ctfp (Compile-Time Find-Pattern)

ctfp is a small, header-only C++ library that allows you to build signatures at compile-time.

Example Usage

#include <ctfp/ctfp.h>

int main() {
    const auto result = ctfp::find<"aabbccdd?">(haystack);
    // Do something...
    return 0;
}

Building

ctfp requires a C++23-compatible compiler.

target_link_libraries(my_project PRIVATE ctfp::ctfp)

Format

The pattern format is rather straightforward: each byte in the pattern string must always match, whereas a wildcard (represented by a single '?') matches any byte.

For example, the pattern "aabbccdd?" states that the following must be true:

The first byte is 0xAA,

The second byte is 0xBB,

The third byte is 0xCC,

The fourth byte is 0xDD,

The fifth byte may be anything.
