DESCRIPTION¶ Property lists are ordinary lists containing entries in the form of either tuples, whose first elements are keys used for lookup and insertion, or atoms, which work as shorthand for tuples {Atom, true}. (Other terms are allowed in the lists, but are ignored by this module.) proplists模块适用数据量较少的场景,处理配置文件和函数选项时常用.proplists对内部数据结构是Key-Value键值对形式,第一个元素做key用来查询和删除,如果一个key有多个值就会使用第一次出现的值,其它被忽略.proplists对于Key和Value的约束极其宽松,可以是任意term().甚至可以把{Atom,true}缩写成为A Erlang proplists support in Access Showing 1-3 of 3 messages. Erlang proplists support in Access: OvermindDL1: 10/12/17 7:36 AM: I took a quick look in Access and I'm json arrays are represented with erlang lists of json values as described in this section. objects. json objects are represented by erlang proplists. json maps may also be encoded to json and optionally decoded to maps (via the return_maps option) To work with proplists, you can use the proplists module. It contains functions such as proplists:delete/2, proplists:get_value/2, proplists:get_all_values/2, proplists:lookup/2 and proplists:lookup_all/2.

Erlang records of a given type have a fixed number of fields with fixed field This is a quick introduction to the Elixir syntax for Erlang developers and Proplist = [{another_key, 20}, {key, 10}]. proplists:get_value(another_key, Proplist ).
Erlang is one of the less popular and known languages among the developer community which could deliver high availability using internal constructs of the programming language and the virtual machine running on beams ( similar to bytecode in java ).

Helper module for working with common Erlang representations of JSON: eep 18, map, mochijson-style, and proplists. This work is inspired by ej, but handles all common JSON representations: eep-18, map, mochijson-style and proplists, the types returned by jsone, jiffy, and mochijson, for example. erlang_mod(proplists) architectures: aarch64, x86_64.

I guess the only way to understand how this works is for me to understand more about Erlang, if you have any pointers/tips for learning Erlang I would be very grateful (I come from a Perl, C, Java background) Many thanks Jeremy _____ From: david martin To: user@couchdb.apache.org Sent: Monday, 28 May 2012, 9:40 Subject: Re: Erlang reduce functions We have moved our bug tracking to GitHub Issues.Please create new issues or comment there instead.

Description. Property lists are ordinary lists containing entries in the form of either tuples, whose first elements are keys used for lookup and insertion, or atoms, which work as shorthand for tuples {Atom, true}. Suppose the list is passed as argument to a function, to extract the values should I use: proplists:get_value (a, L). proplists:get_value (b, L). proplists:get_valus (d, L). Or should I simply use pattern matching as: [ {a, 1}.
