Promula

Mon, 01 Jan 0001 00:00:00 +0000

Promula — also known as gmFortran and shipped by Great Migrations — is the Fortran translation, preprocessing, and modernisation toolset we work in daily. We have used it on real engagements to lift legacy Fortran into a maintainable, testable, modern shape, and to extend production codebases with multi-line strings, hash maps, regex, SQL, and other modern conveniences without throwing away any existing logic.

Where we add value

Driving Promula / gmFortran on production codebases, not toy examples.
Adopting it in an existing Fortran codebase without disrupting the build.
Configuring rules and exceptions for the quirks every old codebase has.
Combining tool output with hand-tuned changes so the result reads like code humans want to maintain.
Wiring the translation into reproducible builds, CI, and unit-test pipelines so the migration is repeatable instead of a one-shot stunt — see Expertise → 32 → 64-bit migration.
Coordinating with Great Migrations when an engagement needs both the toolmaker and an experienced delivery team.
Training your team on Promula idioms so the codebase stays maintainable after we leave.
