A language may also be defined by an interpreter in which the semantics of the host language is given.
12.
Thus, the parser is " directly encoded " in the host language similar to recursive descent.
13.
The first host languages used were logic programming languages, so the field was initially called " constraint logic programming ".
14.
The most common host languages are Prolog, C + +, and Java, but other languages have been used as well.
15.
Prolog is by far the most popular host language and CHR is included in several Prolog implementations, including C, and JavaScript.
16.
In the former case, the constraint store can be read off by a host language program to look for facts of interest.
17.
OMeta is noted for its use in creating meta languages, requires a host language; it was originally created as a COLA implementation.
18.
OMeta can theoretically be implemented into any host language, but it is used most often as OMeta / JS, a JavaScript implementation.
19.
Alliance Francaise, Trivandrum established in the early 80's, hosts language classes, cultural exchange programs, film festivals and other cultural events.
20.
A language designed with a meta-circular implementation in mind is often more suited for building languages in general, even ones completely different from the host language.
