### Automate LibrePCB Library Validation with GitHub Actions

Source: https://context7.com/librepcb-libraries/lolin.lplib/llms.txt

This YAML workflow configures GitHub Actions to automatically validate LibrePCB library integrity on every push or pull request. It uses the 'librepcb/librepcb-cli:1.1.0' Docker image to run the `librepcb-cli open-library` command with strict checking and minification.

```yaml
name: CI

on:
  push:
  pull_request:

jobs:
  check:
    runs-on: ubuntu-22.04
    container:
      image: librepcb/librepcb-cli:1.1.0
    steps:
    - uses: actions/checkout@v1
    - name: Validate Library
      run: librepcb-cli open-library --all --strict --check --minify-step .
```

--------------------------------

### Define Git Ignore Patterns for LibrePCB Project

Source: https://context7.com/librepcb-libraries/lolin.lplib/llms.txt

This .gitignore file specifies patterns for files to be excluded from Git version control. It includes common temporary files, autosave files, backups, and operating system specific files like '.DS_Store' and 'Thumbs.db', helping to keep the repository clean and focused on source code.

```gitignore
*.lp~
*.lp#
*.autosave
*.bak
*.tmp
.DS_Store
Thumbs.db
```

### Organize Lolin Packages with Category in LibrePCB

Source: https://context7.com/librepcb-libraries/lolin.lplib/llms.txt

This Lisp code defines a package category named 'Lolin' in LibrePCB for organizing package footprints. It includes metadata such as name, description, keywords, author, version, and creation date. It also specifies a parent category, enabling hierarchical organization of electronic components.

```lisp
(librepcb_package_category d48590c9-c156-40d7-960a-d72290c2d363
 (name "Lolin")

```

--------------------------------

### Configure Git for Cross-Platform S-Expression File Integrity

Source: https://context7.com/librepcb-libraries/lolin.lplib/llms.txt

This .gitattributes file configures Git to treat all files as having text line endings, preventing automatic conversion. This is crucial for maintaining the integrity of S-expression based files (like those used in LibrePCB) across different operating systems, ensuring consistent formatting.

```gitattributes
* -text
```

### Define Wemos D1 Mini Schematic Symbol in Lisp

Source: https://context7.com/librepcb-libraries/lolin.lplib/llms.txt

This Lisp code defines the schematic symbol for the Wemos D1 Mini. It specifies pin names, positions, rotations, lengths, and alignment. It also includes graphical elements like polygons for the outline and text for component name, value, and labels.

```lisp
