Tab completion

Tab completion is implemented to prevent insanity as the function names can be quite long - a deliberate feature to improve usability. The behaviour of the tab completion is very similar to that of the bash prompt.

Not only is tab completion useful for preventing RSI but it can also be used for listing all available functions. To begin with if you hit the [TAB] key without typing any text all available functions will be listed (along with function classes and other python objects). This extends to the exploration of user functions within a function class. For example to list the user functions within the function class model_free type

[numbers=none]
relax> model_free.

The dot character at the end is essential. After hitting the [TAB] key you should see something like

[numbers=none]
relax| model_free.
model_free.__class__
model_free.__doc__
model_free.__init__
model_free.__module__
model_free.__relax__
model_free.__relax_help__
model_free.create_model
model_free.delete
model_free.remove_tm
model_free.select_model
relax> model_free.

All the objects beginning with an underscore are “hidden”, they contain information about the function class and should be ignored. From the listing the user functions copy, create_model, delete, remove_tm, and select_model contained within model_free are all visible.
