A Go library providing simple error handling primitives, most notably errors.Wrap for adding context and stack traces to errors without destroying the original value. It is now in maintenance mode since Go 1.13's standard errors package covers wrapping with %w.

Use cases

• add context to errors in go
• wrap errors with stack traces in go
• get the original cause of a wrapped error
• improve error messages in go applications
• debug where an error originated in go code

When to choose

• you are on Go < 1.13 and need error wrapping
• you want stack traces captured at error creation
• you maintain an existing codebase already using this package

When to avoid

• you are on Go 1.13+ and can use the standard errors package with %w wrapping
• you need actively developed features or new functionality
• you need errors.Is/errors.As compatibility features built-in
