Crate yog_script_analyze 

Yog Script (.ys) and Yog Nanite Script (.yns): the language a Yog mod is written in (docs/design/ys.md, docs/design/ys-grammar.md). This crate reads a source into its syntax tree, resolves its names and says what’s wrong with it, as Diagnostics placed in the source.

Modules

ast

The syntax tree of a Yog Script source (docs/design/ys-grammar.md §2).

index

The class index (docs/design/ys.md §8): what the compiler knows of the game for one Minecraft version — each class by Mojang’s name, the side it’s on, what it extends and implements, its fields and methods with their descriptors and access. Built by yog index from the game’s own jars; the resolver and the type checker look the game’s names up in it.

parser

The parser core: a cursor over tokens, problems and recovery, and the turn-taking — each form is parsed by its word (words/) or by a generic form here (types, blocks, expressions by precedence).

resolve

What the names of a source stand for, and what’s out of place: each name looked up in the scopes around it (a declaration’s anywhere in its body, a block’s from where it’s bound), declared twice, assigned while constant, break outside a loop, skip outside a before, it outside a lambda, self outside members. Names a source doesn’t declare are the game’s and the library’s: the type checker looks them up.

token

What the lexer cuts a source into: tokens, each with where it is.

words

The words of Yog Script. Each word is one file under words/: how it’s written, what it means (shown by editors) and how it parses. The parser core only hands each word its turn; this file only lists them.

Structs

Checked

A source checked: its tree, what its names stand for, its problems.

Parsed

A source read: its tree (what could be read of it) and its problems.

Functions

check

The source src of the file name read and its names resolved: what yog check and the editors report.

parse

The source src of the file name read; patches are allowed when it’s a .yns file.
