DUX-5350 Don't eval modules with no eval commands#458
Merged
Conversation
In #454 I restructured the eval command logic. Before, the loop looked like this: ```rust for (path, commands) in eval_commands_by_path { for command in commands { do_eval_command(command); } } ``` After, I pulled some logic out of the inner loop: ```rust for (path, commands) in eval_commands_by_path { do_common_logic(path); for command in commands { do_eval_command(command); } finish_common_logic(path); } ``` But sometimes `commands` was empty, doing unnecessary work in the best case and attempting to eval non-Haskell in the worst case! Let's skip empty entries.

To actually _execute_ eval commands with the proper bindings in scope, we need to be able to evaluate (interpret) a file, which requires we know its module _name_ (because `:module + *MODULE_NAME` only supports module names and not source paths). Let's guard adding an entry to the `eval_commands` map by making sure we can convert the path to a module name. See also: #458, #454. - [ ] Updated the user manual in `docs/`. - [x] Added integration / regression tests in `tests/`.
