string-interpolation

I have a python logger set up, using python's logging module. I want to store the string I'm using with the logging Formatter object in a configuration file using the ConfigParser module. The format string is stored in a dictionary of settings in a separate file that handles the reading and writing of the config file. The problem I have is that python still tries to format the file and falls over when it reads all the logging-module-specific formatting flags. { "log_level":logging.debug, "log_name":"C:\\Temp\\logfile.log", "format_string": "%(asctime)s %(levelname)s: %(module)s, line %(lineno

I have used with below interpolation in html page. <div>{{config.CompanyAddress.replace('\n','<br />')}}</div> and also used <div>{{config.CompanyAddress.toString().replace('\n','<br />')}}</div> But both are showing text as below {{config.CompanyAddress.replace('\n','<br />')}} {{config.CompanyAddress.toString().replace('\n','<br />')}} Siddharth Sharma You can use a pipe for the same: import { Pipe, PipeTransform } from '@angular/core'; @Pipe({name: 'replaceLineBreaks'}) export class ReplaceLineBreaks implements PipeTransform { transform(value: string): string { return value.replace(/\n/g, '

Why does string interpolation prefer overload of method with string instead of IFormattable ? Imagine following: static class Log { static void Debug(string message); static void Debug(IFormattable message); static bool IsDebugEnabled { get; } } I have objects with very expensive ToString() . Previously, I did following: if (Log.IsDebugEnabled) Log.Debug(string.Format("Message {0}", expensiveObject)); Now, I wanted to have the IsDebugEnabled logic inside Debug(IFormattable) , and call ToString() on objects in message only when necessary. Log.Debug($"Message {expensiveObject}"); This, however,

When doing format string interpolation in Sweden I get a comma instead of a dot when creating strings with decimal numbers: scala> val a = 5.010 a: Double = 5.01 scala> val a = 5.0101 a: Double = 5.0101 scala> f"$a%.2f" res0: String = 5,01 My question is, how do I set the format so that I get the result 5.01 ? I would like to be able to set the locale only for that String, i.e. so that I don't change the locale for the whole environment. Cheers, Johan VonC Using the same Java library number formatting support accessible from StringOps enriched String class , you could specify another locale

I am trying to write a method in Ruby that uses a here-document of HTML code with input variables and fills them in accordingly. My method is: calcForm(left, op, right, result) The html tags I am using are <input type="text" name="left" value="?????"> <select name="op"> <option value="add" ?????>+</option> <option value="mul" ?????>*</option> </select> <input type="text" name="right" value="?????"> = ????? Everywhere there are question marks my method has to fill in with variables left, op, right, and result. For example, calcForm(6, "mul", 7, 42) should return the string: <input type="text"
