# Geolog Development Notes
This document describes the features and components added to the geolog project (by me, Hassan).
## Overview
Geolog is a language for geometric logic - a type theory with semantics in topoi and geometric morphisms, designed as a unified language for database schemas, queries, and migrations.
## Components
### Core Components (Pre-existing)
- **Parser & Lexer** (`src/lexer.rs`, `src/parser.rs`) - Chumsky-based parser for geolog syntax
- **AST** (`src/ast.rs`) - Abstract syntax tree representation
- **Core Types** (`src/core.rs`) - Signatures, structures, theories, axioms
- **Elaboration** (`src/elaborate.rs`) - Type checking and elaboration
- **Store** (`src/store.rs`) - Append-only persistent storage with version control
- **REPL** (`src/repl.rs`) - Interactive command-line environment
- **Solver** (`src/solver.rs`) - Model enumeration for geometric theories
- **Query Engine** (`src/query/`) - Relational algebra backend for queries
- **Chase Algorithm** (`src/query/chase.rs`) - Fixpoint computation for axiom closure
### Debugger (`src/debugger.rs`)
Interactive debugger for the chase algorithm providing:
- Step-through execution
- Breakpoints on axiom name patterns
- Variable inspection
- Iteration stepping
Usage in REPL:
```
:debug-chase <instance> [max_iterations]
```
### GUI Application (`src/gui/`)
A full-featured graphical interface built with egui.
#### Building the GUI
```bash
# Build with GUI feature
cargo build --features gui
# Run the GUI
cargo run --features gui --bin geolog-gui
# With workspace persistence
cargo run --features gui --bin geolog-gui -- -d ./myproject
# Load a file on startup
cargo run --features gui --bin geolog-gui -- examples/preorder.geolog
```
#### GUI Architecture
```
src/gui/
├── mod.rs # Module exports
├── app.rs # Main GeologApp (egui::App implementation)
├── state.rs # GuiState wrapping ReplState
├── panels/
│ ├── mod.rs
│ ├── browser.rs # Theory/instance tree browser
│ ├── editor.rs # Code editor with line numbers
│ ├── inspector.rs # Detail view for selected items
│ └── console.rs # Output/error messages
└── visualizations/
├── mod.rs
├── chase.rs # Chase step-through visualization
└── graph.rs # Relation graph visualization
```
#### GUI Features
**Browser Panel (Left)**
- Tree view of all theories and instances
- Filter/search functionality
- Click to select, right-click for context menu
- Shows counts (sorts, functions, relations, axioms, elements)
**Editor Panel (Center Top)**
- Multi-line code editor
- Line numbers
- Run button (or Ctrl+Enter) to execute code
- Clear button
**Inspector Panel (Center Bottom)**
- Theory details: parameters, sorts, functions, relations, instance fields, axioms
- Instance details: elements by sort, function values, relation tuples, nested instances
- Collapsible sections
- "View Graph" button for instances
**Console Panel (Bottom)**
- Scrollable message log
- Color-coded messages: info (gray), success (green), error (red), warning (orange)
- Auto-scroll option
- Clear button
**Chase Visualization**
- Step/Run All/Stop controls
- Events log showing axiom firings with bindings
- Breakpoint management
- Current structure info (elements, relation tuples)
- Mode indicator (Idle/Stepping/Running/Completed)
**Graph Visualization**
- Nodes represent elements (colored by sort)
- Edges represent relation tuples
- Interactive: drag nodes, zoom (scroll), pan
- Relation filter dropdown
- Reset Layout / Fit buttons
- Hover to see sort name
#### UI Layout

## CLI Commands
### REPL Commands
```
:help [topic] Show help (topics: syntax, examples)
:quit Exit the REPL
:list [target] List theories/instances
:inspect <name> Show details of a theory or instance
:source <file> Load and execute a geolog file
:clear Clear the screen
:reset Reset all state
# Version Control

```
### CLI Usage
```bash
# Start REPL (in-memory)
cargo run
# Start REPL with workspace persistence
cargo run -- -d ./myproject
# Load file on startup
cargo run -- examples/preorder.geolog
# Show help
cargo run -- --help
```
## Dependencies
### Core Dependencies
- `chumsky` - Parser combinators
- `ariadne` - Error reporting
- `uuid` - Unique identifiers
- `rkyv` - Zero-copy serialization
- `rustyline` - Readline for REPL
- `indexmap` - Ordered hash maps
### GUI Dependencies (feature = "gui")
- `eframe` - egui framework with native window
- `egui_extras` - Additional egui widgets
- `rfd` - Native file dialogs
## Example
```geolog
// Define a preorder theory
theory Preorder {
X : Sort;
leq : [a: X, b: X] -> Prop;
// Reflexivity
forall x : X. |- [a: x, b: x] leq;
// Transitivity
forall x : X, y : X, z : X.
[a: x, b: y] leq, [a: y, b: z] leq |- [a: x, b: z] leq;
}
// Define an instance
instance Chain3 : Preorder = {
bot : X;
mid : X;
top : X;
[a: bot, b: mid] leq;
[a: mid, b: top] leq;
}
```
Then run `:chase Chain3` to compute the transitive closure.
## Development
```bash
# Check without GUI
cargo check
# Check with GUI
cargo check --features gui
# Run tests
cargo test
# Build release
cargo build --release --features gui
```
