Python 2 includes a cmp function which allows you to determine if one object is less than, equal to, or greater than another object. This function can be used to pick a choice out of a list based on one of those three options. Suppose you need to print 'greater than' if x > y, 'less than' if x &...

Elasticsearch uses a YAML (Yet Another Markup Language) configuration file that can be found inside the default Elasticsearch directory (RPM and DEB installs change this location amongst other things). You can set basic settings in config/elasticsearch.yml: # Change the cluster name. All nodes in ...

If you need to apply a setting dynamically after the cluster has already started, and it can actually be set dynamically, then you can set it using _cluster/settings API. Persistent settings are one of the two type of cluster-wide settings that can be applied. A persistent setting will survive a fu...

If you need to apply a setting dynamically after the cluster has already started, and it can actually be set dynamically, then you can set it using _cluster/settings API. Transient settings are one of the two type of cluster-wide settings that can be applied. A transient setting will not survive a ...

Index settings are those settings that apply to a single index. Such settings will start with index.. The exception to that rule is number_of_shards and number_of_replicas, which also exist in the form of index.number_of_shards and index.number_of_replicas. As the name suggests, index-level setting...

You can apply the same change shown in the Index Settings example to all existing indices with one request, or even a subset of them: PUT /*/_settings { "index": { "indexing.slowlog.threshold.index.warn": "1s", "search.slowlog.threshold": { ...

Example uses basic HTTP, which translate easily to cURL and other HTTP applications. They also match the Sense syntax, which will be renamed to Console in Kibana 5.0. Note: The example inserts <#> to help draw attention to parts. Those should be removed if you copy it! PUT /my_index <1&gt...

ANTLR is capable of generating parsers for a number of programming languages: C# Target Python Target JavaScript Target Java Target By default ANTLR will generate a parser from commandline in the Java programming language : Java -jar antlr-4.5.3-complete.jar yourGrammar.g4 //Will output a ...

Often you design coroutines to naturally end when certain goals are met. IEnumerator TickFiveSeconds() { var wait = new WaitForSeconds(1f); int counter = 1; while(counter < 5) { Debug.Log("Tick"); counter++; yield return wait; } ...

import std.stdio; struct A { int b; void c(); string d; }; void main() { // The following foreach is unrolled in compile time foreach(name; __traits(allMembers, A)) { pragma(msg, name); } } The allMembers traits returns a tuple of string containing t...

Let's say, we have a simple LoginForm class with rules() method (used in login page as framework template): class LoginForm { public $email; public $rememberMe; public $password; /* rules() method returns an array with what each field has as a requirement. * Login form u...
