Re: [Pharo-users] Request for Windows test

by webwarrior

Windows finds DrGeo.exe suspicious. I guess the problem will disappear when enough users have launched it. But it's usable anyway, you just have to click through the annoying dialog. -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Re: [Pharo-users] Zinc + HTTPS does not check for self signed certificates.

by Sven Van Caekenberghe

Hi JuliÃ¡n, Although we have TLS/SSL support (in the form of Zodiac, Zinc is just a user offering HTTP(S) on top), it is currently all dependent on a plugin that is different on all platforms and mostly lacks support for certificates. It is what it is. I know that some developers are working on these issues, but I won't / can't say more as this is all very early days.

Request for Windows test

by Hilaire

Hi, A Windows user reported to me difficulty to start Dr. Geo. Although I had success to run it in a Windows system, I will be glad if some of you would mind testing it on their windows system, and report to me success or failure along the used Windows system. -> http://www.drgeo.eu/download Thanks a lot Hilaire -- Dr. Geo http://drgeo.eu

Tonel class comments

by Guillermo Polito

Hi all, Since people have been asking how to use Tonel, I've took a look at it and have written down two class comments for both the reader and the writer. I'll push them to Tonel and schedule soon a patch release with it. Here are the class comments so people can see them/discusses them. Please, report any enhancements as pull requests in git@github.com:pharo-vcs/tonel.git ! TonelReader I'm a monticello reader for tonel format repositories. I read - a package per directory - a class per file - a set of extensions to a single class per file (for example, all extensions of a package to String will be in a single file) I'm created on a file reference to a directory where the package will be read and the name of the package to read. [[[ TonelReader on: 'someDirectoryWithTonelPackages' asFileReference filename: 'MyPackageName' ]]] My main method is - ==#definitions== reads and parses the tonel file, returns a list of monticello definitions. - ==#snapshot== returns a monticello snapshot with the read definitions. - ==#version== returns a monticello version with the read snapshot. !! Implementation details The monticello versions I return do have artificial information. Since I'm just meant to read versions from a directory, this directory has no information such as commit message, commit time, author, or ancestors. Check the method ==#loadVersionInfo== for more information. ! TonelWriter I'm a monticello writer for tonel format, writing - a package per directory - a class per file - a set of extensions to a single class per file (for example, all extensions of a package to String will be in a single file) I'm created on a file reference to a directory where the package will be written. [[[ TonelWriter on: ('someDirectory' asFileReference ensureCreateDirectory) ]]] My main methods are - ==#writeVersion:== that receives as argument a monticello version to write, from where I'll extract the corresponding monticello snapshot. - ==#writeSnapshot:== that receives as argument a monticello snapshot to write, from where I'll write all the contained definitions. !! Implementation details Notice that while writing, if the written package/snapshot already exists in the directory I'll overwrite it (i.e., remove it and recreate it). -- Guille Polito Research Engineer Centre de Recherche en Informatique, Signal et Automatique de Lille CRIStAL - UMR 9189 French National Center for Scientific Research - *http://www.cnrs.fr <http://www.cnrs.fr>* *Web:* *http://guillep.github.io* <http://guillep.github.io> *Phone: *+33 06 52 70 66 13

There are some individual documents on the subject of XML, but to my knowledge there is no all-encompassing paper that covers everything about XML. E.g. you find a paper about XPath <https://files.pharo.org/books-pdfs/booklet-Scraping/2017-09-29-scrapingbook…>. The author of the XML libraries available in Pharo is Monty and has a blog here: <https://montyos.wordpress.com/>. If you want to delve deeper into the topic, I would read Monty's entries in the Pharo specific mailing lists. I'm sure you can learn a lot here. He is very competent and helpful. <http://forum.world.st/template/NamlServlet.jtp?macro=search_page&node=12947…> searches all entries of monty in the last 600 days. HTH, Franz Josef
