Changed

• No longer allow keywords as index fields (generated invalid Lua code)
• Loaded compiled Lua chunks now have their source names embedded in their chunkname
  • #27
• Operator assignments no longer cause unnecessary duplicate indexing
  • #29
  • ex) my_expensive_function().x += 1 will now only call my_expensive_function once.
  • ex) a.b.c += 1 will only cause a to be indexed once.
• Erde now transforms variable names based on the scope they were declared with.
  • The most recently declared scope will always take precedence
  • ex) local x = 0; global x = 1; assert(x == 1)
• Erde now throws a parsing error when declaring a destructured variable with no value (ex. local { a };)
• Erde now throws a parsing error when using goto with an undefined label (same behavior as Lua)

Fixed

• Fixed allowing keywords as variable names
• Fixed compilation error for interpolation strings with only an escaped brace
  • #24
• Fixed return list failing to parse surround chars in strings
  • #21
• Fixed not being able to assign to the index of a function call result
  • #26
• Fixed parsing table string entry with only =
  • #28
• Fixed compilation of function declarations with Lua keywords
  • #25
• Fixed operator precedence fighting in operator assignments
  • #20
• Fixed erde compile failing when parent directories are not present
  • parent directories are now created recursively as needed
• Fixed mismatched names for Lua keywords when accessing _G or _MODULE
  • #18
• Fixed module declarations not updating _MODULE
  • #22
• Fixed continue generating invalid code when targeting 5.1(+)
  • #34
• Fixed return lists incorrectly interpreting expression commas as list commas
  • For example, returning an iife with a comma in the function body
• Fixed mangled stacktrace for bit library tail calls
  • https://www.freelists.org/post/luajit/Bad-stack-trace-from-lua-getstack-and-lua-getinfo,1

Added

• Erde will now throw a compiler error when targeting 5.1, 5.1+, or jit, and there are additional statements following a break.
  • Lua 5.1 / LuaJIT do not support statements following break (parsing error, similar to return)
  • #34
• Compiled files now include the Lua target at the bottom of the compiled file.
• Added specific error checks for common mistakes
  • ~= vs !=
  • elseif vs else if
• The Erde version is available via the API using erde.version
