A programming language for generating code.

tg

A programming language for generating code.

Example

Given a generator file like this:

generator hello() {
    Hello World!
}

hello();

This will print Hello World!.

A better example:

generator better_enum(enum_name: string, fields: string[]) {
    enum ${enum_name} {
        $for (field in fields) {
            ${field}${,}
        }
    };

    static char const * const ${enum_name}_strings[] = {
        $for (field in fields) {
            "${field}"${,}
        }
    };
}

better_enum("test", ["first", "second", "third"]);

This will print:

enum test {
    first,
    second,
    third
};

static char const * const test_strings[] = {
    "first",
    "second",
    "third"
};

Compiling

You first require a modern C++ compiler that supports C++17.

Easiest building method would be to use GNU make version >= 3.82 and issuing the following command in the root of the repository:

make BUILD=release

This will build an executable in the build/release directory. Building without BUILD=release will create a debug executable by default. You can change which compiler to use like this:

make BUILD=release CXX=gcc-8

On windows you should do this from a developer console or use this command:

PATH_TO_YOUR_VCVARSALL/vcvarsall.bat x64
make BUILD=release CXX=cl

Since this project uses a unity build (one single translation unit) you can also simply build src/main.cpp directly with a similar command to either of these:

g++ src/main.cpp -Iextern -Isrc -o build/release/tg.out -std=c++17 -O3

PATH_TO_YOUR_VCVARSALL/vcvarsall.bat x64
cl src/main.cpp -Iextern -Isrc -Febuild/release/tg.exe -std:c++17 -O2 -EHs -nologo
