Project Status

Current state

XE is pre-alpha. The full compiler pipeline is present:

• lexer
• parser
• semantic analysis
• code generation
• CLI entrypoint

Recently completed

• fixed assignment semantics so existing variables are reassigned instead of accidentally shadowed
• added elif
• added while
• added for item in iterable
• added break and continue
• replaced silent runtime fallbacks with explicit runtime errors for invalid operations
• improved compiler diagnostics with source-line and caret rendering
• added GitHub Actions CI for build-and-test checks
• expanded integration coverage for control flow, scoping, and CLI behavior
• aligned the docs and CLI help text with actual compiler behavior

Implemented language features

• print(...)
• input(prompt)
• length(value)
• type(value)
• convert(value, target_type)
• if / elif / else
• repeat N times
• while
• for item in iterable
• break / continue
• user-defined functions
• recursion
• list literals and indexing
• arithmetic, comparison, and boolean operators
• dynamic runtime typing with semantic checks for names, arity, and loop control

Current public release line: v0.1.2

Planned work

• assignment into list elements like items[0] = 42
• else blocks for loops if you want Python-style control flow
• more built-in functions for everyday programs
• file I/O
• networking
• concurrency
• modules and import
• formatter
• debugger
• IDE support
• richer built-ins like floor, ceil, min, and max
