New parser
The LPeg parser has been replaced. The grammar is defined in
moonscript/parse/grammar.moon and compiled by
pgen into a native C module,
moonscript.parse.native. A pure Lua version of the same grammar is included
as moonscript.parse.slow, a drop-in replacement for the native module; it
is not selected automatically.
Parsing is around 5x faster:
| Interpreter | LPeg parser | New parser | Speedup |
|---|---|---|---|
| Lua 5.1.5 | 0.947s | 0.180s | 5.3x |
| LuaJIT 2.1 | 0.817s | 0.141s | 5.8x |
(Parse time for a 405 file, 58,296 line corpus, best of 5 passes.)
The parser produces the same syntax trees as the LPeg grammar. Other changes:
- Parse error messages have a new format:
<message> at line <n>, column <m>:followed by the offending line and a^marker, replacingFailed to parse: [<n>] >> <line>. Anything matching on the old error text will need updating. - Installing the rock now compiles a C module, so a C compiler is required at install time.
moonscript.parseno longer exportsbuild_grammarandextract_line, and themoonscript.parse.util,moonscript.parse.literalsandmoonscript.parse.envmodules have been removed.- The
MOONSCRIPT_PARSERenvironment variable is no longer used. - LPeg is still a dependency:
moonscript.errorsandbin/moon-tagsuse it for parsing unrelated to MoonScript source.
MoonScript v0.7.0 (2026-07-26)
This update includes a bunch of syntax bug fixes and cleanups, with a few new features and an enhanced linter. This will be the last release using LPeg, future versions will use the new parser.
Destructuring updates
Function arguments can be destructured
A function argument can now be written as a table literal to destructure the
value passed in. The destructuring patterns are the same ones supported by
assignment, including nested patterns, numeric keys, and @field targets:
dist = ({x: x1, y: y1}, {x: x2, y: y2}) -> math.sqrt (x2 - x1)^2 + (y2 - y1)^2 class Point new: ({x: @x, y: @y}) => render = (name, {:width, :height}, scale=1, ...) -> print name, width, height, scale, ...
The argument becomes an internal name and the fields are unpacked at the top of the function body:
render = function(name, _arg_0, scale, ...) local width, height width, height = _arg_0.width, _arg_0.height if scale == nil then scale = 1 end return print(name, width, height, scale, ...) end
Destructured arguments always declare fresh locals, so a name in the pattern shadows an enclosing local of the same name instead of assigning to it.
Argument initialization now happens in the order the arguments are written, so a default value can reference a name that an earlier argument destructured:
scaled = ({:base}, amount = base * 2) -> base + amount
Because the destructured names are bound at the top of the body, a name in a
pattern can not collide with another argument. ({:a}, a) -> and ({:self}) =>
are now compile errors.
Destructuring in multiple assignment
Destructuring can now be used mixed in with other names in multiple assignment (#367, #304):
num, {:message} = two_values! head, {:content}, tail = mix! {value: built}, {:status} = builder\build!
Previously the assignment was split into separate statements, which broke destructuring output.
Better validation of destructuring targets
The names extracted by a destructuring pattern are now checked with the same
rule the parser uses for assignment targets. @@class_field, index expressions,
and slices are now allowed:
{x: obj.a, y: obj["b"], z: @prop, w: @@cls_prop} = t
Destructuring into something that can never be assigned to is now a compile error instead of generating broken code:
{foo!} = thingreportsCan't destructure into chain ending in call{...} = thingreportsCan't destructure into '...'
Linter updates
Lint stages
The linter's checks are now organized into named stages: global_access,
unused, constant_assign, and import_overwrite. Every stage runs by
default. moonc --lint-stage limits reporting to the named stage, and
--exclude-lint-stage reports everything but the named stage. Both options can
be repeated, and they can not be combined.
moonc -l --lint-stage global_access --lint-stage unused . moonc -l --exclude-lint-stage import_overwrite .
New checks
import_overwrite reports an import that clobbers a name that is already
bound in scope:
insert = "hello" f = -> import insert from table -- import overwrites existing binding `insert`
constant_assign reports writing to a name that is tagged as constant. In this
version, only the names created by import are tagged as constant. For this
release, constant names are only checked in the linter. In the future we will
make constant violation a compiler error.
import insert from table insert = 5 -- assigning to constant `insert`
Compact lint output
moonc --lint-format compact writes one line per issue in the familiar
file:line:column: message shape, with the stage name appended, for editors
and tools that parse compiler output (#465):
$ moonc -l --lint-format compact lint_example.moon
lint_example.moon:7:5: accessing global `my_nmuber` [global_access]Standard library updates
New class introspection functions
The moon module has four new functions, documented in the standard
library reference:
is_class(value)tests if a value is a MoonScript class tableis_instance(value)tests if a value is an instance of a MoonScript classis_instance_of(value, cls)tests if a value is an instance ofclsor any of its parents. It throws an error ifvalueis not an instanceis_subclass_of(cls, parent)tests ifclsinherits fromparent. A class is not a subclass of itself. It throws an error ifclsis not a class
Unlike the old is_object, these can tell classes, instances, and __base
tables apart.
is_object is now deprecated. It returns truthy for instances, classes, and
__base tables, so it can not be used to distinguish them.
BREAKING: moon.type no longer returns the class object for a class
moon.type now returns the string "class" when given a class, and it only
returns the class object for actual instances. Previously a class returned
itself, and a __base table returned the class it belonged to, which made it
impossible to tell an instance from the class it came from.
class MyClass type MyClass! -- MyClass (unchanged) type MyClass -- "class" (was MyClass) type MyClass.__base -- "table" (was MyClass)
BREAKING: changes to moonscript.util
These are internal helpers that were never documented, but they were reachable:
util.moon.typeis nowutil.mtype, to avoid the confusion with thetypefunction in themoonmoduleutil.moon.is_objectremoved, replaced byutil.moon.is_classandutil.moon.is_instanceutil.moon.is_aremoved, replaced byis_instance_ofin themoonmodule
Code Generation
Interpolated strings and nested expressions are parenthesized correctly
The compiler now knows Lua's operator precedence when writing out an expression, and it adds parentheses when a nested expression would otherwise be regrouped by the surrounding operators. String interpolation is the most common way to get a nested expression, and it was silently generating the wrong math (#320):
x = 10 / "#{b}.5"
Before:
local x = 10 / tostring(b) .. ".5"
After:
local x = 10 / (tostring(b) .. ".5")
Because .. is right associative in Lua, an interpolated string on the left
hand side of a .. is grouped as well. This is observable through the
__concat metamethod:
prefix = "id: #{id}, " .. rest
Before:
local prefix = "id: " .. tostring(id) .. ", " .. rest
After:
local prefix = ("id: " .. tostring(id) .. ", ") .. rest
Prefix operators are grouped in update assignments and switches
The check for whether a value needs to be wrapped in parentheses did not
account for the prefix operators #, -, not, and ~, which parse greedily.
An update assignment or a switch case with one of them on the left would
compile to the wrong grouping (#457):
count -= #datum + 1 total *= -x + 1 flag and= not a or b
Before:
local count = count - #datum + 1 local total = total * -x + 1 local flag = flag and not a or b
After:
local count = count - (#datum + 1) local total = total * (-x + 1) local flag = flag and (not a or b)
Expression lines no longer use _
When an expression appears where a statement is expected, the compiler assigns
it to a throwaway variable. It used to use the name _, which would clobber a
variable of that name in the user's code (#309). It now uses an autogenerated
_scrap_N name.
_ = 5 tbl.field print _
Before:
local _ = 5 _ = tbl.field return print(_)
After:
local _ = 5 local _scrap_0 = tbl.field return print(_)
local in a class body is hoisted
A local declaration inside a class body was written out near the bottom of the
generated do block, after the methods had already been compiled. Methods
referencing the name would close over the outer or global name instead of the
class local (#459). The declaration is now hoisted to the top of the class body,
placed after the reference to the parent class so a body local can shadow the
parent's name.
class Counter local cache -- previously `cache` local would not be lexically available in the method update: => cache or= "something..."
Bug Fixes
- Updated all compiler thrown errors to ensure they include positional information so the error messages are more informative
- Trailing
continuein a loop body generated invalid Lua (breakwas followed by more statements) a, b = x\some_methodand other assignments of a single complex value to multiple names silently dropped every name after the first- A
\stubwithout a base crashed the compiler with an internal error. Inside awithblock it now uses thewithvalue, and outside of one it reportsShort-colon syntax must be called within a with block(#428) continueoutside of a loop is now a compile error with a line number instead of an internal error with a traceback- Destructuring against the result of an

...,nil,not thing,#thing, or a table literal, generated invalid Lua - An expression inside a string interpolation that can't be parsed now throws a parse error instead of putting the malformed code as raw characters in the string
- Fixed broken
moonc --versionwhich reported missing argument instead of printing version (#471) - Errors raised without a position now report the position of the statement being compiled, instead of no position at all
- An internal compiler error no longer throws a second error while trying to report the first one
Binaries
-
The static binaries now report build information with
--version:$ moon --version MoonScript version 0.7.0 (static build) Runtime: LuaJIT 2.1.1748459687 Commit: v0.7.0 Built: 2026-07-24T09:07:45-07:00 -
LuaJIT builds are now included alongside the Lua 5.1 builds
-
Linux arm64 builds are now included
New Parser in Testing
The next version of MoonScript will likely include the new C parser generated by pgen, replacing LPeg. Early testing shows the new parser is be about 5x faster.
Setting the MOONSCRIPT_PARSER=pgen environment variable will make the
compiler parse with the moonscript_parser module instead of building the LPeg
grammar at runtime. This is opt in and experimental, the LPeg grammar is still
the default

my_func( "first arg" => print "some func" "third arg", "fourth arg" )
Function argument definitions
Just like the function all update, function argument definitions have no whitespace restrictions between arguments, and line breaks can be used to separate arguments:
some_func = ( name type action="print" ) => print name, type, action

- Code coverage not being able to find file from chunk name
MoonScript v0.4.0 (2015-12-06)
Changes to super
super now looks up the parent method via the class reference, instead of a
(fixed) closure to the parent class.
Given the following code:
class MyThing extends OtherThing the_method: => super!
In the past super would compile to something like this:
_parent_0.the_method(self)
Where _parent_0 was an internal local variable that contains a reference to
the parent class. Because the reference to parent is an internal local
variable, you could never swap out the parent unless resorting to the debug
library.
This version will compile to:
_class_0.__parent.__base.the_method(self)
Where _class_0 is an internal local variable that contains the current class (MyThing).
Another difference is that the instance method is looked up on __base instead
of the class. The old variation would trigger the metamethod for looking up on
the instance, but a class method of the same name could conflict, take
precedence, and be retuned instead. By referencing __base directly we avoid
this issue.
Super on class methods
super can now be used on class methods. It works exactly as you would expect.
class MyThing extends OtherThing @static_method: => print super!
Calling super will compile to:
_class_0.__parent.static_method(self)
Improved scoping for super
The scoping of super is more intelligent. You can warp your methods in other
code and super will still generate correctly. For example, syntax like this
will now work as expected:
class Sub extends Base value: if debugging => super! + 100 else => super! + 10 other_value: some_decorator { the_func: => super! }
super will refer to the lexically closest class declaration to find the name
of the method it should call on the parent.
Bug Fixes
- Nested
withblocks used incorrect ref (#214 by @geomaster) - Lua quote string literals had wrong precedence (#200 by @nonchip)
- Returning from

MoonScript v0.3.0 (2015-2-28)
New Features
- New unused assignment linter finds assignments that are never referenced after being defined.
Parsing Updates
Whitespace parsing has been relaxed in a handful of locations:
- You can put unrestricted whitespace/newlines after operator in a binary operator before writing the right hand side. The following are now valid:
x = really_long_function! + 2304 big_math = 123 / 12 - 43 * 17 bool_exp = nice_shirt and cool_shoes or skateboard and shades
- You can put unrestricted whitespace/newlines immediately after an opening parenthesis, and immediately before closing parenthesis. The following are now valid:
hello = 100 + ( var * 0.23 ) - 15 funcall( "height", "age", "weight" ) takes_two_functions (-> print "hello" ), -> print "world"
- You can put unrestricted whitespace/newlines immediately after a
:when defining a table literal. The following is now valid:
x = { hello: call_a_function "football", "hut" }
Code Generation
- Single value
import/destructurecompiles directly into single assignment
Bug Fixes
- Some
moonccommand line flags were being ignored - Linter would not report global reference when inside self assign in table
- Fixed an issue where parser would crash in Lpeg 0.12 when compiling hundreds of times per process

@when loading code so stack traces tread it as file - Fix bug where
moonccouldn't work with absolute paths - Improve target file path generation for
moonc
MoonScript v0.2.5 (2014-3-5)
New Things
- New code coverage tool built into
moonc - New linting tool built into
moonc, identifies global variable references that don't pass whitelist - Numbers can have
LLandULLsuffixes for LuaJIT
Bug Fixes
- Error messages from
mooncare written to standard error - Moonloader correctly throws error when moon file can't be parsed, instead of skipping the module
- Line number rewriting is no longer incorrectly offset due to multiline strings
Code Generation
Bound functions will avoid creating an anonymous function unless necessary.
x = hello\world
Before:
local x = (function() local _base_0 = hello local _fn_0 = _base_0.world return function(...) return _fn_0(_base_0, ...) end end)()
After:
local x do local _base_0 = hello local _fn_0 = _base_0.world x = function(...) return _fn_0(_base_0, ...) end end
Explicit return statement now avoids creating anonymous function for statements where return can be cascaded into the body.
-> if test1 return [x for x in *y] if test2 return if true "yes" else "no" false
Before:
local _ _ = function() if test1 then return (function() local _accum_0 = { } local _len_0 = 1 local _list_0 = y for _index_0 = 1, #_list_0 do local x = _list_0[_index_0] _accum_0[_len_0] = x _len_0 = _len_0 + 1 end return _accum_0 end)() end if test2 then return (function() if true then return "yes" else return "no" end end)() end return false end
After:
local _ _ = function() if test1 then local _accum_0 = { } local _len_0 = 1 local _list_0 = y for _index_0 = 1, #_list_0 do local x = _list_0[_index_0] _accum_0[_len_0] = x _len_0 = _len_0 + 1 end return _accum_0 end if test2 then if true then return "yes" else return "no" end end return false end
MoonScript v0.2.4 (2013-07-02)
Changes
- The way the subtraction operator works has changed. There was always a little confusion as to the rules regarding whitespace around it and it was recommended to always add whitespace around the operator when doing subtraction. Not anymore. Hopefully it now works how you would expect. (
a-bcompiles toa - band nota(-b)anymore). - The
moonlibrary is no longer sets a global variable and instead returns the module. Your code should now be:
moon = require "moon"
- Generated code will reuse local variables when appropriate. Local variables are guaranteed to not have side effects when being accessed as opposed to expressions and global variables. MoonScript will now take advantage of this and reuse those variable without creating and copying to a temporary name.
- Reduced the creation of anonymous functions that are called immediately. MoonScript uses this technique to convert a series of statements into a single expression. It's inefficient because it allocates a new function object and has to do a function call. It also obfuscates stack traces. MoonScript will flatten these functions into the current scope in a lot of situations now.
- Reduced the amount of code generated for classes. Parent class code it left out if there is no parent.
New Things
- You can now put line breaks inside of string literals. It will be replaced with
\nin the generated code.
x = "hello world"
- Added
moonscript.basemodule. It's a way of including themoonscriptmodule without automatically installing the moonloader. - You are free to use any whitespace around the name list in an import statement. It has the same rules as an array table, meaning you can delimit names with line breaks.
import a, b c, d from z
- Added significantly better tests. Previously the testing suite would only verify that code compiled to an expected string. Now there are unit tests that execute the code as well. This will make it easier to change the generated output while still guaranteeing the semantics are the same.
Bug Fixes
bis not longer treated as self assign in{ a : b }- load functions will return
nilinstead of throwing error, as described in documentation - fixed an issue with
moon.mixinwhere it did not work as described
MoonScript v0.2.3-2 (2013-01-29)
Fixed bug with moonloader not loading anything
MoonScript v0.2.3 (2013-01-24)
Changes
- For loops when used as expressions will no longer discard nil values when accumulating into an array table. This is a backwards incompatible change. Instead you should use the
continuekeyword to filter out iterations you don't want to keep. Read more here. - The
moonscriptmodule no longer sets a global value formoonscriptand instead returns it. You should update your code:
moonscript = require "moonscript"
New Things
- Lua 5.2 Support. The compiler can now run in either Lua 5.2 and 5.1
- A switch
whenclause can take multiple values, comma separated. - Added destructuring assignment.
- Added
local *(andlocal ^) for hoisting variable declarations in the current scope - List comprehensions and line decorators now support numeric loop syntax
Bug Fixes
- Numbers that start with a dot, like
.03, are correctly parsed - Fixed typo in
foldlibrary function - Fix declaration hoisting inside of class body, works the same as
local *now

MoonScript 0.1.0 (2011-08-12)
Initial release
