It contains two built-in streamers: + the http streamer and the ortp streamer. + + para_audiod runs on the client side and connects to + para_server. The audio stream is read back and sent through + any of paraslash's filters (mp3 decoder, ogg vorbis decoder, + volume normalizer,...) and the resulting stream is written to + an external program's standard in, usually an audio player, + like para_play that uses alsa. It is possible to grab the + stream at any position in the filter chain. + + The receiving/filtering software is also available as + standalone command line tool: para_recv grabs the http or ortp + stream and writes to stdout; para_filter reads from stdin, + converts the stream according to the given --filter command + line options and writes the transformed stream to stdout. + +mysql-based audio file selector: +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + the (optional) mysql database tool manages some statistics on + your audio files. It contacts the mysql server to decide which + song to play next by sending a user-defined sql-query. This + allows rather sophisticated configurations and is explained + in detail in README.mysql. + +small memory footprint: +~~~~~~~~~~~~~~~~~~~~~~~ + paraslash is lightweight. The stripped binary of para_server + with all its features compiled in (mysql/dopey dbtool, + mp3/ogg support, http/ortp support) is about 100K on i386 + under Linux. para_audiod is even smaller. + +command line interface, including shell: +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + para_client without arguments starts interactive (shell) + mode. Otherwise, command is sent to para_server directly + and output is dumped to stdout. This can be used by any + scripting language to produce user interfaces with very little + programming effort. + +authentication/encryption via openssl: +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + All connections between para_server and para_client are + encrypted by default. For each user of paraslash you must + create a public/secret key pair for authentication/encryption. + +various user interfaces and utilities: +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + o para_gui. Curses based interface, displays information in a + curses window and can be used to easily control para_server + and para_audiod. + + o para_sdl_gui. Shows pictures (on a per song basis) and + other information about the current audio file. Can be used + as a screen saver. + + o para_krell. A gkrellm2 plugin that shows small pics and is + able to launch 27 different commands by clicking on the image. + + o para_slider. User-friendly stream creator for people who + don't like their keyboard. + + o para_dbadm. Simple curses interface for changing attributes. + + o para_fade.

By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Library General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) 19yy + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Otherwise doublecheck what is logged by +para_server and use the --loglevel option of para_recv to increase +verbosity. + +Configure para_audiod +~~~~~~~~~~~~~~~~~~~~~ +In order to automatically start the right decoder at the right time +and to offer to the clients some information on the current audio +stream and on paraslash's internal state, you should run the local +audio daemon, para_audiod, on every machine that is supposed to play +the audio stream. Try + + para_audiod -h + +for help. Usually you have to specify at least server_host as the +receiver specifier, like this: + + -r http:-i:server_host + +The prefered way to use para_audiod is to run it once at system start +as an unprivileged user. para_audiod needs to create a "well-known" +socket for the clients to connect to. If you want to change the +default socket (e.g. because you do not have write access for the +directory where the socket resides), use the -s option or the config +file to change the default. Note that in this case you'll also have +to specify the same value for para_audioc's -s option. + +If para_server is playing, you should be able to listen to the audio +stream as soon as para_audiod is started. Once it is running, try + + para_audioc stat + +That should dump some information to stdout. Other commands include + + para_audioc off + para_audioc on + para_audioc sb + para_audioc term + para_audioc cycle + + +Start para_gui +~~~~~~~~~~~~~~ +para_gui reads the output of "para_audioc stat" and displays that +information in a curses window. It also allows you to bind keys to +arbitrary commands. There are several flavours of key-bindings: + + o internal: These are the built-in commands that can not be + changed (help, quit, loglevel, version...). + + o external: Shutdown curses before launching the given command. + Useful for starting other ncurses programs from within + para_gui, e.g. aumix or para_dbadm. Or, use + + para_client mbox + + to write a mailbox containing one mail for each file + in the mysql database and start mutt from within para_gui + to browse your collection! + + o display: Launch the command and display its stdout in + para_gui's bottom window. + + o para: Like display, but start "para_client " instead of "". + + +That's all, congratulations. Check out all the other optional gimmics! + +Troubles? +~~~~~~~~~ +If something went wrong, look at the output.

However, there + are many more commands. + + For audio streaming, at least one sender must be activated. + At the moment, paraslash contains two internal senders: + + The http sender is recommended for public streams that can + be played by any player like mpg123, xmms, winamp... + + The ortp sender is recommended for LAN streaming and for + private streams that require authentication. + + It is possible to activate more than one sender simultaneously. + All senders have the same set of commands that allow to + control the access permissions of the stream. + + para_server needs a database tool to work, mainly to determine + which song to stream next. There are two database tools + available: mysql and dopey. The former is recommended as dopey + is only meant as a fallback and as a starting point for people + that want to write their own database tool for paraslash. + + The mysql database tool connects to a mysql server which + holds information on your audio files. It has several unusual + features, see README.mysql for details. + +- para_client (obligatory): + + The client program to connect to para_server. + +- para_recv (optional) + + A command line http/ortp stream grabber. + +- para_filter (optional) + + An filter program that converts from stdin and writes to + stdout. This one is independent from the rest of paraslash, + so it might be useful also for different purposes. + + para_filter combines an mp3 decoder an oggvorbis decoder + and a volume normalzer. New filters can be added easily due + to the modular design. If more than one filter is specified, + the given filters are 'piped' together in-memory, i.e. without + calling any of the read(2)/write(2)/select(2) etc. functions. + +- para_play (optional) + + A small wav/raw player for alsa. + +- para_audiod (optional, but recommended): + + The local daemon that starts playback and collects information + from para_server to be forwarded to local clients. + + para_audiod reads the audio stream from the network if + para_server indicates that there is a stream available. It may + be sent through any of the supported filters (see para_filter + above) before the result is fed to the output software + (default: para_play) which must be capable of reading from + stdin, but is not restricted otherwise. + +- para_audioc (optional, but recommended) + + A small client that can talk to para_audiod. Used to control + para_audiod and to receive status info. It can also be used to + grab the stream at any point in the filter chain. para_audioc + is needed by para_gui, para_sdl_gui and para_krell, see below. + +- para_gui (optional, but recommended): + + Themable ncurses-based gui. It calls para_audioc and presents + the obtained information in an ncurses window. para_gui + provides key-bindings for the most common commands and new + key-bindings can be added easily. + +- para_sdl_gui (optional): + + SDL-based gui. Similar to para_gui but presents its output in + an X window (fullscreen mode is also available) and can display + jpg images on a per song basis. para_sdl_gui provides an input + prompt to enter arbitrary commands. However, it can also be used + non-interactively (e.g. as a screen saver) via the -i switch. + +- para_krell (optional, only useful in conjunction with the mysql dbtool): + + A plugin for gkrellm which shows small pictures of the + current song. It allows you to launch 27 different commands + by clicking in different areas of its picture (9 small squares + x 3 mouse buttons). + +- para_fade (optional): + + A (Linux-only) alarm clock and volume-fader. + +- para_dbadm (optional, only useful in conjunction with the mysql dbtool): + + Very simple curses-based frontend which uses libmenu. Useful + for quickly changing the attributes of the current song + (e.g. from para_gui as an external command). + +- para_slider (optional, only useful in conjunction with the mysql dbtool): + + A small X application which shows a scrollbar for each + attribute defined in the mysql database. It creates a stream + definition from the values of the scrollbars. This allows + to smoothly change the mood of the given stream without any + file editing. + +- bash_completion (optional): + + A small bash script for inclusion in ~/.bashrc. It gives you + command line completion for some paraslash commands. + +REQUIREMENTS: +~~~~~~~~~~~~~ +In any case you need + + - gcc, the gnu compiler collection (shipped with distro): gcc-3 + or newer is prefered, but gcc-2.95 is still supported. Note + that gcc-2.95 may spit out many warnings like unused function + parameters and missing initializers. These are all harmless + and may be ignored. + + - openssl (needed by server, client): usually shipped with + distro, but you might have to install the "development" + package as well + + http://www.openssl.org/ + + - software mixing, e.g. ALSA and the direct mixing plugin (dmix) + +If you want to use the mysql-based dbtool (recommended), you also need + + - mysql-server + - mysql-client + - libmysqlclient + +These are usually shipped with the distro but probably not installed +by default. + +The mp3 decoder of para_filter is based on libmad: + + http://www.underbit.com/products/mad/ + +If you prefer to use the libmad package provided by your distributor, +make sure to install the corresponding development package as well. + +If you want to stream ogg vorbis files you'll need: + + - libogg, libvorbis, libvorbisfile, and a command line ogg vorbis + player, e.g. para_filter or ogg123. + + http://www.xiph.org/downloads/ + +Note that para_audiod still works even if neither mp3 nor ogg support +was compiled in. You'll have to use the --no_default_filters option +in this case (and e.g. "mpg123 -" as the stream write command). + +If you intend to use the optional ortp streamer: + + - libortp + + http://www.linphone.org/ortp/ + + +For the optional SDL-based gui, the following packages must be installed: + + - X (usually shipped with distro) + + http://www.x.org/ + + - libSDL (usually shipped with distro) + + http://www.libsdl.org/index.php + + - SDL_image + + http://www.libsdl.org/projects/SDL_image/ + +For para_slider, the zero memory widget library is neccessary. Get it at + + http://www710.univ-lyon1.fr/~exco/ZMW/ + +Finally, para_krell needs + + - gtk2 + + http://www.gtk.org/ + + - gkrellm2 + + http://members.dslextreme.com/users/billw/gkrellm/gkrellm.html + +LICENSE: +~~~~~~~~ +Distribution of paraslash is covered by the GNU GPL.

You may either specify these options +in ~/.paraslash/server.conf or directly at the command line (not +recommended for passwd option). Don't forget to do + + chmod 600 ~/.paraslash/server.conf + +as this file contains the mysql passwd. To make these changes take +effect you'll need to do + + para_client hup + +Or, restart the server. + +Switch to the mysql dbtool +~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Actually, the mysql database tool should already be selected (just +ignore the warning about the missing database). To verify that it is +indeed activated, type + + para_client cdt + +which prints the name of the current database tool. If the dopey +dbtool is still selected, try + + para_client cdt mysql + +If this doesn't work either, it means that some required config options +were not specified (check the log for more info) or that para_server +was built without mysql support. Type + + para_client si + +to find out. If mysql is not mentioned as a supported database tool, +you'll have to recompile. + + +Create a new database +~~~~~~~~~~~~~~~~~~~~~ + +Once the mysql database tool is selected, create the database: + + para_client cdb + para_client cdt mysql + +The second command forces para_server to re-init the mysql dbtool. +Check the log. There should not be any warnings or errors. + + +Fill your database with content +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + + para_client upd + +If this command fails, it most likely means the audio file directory +(given in the server configuration file) does not exist, is empty, +not readable, or contains different files with identical basenames. Fix +this problem before proceeding. + +The command + + para_client ls + +prints the list of all files known by the mysql dbtool. If the list +is empty, double check the mysql_audio_file_dir option. + + +Create a stream which selects all songs +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +To keep it simple, let's only define the stream "all_songs". See below for +advanced stream usage. + + para_client stradd all_songs < /dev/null + para_client sl 10 all_songs + +The latter command should show you ten filenames. + + +Change to the all_songs stream +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + + para_client cs all_songs + +You should now be able to start streaming with + + para_client play + + +Attribute usage +~~~~~~~~~~~~~~~ + +An attribute is simply a bit which can be set for each sound file +individually. You may have as many attributes as you like. A new +attribute "test" is created by + + para_client na test + +and + para_client laa + +lists all available attributes. You can set the "test" attribute for +the current song by executing + + para_client sa test+ + +or for any particular song by + + para_client sa test+ filename + +You can unset the attribute "test" for the current song with + + para_client sa test- + +and you can drop the test attribute entirely from the database with + + para_client da test + +Stream usage +~~~~~~~~~~~~ + +A stream is a pair of expressions in terms of attributes and other +meta data contained in the database. The first, boolian, expression +determines the set of songs which are permitted in this stream. The +second, integer, expression determines the order in which permitted +songs are going to be fed to the audio file sender(s). + +To create a new stream called "my_stream", put arbitrary many (including +none) accept or deny lines and one or zero score lines into some +temporary file, say tmpfile. An accept/deny/score line consists of +an identifier ("accept:", "deny:", or "score:"), followed by an +expression. The command + + para_client stradd my_stream < tmpfile + +adds the stream "my_stream" to dbtool's stream database. + +If the stream definition is really short, you may also just pipe it to +the client rather than using temporary files. Like this: + + echo "$MYSTREAMDEF" | para_client stradd my_stream + + +Example: + + Assume you already have an attribute "test" and you'd like to + to restrict the set of songs being played to those having the + "test" attribute set. Define a new stream "only_test" by + + echo 'accept: IS_SET(test)' | para_client stradd only_test + + Then, after switching to the "only_test" stream with + + para_client cs only_test + + only the desired songs are going to be played. + +There is no need to keep the temporary files containing the stream +definition since you can always query the database to get it back: + + para_client strq only_test + +The accept/deny expressions are used to find out which songs are +permitted. The following four cases are all possible and valid: + + o Neither accept nor deny lines: This selects all songs. + + o Only accept lines: Songs that match at least one accept + expression are accepted, all others are denied: + + accept_expr1 or accept_expr2 or ... + + o Only deny lines: Songs that match at least one deny expression are + denied, all others are accepted: + + not (deny_expr1 or deny_expr2 ...) + + o Both accept and deny lines: A song is accepted if it matches + at least one accept expression, but no deny expression, i.e. + + (accept_expr1 or accept_expr2 or ..) and not + (deny_expr1 or deny_expr2 ..) + +The command + + para_client streams + +lists all available streams and + + para_client strdel streamname + +removes the stream "streamname". + +There are more sophisticated ways to define a stream than just using +one IS_SET() macro as in the example above. Of course, IS_SET(foo) +is true for a given audio file if and only if it has the attribute +"foo" set. Here are some more macros you can use: + + o IS_N_SET(attr): True if attribute attr is not set + + o NAME_LIKE(string): True if basename is like (in the sense + of mysql) "string" + + o LASTPLAYED(): Expands to number of minutes that are gone + since this audio file has been played (by paraslash). + + o NUMPLAYED(): Expands to number of times, the file has + been played. + + o PICID(): Expands to the number of the picture which is + associated with this song. + +To give a real-life example, suppose you have already added the +attributes "pop", "rock" with the "na" command. Assume also that you +have set these attributes for some or all of your songs having the +corresponding properties. + +If you like to be waked up in the morning by poprock songs, but you +have some strange feeling telling you that just a few seconds of +Madonna's voice will be enough to mess up your whole day, just write +the lines + + accept: IS_SET(pop) and IS_SET(rock) + deny: NAME_LIKE(%Madonna%) + +to some temporary file "tmp" and do + + para_client stradd wake < tmp + +You can then switch to the new stream with + + para_client cs wake + +or you can let cron do this for you on a daily basis.. + +Accept/deny lines affect only the set of admissible songs, but not +the order in which these songs are played. That's where the score +expression comes into play. + +Scoring +~~~~~~~ +You may put a single score line anywhere in the stream definition. If +omitted, the default scoring rule specified in the configuration file +applies. If there is no default scoring rule in the config file either, +the compiled in default is going to be used (see para_server -h). + +Simple examples of scoring rules (either specified in a stream +definition or as the default scoring rule in the config file) include: + + LASTPLAYED()/1440 + +This means that each song's score is just the number of days that went +by since this song has been played (one day is 1440 minutes). This +is fine in many cases since the dbtool then always chooses that +admissible song, which wasn't played for the longest time. + +However, one disadvantage of this scoring sheme is that new songs, +once played, are going to be deferred for a possibly very long period +depending on the size of your collection of (admissible) songs. Hence +the following scoring rule comes into mind: + + score: -NUMPLAYED() + +since this gives newer songs, i.e. songs to which you haven't listen to +that often, a higher score than older songs you already know by heart. + +You can also use a combination of these two methods: + + score: LASTPLAYED()/1440 - 10 * NUMPLAYED() + +which subtracts 10 score points for each time paraslash has played +this song. + +Another useful feature for scoring is due to the fact that "true" +expands to one and "false" to zero. So you can also use the +IS_SET/IS_N_SET/NAME_LIKE macros in a score line to give +your favorite band "bar" some extra points: + + score: 40 * IS_SET(foo) + 20 * NAME_LIKE(%bar%) + LASTPLAYED()/1440 + + +Pictures +~~~~~~~~ + +dbtool can also magage images that, when associated with certain songs, +can be displayed by para_sdl_gui and para_krell when one of these songs +is playing. It is also possible to just retrieve the current image via + + para_client pic > filename + +in order to feed it to your favorite tool. Try + + para_client help | grep ^pic + +and read the online help of the shown commands for more information. diff --git a/SFont.c b/SFont.c new file mode 100644 index 00000000..407ef990 --- /dev/null +++ b/SFont.c @@ -0,0 +1,259 @@ +/* + * Copyright (C) Karl Bartel WWW: http://www.linux-games.com + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation; either version 2 of the License, or + * (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

+ Everybody loves screenshots, so + here + we go. +
+ +

Download

+ +

Only source is available, + including the + nightly cvs snapshot. All regular releases are + cryptographically signed. + Anonymous (read-only) cvs access is also + available. Checkout a copy with

+ +

cvs -d + :pserver:anonymous@cvs.systemlinux.org:/var/lib/cvs + login

+

(empty passwd)

+

cvs -d :pserver:anonymous@cvs.systemlinux.org:/var/lib/cvs co paraslash

+ + +

Finally, you can RTFS online. +

+ +

Live Demo

+ +

There is a public paraslash stream at www.paraslash.org, + streaming + + the music of Henri Petterson. + + + You can listen to the stream with any mp3 player that supports + http streaming. Both

+ +

mpg123 http://www.paraslash.org:8009/

+ + and + +

xmms http://www.paraslash.org:8009/

+ +

are known to work.

+ +

Moreover, there is an anonymous paraslash account + available which you can use to have a look at paraslash + without configuring and running para_server on your own box. + Just download and run + + this shell script + + on your Unix system. If you prefer to do things manually, + simply cut-and-paste the instructions given below verbatim + to your shell. No root-privileges are required.

+ +
    +
  • + Check that both aplay and mpg123 are installed on your system +
    • + +
  • + Download + a recent paraslash package. You + you need paraslash-0.2.0 or later + for the demo, paraslash-0.1.x will not work. +
    • + +
  • + + Install the neccessary paraslash binaries + (you can safely ignore any warnings about + missing software): + +
      +
    • tar xjf paraslash-cvs.tar.bz2
      • +
    • cd paraslash-cvs
      • +
    • bin="para_client para_audioc para_audiod para_gui" # all we need +
    • (./configure --prefix="$HOME" && make $bin) > /dev/null
      • +
    • mkdir -p $HOME/bin; cp $bin $HOME/bin +
    • export PATH=$HOME/bin:$PATH + +
    + There should be no errors. +
    • +
  • + Get the key for the anonymous account on + www.paraslash.org: + +
      +
    • dir="$HOME/.paraslash"; server=www.paraslash.org
      • +
    • mkdir -p $dir
      • +
    • wget --directory-prefix=$dir http://$server/key.anonymous
      • +
    +
    • +
  • + Tell para_client that we want to connect to + www.paraslash.org as user anonymous: + +
      +
    • conf="$dir/client.conf"; socket="$dir/socket"
      • +
    • echo user \"anonymous\" > $conf
      • +
    • echo hostname \"$server\" >> $conf
      • +
    • echo key_file \"$dir/key.anonymous\" >> $conf
      • +
    • echo socket \"$socket\" >> $dir/audioc.conf
      • +
    +
    • +
  • + Start para_audiod +
    • + + para_audiod -d --stream_read_cmd + "mp3:mpg123 -s http://$server:8009/" + --stream_write_cmd "mp3:aplay -fcd" -L $dir/audiod.log + --socket=$socket + +
    +

Live Demo

There is a public paraslash stream at www.paraslash.org, + streaming + + the music of Henri Petterson. + + + You can listen to the stream with any mp3 player that supports + http streaming. Both

+ +

mpg123 -Z http://www.paraslash.org:8009/

+ + and + +

xmms http://www.paraslash.org:8009/

+ +

are known to work.

+ +

Moreover, there is an anonymous paraslash account + available which you can use to have a look at paraslash + without configuring and running para_server on your own box. + Just download and run + + this shell script + + on your Unix system. No root-privileges are required.

Documentation

+

+Have a look at this + overview, +a pdf file containing a sketch which illustrates how the pieces of paraslash work +together. Read + README +for general information (including a list of required software), + INSTALL +for installation notes, and + README.mysql +for instructions on how to use the mysql database tool +shipped with paraslash.

+

+The various commands of para_server and para_audiod are explained in +paraslash's + manual pages. +

+

+As of version 0.2.10, the source of para_server and para_audiod is fully documented. +Have a look at the + Paraslash API Reference. +

+

Finally, you can RTFS online. +

Screenshots

+ +

The main part of paraslash is a client-server application, so +it doesn't have much to take a screenshot of. However, here is the +startup part of + + para_server's logfile + +and a similar thing for the logfile of + + para_audiod.

+ +Moreover, there are screenshots of + + para_gui, + + para_sdl_gui, + + para_krell + +and + para_slider. +
