Purr Data 2.5.0

@jancsika , I installed Purr data 2.5.1 via agraef PPA in Xubuntu 18.04 and Ubuntu 18.04 LTS, in all two instalations I have visual glitches with all fonts:

Can I make something to solve this little anoying issue?

Thanks a lot for your work!!

Purr Data and Fedora 26 (again)

@brendanmac Fedora uses its own package format called RPM.

I usually don't get involved in distro wars. But unless there is a requirement that you use Fedora I would strongly suggest using a distro like Ubuntu. It doesn't use RPM packages but instead uses so-called "deb" packages. It has more documentation, a greater variety of users (non-technically and technical users), and it is geared toward new Linux users.

You've already hit installation bugs with both Purr Data and Pd Vanilla. Fedora is a great distro, but for small software projects like Pd you are much more likely to find support, documentation, and ease-of-use in an apt-based distro like Ubuntu (or Debian, or Linux Mint, or any other distro that uses "deb" packages). Problems like these are going to quickly pile up as you try out various Linux audio programs because those maintainers don't have time to create and maintain an RPM in addition to deb packages. (And deb is by far the more popular package format.)

Just to give you an example-- without any coordination whatsoever Albert Graef swooped in and started an Ubuntu "PPA" for Purr Data (which-- again-- uses "deb" packages). That means you can install Purr Data on a stable version of Ubuntu and get Purr Data updates whenever you update the system. Alternatively, nobody has touched the old Pd-extended RPM for years.

I use Debian and Ubuntu. IOhannes is a Debian member and maintains deb packages for Pd Vanilla. Use a "deb"-based distro like Ubuntu and you'll have a much easier Linux experience. :

Font issue with new linux distros

Not sure if it's related but we ran into some font engine problems in Purr Data last year that showed up in ubuntu 16.04.

Apparently somebody somewhere in the Gnu font stack "fixed" font-rendering such that a monospaced font like DejaVu Mono got rendered with a measurable difference in width compared to OSX, Windows, and every earlier Gnu font stack I could check.

Here's my comment about it in the Purr Data workaround:

+var font_engine_sanity;
+
+// Here we use an HTML5 canvas hack to measure the width of
+// the text to check for a font rendering anomaly. Here's why:
+//
+// It was reported that Ubuntu 16.04, Arch-- and probably most other Gnu/Linux
+// distros going forward-- all end up with text extending past the box border.
+// The test_text below is the string used in the bug report.
+// OSX, Windows, and older Gnu/Linux stacks (like Ubuntu 14.04) all render
+// this text with a width that is within half a pixel of each other (+- 217).
+//
+// Newer versions of Ubuntu and Arch measured nearly 7 pixels wider.
+//
+// I don't know what the new Gnu/Linux stack is up to (and I don't have the
+// time to spelunk) but it's out of whack with the rest of the desktop
+// rendering engines. Worse, there's some kind of quantization going on that
+// keeps the new Gnu/Linux stack from hitting anything close to the font
+// metrics of Pd Vanilla.
+//
+// Anyhow, we check for the discrepancy and try our best not to make newer
+// versions of Gnu/Linux distros look too shitty...

In Purr Data, systems using this new font stack will notice a small amount of extra padding at the right of the box. This is because as I mentioned the font engine quantizes the pixel font size such that fitting it to the box makes it slightly smaller than what would be ideal. Rather than making the box smaller, I purposefully keep the box size consistent across all platforms so that users on Ubuntu 16.04 and greater don't end up putting boxes so close to each other that they end up overlapping when viewed on Windows/OSX.

Hope that helps.

Uninstall from Ubuntu 16.04

@EEight It doesn't work, because it says that "El paquete «puredata» no está instalado", that puredata is not installed... isn't it rare?

anibal@anibal-ubuntu:~$ sudo apt-get purge pd

Then I did:

...and I launched pd fine... The puredata-core corresponded to an earlier installation. Thanks!
