### Manage LibrePCB Library with Bash commands

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

This Bash script demonstrates common command-line operations for managing the LibrePCB library. It includes validation of library structure and components, checking for definition errors, exporting documentation, searching for specific components using grep, and counting components by category.

```bash
# Validate library structure and components
librepcb-cli open-library --all --strict --minify-step .

# Check for errors in component definitions
librepcb-cli open-library --all --strict .

# Generate library documentation
librepcb-cli open-library --export-docs ./docs .

# Search for specific components
find cmp -name "component.lp" -exec grep -l "STM32F4" {} \;

# Count components by category
grep -r "category" cmp/ | cut -d'"' -f2 | sort | uniq -c
```

### Configure CI for LibrePCB Library Validation with YAML

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

This YAML configuration sets up a Continuous Integration workflow for the LibrePCB library on GitHub Actions. It specifies the CI trigger events (push, pull_request), the operating system, and a Docker container (librepcb/librepcb-cli) to run the validation using the `librepcb-cli` tool. The `--strict` flag ensures that validation is thorough.

```yaml
name: CI
on: [push, pull_request]
jobs:
  check:
    runs-on: ubuntu-22.04
    container:
      image: librepcb/librepcb-cli:1.0.0-rc1
      options: --entrypoint /bin/bash
    steps:
    - uses: actions/checkout@v1
    - run: librepcb-cli open-library --all --strict --minify-step .
```

### Define Symbol for STM32L4 MCU in Lisp

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

This Lisp code defines a schematic symbol for a specific STM32L4 microcontroller. It includes pin configurations, graphical elements like polygons and text for names and values, and metadata such as name, description, keywords, author, and creation date. This definition is crucial for representing the component accurately in PCB schematics within LibrePCB.
