STB
Compile-time conversion library, from IDA-style string to array (supports wildcarding).
How to use
Step 1:
git clone https://github.com/cristeigabriel/STB.git
Step 2:
Include include/stb.hh to your project.
Step 3:
Either create a custom conversion type with stb::basic_hex_string_array_conversion or use stb::hex_string_array_conversion (whitespace delimiter, question-mark wildcard, -1 wildcard value) (short alias: stb::simple_conversion).
Example:
stb::simple_conversion::build<stb::fixed_string {"AA BB CC DD EE FF"}>::value
// stb::simple_conversion::build<"AA BB CC DD EE FF">::value also works
You may also create a sanitary macro that looks something like:
#define CONV(x) stb::simple_conversion::build<stb::fixed_string {X}>::value
then do:
CONV("AA BB CC DD EE FF")
How this works
We pass a stb::fixed_string to a conversion type's build, we run make on it, we ensure constant evaluation through stb::consteval_value on make which itself calls parse::get then does some logic utilizing the information and detail, we store the result of make in value inside the build instance.
Results
This leaves no trace in the binary by ensuring constant evaluation (doesn't require consteval) of conversion string parser and conversion builder.
Compile times
This should go in a pre-compiled header. You may also disable compliance verifications by defining STB_OMIT_TESTS before include.
