is there way make serilog format structured data formatted output? i've been using structured data structures in serilog lately , though there advantage of being compact large data structures (5 properties or more) hard read in console/file without formatting later. hypothetically i'd enable on dev. https://github.com/serilog/serilog/wiki/structured-data from this: { "fruit": ["apple", "pear", "orange"] } to this: { "fruit": [ "apple", "pear", "orange" ] } edit: i'm using jsonconvert.serializeobject({...}, formatting.indented) i'd move away reasons proper coloring console package, faster serialization, deferred serialization etc. i seem recall had custom formatter @ work few years ago modify default json output serilog. not remember exact problem had. you take at, https://github.com/serilog/serilog/wiki/formatting-output , if haven't alre...

i have controller defined this: var servicesinstance = angular.module('myapp'); servicesinstance.controller('servicesviewcontroller', function() { console.log("servicesviewcontrollerconstructor."); this.initialize = function() { console.log("servicesviewcontroller initialize."); }; }); and instance of dynamically in code this: var instance = $injector.get('servicesviewcontroller'); note: please ignore hardcoded strings. post, hardcoded strings. however, in reality, controller name come configuration data (eg: json object). the instance variable null. $injector.has('servicesviewcontroller') returns false. why case? correct way controller instance? thank matt edit : throwing in more info kept out because trying keep question simple. using requirejs load javascript code creates controller. eg: define([], function(servicesviewcontrollerprovider) { 'use strict'; va...

i'm trying implement parser combinators educational purposes. parser defined std::function<t(input&)> . have come point able define simple expression grammar, using code: auto expression; // type not matter context auto factor = number | (token('(') >= expression >= token(')')) ; auto term = factor >= *( (token('*') | token('/')) >= factor ); expression = term >= *( (token('+') | token('-')) >= term ); as can seen, problem circular dependencies. can not figure out way resolve circular dependency grouped factor causes. operators constructing factor parser need expression parser constructed @ end. how resolve this?

so have these tables: products -------- product id | quantity and orderslines ----------- product id | amount --(multiple lines same id) i'm using select: select p.productid, p.quantity, sum(ol.amount) ordered atbl_sales_products p inner join atbl_sales_orderslines ol on ol.productid = p.productid group p.productid, p.quantity having p.quantity > sum(ol.amount) the select works if productid used in both tables. however, if productid not used in orderslines table or amount in table null - such rows not included. when want join across tables need include records 1 side of join or other, need use 1 of outer join s opposed inner join in sql. if want include record atbl_sales_products when there may no matching record in atbl_sales_orderlines same productid should use left join . as mentioned in comments can use operators use in where clause having clause.
