main.lua now resolves package.path relative to its own script directory rather than cwd, so the packaged install at /usr/share/lua/5.1/aish/ finds its siblings regardless of where the user invokes aish from. Dev mode (luajit main.lua from the repo root) is preserved: arg[0] is "main.lua" with no "/" so the regex returns nil and _dir falls back to "./" — identical to the previous behavior. bin/aish is a POSIX-sh wrapper that execs luajit against $AISH_LIB/main.lua (default /usr/share/lua/5.1/aish). The AISH_LIB env override lets users point at a dev checkout without uninstalling the package. Wrapper emits distinct errors when AISH_LIB is missing or when luajit isn't on PATH so broken installs surface clearly instead of through a bare sh: not found. examples/config.lua is the canonical commented reference, shipped at /usr/share/doc/aish/examples/config.lua. Stripped of the two live MCP bearer tokens carried by the in-tree config.lua and switched to the auth_env env-var indirection form; mcp.servers entries are commented out so a copy-to-~/.config/aish/config.lua produces a working starting point on first uncomment. HOSSENFELDER URL flagged as maintainer-LAN. LICENSE: MIT, copyright 2026 Markus Fritsche. README updated to match. Sonnet review of the changeset (per feedback_reviews_use_sonnet.md + bugfix-process step 4): no blockers; the two Important findings (USAGE text still said "luajit main.lua", bin/aish didn't pre-check luajit) and one Nit (unredacted HOSSENFELDER URL) were folded in before commit.

# aish
|
||
|
||
**aish** — AI-augmented conversational shell.
|
||
|
||
A single REPL that interleaves shell command execution and language-model
|
||
conversation, backed by a llama.cpp HTTP broker. Implementation is LuaJIT
|
||
2.x with FFI bindings to libcurl, GNU readline, and libc — no C extensions,
|
||
no build step, one source tree.
|
||
|
||
## Why
|
||
|
||
Three flows that currently live in three windows fold into one:
|
||
|
||
1. **"Run this command and show me the output"** — fast feedback loop, no
|
||
copy-paste between terminal and chat.
|
||
2. **"Explain or write code based on the output we just looked at"** —
|
||
exec output is automatically injected into the model's context.
|
||
3. **"Plan and execute a multi-step task with confirmation gates"** —
|
||
landing in Phase 3 as Chuck Norris autonomous mode.
|
||
|
||
aish is not a wrapper around bash. It's a first-class interactive
|
||
environment where the shell is one of several execution channels.
|
||
|
||
## Status
|
||
|
||
| Component | State |
|
||
|---|---|
|
||
| Repository skeleton | ✅ in this commit |
|
||
| Phase 0 manifest | ✅ [`docs/PHASE0.md`](docs/PHASE0.md) — locked |
|
||
| Phase 0 implementation | 🔜 next session |
|
||
| Phase 1+ | 📋 enumerated in PHASE0.md §11 |
|
||
|
||
Every module file currently raises `not implemented (Phase 0 pending)`
|
||
when called. `luajit main.lua` fails loudly at the first un-implemented
|
||
function, never silently.

## Build / runtime dependencies
|
||
|
||
System packages (Debian / ALARM / Arch names):
|
||
|
||
- `luajit` (>= 2.0)
|
||
- `libcurl4` / `libcurl-openssl-3` runtime
|
||
- `libreadline8` runtime
|
||
- `libc6` runtime (always present)
|
||
|
||
No compilation, no `luarocks`, no `make`. Just `luajit main.lua`.
|
||
|
||
## Running
|
||
|
||
Once Phase 0 ships:
|
||
|
||
```sh
|
||
luajit main.lua # uses ~/.config/aish/config.lua
|
||
luajit main.lua --config ./config.lua # explicit config path
|
||
AISH_CONFIG=/path/to/config.lua luajit main.lua
|
||
```
|
||
|
||
Config resolution order is documented in `docs/PHASE0.md` §10.
|
||
|
||
## Configuration
|
||
|
||
`config.lua` is a Lua file returning a single table. The committed
|
||
`config.lua` in this repo is both the canonical example and the
|
||
development-fallback config (lowest precedence). Copy it to
|
||
`~/.config/aish/config.lua` and edit endpoints to your local llama.cpp
|
||
servers, or point `AISH_CONFIG` at your own.
|
||
|
||
The default endpoints assume mfritsche's home network:
|
||
- `fast` → `dirac.fritz.box:8081` (Qwen2.5-Coder-7B q4 8k ctx)
|
||
- `deep` → `dirac.fritz.box:8080` (Qwen2.5-Coder-7B q4 32k ctx)
|
||
- `cloud` → `hossenfelder.fritz.box:8082` (forwards to OpenRouter)
|
||
|
||
Replace these with your own llama.cpp endpoints if you're not on that LAN.
