CPreprocessorIf[cond]

is a symbolic representation of a preprocessor if conditional.

CPreprocessorIf[cond,true,false]

represents the true and false cases.

Details and Options

SymbolicC expressions are inert; they evaluate to themselves, staying in an unevaluated form.
SymbolicC expressions can be converted into a C string with ToCCodeString.

To use SymbolicC you first need to load the package:

Wolfram Language code: Needs["SymbolicC`"]

This creates a preprocessor if conditional directive:

Wolfram Language code: CPreprocessorIf["DEBUG"]//ToCCodeString

This creates an entire if/else/endif set of statements:

Wolfram Language code: CPreprocessorIf["DEBUG", CAssign["a", "true"], CAssign["a", "false"]]//ToCCodeString

This adds a comment to the if directive:

Wolfram Language code: CPreprocessorIf[{"DEBUG", CComment["debug code", " "]}, CAssign["a", "true"], CAssign["a", "false"]]//ToCCodeString
