You can experiment with the evaluator using the CLI tool.
Open it via Opus CLI / Ad-Hoc Script Editor in the main window's Tools menu. At the bottom of the CLI, turn on Script Interpreter and use the drop-down to select Evaluator as the language.
Here's the code in the screenshot in a format you can copy and paste:
str = "Text in a string"; Output(Match(str, "^text.*string$", "r")); Output(Match(str, "^text.*str$", "r")); Output(" "); name = "Job-19230-20230605-XE.xlsx"; Output(jobdate = RegEx(name, "Job-(.+)-(.+)-(..).xlsx", "\2")); Output(jobdate = Left(jobdate, 4) + "-" + Mid(jobdate, 4, 2) + "-" + Right(jobdate, 2)); Output(jobdate As date); Output(" "); return "Hello World";
