Serialization Schema

Path

namespace schema.internal;

table Path {
    pathname:string (key);
    last_write_timestamp:uint64;
}

• Path is used when we want to verify the physical presence of a particular file

• The last_write_timestamp is used to check if we need to rebuild the file.

• However we can use different rebuild strategies in the future. Ex: last_write_timestamp:uint64 can be converted to hash:string

Generator

namespace schema.internal;

// Each generator consists of many relational files of [input] - [output] - [commands]
table Generator {
    name:string (key);
    inputs:[Path];
    outputs:[string];
    commands:[string];
}
root_type Generator;

Target

namespace schema.internal;

enum TargetType : byte {
    Executable,
    StaticLibrary,
    DynamicLibrary
}

// TODO, Check if Toolchain needs to be added to Target
table Target {
    // Metadata
    name:string (key);
    type:TargetType;

    // Input
    // Files
    source_files:[Path];
    header_files:[Path];
    pch_files:[Path];
    lib_deps:[Path];

    // Links
    external_lib_deps:[string];

    // Directories
    include_dirs:[string];
    lib_dirs:[string];

    // Flags
    preprocessor_flags:[string];
    common_compile_flags:[string];

    pch_object_flags:[string];

    link_flags:[string];

    // Additional dependencies

    // Output

    // State
