CI-ADDO-EN: Infrastructure for the Production of Languages

为回应用户的强烈需求，PLT基础设施项目旨在为PLT计划的软件基础设施配备四个关键组件。第一个目标是减少PLT方案目标代码的运行时间；PI打算通过添加即时编译器来实现这一点。第二个目标要求增强在PLT方案中嵌入外来代码的能力，反之亦然；该计划要求实现一个动态的外来函数接口，允许程序员以增量的方式开发和嵌入C代码。该项目的第三个目标是将软件库的网络存储库直接集成到编程语言中。目标四是帮助教育用户(初中、高中、大学和一些研究生课程)增加教学图书馆；为此，PI正在设计一个框架，将特殊用途的函数式语言插入PLT计划框架。

In response to a strong demand from its users, the PLT infrastructure project aims to equip the PLT Scheme software infrastructure with four key components. Objective one is to reduce the running time of PLT Scheme object code; the PIs intend to accomplish this with the addition of a just- in-time compiler. The second objective calls for an enhanced ability to embed foreign code into PLT Scheme and vice versa; the plan calls for the implementation of a dynamic foreign function interface that allows programmers to develop and embed C code in an incremental manner. The project's third objective is to integrate a web repository for software libraries directly into the programming language. Objective four is to assist educational users (middle schools, high schools, colleges, and some graduate courses) with additional teaching libraries; to this end, the PIs are designing a framework for plugging special-purpose functional languages into the PLT Scheme framework.
