$ show tecnickcom/TCPDF
TCPDF is a PHP library for programmatic PDF generation, originally a monolithic single-file engine. The current version (7.0.7) is a compatibility facade that delegates all rendering to the modern `tecnickcom/tc-lib-pdf` engine, preserving the legacy 291-method public API while the internal engine is replaced. The library is explicitly deprecated and in maintenance-only mode; users are encouraged to migrate to `tc-lib-pdf` directly. It provides a comprehensive set of features for creating PDF documents: text and HTML rendering, images, barcodes (1D and 2D), forms, digital signatures, encryption, PDF/A compliance, and more. The codebase includes a rich test suite (PHPUnit) with a reusable base test class, a smoke test runner for all 68 example scripts, and a method-mapping tool that generates the authoritative documentation of delegation status. The deposit is a library, not a standalone application, and is intended to be integrated into PHP applications via Composer.
The LLM identified 3 files worth highlighting for reuse:
Base test class for the TCPDF test suite. Provides helper methods like `newPdf()` to instantiate a TCPDF object, `popplerTool()` to locate external PDF tools (pdfinfo, pdftotext), `extractText()` to extract text from generated PDFs, and `pdfInfo()` to retrieve metadata. This class encapsulates the common setup and validation logic for PDF testing, making it reusable for any project that needs to programmatically verify PDF output. It demonstrates sound testing patterns for binary output formats.
A standalone script that executes all 68 example scripts headlessly, checking exit codes, stderr, and PDF parseability. It generates a JSON report at `target/report/example_smoke.json`. This pattern is reusable for any library that provides example scripts: it can be adapted to smoke-test example code in a CI pipeline, ensuring examples remain functional across releases. The script is self-contained, parameterized, and produces structured output.
A tool that maintains the authoritative mapping of TCPDF public methods to their delegation status (delegated, adapter, shim, intentional-noop, blocked, stub). It uses PHP reflection to verify that all methods in the TCPDF class are accounted for and regenerates `MAPPING.md` as the single source of truth. This pattern is reusable for any large facade or deprecated API where tracking method-by-method compatibility is critical. It enforces completeness, prevents drift, and generates human-readable documentation.
