There are a number of different places in Opus that you can use the evaluator. Most are optional - the evaluator can be used to augment or extend a simpler system - but some functionality requires its use.
- define file information columns that use the evaluator to generate their contents.
- configure custom rules for that extend or replace the built-in rules.
- and the both let you write evaluation expressions which can be used to select files for operations or return them as part of the search. You can also enter evaluation code directly into the when it's set to use Opus Find.
- insert text into that's generated by the evaluator.
- many can use the evaluator, labels and icons can be changed dynamically, and command lines can contain inserted text (or even be generated completely) using the evaluator.
- insert text from the evaluator into the new filename.
- define Ctrl key sequences for that use the evaluator to select, replace or delete text, or to move the cursor.
- insert evaluator-generated text into the status bar.
- the evaluator has special support for column header context menus, so that you can make dynamic menus that change depending on which column was clicked.
- the evaluator has special support for folder tab context menus, so that you can make dynamic menus that change depending on which tab is clicked or how many tabs are open.
