Ray And Martin English Grammar Book

[Oliver Parkes]

WrenMartin refers to a single book High School English Grammar and Composition or collectively, a series of English grammar textbooks written jointly by P. C. Wren and H. Martin.[1] Written primarily for the children of British officers residing in India, these books were widely adopted by Indian and Pakistani schools in the post-colonial era and missionary schools in Burma. The books were published in 1935, with a discussion on composition added later. The content in the books is largely based on The Manual of English Grammar and Composition by J. C. Nesfield.

Other books in this series are Elementary English Grammar, A First Book of English Grammar and Composition, High School English Grammar and Composition and A Final Course of Grammar & Composition. The series of textbooks is still in use at many Indian schools. While semantic change has dated the original books, they continue to enjoy considerable popularity and updated versions are now in common use. Copies of the different versions of this series are available online.[2]

Martin Luther Grammar School and Immanuel Academy teach children in the way that they were created to learn. We teach your students in the same way the ancient Greeks and Romans taught their children, how the Reformers of 500 years ago taught their children, how the American founding fathers were taught.

You've heard of the Three Rs: Reading, Writing, and Arithmetic. That's what you will see at MLGS. The arts of language include Grammar, Logic, and Rhetoric. The arts of mathematics includes arithmetic, music theory, geometry, and astronomy. Our grammar school prepares scholars for our academy, where they study higher math, more science, ask questions and connect concepts, and learn how to speak and write winsomely.

"Classical Lutheran education seeks to cultivate in students self-knowledge, tools for learning, the ability to contemplate great ideas, and an understanding of the world in which he lives -all for the love and service of others. Above all, classical and Lutheran education inclines a child toward truth, goodness, and beauty found fully and eternally in the person and work of Jesus Christ. This is most certainly true."

Non-discrimination Statement: Martin Luther Grammar School admits students of any race, color, national and ethnic origin to all the rights, privileges, programs, and activities generally accorded or made available to students at the school. It does not discriminate on the basis of race, color, national and ethnic origin in administration of its educational policies, admissions policies, scholarship and loan programs, and athletic and other school-administered programs.

Classical Education reflects the natural intellectual development of children as well as the pattern through

which all human learning progresses. Students first gain a foundation of basic knowledge (grammar stage), subsequently learn to reason for deeper understanding (logic stage), and finally concentrate on developing and defending their ideas (rhetoric stage). Through this classical method of instruction (called the Trivium), students are taught to be interested listeners, critical thinkers, and persuasive communicators all their lives.

Martin Luther Grammar School provides a classical education curriculum for Kindergarten through the 5th Grade. We seek to put into practice the ideals of Classical education by utilizing curricular materials consistent with those ideals. These include:

For a long time there's been a style of software developmentthat seeks to describe software systems using a collection ofdomain specific languages. You see this in the Unix tradition of'little languages' which generate code via lex and yacc; you seeit in the Lisp community with languages developed inside Lisp,often with the help of Lisp's macros. Suchapproaches are much liked by their advocates, but this style ofthinking hasn't caught on as much as many of these people wouldlike.

In the last few years there's been an attempt to support thisstyle of development through a new class of software tool. Theearliest and best known of these is Intentional Programming -originally developed by Charles Simonyi while atMicrosoft. However there are other people doing similar thingstoo, generating enough momentum to create some interest in this approach.

At this point I'm going to coin some terminology that I'll usein the rest of this essay. As usual there's no standardterminology in this field, so don't expect the terms I use to beused in this style elsewhere. I'm going to give a brief definitionhere, but will explain much more about them as the essay goes on -so don't worry if you don't follow the definitions immediately.

The two main terms I'm specifically coining for this articleare 'Language Oriented Programming' and 'Language Workbench'. I useLanguage Oriented Programming to mean the general styleof development which operates about the idea of building softwarearound a set of domain specific languages. I use LanguageWorkbench as a generic term for this new breed of tools. So alanguage workbench is one way to do language oriented programming. Youmay also be unfamiliar with the term Domain SpecificLanguage (usually abbreviated to DSL). It is alimited form of computer language designed for a specific class ofproblems. Some communities like to use DSL only for problem domainlanguages, but I'm following the usage that uses DSL for any limiteddomain.

I'm going to start by briefly describing the current world oflanguage oriented programming with an example, an overview of thedifferent flavors, and various arguments about the pros and consof the approach. If you're familiar with language orientedprogramming you may want to skip through this stuff, but I'vefound that many, indeed most, developers aren't that familiar withthese ideas. Once these are explained I'll then build on them toexplain what language workbenches are and how they alter thetrade-offs.

As I wrote this article, it turned out to be too much for asingle article, so I've separated some parts of the discussion intoother articles. I'll mention as I go in the text where it makes senseto go off an read those, they're also linked just below thecontents. In particular take a look at the example using MPS - this shows an exampleDSL built using one of the current language workbenches and isprobably the best way of getting a feel for what they will belike. You'll need to get through the general description of languageworkbenches here before it'll make much sense.

I'm going to begin by running through a very simple exampleof language oriented programming and the kind of situation that leadsto it. Imagine we have a system that reads files and needs to createobjects based on these files. The file format is one object per line.Each line can map to a different class, the class is indicated by afour character code at the beginning of the line. The rest of the linecontains the data for the fields of the class, these vary depending onwhat class we are talking about. The fields are indicated by positionrather than delimiter. So a customer ID number might run fromcharacters 4-8.

The dots indicate some mumbly uninteresting data. The commentline at the top is to help you see the character positions. Thefirst four characters indicate the kind of data - SVCL indicatesa service call, USGE a record of usage. The characters afterthat represent the data for the object. So the characters fromposition 5 to 18 on a service call indicate the name of the customer.

To turn these into objects you might be tempted to writespecific code for each case, I hope that after a few you'd want tosimplify the task by writing a single reader class that you canparameterize with the details of the fields for each class.

Here I have a simple class to do this. A reader class readsthe file. A reader can be parameterized with a collection ofreader strategy classes - one for each target class. So for ourexample we'd have one strategy for service calls, another forusages. I hold the strategies in a map keyed by the code.

It just loops through the lines, reads enough to figure outwhat strategy to call, and then hands over to the strategy to dothe work. To get the reader to do the job you create a newreader, load it up with strategies and let it loose on the filesyou want to process.

The strategies can also be parameterizable. We onlyneed one strategy class, when we instantiate it we canparameterize it with the code, target class, and details of whatcharacter positions on the input map to which fields on thetarget class. I hold the latter in a list of field extractor classes.

So far what I've described is a very simple library for doingthis kind of thing. Essentially I've built an abstraction whichI can then use to specify the concrete work. To use theabstraction I need to configure the strategies and load them intothe reader. Here's examples of this for the two examplecases.

I look at this as two different styles of code. TheReader and Strategy classes are an abstraction, this last bit ofcode is configuration. When you're building these kinds of libraryclasses it often helps to think of these two pieces: abstractionand configuration. The abstraction may be a class library, aframework, or just a set of function calls. The abstraction maybe reusable in many projects, but it doesn't have to be. Theconfiguration code tends to be specific; rather simple, straight-ahead code.

Since the configuration is pretty simple and likely to changemore often than the abstraction, a common approach is toseparate it further and take the configuration out of C#altogether. The current fashion is to put it in an XML file.

As you look at this last example, you can see that what wehave here is a very small programming language - one that's suitable(only) for the purpose of mapping fixed length fields into classes.It's a classic example of the Unix tradition of 'little languages'. It is aDomain Specific Language for the task.
