documentation for operator... Stefan Schuermans authored 12 years ago	49) <h2>Operator Connections</h2> 50) <p> 51) Some modules can react to events and/or send events to other modules. 52) Suche events are delivered over so-called operator connections. 53) A module can caonnect to another module listen for incoming operator 54) connections. 55) If this connection is accepted, both modules can exchange events over 56) the connection until one of the modules choses to close the connection. 57) <br> 58) In the context of controlling Blinkenlights style displays over a phone 59) connections, events can be keys pressed on the phone or requests to play 60) a certain sound. 61) </p>
start page of documentation Stefan Schuermans authored 12 years ago	62) <h2>Configuration Directory</h2> 63) <p> 64) The configuration of blinker is not stored in a single file, but in a 65) directory structure, reflecting the inner structure of Blinker's 66) modules. 67) This way, every module has got its own configuration directory 68) containing single files each containing one simple setting. 69) It the module has some internel structure, those config setting 70) files are organized in a directory structure underneath the module's 71) configuration directory. 72) </p> 73) <p> 74) The main config directory contains a directory for each module 75) class, e.g. <code>players</code> for movie player modules. 76) Inside, there is an arbitrary number of subdirectories, one 77) for each instantance of the player module. 78) E.g. the <code>players/stereoscope</code> directory in the example 79) configuration (<code>example_cfg</code> directory in the top level) 80) contains the configuration of the movie player for Blinkenlights 81) stereoscope movies. 82) </p> 83) <p> 84) Reconfiguration can happen at runtime by just changing the configuration 85) directory. 86) Blinker will detect those changes and adapt its operation to the new 87) configuration without restart. 88) <br> 89) Sometimes, especially after an invalid configuration has been seen by 90) Blinker, changes are not automatically detected by Blinker. 91) In this case, it is neccessary to <code>touch</code> the parent 92) directory containing the setting file to make Blinker aware of 93) the reconfiguration. 94) (Solving this issue is planned.) 95) </p> 96) <h2>Modules</h2> 97) <p> 98) The following module types are available for instantiation: 99) <ul>
