Re: [Pharo-users] Spec with dynamic tabs

by Peter UhnÃ¡k

Can you add an issue for Pharo 5 so it doesn't get lost? Currently a lot of effort is focused on Pharo 4 release (this week-ish), so nobody might have time to look at this now.

Re: [Pharo-users] ZnClient: getting more that 19 tweet for data scrapping

by Sven Van Caekenberghe

What Paul showed is basically just a hack. What you probably what is full API access to Twitter, that gives you the real thing, but it is more work and you have to understand all the technical details (unless somebody already did it for you, I don't know - I know that Zinc-SSO can connect to Twitter). https://dev.twitter.com/overview/api > On 07 Apr 2015, at 20:23, Offray Vladimir Luna CÃ¡rdenas <offray(a)riseup.net> wrote: > > Hi, > > Recently Paul DeBruicker taught me how to refine my code for getting tweets properly.

ZnClient: getting more that 19 tweet for data scrapping

by Offray Vladimir Luna CÃ¡rdenas

Hi, Recently Paul DeBruicker taught me how to refine my code for getting tweets properly. Consider this: =[1]==================================== | source anUrl tweet | anUrl := 'https://twitter.com/offrayLC'. source := Soup fromString: (ZnEasy get: anUrl ) contents asString. tweets := (source findAllTagsByClass: 'ProfileTweet-text') collect:[:ea | ea text]. ======================================== Is working fine, but I would like to get more that 19 tweets, that is what you get by default. There is any way to tell ZnEasy and friends to get more tweets, something similar to what you do when you scroll down into a twitter page? And by the way, I would like to make more sense of the Soup I got in the last line. ea text gives me the tweet contents, but how can I interpret the metadata in the soup? (is a retweet, date of publishing and so on). I could make this for most part of the twitter profile page, but the tweet is kind of elusive, for example how to know that "text" is the proper message for getting the tweet content? Any pointer to how to make sense of it by myself is greatly appreciated. Cheers, Offray

Re: [Pharo-users] Showcase of initial support for word clouds and data scrapping (and the usual newbie questions)

by Offray Vladimir Luna CÃ¡rdenas

Thanks Nicolai, you were right. The problem was not on the image format, but on the parsing of the date. It was just that my non working test were located at places where, coincidentally, the images were on jpg format and I was misreading the signals :-). Now both, date scrapping/formating and images in jpeg and png, are working properly. Last version of Dataviz[1] reflect that changes.
