New in Elpy 1.24.0 ================== - Eldoc messages are a bit nicer now - Flymake has a useful modeline in Emacs 26 now, so Elpy won't hide it anymore - Elpy will now also use the Python shell to suggest completions New in Elpy 1.23.0 ================== - Use the new ``elpy-syntax-check-command`` variable to configure which syntax checker to use in Emacs 26 - Sending a "group" to the shell now uses the ``o`` suffix instead of ``g`` to avoid clashing with ``C-g`` New in Elpy 1.22.0 ================== - Elpy now supports the Black source code formatter. - Make Elpy work more nicely with the new Flymake. - Support Emacs 26.1 - Lots of bugfixes. New in Elpy 1.21.0 ================== - Debian now ships with elpy, you can use apt-get to install it. - Elpy now knows how to deal with the flymake in the upcoming Emacs release. - Some minor improvements in error messages and warnings. New in Elpy 1.20.0 ================== - No new features, but lots of bugfixes Thanks again to Gaby Launay for the continued and exceptional work! New in Elpy 1.19.0 ================== - Python 3.6 and Emacs 25.3 are now officially supported. - Sending code to a Python process is now a lot more convenient, see the documentation for more information. - Elpy can now automatically update the buffer displaying help for the symbol under point. Customize ``elpy-modules`` and enable the autodoc module there! - yapf and autopep8 now use their respective config files in the project root. - And tons of bugfixes. Thanks to Craig MacEachern, Daniel Gopar, Gaby Launay, Maxim Cournoyer, Nicholas D. Steeves and Sam Steingold for their help in making this release! New in Elpy 1.18.0 ================== - Elpy is now using MELPA Stable as the official distribution point. Please remove jorgenschaefer.github.io from your sources list if you still use it. It will not receive further updates after 1.18. - New commands for interacting with the Python shell, thanks to Rainer Gemulla. Check them out at https://elpy.readthedocs.io/en/latest/ide.html#evaluating-code-fragments - Shells started using ``C-c C-z`` will now use the project root as the current directory, to be in line with other code sending functionality. - importmagic has been removed. While this package added some nice functionality to Elpy, the way it worked by importing every module caused a lot of bugs. It was not an easy decision, but this is better for most Elpy users. - Rope is no longer supported for completions and similar functionality. Refactoring support using Rope is still there. Sadly, Rope has not received much of any update in a long time, and attempts to revive it failed. Maintaining multiple code paths to support both Jedi and Rope was complicated, so we decided to get rid of Rope for these features. Jedi is almost always an equivalent if not better choice. - The Green test runner is now supported by default. - Beyond all of this, there were numerous bugfixes. We are happy to report that Elpy now has more maintainers! Daniel Gopar, Rainer Gemulla and @galaunay are now helping regularly with this project. Thanks to all the contributors! New in Elpy 1.17.0 ================== - The xref functionality in newer Emacsen is now supported for following symbols at point. - Elpy now supports PEP 397 for Windows executable names. - In addition to pylint, Elpy now also supports epylint correctly. - A number of features for working with interactive Python have been added to Elpy; e.g., commands for sending code fragments to the Python shell and the ability to echo their output in the message area. See the documentation for a full list. - Bunch of little bugfixes. New in Elpy 1.16.0 ================== - You can now change which function is used to run test commands, instead of the default ``compile``, using ``elpy-test-compilation-function``. This allows using ``pdb`` to run tests in a debugger, for example. - Elpy now sets ``IPY_TEST_SIMPLE_PROMPT``, which should prevent a number of problems with IPython 5. - If you like Elpy, you can now sponsor its development using Patreon at https://www.patreon.com/jorgenschaefer New in Elpy 1.15.0 ================== - Elpy now supports profiling, try ``elpy-profile-buffer-or-region``! - Do not randomly downcase completion candidates anymore. - Work around a bug in Emacs 25.1 and before related to current IPython shells. - And lots of other bugfixes. New in Elpy 1.14.0 ================== - Basic Django support. Try ``C-c C-x c`` and ``C-c C-x r``! Thanks to Daniel Gopar for this. - You can now use manage.py to run Django tests, instead of always using django-admin.py. - When called with a prefix argument ``elpy-importmagic-add-import`` will now ask for an alias name to import as. New in Elpy 1.13.0 ================== - Fewer surprises with syntax checks, ``C-c C-z``, reformatting - Improved behavior for reformatting. - Improved documentation for IPython. IPython 5 broke a lot of things with Emacs. Use it at your own risk. New in Elpy 1.12.0 ================== - Some symbols can now be completed with parentheses after them, useful for functions. The heuristic for when to add parentheses and not is not optimal, so this is not enabled by default—customize ``elpy-company-post-completion-function`` to enable this feature. - Support dedicated Python shells (one per Python file). You can customized ``elpy-dedicated-shells`` to make this the default. - Elpy now uses ``python -m pip`` instead of pip directly to improve interaction with virtualenvs. - Support for Python 2.6 has been officially dropped. - Display for backend errors has been disabled by default. Jedi has not had a release in a long while, and many bugs have been unfixed. These errors have only caused added workload for Elpy maintainers. The option will be reverted once Jedi has had a new release. New in Elpy 1.11.0 ================== - Elpy now supports yapf to format your code. - You can now adjust whether Elpy should hide modes from the mode line or not using ``elpy-remove-modeline-lighter`` - When the new option ``elpy-disable-backend-error-display`` is set, Elpy will not show its error pop-up anymore. This can be useful if you run into an annoying bug in Jedi, for example. - New command ``elpy-goto-definition-other-window`` on ``C-x 4 M-.``. - Expanding ``super`` now gives the short form supported in Python 3. - All Rope errors are now caught, as the upstream maintainers did not show interest in distinguishing between malformed input and bugs in their library. New in Elpy 1.10.0 ================== - Marking the current indentation level at the top level will now mark the whole buffer. - The region will be normalized before re-indenting it, making the behavior more predictable for partially marked lines. - Using autopep8 on the whole buffer will now keep point (roughly) at the same location as it was. - The autopep8 code now also uses the same configuration options as the command line tool. - Malformed JSON data from the backend is now handled better. - RPC processes are restarted when the current virtualenv changes. - Python 3.5 is now officially supported. - Flymake will now not be enabled in buffers without file name, where it can't run anyhow, or when the checker program does not exist in the first place. - It is now possible to ask Elpy not to remove the mode line lighter of company mode, which can be useful if you use company in other modes. - Test discovery now also allows file names without "test" in them to be tested. Classes and methods still require the substring, though. - Spurious equals signs at the end of completions from Jedi will now be ignored. - Various other bug fixes. New in Elpy 1.9.0 ================= - Elpy now supports the ``autopep8`` library for automatically formatting Python code. All refactoring-related code is now grouped under ``C-c C-r``. Use ``C-c C-r i`` to fix up imports using importmagic, ``C-c C-r p`` to fix up Python code with autopep8, and ``C-c C-r r`` to bring up the old Rope refactoring menu. - ``C-c C-b`` will now select a region containing surrounding lines of the current indentation or more. - ``C-c C-z`` in a Python shell will now switch back to the last Python buffer, allowing to use the key to cycle back and forth between the Python buffer and shell. - The pattern used for ``C-c C-s`` is now customizeable in ``elpy-rgrep-file-pattern``. - ```` now can be used to send the current statement to the Python shell. Be careful, this can break with nested statements. - The Elpy minor mode now also works in modes derived from ``python-mode``, not just in the mode itself. New in Elpy 1.8.1 ================= - Ignore a ``KeyError`` from Jedi 0.9.0 which occurs a lot in normal code. New in Elpy 1.8.0 ================= - Emacs 24.5 is now officially supported - The new configuration option ``elpy-rpc-ignored-buffer-size`` defines a maximum buffer size to be handle completion in, to avoid laggy interaction in unusually large files - Indentation block movement was replaced with code that just moves the marked block or the current line; this should be a lot less magical and more predictable - Running the test at point now correctly ignores any inner methods - Jedi docstrings now show the full name of the object - The RPC interpreter is now chosen correctly on cygwin - ``elpy-shell-send-region-or-buffer`` now warns of tabs in the data being sent - Elpy now binds stdout and stderr to ``/dev/null`` to avoid being confused by spurious output from other libraries - RPC buffers (and processes) are removed after some time to avoid them piling up endlessly - It is not possibly anymore to use customize alone to use ipython, because of some bad interaction between custom options in Elpy and python.el - And lots of bugfixes (50 issues closed!) New in Elpy 1.7.1 ================= - Do not fail on errors from importmagic. - Handle new minor mode behavior of new versions of yasnippet. - Do use the argument to ``elpy-use-ipython`` correctly. - Handle unexpected data from the backend more gracefully. New in Elpy 1.7.0 ================= - Elpy now can add missing import directives automatically, by using Alec Thomas' excellent importmagic_ library. Use ``C-c C-m`` to add a single import statement, or ``C-c C-S-m`` to include all missing import statements. Many thanks to Georg Brandl for doing a lot of work to bring this feature to Elpy! - The Jedi backend now also supports ``C-c C-d`` to display a docstring. Thanks again to Georg Brandl for the patch. - It is now possible to disable the display of the current function in the echo area by setting ``elpy-eldoc-show-current-function`` to ``nil``. - idomenu was removed. - Twisted's Trial test runner is now supported. Thanks to Elric Milon for the patch! - All test runners now use a variable to decide which command to run, which for example allows using ``manage.py`` for the Django test runner, or your own test script which sets up the environment correctly. - Emacs 24.4 is now officially supported. - Various bugfixes. .. _importmagic: https://github.com/alecthomas/importmagic New in Elpy 1.6.0 ================= - When point is on a line with a flymake error, Elpy will now show the error in the echo area. - The movement commands (``C-``) have been reworked again. Going left and right will now move by indentation levels left of the current indentation, i.e. jump four spaces, and by words right of the current indentation. Going up and down will go to the previous or next line with the indentation level point is at, not the indentation the line has. Try it, it's more difficult to explain than to use. - Completion results are now sorted more sensibly, with single-underscore symbols at the end, and double-underscore symbols after normal symbols, but before single-underscore ones. - ``M-x elpy-config`` will now point out if there are newer versions available for packages used by Elpy. - ``M-x elpy-config`` will now warn if ``~/.local/bin`` is not in ``PATH`` while there is no virtualenv active. - The ``M-x elpy-version`` command is back by popular demand. - RPC buffers used by Elpy are now hidden by default, having a space at the beginning of the name. - When the Rope library throws an error, Elpy will now also attempt to provide reproduction steps. This used to only happen for Jedi. - Various bug fixes. New in Elpy 1.5.1 ================= - Fix a bug where company-mode might get confused about the current backend, leading to an error about ``Symbol's function definition is void: nil`` - Fix Rope so it won’t search the whole project directory. This was an intended feature in v1.5 which did not work originally. - Use ``yas-text`` instead of ``text`` in snippets for compatibility with the unreleased yasnippet from MELPA (thanks to Daniel Wu!) New in Elpy 1.5.0 ================= - Elpy now has a `manual`_. Additionally, there's a menu bar now which should make it easier to discover Elpy features. - The Elpy Python package now ships with the Emacs Lisp package, removing the need to install Elpy via pip. - Python 3.4 is now officially supported. - The new command ``elpy-config`` can be used to configure Elpy using Emacs' built-in customize system. Elpy has been changed to make the most of this. - Elpy now uses company-mode instead of auto-complete for on-the-fly auto completion. This changes a few things. There is no automatic documentation popup anymore. Instead, you can type ``C-d`` and get the documentation buffer. In addition, you can type ``C-w`` to see the source of the current candidate in context. - Elpy now uses pyvenv as the virtualenv module, enabling virtualenvwrapper hooks. - We now ship with a large number of YASnippet snippets. Try ``M-x yas-insert-snippet``. - The new unified test running interface on ``C-c C-t`` will try to determine the current test and run it, or, failing that, run all tests. Provide a prefix argument to just run all tests no matter what. You can change the test runner to be used using ``elpy-set-test-runner``. Elpy supports the default unittest discover runner, the Django discover runner, nosetests and py.test by default. New test runners can easily be defined. - There's a new multi-edit functionality. ``C-c C-e`` will edit all occurrences of the symbol under point. When using Jedi, this is using semantic information as opposed to just syntactic one. When a region is active, edit all occurrences of the text in region in the current buffer. - When sending Python code to the interactive interpreter using ``C-c C-c``, Elpy will now not automatically pop to the interpreter anymore. Use ``C-c C-z`` to switch to the interpreter. - Elpy will now display the current class and function if there is no call tip to be displayed. Removes the ``C-c C-q`` binding. - If there is a call tip, highlight the current argument (requires Jedi). - The documentation interface using ``C-c C-d`` is much smarter now, falling back to pydoc when necessary and providing sensible completion for that, too. Provide a prefix argument if you want no smarts, just pydoc. - ```` and ```` now open a line below or above the current one. - ```` will now navigate between Python blocks of the same indentation level. ```` will move the current block. Try it, it's easier to understand when you see it than to explain it. - There's a new concept of modules. The variable ``elpy-default-minor-modes`` is gone (use ``elpy-mode-hook`` for minor modes). Instead, there's now ``elpy-modules`` which can be used to enable or disable certain features of Elpy. - ``elpy-clean-modeline`` is gone, modules now clean themselves up. - Elpy now distinguishes between the project root, where project files are located, and the library root, which should be part of ``sys.path`` to import the module under development. - ``elpy-project-ignored-directories`` replaces the old ``elpy-rgrep-ignored-directories`` and is used by more features. - ``elpy-doc-websearch`` has been removed as it was barely useable as is. - Elpy now tries to be more helpful when errors in the backend happen. This removes ``elpy-rpc-traceback``, as that will be displayed by default. - Optimizations were added to handle large files, making general interaction a lot faster. - When Rope is being used, do not search through unusually large directories. This should speed up interaction in those cases, especially when editing a file in the home directory. - And a whole lot of minor bug fixes and little improvements. .. _manual: https://elpy.readthedocs.io/ New in Elpy 1.4.2 ================== - Minor bugfix to prevent an error from projectile-project-root to interfere with Elpy’s project finding strategy. New in Elpy 1.4.1 ================= - Elpy now sets project-wide preferences for Rope, enabling completion in the sys package, among others. - An error is avoided in the Jedi backend when trying to go to symbols in compiled packages. - A compatibility alias was added for nose.el, which insists on breaking backwards compatibility with Emacs 24.x. New in Elpy 1.4.0 ================= - Elpy has moved to its own ELPA. Make sure to update your package-archives (as described above). - For a file in a Projectile-managed project is opened, Elpy will now use Projectile’s project root. - When the user has set a valid python-check-command, elpy will now refrain from overriding it. - On Windows, elpy is now using the pythonw.exe interpreter for the RPC process, as that seems to be causing fewer issues. - And various smaller bugfixes. New in Elpy 1.3.0 ================= - virtualenv.el has been replaced by pyvenv.el, as that library offers more features. - elpy-rpc-restart now works globally, not just in Elpy buffers. - Elpy does not try to complete in comments anymore. - The new command elpy-rpc-traceback gives access to the last stack trace in the Elpy backend, helping with debugging problems. - The flymake check function is now run with the current directory as / to avoid accidental imports. - Ensure correct handling of yas-snippet-dirs by Elpy. This variable can be a string, so ensure it’s a list before adding to it. - The new variable elpy-show-installation-instructions can be used to disable the installation screen. - Fix a very nasty bug causing spurious empty lines in a buffer or consume 100% CPU in certain situations when using the Jedi backend. Thanks to Matthias Dahl for finding this bug. - Various other bugfixes. New in Elpy 1.2.1 ================= Bugfix release. - The refactoring was not ported to the new asynchronous API, resulting in an error when refactoring was attempted. - The project root now always returns a directory. Too many parts of elpy relies on this. If the project root turns out to be your home directory, elpy will warn you about it. - Elpy now works correctly with Emacs 24.2. There were some compatibility functions missing. - Blocking RPC calls now do not block for one second even if there is process output. New in Elpy 1.2 =============== - Elpy now uses asynchronous RPC. This means that Emacs should not freeze anymore while eldoc or auto-complete functions run. - ``elpy-shell-send-region-or-buffer`` will now remove common indentation of the region, making it possible to easily send parts of an if statement or function body without manually adjusting the indentation. - The Python package depends on ``flake8``, and will also try to be smarter when detecting ``flake8`` for on-the-fly checking. - ``elpy-check`` can be run with a prefix argument to check the whole project, instead of only the current file. - ``elpy-rgrep-symbol`` now ignores a few common directories (``.tox``, ``build``, ``dist``). - When using the rope backend, Elpy will not create the ``.ropeproject`` folders anymore. This should keep projects a lot cleaner. New in Elpy 1.1 =============== - Elpy now always uses the root directory of the package as the project root; this should avoid some confusion and improve auto-completion suggestions - ``elpy-shell-send-region-or-buffer`` now accepts a prefix argument to run code wrapped behind ``if __name__ == '__main__'``, which is ignored by default - ``elpy-project-root`` is now a safe local variable and can be set from file variables - Elpy now supports project-specific RPC processes, see ``elpy-rpc-project-specific`` for how to use this - ``M-*`` now works to go back where you came from after a ``M-.`` - Elpy now ships with a few dedicated snippets for YASnippet - Support and require Jedi 0.6.0 New in Elpy 1.0 =============== - Version 0.9 was a release candidate, so this release focused on bug fixes instead of new features. - ``elpy-enable`` now takes an optional argument that skips variable initialization for those users who prefer their own defaults for other modes. - ``python-check.sh`` has been removed from Elpy, as the flake8 tool from pypi does everything it does, only better. - Elpy will now start the helper subprocess in the root directory, avoiding accidental Python path clobbering. New in Elpy 0.9 =============== - Elpy now officially support Python 2.6, 2.7 and 3.3 on Emacs 24.2 and 24.3, with continuous integration tests thanks to `Travis CI`_. - Extended support for Pydoc. ``C-u C-c C-d`` will now prompt for an auto-completed symbol to run Pydoc on. The pydoc output will be formatted and placed in a help buffer for easy review. - Refactoring support is back. ``C-c C-r`` will pop up a refactoring wizard offering various refactoring options. Most of them depend on the presence of Rope, though, even if Jedi is used as a completion backend. - The Rope backend has been extended to provide completions for modules in an import clause. - New refactoring option: Add missing imports. This will search for undefined symbols in the current file and automatically add appropriate imports. - ``C-c C-c (elpy-rgrep-symbol)`` now prompts for a regexp when a prefix argument is given instead of using the symbol at point. .. _Travis CI: https://travis-ci.org/ New in Elpy 0.8 =============== Python Backend Rewrite ---------------------- - Elpy does not use Pymacs, Ropemacs and Ropemode anymore, but instead provides its own Python interface with the elpy package on PyPI. - This not only should improve performance, but also enables using Jedi as an alternative backend for completion. Use ``M-x elpy-set-backend`` to change between rope and jedi. For now, this does disable all refactoring support, though. Project Support --------------- - Elpy now has built-in project support. The interface is rather simple: You can set ``elpy-project-root`` to the correct value in ``.dir-locals.el``, or just rely on the automatic detection. If you change your mind, you can always just ``elpy-set-project-root``. - New dependency: Find File in Project (ffip), bound to ``C-c C-f`` by default. This will allow you to find files anywhere in your project using a search-as-you-type interface like ido. - New dependency: nose, bound to ``C-c C-t`` by default. This will run the nosetests binary in the root of your current library directory. You can restrict the tests being run to the current test or the current module by adding prefix arguments. - New function: Recursive grep for symbol, bound to ``C-c C-s`` by default. This will search for the symbol at point in the whole project. New dependencies ---------------- - idomenu, bound to ``C-c C-j`` by default. This replaces the standard imenu interface with an ido-based search-as-you-type interface for definitions in the current buffer. - virtualenv.el, replacing pyvirtualenv.el). Use ``M-x virtualenv-workon`` to enable a virtualenv. - iedit.el, bound to ``M-,`` by default. This highlights all occurrences of the symbol at point or the active region in the current buffer or narrowing. When you edit any of them, all others will be edited the same. This allows some basic and very quick refactoring. - New variable ``elpy-default-minor-modes`` which is run by ``elpy-mode`` on startup. If you don’t want to use some modes, remove them from here. Key Bindings and Functions -------------------------- - The key bindings have been reworked and cleaned up. Sorry, this might cause confusion. - Yasnippet is now on its own keybinding, ``C-c C-i``, instead of sharing the auto-complete interface. This was done because some snippets conflicted with legitimate, unsnippy completions. - New function: Occur Definitions, bound to ``C-c C-o`` by default. This will run the standard occur command to show definitions (classes and functions) in your current buffer, giving you a very quick outline and the ability to jump to different definitions quickly. - New function: Show Defun, bound to ``C-c C-q`` by default. This will show the current method and possibly class in the mode line, which is helpful in long functions. - New functions: Forward/backward definition, bound to ``M-n`` and ``M-p`` as well as ```` and ```` by default. These will jump to the next or previous definition (class or function), helping with quick navigation through a file. Miscellaneous ------------- - The documentation function (``C-c C-d``) now uses pydoc when a prefix arg is given. - The web search function (``C-c C-w``) now searches for the current symbol by default. The tab-completing web documentation interface was removed and is scheduled to be replaced with a new pydoc interface in future versions. - The ``python-check.sh`` is now shipped with elpy. If you load elpy.el before you load python.el, it should be the default ``python-check-command``.
