Pulp ZIP

ZIP helpers for Pulp packages and scripts.

Features

• Unzip in pipelines: Expand ZIP payloads from a Pulp File into regular Pulp files.
• Zip in pipelines: Collect regular Pulp files into one ZIP archive.
• Temporary file handling: Uses temporary files internally because PHP ZipArchive works with paths.

Installation

composer require mapsight/pulp-zip

Requires PHP ext-zip.

Usage

Use PulpZip::unzip() after any source handler that emits ZIP bytes:

use OpenMapsight\Pulp;
use OpenMapsight\PulpZip;

Pulp::start()
    ->pipe(Pulp::srcHttp('GET', $url, [], 'data.zip'))
    ->pipe(PulpZip::unzip('.*\.csv'))
    ->pipe(Pulp::dest(__DIR__ . '/result'))
    ->run();

unzip($patterns) emits each matching archive entry as a normal Pulp File. Patterns use Pulp's regular-expression file matching, the same as Pulp::fileSwitch().

Use PulpZip::zip() to collect incoming files into one archive:

Pulp::start()
    ->pipe(Pulp::src('.*\.json', __DIR__ . '/data'))
    ->pipe(PulpZip::zip('export.zip'))
    ->pipe(Pulp::dest(__DIR__ . '/result'))
    ->run();

Error Handling

The handlers throw RuntimeException when:

• A temporary ZIP file cannot be created.
• The ZIP archive cannot be opened.
• A ZIP entry path is unsafe, for example an absolute path or a path containing ...
• A cache or temp file cannot be read or written by the caller.

Notes

• This package intentionally keeps the API small. It is not a full archive extraction library.
• For large ZIP files, prefer combining this package with mapsight/pulp-cache so downloads are cached before parsing.
