.. warning:: Unstable
This function is unstable, API may change without warning.
It will also raise unless use in proper context manager.
Parameters
----------
text:str
Full text of the current input, multi line string.
offset:int
Integer representing the position of the cursor in ``text``. Offset
is 0-based indexed.
Yields
------
:any:`Completion` object
The cursor on a text can either be seen as being "in between"
characters or "On" a character depending on the interface visible to
the user. For consistency the cursor being on "in between" characters X
and Y is equivalent to the cursor being "on" character Y, that is to say
the character the cursor is on is considered as being after the cursor.
Combining characters may span more that one position in the
text.
.. note::
If ``IPCompleter.debug`` is :any:`True` will yield a ``--jedi/ipython--``
fake Completion token to distinguish completion returned by Jedi
and usual yap_ipython completion.
.. note::
Completions are not completely deduplicated yet. If identical
completions are coming from different sources this function does not
ensure that each completion object will only be present once.

/** @pred 0:Condition -> 0:Action is iso
@short If _Condition__ has a solution, call _Action_;

Read as "if-then-else" or "commit". This operator is similar to the
conditional operator of imperative languages and can be used alone or
with an else part as follows:
~~~~~
+P -> +Q
~~~~~
"if P then Q".
~~~~~
+P -> +Q; +R
~~~~~
"if P then Q else R".
These two predicates could be defined respectively in Prolog as:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
(P -> Q) :- P, !, Q.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
and
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
(P -> Q; R) :- P, !, Q.
(P -> Q; R) :- R.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
if there were no "cuts" in _P_, _Q_ and _R_.
vNote that the commit operator works by "cutting" any alternative
solutions of _P_.
Note also that you can use chains of commit operators like:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
P -> Q ; R -> S ; T.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Note that `(->)/2` does not affect the scope of cuts in its
arguments.

Read as "cut". Cuts any choices taken in the current procedure.
When first found "cut" succeeds as a goal, but if backtracking should
later return to it, the parent goal (the one which matches the head of
the clause containing the "cut", causing the clause activation) will
fail. This is an extra-logical predicate and cannot be explained in
terms of the declarative semantics of Prolog.
example:

member(X,[X|_]).
member(X,[_|L]) :- member(X,L).

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
?- member(X,[1,2,3]).

the loop is effectively terminated by the cut-goal, when the test-goal
`X=end` succeeds. While the test fails, the goals `read(X)`,
`write(X)`, and `nl` are executed repeatedly, because
backtracking is caught by the `repeat` goal.
The built-in `repeat/0` could be defined in Prolog by:

/** @pred exception(+ _Exception_, + _Context_, - _Action_)
Dynamic predicate, normally not defined. Called by the Prolog system on run-time exceptions that can be repaired `just-in-time`. The values for _Exception_ are described below. See also catch/3 and throw/1.
If this hook predicate succeeds it must instantiate the _Action_ argument to the atom `fail` to make the operation fail silently, `retry` to tell Prolog to retry the operation or `error` to make the system generate an exception. The action `retry` only makes sense if this hook modified the environment such that the operation can now succeed without error.
+ `undefined_predicate`
_Context_ is instantiated to a predicate-indicator ( _Module:Name/Arity_). If the predicate fails Prolog will generate an existence_error exception. The hook is intended to implement alternatives to the SWI built-in autoloader, such as autoloading code from a database. Do not use this hook to suppress existence errors on predicates. See also `unknown`.
+ `undefined_global_variable`
_Context_ is instantiated to the name of the missing global variable. The hook must call nb_setval/2 or b_setval/2 before returning with the action retry.
