ob-elixir Implementation Tasks

This directory contains step-by-step implementation tasks for building the ob-elixir package.

Overview

The implementation is organized into 4 phases:

Phase	Description	Tasks	Priority
Phase 1	Core MVP	01-06	Critical
Phase 2	Sessions	07	High
Phase 3	Mix Integration	08	High
Phase 4	Advanced Features	09-10	Medium/Low
Phase 5	Literate Programming	11-13	Medium

Task List

Phase 1: Core (MVP)

These tasks implement the minimum viable product - basic Elixir code execution in org-mode.

Task	Title	Time	Status
01	Project Setup	30 min	Pending
02	Basic Code Execution	1-2 hrs	Pending
03	Variable Injection	1-2 hrs	Pending
04	Error Handling	1 hr	Pending
05	Result Formatting	1-2 hrs	Pending
06	Comprehensive Test Suite	2-3 hrs	Pending

Phase 1 Deliverables:

• Execute Elixir code with C-c C-c
• :results value and :results output work
• :var header arguments work
• Errors are properly reported
• Lists become org tables
• Comprehensive test coverage

Phase 2: Sessions

Task	Title	Time	Status
07	IEx Session Support	3-4 hrs	Pending

Phase 2 Deliverables:

• :session name creates persistent IEx sessions
• Variables and modules persist across blocks
• Session cleanup commands

Phase 3: Mix Integration

Task	Title	Time	Status
08	Mix Project Support	2-3 hrs	Pending

Phase 3 Deliverables:

• :mix-project path executes in project context
• Auto-detection of Mix projects
• :mix-env sets MIX_ENV
• Sessions with Mix (iex -S mix)

Phase 4: Advanced Features

Task	Title	Time	Status
09	Remote Shell (remsh)	2-3 hrs	Pending
10	Async Execution	3-4 hrs	Pending

Phase 4 Deliverables:

• :remsh node@host connects to running nodes
• :async yes for non-blocking execution

Phase 5: Literate Programming Enhancements

Task	Title	Time	Status
11	Fix Error Display in Buffer	1 hr	Pending
12	Imports Block Support	1-2 hrs	Pending
13	Module Definition Blocks	2-3 hrs	Pending

Phase 5 Deliverables:

• #+BEGIN_IMPORTS elixir blocks for shared imports/aliases
• :module ModuleName header for defining reusable functions
• Multiple blocks with same :module merge their functions
• Functions available via explicit imports in subsequent blocks

Implementation Order

Phase 1 (Must complete in order)
├── 01-project-setup
├── 02-basic-execution
├── 03-variable-injection
├── 04-error-handling
├── 05-result-formatting
└── 06-test-suite

Phase 2 (After Phase 1)
└── 07-session-support

Phase 3 (After Phase 1, can parallel with Phase 2)
└── 08-mix-project-support

Phase 4 (After relevant dependencies)
├── 09-remote-shell (after 07)
└── 10-async-execution (after Phase 1)

Phase 5 (After Phase 1, builds on 12)
├── 11-fix-error-display-in-buffer
├── 12-imports-block-support
└── 13-module-definition-blocks (after 12)

Time Estimates

Phase	Estimated Time
Phase 1	8-12 hours
Phase 2	3-4 hours
Phase 3	2-3 hours
Phase 4	5-7 hours
Phase 5	4-6 hours
Total	22-32 hours

Getting Started

1. Start with Task 01: Project Setup
2. Complete Phase 1 tasks in order
3. Phases 2-4 can be done based on your priorities

Task Template

Each task file includes:

• Objective: What the task accomplishes
• Prerequisites: What must be done first
• Steps: Detailed implementation steps with code
• Tests: Test cases to verify the implementation
• Acceptance Criteria: Checklist of requirements
• Troubleshooting: Common issues and solutions

Testing

Run tests after each task:

make test

For integration tests with org-mode:

make test-integration
