Petaca is an ad hoc collection of modern Fortran modules that provide broadly useful capabilities -- things that I have found myself using repeatedly across many projects. A unifying feature of the modules is their object-oriented interfaces and implementation.

Read the documentation on readthedocs.org (under development).

The compilers currently supported/tested are:

• NAG nagfor 7.0, 7.1, and 7.2 (recent builds of those versions)
• GNU gfortran 12 and 13
• Classic ifort from Intel OneAPI 2023.2 and 2024.0
• LLVM-based ifx from Intel OneAPI 2024.0 and 2024.1

Other compilers supporting the Fortran 2018 standard should work as well.
