v1.17.7

Compare Source

Expr is a Go-centric expression language designed to deliver dynamic configurations with unparalleled accuracy,
safety, and speed.

program, err := expr.Compile(`let foo = bar(); baz(foo, foo)`)

This release brings new language features, performance improvements across runtime and compiler, better error
handling, and many important bug fixes.

New Features

Support for else if expressions

• You can now chain conditional branches using else if! (#​879)

Unicode escapes in the \u{XXXXXX} format

• String literals now support Unicode code point escapes such as \u{1F600}. (#​882)

Byte slice support in the matches operator

The matches operator now works with []byte, improving interoperability with binary data. (#​876)

Short-circuit control options

New options allow enabling or disabling short-circuiting behavior in the compiler and VM. (#​847)

Option to disable if operator

A separate DisableIfOperator option is now available. (#​881)

Performance Improvements

Runtime structure fetch improvements

Accessing struct fields at runtime is now faster. (#​833)

VM function call optimizations

Function calls inside the VM execute more efficiently. (#​832)

Type system performance boost

Large or complex type operations now run significantly faster. (#​824)

Bug Fixes

• Guard negative forward jump offsets (#​861).
• Prevent stack underflow in the VM (#​860).
• Correct behavior of AsBool with nil and undefined variables (#​866).
• Proper handling of nil arguments in variadic functions (#​868).
• Show function name for safe calls in disassembly (#​869).
• Limit recursion depth in built-in functions (#​870).
• Throw an error when a predicate is missing in the parser (#​842).
• Fixed array type resolution in conditional operator (#​865).
• Disallow access to unexported struct fields (#​846).
• Fixed retrieving field pointers in structs (#​843).
• Better error position reporting in multi-line scripts (#​827).
• Support quoting backticks inside string literals (#​820).
• Fixed auto-dereference for maps/slices and conditionals (#​871).
• Wrap merged optimizer results as predicates (#​864).
• Improved missing property handling (#​854).
• Handle invalid if conditions and detect null-byte crashes.
• Added regression tests for several reported issues.
