A Go library for evaluating arbitrary C-like arithmetic and string expressions at runtime, with support for parameterized expressions. It lets applications accept user-defined or configurable expressions instead of hardcoding logic.

Use cases

• evaluate user-defined expressions in go
• configurable validation rules for data
• evaluate alerting conditions from metrics
• parse and evaluate math expressions with parameters
• build a rule engine in golang
• runtime expression evaluation instead of hardcoding logic

When to choose

• you need safe, sandboxed evaluation of arithmetic/string/boolean expressions in Go
• expressions must be configurable at runtime or supplied by users
• you want parameterized expressions evaluated against a map of values

When to avoid

• you need a full scripting language with control flow, functions, or loops
• you want an actively maintained project - the repository is archived
• you need expression evaluation in a language other than Go
