If the argument you pass to the function was a string, it would get the whole line from your file, which is "0 50 100" and put it in your string.</p> <p>You could trying to save it to a string and then splitting it to three parts and converting to ints using atoi or std::stoi in C++11 (check <a href="http://stackoverflow.com/questions/7663709/convert-string-to-int-c">Convert string to int C++</a>) - this way it would be easier to handle possible errors. </p> <p>But there's an easier way to do it - assuming your numbers are split by spaces and pretty much everything is correct with them, the ">>" operator breaks on spaces.

32,019,322 | 0 | HOWTO create GoogleCredential by using Service Account JSON <p>I am using the Java SDK for <code>Android Publisher v2</code> and <code>Oauth2 v2</code>. Once I created the service account I was provided with a JSON of <code>Google Play Android Developer</code> service account with client id, email, private key etc. I have tried to look around and figure out how to create a Credential so that I use the AndoirdPublisher service to fetch info on my Android App's users subscriptions, entitlements etc and store this info on our backend servers.</p> <p>I am getting hard time trying to figure out how to go about this. None of the documentations I have seen so far help in creating <code>GoogleCredential</code> using the downloaded JSON. </p> <p>For example there is this <a href="https://developers.google.com/identity/protocols/OAuth2ServiceAccount" rel="nofollow">documentation</a> but it mentions only about P12 file and not the JSON. I want to avoid P12 if possible since I have multiple clients & I would like to save this JSON in some sort of database & then use it to create credential for each client.</p> <p>Just to clarify I am trying to create the GoogleCredential object as described here,</p> <pre><code>import com.google.api.client.googleapis.auth.oauth2.GoogleCredential; import com.google.api.client.googleapis.javanet.GoogleNetHttpTransport; import com.google.api.client.http.HttpTransport; import com.google.api.client.json.JsonFactory; import com.google.api.client.json.jackson2.JacksonFactory; import com.google.api.services.sqladmin.SQLAdminScopes; // ... String emailAddress = "[email protected]"; JsonFactory JSON_FACTORY = JacksonFactory.getDefaultInstance(); HttpTransport httpTransport = GoogleNetHttpTransport.newTrustedTransport(); GoogleCredential credential = new GoogleCredential.Builder() .setTransport(httpTransport) .setJsonFactory(JSON_FACTORY) .setServiceAccountId(emailAddress) .setServiceAccountPrivateKeyFromP12File(new File("MyProject.p12")) .setServiceAccountScopes(Collections.singleton(SQLAdminScopes.SQLSERVICE_ADMIN)) .build(); </code></pre> <p>But instead of setting the Service Account using P12 File like so <code>setServiceAccountPrivateKeyFromP12File()</code>, I want to use the JSON that carries the same info & generated when I created the service account.</p> |

28,436,502 | 0 | Global data from eloquent in Laravel to be used for layout <p>I am using some variables in the layout which will load data from the eloquent.

29,349,710 | 0 | Can HTML <script defer> execute before <script async>? <p>I'm asking a question on a subject that has been well explored and there are many near-answers to what I am asking, but I haven't been able to find the exact answer to what is a simple question.</p> <p>I understand that defer scripts run in the order they appear on the page, but only after the DOM has been built, and I get that async scripts run as soon as is possible, and I know that neither one blocks the HTML parser.</p> <p>Here's the question: Is there a case in which a defer script can execute before all the async scripts have executed? Essentially, if the HTML parser has parsed the entire document and is ready to run the defer scripts BUT there are still some async scripts that have not loaded yet, will it wait for these async scripts to load (and execute), or will it run the defer scripts?</p> <p>Thanks!</p> |

2,852,961 | 0 | <p>It's identical to commenting out the block, except with one important difference: Nesting is not a problem. Consider this code:</p> <pre><code>foo(); bar(x, y); /* x must not be NULL */ baz(); </code></pre> <p>If I want to comment it out, I might try:</p> <pre><code>/* foo(); bar(x, y); /* x must not be NULL */ baz(); */ </code></pre> <p>Bzzt. Syntax error! Why? Because block comments do not nest, and so (as you can see from SO's syntax highlighting) the <code>*/</code> after the word "NULL" terminates the comment, making the <code>baz</code> call not commented out, and the <code>*/</code> after <code>baz</code> a syntax error. On the other hand:</p> <pre><code>#if 0 foo(); bar(x, y); /* x must not be NULL */ baz(); #endif </code></pre> <p>Works to comment out the entire thing.

35,264,429 | 0 | <p>I was given a task to invoke the batch job one by one.Each job depends on another. First job result needs to execute the consequent job program. I was searching how to pass the data after job execution. I found that this ExecutionContextPromotionListener comes in handy.</p> <p>1) I have added a bean for "ExecutionContextPromotionListener" like below</p> <pre><code>@Bean public ExecutionContextPromotionListener promotionListener() { ExecutionContextPromotionListener listener = new ExecutionContextPromotionListener(); listener.setKeys( new String[] { "entityRef" } ); return listener; } </code></pre> <p>2) Then I attached one of the listener to my Steps</p> <pre><code>Step step = builder.faultTolerant() .skipPolicy( policy ) .listener( writer ) .listener( promotionListener() ) .listener( skiplistener ) .stream( skiplistener ) .build(); </code></pre> <p>3) I have added stepExecution as a reference in my Writer step implementation and populated in the Beforestep </p> <pre><code>@BeforeStep public void saveStepExecution( StepExecution stepExecution ) { this.stepExecution = stepExecution; } </code></pre> <p>4) in the end of my writer step, i populated the values in the stepexecution as the keys like below</p> <pre><code>lStepContext.put( "entityRef", lMap ); </code></pre> <p>5) After the job execution, I retrieved the values from the <code>lExecution.getExecutionContext()</code> and populated as job response.</p> <p>6) from the job response object, I will get the values and populate the required values in the rest of the jobs.</p> <p>The above code is for promoting the data from the steps to ExecutionContext using ExecutionContextPromotionListener. It can done for in any steps.</p> |
4,033,061 | 0 | <p>The problem is that a <code>RewriteCond</code> only applies to the rule immediately following it, so your second <code>RewriteRule</code> is always run. One solution <a href="http://my.galagzee.com/2009/02/11/mod_rewrite-one-rewritecond-to-many-rewriterules/" rel="nofollow">is to negate the test you are making, then have the next command skip the two commands you want to run</a>.</p> <pre><code>RewriteCond %{DOCUMENT_ROOT}assets/img$1/.$2.$4/$3.$4 !-f RewriteRule . - [S=2] RewriteRule ^assets/img(.*)/([a-zA-Z0-9-_\.]*)\.([^/]+)\.([a-z]{2,4})$ assets/img$1/.$2.$4/$3.$4 [NC,QSA] RewriteRule ^assets/img(.*)/([a-zA-Z0-9-_\.]*)\.([^/]+)\.([a-z]{2,4})$ assets/img/image.php?path=$1&file=$2.$4&key=$3 [NC,L,QSA] </code></pre> |
26,117,059 | 0 | <p>Here's a unicode aware implementation as a category on <code>NSString</code>:</p> <pre><code>@interface NSString (NRStringFormatting) - (NSString *)stringByFormattingAsCreditCardNumber; @end @implementation NSString (NRStringFormatting) - (NSString *)stringByFormattingAsCreditCardNumber { NSMutableString *result = [NSMutableString string]; __block NSInteger count = -1; [self enumerateSubstringsInRange:(NSRange){0, [self length]} options:NSStringEnumerationByComposedCharacterSequences usingBlock:^(NSString *substring, NSRange substringRange, NSRange enclosingRange, BOOL *stop) { if ([substring rangeOfCharacterFromSet:[NSCharacterSet whitespaceCharacterSet]].location != NSNotFound) return; count += 1; if (count == 4) { [result appendString:@" "]; count = 0; } [result appendString:substring]; }]; return result; } @end </code></pre> <p>Try it with this test string:</p> <pre><code>NSString *string = @"ab 132487 387 e e e "; NSLog(@"%@", [string stringByFormattingAsCreditCardNumber]); </code></pre> <p>The method works with non-BMP characters (i.e. emoji) and handles existing white space.</p> |
21,578,803 | 0 | <p>I have now managed to get it working. I have had to set the prefix for the plugins models to "media_" and then have the class names as "Media.Item" and call "$this->Item->find()" to get the containable behaviour to work.</p> |
