Daily driving Plasma Mobile

Planet KDE - Sat, 2024-05-04 19:00

So, it’s been a while since I’ve last blogged. A lot has happened in the mobile Linux world since I made the post sharing the State of Linux on mobile. We’re 5 years further now, some distro options have disappeared and others have popped up, and although I’ve always been really optimistic about what Linux on mobile promises and can become I’ve never actually used it as my daily driver. Even though I work on postmarketOS and would say I know a fair bit about it’s shortcomings and possibilities, I’ve been relying on an Android phone for all this time to get me through life. And I’ve noticed that this is the case for a lot of people and especially developers in the Linux world.

Recently I decided this should change. How can we ever get Linux on mobile up to a state where we can use it as a proper replacement for the duopoly that is Android and iOS if nobody, including the developers, actually use it even though it’s already out there and available? I’m of course a KDE fan and would love to use Plasma Mobile specifically but it has a ton of papercut issues that could easily be solved if the developers actually noticed them by using it! So about two weeks ago I decided to get myself a new, second-hand, phone to actually daily drive postmarketOS with Plasma Mobile on and I’ll tell you about my experiences with it so far.

My setup

Although a lot of people still seem to think Pine64’s PinePhone (Pro) or Purism’s Librem 5 are the best options for a Linux phone out there, I would argue this is not the case any more. Besides the PinePhone being awfully slow hardware it is suffering from a lack of software support, the kernel is maintained by a single person in their spare time and has a ton of things not actually upstreamed to mainline, and the Librem 5 is way too expensive for what it offers and is made by a company that currently seems to have severe financial problems (they recently layed off most of their developers). Instead I would recommend a well supported (former) Android device, the postmarketOS wiki has a good list of well supported devices and specifically I would recommend getting a SDM845 device, namely the OnePlus 6/6T, SHIFT6mq (you can buy these brand new even) and the Xiaomi Pocophone F1. These are fully mainline supported and are easily buyable second-hand through platforms like eBay for not too much.

I however decided to get a Pixel 3A. This device is also fully mainline supported and I think it’s good to not have all attention focused on a few specific devices but get broader support available. The Pixel 3A was a popular phone when it was still newly sold so a lot of people might actually still have one laying around.

postmarketOS also supports a bunch of tablets which would actually be a really good use-case for Plasma Mobile.

Software

So as I mentioned earlier I’m a KDE fan, so of course I opt to run Plasma Mobile. I maintain a (semi-)nightly repository of all KDE packages that tries to build the entirety of KDE from git master every day. This has been proven very useful for Plasma Mobile development as newly merged changes can be quickly tested by consumers and also reduces the need to compile the entirety of Plasma on your phone if you want to change just a few lines in the code. It was made to support the transitioning to Qt6 but I find it so useful that I’ll keep it around in the future. So on my new phone I enabled this repository, executed the upgrade and rebooted into a fresh Plasma 6 installation straight from git master the day before.

It is good to note that although I’m definitely daily driving postmarketOS now, my sim-card is actually still in my Android phone. I do not currently trust the stability of phone calls, mostly when it comes to audio. We (postmarketOS) are working hard to improve the situation, especially by switching to PipeWire for audio hopefully soon, but for now I’m carrying two devices around having my Android phone share a hotspot to postmarketOS. The camera also currently doesn’t work so for that having the Android phone around for now is also still very useful. The camera however is making good progress with projects like libcamera making it possible to create camera applications and use it in browsers like Firefox.

So, what do I actually use this phone for? These are some of the use-cases I have and the applications I use for them:

  • browsing the web with Angelfish
    • I would actually prefer to use Firefox to not support Google’s monopoly on the web by using a Chromium-based browser but I currently think Angelfish’s experience is better than the Firefox one on mobile
  • make and keep track of notes with Marknote, for example shopping lists
  • watch YouTube with PlasmaTube
  • sync files and pictures from my NextCloud server with GhostCloud
    • I actually used this years ago when I still used SailfishOS. I was very glad to see it’s still around and even supports Ubuntu Touch and regular desktop Linux (and thus Plasma Mobile) as well nowadays. A Kirigami based-UI for this so it fits in better would be nice but it’s very usable as is
  • chat on Matrix with NeoChat
  • listen to my music with Elisa
  • manage my local files with Index
  • manage my calendar with Merkuro
  • do offline turn-by-turn navigation with Osmin
    • I find this application incredible. In my mind navigation is a difficult to create app but Osmin works well and calculates routes very quickly (completely offline!). It’s not yet as feature-full as say OSMand on Android but it’s very usable
  • browse the fediverse (Mastodon) with Tokodon
  • check the weather with KWeather

This actually covers a huge part of what I would do on Android as well, now I just do these on postmarketOS instead using almost exclusively KDE applications! I’m still missing a few (for me) important things, most notably a Keepass-compatible client to get the passwords needed for aforementioned applications. I worked around that however by using KDEConnect to share my clipboard from my desktop where I just use KeepassXC. And of course the few Android applications that just don’t have FOSS-replacements like WhatsApp or my bank app, but I’m hoping either Waydroid or even the in my opinion more promising android-translation-layer (basically Wine for Android apps) can be used for that in the future.

Now although this is a very usable setup for me, when actually using this you’ll quickly notice a lot of small but annoying issues. These are all small in size and would easily be fixed if there were developers to experience them but accumulating together they make the whole experience a bit frustrating still. I’ve been reporting everything I could find so far (for example see all the issues I’ve made on just the Plasma Mobile shell). A few examples:

  • several applications have multiple actions on the same button press, like NeoChat both opening a room and opening a context menu for it when pressing on a room in the room list, BUG: 486545
  • Angelfish automatically switches to a newly opened tab which is unlike any other mobile browser, unexpectedly throwing the user off whatever they’re reading, and shows an unnecessary message telling the user the new tab has been opened which is blocking the button to go back to the previous tab, BUG: 486463
  • QMLKonsole (the mobile alternative to Konsole) for some reason has it’s own button to open and close the keyboard but pressing it has various buggy behaviours, BUG: 355
  • various applications have context hints that are meant to be shown on desktop when hovering an element but show up when pressing buttons or input fields on mobile, BUG: 360
  • various desktop widgets are completely broken, BUG: 354
  • sometimes (not often) the shell just crashes, I haven’t been able to find a good reproducer yet
Development

To a lot of KDE developers developing for Plasma Mobile is an unknown (and possibly scary) territory and they might not know how to do it easily. Will you compile everything on your device or cross-compile from your desktop instead, use kde-builder or do it manually? Of course this all comes down to personal preferences in the end but let me tell you how I do it.

Like I mentioned earlier I’m maintaining a nightly repository shipping the entirety of KDE from git master. I highly recommend using this repository so you can quickly test and use new features and bug fixes. Instructions to set this up are on the postmarketOS wiki.

Although compilation on device (e.g. using kde-builder) is most definitely possible, this is just regular good ol’ Linux after all, it’s a slow process due to the limited performance of a phone and might warm it up more than is safe for the device. Instead I would recommend using the lovely pmbootstrap tool we use for postmarketOS development and build on your way more performant PC instead. This tool builds software using Alpine’s simple APKBUILD format. You don’t have to worry too much about learning this format, these APKBUILDs already exist for basically every KDE package out there and you can just reuse these. After setting up pmbootstrap (pmbootstrap init) you can get such an APKBUILD for a KDE package either by manually downloading it from the upstream repository and placing it in the location pmbootstrap expects or run pmbootstrap aportgen --fork-alpine <package name>. This makes pmbootstrap get the APKBUILD from Alpine Linux and put it in your local checkout of postmarketOS packages.

The APKBUILD just downloaded can be used as is and you can now build the package with pmbootstrap build --arch <CPU architecture of the target device> but you probably want to use your local checkout of the code with your changes instead. For this pmbootstrap supports the --src argument which makes it build the same APKBUILD but with the source replaced for your local checkout. If your changes require any dependencies changed from what is currently provided by the package you can edit either the $makedepends or $depends (build dependencies and runtime dependencies respectively) variables in the APKBUILD ($depends might not exist, just create it if it doesn’t).

When you’ve successfully built the package you can send it to your device using pmbootstrap sideload <package name>. This will send it to a device running postmarketOS and let the packagemanager APK install it. Restart the application in question and your changes will be ready to test! pmbootstrap supports way more fancy features and I recommend you read it’s documentation to see what you can do.

Conclusion

In my opinion Plasma Mobile on postmarketOS is very usable right now but at the moment suffers from a lot of papercuts. I hope that since I now daily drive the system I can find all these papercuts, report them and possibly even fix one or two of them. But even more so I hope I can convince KDE developers to pick up a phone themselves and start using the system they’re in fact already developing for (95% of the Plasma Mobile stack is the same as Plasma Desktop and all the applications used were made to be used on desktop as well!). The system has a lot of potential and is already great to use, it just needs developers! Get a cheap second hand phone, flash postmarketOS on it and start using it!

I’m dreaming of a day where I’m not the only one at Akademy that not only has Plasma on their laptop but also their phone!

Sven Hoexter: vym - view your mind

Planet Debian - Sat, 2024-05-04 10:59

Had a need for a mindmapping application and found view your mind in the archive. Works but the version is a bit rusty. Sadly my Debian packaging skills are a bit rusty as well, especially when it comes to bigger GUI applications. Thus I spent a good chunk of yesterday afternoon to rip out cdbs and package the last source release on github which is right now 2.9.22 (the release branch already has 2.9.27, still sorting that out).

Git repository and a amd64 build of the current state. It still deserves some additional love, e.g. creating a -common package for arch indep content.

Proposed a few changes upstream:

Also pinged pollux@ who uploaded vym up to 2019 if he'd be fine if I pick it up. If someone else is interested, I'm also fine to put it up on salsa in the general "Debian" group for shared maintenance. I guess I will use it in the future, but time is still a scarce resource for all of us.

Send your talks for Akademy NOW!

Planet KDE - Sat, 2024-05-04 06:35

Akademy 2024 (the annual world summit for KDE) is happening in Würzburg, Saturday 7th – Thursday 12th September. (I hope you knew that)


First of all, if you're reading this and thinking, "Should i go to Akademy?" 


The answer is [most probably] YES! Akademy has something for everyone, be it coders, translators, promoters, designers, enthusiasts, etc.


Now, with this out of the way, one of the many things that makes Akademy is the talks on the weekend, and you know who has something to say? *YOU*


Yes, *YOU*. I'm sure you've been working on something interesting, or have a great idea to share.


*YOU* may think that your idea is not that great or the things you work on are not interesting, but that's seldomly the case when someone explains me their "boring" thing they've been working on, i always think "Wow that's great".


Ok, so now that I've convinced you to send a talk proposal, when better than *TODAY* to send it?


Yes I know the Call for Participation is open until the 24 of May, but by sending it today you make sure you don't forget sending it later and also [more important for me] you help those of us in the Program Committee not when the final date starts approaching and we don't have lots of talks yet because you all prefer sending talks on the very last minute.


So stop reading and send your talk today ;-)

This week in KDE: Looking towards Plasma 6.1

Planet KDE - Sat, 2024-05-04 00:57

This week we put some of the final Plasma 6.0 bugs to rest, and continued working towards Plasma 6.1 with a variety of UI improvements. Nothing ground-breaking this week, just a slow grind of useful work towards a solid release!

UI Improvements

Kate now considers a file as recent when it’s saved or closed, not just when it’s opened. This means your recent files list will no longer omit files you kept open for a long time while working on them (Christoph Cullmann, Kate 24.05. Link)

The panel icons for Kickoff (Application Launcher) and Kicker (Application Menu) widgets are now capped in size so they can’t grow ridiculously huge on thicccc panel (Akseli Lahtinen and me: Nate Graham, Plasma 6.0.5. Link 1 and link 2)

System Settings no longer lets you choose GNOME’s Adwaita or High Contrast icon themes as your systemwide icon theme, because despite registering themselves as FreeDesktop-compatible icon themes, they are no longer actually designed to be used this way and will break everything from KDE if you try anyway (me: Nate Graham, Plasma 6.0.5. Link)

The screen that KWin considers active for the purpose of determining which screen to open new windows on is now determined by “last user interaction”, which includes things like mouse movement and keyboard focus. Hopefully this should better match people’s expectations (Xaver Hugl, Plasma 6.1. Link)

Made the wallpaper chooser views frameless, matching the current styling of most other settings pages in System Settings and Plasma (me: Nate Graham, Plasma 6.1. Link 1 and link 2):

Plasma’s notifications now use a more appropriate icon for canceling jobs, and also elide long title text in the middle rather than on the left (Ivan Tkachenko, Plasma 6.1. Link 1 and link 2):

Ok, so maybe “plasma-brows…gration-host” is not a work of towering genius. The fact that a long ugly technical name is shown there is another bug we’ll investigate.

Refined the UI shown when changing global themes to make it clear what will happen and what’s potentially dangerous (me: Nate Graham, Plasma 6.1. Link 1 and link 2):

https://i.imgur.com/626VvQ2.mp4

When you use the command-line powerprofilesctl tool to change power profiles, the new state is now reflected in the Power and Battery widget (Natalie Clarius, Plasma 6.1. Link)

Several Breeze icons (folder-encrypted, folder-decrypted, and folder-music) now have proper symbolic versions at their 16px and 22px sizes (me: Nate Graham, Frameworks 6.2. Link)

Bug Fixes

Gwenview no longer fails to open large images; now its Qt 6 version can open the same size of image that the Qt 5 version could (Méven Car, Gwenview 24.05. Link)

On Wayland, KWin no longer crashes when it’s unable to open a socket to XWayland for some reason (Vlad Zahorodnii, Plasma 6.0.5. Link)

Fixed a case where Plasma could crash while modifying the set of favorite apps in Kickoff (Application Launcher), Kicker (Application Menu), or another launcher menu using the same backend infrastructure (Fushan Wen, Plasma 6.0.5. Link)

When using Qt 6.7, the System Tray popup is no longer sometimes inappropriately resized to a tiny nub, and also clicking a System Monitor widget showing GPU sensors no longer causes Plasma to freeze (Marco Martin, Plasma 6.0.5. Link 1 and link 2)

Fixed an extremely strange issue that could be triggered by opening any windows of IntelliJ IDE apps, and would cause other windows and Plasma panels to become transparent to clicks (Vyacheslav Mayorov, Plasma 6.0.5. Link)

When waking the system from sleep, quick-tiled windows no longer sometimes disappear, and vertically-maximized windows are no longer sometimes mis-positioned (Xaver Hugl, Plasma 6.0.5. Link 1 and link 2)

On X11, forcing tablet mode on when using a multi-screen setup with global scaling no longer causes one of the screens to scale everything incorrectly (Xaver Hugl, Plasma 6.0.5 Link)

Applied a workaround in KWin for an AMD GPU driver bug, which should reduce instances of random visual glitchiness (Xaver Hugl, Plasma 6.1. Link)

Fixed another case of Korners, this time for menus in QtWidgets-based apps (Ivan Tkachenko, Plasma 6.1. Link)

Resizing a window with a wallpaper chooser grid in it no longer sometimes causes the grid view’s header to disturbingly detach and appear in the middle of the view (me: Nate Graham, Plasma 6.1. Link)

More audio and video files now have appropriate icons, and when no suitable format-specific icon is found, the system will no longer fall back to an inappropriate symbolic speaker or filmstrip icon (Kai Uwe Broulik and me: Nate Graham, Frameworks 6.2. Link 1 and link 2)

Fixed a case in Kirigami where some UI elements would have incorrect colors when using mixed light/dark color schemes (Evgeniy Harchenko, Frameworks 6.2. Link)

After we fixed the “Pick your installation option popup” in the “Get new [thing]” windows, Qt 6.7 broke it again, so we fixed it again! This time moar betterer (Akseli Lahtinen and Ivan Tkachenko, Frameworks 6.3. Link)

Fixed an issue that caused apps with System Tray icons to inappropriately quit when deleting their tray icons (Tor Arne, Qt 6.7.2. Link)

Other bug information of note:

Performance & Technical

Implemented a bunch of security hardening for our crash reporting system based on feedback from SUSE’s security team (Harald Sitter, Plasma 6.0.5. Link)

Automation & Systematization

Added multiple autotests to ensure that mounting different types of mountable filesystems works as intended (Stefan Brüns, Frameworks 6.2. Link)

Added an autotest to make sure that Plasma-themes UI elements that should have the same height—such as text fields and buttons—still do even if the Plasma style is changed (Fushan Wen, Plasma 6.1. Link)

How You Can Help

The KDE organization has become important in the world, and your time and labor have helped to bring it there! But as we grow, it’s going to be equally important that this stream of labor be made sustainable, which primarily means paying for it. Right now the vast majority of KDE runs on labor not paid for by KDE e.V. (the nonprofit foundation behind KDE, of which I am a board member), and that’s a problem. We’ve taken steps to change this with paid technical contractors—but those steps are small due to growing but still limited financial resources. If you’d like to help change that, consider donating today!

Otherwise, visit https://community.kde.org/Get_Involved to discover other ways to be part of a project that really matters. Each contributor makes a huge difference in KDE; you are not a number or a cog in a machine! You don’t have to already be a programmer, either. I wasn’t when I got started. Try it, you’ll like it! We don’t bite!

Trey Hunner: Installing a custom Python build with pyenv

Planet Python - Sat, 2024-05-04 00:26

I am so excited about the new Python REPL that will likely land in Python 3.13. I’ve been following this CPython pull request since I heard Pablo and Łukasz announce their work on the new Python REPL in episode 1 of their new core.py podcast.

Github notifications? 🤔

That pull request was quiet for many months, but in the last couple weeks, I started seeing email notifications in my inbox about it. I’ve never fancied myself a competent C developer and I try to steer clear from understanding TTY magic, so I have no idea what most of the commits do. But seeing activity on this pull request rejuvenated my excitement about this upcoming feature!

I also remember reading that the Python 3.13 feature freeze is coming up soon, so I’ve been silently cheering for that PR to make the cut before the deadline.

In the last few days, I decided that I should try committing to use this new REPL locally as my default Python environment. When I type python on my machine, I want to live in this new shiny REPL. I figure this will make it easier to spot bugs that might not have been noticed yet… though honestly it’ll mostly just allow me to try out this fancy new REPL first-hand.

Installing a custom CPython build in pyenv

I use pyenv to manage the many Python versions I have installed on my machine. I wondered whether it was possible to install a custom build of CPython with pyenv.

Instead of going to the pyenv documentation to figure out an answer, I argued with an AI until it gave me a working answer. I tried a few AI systems at first, but Claude seemed to give me the most promising-looking answer so it was the one I argued with for 5-10 minutes until I got a working solution.

First, I created this ~/.pyenv/plugins/python-build/share/python-build/3.13.0-pyrepl file:

1 2 3 prefer_openssl11 export PYTHON_BUILD_CONFIGURE_WITH_OPENSSL=1 install_package "pyrepl" "https://github.com/pablogsal/cpython/archive/pyrepl.tar.gz" standard verify_py39 ensurepip

Then I ran this command, which took a couple minutes:

1 $ pyenv install 3.13.0-pyrepl

After that, pyenv versions showed a new 3.13.0-pyrepl version:

1 2 3 4 5 6 7 8 $ pyenv versions system * 3.8.18 (set by /home/trey/.pyenv/version) * 3.9.18 (set by /home/trey/.pyenv/version) * 3.10.13 (set by /home/trey/.pyenv/version) * 3.11.6 (set by /home/trey/.pyenv/version) * 3.12.0 (set by /home/trey/.pyenv/version) 3.13.0-pyrepl

I then added 3.13.0-pyrepl to the top of my ~/.pyenv/version file to make this my default Python:

1 2 3 4 5 6 3.13.0-pyrepl 3.12.0 3.11.6 3.10.13 3.9.18 3.8.18

And it worked! Tying python showed the new colorful prompt.

Is is a bad idea to make this not-even-beta version of CPython the default Python on my machine? I have no idea. Everything’s been fine for the last 10 hours at least… 🤷

If you ever need to try installing a custom CPython build with pyenv, maybe the above instructions will work. They’re mostly generated by a large language model that didn’t give me a working answer until the third response… so feel free to let me know if it’s all wrong (or all right?).

After this adventure, I checked my podcast feed this evening only to realize that there’s a new core.py episode all about exactly this feature! If you’d like to hear some core developers nerd out about CPython development, give core.py a listen. You don’t need to understand how CPython development works to enjoy their enthusiasm. 💖

Interview on Tech Over Tea about KDE’s position in the world

Planet KDE - Fri, 2024-05-03 21:46

I recently went on Brodie Robertson’s Tech Over Tea channel for a second time. I guess I didn’t succeed at pissing him off enough on the first go-around, because he invited me back! Let’s see if I did a better job of it this time by telling him he was using Arch wrong.

Anyway, Brodie was a fantastic host, and we talked about a number of topics such as KDE’s position in the world, institutional continuity, fundraising and financial stability, the difficulty of reporting and triaging bug, the challenges of packaging software, and windows that block WiFi signals.

I hope you enjoy it!

And here’s the link I mention at the end: https://kde.org/community/donations

scikit-learn: Note on Inline Authorship Information in scikit-learn

Planet Python - Fri, 2024-05-03 20:00
Author: Adrin Jalali

Historically, scikit-learn’s files have included authorship information similar to the following format:

# Authors: Author1, Author2, ... # License: BSD 3 clause

However, after a series of discussions which you can see in detail in this issue, we could list the following caveats to the status quo:

  • Authorship information was not up-to-date and in most cases, but not always, reflect the original authors of the file;
  • It was unfair to all other contributors who have been contributing to the code-base;
  • One can check the real authors and the history of the authors of any part of the code-base using git blame and other git tools.

Therefore we came to the conclusion to standardize all authorship information to mention “The scikit-learn developers”, and have the license notice as:

# Authors: The scikit-learn developers # License: BSD-3-Clause

The change is to happen gradually in the coming months after April 2024.

Joachim's blog: Refactoring with Rector

Planet Drupal - Fri, 2024-05-03 16:47

Rector is a tool for making changes to PHP code, which powers tools that assist with upgrading deprecated code in Drupal. When I recently made some refactoring changes in Drupal Code Builder, which were too complex to do with search and replace regexes, it seemed like a good opportunity to experiment with Rector, and learn a bit more about it.

Besides, I'm an inveterate condiment-passer: I tend to prefer spending longer on a generalisation of a problem than on the problem itself, and the more dull the problem and the more interesting the generalisation, the more the probability increases.

So faced with a refactoring from this return from the getFileInfo() method:

return [ 'path' => '', 'filename' => $this->component_data['filename'], 'body' => [], 'merged' =>$merged, ];

to this:

return new CodeFile( body_pieces: $this->component_data['filename'], merged: $merged, );

which was going to be tedious as hell to do in a ton of files, obviously, I elected to spend time fiddling with Rector.

The first thing I'll say is that the same sort of approach as I use with migrations works well: work with a small indicative sample, and iterate small changes. With a migration, I will find a small number of source rows which represent different variations (or if there is too much variation, I'll iterate the iteration multiple times). I'll run the migration with just those sources, examine the result, make refinements to the migration, then roll back and repeat.

With Rector, you can specify just a single class in the code that registers the rule to RectorConfig in the rector.php file, so I picked a class which had very little code, as the dump() output of an entire PHP file's PhpParser analysis is enormous.

You then use the rule class's getNodeTypes() method to declare which node types you are interested in. Here, I made a mis-step at first. I wanted to replace Array_ nodes, but only in the getFileInfo() method. So in my first attempt, I specified ClassMethod nodes, and then in refactor() I wrote code to drill down into them to get the array Array_ nodes. This went well until I tried returning a new replacement node, and then Rector complained, and I realised the obvious thing I'd skipped over: the refactor() method expects you to return a node to replace the found node. So my approach was completely wrong.

I rewrote getNodeTypes() to search for Array_ nodes: those represent the creation of an array value. This felt more dangerous: arrays are defined in lots of places in my code! And I haven't been able to see a way to determine the parentage of a node: there do not appear to be pointers that go back up the PhpParser syntax tree (it would be handy, but would make the dump() output even worse to read!). Fortunately, the combination of array keys was unique in DrupalCodeBuilder, or at least I hoped it was fairly unique. So I wrote code to get a list of the array's keys, and then compare it to what was expected:

foreach ($node->items as $item) { $seen_array_keys[] = $item->key->value; } if (array_intersect(static::EXPECTED_MINIMUM_ARRAY_KEYS, $seen_array_keys) != static::EXPECTED_MINIMUM_ARRAY_KEYS) { return NULL; }

Returning NULL from refactor() means we aren't interested in this node and don't want to change it.

With the arrays that made it through the filter, I needed to make a new node that's a class instantiation, to replace the array, passing the same values to the new statement as the array keys (mostly).

Rector's list of commonly used PhpParser nodes was really useful here.

A new statement node is made thus:

use PhpParser\Node\Name; use PhpParser\Node\Expr\New_; $class = new Name('\DrupalCodeBuilder\File\CodeFile'); return new New_($class);

This doesn't have any parameters yet, but running Rector on this with my sample set showed me it was working properly. Rector has a dry run option for development, which shows you what would change but doesn't write anything to files, so you can run it over and over again. What's confusing is that it also has a cache; until I worked this out I was repeatedly confused by some runs having no effect and no output. I have honestly no idea what the point is of caching something that's designed to make changes, but there is an option to disable it. So the command to run is: $ vendor/bin/rector --dry-run --clear-cache. Over and over again.

Once that worked, I needed to convert array items to constructor parameters. Fortunately, the value from the array items work for parameters too:

use PhpParser\Node\Arg; foreach ($node->items as $array_item) { $construct_argument = new Arg( $array_item->value, );

That gave me the values. But I wanted named parameters for my constructor, partly because they're cool and mostly because the CodeFile class's __construct() has optional parameters, and using names makes that simpler.

Inspecting the Arg class's own constructor showed how to do this:

use PhpParser\Node\Arg; use PhpParser\Node\Identifier; $construct_argument = new Arg( value: $array_item->value, name: new Identifier($key), );

Using named parameters here too to make the code clearer to read!

It's also possible to copy over any inline comments that are above one node to a new node:

// Preserve comments. $construct_argument->setAttribute('comments', $array_item->getComments());

The constructor parameters are passed as a parameter to the New_ class:

return new New_($class, $new_call_args);

Once this was all working, I decided to do some more refactoring in the CodeFile class in DrupalCodeBuilder. The changes I was making with Rector made it more apparent that in a lot of cases, I was passing empty values. Also, the $body parameter wasn't well-named, as it's an array of pieces, so could do with a more descriptive name such as $body_pieces.

Changes like this are really easy to do (though by this point, I had made a git repository for my Rector rule, so I could make further enhancements without breaking what I'd got working already).

foreach ($node->items as $array_item) { $key = $array_item->key->value; // Rename the 'body' key. if ($key == 'body') { $key = 'body_pieces'; }

And that's my Rector rule done.

Although it's taken me far more time than changing each file by hand, it's been far more interesting, and I've learned a lot about how Rector works, which will be useful to me in the future. I can definitely see how it's a very useful tool even for refactoring a small codebase such as DrupalCodeBuilder, where a rule is only going to be used once. It might even prompt me to undertake some minor refactoring tasks I've been putting off because of how tedious they'll be.

What I've not figured out is how to extract namespaces from full class names to an import statement, or how to put line breaks in the new statement. I'm hoping that a pass through with PHP_CodeSniffer and Drupal Coder's rules will fix those. If not, there's always good old regexes!

Colin Watson: Playing with rich

Planet Debian - Fri, 2024-05-03 11:09

One of the things I do as a side project for Freexian is to work on various bits of business automation: accounting tools, programs to help contributors report their hours, invoicing, that kind of thing. While it’s not quite my usual beat, this makes quite a good side project as the tools involved are mostly rather sensible and easy to deal with (Python, git, ledger, that sort of thing) and it’s the kind of thing where I can dip into it for a day or so a week and feel like I’m making useful contributions. The logic can be quite complex, but there’s very little friction in the tools themselves.

A recent case where I did run into some friction in the tools was with some commands that need to present small amounts of tabular data on the terminal, using OSC 8 hyperlinks if the terminal supports them: think customer-related information with some links to issues. One of my colleagues had previously done this using a hack on top of texttable, which was perfectly fine as far as it went. However, now I wanted to be able to add multiple links in a single table cell in some cases, and that was really going to stretch the limits of that approach: working out the width of the displayed text in the cell was going to take an annoying amount of bookkeeping.

I started looking around to see whether any other approaches might be easier, without too much effort (remember that “a day or so a week” bit above). ansiwrap looked somewhat promising, but it isn’t currently packaged in Debian, and it would have still left me with the problem of figuring out how to integrate it into texttable, which looked like it would be quite complicated. Then I remembered that I’d heard good things about rich, and thought I’d take a look.

rich turned out to be exactly what I wanted. Instead of something like this based on the texttable hack above:

import shutil from pyxian.texttable import UrlTable termsize = shutil.get_terminal_size((80, 25)) table = UrlTable(max_width=termsize.columns) table.set_deco(UrlTable.HEADER) table.set_cols_align(["l"]) table.set_cols_dtype(["u"]) table.add_row(["Issue"]) table.add_row([(issue_url, f"#{issue_id}")] print(table.draw())

… now I can do this instead:

import rich from rich import box from rich.table import Table table = Table(box=box.SIMPLE) table.add_column("Issue") table.add_row(f"[link={issue_url}]#{issue_id}[/link]") rich.print(table)

While this is a little shorter, the real bonus is that I can now just put multiple [link] tags in a single string, and it all just works. No ceremony. In fact, once the relevant bits of code passed type-checking (since the real code is a bit more complex than the samples above), it worked first time. It’s a pleasure to work with a library like that.

It looks like I’ve only barely scratched the surface of rich, but I expect I’ll reach for it more often now.

Python Engineering at Microsoft: Python in Visual Studio Code – May 2024 Release

Planet Python - Fri, 2024-05-03 10:44

We’re excited to announce the May 2024 release of the Python and Jupyter extensions for Visual Studio Code!

This release includes the following announcements:

  • “Implement all inherited abstract classes” code action
  • New auto indentation setting
  • Debugpy removed from the Python extension in favor of the Python Debugger extension
  • Socket disablement now possible during testing
  • Pylance performance updates

If you’re interested, you can check the full list of improvements in our changelogs for the Python, Jupyter and Pylance extensions.

“Implement all inherited abstract classes” Code Action

Abstract classes serve as “blueprints” for other classes and help build modular, reusable code by promoting clear structure and requirements for subclasses to adhere to. To define an abstract class in Python, you can create a class that inherits from the ABC class in the abc module, and annotate its methods with the @abstractmethod decorator. Then, you can create new classes that inherit from this abstract class, and define an implementation for the base methods. Implementing these classes is easier with the latest Pylance pre-release! When defining a new class that inherits from an abstract one, you can now use the “Implement all inherited abstract classes” Code Action to automatically implement all abstract methods and properties from the parent class:

New auto indentation setting

Previously, Pylance’s auto indentation behavior was controlled through the editor.formatOnType setting, which used to be problematic if one would want to disable auto indentation, but enable format on type through other supported tools. To solve this problem, Pylance’s latest pre-release now has its own setting to control auto indentation behavior, python.analysis.autoIndent, which is enabled by default.

Debugpy removed from the Python extension in favor of the Python Debugger extension

In our February 2024 release blog, we announced moving all debugging functionality to the Python Debugger extension, which is installed by default alongside the Python extension. In this release, we have removed duplicate debugging code from the Python extension, which helps to decrease the extension download size. As part of this change, "type": "python" and "type": "debugpy" specified in your launch.json configuration file are both interpreted as references to the Python Debugger extension path. This ensures a seamless transition without requiring any modifications to existing configuration files to run and debug effectively. Moving forward, we recommend using "type": "debugpy" as this directly corresponds to the Python Debugger extension which provides support for both legacy and modern Python versions.

Socket disablement now possible during testing

You can now run tests with socket disablement from the testing UI. This is made possible by a switch in the communication between the Python extension and the test run subprocess to now use named-pipes as opposed to numbered ports. This feature is available on the Python Testing Rewrite, which is rolled out to all users by default and will soon be fully adopted in the Python extension.

Pylance Performance

The Pylance team has been receiving feedback that Pylance’s performance has degraded over the past few releases. As a result, we have made several smaller improvements to memory consumption and indexing including:

  • Improved performance for third-party packages indexing
  • Skipped Python files from workspace .conda environments from being scanned (@pylance-release#5191)
  • Skipped index on unnecessary py.typed file checks (@pyright#7652)
  • Reduced memory consumption by refactoring tokenizer and parser output (@pyright#7602)
  • Improved memory consumption for token creation (@pyright#7434)

For those who may still be experiencing performance issues with Pylance, we are kindly requesting for issues to be filed through the Pylance: Report Issue command from the Command Palette, ideally with logs, code samples and/or the packages that are installed in the working environment.

Additionally, we have added a couple of features in the latest Pylance pre-release version to help identify potential performance issues and gather additional information about issues you are facing. There is a new notification that prompts you to file an issue in the Pylance repo when the extension detects there may be a performance issue. Moreover, Pylance now provides a profiling command Pylance: Start Profiling that generates cpuprofile for all worker threads. This file is generated after starting and stopping profiling by triggering the Pylance: Start Profiling and Pylance: Stop Profiling commands and can be provided as additional data in an issue.

With these smaller improvements and additional ways to report performance issues, we hope to continue to make improvements to performance. We greatly appreciate the feedback and collaboration as we work to address issues!

Other Changes and Enhancements

We have also added small enhancements and fixed issues requested by users that should improve your experience working with Python and Jupyter Notebooks in Visual Studio Code. Some notable changes include:

  • Test Explorer displays projects using testscenarios with unittest and parameterized tests inside nested classes correctly (@vscode-python#22870).
  • Test Explorer now handles tests in workspaces with symlinks, specifically workspace roots which are children of symlink-ed paths, which is particularly helpful in WSL scenarios (@vscode-python#22658).

We would also like to extend special thanks to this month’s contributors:

Call for Community Feedback

As we are planning and prioritizing future work, we value your feedback! Below are a few issues we would love feedback on:

Try out these new improvements by downloading the Python extension and the Jupyter extension from the Marketplace, or install them directly from the extensions view in Visual Studio Code (Ctrl + Shift + X or ⌘ + ⇧ + X). You can learn more about Python support in Visual Studio Code in the documentation. If you run into any problems or have suggestions, please file an issue on the Python VS Code GitHub page.

The post Python in Visual Studio Code – May 2024 Release appeared first on Python.
