[ANN] Spyder 6.1.0a2 is released!

[Daniel Althviz Moré]

Hi all,

On behalf of the Spyder Project Contributors, I'm pleased to announce the second alpha of our next minor version: Spyder 6.1.

We've been working on this version for around half a year now and it's working relatively well. We encourage all people who like the bleeding edge to give it a try.

Spyder 6.1 comes with the following interesting new features and fixes:

• New features

  • Add support to work with multiple cursors to the Editor. Options to configure them are available in Preferences > Editor > Advanced settings.
  • Add a graphical interface to the update process of our standalone installers.
  • Paths can be added to the front of sys.path in the Pythonpath manager.
  • Copy/cut the current line if nothing is selected in the Editor with Ctrl+C/Ctrl+V, respectively.
  • Add option to show/hide the Editor's file name toolbar to Preferences > Editor > Interface.
  • Select full floating point numbers by double-clicking them on the Editor and the IPython console.

• Important fixes

  • Much better support for PyQt6 and PySide6.

• UX/UI improvements

  • Add option to hide all messages displayed in panes that are empty to Preferences > Application > Interface.

• API changes

  • Editor

    • Breaking - The NewFile, OpenFile, OpenLastClosed, MaxRecentFiles, ClearRecentFiles, SaveFile, SaveAll, SaveAs, SaveCopyAs, RevertFile, CloseFile and CloseAll actions were moved to the ApplicationActions class in the Application plugin.
    • Breaking - The shortcuts "new file", "open file", "open last closed", "save file", "save all", "save as", "close file 1", "close file 2" and "close all" were moved to the "main" section.
    • Add open_last_closed, current_file_is_temporary, save_all, save_as, save_copy_as and revert_file methods.

  • IPython console

    • Breaking - Remove set_working_directory method. You can use set_current_client_working_directory instead, which does the same.
    • Breaking - The save_working_directory method was made private because it's only used internally.
    • Add sender_plugin kwarg to the set_current_client_working_directory method.

  • Working Directory

    • Breaking - The sig_current_directory_changed signal now emits two strings instead of a single one.
    • Breaking - The sender_plugin kwarg of the chdir method now expects a string instead of a SpyderPluginV2 object.

  • Remote Client

    • Breaking - The create_ipyclient_for_server and get_kernels methods were removed.
    • Add sig_server_changed signal to report when a server was added or removed.
    • Add get_server_name method to get a server name given its id.
    • Add register_api and get_api methods in order to get and register new rest API modules for the remote client.
    • Add get_jupyter_api method to get the Jupyter API to interact with a remote Jupyter server.
    • Add get_file_api method to get the SpyderRemoteFileServicesAPI rest API module to manage remote file systems.

  • Pythonpath manager

    • Breaking - The sig_pythonpath_changed signal now emits a list of strings and a bool, instead of two dictionaries.

  • Application plugin

    • Add create_new_file, open_file_using_dialog, open_file_in_plugin, open_last_closed_file, add_recent_file, save_file, save_file_as, save_copy_as, revert_file, close_file, close_all and enable_file_action methods to perform file operations in the appropriate plugin.
    • Add focused_plugin attribute.

  • SpyderPluginV2

    • Add CAN_HANDLE_FILE_ACTIONS and FILE_EXTENSIONS attributes and create_new_file, open_file, get_current_filename, current_file_is_temporary, open_last_closed_file, save_file, save_all, save_file_as, save_copy_as, revert_file, close_file and close all methods to allow other plugins to hook into file actions.
    • Add sig_focused_plugin_changed signal to signal that the plugin with focus has changed.

  • PluginMainWidget

    • Add SHOW_MESSAGE_WHEN_EMPTY, MESSAGE_WHEN_EMPTY, IMAGE_WHEN_EMPTY, DESCRIPTION_WHEN_EMPTY and SET_LAYOUT_WHEN_EMPTY class attributes, and set_content_widget, show_content_widget and show_empty_message methods to display a message when it's empty (like the one shown in the Variable Explorer).

  • Shellconnect

    • Breaking - Rename is_current_widget_empty to is_current_widget_error_message in ShellConnectMainWidget.
    • Add switch_empty_message to ShellConnectMainWidget to switch between the empty message widget and the one with content.
    • Add ShellConnectWidgetForStackMixin class for widgets that will be added to the stacked widget part of ShellConnectMainWidget.

  • AsyncDispatcher

    • Breaking - Remove dispatch method to use it directly as decorator.
    • Add class DispatcherFuture to spyder.api.asyncdispatcher and QtSlot method to AsyncDispatcher so that connected methods can be run inside the main Qt event loop.
    • Add early_return and return_awaitable kwargs its constructor.
