EigenScript 0.8.1

New Builtins

• monotonic_ns / monotonic_ms — high-precision monotonic timer via clock_gettime(CLOCK_MONOTONIC). Sub-millisecond precision, no fork, no shell.

Runtime

• System stdlib resolution — load_file and import now search ~/.local/lib/eigenscript/ as fallback after CWD and script-relative paths. make install copies lib/*.eigs there. External projects can use stdlib without copying files.

Documentation

• Gap analysis for real-world program classes
• ROADMAP updated with all completed features by version

Testing

• 614 tests

EigenScript 0.8.0

Runtime

• Reference counting GC — automatic memory management, Values freed when refcount hits zero
• unobserved: blocks — opt out of observer tracking for performance-critical code. In-place numeric mutation, zero allocation for arithmetic
• eval_num_fast — pure arithmetic fast path inside unobserved blocks, no intermediate Value allocation

Graphics Extension (SDL2)

• 13 builtins: gfx_open, gfx_close, gfx_clear, gfx_rect, gfx_line, gfx_point, gfx_circle, gfx_text, gfx_present, gfx_poll, gfx_ticks, gfx_delay, gfx_title
• Dynamically loads libSDL2 at runtime (no dev headers needed)
• gfx_text with embedded 5x7 bitmap font, scalable
• gfx_poll returns events as dicts with key names
• Build: make gfx

New Builtins

• Bitwise: bit_and, bit_or, bit_xor, bit_not, bit_shl, bit_shr
• I/O: write (no newline), flush, raw_key (non-blocking keypress), usleep
• String: join as C builtin — O(n) single-allocation concatenation

Testing

• 614 tests (up from 568)
• Bitwise, I/O, GC stress tests

EigenScript 0.7.1

Hardened runtime — same language, safer internals.

Internal

• strbuf: growable string buffers replace fixed MAX_STR throughout lexer, regex, JSON, REPL
• xmalloc_array: overflow-safe multiplicative allocations with safe_size_mul
• builtins_tensor.c: tensor builtins extracted into own file
• memcpy string concat: replaces strcpy/strcat in evaluator

Security

• HTTP 404 JSON injection fix
• realpath confinement for static file serving
• Dynamic request buffer with EIGS_HTTP_MAX_BODY

Testing

• 568 tests (up from 552)
• Large-buffer regression tests for strings, JSON, regex

git clone https://github.com/InauguralSystems/EigenScript.git
cd EigenScript && make install

EigenScript 0.7.0

Language

• Pattern matching: match expr: case pattern: ... with wildcard _
• Pipe operator: data |> transform |> sort
• Lambda expressions: (x) => x * 2 with closure capture
• Break/continue: proper loop control flow
• Dot-assignment: config.name is "value"
• Multiline collections: lists and dicts span multiple lines
• Regex: regex_match, regex_find, regex_replace (POSIX ERE)
• Import system: import math with namespaced access

Architecture

• Source split: eigenscript.c → lexer.c, parser.c, eval.c, builtins.c
• OOM-safe allocations, recursion depth guard, stack protector

Security

• Shell injection fix, HTTP Content-Length validation, model dimension overflow guard, softmax NaN guard

Testing

• 552 tests (up from 224) + 44 fuzz tests under ASAN+UBSan
• Formal EBNF grammar specification

Install

git clone https://github.com/InauguralSystems/EigenScript.git
cd EigenScript && make install

EigenScript 0.6.0

EigenScript is now a complete, standalone programming language.

New Language Features

• REPL — eigenscript with no args for interactive mode
• Named parameters — define add(a, b) as: replaces manual n[0]/n[1] unpacking
• String interpolation — f"Hello {name}, {x * 2}"
• Native dictionaries — {} literals, .key dot access, ["key"] bracket access
• Try/catch — try: ... catch err: ... with throw builtin
• Closures — functions capture their defining environment
• eval — execute EigenScript strings at runtime

Meta-Circular Interpreter

• lib/eigen.eigs: tokenizer, parser, and evaluator written in pure EigenScript
• EigenScript can now run EigenScript

Standard Library

• 25 modules covering math, lists, maps, sets, sorting, queues, state machines, templating, logging, CLI args, datetime, config, validation, HTTP, testing, formatting, and the meta-circular interpreter
• All modules converted to named parameters

Stats

• 127 builtins
• 25 stdlib modules
• 224 tests passing
• ~140K binary, zero dependencies

Install

git clone https://github.com/InauguralSystems/EigenScript.git
cd EigenScript

EigenScript 0.5.0

Initial public release of the C-native EigenScript runtime.

Highlights

• Observer semantics: every value tracks entropy and trajectory (improving, diverging, stable, converged, oscillating, equilibrium)
• 121 builtins: tensor math, file I/O, JSON, HTTP, database, and more
• 24 standard library modules: math, lists, maps, sets, sorting, queues, state machines, templating, logging, CLI args, datetime, config, validation, and more
• Single C binary (~96K) with no external dependencies
• Full documentation: language reference, builtin reference, stdlib guide, error diagnostics
• 121-test suite
