dtsdlfile special file dtsdlfile CDE runtime help volume files Semantic Delivery Language (sdl) files are used for presenting online information or application specific contextual help information in CDE. They are refered to as Help Volumes, and contain the equivalent of a runtime version of the original, authored help information. Help Volumes can be viewed via one of the two CDE help dialog widgets provided as part of the CDE Development Environment. Refer to the &cdeman.dthelptag; man page for detailed information on the creation of *.sdl files within CDE. The CDE Help system uses two environment variables for locating Help volumes and Family files within the desktop environment: DTHELPSEARCHPATH System search path environment variable for locating Help volumes on local and/or remote nfs mounted systems. DTHELPUSERSEARCHPATH Users search path environment variable for locating user specific Help volumes on local and/or remote nfs mounted systems. The environment variables contain colon-separated lists of directory paths. Each directory path can contain environment variable names as well as special field descriptors that are expanded at runtime. Field descriptors consist of a % followed by a single character. Field descriptors and their substitution values are: %H This value is replaced with the current volume or Family name being searched for. %L Replaced with the current value of the LANG environment variable. %% Replaced with a single %. The default value for DTHELPUSERSEARCHPATH is: $HOME/.dt/help/$DTUSERSESSION/%H:$HOME/.dt/help/$DTUSERSESSION/%H.sdl:$HOME/.dt/help/$DTUSERSESSION/%H.hv:$HOME/.dt/help/%H:$HOME/.dt/help/%H.sdl:$HOME/.dt/help/%H.hv The DTHELPUSERSEARCH is first searched for the requested volume. If the volume is not found, the DTHELPSEARCHPATH value is searched. The default value for DTHELPSEARCHPATH path is: /etc/dt/appconfig/help/%L/%H:/etc/dt/appconfig/help/%L/%H.sdl:/etc/dt/appconfig/help/%L/%H.hv:/etc/dt/appconfig/help/C/%H:/etc/dt/appconfig/help/C/%H.sdl:/etc/dt/appconfig/help/C/%H.hv:/usr/dt/appconfig/help/%L/%H:/usr/dt/appconfig/help/%L/%H.sdl:/usr/dt/appconfig/help/%L/%H.hv:/usr/dt/appconfig/help/C/%H:/usr/dt/appconfig/help/C/%H.sdl:/usr/dt/appconfig/help/C/%H.hv &cdeman.DtCreateHelpDialog;, &cdeman.DtCreateHelpQuickDialog;, &cdeman.dthelptag;, CDE Help System Author's and Programmer's Guide
