Alternatively, we can use also LL(1) parsing in which recursion is simulated through a stack and the parser is table driven. Here I present the two formally equivalent methods, given the same set of Productions. The first implementation just prints an inverted string of an arbitrary complex C...
In a "plain" LL(k) parser (without and-predicates), the parser makes a decision and "never looks back". For example, when parsing the following LL(1) grammar: C# public rule Tokens @[ Token* ]; public rule Token @[ Float | Id | ' ' ]; token Float @[ '0'..'9'* '.' ...

gogll v3generates a matching lexer and parser. It generates GLL and LR(1) parsers. v3 compiles itself. v3 is used in a real-world project. gogll v2had the last vestiges of the bootstrap compiler grammar removed from its input grammar. v2 compiled itself. ...
Thellbuild ninjasubtool also provides additional commands which are primarily only useful for developers interested in working on the Ninja support. These commands allow testing the lexer, parser, and manifest loading components independently and are used as part of the test suite. ...
