kicad-symbol-merge 0.2.0

Merge all .kicad_sym symbol files in a folder into one KiCad library (KiCad v6+ compatible).

kicad-symbol-merge

Getting sick of downloading custom KiCad symbols one by one, only to have to manually add each as its own library?
Well, there’s an easy solution. Just merge them all into one KiCad symbol library!

---

Installation

Install directly from PyPI:

pip install kicad-symbol-merge

---

Usage

Run from the command line:

kicad-symbol-merge <source_folder> <output_file>

Example:

kicad-symbol-merge individual_symbols merged_symbols.kicad_sym

This will take every .kicad_sym file inside individual_symbols/ and merge them into a single, KiCad v6+ compatible library file called merged_symbols.kicad_sym.

---

Notes

• Supports KiCad v6, v7, and v8 .kicad_sym formats
• Works recursively in any folder you specify
• Safely removes duplicate headers and closes all parentheses properly
• Output file can be opened directly in KiCad’s Symbol Editor

---

Example Workflow

1. Download multiple symbol files (e.g., from GitHub, LCSC, SnapEDA, etc.)
2. Put them into a folder called individual_symbols
3. Run:

kicad-symbol-merge individual_symbols merged_symbols.kicad_sym

4. Add merged_symbols.kicad_sym to your KiCad global symbol libraries
