A Fortran Static Analyzer
The idea of this library is to enable users to write their own tool to handle Fortran source files. Some examples:
-
Reformat a Fortran file For example have all keywords upper case, all variables lower case.
-
Add implicit none (and all missing variables declations to a source file).
-
Study code in maths mode, e.g.:
DO j = 1, veg_pts
l = veg_index(j)
o3mol(l)
flux_o3(l) = --------------------
ratio_o3
ra(l)+ ----------
gl(l)
rd(l) = rd(l)*fo3(l)
END DO
+-----------+
fo3(l) = -0.5*b+0.5*\| b*b-4.0*c
+-----------------------------+
-b2(l) | b2(l) * b2(l) b3(l) |
wp(l) = --------- -\ | --------------- - -------
2*b1(l) \| 4*b1(l)*b1(l) b1(l)
0.8
km_dsct_factor(i,j) * z_pr
0.75 * rho_tq(i,j,k-1) * v_top_dsc(i,j) * g1 * vkman * ((1.0- ---------------------------- )^ ) * z_pr * z_pr
zh_pr
rhokm_top(i,j,k) = rhokm_top(i,j,k)+ ------------------------------------------------------------------------------------------------------------------
zh_pr
- Automatically modify a subroutine so that it will write all input variables at the beginning and all output variables at the end into a file. Then create a driver which reads the input data, calls the subroutine, and compares the result. This can be used for example to unit testing, or help in optimising subroutines.
At this stage this is pretty much work in progress, but e.g. maths mode already works:
PYTHONPATH=. bin/MathsMode.py my_fortran_file.F90
