# hocr-spec-python Validation of hOCR close to the specs <!-- BEGIN-MARKDOWN-TOC --> * [Rationale](#rationale) * [Installation](#installation) * [Command line interface](#command-line-interface) * [API example](#api-example) <!-- END-MARKDOWN-TOC --> ## Rationale [hOCR](https://github.com/kba/hocr-spec) is a flavor of HTML for encoding the results of Optical Character Recognition (OCR) engines. It is supported by most OCR engines, such as [tesseract](https://github.com/tesseract-ocr/tesseract), [ocropus/ocropy](https://github.com/tmbdev/ocropy) and [kraken](https://github.com/mittagessen/kraken). The [hOCR specifications](https://github.com/kba/hocr-spec) is at the same time very simple (hOCR is just HTML) and hard to implement, due to its terseness and lack of up-to-date code samples. This project aims to implement the rules defined by the specs from the ground up to serve as a validation tool and reference implementation. It is meant to help hOCR implementers and support tools like [hocr-tools](https://github.com/tmbdev/hocr-tools). ## Installation Use pip: ```sh # System-wide: sudo pip install [--user] hocr-spec # For current user: pip install --user hocr-spec ``` From source: ```sh git clone https://github.com/kba/hocr-spec-python cd hocr-spec-python # System-wide: sudo python setup.py install # For current user: python setup.py install --user ``` ## Command line interface <!-- BEGIN-EVAL echo; ./hocr-spec -h |sed 's/^/ /' --> usage: hocr-spec [-h] [--format {text,bool,ansi,xml}] [--profile {relaxed,standard}] [--implicit_capabilities CAPABILITY] [--skip-check {attributes,classes,metadata,properties}] [--parse-strict] [--silent] sources [sources ...] positional arguments: sources hOCR file to check or '-' to read from STDIN optional arguments: -h, --help show this help message and exit --format {text,bool,ansi,xml}, -f {text,bool,ansi,xml} Report format --profile {relaxed,standard}, -p {relaxed,standard} Validation profile --implicit_capabilities CAPABILITY, -C CAPABILITY Enable this capability. Use '*' to enable all capabilities. In addition to the 'ocr*' classes, you can use ['ocrp_dir', 'ocrp_font', 'ocrp_lang', 'ocrp_nlp', 'ocrp_poly'] --skip-check {attributes,classes,metadata,properties}, -X {attributes,classes,metadata,properties} Skip one check --parse-strict Parse HTML with less tolerance for errors --silent, -s Don't produce any output but signal success with exit code. <!-- END-EVAL --> ## API example ```python from hocr_spec import HocrValidator validator = HocrValidator() report = validator.validate('/path/to/sample.hocr') print(report.format('xml')) # <report valid='false'>...</report> ```
