTEXT\fB}{\fIPART\fB}{\fITRACK\fB}@
694 Expands to track name part \fIPART\fR using context \fICONTEXT\fR for
695 \fITRACK\fR. In this usage the context may not be omitted.
698 Expands to \fBtrue\fR if the current track is paused, else \fBfalse\fR.
700 .B @playing{\fITEMPLATE\fB}@
701 Expands \fITEMPLATE\fR using the playing track as the current track.
703 .B @pref{\fITRACK\fB}{\fIKEY\fB}@
704 Expand to the track preference, or the empty string if it is not set.
707 Expands to the name of the current preference, in the template
708 argument of \fB@prefs@\fR.
710 .B @prefs{\fIFILE\fB}{\fITEMPLATE\fB}@
711 Expands \fITEMPLATE\fR repeatedly, for each preference of track
713 Use \fB@prefname@\fR and \fB@prefvalue@\fR to get the name and value.
716 Expands to the value of the current preference, in the template
717 argument of \fB@prefs@\fR.
719 .B @queue{\fITEMPLATE\fB}@
720 Expands \fITEMPLATE\fR repeatedly using the each track on the queue in turn as
721 the current track. The track at the head of the queue comes first.
724 Expands to \fBtrue\fR if random play is currently enabled, otherwise to
727 .B @recent{\fITEMPLATE\fB}@
728 Expands \fITEMPLATE\fR repeatedly using the each recently played track in turn
729 as the current track. The most recently played track comes first.
731 .B @resolve{\fITRACK\fB}@
732 Resolve aliases for \fITRACK\fR and expands to the result.
734 .B @search{\fIPART\fB}\fR[\fB{\fICONTEXT\fB}\fR]\fB{\fITEMPLATE\fB}@
735 Expands \fITEMPLATE\fR once for each group of search results that have
736 a common value of track part \fIPART\fR.
737 The groups are sorted by the value of the part.
742 within the template will apply to one of the tracks in the group.
744 If \fICONTEXT\fR is specified it should be either \fBsort\fR or \fBdisplay\fR,
745 and determines the context for \fIPART\fR. The default is \fBsort\fR. Usually
746 you want \fBdisplay\fR for everything except the title and \fBsort\fR for the
747 title. If you use \fBsort\fR for artist and album then you are likely to get
751 Expands to the server's version string.
753 .B @shell{\fICOMMAND\fB}@
754 Expands to the output of \fICOMMAND\fR executed via the shell. \fBsh\fR is
755 searched for using \fBPATH\fR. If the command fails then this is logged but
759 In \fB@queue@\fR and \fB@recent@\fR, expands to the state of the current
760 track. Otherwise the empty string. Known states are:
764 The player terminated with nonzero status, but not because the track was
768 A scratch, in the queue.
771 No player could be found.
777 A randomly chosen track, in the queue.
780 This track was scratched.
783 An explicitly queued track, in the queue.
786 Some additional states only apply to playing tracks, so will never be seen in
787 the queue or recently-played list:
791 The track has been paused.
794 Interrupted because the server is shutting down.
797 This track is currently playing.
801 Expands to the server statistics.
804 Expands to the URL of the current page. Typically used in
806 arguments. If there is a
808 argument then it is changed to a fresh value.
813 .B @trackstate{\fIPATH\fB}@
814 Expands to the current track state: \fBplaying\fR if the track is actually
815 playing now, \fBqueued\fR if it is queued or the empty string otherwise.
817 .B @transform{\fIPATH\fB}{\fITYPE\fB}{\fICONTEXT\fB}@
818 Transform a path according to \fBtransform\fR (see above).
819 \fIPATH\fR should be a raw filename (of a track or directory).
820 \fITYPE\fR should be the transform type (e.g. \fItrack\fR or \fIdir\fR).
821 \fICONTEXT\fR should be the context, and can be omitted (the default
825 Expands to the canonical URL as defined in \fIpkgconfdir/config\fR.
827 .B @urlquote{\fISTRING\fB}@
828 URL-quote \fISTRING\fR.
831 Expands to \fBdisorder.cgi\fR's version string.
833 .B @volume:\fISPEAKER\fB@
834 The volume on the left or right speaker. \fISPEAKER\fR must be \fBleft\fB or
838 When the current track was played (or when it is expected to be played, if it
839 has not been played yet)
842 Who submitted the current track.
844 This is a file called \fIoptions\fR, searched for in the same manner
845 as templates. It includes numerous options for the control of the web
846 interface. The general syntax is the same as the main configuration
847 file, except that it should be encoded using UTF-8 (though this might
848 change to the current locale's character encoding; stick to ASCII to
851 The shipped \fIoptions\fR file includes four standard options files.
855 The default labels file. You wouldn't normally edit this directly - instead
856 supply your own commands in \fIoptions.user\fR. Have a look at the shipped
857 version of the file for documentation of labels used by the standard templates.
860 A user options file. Here you should put any overrides for the default
861 labels and any extra labels required by your modified templates.
863 Valid directives are:
865 .B columns \fINAME\fR \fIHEADING\fR...
866 Defines the columns used in \fB@playing@\fR and \fB@recent@\fB. \fINAME\fR
867 must be either \fBplaying\fR, \fBrecent\fR or \fBsearch\fR.
868 \fIHEADING\fR... is a list of
869 heading names. If a column is defined more than once then the last definitions
872 The heading names \fBbutton\fR, \fBlength\fR, \fBwhen\fR and \fBwho\fR
875 .B include \fIPATH\fR
876 Includes another file. If \fIPATH\fR starts with a \fB/\fR then it is
877 taken as is, otherwise it is searched for in the template path.
879 .B label \fINAME\fR \fIVALUE\fR
880 Define a label. If a label is defined more than once then the last definition
883 Some labels are defined inside \fBdisorder.cgi\fR and others by the
884 default templates. You can define your own labels and use them inside
887 When an undefined label is expanded, if it has a dot in its name then
888 the part after the final dot is used as its value. Otherwise the
889 whole name is used as the value.
891 Labels are no longer documented here, see the shipped \fIoptions.labels\fR file
893 .SH "REGEXP SUBSTITUTION RULES"
894 Regexps are PCRE regexps, as defined in \fBpcrepattern\fR(3). The
895 only option used is \fBPCRE_UTF8\fR. Remember that the configuration
896 file syntax means you have to escape backslashes and quotes inside
899 In a \fISUBST\fR string the following sequences are interpreted
903 These expand to the first to ninth bracketed subexpression.
906 This expands to the matched part of the subject string.
909 This expands to a single \fB$\fR symbol.
911 All other pairs starting with \fB$\fR are undefined (and might be used
912 for something else in the future, so don't rely on the current
915 If \fBi\fR is present in \fIREFLAGS\fR then the match is case-independent. If
916 \fBg\fR is present then all matches are replaced, otherwise only the first
919 What the web interface actually does is terminated by the \fBaction\fR CGI
920 argument. The values listed below are supported.
922 Except as specified, all actions redirect back to the \fBplaying.html\fR
923 template unless the \fBback\fR argument is present, in which case the URL it
924 gives is used instead.
926 Redirection to \fBplaying.html\fR preserves \fBmgmt=true\fR if it is present.
929 Move track \fBid\fR by offset \fBdelta\fR.
932 Play track \fBfile\fR, or if that is missing then play all the tracks in
936 Don't change any state, but instead compute a suitable refresh time and include
937 that in an HTTP header. Expands the \fBplaying.html\fR template rather than
940 This is the default if \fBaction\fR is missing.
943 Disables random play.
949 Disables play completely.
955 Pauses the current track.
958 Remove track \fBid\fR.
961 Resumes play after a pause.
964 Scratch the playing track. If \fBid\fR is present it must match the playing
968 Change the volume by \fBdelta\fR, or if that is missing then set it to the
969 values of \fBleft\fR and \fBright\fR. Expands to the \fBvolume.html\fR template
970 rather than redirecting.
973 Adjust preferences from the \fBprefs.html\fR template (which it then expands
974 rather than redirecting).
978 is set then the cooked interface is assumed. The value of
980 is used to determine which trackname preferences are set. By default the
982 context is adjusted but this can be overridden with the
986 argument is checked; if it is set then random play is enabled for that track,
987 otherwise it is disabled.
993 arguments are set then they are used to set a single preference.
995 Otherwise if just the
997 argument is set then that preference is deleted.
999 It is recommended that links to the \fBprefs\fR action use \fB@resolve@\fR to
1000 enure that the real track name is always used. Otherwise if the preferences
1001 page is used to adjust a trackname_ preference, the alias may change, leading
1002 to the URL going stale.
1005 This action is generated automatically when an error occurs connecting to the
1006 server. The \fBerror\fR label is set to an indication of what the error is.
1007 .SH "TRACK NAME PARTS"
1008 The traditional track name parts are \fBartist\fR, \fBalbum\fR and \fBtitle\fR,
1009 with the obvious intended meaning. These are controlled by configuration and
1010 by \fBtrackname_\fR preferences.
1012 In addition there are two built-in parts, \fBpath\fR which is the whole path
1013 name and \fBext\fR which is the filename extension, including the initial dot
1014 (or the empty string if there is not extension).
