[ANN] Spyder 3.0 seventh public beta release

[Carlos Córdoba]

Hi all,

On the behalf of the Spyder Project Contributors (https://github.com/spyder-ide/spyder/graphs/contributors), I’m pleased to announce the seventh beta of our next major version: Spyder 3.0.

We’ve been working on this version for more than two years now and as far as we know it’s working very well. There are still several bugs to squash but we encourage all
people who like the bleeding edge to give it a try. This beta version is released two weeks after our sixth one and it includes more than 200 commits.

Spyder 3.0 comes with several interesting and exciting new features. The most important ones are:

• Third-party plugins: External developers can now create plugins that extend Spyder in novel and interesting ways. For example, we already have plugins for the line-profiler and memory-profiler projects, and also a graphical frontend for the conda package manager. These plugins can be distributed as pip and/or conda packages for authors convenience.
• Improved projects support: Projects have been revamped and improved significantly in Spyder 3.0. With our new projects support, people will have the possibility of easily working on different coding efforts at the same time. That’s because projects save the state of open files in the Editor and allow Python packages created as part of the project to be imported in our consoles.
• Support for much more programming languages: Spyder relies now on the excellent Pygments library to provide syntax highlight and suggest code completions in the Editor, for all programming languages supported by it.
• A new file switcher: Spyder 3.0 comes with a fancy file switcher, very similar in spirit to the one present in Sublime Text. This is a dialog to select among the open
  files in the Editor, by doing a fuzzy search through their names. It also lets users to view the list of classes, methods and functions defined in the current file, and select
  one of them. This dialog is activated with Ctrl+P.
• A Numpy array graphical builder: Users who need to create NumPy arrays in Spyder for matrices and vectors can do it now in a graphical way by pressing Ctrl+M in the Editor or the Consoles. This will open an empty 2D table widget to be filled with the data required by the user.
• A new icon theme based on FontAwesome.
• A new set of default pane layouts for those coming from Rstudio or Matlab (under View > Window layouts).
• A simpler and more intuitive way to introduce keyboard shortcuts.
• Support for PyQt5, which fixes problems in MacOS X and in high definition screens.

pip install --pre -U spyder

Enjoy!

Hello there,

A small question on Spyder 3.0 beta on Windows (just installed using Anaconda on Win 8.1 x64):

When it starts, the Python process for default console is visible on Task Bar (just empty command-line window).

Is it new functionality or a bug?

Best regards,
Nikolay
