New submission from Martin Panter:
As mentioned in Issue 25209, here is a patch to complete module and attribute
names in import statements. This is a rewrite of some personal code I have had
kicking around for a few years, but I have added extra features (parsing
“import x as alias”, supporting “from .relative import x”).
All the existing completions should continue to work as long as the statement
immediately preceding the cursor does not look like an “import” statement. When
an import statement is detected, these other completions are disabled.
When alternative completions are displayed, my code appends a dot (.) indicator
to package names, but this is not inserted in the input line. Maybe people
think this is a good idea or maybe not.
This illustrates what it looks like in action. Text in square brackets was
automatically completed:
Python 3.6.0a0 (qbase qtip readline/complete-import.patch tip:65d2b721034a, Oct
16 2015, 10:02:3)
[GCC 5.1.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import io, h<Tab><Tab>
hashlib heapq hmac html. http.
>>> import io, htm[l].<Tab><Tab>
html.entities html.parser
>>> import io, html.e[ntities]
>>> from html import e<Tab><Tab>
entities escape
>>> from html import es[cape]
The code works around Issue 16182 (byte vs code point indexing) in a very
simplistic way. It probably won’t give useful completions (if any) for
non-ASCII input involving imports.
The patch currently does not complete built-in module names
(sys.builtin_module_names). This should not be hard to add, but I need to
decide whether the support should be added specially in rlcompleter, or
generally in pkgutil.iter_modules() instead.
I also have code to complete the following, which I could try to make patches
for if there is interest:
* keyword argument names to function calls, e.g. open("file", enc[oding=]
* attributes on constructor return types, e.g. ValueError("msg").__t[raceback__]
