Tamarin Visual Studio Code extension

A Visual Studio Code extension for Tamarin files (.spthy) based on giclu-3's extension and using Tamarin's tree-sitter grammar.

Features:

• Enhances giclu-3's syntax highlighting.

• Adds comprehensive syntax error detection based on the grammar with MISSING or ERROR messages.

• Provides various wellformedness checks:

  • Checks position and usage of reserved facts (Fr, Out, In, K, KD, KU).
  • Checks whether variable are used consistly inside a rule, i.e., using the same capitalization and sort.
  • Spellcheck on facts (must start with an uppercase letter).
  • Checks whether all variables in the conclusion of a rule appear in the premises (except public variables).
  • Checks the arity of facts and functions.
  • Checks whether a lemma uses free terms.
  • Checks whether all facts in the premises of the rules appear in the conclusion of some (other) rule (provides a quick fix by using the closest exisiting fact, based on editing distance).
  • Checks wether all variables in the right hand side of a macro are in the left hand side or public.
  • Checks wether all variable in the right hand side of an equation are in the left hand side.
  • Provides a quick fix for function names (suggestions based on editing distance).
  • Checks wether built-ins are imported when encountering corresponding functions or symbols (provides a quick fix to import the right built-in).

  This is a subset of the checks performed by Tamarin. For more details on Tamarin's wellformedness checks, see the corresponding Tamarin Prover manual section.

• Use right click and Rename on an indentifier to rename all occurences of it inside a rule or a lemma.

• Use right click and Search Definition on facts or function names and press CTRL+TAB to navigate through all occurences.
