Execute a parser

Parse a string directly

Parse Garry's mod Lua tokens to an abstract syntax tree. Also returns parse errors

Region start to SourcePos

Region end to SourcePos

SourcePos to region

LineColPos to SourcePos

SourcePos to LineColPos

Update a SourcePos with an MToken

Match a token

Get the source position Simply gets the position of the next token Falls back on the collected position when there is no token left

Get the source position Simply gets the end position of the last parsed token

A thing of which the region is to be parsed

Parses the full AST Its first parameter contains all comments Assumes the mtokens fed to the AParser have no comments

Parse a block with an optional return value

Parser that is interleaved with 0 or more of the other parser

Parse a return value

Label

Parse a single statement

Global definition Note: Uses try to avoid conflicts with function calls

Local definition

Global function definition

Local function definition

Parse if then elseif then else end expressions

Parse numeric for loop

Generic for loop

Function name (includes dot indices and meta indices)

Local function name: cannot be a meta function nor indexed

Parse a number into an expression

Parse any kind of string

Parse an identifier

Parse a list of identifiers

Parse variable list (var1, var2, var3)

Parse local variable list (var1, var2, var3)

Parse list of function parameters

list of expressions

Subexpressions, i.e. without operators

Separate parser for anonymous function subexpression

Parse operators of the same precedence in a chain

Parse unary operator (-, not, #)

Parses a binary operator

Operators, sorted by priority Priority from: http://www.lua.org/manual/5.2/manual.html#3.4.7

Parse chains of binary and unary operators

Prefix expressions can have any arbitrary list of expression suffixes

Prefix expressions The suffixes define rules on the allowed suffixes

Parse any expression suffix

Parse an indexing expression suffix

Parse an indexing expression suffix

Function calls are prefix expressions, but the last suffix MUST be either a function call or a metafunction call

single variable. Note: definition differs from reference to circumvent the left recursion var ::= Name [{PFExprSuffix}* indexation] | '(' exp ')' {PFExprSuffix}* indexation where "{PFExprSuffix}* indexation" is any arbitrary sequence of prefix expression suffixes that end with an indexation

Arguments of a function call (including brackets)

Table constructor

A list of table entries Grammar: field {separator field} [separator]

Parse a named field (e.g. {named = field}) Contains try to avoid conflict with unnamed fields

A field in a table

Field separator, either comma or semicolon

Optional field separator, returns NoSep when no separator is found Used at the end of a field list
