FAQ

Does fortitude handle preprocessor files?

fortitude uses the tree-sitter Fortran grammar to parse your source code, and currently this has some support for the preprocessor -- essentially limited to #include, and #if and #ifdef guards around complete statements or constructs.

However, tree-sitter is fairly error tolerant, and fortitude should still run fine, you might just get spurious syntax errors. You can ignore these project wide with --ignore=E001.

What is "preview"?

Preview enables a collection of newer rules and fixes that are considered experimental or unstable. See the preview documentation for more details; or, to see which rules are currently in preview, visit the rules reference.
