Just-in-time compilation of Fortran code in Python via [f2py](https://numpy.org/doc/stable/f2py/).
Check out the [documentation](https://coslo.frama.io/f2py-jit/) for full details.
Quick start
-----------
Start from a piece of Fortran `code.f90`
```fortran
subroutine hello()
print*, "Hello world!"
end subroutine
```
Compile the code, import it and execute it
```python
from f2py_jit import jit
f90 = jit('code.f90')
f90.hello()
```
Do the same but from a python string containing the source block
```python
source = """
subroutine hello()
print*, "Hello world!"
end subroutine
"""
f90 = jit(source)
f90.hello()
```
If the Fortran source contains multiple subroutines calling each other, `f2py` will not perform interprocedural optimizations (at least not by default). `f2py_jit` can inline the source code before compiling it, and you will get a [performace boost](https://coslo.frama.io/f2py-jit/tutorial/#performance) [**This feature is experimental**]
```python
f90 = jit('code.f90', inline=True)
```
Features
--------
- Compilation of Fortran source blocks as Python strings
- Caching of module builds across executions
- Support for Fortran derived types via f90wrap
- Inlining to improve performance (experimental)
Dependencies
------------
- `numpy`
- Fortran compiler (ex. `gfortran`)
The package currently supports Python versions from 3.7 to 3.13.
Note that Python versions >= 3.12 will use the `meson` backend to build Fortran extensions, which has slower build times than `distutils` (used by default in versions < 3.12).
Installation
------------
From pip
```
pip install f2py-jit
```
To install the package with support for derived types (courtesy of `f90wrap`)
```
pip install f2py-jit[types]
```
Note that this requires Python >= 3.8.
From source
```
git clone https://framagit.org/coslo/f2py-jit.git
cd f2py_jit
pip install .
```
