In addition to the document text passed via standard input,
shell scripts have a number of environment variables set. $APP_PID
variable is set to the current process process id, so that opening a file in the
same instance of medit is as simple as medit filename
(on the other
hand, you will have to use command line options if you need to run a new medit instance).
The following environment variables are set when scripts are executed:
DOC |
the document basename. |
DOC_DIR |
the document file directory. The full file path is $DOC_DIR/$DOC . |
DOC_BASE |
the basename without extension. |
DOC_EXT |
the document filename extension including the period. The basename is always $DOC_BASE$DOC_EXT . |
LINE |
the number of the line containing cursor. |
DATA_DIR |
the user data directory. For example the tools are stored in $DATA_DIR/menu.cfg file and in files in the $DATA_DIR/tools/ directory. |
Additionally, all processes ran from inside medit will have DATADIR/scripts
directories in $PATH
, so you may place some medit-specific programs
or scripts into USERDATADIR/scripts/
to be used from shell script tools.
