20 | .SH NAME | |
21 | pkgconfdir/config - DisOrder jukebox configuration | |
22 | .SH DESCRIPTION | |
23 | The purpose of DisOrder is to organize and play digital audio files, under the | |
c0c23a60 RK |
24 | control of multiple users. |
25 | \fIpkgconfdir/config\fR is the primary configuration file but this | |
26 | man page currently documents all of its various configuration files. | |
460b9539 | 27 | .SS Tracks |
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 | |
30 | instance, "*.mp3"). | |
31 | .PP | |
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 | |
c0c23a60 RK |
34 | player. |
35 | See \fBdisorder\fR(3) for more details about this. | |
460b9539 | 36 | .PP |
c0c23a60 RK |
37 | Each track can have a set of preferences associated with it. |
38 | These are simple key-value pairs; they can be used for anything you | |
39 | like, but a number of keys have specific meanings. | |
40 | See \fBdisorder\fR(1) for more details about these. | |
460b9539 | 41 | .SS "Track Names" |
42 | Track names are derived from filenames under the control of regular | |
43 | expressions, rather than attempting to interpret format-specific embedded name | |
c0c23a60 RK |
44 | information. |
45 | They can be overridden by setting preferences. | |
460b9539 | 46 | .PP |
47 | Names for display are distinguished from names for sorting, so with the right | |
48 | underlying filenames an album can be displayed in its original order even if | |
49 | the displayed track titles are not lexically sorted. | |
50 | .SS "Server State" | |
51 | A collection of global preferences define various bits of server state: whether | |
52 | random play is enabled, what tags to check for when picking at random, etc. | |
53 | .SS "Users And Access Control" | |
c0c23a60 RK |
54 | DisOrder distinguishes between multiple users. |
55 | This is for access control and reporting, not to provide different | |
56 | views of the world: i.e. preferences and so on are global. | |
460b9539 | 57 | .PP |
eb5dc014 | 58 | Each user has an associated set of rights which contorl which commands they may |
c0c23a60 RK |
59 | execute. |
60 | Normally you would give all users most rights, and expect them to | |
eb5dc014 RK |
61 | cooperate (they are after all presumed to be in a shared sound environment). |
62 | .PP | |
63 | The full set of rights are: | |
64 | .TP | |
65 | .B read | |
66 | User can perform read-only operations | |
67 | .TP | |
68 | .B play | |
69 | User can add tracks to the queue | |

71 | .B "move any" | |
72 | User can move any track | |
73 | .TP | |
74 | .B "move mine" | |
75 | User can move their own tracks | |
76 | .TP | |
77 | .B "move random" | |
78 | User can move randomly chosen tracks | |
79 | .TP | |
80 | .B "remove any" | |
81 | User can remove any track | |
82 | .TP | |
83 | .B "remove mine" | |
84 | User can remove their own tracks | |
85 | .TP | |
86 | .B "remove random" | |
87 | User can remove randomly chosen tracks | |
88 | .TP | |
89 | .B "scratch any" | |
90 | User can scratch any track | |
91 | .TP | |
92 | .B "scratch mine" | |
93 | User can scratch their own tracks | |
94 | .TP | |
95 | .B "scratch random" | |
96 | User can scratch randomly chosen tracks | |
97 | .TP | |
98 | .B volume | |
99 | User can change the volume | |
100 | .TP | |
101 | .B admin | |
102 | User can perform admin operations | |
103 | .TP | |
104 | .B rescan | |
105 | User can initiate a rescan | |
106 | .TP | |
107 | .B register | |
c0c23a60 RK |
108 | User can register new users. |
109 | Normally only the | |
eb5dc014 RK |
110 | .B guest |
111 | user would have this right. | |
112 | .TP | |
113 | .B userinfo | |
114 | User can edit their own userinfo | |
115 | .TP | |
116 | .B prefs | |
117 | User can modify track preferences | |
118 | .TP | |
119 | .B "global prefs" | |
120 | User can modify global preferences | |
121 | .TP | |
122 | .B pause | |
123 | User can pause/resume | |
460b9539 | 124 | .PP |
c0c23a60 RK |
125 | Access control is entirely used-based. |
126 | If you configure DisOrder to listen for TCP/IP connections then it will | |
127 | accept a connection from anywhere provided the right password is | |
128 | available. | |
129 | Passwords are never transmitted over TCP/IP connections in clear, | |
130 | but everything else is. | |
131 | The expected model is that host-based access control is imposed at | |
132 | the network layer. | |
460b9539 | 133 | .SS "Web Interface" |
134 | The web interface is controlled by a collection of template files, one for each | |
c0c23a60 RK |
135 | kind of page, and a collection of option files. |
136 | These are split up and separate from the main configuration file to | |
137 | make it more convenient to override specific bits. | |
460b9539 | 138 | .PP |
139 | The web interface connects to the DisOrder server like any other user, though | |
c0c23a60 RK |
140 | it is given a special privilege to "become" any other user. |
141 | (Thus, any process with the same UID as the web interface is very | |
142 | powerful as far as DisOrder goes. | |
143 | This model will be changed in a future version.) | |
460b9539 | 144 | .PP |
145 | Access control to the web interface is (currently) separate from DisOrder's own | |
146 | access control (HTTP authentication is required) but uses the same user | |
147 | namespace. | |
180dcdb0 | 148 | .SS "Searching And Tags" |
c0c23a60 RK |
149 | Search strings contain a list of search terms separated by spaces. |
150 | A search term can either be a single word or a tag, prefixed with "tag:". | |
180dcdb0 RK |
151 | .PP |
152 | Search words are compared without regard to letter case or accents; thus, all | |
153 | of the following will be considered to be equal to one another: | |
154 | .PP | |
155 | .nf | |
156 | LATIN CAPITAL LETTER E | |
157 | LATIN SMALL LETTER E | |
158 | LATIN CAPITAL LETTER E WITH GRAVE | |
159 | LATIN SMALL LETTER E WITH GRAVE | |
160 | LATIN CAPITAL LETTER E plus COMBINING GRAVE ACCENT | |
161 | LATIN SMALL LETTER E plus COMBINING GRAVE ACCENT | |
162 | .fi | |
163 | .PP | |
164 | The same rules apply to tags but in addition leading and trailing whitespace is | |
165 | disregarded and all whitespace sequences are treated as equal when they appear | |
166 | as internal whitespace. | |
167 | .PP | |
168 | Where several tags are listed, for instance the tags preference for a track, | |
c0c23a60 RK |
169 | the tags are separated by commas. |
170 | Therefore tags may not contain commas. | |
460b9539 | 171 | .SH "CONFIGURATION FILE" |
172 | .SS "General Syntax" | |
173 | Lines are split into fields separated by whitespace (space, tab, line | |
c0c23a60 RK |
174 | feed, carriage return, form feed). |
175 | Comments are started by the number sign ("#"). | |
460b9539 | 176 | .PP |
177 | Fields may be unquoted (in which case they may not contain spaces and | |
178 | may not start with a quotation mark or apostrophe) or quoted by either | |
c0c23a60 RK |
179 | quotation marks or apostrophes. |
180 | Inside quoted fields every character stands for itself, except that | |
181 | a backslash can only appear as part of one of the following escape sequences: | |
460b9539 | 182 | .TP |
183 | .B \e\e | |
184 | Backslash | |
185 | .TP | |
186 | .B \e" | |
187 | Quotation mark | |
188 | .\" " | |
189 | .TP | |
190 | .B \e' | |
191 | Apostrophe | |
192 | .TP | |
193 | .B \en | |
194 | Line feed | |
195 | .PP | |
196 | No other escape sequences are allowed. | |
197 | .PP | |
198 | Within any line the first field is a configuration command and any | |
c0c23a60 RK |
199 | further fields are parameters. |
200 | Lines with no fields are ignored. | |
460b9539 | 201 | .PP |
202 | After editing the config file use \fBdisorder reconfigure\fR to make | |
c0c23a60 RK |
203 | it re-read it. |
204 | If there is anything wrong with it the daemon will record a log | |
205 | message and ignore the new config file. | |
206 | (You should fix it before next terminating and restarting the daemon, | |
207 | as it cannot start up without a valid config file.) | |
eb5dc014 RK |
208 | .SS "Configuration Files" |
209 | Configuration files are read in the following order: | |
210 | .TP | |
211 | .I pkgconfdir/config | |
212 | .TP | |
213 | .I pkgconfdir/config.private | |
c0c23a60 RK |
214 | Should be readable only by the jukebox group. |
215 | Not really useful any more and will be abolished in future. | |
eb5dc014 RK |
216 | .TP |
217 | .I ~\fRUSER\fI/.disorder/passwd | |
c0c23a60 RK |
218 | Per-user client configuration. |
219 | Optional but if it exists must be readable only by the relevant user. | |
220 | Would normally contain a \fBpassword\fR directive. | |
5b14453f RK |
221 | .TP |
222 | .I pkgconfdir/config.\fRUSER | |
c0c23a60 RK |
223 | Per-user system-controlled client configuration. |
224 | Optional but if it exists must be readable only by the relevant user. | |
225 | Would normally contain a \fBpassword\fR directive. | |
5b14453f RK |
226 | .IP |
227 | The prefererred location for per-user passwords is \fI~/.disorder/passwd\fR and | |
c0c23a60 | 228 | \fBdisorder authorize\fR writes there now. |
460b9539 | 229 | .SS "Global Configuration" |
230 | .TP | |
231 | .B home \fIDIRECTORY\fR | |
c0c23a60 RK |
232 | The home directory for state files. |
233 | Defaults to | |
460b9539 | 234 | .IR pkgstatedir . |
659d87e8 | 235 | The server will create this directory on startup if it does not exist. |
460b9539 | 236 | .TP |
0c6bcae0 | 237 | .B plugins \fIPATH\fR |
c0c23a60 RK |
238 | Adds a directory to the plugin path. |
239 | (This is also used by the web interface.) | |
460b9539 | 240 | .IP |
241 | Plugins are opened the first time they are required and never after, | |
242 | so after changing a plugin you must restart the server before it is | |
243 | guaranteed to take effect. | |
40c30921 RK |
244 | .IP |
245 | If | |
246 | .B plugins | |
247 | is used without arguments the plugin path is cleared. | |
460b9539 | 248 | .SS "Server Configuration" |
249 | .TP | |
250 | .B alias \fIPATTERN\fR | |
251 | Defines the pattern use construct virtual filenames from \fBtrackname_\fR | |
252 | preferences. | |
253 | .IP | |
254 | Most characters stand for themselves, the exception being \fB{\fR which is used | |
255 | to insert a track name part in the form \fB{\fIname\fB}\fR or | |
256 | \fB{/\fIname\fB}\fR. | |
257 | .IP | |
258 | The difference is that the first form just inserts the name part while the | |
259 | second prefixes it with a \fB/\fR if it is nonempty. | |
260 | .IP | |
261 | The pattern should not attempt to include the collection root, which is | |
262 | automatically included, but should include the proper extension. | |
263 | .IP | |
264 | The default is \fB{/artist}{/album}{/title}{ext}\fR. | |

f9635e06 | 799 | modify the database after an upgrade. |
460b9539 | 800 | .SH "LIBAO DRIVER" |
801 | .SS "Raw Protocol Players" | |
802 | Raw protocol players are expected to use the \fBdisorder\fR libao driver. | |
803 | Programs that use libao generally have command line options to select the | |
804 | driver and pass options to it. | |
805 | .SS "Driver Options" | |
806 | The known driver options are: | |
807 | .TP | |
808 | .B fd | |
c0c23a60 RK |
809 | The file descriptor to write to. |
810 | If this is not specified then the driver looks like the environment | |
811 | variable \fBDISORDER_RAW_FD\fR. | |
812 | If that is not set then the default is 1 (i.e. standard output). | |
460b9539 | 813 | .TP |
814 | .B fragile | |
815 | If this is set to a nonzero value then the driver will call \fB_exit\fR(2) if a | |
c0c23a60 RK |
816 | write to the output file descriptor fails. |
817 | This is a workaround for buggy players such as \fBogg123\fR that ignore | |
818 | write errors. | |
460b9539 | 819 | .SH "WEB TEMPLATES" |
820 | When \fBdisorder.cgi\fR wants to generate a page for an action it searches the | |
c0c23a60 RK |
821 | directories specified with \fBtemplates\fR for a matching file. |
822 | It is suggested that you leave the distributed templates unchanged and put | |
460b9539 | 823 | any customisations in an earlier entry in the template path. |
824 | .PP | |
825 | The supplied templates are: | |
826 | .TP | |
827 | .B about.html | |
828 | Display information about DisOrder. | |
829 | .TP | |
830 | .B choose.html | |
c0c23a60 RK |
831 | Navigates through the track database to choose a track to play. |
832 | The \fBdir\fR argument gives the directory to look in; if it is missing | |
460b9539 | 833 | then the root directory is used. |
834 | .TP | |
835 | .B choosealpha.html | |
836 | Provides a front end to \fBchoose.html\fR which allows subsets of the top level | |
837 | directories to be selected by initial letter. | |
838 | .TP | |
d5b6ffd7 RK |
839 | .B new.html |
840 | Lists newly added tracks. | |
841 | .TP | |
460b9539 | 842 | .B playing.html |
843 | The "front page", which usually shows the currently playing tracks and | |
844 | the queue. | |
845 | Gets an HTTP \fBRefresh\fR header. | |
846 | .IP | |
847 | If the \fBmgmt\fR CGI argument is set to \fBtrue\fR then we include extra | |
c0c23a60 RK |
848 | buttons for moving tracks up and down in the queue. |
849 | There is some logic in \fBdisorder.cgi\fR to ensure that \fBmgmt=true\fR | |
850 | is preserved across refreshes and redirects back into itself, but | |
851 | URLs embedded in web pages must include it explicitly. | |
460b9539 | 852 | .TP |
853 | .B prefs.html | |
c0c23a60 RK |
854 | Views preferences. |
855 | If the \fBfile\fR, \fBname\fR and \fBvalue\fR arguments are | |
460b9539 | 856 | all set then that preference is modified; if \fBfile\fR and \fBname\fR are set |
857 | but not \fBvalue\fR then the preference is deleted. | |
858 | .TP | |
859 | .B recent.html | |
860 | Lists recently played tracks. | |
861 | .TP | |
862 | .B search.html | |
863 | Presents search results. | |
864 | .TP | |
865 | .B volume.html | |
866 | Primitive volume control. | |
867 | .PP | |
868 | Additionally, other standard files are included by these: | |
869 | .TP | |
870 | .B credits.html | |
871 | Included at the end of the main content \fB<DIV>\fR element. | |
872 | .TP | |
d5b6ffd7 | 873 | .B topbar.html |
e12da4d9 | 874 | Included at the start of the \fB<BODY>\fR element. |
875 | .TP | |
876 | .B topbarend.html | |
877 | Included at the end of the \fB<BODY>\fR element. | |
460b9539 | 878 | .TP |
879 | .B stdhead.html | |
880 | Included in the \fB<HEAD>\fR element. | |
881 | .TP | |
882 | .B stylesheet.html | |
c0c23a60 RK |
883 | Contains the default DisOrder stylesheet. |
884 | You can override this by editing the CSS or by replacing it all with | |
885 | a \fB<LINK>\fR to an external stylesheet. | |
460b9539 | 886 | .PP |
887 | Templates are ASCII files containing HTML documents, with an expansion | |
888 | syntax to enable data supplied by the implementation to be inserted. | |
889 | .PP | |
890 | If you want to use characters outside the ASCII range, use either the | |
891 | appropriate HTML entity, e.g. \fBé\fR, or an SGML numeric | |
c0c23a60 RK |
892 | character reference, e.g. \fBý\fR. |
893 | Use \fB@\fR to insert a literal \fB@\fR without falling foul of | |
894 | the expansion syntax. | |
460b9539 | 895 | .SS "Expansion Syntax" |
896 | Expansions are surrounded by at ("@") symbols take the form of a keyword | |
c0c23a60 RK |
897 | followed by zero or more arguments. |
898 | Arguments may either be quoted by curly brackets ("{" and "}") or separated | |
899 | by colons (":"). | |
900 | Both kinds may be mixed in a single expansion, though doing so seems | |
901 | likely to cause confusion. | |
902 | The descriptions below contain suggested forms for each expansion. | |
460b9539 | 903 | .PP |
904 | Leading and trailing whitespace in unquoted arguments is ignored, as is | |
905 | whitespace (including newlines) following a close bracket ("}"). | |
906 | .PP | |
907 | Arguments are recursively expanded before being interpreted, except for | |
c0c23a60 RK |
908 | \fITEMPLATE\fR arguments. |
909 | These are expanded (possibly more than once) to produce the final expansion. | |
460b9539 | 910 | (More than once means the same argument being expanded more than once |
911 | for different tracks or whatever, not the result of the first | |
912 | expansion itself being re-expanded.) | |
913 | .PP | |
914 | Strings constructed by expansions (i.e. not literally copied from the template | |
915 | text) are SGML-quoted: any character which does not stand for itself in #PCDATA | |
916 | or a quoted attribute value is replaced by the appropriate numeric character | |
917 | reference. | |
918 | .PP | |
919 | The exception to this is that such strings are \fInot\fR quoted when they are | |
920 | generated in the expansion of a parameter. | |
921 | .PP | |
922 | In the descriptions below, the current track means the one set by | |
923 | \fB@playing@\fR, \fB@recent@\fR or \fB@queue@\fR, not the one that is playing. | |
924 | If none of these expansions are in force then there is no current track. | |
925 | \fIBOOL\fR should always be either \fBtrue\fR or \fBfalse\fR. | |
926 | .SS "Expansions" | |
927 | The following expansion keywords are defined: | |
928 | .TP | |
929 | .B @#{\fICOMMENT\fB}@ | |
930 | Ignored. | |
931 | .TP | |
932 | .B @action@ | |

957 | \fB@arg:directory@\fR. | |
958 | \fIWHAT\fR should be either \fBfile\fR or \fBdirectory\fR. | |
959 | Use \fB@file@\fR to get the display name or filename of the file or | |

993 | to \fIFALSEPART\fR (which may be omitted). | |
994 | .TP | |
8f9616f1 RK |
995 | .B @image:\fINAME\fB@ |
996 | Expands to the (possibly relative) URL for image \fINAME\fR. | |
997 | .IP | |
998 | If there is a label \fBimages.\fINAME\fR then that will be the image base name. | |

1284 | .SH "WEB OPTIONS" | |
1285 | This is a file called \fIoptions\fR, searched for in the same manner | |
c0c23a60 RK |
1286 | as templates. |
1287 | It includes numerous options for the control of the web interface. | |
1288 | The general syntax is the same as the main configuration | |
460b9539 | 1289 | file, except that it should be encoded using UTF-8 (though this might |
1290 | change to the current locale's character encoding; stick to ASCII to | |
1291 | be safe). | |
1292 | .PP | |
1293 | The shipped \fIoptions\fR file includes four standard options files. | |
1294 | In order, they are: | |
1295 | .TP | |
1296 | .I options.labels | |
c0c23a60 RK |
1297 | The default labels file. |
1298 | You wouldn't normally edit this directly - instead supply your own commands | |
1299 | in \fIoptions.user\fR. | |
1300 | Have a look at the shipped version of the file for documentation of | |
1301 | labels used by the standard templates. | |
460b9539 | 1302 | .TP |
1303 | .I options.user | |
c0c23a60 RK |
1304 | A user options file. |
1305 | Here you should put any overrides for the default labels and any | |
1306 | extra labels required by your modified templates. | |
460b9539 | 1307 | .PP |
1308 | Valid directives are: | |
1309 | .TP | |
1310 | .B columns \fINAME\fR \fIHEADING\fR... | |
c0c23a60 RK |
1311 | Defines the columns used in \fB@playing@\fR and \fB@recent@\fB. |
1312 | \fINAME\fR must be either \fBplaying\fR, \fBrecent\fR or \fBsearch\fR. | |
1313 | \fIHEADING\fR... is a list of heading names. | |
1314 | If a column is defined more than once then the last definitions is used. | |
460b9539 | 1315 | .IP |
1316 | The heading names \fBbutton\fR, \fBlength\fR, \fBwhen\fR and \fBwho\fR | |
1317 | are built in. | |
1318 | .TP | |
1319 | .B include \fIPATH\fR | |
c0c23a60 RK |
1320 | Includes another file. |
1321 | If \fIPATH\fR starts with a \fB/\fR then it is taken as is, otherwise | |
1322 | it is searched for in the template path. | |
460b9539 | 1323 | .TP |
1324 | .B label \fINAME\fR \fIVALUE\fR | |
c0c23a60 RK |
1325 | Define a label. |
1326 | If a label is defined more than once then the last definition is used. | |
460b9539 | 1327 | .SS Labels |
1328 | Some labels are defined inside \fBdisorder.cgi\fR and others by the | |
c0c23a60 RK |
1329 | default templates. |
1330 | You can define your own labels and use them inside a template. | |
460b9539 | 1331 | .PP |
1332 | When an undefined label is expanded, if it has a dot in its name then | |
c0c23a60 RK |
1333 | the part after the final dot is used as its value. |
1334 | Otherwise the whole name is used as the value. | |
460b9539 | 1335 | .PP |
1336 | Labels are no longer documented here, see the shipped \fIoptions.labels\fR file | |
1337 | instead. | |
1338 | .SH "REGEXP SUBSTITUTION RULES" | |
c0c23a60 RK |
1339 | Regexps are PCRE regexps, as defined in \fBpcrepattern\fR(3). |
1340 | The only option used is \fBPCRE_UTF8\fR. | |
1341 | Remember that the configuration file syntax means you have to | |
1342 | escape backslashes and quotes inside quoted strings. | |
460b9539 | 1343 | .PP |
1344 | In a \fISUBST\fR string the following sequences are interpreted | |
1345 | specially: | |
1346 | .TP | |
1347 | .B $1 \fR... \fB$9 | |
1348 | These expand to the first to ninth bracketed subexpression. | |
1349 | .TP | |
1350 | .B $& | |
1351 | This expands to the matched part of the subject string. | |
1352 | .TP | |
1353 | .B $$ | |
1354 | This expands to a single \fB$\fR symbol. | |
1355 | .PP | |
1356 | All other pairs starting with \fB$\fR are undefined (and might be used | |
1357 | for something else in the future, so don't rely on the current | |
1358 | behaviour.) | |
1359 | .PP | |
c0c23a60 RK |
1360 | If \fBi\fR is present in \fIREFLAGS\fR then the match is case-independent. |
1361 | If \fBg\fR is present then all matches are replaced, otherwise only the first | |
460b9539 | 1362 | match is replaced. |
1363 | .SH "ACTIONS" | |
1364 | What the web interface actually does is terminated by the \fBaction\fR CGI | |
c0c23a60 RK |
1365 | argument. |
1366 | The values listed below are supported. | |
460b9539 | 1367 | .PP |
1368 | Except as specified, all actions redirect back to the \fBplaying.html\fR | |
1369 | template unless the \fBback\fR argument is present, in which case the URL it | |
1370 | gives is used instead. | |
1371 | .PP | |
1372 | Redirection to \fBplaying.html\fR preserves \fBmgmt=true\fR if it is present. | |
1373 | .TP 8 | |
1374 | .B "move" | |
1375 | Move track \fBid\fR by offset \fBdelta\fR. | |
1376 | .TP | |
1377 | .B "play" | |
1378 | Play track \fBfile\fR, or if that is missing then play all the tracks in | |
1379 | \fBdirectory\fR. | |
1380 | .TP | |
1381 | .B "playing" | |
1382 | Don't change any state, but instead compute a suitable refresh time and include | |
c0c23a60 RK |
1383 | that in an HTTP header. |
1384 | Expands the \fBplaying.html\fR template rather than redirecting. | |
460b9539 | 1385 | .IP |
1386 | This is the default if \fBaction\fR is missing. | |
1387 | .TP | |
0d350ff0 | 1388 | .B "random\-disable" |
460b9539 | 1389 | Disables random play. |
1390 | .TP | |
0d350ff0 | 1391 | .B "random\-enable" |
460b9539 | 1392 | Enables random play. |
1393 | .TP | |
1394 | .B "disable" | |
1395 | Disables play completely. | |

1397 | .B "enable" | |
1398 | Enables play. | |
1399 | .TP | |
1400 | .B "pause" | |
1401 | Pauses the current track. | |
1402 | .TP | |
1403 | .B "remove" | |
1404 | Remove track \fBid\fR. | |
1405 | .TP | |
1406 | .B "resume" | |
1407 | Resumes play after a pause. | |
1408 | .TP | |
1409 | .B "scratch" | |
c0c23a60 RK |
1410 | Scratch the playing track. |
1411 | If \fBid\fR is present it must match the playing track. | |
460b9539 | 1412 | .TP |
1413 | .B "volume" | |
1414 | Change the volume by \fBdelta\fR, or if that is missing then set it to the | |
c0c23a60 RK |
1415 | values of \fBleft\fR and \fBright\fR. |
1416 | Expands to the \fBvolume.html\fR template rather than redirecting. | |
460b9539 | 1417 | .TP |
1418 | .B "prefs" | |
1419 | Adjust preferences from the \fBprefs.html\fR template (which it then expands | |
1420 | rather than redirecting). | |
1421 | .IP | |
1422 | If | |
1423 | .B parts | |
c0c23a60 RK |
1424 | is set then the cooked interface is assumed. |
1425 | The value of | |
460b9539 | 1426 | .B parts |
c0c23a60 RK |
1427 | is used to determine which trackname preferences are set. |
1428 | By default the | |
460b9539 | 1429 | .B display |
1430 | context is adjusted but this can be overridden with the | |
1431 | .B context | |
c0c23a60 RK |
1432 | argument. |
1433 | Also the | |
460b9539 | 1434 | .B random |
1435 | argument is checked; if it is set then random play is enabled for that track, | |
1436 | otherwise it is disabled. | |
1437 | .IP | |
1438 | Otherwise if the | |
1439 | .B name | |
1440 | and | |
1441 | .B value | |
1442 | arguments are set then they are used to set a single preference. | |
1443 | .IP | |
1444 | Otherwise if just the | |
1445 | .B name | |
1446 | argument is set then that preference is deleted. | |
1447 | .IP | |
1448 | It is recommended that links to the \fBprefs\fR action use \fB@resolve@\fR to | |
c0c23a60 RK |
1449 | enure that the real track name is always used. |
1450 | Otherwise if the preferences page is used to adjust a trackname_ preference, | |
1451 | the alias may change, leading to the URL going stale. | |
460b9539 | 1452 | .TP |
1453 | .B "error" | |
1454 | This action is generated automatically when an error occurs connecting to the | |
c0c23a60 RK |
1455 | server. |
1456 | The \fBerror\fR label is set to an indication of what the error is. | |
460b9539 | 1457 | .SH "TRACK NAME PARTS" |
1458 | The traditional track name parts are \fBartist\fR, \fBalbum\fR and \fBtitle\fR, | |
c0c23a60 RK |
1459 | with the obvious intended meaning. |
1460 | These are controlled by configuration and by \fBtrackname_\fR preferences. | |
460b9539 | 1461 | .PP |
1462 | In addition there are two built-in parts, \fBpath\fR which is the whole path | |
