GHCi uses a configuration file in ~/.ghci. A configuration file consists of a sequence of commands which GHCi will execute on startup. $ echo ":set prompt \"foo> \"" > ~/.ghci $ ghci GHCi, version 8.0.1: http://www.haskell.org/ghc/ :? for help Loaded GHCi configuration...

(u)gettext_noop allows you to mark a string as translatable without actually translating it. A typical use case is when you want to log a message for developers (in English) but also want to display it to the client (in the requested language).

All functions to interact with coroutines are avaliable in the coroutine table. A new coroutine is created by using the coroutine.create function with a single argument: a function with the code to be executed: thread1 = coroutine.create(function() print("honk") end)...

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 ...

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...

Example uses basic HTTP syntax. Any <#> in the example should be removed when copying it. You can use the _cat APIs to get a human readable, tabular output for various reasons. GET /_cat/health <1> _cat/health has existed since Elasticsearch 1.x, but here is an example of its output...

Example uses basic HTTP syntax. Any <#> in the example should be removed when copying it. Like most _cat APIs in Elasticsearch, the API selectively responds with a default set of fields. However, other fields exist from the API if you want them: GET /_cat/health?help <1> ?help cau...

Example uses basic HTTP syntax. Any <#> in the example should be removed when copying it. The _cat APIs are often convenient for humans to get at-a-glance details about the cluster. But you frequently want consistently parseable output to use with software. In general, the JSON APIs are meant...
