# Bafishka - Fish Shell + Clojure File Operations

🐟 Rust-native Fish shell-friendly file operations with Steel-backed SCI Clojure evaluation.

## Repository
- **Source**: https://github.com/bmorphism/bafishka
- **Language**: Clojure (SCI) + Rust
- **Seed**: 1069 (deterministic)

## Core Concept

Bafishka bridges Fish shell ergonomics with Clojure's data processing power:

```fish
# Fish shell with Clojure evaluation
baf '(map inc [1 2 3])'  # => [2 3 4]

# File operations with Clojure
baf '(fs/glob "**/*.clj" | count)'  # => 42
```

## Architecture

## Key Features

### Steel Backend
Steel is a Rust Scheme implementation providing:
- Fast native execution
- Seamless Rust FFI
- Async I/O support

### SCI Clojure
Small Clojure Interpreter for:
- Full Clojure core library
- REPL evaluation
- Babashka compatibility

## Usage Examples

```fish
# List files with Clojure processing
baf '(->> (fs/list-dir ".")
         (filter #(str/ends-with? % ".md"))
         (map fs/file-name))'

# JSON processing
baf '(-> (slurp "data.json")
         json/parse-string
         :items
         count)'

# With deterministic seed (1069)
baf '(gay/color 1069)'  # Deterministic color
```

## Integration with plurigrid/asi

### With gay-mcp
```clojure
;; File operations with color coding
(defn colored-ls [dir]
  (->> (fs/list-dir dir)
       (map (fn [f] 
              {:file f 
               :color (gay/color (hash f))}))))
```

### With duckdb-ies
```clojure
;; Query DuckDB from bafishka
(baf '(duck/query "SELECT * FROM files WHERE mtime > now() - interval 1 hour"))
```

## Configuration

```fish
# ~/.config/fish/conf.d/bafishka.fish
set -gx BAF_SEED 1069
set -gx BAF_HISTORY ~/.baf_history
alias baf 'bafishka eval'
```

## Scientific Skill Interleaving

This skill connects to the K-Dense-AI/claude-scientific-skills ecosystem:

### Graph Theory
- **networkx** [○] via bicomodule
  - Universal graph hub

### Bibliography References

- `general`: 734 citations in bib.duckdb



## SDF Interleaving

This skill connects to **Software Design for Flexibility** (Hanson & Sussman, 2021):

### Primary Chapter: 5. Evaluation

**Concepts**: eval, apply, interpreter, environment

### GF(3) Balanced Triad

```
bafishka (−) + SDF.Ch5 (−) + [balancer] (−) = 0
```

**Skill Trit**: -1 (MINUS - verification)

### Secondary Chapters

- Ch4: Pattern Matching
- Ch2: Domain-Specific Languages

### Connection Pattern

Evaluation interprets expressions. This skill processes or generates evaluable forms.
## Cat# Integration

This skill maps to **Cat# = Comod(P)** as a bicomodule in the equipment structure:

```
Trit: 0 (ERGODIC)
Home: Prof
Poly Op: ⊗
Kan Role: Adj
Color: #26D826
```

### GF(3) Naturality

The skill participates in triads satisfying:
```
(-1) + (0) + (+1) ≡ 0 (mod 3)
```

This ensures compositional coherence in the Cat# equipment structure.
