truncate

问题 I have a Yahoo Pipe where I bring in a number of feeds via an OPML file. Rather than using truncate to limit the resulting number of items that get exported, I want to limit the number of items on a per feed basis. So if I have 60 feeds I want the latest 20 items from each one, not the latest 20 from the combined feeds. 回答1: You can do this by creating 2 pipes: A pipe that fetches a feed (one of the 60), and truncates after 20 items Another that loops over feed URLs, and for each URL calls

问题 Is there a way that I can force setw to truncate? Say that I want to get the output: blah blah blee le bu blah blah blee Is there a way to make this work: string foo{"bu blah blah blee le"}; cout << setw(foo.size() - 3) << foo.data() + 3 << setw(foo.size() - 3) << foo << endl; 回答1: No, not really. You can switch to unformatted output for this example, though: assert(foo.size() > 3); cout.write(&foo[3], foo.size() - 3); cout.write(&foo[0], foo.size() - 3); 回答2: Not directly. In the printf

问题 Good afternoon! I am a Powershell novice trying to understand how data output works. I am trying to find the differences between two users in Active Directory. I found a solution that worked (Compare-Object on two AD user accounts), but the data some of in the relevant fields was truncated with an ... which didn't help. I found a solution which seems very elegant at the bottom of the page here: http://poshoholic.com/2010/11/11/powershell-quick-tip-creating-wide-tables-with-powershell/ I

问题 There are plenty of threads about people thinking they have lost digits when reading in a csv file, and it's just a digits setting that isn't displaying all of them. I on the other hand want to round or truncate my incoming data to two decimal places. I am having an issue in Rmarkdown where I can't limit the decimal places after highlighting fields. This has lead to me attempting to round before the highlighting, but that leads to undesirable results if I go lower than 4 places since I am

问题 I am calculating 16 bit checksum on my data which i need to send to server where it has to recalculate and match with the provided checksum. Checksum value that i am getting is in int but i have only 2 bytes for sending the value.So i am casting int to short while calling shortToBytes method. This works fine till checksum value is less than 32767 thereafter i am getting negative values. Thing is java does not have unsigned primitives, so i am not able to send values greater than max value of

问题 I have a project where I need to layout a newspaper like layout with columns but the columns must be a specific height (can at least extend a very little if need be) but holds dynamic content. I need to cut the text, after a sentence ends (a period) even if that means it extends slightly past the limit. I have tried to find back-end solutions to this (as well as attempted my own), css solutions and tricks (overflow:hidden looked horrible) and other tricks here and there but cannot seem to

问题 I am working on an ASP.NET C# accounting app and I am in the transition from using floats/doubles to using decimals to represent money. Now I want to control when and where rounding takes place. The way I understand it, SQL server rounds decimal data types differently than C# does. Is there some way to get SQL server (2008) to warn or fail if decimal values (or any kind of data) are getting truncated or rounded? Thanks, 回答1: Look at SET NUMERIC_ROUNDABORT and the table with SET ARITHABORT

问题 I have been working on a CMS for months now, I have faced various challenges with laravel truncating certain special characters. I had to change the editor in the CMS from bootstrap wysiwyg to ckeditor things got quite better as there are some advance escaping options that come with it. For example I was able to prevent '"' from becoming '" which was causing the entire string (paragraph) to truncate where ever it finds such encoding. However this is a CMS where the user has a good reason to

问题 Is there an official PHP function to do this? What is this action called? 回答1: No, there is no built-in function, but you can of course build your own: function str_truncate($str, $length) { if(strlen($str) <= $length) return $str; return substr($str, 0, $length - 3) . '...'; } 回答2: function truncateWords($input, $numwords, $padding="") { $output = strtok($input, " \n"); while(--$numwords > 0) $output .= " " . strtok(" \n"); if($output != $input) $output .= $padding; return $output; }
