| Ensure Global Variable
| | [Documentation] | Give default value (from environment or code) to variable.
| | ...
| | ... | Ideally we would just use Variables table to set global variables.
| | ... | Unfortunately, __init__ files are special (among other things)
| | ... | by the fact that variables set in the table are not available
| | ... | for (sub)directory suites.
| | ... | Therefore we are using BuiltIn.Set_Global_Variable explicitly.
| | ... | While we are running code here, we allow environment variables
| | ... | to override the default values.
| | ... | If environment variable name is not specified (or empty),
| | ... | the upper case of the variable name is used, prefixed by "CSIT_".
| | ... | The --variable parameter to pybot takes precedence to environment.
| | ...
| | ... | *Arguments:*
| | ... | - variable_name - Name of global variable to set. Type: string
| | ... | - default_value - Value to set if not set otherwise. Type: string
| | ... | - env_var_name - Name of environment variable to read. Type: string
| | ... | - application - Prefix for default environment variable. Type: string
| | ...
| | ... | *Example:*
| | ... | \| Ensure Global Variable \| perf_trial_duration \| 10.0 \| TRIAL_DUR
| | ...
| | [Arguments] | ${variable_name} | ${default_value} | ${env_var_name}=${EMPTY}
| | ... | ${application}=CSIT
| | ...
| | ${env_var_length} = | Get Length | ${env_var_name}
| | ${default_env_var} = | Convert To Uppercase | ${variable_name}
| | ${env_var} = | Set Variable If | ${env_var_length}
| | ... | ${env_var_name} | ${application}_${default_env_var}
| | ${updated_default} = | Get Environment Variable
| | ... | ${env_var} | ${default_value}
| | ${final_value} = | Get Variable Value
| | ... | \${${variable_name}} | ${updated_default}
| | Set Global Variable | \${${variable_name}} | ${final_value}
