Renames and indent-changes in big projects

[Gener4tor]

When I try to rename a function which is used in a lot of forms or I use the indent-feature with "current project" access runs into memory problems and the rename (and the indent) is only half done.

Thanks for reporting. How large is the project? Is logging enabled, do you have any interesting log entries?

The indenter and the rename refactorings are two completely unrelated components, probably best to address them separately.

The indenter iterates each module sequentially and temporarily stores (and returns) an array of strings containing the entire module's raw code (no parsing involved). How large a module are we looking at? Note that VBA will refuse to compile anything exceeding 10K lines of code.

Refactor/rename iterates all references to the selected identifier/declaration (this requires full parsing and resolving of all modules), and proceeds to replace the corresponding tokens in each module's lexer token stream, using a TokenStreamRewriter that creates a "rewriter program", with each token replacement as a single step. If the operation completes for all modules, each rewriter program is then executed for each individual module (again, sequentially), and each module's content is fully replaced in a single operation, which preserves as much of the VBE's undo stack as possible (Ctrl+Z once clears the module, Ctrl+Z twice reverts to pre-rewrite state).

Rubberduck is RAM-heavy (see #3347), which is quite possibly more of a problem in a more limited 32-bit host.
