I need to format decimal numbers with patterns in J2ME just like java DecimalFormat . I see an option to port Format / NumberFormat / DecimalFormat . Can you suggest ready to use implementation or library? Thanks! So, I've manage to port desktop java implementation: bbnumberformat : String[] patterns = new String[] { "#,#00.00#", "0.0;(0.0)", "0.###E0" }; DecimalFormat format = (DecimalFormat) DecimalFormat .getNumberInstance(); double value = -12.321; for (int i = 0; i < patterns.length; i++) { String pattern = patterns[i]; format.applyPattern(pattern); String text = "Pattern: " + pattern + "

My project has a requirement to show amount field in currency format. I can achieve this onblur event, but let me know if this can be achieved using filters or some other AngularJS technique.

Named parameter string formatting in C++

问题 I'm wondering if there is a library like Boost Format, but which supports named parameters rather than positional ones. This is a common idiom in e.g. Python, where you have a context to format strings with that may or may not use all available arguments, e.g. mouse_state = {} mouse_state['button'] = 0 mouse_state['x'] = 50 mouse_state['y'] = 30 #... "You clicked %(button)s at %(x)d,%(y)d." % mouse_state "Targeting %(x)d, %(y)d." % mouse_state Are there any libraries that offer the

Python-equivalent string formatting with dictionary in Perl with hashes

由 懵懂的女人 提交于 2019-12-04 10:05:57
I love the way Python can format a string with a dictionary: print "%(key1)s and %(key2)s" % aDictObj I want to achieve the same thing in Perl with hashes. Is there any snippet or small library to do so? EDIT: Thanks for trying this answer. As for me, I came out with a short piece of code: sub dict_replace { my ($tempStr, $tempHash) = @_; my $key; foreach $key (sort keys %$tempHash) { my $tmpTmp = $tempHash->{$key}; $tempStr =~ s/%\($key\)s/$tmpTmp/g; } return $tempStr; } It just works. This is not as feature-complete as Python string-formatting with a dictionary but I'd like to improve on

ASP.NET WebAPI: How to control string content returned to client?

由 纵然是瞬间 提交于 2019-12-04 09:05:01
问题 In WebAPI, say I return a string wrapped in an HTTP response: return Request.CreateResponse(HttpStatusCode.BadRequest, "Line1 \r\n Line2"); When invoking this action from jQuery, the response text is treated before it is returned. So in the xhr, I get something like this: function success(xhr) { alert(xhr.responseText); // alerts ""Line1 \\r\\n Line2"" } In other words, the string gets wrapped in double quotes, and special characters get escaped so that they appear in the output (actual alert

问题 List<string> test = new List<string>(); test.Add("test's"); test.Add("test"); test.Add("test's more"); string s = string.Format("'{0}'", string.Join("','", test)); now the s is 'test's','test','test's more' but I need to replace the inner quotes with 2 single quotes like this: 'test''s','test','test''s more' update: I got it to work as below, but I would prefer a cleaner way if possible. string s = string.Format("`{0}`", string.Join("`,`", test)).Replace("'", "''").Replace("`", "'"); 回答1:

C# - Insert a variable number of spaces into a string? (Formatting an output file)

问题 Alrighty, I'm taking data from a list that I populate a DataGridView with and am exporting it to a text file. I've already done the function to export it to a CSV, and would like to do a plain text version as well. Because the Titles and other elements are variable in length, when the file is saved and then opened in Notepad it looks like a mess because nothing lines up. I'd like to have the output look like this: Sample Title One Element One Whatever Else Sample Title 2 Element 2 Whatever
