Changelog of @hackage/fortran-src 0.3.0

0.3.0 (June 13, 2019)

• 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.
