Expression templates can also accelerate C++ automatic differentiation implementations, [12] as demonstrated in the Adept library. Outside of vector math, the Spirit parser framework uses expression templates to represent formal grammars and compile these into parsers.
The Template:Weather box/concise_C (Celsius) uses {{Weather box}} to generate a climate table, by using 36 positional parameters. Other parameters are: location=, source= and optional "accessdate=" or sctemp=t. The 36 parameters are: 12 monthly highs (C), 12 lows (total 24) plus an optional 12 monthly rain/precipitation (in mm). Example of coding:
In formal language theory, a context-free grammar (CFG) is a formal grammar whose production rules can be applied to a nonterminal symbol regardless of its context ...

The ROSE compiler framework, developed at Lawrence Livermore National Laboratory (LLNL), is an open-source software compiler infrastructure to generate source-to-source analyzers and translators for multiple source languages including C (C89, C99, Unified Parallel C (UPC)), C++ (C++98, C++11), Fortran (77, 95, 2003), OpenMP, Java, Python, and PHP.
A generic unit is a package or a subprogram that takes one or more generic formal parameters. [18] A generic formal parameter is a value, a variable, a constant, a type, a subprogram, or even an instance of another, designated, generic unit. For generic formal types, the syntax distinguishes between discrete, floating-point, fixed-point, access ...
Chicken Scheme compiler, a Scheme to C compiler that uses continuation-passing style for translating Scheme procedures into C functions while using the C-stack as the nursery for the generational garbage collector; Kelsey, Richard A. (March 1995). "A Correspondence between Continuation Passing Style and Static Single Assignment Form".
In computing, compiler correctness is the branch of computer science that deals with trying to show that a compiler behaves according to its language specification. [ citation needed ] Techniques include developing the compiler using formal methods and using rigorous testing (often called compiler validation) on an existing compiler.
