DESCRIPTION
Sometimes, you can't know ahead-of-time what an expression will look like, or you want those expressions to be configurable. Perhaps you've got a set of data running through your application, and you want to allow your users to specify some validations to run on it before committing it to a database. Or maybe you've written a monitoring framework which is capable of gathering a bunch of metrics, then evaluating a few expressions to see if any metrics should be alerted upon, but the conditions for alerting are different for each monitor. A lot of people wind up writing their own half-baked style of evaluation language that fits their needs but isn't complete. Or they wind up baking the expression into the actual executable, even if they know it's subject to change. These strategies may work, but they take time to implement, time for users to learn, and induce technical debt as requirements change.
Features
- Provides support for evaluating arbitrary C-like artithmetic/string expressions
- You may have cases where you want to call a function on a parameter during execution of the expression
- Functions can accept any number of arguments
- Some operators don't make sense when used with some types
- You can also do date parsing, though the formats are somewhat limited
- Expressions are parsed once, and can be re-used multiple times
Programming Language
