Scrappy Comments: Looks interesting, but the docs are a bit scattered and felt confusing, and the development seems to have stagnated.

scrappy is too much pee as I say in Re: Scrappy user_agent error

... spidering ... scraping ...

You're confusing yourself there a little, spidering (anything goes) is a completely different ballgame than scraping (this one particular site)

WWW::Mechanize makes LWP bearable for scraping

WWW::Mechanize::Firefox adds JS support

that's it for scraping, the bare essentials and the state of the art, all the others add a little sugar and some baggage

WWW::Scripter adds "JS support" WWW::Scripter::Plugin::JavaScript/WWW::Scripter::Plugin::Ajax... very impressive/neat, but it ain't no WWW::Mechanize::Firefox

Web::Scraper adds a little sugar, like

Web::Magic adds maximum magic with maximum dependencies

Web::Query adds maximum sugar with minimal dependencies, like jQuery, but has odd bits

-Mojo is slick but Mojo::DOM is still barren (pita)

XML::LibXML -- has work to do, it can load html/xml documents from urls but the headers/post/... HTTP stuff isn't there yet


Mozilla::Mechanize -- good luck building that :) it ain't easy, no it aint easy

Gtk3::WebKit -- its a browser , you might scrape with it somehow (probably not)

[ambrus]: Now it has five people instead of three, some sort of call number ticket system where people wait a lot for their food to get ready (it's the same kinds of grilled meat and fish on the same equipment, it won't actually fry slower),
[ambrus]: it's slow as hell, and the food costs significantly more.
[ambrus]: We no longer eat there.
LanX Everybody quotes it, some people read it, and a few people go by it
[ambrus]: LanX: why would I read it? isn't it a book for managers? I don't want to be a manager.
[ambrus]: I don't quote it either.
[erix]: it's really a software book, albeit about experiences from the 60s-80s. People haven't changed all that much though.
[erix]: a software project book, is probably more exact
[ambrus]: Yes, but I'm not managing software teams either.
[ambrus]: I'm not only not a restaurant manager, but also not a software manager.
