Issues-FS

Issues-FS

A file-system based issue tracking library with hierarchical structure and pluggable storage backends.

Issues-FS stores issues as JSON files in a folder structure, enabling version control with Git, offline access, and flexible deployment options. It provides the core data layer for building issue tracking applications.

Key Features

• File-Based Storage — Issues stored as issue.json files, easily version-controlled with Git
• Hierarchical Structure — Nest issues inside other issues via issues/ subfolders
• Pluggable Backends — Works with memory, local disk, S3, SQLite, or ZIP via Memory-FS
• MGraph-DB Integration — Efficient graph queries for visualization and traversal
• Type-Safe — Built with osbot-utils Type_Safe patterns for runtime validation
• Recursive Discovery — Find issues at any depth in the hierarchy

Installation

pip install issues-fs

Quick Start

from memory_fs.Memory_FS                          import Memory_FS
from memory_fs.storage_fs.Storage_FS__Memory      import Storage_FS__Memory
from memory_fs.storage_fs.Storage_FS__Local_Disk  import Storage_FS__Local_Disk
from issues_fs.graph.Graph__Repository            import Graph__Repository
from issues_fs.graph.Node__Service                import Node__Service
from issues_fs.graph.Type__Service                import Type__Service
from issues_fs.storage.Path__Handler__Graph_Node  import Path__Handler__Graph_Node

# Setup with in-memory storage (great for testing)
storage_fs   = Storage_FS__Memory()
memory_fs    = Memory_FS(storage_fs=storage_fs)
path_handler = Path__Handler__Graph_Node(base_path='')
repository   = Graph__Repository(memory_fs=memory_fs, path_handler=path_handler)

# Or use local disk storage
storage_fs   = Storage_FS__Local_Disk(root_path='.issues')
memory_fs    = Memory_FS(storage_fs=storage_fs)
path_handler = Path__Handler__Graph_Node(base_path='')
repository   = Graph__Repository(memory_fs=memory_fs, path_handler=path_handler)

# Initialize services
type_service = Type__Service(repository=repository)
node_service = Node__Service(repository=repository)

# Initialize default types
type_service.initialize_default_types()

Core Operations

Create an Issue

from issues_fs.schemas.Schema__Node__Create__Request import Schema__Node__Create__Request

request = Schema__Node__Create__Request(
    node_type   = 'task',
    title       = 'Implement user authentication',
    description = 'Add OAuth2 support',
    status      = 'backlog',
    tags        = ['security', 'backend']
)

response = node_service.create_node(request)

if response.success:
    print(f"Created: {response.node.label}")  # Task-1

Load an Issue

from issues_fs.schemas.Safe_Str__Graph_Types import Safe_Str__Node_Type, Safe_Str__Node_Label

node = repository.node_load(
    node_type = Safe_Str__Node_Type('task'),
    label     = Safe_Str__Node_Label('Task-1')
)

print(node.title)   # "Implement user authentication"
print(node.status)  # "backlog"

Find All Issues (Recursive)

# Find all issues, including nested ones
all_nodes = repository.nodes_list_all()

for info in all_nodes:
    print(f"{info.label} ({info.node_type}) at {info.path}")

# Filter by root path
project_nodes = repository.nodes_list_all(
    root_path=Safe_Str__File__Path('data/project/Project-1')
)

Load by Path

# Load issue by folder path
node = repository.node_load_by_path(
    Safe_Str__File__Path('data/project/Project-1/issues/Version-1/issues/Task-1')
)

# Find path for a label
path = repository.node_find_path_by_label(Safe_Str__Node_Label('Task-1'))

Update an Issue

from issues_fs.schemas.Schema__Node__Update__Request import Schema__Node__Update__Request

request = Schema__Node__Update__Request(
    status = 'in-progress',
    tags   = ['security', 'backend', 'urgent']
)

response = node_service.update_node(
    node_type = Safe_Str__Node_Type('task'),
    label     = Safe_Str__Node_Label('Task-1'),
    request   = request
)

Delete an Issue

response = node_service.delete_node(
    node_type = Safe_Str__Node_Type('task'),
    label     = Safe_Str__Node_Label('Task-1')
)

MGraph-DB Integration

For efficient graph queries and visualization:

from issues_fs.mgraph.MGraph__Issues__Sync__Service import MGraph__Issues__Sync__Service
from issues_fs.mgraph.MGraph__Issues__Domain        import MGraph__Issues__Domain

# Create sync service
sync_service = MGraph__Issues__Sync__Service(
    repository   = repository,
    path_handler = path_handler
)

# Lazy load graph (syncs from filesystem)
graph = sync_service.ensure_loaded()

# Query by label
node = graph.get_node_by_label('Task-1')

# Get children
children = graph.get_children(node.node_id)

# Get ancestors (path to root)
ancestors = graph.get_ancestors(node.node_id)

# Force resync after external changes
sync_service.full_sync()

Storage Structure

Issues-FS uses a simple, human-readable folder structure:

.issues/
├── config/
│   ├── node-types.json          # Issue type definitions
│   └── link-types.json          # Link type definitions
├── data/
│   └── {type}/
│       └── {Label}/
│           ├── issue.json       # Issue data
│           └── issues/          # Child issues
│               └── {Child-Label}/
│                   └── issue.json
└── indexes/
    └── issues.mgraph.json       # MGraph-DB cache

Node Types

Default node types are created on initialization:

type_service.initialize_default_types()

{
  "types": [
    {"name": "git-repo", "display_name": "Git Repo", "color": "#6e5494", "default_status": "active"},
    {"name": "project", "display_name": "Project", "color": "#4A90D9", "default_status": "active"},
    {"name": "version", "display_name": "Version", "color": "#7B68EE", "default_status": "planned"},
    {"name": "task", "display_name": "Task", "color": "#50C878", "default_status": "backlog"},
    {"name": "bug", "display_name": "Bug", "color": "#FF6B6B", "default_status": "open"},
    {"name": "feature", "display_name": "Feature", "color": "#FFD700", "default_status": "backlog"},
    {"name": "user-story", "display_name": "User Story", "color": "#20B2AA", "default_status": "backlog"}
  ]
}

Custom Types

from issues_fs.schemas.Schema__Node__Type import Schema__Node__Type

custom_type = Schema__Node__Type(
    name           = 'epic',
    display_name   = 'Epic',
    color          = '#9B59B6',
    icon           = 'rocket',
    statuses       = ['draft', 'active', 'completed'],
    default_status = 'draft'
)

type_service.create_node_type(custom_type)
