Strings (mostly file names), 14 #. Scalars (a number representing a physical quantify, usually with units), 15 #. Integers (an integer number, usually corresponding to a count), 16 #. Flags (True/False, on/off, yes/no), 17 #. Keywords (one of a given set of strings). 18 19 Each parameter can be set using the command-line option consisting of a dash followed by 20 the parameter name. For example, 21 22 .. code-block:: none 23 24 -constants.standard_gravity 10 25 26 sets the acceleration due to gravity (parameter :config:`constants.standard_gravity`) to 27 `10`. Options listed below are *shortcuts*, added for convenience. 28 29 The following are equivalent and choose the temperature-based (as opposed to 30 enthalpy-based) energy balance model: 31 32 .. code-block:: none 33 34 -energy.temperature_based 35 -energy.temperature_based on 36 -energy.temperature_based yes 37 -energy.temperature_based true 38 -energy.temperature_based True 39 40 The following are also equivalent: they disable updating geometry by performing a step of 41 the mass-continuity equation: 42 43 .. code-block:: none 44 45 -geometry.update.enabled off 46 -geometry.update.enabled no 47 -geometry.update.enabled false 48 -geometry.update.enabled False 49 -no_geometry.update.enabled 50 51 The ``-no_`` prefix is still supported for compatibility with older scripts, but will be 52 removed in a later PISM version. 53 54 .. include:: parameter-list.txt
