Topic: Larch family


  
  Larch family - Wikipedia, the free encyclopedia
The Larch family of formal specification languages are intended for the precise specification of computing systems.
The Larch family was developed primarily in the United States in the 1980s and 1990s, involving researchers at Xerox PARC, DEC/SRC, MIT, and other places.
Unlike the Z notation, the Larch family has one language for algebraic specification of abstract data types (LSL, the Larch Shared Language), and a separate interface language tailored to each language in which programs are to be written (Modula-3, C, Smalltalk, etc.).

 Larch Frequently Asked Questions (comp.specification.larch FAQ) FAQ
The Larch family of specification languages [Guttag-Horning-Wing85b] consists of all the BISLs that use LSL for specification of mathematical vocabulary.
The main difference between LSL and a Larch BISL is that in LSL one specifies mathematical theories of the operators that are used in the pre- and postcondition specifications of a Larch BISL.
In comparison to Larch family BISLs, the first thing to note is that VDM-SL is not a BISL itself, as it is not tailored to the specification of interfaces for some particular programming language.

Larch and the Larch Family of Languages In this chapter, we discuss global questions about Larch.
Another problem with this comparison is that Larch has two tiers, but VDM-SL [Jones90] [ISO-VDM96] [Fitzgerald-Larsen98], Z [Hayes93] [Spivey92], and COLD-K [Feijs-Jonkers92] are all integrated languages, which mix aspects of both of the tiers of the Larch family.
Although you can use the Larch languages and tools without subscribing to any particular view on the utility of formal methods, there is an emerging view of this question in the Larch community.

 Re: Where to get FAQ??
The Larch family of languages The Larch family of languages supports a two-tiered, definitional style of specification.
The former kind are Larch interface languages, and the latter is the Larch Shared Language (LSL).
At that time, we proposed a combination of algebraic and operational specifications which we referred to as "dyadic specification." By 1980 we had evolved the essence of the two-tiered style of specification; the term "two-tiered" was introduced by Jeannette Wing in her 1983 Ph.D. thesis (MIT).

In addition, the Larch interface languages have three parts for specifying procedural abstraction: header, traits with theory of operators, and a body of routine effects.
The Larch family of languages is a powerful set of specification languages for software reuse of abstract data types.

Par 1 is a formal Request for Discussion on the creation of an unmoderated newsgroup for discussion of issues related to the Larch family of formal specification languages, and related methodologies.
Discussions on the Larch mailing list are most frequently technical in nature, specific to Larch, and uninteresting to the other comp.specification readers.
Hence, to put this on the general newsgroup would be unfair to other participants in the general newsgroup, as well as being unfair to other specification methodologies (and their proponents) that might be lost among the Larch discussion.

 The Cider House Rules: On-Line Review by Christian Leopold Shea.

 Report on the Larch Shared Language Version 2.3 - Guttag, Horning, Modet (ResearchIndex)
Abstract: The Larch family of languages is used to specify program interfaces in a two-tiered definitional style.
Each Larch specification has components written in two languages: one that is designed for a specific programming language and another that is independent of any programming language.
The former are the Larch interface languages, and the latter is the Larch Shared Language (LSL).

 3 Preliminary design of Larch/Java
The peculiarity of Larch with respect to design specifications is the ``two tiers'' (or layers) approach it uses.
The lower tier is the Larch Shared Language, an algebraic specification language which defines the mathematical abstractions used in the other tier, which is the behavior interface language in which predicate on pre and post condition over the execution of the operations are defined [
For common data structures like integers, sets, etc, Larch provides a collection of library traits, which can be reused to specify new objects or abstract values of some data type.
