dirsql (Python SDK)
Ephemeral SQL index over a local directory. dirsql watches a filesystem, ingests structured files into an in-memory SQLite database, and exposes a SQL query interface -- the filesystem is always the source of truth.
Also available as dirsql on crates.io and dirsql on npm.
Installation
pip install dirsql
Requires Python >= 3.12. Ships as a native extension (Rust via PyO3); prebuilt binary wheels are provided for common platforms.
Quick start
DirSQL is async by default: the constructor returns immediately, scanning runs in a background thread, and you await db.ready() before querying. Each table is a (ddl, glob, extract) triple: the DDL defines the SQLite schema, the glob selects files (relative to the root), and extract turns a matched file into a list of row dicts. dirsql does not read file contents -- if extract needs the file body it reads path itself; return an empty list to skip a file.
import asyncio
import json
from dirsql import DirSQL, Table
async def main():
db = DirSQL(
"./my-blog",
tables=[
Table(
ddl="CREATE TABLE posts (title TEXT, author TEXT)",
glob="posts/*.json",
extract=lambda path: [json.loads(open(path, encoding="utf-8").read())],
),
],
)
await db.ready()
posts = await db.query("SELECT * FROM posts WHERE author = 'alice'")
print(posts)
asyncio.run(main())
Multiple tables and joins
db = DirSQL(
"./my-blog",
tables=[
Table(
ddl="CREATE TABLE posts (title TEXT, author_id TEXT)",
glob="posts/*.json",
extract=lambda path: [json.loads(open(path, encoding="utf-8").read())],
),
Table(
ddl="CREATE TABLE authors (id TEXT, name TEXT)",
glob="authors/*.json",
extract=lambda path: [json.loads(open(path, encoding="utf-8").read())],
),
],
)
await db.ready()
results = await db.query("""
SELECT posts.title, authors.name
FROM posts JOIN authors ON posts.author_id = authors.id
""")
Ignoring files
Pass ignore patterns to skip files during scanning and watching:
db = DirSQL(
"./my-blog",
ignore=["**/drafts/**", "**/.git/**"],
tables=[...],
)
Path-table scans (SELECT ... FROM './') respect .gitignore files by
default. Pass no_ignore=True to restore the full walk; the built-in
node_modules/.git defaults and any ignore patterns still apply:
db = DirSQL("./my-blog", no_ignore=True)
Loading SQLite extensions
Pass extensions to load SQLite extension shared libraries onto the connection at startup (before any CREATE TABLE). Each entry is a dict with a path and an optional entrypoint init-symbol override:
db = DirSQL(
"./my-blog",
tables=[...],
extensions=[
{"path": "./ext/vec0.dylib", "entrypoint": "sqlite3_vec_init"},
{"path": "./ext/myext.so"}, # entrypoint derived from the filename
],
)
await db.ready()
# The extension's functions are now callable in queries:
rows = await db.query("SELECT vec_version() AS v")
dirsql enables extension loading only while loading the configured libraries, then disables it again, so the SQL load_extension() function is never exposed to your queries. Programmatic entries load first, followed by any [[dirsql.extension]] entries declared in a config file. See the config reference.
Watching for changes
db.watch() returns an async iterator of row-level change events as files change on disk:
async for event in db.watch():
print(f"{event.action} on {event.table}: {event.row}")
if event.action == "error":
print(f" error: {event.error}")
Each event has .action ("insert", "update", "delete", or "error"), .table, .row (the new row, or the deleted row on delete), .old_row (the previous row, on update), .file_path, and .error (on error).
CLI
pip install dirsql also installs a dirsql console script. dirsql "<sql>" (or uvx dirsql "<sql>") runs one query and prints the rows as JSON — the default. dirsql server starts an HTTP server exposing the SDK over HTTP: POST /query for SQL and GET /events for a Server-Sent Events change stream. See the CLI reference.
