identifier case mismatch

Identifier case mismatch (identifier-case-mismatch)

A name is spelled in a different case from its declaration. Delphi does not care, so this is a readability rule, and also a way to catch code that was never read after a rename. OFF by default.

Running it

drag-lint lint <file> --rule identifier-case-mismatch
drag-lint lint-all --db <project.sqlite> --rule identifier-case-mismatch

What it covers

• Locals and parameters, from the syntax tree, so no index is needed.
• With an index: every ref the resolver bound to a project symbol (methods, properties, routines), across units.

One finding per spelling per routine for locals, and one per spelling per symbol per file for bound refs, so a legacy file does not produce one line per use.

What stays silent

• Anything inside with: a bare name may be a member there.
• A name after a dot, unless the resolver bound it.
• A local declared twice in different spellings (two inline blocks).
• A nested routine's use of an outer local: the nested routine is judged on its own declarations.
• A ref the resolver did not bind, and names from the platform library.
