Cling actually works by compiling interactively, it's more of a JIT compiler than an interpreter. Unicorn Meta Zoo 9: The basic strategy in scripting is to sacrifice program efficiency for programmer efficiency. For example, the UNIX philosophy is that shell scripts are used to build applications out of small specialized programs.

Generally, such programs will be slower than optimized compiled code, but they are executed immediately.

It's usually called eval and it is tremendously powerful. Yes, undderc the CPP stuff and templates were all part of the language being interpreted. There has been a surprising amount of scripting using C-like languages in recent years. Sometimes these languages are called typelessbut it's more accurate to call them dynamic typingor tolerant typing.

CINT is a prime example of something you have to install when all you want to do is read in a data file. Here is nice Google Talk: These days, I think a debugger like GDB is basically just as good.

So, testing small programs becomes faster. The glue doesn't need to be fast because it's assumed that the components encapsulate all serious processing. There has been a resurgence in scripting languages, which are informal, very high-level languages that make programmers more productive. We sacrifice strong type-checking and some efficiency for a simple no-nonsense style that does the job.

Generally, the use of dynamic evaluation prevents scripting languages from being directly compiled as an executable.

The pipe symbol, which we would like to represent by operatorhas unfortunately got the wrong associativity, so we have to use operator instead.

Static typing, for example, buys you great gains in optimization during compilation, but mostly serves to clutter and over-constrain your code if the computer is only allowed to see it at runtime.

There is a program called c-repl which works by repeatedly compiling your code into shared libraries using GCC, then loading the resulting undec. My point isn't that CINT is worse than everythingonly that there are many things which would be better. In some applications, it can be useful to strengthen the type system even further as C. The game is the undetc, whether the players are barefoot in the yard unrerc under the stadium lights.

Classes must at least have well-defined interfaces because there is no dynamic dispatch in the language. This is a good deal easier than the usual equivalent, and it compares well to the version in other scripting languages. It was pretty nice, although it couldn't handle things like bitfields or fancy pointer mangling. My question here is this: With extreme programming, all code is created with the appropriate unit tests that will catch badly behaved arguments.

In this article, I discussed what is meant by scripting, in both its micro small utilities and macro glue for system integration meanings. These tests are stronger than the formal guarantees of strong typing, so you may as well put your energy into strong testing, rather than strong typing.

UnderC C++ Interpreter

A local Unix guru was working at a company in which a programmer needed to search for certain patterns at the end of a log file.

Those in the younger generation either follow this lead or use Python for scripting. It has a complex syntax, subtle semantics, and a fearsome reputation; and it's slow to compile optimally. What would the interpreter do when it encountered a template instance?

Sergei I don't know if I understand you: The Pragmatic Programmer, 20th Anniversary Edition —revised, updated, c++ available now! Or to be more realistic the project lead can enforce a style appropriate to the project, without being constrained by linguistic prescription. CINT is more of a true interpreter, so large source files are loaded very quickly, but with the clever twist that any repeated execution causes the loop and any called functions to be translated into pcode.

The term scripting actually covers both specialized languages such as AWK which is not extendable and extendable glue languages.
