Subject: [PATCH 056/864] Allow bpython/bpdb outside main thread

Because [signal.signal][1] is only allowed to be called from the main
thread, if you use bpdb in another thread it will crash upon entering
the repl.  By ignoring the resulting `ValueError` the show can go on.

Subject: [PATCH 098/864] Fix bpython-curses bug when passed an argument

Currently, running `bpython-curses -i file.py` results in:

```
...
  File ".local/share/virtualenvs/flask-ex-03Wix3mp/lib/python3.6/site-packages/bpython/cli.py", line 1905, in main_curses
    bpython.args.exec_code(interpreter, args)
NameError: name 'bpython' is not defined
```

This PR addresses this error by correctly importing args and using it,
like the curtsies implementation.

Subject: [PATCH 118/864] Display the correct signature for a decorated
 function in Python 3

This patch changes it so that `inspect.signature` is used instead of
`inspect.getfullargspec` to get a function's signature, when using Python 3.

Python 3.3 introduced the `inspect.signature` function as a new way to get the
signature of a function (as an alternative to `inspect.getargspec` and
`inspect.getfullargspec`).  `inspect.signature` has the advantage that it
preserves the signature of a decorated function if `functools.wraps` is used to
decorated the wrapper function.  Having a function's signature available is very
hepful, especially when testing things out in a REPL.

Subject: [PATCH 119/864] Correctly reference inspect parameter kinds

Instead of referencing parameter kinds as class attributes on the private
`_ParameterKind` class we reference them on the public `Parameter` class.  This
has two advantages:

1) We don't use a private interface.
2) The class attributes on `_ParameterKind` have only been added in Python 3.5,
   but on `Parameter` they have existed since Python 3.3.

Subject: [PATCH 120/864] Catch function signature inspection errors for
 built-in types

Some built-in functions (e.g. `map`) can't be inspected with
`inspect.getargspec`, `inspect.getfullargspec` or `inspect.signature`.  The
exceptions from `inspect.getargspec` and `inspect.getfullargspec` are all caught
in the code, but `inspect.signature` raises a `ValueError` instead of a
`TypeError`.  This exception is now also caught.

Subject: [PATCH 122/864] 10x the too low hist_length default of 100 to 1000

I just lost a useful function I wrote that I hoped I could find in the history file.
a utf-8 encoded history file having 1000 lines of code less that 80 columns/characters long less than ~80 kilobytes in size.
or is the concern more about the look up time for autocomplete and the responsiveness of typing?

+* Usage in combination with Python 2 has been deprecated. This does not mean that

Subject: [PATCH 182/864] reconfigure and rename formatforfile

- New name: get_session_formatted_for_file
- No longer takes parameters as it can refer directly to all_logical_lines
- send_session_to_external_editor now call this method instead of
doing a very similar process
- Now "# OUT:" refers to output and "### " refers to current line

@@ -52,6 +56,64 @@ Start bpython by typing ``bpython`` in your terminal. You can exit bpython by
 using the ``exit()`` command or by pressing control-D like regular interactive
 Python.
 
+Installation via OS Package Manager
+-----------------------------------
+
+The majority of operating system of desktop computers comes with a package
+manager system, if you are any user of them, you can install ``bpython``
+using the package manager.
+
+Ubuntu/Debian
+~~~~~~~~~~~~~
+Ubuntu/Debian family Linux users and install bpython using the apt package manager, using the
+command with sudo priviledge:
+
+.. code-block:: bash
+
+    $ apt install bpython
+
+In case you are using an older version, run
+
+.. code-block:: bash
+
+    $ apt-get install bpython
+
+Arch Linux
+~~~~~~~~~
+Arch linux uses pacman as the default package manager, and you can use it to install bpython:
+
+.. code-block:: bash
+
+    $ pacman -S bpython
+
+
+Windows
+~~~~~~~
+**Caveats:** As ``bpython`` makes use of the ncurses library of \*nix-family operating systems,
+bpython on Windows is not officially supported and tested.
+
+However, you can still use bpython on Windows using a somewhat work around. Briefly, you should install
+these two packages using pip:
+
+.. code-block:: bash
+
+    $ pip install bpython windows-curses
+
+Then you should invoke a program called ``bpython-curses.exe`` instead of ``bpython.exe`` to use bpython:
+
+.. code-block:: bash
+
+    $ bpython-curses
+
+Mac OS
+~~~~~~
+Like Windows, Mac OS does not include a package manager by default. If you have installed any
+third-party pacakge manager like MacPorts, you can install it via
+
+.. code-block:: bash
+
+    $ sudo port install py-bpython

Subject: [PATCH 381/864] Only replace importers not from six (fixes #874)

reload, however not breaking six is more important.

The code now also only provides some functions of the underling
finder/importer also does.

 autocomplete_mode
 ^^^^^^^^^^^^^^^^^
-There are three modes for autocomplete. simple, substring, and fuzzy.  Simple
-matches methods with a common prefix, substring matches methods with a common
-subsequence, and fuzzy matches methods with common characters (default: simple).
-
-As of version 0.14 this option has no effect, but is reserved for later use.
+There are four modes for autocomplete: ``none``, ``simple``, ``substring``, and
+``fuzzy``. Simple matches methods with a common prefix, substring matches
+methods with a common subsequence, and fuzzy matches methods with common
+characters (default: simple). None disables autocompletion.

Subject: [PATCH 527/864] Mypy types for completion (#928)

* Mypy types for completion

We're not checking these in CI nor are we providing a config file yet.
I used mypy 0.910 in Python 3.6 run directly on bpython/autocomplete.py and still had 3 errors after these changes.

-Installation via OS Package Manager
------------------------------------
-
-The majority of desktop computer operating systems come with package management
-systems. If you use one of these OSes, you can install ``bpython`` using the
-package manager.
-
-Ubuntu/Debian
-~~~~~~~~~~~~~
-Ubuntu/Debian family Linux users can install ``bpython`` using the ``apt``
-package manager, using the command with ``sudo`` privileges:
-
-.. code-block:: bash
-
-    $ apt install bpython
-
-In case you are using an older version, run
-
-.. code-block:: bash
-
-    $ apt-get install bpython
-
-Arch Linux
-~~~~~~~~~~
-Arch Linux uses ``pacman`` as the default package manager; you can use it to install ``bpython``:
-
-.. code-block:: bash
-
-    $ pacman -S bpython
-
-Fedora
-~~~~~~~~~~
-Fedora users can install ``bpython`` directly from the command line using ``dnf``.
-
-.. code-block:: bash
-
-    $ dnf install bpython
-
-Windows
-~~~~~~~
-**Caveats:** As ``bpython`` makes use of the ncurses library of \*nix-family operating systems,
-bpython on Windows is not officially supported and tested.
-
-However, you may still use bpython on Windows using a workaround. In brief, you should install
-these two packages using ``pip``:
-
-.. code-block:: bash
-
-    $ pip install bpython windows-curses
-
-Then you should invoke a program called ``bpython-curses.exe`` instead of ``bpython.exe`` to use bpython:
-
-.. code-block:: bash
-
-    $ bpython-curses
-
-Mac OS
-~~~~~~
-Like Windows, Mac OS does not include a package manager by default. If you have installed any
-third-party package manager like MacPorts, you can install it via
-
-.. code-block:: bash
-
-    $ sudo port install py-bpython

release tag instead of the X-dev tag. During development, we always want
it to use the X-dev tag, however.

Subject: [PATCH 747/864] Fix inspection of built-in functions with >= 3.11

The built-in functions no longer have their signature in the docstring,
but now inspect.signature can produce results. But as we have no source
for built-in functions, we cannot replace the default values. Hence, we
handle built-in functions in an extra step.

This commit also changes the handling of default values slightly. They
are now always put into a _Repr.

`setup.py` expects to be able to find git tags in order to properly set
the package version. If a fork does not have any tags, `pip install -e
.` will fail due to the default `"unknown"` being an invalid version.

 There are no official binaries for bpython on Windows (though this is something

-The easiest way to get `bpython.cli` (the curses frontend running) is to install
-an unofficial windows binary for pdcurses from:
-http://www.lfd.uci.edu/~gohlke/pythonlibs/#curses. After this you can just
-`pip install bpython` and run bpython curses frontend like you would on a Linux

Subject: [PATCH 824/864] More general adaptation of showsyntaxerror() to
 Python 3.13

Python 3.13's code.InteractiveInterpreter adds a new **kwargs
argument to its showsyntaxerror() method. Currently, the only
use of it is to send a named argument of name "source". Whilst
the current adapation of repl.Interpreter is specific and should
work in the short term, here is a more general solution.
