You are trying to load Tonel but not telling Metacello where to load it from: Metacello new repository: 'github://pharo-vcs/tonel'; baseline: 'Tonel'; load.

Re: [Pharo-users] A playground for Markdown?

by Dimitris Chloupis

For me Pillar has been the most underused feature of Pharo by far and it makes me sad how little we take advantage of this great technology. Pillar provides a feature set far longer and more important than markdown but I think as a community we need to not only include Pillar inside our standard distribution but built Pharo around it because itâs the perfect nerve center that unites so many massively popular documentation technologies like Markdown , LaTex, PDF and the usual suspect HTML. The features are there. The only thing remaining is people using them.

A playground for Markdown?

by Offray Vladimir Luna CÃ¡rdenas

Hi, Playgrounds are a really good way to write short snippets of code and I wonder if such experience could be extended for larger pieces of Markdown. What I'm thinking of is have something similar butÂ like this: 1. Support for Markdown instead of Smalltalk, including syntax hightlighning and tab behavior (a tab equals two spaces). 2. Clicking on urls should load the respective web page. Clicking on images shouldÂ show an image preview. That's it, to start with. At some point it could be using GT Documenter previews, font support and so on. But I would like to start by extending the playground to just support this two features. Any advice about where can I start for the first feature? Thanks, Offray

Problem fetching a baseline

by Vitor Medina Cruz

Hello, I am experimenting with Metacello but I am having problems to test my configuration. First I thought the problem was with my configuration, but after serveral atemps I tried to fetch an arbitrary Baseline from default image: Metacello new className: 'BaselineOfTonel'; baseline: 'Tonel'; fetch. And I got the following error: "Could not resolve: BaselineOfTonel [BaselineOfTonel] in C:\Users\Vitor\Documents\Pharo\images\Pharo 6.1 (stable)\pharo-local\package-cache http://smalltalkhub.com/mc/Pharo/MetaRepoForPharo30/main/" Which is the same I got with my own project. I tried using 'repository:' also, but got the same error. Am I doing something wrong? cheers, Vitor. <http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_cam…> Livre de vÃrus. www.avg.com <http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_cam…>. <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2>

Re: [Pharo-users] Running headless on Windows

by Torsten Bergmann

Hi, (cross posting vm-dev) nssm is nice - but requires additional tools. Since the days of Squeak the windows VM had the -service "ServiceName" option and one was able to run Squeak as a windows service out of the box. See http://wiki.squeak.org/squeak/105 for details. This option allows to register/deregister with the windows service manager and run a headless image. I run a Squeak Wiki (Swiki/Comanche) since years with this and it is very nice and stable. Unfortunately this is broken in recent Pharo VMs and so far Esteban or others did not have the time to look into this issue. Would be really nice if this option could be recovered in 2018. So one could easily deploy and run Seaside or Teapot/Tealight or Zinc/WebClient based web services on Windows. If we want to deploy Smalltalk based web applications or services on Windows we should support that. It will keep Windows administrators happy and we would integrate with the whole ecosystem (for instance you can start/stop a service using Windows scripting for doing backups, etc.) right out of the box.
