The ZnServerAdapter version should work fine Stephan

Re: [Pharo-users] Securely downloading Pharo

by Wilfred Hughes

Yep, a SHA sum is less useful if it's on the same site. Still, it would be really useful to check the file against accidental corruption. It would also be useful for comparing with the checksums used by packagers, e.g. https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=pharo#n27 . Users could see if their Pharo package was the same as the package on pharo.org. pharo.org very nearly works with HTTPS, it's just a few JS/CSS files that need to stop using absolute URLs (so e.g. "http://pharo.org/files/screenshots/pharo-is-yours.png" should be a protocol-relative URL "//pharo.org/files/screenshots/pharo-is-yours.png"). Is the site hosted somewhere that users can send patches to?

On a simpler front and not at as a real daba base, you may find Fuel to be incredibly efficient and reliable to persist a graph of object.

not sure, but WAKomAdaptor is I speak specific. You have to use Pharo variant, one subclass of WAAdaptor. Iâll try ZnZincServer adaptor. Cheers, CÃ©drik

Re: [Pharo-users] Documentation about Pharo Launcher?

Hi Damien, I will use a modified version of the Pharo 5 environment packaged for the current MOOC for a quick building and with more time I will create new ConfigurationOf for my projects and debug the current ones.

Re: [Pharo-users] Web browsing automation

by CÃ©drick BÃ©ler

Soup is quite easy to use (event if I would prefer an API that uses jQuery/CSS likes navigation selectors. Easier way is doing it interactively (in a debugger). Just to give an example so that you can start quickly, I just did something to scrap info from this web site db-ip. Info is in a table and I want its content: https://db-ip.com/8.8.8.8 So here is the sample code (soup has lots of examples too): self cache ''a dictionary to avoid scrapping again'' at: anIPString ifAbsent: [ soup := Soup fromUrl: 'https://db-ip.com/', anIPString. soupTable := soup findAllTags: 'table'. "ensure size =1" geolocDict := Dictionary new. soupTable first childTagsDo: [ :tag | geolocDict at: (tag children first next contents) put: (tag children second next contents) ]. self cache at: anIPString put: geolocDict].

Re: [Pharo-users] Web browsing automation

I think you have several possibilities : 1. testing user interactions by real click automations: donât know what is up todays but there were Albatross back in 2006 [1] or SeasideTesting [2]. Probably, there are other options. 2. Simulate client requests programmatically. You could do that in Zinc quite easily if you know the different url. Have a look at the book Â« Enterprise Pharo Â» [3] 3. BeautifulSoup is called Soup and is accessible through the catalog or SmalltalkHub [5]. Works well (note to pharoers: but I think that be nice to have an interface like scrappy instead). Now, as you say "Its a simple socket bridge with which pharo can communicate with python and say "hey python do this for me and return me the result Â». Iâd say the second option with Zinc seems to be the best approach, start with the chapter about client but youâll probably need the server chapter so as to get bidirectional connections. My guessâ¦ and interesting project btw :) HTH, CÃ©drik [1] http://scg.unibe.ch/archive/projects/Brue06a.pdf [2] http://www.shaffer-consulting.com/david/Seaside/TestingComponents/TestingCo… [3] http://files.pharo.org/books/enterprise-pharo/ [4] https://ci.inria.fr/pharo-contribution/job/EnterprisePharoBook/lastSuccessf… [5] http://www.smalltalkhub.com/#!/~PharoExtras/Soup
