datasheets-md (dsmd, dBsync)

A git-like working copy of your datasheets.md workspace: the parts' unified parameters, pin tables and CAD configuration as plain text files you can grep, edit and push back, plus the workspace's KiCad library.

pip install datasheets-md             # the dsmd CLI
pip install datasheets-md-gui         # CLI + the dBsync desktop app (adds PySide6 to an existing install)

Ubuntu/Debian refuse a system-wide pip install ("externally-managed-environment"). Install into a venv and link the command onto your PATH:

python3 -m venv ~/.venvs/dsmd && ~/.venvs/dsmd/bin/pip install datasheets-md
ln -s ~/.venvs/dsmd/bin/dsmd ~/.local/bin/dsmd

or let pipx do both: pipx install datasheets-md.

dsmd looks for a new release once a day and prints one line when there is one. dsmd self-update upgrades the install the way it was made (pipx, uv tool, or the pip of its venv). Set DSMD_NO_UPDATE_CHECK=1 to turn the check off; it also stays off under CI, with --json or --quiet, and when stderr is not a terminal.

A clone of a large workspace can stop part way (network, Ctrl-C, a closed laptop) without losing what it downloaded: files reach the disk as they arrive, and running the same dsmd clone command again continues it. Until it finishes, dsmd status says so and fetch, pull and push refuse. If only the library step fails, the parts and datasheets are in place, dsmd exits with code 2, and dsmd pull --library (or the next dsmd pull) builds library/.

Use

dsmd login                            # browser sign-in (DSMD_TOKEN=dsh_... for headless use)
dsmd workspaces                       # pick one
dsmd clone "My workspace" lib && cd lib
dsmd status                           # what you changed
dsmd diff                             # ... as a diff
dsmd push -m "Fix VOH typ from page 5"
dsmd pull                             # server changes, merged row by row
dsmd log [PART]                       # server-side history
dsmd part add SN74HC00N [--manufacturer TI]
dsmd part rm SN74HC00N
dsmd pdf SN74HC00N                    # PDF into .dsmd/cache/
dsmd open SN74HC00N                   # the part's web page
dsmd categories                       # catalogue category ids, for mapping files
dsmd feedback "a setting I need"      # tell the datasheets.md team (--kind bug|suggestion)
dsmd gui                              # the desktop app (needs datasheets-md-gui)
dsmd self-update                      # upgrade to the latest release (--check only asks)
dsmd confirm <part> [item ...]        # confirm CAD review items or rows; push sends them
dsmd help agents                      # the guide for AI agents

Every command takes --json, --quiet and -C <dir>. Exit codes: 0 ok, 1 error, 2 done but with conflicts or stale/rejected parts.

DSMD_SERVER (or --server) points at another instance, e.g. https://api-dev.datasheets.md.

The working copy

.dsmd/                        state, pristine base copies, cache (gitignored)
dsmd.toml                     what to pull, which library outputs to build
settings/mappings/*.yaml      every workspace mapping (categories, parameter names, CAD fields, active_for) -- edit, add or delete a file, admin
settings/symbol_style.yaml    symbol generation settings and reference designators     -- editable, admin
parts/<MFR>/<PN>/
  part.yaml                   identity, and `datasheet:` -> its datasheet.md (read-only)
  parameters.jsonl            unified parameters, one row per line  -- editable
  pins.csv                    physical pins, one per line           -- editable
  cad.yaml                    CAD configuration                     -- editable
datasheets/<MFR>/<PDF name>/  one per family, shared by its parts
  datasheet.md                digitised datasheet with its element ids (read-only)
  images/                     the figures datasheet.md links to (read-only)
library/                      generated KiCad library (rebuilt on pull)
  datasheets.sqlite, datasheets.kicad_dbl, datasheets.kicad_sym,
  datasheets.pretty/, sym-lib-table, fp-lib-table

How it differs from git: one remote, no branches, no staging or local commits. push is applied atomically per part; the server may normalise what you pushed and sends the result straight back. Merges are by row key (k) and pin id, so edits to different rows never conflict. History lives on the server.

To use the library in KiCad, open library/ as a project folder (the lib tables point at the symbols and footprints) or add datasheets.kicad_dbl as a database library (needs the SQLite ODBC driver).

Develop

pip install -e ".[gui,test]"
pytest

Standalone dBsync binaries (no Python needed) are built by .github/workflows/build.yml with PyInstaller from packaging/dbsync.py.
