I needed to do some screen scrapping using Ruby, so after a few google searches I came across this
post which looked very promising, after a quick scan through the comments
scRUBYt looked even better.
stumbling block #1: well it did take me a bit to get it installed, turns out it is currently (0.3.4) hard-wired to use RubyInline 3.6.3, but I had RubyInLine 3.7.0 installed, this
post gives the details to work around this issue, otherwise you will get an error something like
Gem::Exception: can't activate RubyInline (= 3.6.3), already activated RubyInline-3.7.0].
stumbling block #2: trying the simple example for scrapping google
here I got the following error -
can't convert Hash into String. So I tried commenting out some of the code, just limiting it to hit the submit button, the result - no error but no output either? after looking around on the
scRUBYt forums turns out scRUBYt logging is not on by default, so turn it on...
Scrubyt.logger = Scrubyt::Logger.new and run the code again
[ERROR] No extractor defined, exiting... ok, so un-comment the code and run it again now that I have the logging on, same error, I am obviously doing something wrong? try a couple other code samples, more fun error messages -
The error occurred while evaluating nil.example_type.
Well it turns out I was jumping ahead because I was calling this code from inside a
Rake task. After moving the code into a regular ruby file and calling it using ruby instead of rake everything works just great! I did not look into why this code is failing from inside the rake task but I am guessing there is some conflict with the libraries? an exercise for another day...
Next to the door is an electric burner not as nice as cooking with gas but good enough to cook in, if you like
