UniLoader imports KiCad components from downloaded ZIPs or extracted folders, including SamacSys, UltraLibrarian and SnapMagic. Run it manually or watch your download folder throughout your graphical login session.

It supports symbols, footprints and referenced STEP/VRML models, with:

Global (UniLoader_Global) and project-local (UniLoader_Local) library nicknames, created and registered automatically.
A destination dialog offering detected KiCad project suggestions, Global and Browse.
Conservative exact footprint reuse and comparison dialogs for uncertain matches.
Broken model-path repair, explicit ambiguous model choices and missing-model warnings.
Preserved source archives, pending import retries, backups and import history.

Quick start

Linux requires Rust 1.95 or newer and the usual desktop graphics libraries. The binary includes egui/eframe dialogs; rfd file browsing uses the desktop's XDG portal. notify-send is optional. See the setup guide for packages, configuration, recovery and the shipped systemd user service.

cargo build --release --locked
install -Dm755 target/release/uniloader ~/.local/bin/uniloader
~/.local/bin/uniloader import /path/to/component.zip --project /path/to/Board/Board.kicad_pro --dry-run
~/.local/bin/uniloader import /path/to/component.zip --project /path/to/Board/Board.kicad_pro
~/.local/bin/uniloader watch

A default configuration is generated on first launch at ${XDG_CONFIG_HOME:-~/.config}/uniloader/config.toml. The existing minimal config remains supported:

[libraries]
path = "~/KiCad/libraries"
# For global imports, choose your actual installed KiCad version if detection
# finds none or more than one:
# kicad_config = "~/.config/kicad/9.0"

See the complete configuration example. Project imports create libraries beside the .kicad_pro file using ${KIPRJMOD} paths; KiCad may need a library refresh or reopen. Missing models are reported and mean that a component is not yet fully portable.

uniloader import /path/to/component.zip --global
uniloader import /path/to/extracted-folder --project /path/to/Board/Board.kicad_pro
uniloader pending
uniloader retry IMPORT_ID
uniloader discover

No-argument startup also runs the watcher. --noninteractive leaves unresolved choices pending; --force on manual imports deliberately revisits a completed source. Check an imported component in KiCad before using it in a board.

Check and repair libraries (v0.2.3)

Close KiCad and stop the watcher, then preview and apply repairs:

uniloader doctor --global
uniloader doctor --global --fix
uniloader doctor --project /path/to/Board/Board.kicad_pro
uniloader doctor --project /path/to/Board/Board.kicad_pro --fix

Repeat the project commands for each existing project. Project repair also checks and repairs the configured global libraries. Doctor recreates missing managed folders, empty symbol libraries and table entries, repairs owned registration paths and nicknames, and checks component and model references. It repairs model paths when a unique matching file is available. Deleted components require restoring or reimporting with --force; doctor reports unresolved issues and exits nonzero, including after applying safe repairs. Changed files are backed up; see the setup guide. Reopen KiCad afterwards.

Scope

This is practical Linux development tooling. Project discovery currently uses process arguments and working directories as suggestions; check the selected path. KiCad IPC discovery, tray controls, comparison overlays and automatic undo are follow-ups. Legacy .lib conversion and CAD-format conversion are outside the current release. The preview is approximate; inspect unusual footprints in KiCad. The specification records the intended behavior and delivery priorities.
