When using iPython as the inferior shell of python.el, =
`python-shell-completion-at-point' skips a `simple-operator=E2=80=99 =
regexp which include ?%. In iPython, magic commands begin with =E2=80=98%=
=E2=80=99, and the fallback completion method happily provides them for =
completion:
In [67]: __PYTHON_EL_get_completions("%ru")
Out[91]: ['%%ruby', '%run=E2=80=99]
python-shell-completion-at-point trims this to =E2=80=9Cru=E2=80=9D, =
which also provides the same completions above, but which =
`try-completions=E2=80=99 rejects as non-matching. So that:
In [1]: %ru[Tab]
Leads to =E2=80=9CNo matches=E2=80=9D.
The solution would be to not skip the ?% character if it is at the start =
of the line. The modulo operator cannot occur there in any case.=20
One other point: the fallback mechanism sends and compiles the =
relatively long __PYTHON_EL_get_completions function each and every time =
it is called. Because of how CAPF functions, this actually occurs 3 =
times in quick succession with a single Tab press like the above! A =
more performant approach (esp. over remote buffer connections) would be =
to just call __PYTHON_EL_get_completions, and check for failure, setting =
up that function again if necessary. This would parallel the readline =
completer native method, which is only setup once.=20
