Make this scriptfile executible
by issuing
chmod +x assoc.py
and include the path to assoc.py to the PATH environment string.
To use, type
assoc.py flag filename extra_args
where flag may be absent (default would then be -v) or takes on the
following suggested values in the table.
flag action
-----------------------
view
-v view
-e edit
-c compile
-r run or execute
-p print
-----------------------
Example:
assoc.py -e test.c
should fire-up emacs.
assoc.py -D
will dump the dictionary.
The optional extra_args allows you to add additional settings to the
command associated with the file extension. More complicated
actions may require Python functions instead of simple strings as dictionary
values.
