fortran-src v0.3.0 Release Notes

Release Date: 2019-06-13 // almost 5 years ago
    • ➕ Add partial Fortran2003 support.
    • Introduce datatype for BBGr instead of prior type alias for Gr.
      • Now split into three fields: bbgrGr, bbgrEntries and bbgrExits
      • May require refactoring of code to use bbgrGr field where a Gr was expected before.
    • Introduce pragmaOffset field for Position, allowing pragmas to specify an apparent file and line-number.
      • May require refactoring of code that uses the Position constructor.
      • Fifth field is Maybe (Int, String), containing a line-offset and a target filename when present.
      • It's designed such that most Position-based transformations are not affected by the pragmaOffset.
      • They may need to preserve the field, though, as it passes through functions.
      • Default value is 'Nothing'.
    • ➕ Add --show-flows-to/--show-flows-from features
      • Visualise the dataflow use/def chains using GraphViz.
    • ➕ Add --show-block-numbers feature.
      • Allows user to get AST-block numbers easily in order to use them with the above visualisation features.
    • 🛠 Fix several bugs with dataflow analysis that had accumulated.
    • Eliminate StContinue and StEnddo are eliminated during GroupLabeledDo transformations.
      • To be consistent with unlabeled Do.
    • 📜 Parse and discard C-comments as a convenience feature for when fortran-src must interact with the output of C preprocessors that insert spurious comments.
    • ➕ Add type propagation into type analysis, annotating every expression with a type.
      • Additional interface: analyseTypesWithEnv to access a list of type errors found.
    • ➕ Add dimensional information to CTArray and length/kind to TypeCharacter.
    • Stricter checking of the grouping transform - if any statements that should be grouped are not grouped, raise an error.
    • 👌 Support pragmas that alter the current 'filename and position' tracker, often used by preprocessors to help pinpoint original code locations.
      • Uses a relative offset field called 'posPragmaOffset' so that relative measures continue to function correctly.
    • ➕ Add constant propagation / parameter variable analysis.
    • ➕ Add -c feature to compile 'fsmod files' with renaming and type info.
