csv - Ruby Mechanize form input field text -


resolved - "abc = list.scan(/[([^)]+)]/).last.first" line correct included quotes, website search form did not accept. corrected abc = list.scan(/\"([^)]+)\"/).join.

thanks help.

i have automate search using list of 100 keywords in csv file.

with mechanize, can submit search using example (http://mechanize.rubyforge.org/guide_rdoc.html):

agent = mechanize.new page = agent.get('http://google.com/') google_form = page.form('f') google_form.q = 'ruby mechanize' page = agent.submit(google_form) pp page

however, when make loop through csv file, returns error (in example, first csv entry 'ruby mechanize':

#i have imported csv list, looping through array "raw_list"  raw_list.each |list| abc = list.scan(/\[([^\)]+)\]/).last.first  # tested "puts abc" returned "ruby mechanize", don't understand why rest of doesn't work   agent = mechanize.new page = agent.get('http://google.com/') google_form = page.form('f') google_form.q = abc  #even though abc = "ruby mechanize", error occurs.    page = agent.submit(google_form) pp page

it doesn't seem take variable "abc", works if manually type in 'ruby mechanize' though both same.

the error appears is:

c:filename: in `block (2 levels) in <top (required)>': undefined method `text' nil:nilclass (nomethoderror) c:/railsinstaller/ruby2.0.0/lib/ruby/gems/2.0.0/gems/mechanize-2.7.3/lib/mechanize.rb:442:in `get' c:/users/victor/rubymineprojects/untitled/scraper.rb:23:in `block in <top (required)>' c:/users/victor/rubymineprojects/untitled/scraper.rb:19:in `each' c:/users/victor/rubymineprojects/untitled/scraper.rb:19:in `<top (required)>' -e:1:in `load' -e:1:in `<main>'

any appreciated.

your error telling on line 19 in code causing issue line 442 in mechanize.

i tried sample out in irb , seems work fine:

2.2.2 :001 > require 'mechanize'  => true  2.2.2 :002 > agent = mechanize.new  => #<mechanize:... 2.2.2 :003 > page = agent.get('http://google.com/')  => #<mechanize::page   ... 2.2.2 :004 > google_form = page.form('f')  => #<mechanize::form  ... 2.2.2 :005 > google_form.q  => ""  2.2.2 :006 > abc = "ruby mechanize"  => "ruby mechanize"  2.2.2 :007 > google_form.q = abc  => "ruby mechanize"  2.2.2 :008 > page = agent.submit(google_form)  => #<mechanize::page  ...

scan return nil if nothing found error happening here:

abc = list.scan(/\[([^\)]+)\]/).last.first

http://ruby-doc.org/stdlib-2.2.0/libdoc/strscan/rdoc/stringscanner.html

you can replace with:

abc = list.scan(/\[([^\)]+)\]/).join

you'll string although may "".

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
