fuuid4

Fortran module to generate random (version 4) Universally Unique Identifiers (UUIDs). Fuuid4 can either wrap the libuuid generator, or use the bundled Mersenne Twister psuedo-random number generator (PRNG) to generate UUIDs itself.

Requirements

Fuuid4 requires a Fortran 2008 compliant compiler and, optionally, libuuid.

Installation

There are a few ways you can use fuuid4 in your project.

Single file inclusion

Perhaps the easiest way is to copy src/fuuid4.f90 into your project and build it as part of your package. The downside to this approach is that you will have to apply any updates manually.

There is a single point of configuration: the preprocessor macro FUUID4_HAS_LIBUUID. If this is defined to be 1, then fuuid4 must be linked against libuuid. If it is 0 or undefined, then fuuid4 uses its internal PRNG instead.

External library

You can build fuuid4 into a library using CMake:

$ cmake . -B build
$ cmake --build build

You can then use the built libraries under build/lib and the .mod file under build/mod. You can install these somewhere convenient with:

$ cmake . -B build -DCMAKE_INSTALL_PREFIX=/path/to/install
$ cmake --build build --target install

fuuid4 installs configuration files for CMake, so you can include fuuid4 in your CMake project with:

find_package(fuuid4)

target_link_libraries(<your target> PRIVATE fuuid4::fuuid4)

You can point CMake at either the install location or the build directory directly with -Dfuuid4_ROOT=/path/to/install/or/build/dir

Internal target in CMake

You can use fuuid4 directly in a CMake project with FetchContent like so:

include(FetchContent)

FetchContent_declare(fuuid4
    GIT_REPOSITORY https://github.com/PlasmaFAIR/fuuid4.git
    GIT_TAG v0.1.0)
FetchContent_makeavailable(fuuid4)

target_link_libraries(<your target> PRIVATE fuuid4::fuuid4)
