Re: [Pharo-users] Web browsing automation

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]. Cheers, CÃ©drik

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

Re: [Pharo-users] Can you help me find this info?

Performance wise Pharo is doing very well on that front because its one of the very few dynamic languages to come with a JIT VM. Generally speaking because you are talking about games, it will depend on the game. Both Android and iOS they rely heavily on C libraries, libraries that Pharo can use. So performance is not our problem nor we need hardware VM support because graphics are already heavily hardware accelerated. The problem for pharo is support of those platforms, like multi touch, a more multi touch friendly GUI etc. Generally speaking expect to get your hands dirty on making C libraries working with Pharo on those platforms a lot more than worrying about VM speed. Even for heavy 3d games would could use something like Unreal or Unity together with Pharo. On iOS it may be an issue because Apple allows for a single executable. So the problem here is not speed, its the diffirent way of doing things on those platforms that would require a lot of boilercode to make things work smoothly. This is why game devs prefer using something like Unity and Unreal that are well tested and offer all those luxuries outside the box without you having to worry about that.

My project is basically a unification of python and pharo by allowing pharo to use python libraries. That means that one would have to have knowledge of python and the python library used. 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". This problem seems to me to be more suitable for BeautifulSoup https://www.crummy.com/software/BeautifulSoup/bs4/doc/ which has been ported to Pharo but it seems to no longer be in SmalltalkHub I can only find it here http://www.squeaksource.com/@-SEx5I4XPThwdDpe/-yS8D9eS On Wed, May 4, 2016 at 2:12 PM Peter UhnÃ¡k <i.uhnak(a)gmail.com> wrote: > As far as I know: > > Pharo has event recorder that helps automate within imageâ¦ however the > bigger problem here is interaction with the environment, which is a big > problem cross-platform. > > This is all assuming that you _must_ click on it and you can't just > retrieve-html/parse/extract/download/repeat which is doable in Pharo with > Zinc and some non-validating parser. > > If you don't find anything, you can take a look at PyAutoGUI > https://pyautogui.readthedocs.io/en/latest/ (or xdotool on linux). > > I believe Kilon worked on some python bindings from Pharo?

Thanks. I will be happy with either way - clicks automation or "retrieve-html/parse/extract/download/repeat"; I just want to find the most convenient way (e.g. quick and simple). I do not have any experience with html parsing; maybe you could point at some relevant examples / tutorial?

As far as I know: Pharo has event recorder that helps automate within imageâ¦ however the bigger problem here is interaction with the environment, which is a big problem cross-platform. This is all assuming that you _must_ click on it and you can't just retrieve-html/parse/extract/download/repeat which is doable in Pharo with Zinc and some non-validating parser. If you don't find anything, you can take a look at PyAutoGUI https://pyautogui.readthedocs.io/en/latest/ (or xdotool on linux). I believe Kilon worked on some python bindings from Pharo? It would be interesting to ask him what was that exactlyâ¦ maybe it could be connected to this lib.

Web browsing automation

by Grigory Hatsevich

Suppose I have a web page with 50 small photos; when I click on a photo, appears a window where I can further click on a link to open a full profile of the person on a photo. I need to open a full profile for every person in that page, each in a separate browser tab. How can I automate this clicking, so that I would not need to click at every link manually? Does Pharo have tools for such tasks?
