break

问题 I have a csv-file, now i need to bring it in another form. I want to have a line break \r\n after a specific pattern. All patterns look like this: true or false; int number between 0 and 100; decimal number with two or three digits after the point; true or false; For example: false;2;23.987;false; true;0;8.37;false; false;8;166.987;false; and after the last semicolon, i want to have a line break. I am using notepad++. Thanks for your help 回答1: You may use \b(?:true|false);\d+;\d+\.\d+;(?:true

问题 I need to break a loop which has a condition inside it, on any circumstance which the condition meets the exception like this: for($l=0; $l<$subject_count; $l++){ for($a=0; $a<$term_relatives_id_array_count; $a++){ if($subject_array[$l]['id'] == $term_relatives_id_array[$a]['subject_id']){ $subject_echo = true; break; } echo 'a'; } if(!$subject_echo){ echo '<li class="selectable_item" id="'.$subject_array[$l['id'].'">'.$subject_array[$l]['name_fa']; echo '</li>'; } } I used echo 'a'; to see

问题 I have a RegExp, doing a string replace, with global set. I only need one replace, but I'm using global because there's a second set of pattern matching (a mathematical equation that determines acceptable indices for the start of the replace) that I can't readily express as part of a regex. var myString = //function-created string myString = myString.replace(myRegex, function(){ if (/* this index is okay */){ //!! want to STOP searching now !!// return //my return string } else { return

问题 Suppose I have got a shorthand if-else statement inside a loop as in this case : for(...) { a = b == c ? b : c; // More unnecessary code if the result was true. } And I would like to break the loop by the result of the condition: for(...) { a = b == c ? b break : c; // Now the unnecessary code is not executed. } I realize I could just type it in a full way as in this example: for(...) { if( b == c ) { a = b; break; } else { a = c; } // Now the unnecessary code is not executed. } But it is too

问题 I have a program that does some data analysis and is a few hundred lines long. Very early on in the program, I want to do some quality control and if there is not enough data, I want the program to terminate and return to the R console. Otherwise, I want the rest of the code to execute. I've tried break , browser , and quit and none of them stop the execution of the rest of the program (and quit stops the execution as well as completely quitting R, which is not something I want to happen). My
