Slavek: Request help revising starttde

Slavek, As I mentioned in previous posts, the current mechanism in starttde causes $TDEDIRS to be ignored when $XDG_DATA_DIRS is explicitly defined in the environment. I know what we need to do, but my regex skills are much to be desired. You helped with the last revision and probably can help again. :) This is what we need to add to the existing snippet regarding $XDG_DATA_DIRS: * When $TDEDIRS is not defined in the environment, do nothing additional. Leave functionality as is. * When $TDEDIRS is defined then parse that variable into separate directories. Use those separate directories to form the $XDG_DATA_DIRS variable. Notes: Explicitly declaring $XDG_DATA_DIRS will override $TDEDIRS, which must then be explicitly identified in the $XDG_DATA_DIRS string to remain useful. When $XDG_DATA_DIRS is not explicitly declared, then $TDEDIRS is recognized and works as intended. Therefore we need to compensate when explicitly declaring $XDG_DATA_DIRS. The $TDEDIR variable is intended to be singular and $TDEDIRS plural. When $TDEDIRS exists in the environment then parse that variable into separate directories. By design, $TDEDIRS should contain whatever is set in $TDEDIR. Therefore any additional directories set in $TDEDIRS are intended to override data files found in $TDEDIR. In both $TDEDIRS and $XDG_DATA_DIRS, those additional directories should be placed before $TDEDIR and before /usr/share. In $XDG_DATA_DIRS, $TDEDIR should be placed before /usr/share to ensure those data files override anything in /usr/share. For example, on my system I have the following: $TDEDIR=/opt/trinity $TDEDIRS=/usr/local/tde-mods:/opt/trinity Therefore in my system, $XDG_DATA_DIRS should look like this: XDG_DATA_DIRS=/usr/local/tde-mods/share:/opt/trinity/share:/usr/share I know of no limitations for expanding $TDEDIRS. Theoretically then, $TDEDIRS could contain more than two directories, but the last directory in the $TDEDIRS variable should always be what is defined in $TDEDIR. For example, the following presumably could exist: $TDEDIR=/opt/trinity $TDEDIRS=/usr/local/tde-mods:/opt/tde-mods:/opt/trinity Therefore $XDG_DATA_DIRS would look like this: XDG_DATA_DIRS=/usr/local/tde-mods/share:/opt/tde-mods/share:/opt/trinity/share:/usr/share I appreciate any help. Of course, I will test as much as possible. Thank you! Darrell
