drools dsl adding expression to last pattern with '-' not working

由 纵饮孤独 提交于 2020-08-03 07:29:20
问题 I have been working with drools rules for a while and just recently started on a dsl to make the rule authoring easier for end users. While I have been able to get a simple dsl defined and correctly compiling into drl as expected, i cannot get the dsl feature of 'adding constraints to previous expression' to work. I am even trying the simplest of examples from the drools dsl guide and this will not compile the Conditions i have defined beginning with '-' into the previous expression. I keep

Fluent interface with Python

由 南笙酒味 提交于 2020-06-25 05:36:49
问题 I have a Python function "send_message" which takes three arguments: send_message("i like windmills", to="INBOX", from="OUTBOX") I am thinking about putting a fluent interface on top of it. Ideally I'd like to write the following: send_message("i like windmills").to("INBOX").from("OUTBOX") or send_message("i like windmills").from("OUTBOX").to("INBOX") Update: The to() information is mandatory but the from() is not (as with real letters). So this one would also be a valid call: send_message("i

How to perform Sub Aggregation using NEST?

DSL概述

DSL探讨的问题 DSL本身只是一层为了表达的能力而做的浅浅封装，在你考虑DSL的时候你应该将绝大部分的精力花在构建语义模型上，但反过来说DSL的设计从某种程度上来说帮你理清了语义模型的需求，这让我们看起来开始像一条产品狗了（笑），接下来我们大致过一下DSL设计和实现主要考虑的问题吧。 首要的就是如何设计DSL表达形式和你的语义模型，这是领域相关的技术 如何解析DSL文件并根据情况生成IR（中间数据） 如何在解析过程中或者在解析之后通过DSL 来构建语义模型 有时候仅仅得到语义模型是不够的，我们需要考察一些代码生成之类的输出相关的问题。 接下来我们将分别详细介绍这些主题。 解析DSL 这里的解析DSL显然指的是外部DSL，那么我们接下来讨论的你可能在编译原理前端都已经听到过了，但我还是需要在这里再简要地讲述一遍，请原谅我的啰嗦。 解析的过程主要可以分为词法解析、语法解析，视你的DSL的复杂程度你可能还需要在中间生成符号表，使用语境变量和维护作用域上下文。词法解析过程将DSL文本解析成一个Token Stream，token包含词的原始内容和位置，同时这个过程将会丢弃一些无用的字符比如空格符等。语法解析从Token Stream中生成语法解析树，在生成的过程中你可以采取一系列的动作来组装你的语义模型，这一点我们到下一节再讲。 接下来让我们考虑一下最简单的情形，比如读入一个CSV文件

Using a DSL to generate C# Code

由 你。 提交于 2020-02-19 04:54:30
问题 Currently the project I'm working with does not have completely fixed models (due to an external influence) and hence I'd like some flexibility in writing them. Currently they are replicated across three different layers of the application (db, web api and client) and each has similar logic in it (ie. validation). I was wondering if there is an approach that would allow me to write a model file (say in ruby), and then have it convert that model into the necessary c# files. Currently it seems

spring integration dsl filter instead filter method annotation

问题 How can I switch from filter annotation method to Spring integration java DSL filter. how can I call filter method? IntegrationFlows.from("removeSession") // remove chat session from user sessions map .handle("sessionLogService", "removeChatSession") // continue and remove user from ehcache only if user have no more opened sessions. .filter(/* what's going here? */) .get(); instead Filter annotation. @Filter(inputChannel = "userGoOfflineFilter", outputChannel = "userGoOffline") public boolean
