Hi,
Currently python-shell-completion-at-point doesn't respect the
delimiter setting of readline completer and always split the text,
resulting in poor completions when completers that don't need word
splitting, e.g. jedi[1], is used. This patch fixes the problem.
Meanwhile, this patch adds an option 'python-shell-readline-completer'
to make Python shell provide better completion experience (e.g.
completing function parameters, dictionary keys) by default if users
are using vanilla Python interpreter with jedi or using IPython, where
the completion support for IPython has been enhanced (e.g. showing
type annotations and function signatures).
BTW, I think it may make sense to move Python snippets to a separate
file to make them easier to be maintained.
Thanks.
Best,

Subject: [PATCH] Improve Python shell completion
* lisp/progmodes/python.el (python-shell-completion-setup-code): Fix
the completion code of IPython. Change the return value to JSON
string and ...
(python-shell-completion-get-completions): ... simplify parsing.
(inferior-python-mode): Update docstring.
(python-shell-readline-completer): New option.
(python-shell-readline-completer-delims)
(python-shell-readline-jedi-setup-code)
(python-shell-readline-ipython-setup-code): New variables.
(python-shell-completion-native-setup): Setup a suitable readline
completer and set the completer delimiter.
(python-shell-completion-native-get-completions): Convert output
string to completions properly.
(python-shell-completion-at-point): Send text beginning from the line
start if the completion backend does not need word splitting. Remove
the detection of import statement because it is not needed anymore.
Create proper completion table based on completions returned from
different backends.
* test/lisp/progmodes/python-tests.el (python-shell-completion-module):
(python-shell-completion-parameters):
(python-shell-completion-at-point-jedi-completer):
(python-shell-completion-at-point-ipython): New tests.
* etc/NEWS: Announce the change.

Thanks. Let's see what others think about this (I don't use Python
enough to have an opinion that matters).

Thanks for the patch. I have tried it and found it to be a very
powerful enhancement.
Is it possible to allow completion of keyword arguments in a
multi-line function call like the following?
#+begin_src python
re.split(
'b',
'abc',
maxs
#+end_src
I am not sure if Python snippets should be separated. Do other
language supports keep them separate?

I think it allows to reduce code duplication (e.g. the IPython support
code existing in both python-shell-completion-setup-code and
python-shell-readline-ipython-setup-code) and make code more simple.
It seems other languages do not contain as many code snippets as
python.el.

Subject: [PATCH] Improve Python shell completion
* lisp/progmodes/python.el (python-shell-completion-setup-code): Fix
the completion code of IPython. Change the return value to JSON
string and ...
(python-shell-completion-get-completions): ... simplify parsing.
(inferior-python-mode): Update docstring.
(python-shell-readline-completer): New option.
(python-shell-readline-completer-delims)
(python-shell-readline-jedi-setup-code)
(python-shell-readline-ipython-setup-code): New variables.
(python-shell-completion-native-setup): Setup a suitable readline
completer and set the completer delimiter.
(python-shell-completion-native-get-completions): Convert output
string to completions properly.
(python-shell--get-multiline-input):
(python-shell--extra-completion-context): New functions.
(python-shell-completion-at-point): Send text beginning from the line
start if the completion backend does not need word splitting. Remove
the detection of import statement because it is not needed anymore.
Create proper completion table based on completions returned from
different backends.
* test/lisp/progmodes/python-tests.el (python-shell-completion-module):
(python-shell-completion-parameters):
(python-shell-completion-multi-line-function-call): New functions.
(python-shell-completion-at-point-jedi-completer):
(python-shell-completion-at-point-ipython): New tests.
* etc/NEWS: Announce the change.

Thank you. I tried the new patch and confirmed that the Python Shell
buffer allows keyword argument completion on multi-line function
calls. However, my expectation is that it can be done in Python
buffer as well (after calling `python-shell-send-buffer'). Is this
also possible?

Sorry, I misunderstood that snippets meant skeletons. I agree that
python.el has long Python codes, which is not easy to maintain. Are
you proposing to separate the snippets into .py file? If it's
acceptable from the Emacs' source code management perspective, I think
that is a good approach.

Thank you for the feedback. I have updated the patch to add support in
Python buffer.

Yes, I'd like to at least put some flags and functions shared by
python-shell-completion-native-setup and python-*-setup-code in a
separate .py file. On the other hand, they are not changed frequently,
so it is not in urgent need.

Subject: [PATCH] Improve Python shell completion (bug#68559)
* lisp/progmodes/python.el (python-shell-completion-setup-code): Fix
the completion code of IPython. Change the return value to JSON
string and ...
(python-shell-completion-get-completions): ... simplify parsing.
(inferior-python-mode): Update docstring.
(python-shell-readline-completer): New option.
(python-shell-readline-completer-delims)
(python-shell--readline-jedi-setup-code)
(python-shell--readline-ipython-setup-code): New variables.
(python-shell-completion-native-setup): Setup a suitable readline
completer and set the completer delimiter.
(python-shell-completion-native-get-completions): Convert output
string to completions properly.
(python-shell--get-multiline-input)
(python-shell--extra-completion-context)
(python-shell-completion-extra-context): New functions.
(python-shell-completion-at-point): Send text beginning from the line
start if the completion backend does not need word splitting. Remove
the detection of import statement because it is not needed anymore.
Create proper completion table based on completions returned from
different backends.
* test/lisp/progmodes/python-tests.el (python-tests--completion-module):
(python-tests--completion-parameters):
(python-tests--completion-extra-context): New helper functions.
(python-shell-completion-at-point-jedi-completer):
(python-shell-completion-at-point-ipython): New tests.
* etc/NEWS: Announce the change.

Thank you. It's working very nice.
I apologize for reporting in the piecemeal fashion, but I have noticed
the following differences from the current completion.
1. Module names cannot be completed in Python buffer.
2. Completion is not working in comments.
I'm not sure if the completion should work in comments, but some
people might want it because the current python-mode allows it in both
Python buffer and Python Shell buffer.

No worries. I appreciate your valuable feedback for improving the
quality of the patch.
> 1. Module names cannot be completed in Python buffer.
Can you elaborate? The completion of module names never worked for me
except using IPython with non-native completion mechanism.
Because module names cannot be completed using vanilla python
interpreter in the terminal, they are also not completed even with the
patch, unless jedi is available.

Thanks for pointing it out. The attached patch should now restore
previous basic completion behavior in comments.

Subject: [PATCH] Improve Python shell completion (bug#68559)
* lisp/progmodes/python.el (python-shell-completion-setup-code): Fix
the completion code of IPython. Change the return value to JSON
string and ...
(python-shell-completion-get-completions): ... simplify parsing.
(inferior-python-mode): Update docstring.
(python-shell-readline-completer): New option.
(python-shell-readline-completer-delims): New variable indicating the
word delimiters of readline completer.
(python-shell--readline-jedi-setup-code)
(python-shell--readline-ipython-setup-code): New internal variables.
(python-shell-completion-native-setup): Setup a suitable readline
completer and set the completer delimiter.
(python-shell-completion-native-get-completions): Convert output
string to completions properly.
(python-shell--get-multiline-input)
(python-shell--extra-completion-context)
(python-shell-completion-extra-context): New functions.
(python-shell-completion-at-point): Send text beginning from the line
start if the completion backend does not need word splitting. Remove
the detection of import statement because it is not needed anymore.
Create proper completion table based on completions returned from
different backends.
* test/lisp/progmodes/python-tests.el (python-tests--completion-module):
(python-tests--completion-parameters):
(python-tests--completion-extra-context): New helper functions.
(python-shell-completion-at-point-jedi-completer):
(python-shell-completion-at-point-ipython): New tests.
* etc/NEWS: Announce the change.

Hmm, I must have done something wrong. I cannot reproduce the problem
of module name completion even with the previous patch.
As for the current python-mode, I was able to complete the module
names because I enabled Jedi in PYTHONSTARTUP. Sorry for the confusion.
I'm experiencing strange behavior regarding completion of import
statement in a block in Python buffer. If I try to type the following
lines and then try to complete it, it will fail.
#+begin_src python
try:
im
#+end_src
However, when I try to complete at the beginning of the second line:
#+begin_src python
try:
#+end_src
"import" keyword also appears as a candidate. If I cancel the
candidates and type "im" and try to complete it, it will succeed.
This behavior does not occur in Python Shell buffer.
Another thing I noticed is the multi-line import statement. If the
import statement is one-line, each items (IGNORECASE and MULTILINE in
the example below) can be completed.
#+begin_src python
from re import IGNORECASE, MULTILINE
#+end_src
However, they cannot be completed if the import statement spans
multi-line.
#+begin_src python
from re import (
IGN
#+end_src
This happens in both Python buffer and Python Shell buffer. Perhaps
this is a limitation of Jedi completer?

Thanks, I confirmed that basic completion (without keyword argument
completion) can be performed within comments.

One additional comment regarding ERT. pyenv installs an ipython shim
to the shims directory, if there is at least one virtualenv providing
ipython. It can be found by `executable-find'. However, it is not
usable unless the virtualenv is activated. As a result, the
`python-shell-completion-at-point-ipython' ERT would fail unless a
virtualenv which provides ipython is activated.
This may be something pyenv users should take care of, but it is more
convenient for pyenv users like me to make the following changes.

Do we have a consensus about this issue? Should I install the
original patch, or are you still discussing it, and an updated patch
will be posted soon?
Thanks.

Although I think there are a few things left unanswered, the latest
patch sent on Jan 26th is very worthwhile and stable enough to be
installed. So, unless Liu is preparing a new patch, I agree that the
latest patch should be installed. That way more people can try it and
find the problem, if any.

Sorry for the late reply. Recent events have occupied all my time. I
plan to update the patch in the next day or two to address remaining
concerns.

The problem can be reproduced by running python with jedi completer in
a terminal. The reason is that readline completer can only see the
text in the current line, i.e. " im"; in this case, jedi does not
complete the text to " import".
Similarly, the jedi completer cannot complete "except" after ex:
try:
pass

It is because jedi produces completions including " import" for
blank string " ". Due to the same prefix between " " and
" im", completion cache is reused for the latter. Then " import"
can be completed.
It is more a limitation of readline completer than a problem with
jedi, as we cannot provide proper completion context for jedi. We may
define a custom completer to combine jedi and rlcompleter, e.g.
(setq python-shell-readline-completer "
def __PYTHON_EL_setup_readline_completer():
import readline, rlcompleter
import re, sys, os, __main__
from jedi import Interpreter
class MyJediRL:
def __init__(self):
self.rlcompleter = rlcompleter.Completer()
self.rldelim = readline.get_completer_delims()
def complete(self, text, state):
if state == 0:
sys.path.insert(0, os.getcwd())
try:
interpreter = Interpreter(text, [__main__.__dict__])
completions = interpreter.complete(fuzzy=False)
self.matches = [
text[:len(text) - c._like_name_length] + c.name_with_symbols
for c in completions
]
# try rlcompleter
sub = re.split('[' + re.escape(self.rldelim) + ']', text)[-1]
i = 0
while True:
completion = self.rlcompleter.complete(sub, i)
if not completion:
break
i += 1
completion = text[:len(text)-len(sub)] + completion.rstrip(' ()')
if completion not in self.matches:
self.matches.append(completion)
except:
raise
finally:
sys.path.pop(0)
try:
return self.matches[state]
except IndexError:
return None
readline.set_completer(MyJediRL().complete)
readline.set_completer_delims('')")

Yes. Because readline completer cannot see cross-line context, I added
the function "python-shell-completion-extra-context" in previous patch
to address the case of multi-line function call. I have updated the
attached patch to handle multi-line import statement.
The change to python-tests.el has been incorporated in the patch.
Thanks!

Thank you for the detailed explanation and the workaround. I
confirmed that the problem is solved by the above workaround. Just to
confirm, are you of the opinion that this workaround should not be the
default?

Thank you very much. I confirmed that the new patch allows completion
of multi-line import statements.

I'm not sure if we should add more Python code in the form of strings
to python.el, which increases maintenance burden IMO. Maybe they could
be distributed separately at ELPA/Git forges.
Actually, I'm considering simplifying this patch to mainly fix the bug
that python shell completion doesn't respect the delimiter of readline
completer. The new patch has been attached. It should support
the completer defined in the PYTHONSTARTUP file, e.g., jedi or a
custom completer like the above one. WDYT?

Subject: [PATCH] Respect the delimiter of completer in Python shell completion
* lisp/progmodes/python.el: (python-shell-completion-setup-code): Fix
the completion code of IPython. Change the return value to JSON string
and ...
(python-shell-completion-get-completions): ... simplify parsing.
(inferior-python-mode): Update docstring.
(python-shell-readline-completer-delims): New variable indicating the
word delimiters of readline completer.
(python-shell-completion-native-setup): Set the completer delimiter.
(python-shell-completion-native-get-completions): Convert output string
to completions properly.
(python-shell--get-multiline-input)
(python-shell--extra-completion-context)
(python-shell-completion-extra-context): New functions.
(python-shell-completion-at-point): Send text beginning from the line
start if the completion backend does not need word splitting. Remove
the detection of import statement because it is not needed anymore.
Create proper completion table based on completions returned from
different backends.
* test/lisp/progmodes/python-tests.el (python-tests--completion-module)
(python-tests--completion-parameters)
(python-tests--completion-extra-context): New helper functions.
(python-shell-completion-at-point-jedi-completer)
(python-shell-completion-at-point-ipython): New tests.
* etc/NEWS: Announce the change. (bug#68559)

I have updated documentation about readline completer and fixed an
error in commit log in the attach patch.

Subject: [PATCH] Respect the delimiter of completer in Python shell completion
* lisp/progmodes/python.el: (python-shell-completion-setup-code): Fix
the completion code of IPython. Change the return value to JSON string
and ...
(python-shell-completion-get-completions): ... simplify parsing.
(inferior-python-mode): Update docstring.
(python-shell-readline-completer-delims): New variable indicating the
word delimiters of readline completer.
(python-shell-completion-native-setup): Set the completer delimiter.
(python-shell-completion-native-get-completions): Convert output string
to completions properly.
(python-shell--get-multiline-input)
(python-shell--extra-completion-context)
(python-shell-completion-extra-context): New functions.
(python-shell-completion-at-point): Send text beginning from the line
start if the completion backend does not need word splitting. Remove
the detection of import statement because it is not needed anymore.
Create proper completion table based on completions returned from
different backends.
* test/lisp/progmodes/python-tests.el (python-tests--completion-module)
(python-tests--completion-parameters)
(python-tests--completion-extra-context): New helper functions.
(python-shell-completion-at-point-jedi-completer)
(python-shell-completion-at-point-ipython): New tests. (bug#68559)

Thanks, I understood your concern. I tried the new patch and
confirmed that your MyJediRL can be used as a custom completer by
storing it in a file specified in the PYTHONSTARTUP environment
variable. This may be the better way to go.
Sorry, I noticed one more thing. As written in the comments below, it
would be better to use `line-beginning-position' and
`line-end-position' instead of `pos-bol' and `pos-eol'.

Thanks for pointing it out! `pos-bol' was used because it can ignore
the prompt in `python-shell--get-multiline-input'. Fortunately, I find
`pos-bol' and `pos-eol' are available in the compat package since
29.1.1.0, so it should be enough to upgrade the compat version in
Package-Requires. I have updated the attached patch.

Subject: [PATCH] Respect the delimiter of completer in Python shell completion
* lisp/progmodes/python.el: (python-shell-completion-setup-code): Fix
the completion code of IPython. Change the return value to JSON string
and ...
(python-shell-completion-get-completions): ... simplify parsing.
(inferior-python-mode): Update docstring.
(python-shell-readline-completer-delims): New variable indicating the
word delimiters of readline completer.
(python-shell-completion-native-setup): Set the completer delimiter.
(python-shell-completion-native-get-completions): Convert output string
to completions properly.
(python-shell--get-multiline-input)
(python-shell--extra-completion-context)
(python-shell-completion-extra-context): New functions.
(python-shell-completion-at-point): Send text beginning from the line
start if the completion backend does not need word splitting. Remove
the detection of import statement because it is not needed anymore.
Create proper completion table based on completions returned from
different backends.
* test/lisp/progmodes/python-tests.el (python-tests--completion-module)
(python-tests--completion-parameters)
(python-tests--completion-extra-context): New helper functions.
(python-shell-completion-at-point-jedi-completer)
(python-shell-completion-at-point-ipython): New tests. (bug#68559)

Thanks, I installed it on the master branch.
What about the other patch, one you posted in
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=68559#46
Does that one need to be installed as well, or is it included in the
one I just installed?

The recent change on master, 0b9c7148fd, causes several failures in python-tests here (macOS). Log attached.
It seems to have something to do with completion. Maybe the new code is sensitive to details of Python's command line editor? The standard Python interpreter is unlikely to use GNU readline, for example.

If your emacs session hangs when starting python shells
recover with `keyboard-quit' and then try fixing the
interactive flag for your interpreter by adjusting the
`python-shell-interpreter-interactive-arg' or add regexps
matching shell prompts in the directory-local friendly vars:
+ `python-shell-prompt-regexp'
+ `python-shell-prompt-block-regexp'

Or alternatively in:

The python-*-completion-at-point-* tests never worked for me, and I
always assumed it was something specific to MS-Windows. But maybe
not. There was no change in the tests that fail for me before and
after the recent changes related to Python.

And, btw, on this Gnu/Linux system:
$ uname -a
Linux (REDACTED) 5.15.0-94-generic #104+11.0trisquel25 SMP Sat Feb 10 06:24:53 UTC 2024 x86_64 x86_64 x86_64 GNU/Linux
all the Python tests that failed for you still pass, with the current
master. So I wonder what is it that causes those failures on your
system.

Right, I don't think the Windows port is obscure enough to deserve test failures either; it's an unnecessary impediment. If it cannot easily be fixed then it's better to mark them to be skipped on Windows so that you don't see it every time you run 'make check'.
Completion in the Python shell worked on macOS before the change but now pressing TAB causes the process to hang, so something was clearly broken by the patch.

The standard Python installation on macOS uses a libedit-based readline module and the patch author probably didn't test the changes with that configuration.

Hi,
According to the log, the problem may be related to the json library,
which is introduced by the patch to convert the completion results
from Python to elisp. What is the version of Python on macOS? AFAIK
the json library is added to the Standard library since version 2.6.
If the library is not available, could you setup a Python virtual
environment containing the library and run the python tests in it?
Thanks!

The Python shell completion relies on the readline module, which is
not available for Python on MS-Windows. According to the instruction
in python.el:
;; readline based shell (it's known to work with PyPy). If your
;; Python installation lacks readline (like CPython for Windows),
;; installing pyreadline (URL `https://ipython.org/pyreadline.html')
;; should suffice. To troubleshoot why you are not getting any
;; completions, you can try the following in your Python shell:
;; >>> import readline, rlcompleter
;; If you see an error, then you need to either install pyreadline or
;; setup custom code that avoids that dependency.
It may be necessary to install pyreadline (for Python 2.7) or
pyreadline3 (for Python 3).

I don't know if I have CPython, but the above does show an error
message.

I will see if I can do that, thanks.
Regardless, patches to the test suite to skip the tests which rely on
those modules, if they aren't installed, will be welcome.

This is caused by the fact that the input is echoed back on MacOS
Python. This is described in etc/PROBLEMS:
*** In Inferior Python mode, input is echoed and native completion doesn't work.
The following log shows that it tries to parse the echoed back string
as a JSON string.
Test python-completion-at-point-1 backtrace:
json-parse-string("__PYTHON_EL_eval_file(\"/var/folders/qy/zstv16390
python--parse-json-array("__PYTHON_EL_eval_file(\"/var/folders/qy/zs
I think the echoed back string were ignored before the patch is
applied. However, after applying the patch, the returned string is
now parsed as JSON, which I believe is the reason for the error.
So one workaround would be to remove the echoed back string before
parsing as JSON.

Right, that bug needs to be fixed as well, but the echo problem existed prior to the change that broke the tests.
An alternative might be to disable the tty echo altogether. If I do it right after process creation then it has no effect; presumably Python or its readline module turns on echo just a bit later on. Anyway, running
import tty
tty.setraw(0)
in the python shell seems to put it right, with working completion and the annoying echo gone.

Yes, either that or turning off echo in the tty.

I've now installed pyreadline3, and I can confirm that the completion
tests which were failing before now pass.
Thanks.

This is still true.

I made prototype patches for each method. I don't use Mac so it would
be helpful if you could try these.
0001-Remove-echoed-back-string-in-python-shell-completion.patch
extracts only the last line to exclude echoed back strings.
0001-Set-tty-mode-to-raw-when-setting-up-Inferior-Python.patch sets
the Inferior Python tty to raw mode. python-ffap-module-path-1 will
no longer need to be skipped on Mac. If it is safe to set tty to raw
mode on all UNIX based systems, I prefer this method.
By the way, is it necessary to send
`python-shell-completion-setup-code' for every completion in
`python-shell-completion-get-completions'? To me it seems sufficient
to send it once at initialization.

Will this work on MS-Windows as well? If you are unsure, would you
please tell me how to test whether this works on Windows, so I could
collect the information for you?
Thanks.

Nice, thank you! I can confirm that they both appear to work, at least in the sense that the python-tests pass (except for the ones skipped intentionally), and the python shell behaves reasonable.
Only the set-tty-mode patch eliminates echo in the interactive python shell; in that sense it's preferable.
Both produce the very annoying warning
Warning (python): Your ‘python-shell-interpreter’ doesn’t seem to support readline, yet ‘python-shell-completion-native-enable’ was t and "python3" is not part of the ‘python-shell-completion-native-disabled-interpreters’ list. Native completions have been disabled locally. Consider installing the python package "readline".
which is not even correct since the standard Python does have a working readline module, even if it uses libedit.

Right, that test runs and passes.

Same here. I see no reason why it wouldn't be safe, either.

Indeed, it does seem a bit extravagant.

How about the following change, which only affects libedit-based
readline? It may enable native completion on mac, but I cannot test
it.

Thank you, but that change alone doesn't seem to suffice for python-tests to pass. Log attached.

It does not affect MS-Windows because it sets only when the tty
library can be imported. Although the tty library exists in
MS-Windows, importing the tty library will result in an error because
there is no underlying termios library.

You are right. Maybe the package name should be fixed to "gnureadline"
as described in etc/PROBLEMS.
On Mac, it might be better to set the default value of
`python-shell-completion-native-enable' to nil.

This would be one of the items for future improvement.

Disabling echo back may not be sufficient to enable native completions
on Mac. I have not tried raw mode, but have tried
readline.parse_and_bind('setty -echo') and
readline.parse_and_bind('edit on'). Native completions could be
enabled, but it was unstable.
I have no objection if Mac users check the above patch and if it is
OK.

Hi,
I cannot reproduce the problem with Python 3.12 and IPython 8.21. Can
you check the results with the following steps? Thanks.
1. start Python shell with IPython interpreter, i.e.
(setq python-shell-interpreter "ipython")
(setq python-shell-interpreter-args "-i --simple-prompt")
M-x run-python
2. M-x python-shell-completion-native-turn-off
3. eval code in the Python shell:
import re
from IPython.core.completer import provisionalcompleter
with provisionalcompleter():
print(list(get_ipython().Completer.completions('re.split("a",
"abc", maxs', 25)))
expected output: [<Completion start=21 end=25 text='maxsplit='
type='param', signature='?',>]
__PYTHON_EL_get_completions('re.split("a", "abc", maxs')
expected output: '[["maxsplit=", 21, 25, "param", ""]]'

Not sure why the inferior Python process doesn't act on a TAB being sent to it. Is the tty somehow in a state that disables readline/libedit? Something that Emacs does when setting up the pty?
Of course from a software engineering point of view, it's silly to send what essentially are edit keystrokes to Python and then screen-scrape the output. A proper interaction protocol would be the way to go, and would work equally well on any platform including Windows.

Afraid it wasn't.
Thanks for your patches. I suggest we apply your set-tty-raw patch on master now since it cures the test failures without breaking anything else (on Mac; I'm assuming no regression elsewhere).
Would you like me to do that for you?

Thanks. These all work as expected in 'emacs -Q', which made me realise
what may be the problem:
- the Emacs test suite runs under HOME=/nonexistent
- but PATH is unchanged
- I have the latest IPython installed locally using pipx:

Thank you for the investigation! I didn't realize the problem is
related to HOME=/nonexistent in 'make test'. Now I can also reproduce
it. In fact, I found that the test failure was caused by Jedi, as it
attempts to write cache to a non-existent directory.
When Jedi is directly used as the completion backend, more test
failures will be triggered:
PYTHONSTARTUP="$(python -m jedi repl)" make TEST_LOAD_EL=no test/python-tests
If the cache directory is writable, all tests will pass:
PYTHONSTARTUP="$(python -m jedi repl)" XDG_CACHE_HOME=~/.cache make
TEST_LOAD_EL=no test/python-tests
The attached patch should fix the problem.

On Mac, there are two independent problems. One problem, which
existed before Liu's patch was applied, is that native completions
cannot be enabled. The other problem is that the test now fails after
applying Liu's patch. Suppressing echo back solves the latter, but
not the former. Because of the former, leaving
`python-shell-completion-native-enable' at the default setting of t
will result in the warning.
There are two completions methods, native and non-native. If native
completions cannot be used, it falls back to non-native completions.
Native completions is triggered by sending TAB character, while
non-native completions is triggered by sending and evaluating
__PYTHON_EL_get_completions().
As far as I have tried, native completions cannot be enabled for
libedit-based readline package, even on Linux.
So, there are two ways for Mac users to avoid the warning. One is to
use gnureadline instead of libedit, and the other is to give up native
completions and set `python-shell-completion-native-enable' to nil.
This remains correct even with echo back disabled.
> Of course from a software engineering point of view, it's silly to send what essentially are edit keystrokes to Python and then screen-scrape the output. A proper interaction protocol would be the way to go, and would work equally well on any platform including Windows.
I think the protocol between python.el and inferior Python process is
already platform independent. Protocol violations are echo back.

Thanks! The patch fixes the error, but that's because
python-shell-completion-at-point-ipython is now skipped:
in particular, python-shell-readline-completer-delims evaluates to
"\s\t\n`~!@#$%^&*()-=+[{]}\\|;:'\",<>/?" rather than the empty string.
Any idea why that happens?

Did you find out why? Python responds nicely to TAB if run from a terminal, so what is it that we do in Emacs that prevents it from doing so? A TTY setting, or an environment variable (the TERM=dumb)?

Preferably neither. Emacs should adapt to the system environment, and in particular not warn about the default environment. A warning is an indication of a possible risk or other problem, and there is none here.
At most, python-mode could show a calm notice on the echo line but even that is a stretch. What do you think about this rough patch?

No, I meant a protocol that allows Emacs to act as a first-class Python front-end, not simulate a terminal, send keystrokes, use heuristics to determine what in the output stream is a prompt, REPL value, error, completion etc.
For example, it's a bit silly to input multi-line code in the REPL as a sequence of individual single-line commands, when we actually are inside a text editor that can edit multi-line Python code without a problem.
(I'm not suggesting that you or anybody in particular should do this; just that it's feasible. It would clearly be quite some work!)

"\s\t\n`..." is the delimiter used by rlcompleter, which is the
default completer used by the readline. rlcompleter cannot complete
module names or parameters, so in this case the native completion part
is skipped.
The test is intended to be used with Jedi as the completion backend,
e.g. setting PYTHONSTARTUP="$(python -m jedi repl)", or with a custom
IPython completer defined in the PYTHONSTARTUP file. I have updated the
patch to make the test use Jedi when possible.

Thanks, looks fine to me and runs without issue.
The python-shell-completion-at-point-ipython test is still skipped, with
or without specifying PYTHONSTARTUP="$(python -m jedi repl)", but like
you suggest that's not necessarily a problem.
I'm guessing you don't have write access to emacs.git, but have signed
the CA? If so, and if there are no other comments/objections in a few
days, I'll apply the patch in your name.
Thanks,

No, not exactly, but I don't think it is related to terminal settings.
python.el does not parse the completion candidates shown on the
terminal. Instead, it expects the candidates in a particular format,
which I call the protocol between python.el and inferior Python
process.
__PYTHON_EL_native_completion_setup() defined in
`python-shell-completion-native-setup' sets up the completer to do so.
We can test it by removing empty lines and pasting into Python REPL
outside Emacs. An example of typing "ra" and TAB using readline would
look like this.
>>> raraise
range
0__dummy_completion__ 1__dummy_completion__
>>> ra
However, when I use libedit-based readline and remove the raise line
in __PYTHON_EL_native_completion_setup(), it behaves like this.
>>> raraise
range
Please note that there is no dummy completions, and the new prompt is
not shown. When I hit TAB again, it would be like this.
>>> raraise
range
raise
range
0__dummy_completion__ 0__dummy_completion__ 0__dummy_completion__ 1__dummy_completion__
>>> ra
I think this difference in behavior is the reason why Native
completions does not work with libedit.

Personally, I think this patch would be fine.
I think we can also improve Non-native completions. Current
implementation sends the definition of __PYTHON_EL_get_completions()
every time. However, sending it once during initialization should be
sufficient. Worse, if the number of characters sent exceeds
`comint-max-line-length', it will be sent via file. This is happening
in your environment. Here is the log you presented.
Test python-completion-at-point-1 backtrace:
json-parse-string("__PYTHON_EL_eval_file(\"/var/folders/qy/zstv16390
Thanks to the echo back, we can see __PYTHON_EL_eval_file() was used.

I am not opposed to this approach, but as you wrote, it is very
different from the current inferior Python implementation.
Jupyter-emacs's approach may be similar to some extent. It uses zmq
as the communication channel.

Right. (The need for a file is just an artefact of Comint limitations, isn't it?)

Thank you, yes, in a sense it's a (small) step towards a more notebook-like interaction model, but Comint already has some of that. This problem is not unique to Python: other REPLs have to solve the problem of multi-line input as well, and it would serve the user if they all worked in the same way (as far as the language differences allow).
In Python's case, it would liberate us from the constraints of the standard terminal REPL.

I have no idea why the test is skipped. You may still check if native
completion works for IPython with following steps:
1. PYTHONSTARTUP="$(python -m jedi repl)" emacs -Q
2. start Python shell with IPython interpreter, i.e.
(setq python-shell-interpreter "ipython")
(setq python-shell-interpreter-args "-i --simple-prompt")
M-x run-python
There should be text "REPL completion using Jedi xxx" before the
first prompt in the Python shell buffer, and a message "Shell
native completion is enabled.".
3. type "import ab"/"open(enc" and press TAB
expected result: "import abc"/"open(encoding="

Hi Liu,
I noticed that with Non-native completions, Jedi completion is not
enabled even if PYTHONSTARTUP is set and "REPL completion using Jedi
0.18.2" is shown in inferior Python. Is this expected behavior? Jedi
completion is enabled regardless of PYTHONSTARTUP setting when I use
IPython with Non-native completions.

Yes, I think it is the limitation of comint. However, if the
definition is omitted, it is unlikely to reach that limit, since all
that is required is to send the string like
'__PYTHON_EL_get_completions("subproc")'.

Thanks for pointing out the problem! The attached patch should enable
Jedi completion for the non-native case.

This patch does not break anything further on macOS using the standard system Python.
I just thought you would be happy to know.

Thanks, I confirmed that the patch enables Jedi completion for the
non-native mode.

Oops:
$ PYTHONSTARTUP="$(python -m jedi repl)" ./src/emacs -Q
/home/blc/.pyenv/versions/3.12.2/bin/python: No module named jedi
Once I 'pip install jedi' the rest works as expected, and
python-shell-completion-at-point-ipython is no longer skipped.

This depth currently prepends the function to the hook, but in Emacs 24
it instead appends to the hook. Is that a problem?

Thanks for pointing it out! It is a problem because
python-shell-readline-detect is expected to be executed before
python-shell-completion-native-turn-on-maybe-with-msg, i.e. another
function in the hook. I have updated the patch.

Just curious: what does the empty string signify?
[ If it's not just a dumb question, perhaps the meaning could be added
to the variable's docstring/commentary. ]

The empty string means no characters are considered delimiters and the
readline completion could consider the entire line of input without
breaking it into parts based on typical delimiters like spaces or
punctuation. The docstring is updated in the attached patch.

Thanks! But that makes me wonder: in the cases where we check
(string= python-shell-readline-completer-delims "")
is there a possibility that the variable's value will be nil?
(In which case we should compare with equal instead of string=.)

Yes, it is a string with native completion and may be nil with
non-native completion. I have updated the patch. Thanks.
