Thank you for the tip. I'll try it to learn something new, although Pablo answered for concrete issue. Sincerely, Gour -- The intricacies of action are very hard to understand. Therefore one should know properly what action is, what forbidden action is, and what inaction is.

Adding my ~/.fonts solves it, but I've to install absolute path and wonder how it should work with a relative one, iow. '~/.fonts' ?

Which 'Update' button do you refer to? Very generally, to add in logging... Bring up the "halos" of that button, drilling in a few times to get to the PluggableButtonMorph [1], then click the Debug(wrench)halo-icon and Inspect Morph.

It seems that the directory lookup process is wrong, the directories are having less entries. If you check the class FreeTypeFontProvider has the methods to resolve the directories. You can change the implementation of #unixFontDirectories to add the missing directory, I will file an issue in fogbuz. Cheers.

It lists ~/.fonts, but Pharo tool does not see those fonts. Is there a way to log output when I press 'Update'? I see that it scans e.g. /usr/share/fonts, but would like to see complete output?

[ANN] TaskIt v0.2

by Guille Polito

Hi all, With Santi we wanted to share a new release of TaskIt, a concurrency management library for Pharo. TaskIt development is done entirely in github, using iceberg. Works like a charm. Please find below attached the changes log with more information. Cheers, Guille & Santi TaskIt https://github.com/sbragagnolo/taskit TaskIt is a library that ease Process usage in Pharo. It provides abstractions to execute and synchronize concurrent tasks, and several pre-built mechanisms that are useful for many application developers. This chapter explores starts by familiarizing the reader with TaskIt's abstractions, guided by examples and code snippets. At the end, we discuss TaskIt extension points and possible customizations. ChangesLog TaskIt v0.2 Major Features * Task Runners o NewProcessTaskRunner o LocalProcessTaskRunner o Worker o WorkerPool * Futures with callbacks * Future combinators * Future synchronous access * Services Infrastructure * Travis CIhttps://travis-ci.org/sbragagnolo/taskit * Documentationhttps://github.com/sbragagnolo/taskit/blob/master/README.md Minor changes log (from commits) * Enhanced class comments * TKTWorker processes are terminated in case the worker is collected. See Issues#8 <https://github.com/sbragagnolo/taskit/issues/8>and#5 <https://github.com/sbragagnolo/taskit/issues/5> * Process Dashboard. - Adds TKTTaskItProcessProvider by default with the extension package - Hides job and task fields since there are not reachable any more.

Hi, sometimes running fc-cache is needed to update the FreeTypeFonts caches of fonts. Try just running in your terminal fc-cache It will list all the directories where is looking for classes and updates all the caches, It maybe take some minutes to run, but is needed if you added fonts in the different directories.

Pharo has traditionally been very stable of Windows - but Pharo 5 had a major change to move to the Spur VM and change in FFI, so perhaps there are some things to iron out.

Do not use git. Let us make sure that everything is working well. We manage moose many many package with MC and pharo itself with Monticello and it works. > 1- Shouldn't I be using Windows?

We manage moose many many package with MC and Pharo itself on SmalltalkHub so it is working. It has some glitches but overall it works and it is reliable.
