Crate ccalc_engine 

ccalc-engine

Core computation engine for ccalc.

This crate provides the language pipeline:

input string
    └─► tokenizer (parser::tokenize)
            └─► recursive-descent parser (parser::parse)  →  Stmt AST
                    └─► evaluator (eval::eval)  →  Value

Modules

• env — Env type, Value enum, workspace save/load
• eval — AST types, evaluator, number formatters, Base
• parser — tokenizer and recursive-descent parser, Stmt
• exec — block/loop/function executor, script search path
• io — file descriptor table for fopen/fclose/fgetl/fprintf

Modules

env

Variable environment, Value type, and workspace persistence.

eval

AST node types (Expr, Op), evaluator, and number formatters.

exec

Block statement executor: loops, functions, run/source, search path management.

io

File I/O context (IoContext) for the REPL session.

parser

Tokenizer, recursive-descent parser, and Stmt AST.
