Explaining what datastore funcs. do when a variable does not exist Hello Scott, Here's some suggested additions to '3.11.1. Functions for Accessing Datastore Variables' to explain what happens when the variable does not exist: * Add this to the d.getVar() description: Returns None if the variable "X" does not exist. * Add this to the d.appendVar() description: Acts like d.setVar("X", "value") if the variable "X" does not exist. * Add this to the d.prependVar() description (same as above): Acts like d.setVar("X", "value") if the variable "X" does not exist. * Add this to the d.delVar() description: Does nothing if the variable "X" does not exist. * Add this to the d.renameVar() description: Does nothing if the variable "X" does not exist. * Add this to the d.getVarFlag() description: Returns None if either the variable "X" or the named flag does not exist. * Add this to the d.appendVarFlag() description: Acts like d.setVarFlag("X", flag, "value") if the named flag does not exist. * Add this to the d.prependVarFlag() description (same as above): Acts like d.setVarFlag("X", flag, "value") if the named flag does not exist. * Add this to the d.getVarFlags() description: Returns None if the variable "X" does not exist. * Add this to the d.delVarFlags() description: Does nothing if the variable "X" does not exist. * Add this to the d.expand() description: References to variables that do not exist are left as is. For example, d.expand("foo ${X}") expands to the literal string "foo ${X}" if the variable "X" does not exist. Cheers, Ulf
