Module minify 

Code-block minifiers used by the LLM emit pass.

v0.2 shipped JSON/JSONL. v0.3 adds Rust, Go, JavaScript/TypeScript, Java, C/C++, and SQL via hand-rolled tokenizers. Each minifier is fail-closed: any parse error returns Err, and the caller falls back to verbatim emission with a B0701 warning.

Minification is required to be semantically lossless — the broad rule is parse → minify → re-parse produces structurally equal data. Where we lack a real parser we settle for tokenizer-equivalence and a hand-curated corpus of edge-case fixtures.

Modules

c_common

Shared building blocks for the C-family minifiers (Rust, Go, JS/TS, Java, C/C++, SQL). Each language module produces a Vec<Token> with its own lexer; a shared emitter consumes the stream to produce a minified string with minimal-but-safe whitespace.

c_cpp

C and C++ minifier.

go

Go minifier.

java

Java minifier.

javascript

JavaScript / TypeScript minifier.

json

JSON / JSONL minifiers (v0.2). Comment-free formats: the MinifyOptions::keep_comments flag is a no-op here.

rust

Rust minifier.

sql

SQL minifier (Postgres-flavored, the canonical dialect per spec §4.5).

Structs

MinifyError

MinifyOptions

MinifyOutput

A successful minification produces a body plus zero-or-more per-conversion warnings (e.g. B0703 line-comment-converted notices).

Enums

MinifyWarning

Per-block warnings the minifier may produce. The LLM emit pass is responsible for translating these into stderr warning[Bxxxx]: … lines.

Functions

is_supported

Returns true if lang, lowercased, is one of the minifiers shipped in this build. v0.3: json, jsonl, rust/rs, c/h, cpp/c++/cc/cxx/hpp/hxx, java, go, js/javascript, ts/typescript, sql.

minify

Dispatch to the appropriate minifier by language tag. Caller must check is_supported first; an unsupported language returns Err.

refusal_reason

If lang is a permanently-refused language (significant whitespace), return a one-line reason. Languages: python/py, yaml/yml, makefile/make/mk.
