Is there an interest for working with QT from Pharo ? I make no promises just something I was interested in trying.

Hello Torsten Tealight installs very fine into the latest Pharo release (6.0 / 6.1). It is easy to use and the documentation is great! --Hannes On 8/15/17, Torsten Bergmann <astares(a)gmx.de> wrote: > Hi sergio, > > why not use my existing "Tealight" project which is (similar to Teapot) also > available from Pharo catalog. > It is still lightweight as it is just a few extensions to Teapot. > > You will find it here: > > https://github.com/astares/Tealight > > the page includes the full documentation and after reading it you should be > able to see: > > - that you can even start the server quickly from the world menu after > loading > - how easy it is to tinker and experiment with dynamic routes and Teapot in > an interactive way > - how easy it is to provide a REST interface by having methods annotated > with REST specific pragmas > - to even provide a versioned REST interface (also defined using pragmas) > > The document should easily explain all this, esepcially read "Defining a > REST based interface". > > This project is around since last october now (see > http://forum.world.st/ANN-Tealight-td4918431.html) > > > Lately I even added the possibility to remove one or all the dynamic routes > in a teapot inspector > (see attached screenshot).

[Ann] [Grafoscopio] New release with major improvements
by Offray Vladimir Luna CÃ¡rdenas Aug. 20, 2017

Aug. 20, 2017

Hi, In Grafoscopio, we follow a rolling release model, so we don't make a lot of noise about new versions, but this one has several features worthy to mention: a. Pharo 6 & 6.1 support, with out of the box 64 bits support on Mac and Gnu/Linux. b. Improved support for documentation: Now we have a GrafoscopioDocumentation object that defines documentation as a (Fossil) repository with a list of documents inside and is able to download and update them to their last version using the standard Fossil JSON API. c. Improved traceability: The usual document workflow in Grafoscopio is to create a notebook (i.e notebook.ston), export it as Markdown (notebook.markdown) and convert it to PDF (notebook.pdf) or HTMl (notebook.html). Now in the notebook.ston --> notebook.markdown --> notebook.pdf workflow, the exported/derived file contains the checksum of the last saved source file where it comes from. So, notebook.markdown contain the checksum of notebook.ston in the YAML metadata block [1][2], and notebook.pdf can show the checksum of the notebook.markdown, as exemplified in the User Manual [3]. [1] http://pandoc.org/MANUAL.html#extension-yaml_metadata_block [2] http://mutabit.com/repos.fossil/grafoscopio/artifact?name=99778d46ef034389&… [3] http://mutabit.com/repos.fossil/grafoscopio/doc/tip/Docs/En/Books/Manual/ma… d. Metadata config nodes: Now notebook internalizes the environment (as Smalltalkers and Lispers[4] like ;-)). "%medatata" nodes (see image below) allow a Grafoscopio notebook to define and control the command line options used by the operative system to export the notebook to other formats and enables the notebook to feedback such options with information provided/calculated by the notebook itself. This improves reproducibility greatly, because notebook now describes even the external operations to it, to create other derived files (Markdown, PDF, LaTeX and so on) and to interact with the operative system where it resides (currently this only works on Unix like operative systems like Mac and Gnu/Linux). Such configuration options are defined in plain Pharo, using just dictionaries and dynamic arrays, with some special keys. [4] https://youtu.be/JnczIyPXGfc?t=2548 e. Support for multiple tags in a node: Until now the only allowed tag was 'cÃ³digo' (code), but now tags can be almost arbitrary. This will open new ways to process and display the notebook document tree, once the proper GUI features and interactions are developed. f. Updated and corrected documentation: English User Manual has been improved to reflect new features and several typos and errors have been corrected. Last stable Grafoscopio version is available from the Pharo Catalog, and remember to run the update, frequently. Enjoy, Offray

Playground doesn't respect LF endings
by Peter Uhnak Aug. 19, 2017

Aug. 19, 2017

Hi, when I paste a text into the playground with line endings containing just LF (unix-style), then navigation to beginning/end of a line instead jumps to the beginning/end of the text. (I guess it is hardcoded to CR only). Right now I have to execute `Clipboard clipboardText withSqueakLineEndings asString` and then copy&paste the result. Peter

ZnConstants class>>#httpStatusCodes and cloudflare
by Holger Freyther Aug. 19, 2017

Aug. 19, 2017

Hi, I am currently using ZnClient to fetch data from a service behind "cloudflare" and sometimes the real/origin backend is unreachable/fails. Cloudflare has added additional[1] 5XX codes and ZnStatusLine>>#code: will signal an ZnUnknownHttpStatusCode because of that. I wonder how ZnClient should deal with these errors? IIRC the HTTP RFC specifies error classes and without knowing what "525" means one can know that the request was not successful and that the server is at "fault"? Should ZnStatusLine handle an unknown code gracefully? E.g. >>#reason: seems to do that already? have a nice weekend holger [1] https://en.wikipedia.org/wiki/List_of_HTTP_status_codes#Cloudflare

Pharo for Android
by Ricardo Pacheco Aug. 18, 2017

Aug. 18, 2017

I read some info dated 2014 that there where some efforts to make Pharo able to run on Android. Will new versions of Pharo (6.1 & 7) support Android. Does anybody use succesfully the most recent version of Pharo on a Android tablet? Thanks
