ruby - Why don't my regex scans work? -


i have script scans text file , puts csv file. grabs debtor information, puts creditor information following it.

the problem is, gets each debtor puts same creditor information each debtor, it's not getting new information below debtor:

fastercsv.open('data.csv', 'a') |csv|    debtor_info = results.scan(/^(\d{2}\-\d{5})(\s+)(.*)(\s+)(total:)(\s+)(\$(\d+\,?   \.?)+)/)     debtor_info.each |line|    case_number = line.at(0)    debtor = line.at(2).strip    total_amount = line.at(6)    csv << [case_number, debtor, total_amount]      creditor_info = results.scan(/((\d{1,2})\/(\d{1,2})\/(\d{1,4}))\s+(\$(\d+\,?\.?)+)\s+(\d{1,5}bk)\s+(.*)/)   creditor_info.each |info|        date = info.at(0)        amount = info.at(4)        fund_number = info.at(6)        creditor = info.at(7)        empty = " "        csv << [empty, date, amount, fund_number, creditor]       end  end end

this sample input:

with given structure, need scan either creditor or debtor line single list, work through it, setting "current debtor" whenever encounter one.

assuming results slurp of input file (you don't say, looks likely):

combined_info = results.scan(/^(\d{2}\-\d{5})(\s+)(.*)(\s+)(total:)(\s+)(\$(\d+\,?\d+\.?)+)|((\d{1,2})\/(\d{1,2})\/(\d{1,4}))\s+(\$(\d+\,?\.?)+)\s+(\d{1,5}bk)\s+(.*)/) case_number = "unknown" debtor = "unknown" total_amount = "unknown"  combined_info.each |line|   # if it's debtor, set variables, no output   if line.at(0)     case_number = line.at(0)     debtor = line.at(2).strip     total_amount = line.at(6)     next   end    # creditor, collect data , output, note our capture indices have moved . . .   date = line.at(8)   amount = line.at(12)   fund_number = line.at(14)   creditor = line.at(15)   empty = " "   csv << [case_number, debtor, total_amount, empty, date, amount, fund_number, creditor] end

your regexes little work, (such removing non-necessary captures), should started.

there may other approaches fit data input in cleaner way - instance line-by-line identification during input rather use .scan - answer intended build on existing approach.

keyboard - C++ GetAsyncKeyState alternative -

i using windows.h library's getasynckeystate function define key pushed on keyboard . here program returns int value of pushed key example. #include <iostream> #include <windows.h> using namespace std; int main (){ char i; for(i=8;i<190;i++){ if(getasynckeystate(i)== -32767){ cout<<int (i)<<endl; } } return 0; } but trying make opengl simple game , function appeared slow . there function not need cycle 180 times , if statement . thanks you're trying make opengl game, you're going use glfw. if that's case can away using glfwgetkey() such: if (glfwgetkey(glfw_key_up) == glfw_press) {...} if (glfwgetkey(glfw_key_down) == glfw_press) {...} that method nicely explained in tutorial 6 opengl-tutorial.org . should start first tutorial of beginners tutorials , later intermediate tutorials . if you're going make win32 window can listen wm_keydown or wm_keyup messages , virtua...
