Many thanks to them!</em></p> <p>Assistant is a new view in Thonny, which observes your program runs and offers help if you get an exception or if it finds something fishy in your code. It uses <a class="reference external" href="https://www.pylint.org/">Pylint</a> and <a class="reference external" href="http://mypy-lang.org/">MyPy</a> for static analysis and custom dynamic analysis for understanding the error situations better.</p> <p>Here is an example:</p> <img alt="https://thonny.org/img/assistant.png" src="https://thonny.org/img/assistant.png"/> <p>Many error types are not supported yet – you may even call it a proof of concept for now. Here is where your help is needed – if you meet a situation where Assistant could be more helpful, then click on the feedback link at the bottom of the view and let us know!

Although the performance has been greatly improved in 3.0 beta, larger programs would still benefit from a more efficient solution.</p> <p>Thonny now has <strong>two debug modes</strong>. Beside the original AST-based debug mode – <strong>the “nicer” one (Ctrl+F5)</strong>, there is new, traditional line-based mode – <strong>the “faster” one (Shift+F5)</strong>. The new mode is not as intuitive but much more efficient. We expect that most students start with the nicer debuger and move on to the faster one when their programs grow bigger.</p> <p>By default the new debugging mode still uses stacked windows for presenting the call stack. This gives good intuition about the concept, but it may become cumbersome to use. Therefore in 3.0 one can choose between <strong>two different styles for presenting call stack</strong>. In “Tools → Options → Debugger” you can switch to more traditional style with a separate view for presenting and switching call frames. Note that both styles can be used with both debugging modes.</p> <p>Last, but not least, Thonny finally supports <strong>breakpoints</strong>. For using them, you need to switch on line numbers (Tools → Options → Editor). This gives you the margin, where you can add or remove breakpoints with double-clicks. Note that you don’t need to use breakpoints – if you start the debugger without breakpoints, Thonny stops before the first statement, just like it used to.</p> </div> <div class="section" id="new-default-back-end"> <h2>New default back-end</h2> <p>Thonny 2.1 introduced automatically managed virtual environment as default back-end. The idea was to allow students start from clean slate and add packages later without worrying about the integrity of whole system. It turned out that many instructors did not like this scheme as it often made things more complex and confusing, especially in classroom setting.</p> <p><strong>In version 3.0 the default back-end is “The same interpreter which runs Thonny”</strong> (by the way, this was already the default setting on Raspberry Pi). This means your programs will see all Python packages that are installed to this interpreter. Instructors can now install extra packages to the central interpreter and students will see the packages without any hassle.</p> <p>This change does not mean that I now consider virtual environments unimportant. As a new feature, <strong>Thonny 3.0 offers an easy way for creating and using virtual environments</strong> (Tools → Options → Back-end → Alternative Python 3 interpreter or virtual environment).</p> <p>“A special virtual environment” back-end is still available and if you used it with your older Thonny, then Thonny 3.0 will use it as well. If you are using Thonny+Python bundle, then 3.0 will start by creating new virtual environment, because the one created for Python 3.6 does not work with Python 3.7.</p> </div> <div class="section" id="more-straightforward-user-package-management"> <h2>More straightforward user package management</h2> <p>Now when default back-end is not a virtual environment, how can users install extra packages? In 3.0 the package manager (“Tools → Manage packages…”) installs to user site packages (with <span class="docutils literal"><span class="pre">pip</span> <span class="pre">install</span> <span class="pre">--user</span></span>) when back-end is not a virtual environment. The plug-ins manager always installs to user site packages, unless Thonny itself is run from a virtual environment.</p> <p>You can also install packages outside of Thonny (either with or without <span class="docutils literal"><span class="pre">--user</span></span>) and these will be visible in Thonny.</p> </div> <div class="section" id="basic-micropython-support-built-in"> <h2>Basic MicroPython support built-in</h2> <p><a class="reference external" href="https://thonny.org/blog/2018/06/05/thonny_and_micropython.html">MicroPython plug-ins for Thonny</a> have been available for a while, but so far this topic was kept separate from the main project. Since Thonny 3.0 the core of these plug-ins will be developed and distributed as part of the <span class="docutils literal"><span class="pre">thonny</span></span> package. For the end-user this means that it is possible to program MicroPython devices without installing any extra plug-ins (just select “Tools → Options → Back-end → MicroPython on a generic device”). For more complete support (eg. for installing or updating firmware) there are device-specific plug-ins/back-ends available. See <a class="reference external" href="https://bitbucket.org/plas/thonny/wiki/MicroPython">https://bitbucket.org/plas/thonny/wiki/MicroPython</a> for more info.</p> </div> <div class="section" id="new-windows-installer"> <h2>New Windows installer</h2> <p>This was already introduced in 2.1.21, but let’s repeat it here as well. You can now use Windows installer for installing either for current user or for all users. See the <a class="reference external" href="https://thonny.org/blog/2018/07/25/version_2_1_21.html">2.1.21 announcement</a> for more info.</p> </div> <div class="section" id="themes"> <h2>Themes</h2> <p>In case you missed <a class="reference external" href="https://thonny.org/blog/2018/05/04/version_2_2_0_beta.html">2.2 beta announcement</a> – Thonny now has ability for changing UI and syntax themes (Tools → Options → Theme & Font).</p> </div> <div class="section" id="new-versions-requirements"> <h2>New versions / requirements</h2> <ul class="simple"> <li>Thonny+Python bundles now come with Python 3.7.</li> <li>Python 3.4 is not supported anymore (neither for front-end nor as back-end).</li> <li>Tk 8.5 is not supported anymore.</li> <li>Mac bundle now requires macOS 10.9 or later (because it bundles 64-bit only Python). Note that you can still <span class="docutils literal"><span class="pre">pip</span> <span class="pre">install</span> <span class="pre">thonny</span></span> on older Macs (provided you have <a class="reference external" href="https://www.python.org/download/mac/tcltk/">Python with Tk 8.6</a>).</li> </ul> </div> <div class="section" id="how-to-test-the-beta-without-affecting-your-stable-thonny"> <h2>How to test the beta without affecting your stable Thonny?</h2> <p>If you don’t want to overwrite your current Thonny, then you can <span class="docutils literal"><span class="pre">pip</span> <span class="pre">install</span> <span class="pre">--pre</span> <span class="pre">thonny</span></span> into a virtual environment. Since 3.0, when Thonny is run from a virtual environment, it keeps all user data (eg. configuration.ini) also inside this environment. This way you don’t risk messing up the configuration of your stable Thonny version and you can get rid of the beta just by deleting the virtual environment.</p> </div> <div class="section" id="all-new-features-and-changes-since-2-2b4"> <h2>All new features and changes since 2.2b4</h2> <ul class="simple"> <li>NEW: Thonny now has two debug modes: beside original AST based debug mode (the “nicer” one, Ctrl+F5) there is now also line-based mode (the “faster” one, Shift+F5), which is not so intuitive but much more efficient.</li> <li>NEW: Both debug modes now support breakpoints (switch on line numbers and double-click on the margin)</li> <li>NEW: Alternative presentation for call stack (in single window, just like in most debuggers; see Tools => Options => Debugger)</li> <li>NEW: Clicking on the links in stacktrace now shows the variables of those frames.</li> <li>NEW: You can re-run your changed program without closing it first (relevant for graphical programs).</li> <li>NEW: Checking “Run => Dock user windows” makes your Tkinter windows stay on top and appear always on the same location.

This comes in handy when you are debugging with big steps (step over) and accidentally step over an interesting part in code. Instead of starting from scratch again, you can now issue the command “Run -> Step back” which brings the visual represetation of the program back to the state as it was before last debugger command. From there you can choose to continue with small steps (step into). You can make as many steps back as required and you can go back and forward as many times as you wish.</p> <p>Stepping back was implemented by Alar Leemet as part of his Bachelor thesis. <strong>Please give him <a href="https://goo.gl/forms/huwubX2XQEZRiQC42">feedback about this feature</a></strong>!</p></div> <div class="section" id="b4-2018-06-05"> <h2>2.2.0b4 (2018-06-05)</h2> <ul class="simple"> <li>FIXED: Couldn’t open menus with None backend</li> </ul> </div> <div class="section" id="b3-2018-06-05"> <h2>2.2.0b3 (2018-06-05)</h2> <ul class="simple"> <li>FIXED #425: Too big automatic scaling</li> <li>FIXED #427: Can’t run files with spaces in filename</li> <li>FIXED: Fixed a bug when debugging and encountering an exception (by Alar Leemet)</li> <li>ENHANCEMENT: Show indicator about stepping in the past in the text of editor tabs</li> <li>ENHANCEMENT: Added Thonny version guards for installing plug-ins</li> <li>EXPERIMENTAL: Preliminary support for running system commands in Thonny shell (eg. <cite>!ls</cite> or <cite>!dir</cite>)</li> <li>TECHNICAL: thonny.exe in Windows bundle is now signed</li> <li>TECHNICAL: Delay starting of Runner until UI is shown</li> <li>TECHNICAL: Various enhancements to support MicroPython plug-ins (<a class="reference external" href="https://bitbucket.org/plas/thonny-micropython">https://bitbucket.org/plas/thonny-micropython</a>)</li> </ul> </div> <div class="section" id="b2-2018-05-04"> <h2>2.2.0b2 (2018-05-04)</h2> <ul class="simple"> <li>FIXED: Options dialog crashes when Variables view hasn’t been created yet</li> </ul> </div> <div class="section" id="b1-2018-05-04"> <h2>2.2.0b1 (2018-05-04)</h2> <ul class="simple"> <li>NEW: Added support for stepping back in time during debugging (Run => Step back) by Alar Leemet.
